Tips to Prevent Summer AC Failure

Your Standby in the Summer

Keeping your air conditioner in top shape around the summer is an important practice. While the good weather means plenty of fun and activities to be had outside, having your air conditioner ready at home can provide you with a cool, dry refuge from the heat. Whether it’s taking a break from the sun, or trying to get comfortable before going to sleep, dropping the temperature by a couple degrees can feel like a blessing. But, without proper handling of your HVAC services, your air conditioner runs the risk of running inefficiently or giving out. Siv Air has got you covered with highly qualified repair technicians to get your air conditioner back up and running in case of a problem, there are plenty of tips and tricks we recommend at home to keep your air conditioner from landing you in an inconvenient situation.

Keep A Scheduled Service Date For Your Air Conditioner

When winter comes to a close, it can help to have a regularly scheduled tuneup of your HVAC services.. The lifespan of your air conditioner depends on the regularity that a technician inspects and services your unit to ensure that you are getting optimal air flow and that all the parts to your air conditioner are in working condition.

Clean and Replace Your Air Filter Regularly

As your air conditioner cycles the air through your home, old air passes through an HVAC filter. This filter helps to catch particles and pollutants in the air that may not only damage the air conditioner itself, but your health as well! Make sure to familiarize yourself with the filter that your air conditioner uses. There are often several grades of filter, specialised for use in the homes of people with allergen sensitivity, respiratory disease, or other special circumstances. Some of these filters can be cleaned, and some can’t, so be sure to check the directions on maintaining each filter.

A general rule of thumb is to check your filter every 90 days, or about half that time with pets in the house. You can easily associate this kind of maintenance with other regular household duties, major house cleaning or making rent or credit payments.

Personal Air Conditioner and Duct Maintenance

Besides changing your air filter, there are many things you can do to keep your air conditioner in peak condition without a visit from your AC specialist.

When changing your filter, inspect the duct and vent to ensure that each is clean and free of obstruction, such as dust buildup. Any duct that runs to a room of your home can be similarly inspected by simply removing the vent cover and checking inside to make sure everything is clean and functional. Don’t forget that your vent cover often has an option to open or close slightly to change the amount of air flow, and should be adjusted accordingly.

Checking these ducts can also help expose any air leaks or early signs of pest invasion, before they become problems. Gaps in the ducting can be easily repaired with a roll of aluminum tape, and will help reduce the workload placed on your air conditioner. Evidence of pest activity, such as droppings, can be addressed with traps or a call to a pest control specialist.

Your air conditioner itself can also be inspected and maintained with ease. For instance, you can check the coolant pipes that run to your air conditioner, and ensure that they are free of tears or decomposure. Old insulation material can be replaced just as easily as an air filter. If you use an outdoor air conditioner unit, you should also make sure to keep the surrounding area free and clear of any obstruction. Keep the unit raised above any grass or dirt at the base by at least a few centimeters, and make sure not to keep any plants or other objects within half a meter of the air conditioner.

You can also inspect morer in-depth issues with your unit:

  • Check your air conditioner for excess moisture, which may be associated with a clogged condensation line. Keeping this moisture under control can help prevent other damages such as mould.
  • While the air conditioner is off, check the wiring in the condensing unit of the air conditioner for signs of wear or fraying, which will help prevent electrical failure.
  • Inspect the fins of the condenser coils to make sure they are straight and clean.

These matters will likely require the attention of an HVAC professional, but at least you can get an idea of where problems may be lurking ahead of time and save yourself headaches in the long run!

Simple Home Insulation and Reducing Energy Use

When the hot weather approaches, the best measures to take in reducing the workload of your air conditioner are to keep the cool air in and hot air out. Keep doors and windows closed up tight, and make sure they are properly insulated. Close any curtains or blinds you may have on your windows, to keep radiant heat from the sun out. You may also opt for window treatments, which reduce the amount of heat that passes through them.

Try not to use anything in your home that would generate heat during the day. This includes running the oven or stove, or even having too many lights on. You may also choose a low or no heat option when washing dishes or clothes. Generally, reducing the amount of energy your home is using while the air conditioner is running will also help deter electrical issues and reduce costs.

You may also use additional fans, such as a ceiling fan or standing fan, to help cycle the air in a room. However, it should be noted to keep tabs on the energy being used, and only operate these fans in rooms that are occupied.

Smart Air Conditioner Use

Keeping the air conditioner from overworking itself can be difficult to approach, especially for those who plan to go out during the day. There’s no reason to leave the air conditioner running if nobody is at home. However, you also shouldn’t turn the air conditioner on too low later in the day, when it’s already hot, as it takes a lot of energy to cool a hot room than to keep a room cool.

You may opt for a programmable thermostat, which will help keep the pressure off your air conditioner by simply raising the temperature by a few degrees when the house will be empty, then it can begin cooling things off about a half of an hour before your return. Using more manual means, it helps to cool off the house in a graduated manner. Start at a few degrees under the current temperature, and slowly decrease the temperature by half of an hour.

Tips for Keeping Your AC Bill Low

Whether you’re trying to be more “green” or simply save yourself some money, lowering your power bill is an excellent idea. If you’ve been turning off lights and running a few loads of wash, but still haven’t seen a drop in your costs, you probably want to look at your AC! Even small problems with your air conditioner can cause your electric bill to get higher. Here’s what to look for and how to save more money every month.

Check Your Filter

Most air conditioner manufacturers recommend that you change the filter anywhere from twice a year to every few months. However, if you have a lot of children or pets, or if you live in a dusty area, you may need to change it more often.

A clogged filter prevents proper airflow, which makes your air conditioner work harder. As a rule of thumb, the harder it works, the higher your bills! Make things easier and cheaper by changing your filter regularly.

Set Your Thermostat Higher

We all love a cold blast of air when it’s blazing hot outside, but if you’re trying to cool your home, take it easy. The more that your AC tries to counteract warm temperatures, the harder it works. (And remember, that means higher bills!)

A single degree can have exponential effects on your energy usage. If it’s 30 degrees outside and you’ve set your thermostat to 20, your AC is spending a lot of power to adjust the temperature. By raising your thermostat just one degree to 21 degrees, you can save up to 10% on your bill! You probably won’t even notice the difference.

Don’t Run the AC While You’re Out or Asleep

If no one is at home, you can afford to set your thermostat a bit higher. Remember, every degree can save you money! You don’t need to turn off the system entirely: raising your thermostat a few degrees is sufficient to keep the AC from kicking on while you’re not at home. Once you’re back, simply set the thermostat to your desired temperature. Modern thermostats are programmable so you can automatically turn up the AC while you’re at work.

And at night, you can take advantage of naturally cooler temperatures. There’s no need to run the AC to sleep comfortably. If you need a breeze, invest in a fan or open a couple of windows to allow a cross current. This simple trick can save you money every single night!

Add Shade to Your Home

As the sun pours in, your home naturally gets warmer. Your AC will automatically kick on as the temperature rises. By maintaining the interior temperature, you can spare your air conditioner the trouble — and help your power bill! The easiest way to do this is to add shade.

Invest in sun-blocking curtains, hedges, shutters, or other methods to keep out the heat. Pay special attention to the windows that face the rising sun: those will heat up your home quickly if you’re not careful! Remember, every moment that the AC is running, it’s costing more energy. By keeping the temperature as stable as possible, you can save both energy and money.

Check Your System for Dirt and Leaks

Leaky ductwork and filthy coils both spell higher AC bills. Your system works by transferring heat to the evaporator coils, then passing the resulting cool air throughout your home’s ducts. If either of these components are dirty or leaking, your system will have to work much harder to keep your home cool.

Dirty coils don’t work as efficiently, which means the system stays on longer as it attempts to pump refrigerant to cool the air. And if your ducts are leaking cool air into your attic, the system just keeps chugging along until the air reaches your desired temperature. If you hear your system running all the time or your home never seems to get cool, dirty coils and/or leaky ducts are the likely culprits.


Reducing your AC bill starts with some simple modifications to your home and lifestyle. However, if your bills are still higher or if you suspect your system is dirty or leaking, it’s time to call in the experts. Proper air conditioner cleaning and maintenance will also help reduce your bills — plus prolong the life of your AC, which saves you money in the long run.

Repair or Replace – AC Tips That Could Save You Money

How Your Air Conditioner Could Be Costing You

Air conditioning units can be expensive, but they’re also a nightmare when they don’t work properly. Contrary to popular belief, it’s often more cost effective to get a new AC unit rather than continue repairing your old one. In this article, we’ll discuss some of the reasons why this is the case and warning signs that your old AC unit could be on its way out.

Lower Efficiency

All AC units have a energy rating. The higher the number of stars, the higher the efficiency.  The lower the number of stars, the more power the AC unit needs to function. Today, top of the line AC units have 4 or 5 stars. Depending on how old your unit is, your SEER may be as low as 1.

Wrong Size

Your AC unit could also be either too big or too small, and both can lead to inefficient heating. A licensed professional from Siv Air can come to your home and assess what size unit you need. They can also assess the efficiency of the airflow in your house.

Expensive Repairs

Older units need more repairs than new units do. It’s just a fact. Ultimately, the cost of a new unit will be outstripped by the repairs you would have had to do on the old unit anyway. A new AC unit should only need biannual repairs done. An old AC unit can rack up the bills if you need to replace a new part every time it’s serviced. However, if your unit is under warranty and you can have the repairs covered that way, or your warranty only requires you to pay labour costs, then you may want to simply use the warranty until it expires.


If you do upgrade to a new AC unit, there may be rebates or discounts in store for you. Sometimes certain cities will offer incentives to upgrade your HVAC efficiency, and manufacturers and utility companies can offer rebates too. Do some research to see what kind of deals you can get in your town when installing a new AC unit.

Environmental Costs

Older AC units run on R22 gas, which depletes ozone. Hence, the government taxes it fairly heavily in order to discourage people from buying it. So if you’re investing in a new AC unit, you’re also saving yourself money that way.

When to Buy a New Unit

Now that we’ve established how a new AC unit can save you money, there’s the all-important question of “How do I know it’s time to replace my air conditioner?” Here are some signs that you may need to send your old AC unit to the afterlife (please have it responsibly recycled in order to protect the environment).

Age of the Unit

Typically, an air conditioner lasts about 10 years, so if your AC Unit has become a temperamental teenager, it’s probably worth replacing it. And if the outside part of the unit is rusty? It’s definitely time for a new one. The fan can’t work properly if it’s corroded and brittle, and you don’t need rust and debris going into your vents.

Cost of Maintenance is Greater Than Cost of Replacement

Here’s a helpful formula to determine whether or not you need to replace your unit: if the cost of your most recent or prospective AC repair multiplied by the age in years of the unit is greater than the cost of a new AC unit, then it’s time to replace it. For example, if your repair is going to cost you $500, and your unit is 15 years old, 500 x 15 = $7,500. A new AC unit typically costs around $5,000, so in this case, it’s more cost effective to simply replace the unit rather than repair it.

High Energy Bills

If your energy bills have been going up consistently but your utility company hasn’t changed its rates, this is a sign that your AC is doing, well, less with less.

It’s Just Not Cutting It Anymore

Older AC units sometimes just can’t keep up with modern needs. For example, rising environmental temperatures can render an older AC unit obsolete. A larger unit that runs more often is also less efficient than a smaller unit that runs less often, and AC units nowadays tend to be smaller. Additionally, old AC units can become noisy as they overexert themselves in order to keep up their duties. This is a sign that a replacement may be needed.

Health Hazards of a Dirty AC Unit

How a Dirty Air Conditioner Can Harm Your Family’s Health

It’s easy to forget about your air conditioner. If you’re able to breathe easily inside your home and you change the filter regularly, no problem, right? Not necessarily. Your air conditioner is essentially your home’s lungs, constantly collecting and filtering dust, hair, and more. Dirt accumulates over time, and before you know it, the air starts to smell a little funky. By then, you’re already breathing in years’ worth of debris. Yuck! A dirty air conditioner can negatively impact your family’s health, which is why a deep cleaning may be in order.

Poor Air Quality Leads to Respiratory Issues

If you have allergies, you probably want your home to be a safe refuge from pollen and other allergens. But if your air conditioner is dirty, it’s likely circulating those problematic particles throughout your home. Your filter can only do so much. If your AC is dirty, your allergies could be aggravated and you could experience other symptoms, such as frequent sneezing and coughing.

Dirty ACs can also raise your risk of respiratory disease. Studies have shown that they can contain everything from pesticides to heavy metals to dust mite feces. Constantly breathing in particles of mould, dust, dander, pollen, and synthetic materials can damage your airways and contribute to lasting health problems.

Dirty ACs Attract Pests

You likely clean your home and garage regularly to prevent rats, roaches, and other vermin from moving in. But what’s happening above the ceiling? Dirty ACs are the perfect breeding ground for pests who can then make their way into your home. Worse, they leave droppings and dander, and you could end up breathing in particles from that nastiness.

Also, these animals often carry pathogens and allergens, so their presence could make you sick even if you never come into direct contact with them. If your air conditioning system is dirty, you likely have some unwelcome and filthy house guests. And if they die inside your ACs, you’re in for some disgusting smells and potential pathogen spread.

Clogged Coils and Filters Lead to Moisture Build-up

Ideally, your home’s interior stays nice and dry. Your air conditioner plays a big role in that. When the evaporator coils are dirty, the condensation produced as the unit cools your home will accumulate. If you have a split system, you could have your drain back up with water, causing moisture to spread throughout the home.

As you might imagine, this causes some serious problems. High humidity levels make your ACs ideal for mould and mildew, which can contribute to respiratory problems. Bacteria such as Legionella also love warm, damp environments, and you definitely don’t want to breathe those in. Also, a dirty air conditioner will have to work harder, which means it’s likely to operate less efficiently — and therefore get even dirtier.

How to Clean Your Air Conditioner

As you can see, changing your filter is not nearly enough. Think of your air conditioner as a car. With regular use, its parts wear down and get clogged or dirty. You wouldn’t drive many kilometres every day and never change the oil or tires, right? Yet many people let their air conditioners go years without a proper cleaning.

The air wells, coils and barrel fans are the main areas where dirt can accumulate. This means that the unit itself wont’ work as well, and you’re inviting mould, vermin, and pathogens to take up residence within the system. Dust and debris don’t go away on their own. To get rid of them, you need to make aircon servicing a regular part of your home maintenance.

To fully protect and clean your system, you’ll need a professional air conditioner cleaning service. They have special equipment and techniques to remove debris and restore your air conditioner’s full functionality. If you’ve never had a deep cleaning done and you’ve had your system for at least a year, you’re definitely overdue.


Don’t delay — the health hazards of dirty aircons can sneak up quickly! A dirty air conditioner presents major concerns for your health and safety, and the problem won’t go away without professional treatment. Changing your filter is not enough. For optimal indoor air quality, call in professionals to deep clean your system. If it’s been a while, we recommend hydro cleaning, which allows all parts of the system to be cleaned spotless.

For professional air conditioning in the Cairns area, reach out to Siv Air. Our hydro cleaning service includes a complete inspection of your system and advanced sanitation techniques. It’s time to start breathing easier. Request an appointment today!

Does My Air Conditioner Need to be Cleaned?

Your air conditioning system circulates air throughout your home — and with it, plenty of dust and debris. That’s why it’s important to clean your air filter regularly. But does your air conditioning unit need a deeper clean?

Is your air conditioner dirty?

If you’ve been noticing higher power bills, strange odours in your home, or that your air conditioner simply isn’t keeping your home at a comfortable temperature, it may need repair — or it could just be dirty. Your system moves a lot of air throughout your home, picking up dust and dirt particles along the way. And because the system uses water to work, it’s susceptible to mould and mildew.

The truth is, while air filters play an important part in the function of your air conditioner, they won’t prevent dirt, mildew, and mould from accumulating on your system. Several components, such as the barrel fan, coils, and drainage system can collect buildup and impair your air conditioner’s function. This can happen even if you change/clean your filters. In time, the unit stops performing effectively, increasing your costs and failing to keep your home cool.

Why you should get your air conditioner cleaned

A blocked air conditioner is unhealthy and inefficient. For example, the evaporator coil plays a major role in cooling your home. If they’re coated in dirt, they simply won’t be able to function. Without a thorough cleaning, your air conditioner’s components will eventually need extensive repair which can be costly. By getting your system cleaned before it’s too late, you can spare yourself additional repairs or more extensive replacements later.

And remember, your air conditioner is blowing air throughout your home. If it’s coated in dust, mould, and allergens, your indoor air quality will significantly decrease. You may notice a musty or mildewy smell, and you could experience symptoms such as headaches, allergies or respiratory issues.

So, what can you do to keep yourself and your family comfortable and safe?

How to clean an air conditioner

Most air conditioning systems rarely get the deep clean they need, because their components are buried within your home’s structure. That’s why it’s a good idea to call in a professional to get the job done right.

In a nutshell, you should clean/change your filters every 3 months and have your air conditioners professionally cleaned every 1-2 years, depending on your usage. HVAC pros recommend a hydro clean.

What is involved with hydro cleaning?

A hydro clean is an in-depth process that improves your air conditioner’s efficiency and safety. Here are the basic steps your aircon servicing professional will take. At Siv Air, we ensure a thorough and safe hydro clean service, including:

  • Remove and clean all air conditioner covers and filters.
  • Perform the hydro cleaning of internal air conditioner components: barrel fan, evaporator coils, condensate drain pan, louvers, and fan blades. This removes any build-up and microbes that could be affecting your system.
  • Check for the correct amount of refrigerant to ensure that your system can effectively cool your home.
  • Check that all fans are operating correctly so that air can be moved without causing build-up.
  • Measure the electric current draw of the unit (volts and amps) to determine its efficiency.
  • Treat the air conditioner with all-natural tea tree products to kill microbes at no risk to your home’s occupants.

It’s time to get your air conditioner cleaned

While filter replacement is a basic part of air conditioner maintenance, it’s not enough to keep your system — and your family — healthy. A deep cleaning will prolong the life of your air conditioner and prevent odours, allergens, and dirt from spreading around your home. Plus, an efficient system will reduce your utility bills.

To schedule a hydro cleaning that improves the function of your air conditioner, contact Siv Air and get your air conditioner performing like new again. In addition to cleaning your system, we use Environmental Air Solutions natural products to prevent harmful build-up of microbes and pathogens in your aircon system. Keep your home comfortable and your family safe: book us today.

Hydro Service What It Is and Why Your Aircon Is Begging For It

We Love Air Conditioning Service As Much As You Love Your Air Conditioner

There are days where your air conditioner can seem like your best friend. But unfortunately, that “best friend” produces condensation and can therefore be a breeding ground for mould, mildew, and other allergens, especially in a hot, wet climate like we have in Cairns.

Regular maintenance is the key to not only maintaining the life of your air conditioner, but it’s also essential to your own health. Cleaning your filters every three months is important, but every year or two you need a thorough air conditioning cleaning. Microbial contamination — bacteria, mould, and fungi that can grow inside a dirty air conditioner — can be detrimental to your health and especially harmful for children or those who suffer from asthma or allergies.

The presence of mould in your air conditioner can cause wheezing, watery eyes, coughing, or even rashes or hives. The great news is that a little regular maintenance is all it will take to save your family from microbial contamination, as well as make your air conditioner last years longer. Some of the maintenance you can do on your own, but you will need a cleaning by the professional team at Siv Air every year or two.

Your Air Conditioner Needs More Than Clean Filters

Cleaning and replacing air conditioner filters is something many homeowners know how to do themselves.

To clean your aircon’s filters, turn off the unit, remove the filter, and use a vacuum attachment to clean the dust off of them. If they are washable, you can soak them for an hour in a solution of half water and half white vinegar, and then allow them to dry thoroughly before replacing them. If the filter isn’t washable or has sustained damage, it’s time to replace it. Again, this process should be completed every three months.

As important as this is, maintaining your air conditioner properly requires more than replacing its filters. A thorough, professional cleaning is necessary to truly eliminate harmful microbes and extend the life of your aircon.

The Experts on How to Clean Your Air Conditioner

Every one to two years, your air conditioner needs to be thoroughly serviced. If you have a smoker in the home or have pets, the unit will need more frequent cleaning.

At Siv Air, we don’t just clean your air conditioners we service them. A Hydro Service is more thorough than typical aircon servicing and can clean parts of your air conditioning unit not achievable by hand.

When Siv Air arrives to clean your air conditioner, we first provide a thorough assessment of what is and is not needed for your unit. Each factor is taken into account and the status is presented to you with recommendations.

If a Hydro Service is in order, we will remove the air conditioner cover and filters and take them outside for a thorough cleaning. We will then inspect the evaporator coil for contamination or evidence of icing.

As we begin the Hydro Service process, a large waterproof bag is placed under your air conditioner to collect the runoff and prevent any damage to the surrounding area. This means your air conditioning unit can stay in place, preventing any unnecessary wear and tear on it.

We then treat the barrel fan, evaporator coils, condensate drain pan, louvers, fan blades, covers, and casing with a tested and safe chemical solution specifically designed to kill microbial contamination and rinse away clean.

Once the solution has had a chance to kill the mould, fungi, and bacteria, we pressure wash all parts of the unit with a specially designed, battery-operated pressure washer until the air conditioner is thoroughly cleaned and 100% safe for use.

A Clean Aircon Is Not the End

Our air conditioner cleaning service doesn’t end when the unit is clean. Siv Air is proud to treat each unit we service with products from Environmental Air Solutions. Locally made here in Cairns with pure Australian tea tree oil, EAS products help inhibit the regrowth of mould spores, fungi, and bacteria on your air conditioning unit. Tea tree oil is noted for its antiseptic, antibacterial, antifungal, anti-inflammatory, and antiviral properties.

Once we’ve got your unit cleaned up and mould-treated, we inspect your refrigerant level and refill it as necessary. We ensure your fans operate correctly and check the electrical draw of the unit. Finally, we even inspect your remote controls to ensure they are in proper working order.

Why Does Your Aircon Need a Hydro Service?

1.   You’ll breathe easier.

The mould and bacteria that form in your unit become airborne each time it is turned on, and your health suffers for it. This is especially true for children or those who are ill, or asthma or allergy sufferers.

The Hydro process allows us to kill microbes, fungi, and bacteria even in parts of your unit that aren’t serviceable by hand. So in the end, not only will your air conditioning unit be cleaner, but so will the air you breathe in your home.

2.   You’ll save on your energy bill and experience cooler air.

Neglecting necessary maintenance will cause a significant decline in air conditioning performance, causing energy use (and your bill!) to steadily increase.

A dirty air conditioner has to work much harder to cool the air, costing you significantly more on your energy bill each month. A clean coil and fan have a higher volume of air passing through them, meaning they cool the air far more easily. A clean aircon is a happy aircon, and a more environmentally responsible one at that.

A Hydro Service will potentially pay for itself over time on your energy bill, so when you’re saving money and looking out for your family’s health, there are no drawbacks.

3.   Your unit will work better and last longer.

Any time your air conditioner is running, it’s getting dirty. Thorough air conditioning service is required to keep it running at peak performance and efficiency.

Cleaning your filters is necessary, but it just isn’t enough. Just like your car needs regular oil changes and tune-ups, your air conditioner needs regular professional service to maintain its life span.

4.   Hydro Servicing may prevent property damage.

Blocked drains from your air conditioner can cause water leaks, potentially damaging your unit or the surrounding area, or in some cases even causing electrical shorts that can lead to fires.

How to Protect Your AC During a Storm

It never hurts to be prepared. This is especially true when it comes to protecting your air conditioning unit.

Your AC is a big investment, and it is important to take steps to protect it during a storm. Let’s first take a look at some of the important details about power surges and outages:

Power Surge vs. Power Outage

Let’s go into detail about a power surge vs. a power outage. Each of these can damage your electronics, but they are two very different things.

A power outage is when there isn’t any electricity flowing into your home. The problem could be something on your end, such as bad wiring or a break somewhere. However, most times this happens because there is a breakdown at the power station or something happened to the electric lines running to your house.

A power outage over a large area, such as a few streets or a whole town, is known as a blackout. There is also the brownout, which is when the power dips for a few moments. This will cause the lights to dim for a second or two.

The power surge is the opposite of a blackout or brownout. Instead of too little power coming in, there is too much. Most homes receive electrical power at 240 volts. So most electronics and appliances are manufactured to handle this amount of power.

Sometimes a much more powerful current gets sent through the power lines. This could be due to a lightning strike causing a sudden rise in power or a problem somewhere along the power line. When this happens, your home has much more power than the 230 volts that it can regulate and it can cause major issues.

The Power Surge Effect on Your Air Conditioner

A power surge could have a devastating effect on your air conditioning unit and end up costing you a lot of money.

Here’s how it happens:

Your air conditioning unit has capacitors inside of it. These control how much power the unit will get at any moment. They can only handle so much power and if they receive too much they will get overloaded and, ultimately, fried. Once they stop working, whatever they’re powering will stop working as well.

How to Protect Your Aircon Unit

Now that we know the extent of the danger to your aircon, let’s take a look at the steps you should take to ensure the safety of your unit:

Turn off Your Electricity

Make sure that you and other family members know where to access your electric circuit breaker and/or your AC Isolator.  AC Isolators are normally mounted on the wall next to your outdoor unit.   You’ll also want to understand how to shut off the electricity in your home in the case of violent storms. Label your circuit breakers so that you can tell which breakers are connected to which major appliances including your heating, ventilation, and air conditioning (HVAC).

Turning off the breaker/isolating your air conditioning units will help you protect the systems from electrical surges and damages.

Pre-Cool Your Home

If you feel like your power may go out during a storm, make sure to cool your house in advance so that you will be comfortable until the power comes back. Set your thermostat to a temperature that is cooler than usual, close your curtains and blinds, and keep all doors and windows shut to keep the cool air inside.

Ensure You Have Adequate Insurance 

Some basic homeowners insurance will cover storm or cyclone damage. If you live in an area that is vulnerable to flooding or cyclones, ensure that you have suitable coverage for these situations.  Having additional coverage will give you peace of mind that your expensive equipment is covered and can be easily replaced if need be.

Prepare Your Yard

This may seem like an odd measure, but making sure that all your trees are trimmed and yard items removed can help protect your air conditioning unit and your home as well. Remove anything that can be blown around and lead to damage in the case of high winds.

Cover the Condenser

In most situations, covering your air conditioning condenser outside is a bad idea. This is because the condenser needs free air circulation to operate efficiently. However, during a storm, temporarily placing a tarp over the condenser can help protect it from flying debris. Make sure to turn the system off before doing this.

When small items such as branches and leaves get caught inside the condenser, it can damage the motor and lead to other equipment malfunctions.

Check for Damage After Storm

Making sure to check for damage to your system before you turn your air back on is one of the most important steps. If flooding or debris has caused damage to the unit, turning the system back on could make the problem worse.

Strong storm winds can also cause disconnections within the AC unit. You will want to turn your AC unit on as soon as it seems safe. This will prevent mould and mildew from settling in.

Contact a Professional

The safest approach is to have an HVAC professional regularly come out to check your air conditioning system to make sure it is in good order. If you suffer storm damage, do not turn your unit back on until you have your unit inspected by an air conditioning professional.

Some storm damage may not be apparent and can cause more damage after the storm has passed. A thorough professional inspection will ensure that the unit is safe to turn on and will continue to work efficiently in the future.

Does Your AC Smell Strange? Funny AC Smells and What They Mean

Turning on your air conditioning unit may seem like the perfect complement to a hot and sweaty day– that is, until you start noticing a funky smell fill the room. In the sunny and sometimes humid city of Cairns, such smells can mean going through a dreadful experience of either bearing the stench, or enduring the heat.

It is not a problem to be shrugged off, either, as these odors are clues to underlying issues your air conditioning system might need help with. Not only that, but these odors can be toxic to your health.

Thankfully, these “odor clues” are distinct and familiar smells that can lead you straight to the root of the problem. Ready to see the kinds of smells to watch out for? If so, read on.

Mildew / Mould / Dirty Socks

If your nose picks up the scent of mildew, mould, or even dirty socks whenever you power up your AC, it is very likely that the moisture inside your AC system has pooled up enough to cultivate mould and other microbes, all of which are not good for your lungs when inhaled. These microbes can grow anywhere, from your AC’s filters to its ducts and/or drain pans. In order to thoroughly clean through your AC system, it is best to call professionals who know the ins and outs of any given air conditioning unit.

Rotten Eggs / Trash

Believe it or not, your AC unit is an attractive home to little critters such as birds, insects, and lizards. Some of them, however, don’t make it out alive, eventually causing your AC to emit an odor similar to the scent of rotten eggs and trash. To reduce the odds of having the stench stick to any clothes and furniture, turn off the AC and open the windows to clear out the smell. It is best to call aircon servicing specialists to handle removing the unfortunate animals from inside your AC system. Also calling pest control specialists and inquiring about pest-proofing can help prevent this from happening in the future.


Does it smell like something is burning? Turn off your air conditioning immediately as this is a huge cause for alarm.

Your AC unit is made up of electrical wires and components, so chances are, something inside your AC might have overheated, short-circuited, or even caught fire. To stay on the safe side, call your nearest fire department. Once the scent dies down, call a professional aircon servicing team to investigate the insides of your system.

Do I Need a New Air Conditioner?

Your air conditioning system won’t last forever. At some point, you will need to replace the system for the sake of efficiency, renovations, or even due to outright failure of the unit. It’s important to realize when your air conditioner is near the end of its useful life before it completely breaks down and you’re left sweating in the heat.

Let’s take a look at some telltale signs your air conditioning system needs replacing:

Signs You Need A New Air Conditioner

There are some rather clear signs that your air conditioning is not functioning the way it should. In some cases, only a minor fix is needed. Other times, the unit as a whole needs to be replaced. Here are the signs to look for when deciding if you need a new air conditioner.

1. It’s Producing Strange Sounds

A fully functional air conditioning system should operate in almost complete silence. If you’re familiar with your unit, you’ll recognize the little sounds it makes as it cycles. These sounds will be a regular part of your air conditioning’s life.

It’s when you hear other noises different from these normal sounds that you need to inspect the unit. Small noise changes could simply be the sign of something that needs repair. For example, there could be a loose part inside the unit, the fan may not be working properly, or an internal component could be clogged with dirt.

However, if the noise is more out of the ordinary such as grinding, rattling, screeching, ticking, or buzzing, this can indicate a serious problem that means you need to replace the unit.

2. Leaking And Excess Moisture

For some air conditioners, a small amount of condensation or water dripping on the unit is normal. However, your air conditioning unit should stay dry when it’s being used and when it’s idle. If you notice a leak, a sudden increase in condensation, or moisture inside the house, it may be time to look for a replacement.

Electrical components and water do not go well together. As such, you should have the unit inspected by a professional air conditioning technician straight away. Units can spring refrigerant leaks, which should only ever be handled by a professional due to their potential health and safety risks. Your air conditioning repair technician will locate the source of the leak and determine if a new unit is the best choice or if a simple repair will do the trick.

3. Reduced Airflow

Check your air conditioner to see if there is little or no cool air coming out of the vents. A noticeable decrease in airflow could be a sign that your air conditioner’s compressor is near the end of its life.

If your thermostat is set to a moderate temperature and your home is still too warm, then your air conditioning unit is not working at its intended level. Check the filters first to see if they need to be replaced. If they aren’t to blame, however, your unit may have reached the end of it’s efficient life, and it may well be time to replace it.

4. Fluctuating Temperatures

A common problem with an older air conditioning unit is that it simply won’t cool or heat. It may still produce good air levels, but the air isn’t coming at the temperature it should based on the settings. You may occasionally experience warm air on a cool setting (a cause for concern), but if your unit stops producing any cool air altogether, it’s time to call in a professional to have a look. The same applies to a lack of heating. In some cases, the problem may be low refrigerant levels. However, the presence of warm air when the system is set for cooling can indicate a big problem such as a damaged compressor.

You’ll also want to look out for inconsistent temperatures. Your air conditioner is designed to provide consistent air temperatures at the settings you select. When certain areas become cold zones, and others don’t get any cool air at all, your air conditioning unit may need to be replaced. If your system is producing inconsistent or warm air, inspect the filters, condensation drains, valves, and coils for airflow obstructions.

5. Your Energy Bills Are Increasing

Even when your air conditioning seems to be functioning fine, one of the clearest signs there could be a serious problem is your energy bill. If your bill has suddenly increased for no apparent reason, there could be a problem with your unit.

Conduct an energy audit and consider if there are other factors that could be responsible for the increase. If it appears that your air conditioning is the reason behind a spike in energy costs you will want to determine why it is losing efficiency.

In some cases, it could be overworking. Reduced cooling capacity will raise energy costs as your unit struggles to maintain your desired temperature. You can try replacing the filters, cleaning the air vents, and checking for knots in the condensing coil. For those with older homes with older AC units, it could also be the case that your unit is near the end of its service life and simply lacks the efficiency to cool your home properly as a result. 

6. Strange Smells

Like odd noises, unusual smells can be a sign your air conditioning or ducts need replacing. Unpleasant smells can mean that the unit’s insulation is damaged or that the ductwork is moldy. Mold, mildew, and dirt inside your unit can circulate contaminated air throughout your home and cause serious health issues for you and your family.

Strange smells could simply be the result of a filter that needs replacing. Check the filters first but if the smell persists it may be time to replace the unit or your ducting.

7. It Need Frequent Repairs

Your air conditioning unit should be serviced once a year to ensure it’s in good condition. You may need an extra repair here or there but if your unit is in constant need of mending you will likely be better off replacing it with a  new one. This is especially true if the unit needs a major repair after its warranty expires. Opting for a new air conditioner is often more cost-efficient than expensive repairs on an older unit.

8. The Unit Is Old

In Cairns air conditioning is a must, especially in the hotter months. The average air conditioning unit lasts between 7 and 10 years, depending on its usage and environmental conditions, and the average warranty from major manufacturers is only 5 years. There have been a lot of advancements in technology in the past decade, so if you’re using an older model you’re missing out on some useful features and incredible energy efficiency improvements. Newer models are built to be much more energy-efficient and come in more compact styles as well. If you have an older unit, consider making an upgrade to take advantage of these benefits. It may end up saving you far more than the cost of the unit.
