It’s been with you for years and has served your family well. It’s kept you cool and comfortable through dinner discussions and TV binge-watching. It had your back during parties and holidays. But lately it hasn’t been performing as well. It makes strange noises and smells and doesn’t quite hit the mark on temperature. It’s even been through a few repairs. It’s probably time to let it go. Here are the biggest reasons to replace your system.


The average lifespan of an AC system is 10-15 years.  So, if yours is in that range and isn’t up to snuff, you should consider replacing it with a newer, more energy-efficient system. With heating and cooling costs accounting for about 44% of your utility costs, getting a more efficient system can really make a difference. Also, older systems sometimes use a coolant that’s been phased out, which can also be more expensive to replace. The newer systems use the right coolant, which will save you money when it needs to be replaced, too.

Noise and Dust

Constant dust in your home, even after cleaning could mean you have leaks in your ductwork. This can seriously reduce your system’s efficiency. If you’re also hearing excessive noises, your duct system may not be large enough for the size of your home or there’s a problem with the unit’s indoor coil.

Your AC expenses are going up

If your bills keep getting higher but you’re not using your AC any more than usual, or you’re having more and more repairs done, that’s a sign your system is becoming less and less efficient.

Inconsistent Comfort

When you’re not getting consistent cooling, chances are your system or your ductwork isn’t operating properly.

So, when it’s time for replacement, don’t feel so bad. AC systems don’t last forever. And you’ll be able to get some of the cost back by not having more repairs and by saving every month on your energy bill. Plus, your family will be a lot more comfortable. And if you want to say a few words in honor of your old system as the truck pulls away, well, that’s okay, too.
