Repair or Replace your AC unit – 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.
