WHEN SHOULD I REPAIR OR REPLACE MY COMMERCIAL HVAC?
Sometimes, wasting money trying to repair your dying HVAC just isn’t worth it. You’re usually better off replacing your unit completely when your unit is nearing 10 years old. Most commercial HVAC units only last about 10–15 years. But your commercial HVAC might need to be replaced sooner than that if:
- Your current system is over or undersized: Improperly sized units suffer a lot of stress, which can lead to early failure. Unfortunately, this is a common problem for commercial units because similarly sized spaces may need different size HVAC units depending on how the space will be used.
- You have leaky ductwork: Leaks in the ductwork reduce the lifespan of your HVAC. Since some of the conditioned air is escaping out of the duct leaks, your HVAC will work harder to cool the space, which means more wear and tear on the unit.
- You haven’t scheduled regular maintenance: HVAC units that have been taken care of with annual tune-ups and regular air filter changes will last longer than those that haven’t.

The equipments manufacturer warranty has expired. If your manufacturer warranty has expired on your commercial HVAC, repairs on the unit will be much more expensive. If a pricey part dies, like the compressor, you might just be better off putting that money toward a brand new unit.
The HVAC doesn’t heat or cool well anymore. If your unit doesn’t keep your employees or customers comfortable anymore, it might be nearing the end of its life. If this is the case, you’re likely better off getting a new, efficient unit that will provide higher levels of comfort and lower utility bills.
Your unit needs frequent, expensive repairs. Here’s a good rule of thumb: If multiplying the cost to repair your HVAC by the age of your unit is more than the cost of a new unit, consider replacing the unit altogether.
Your AC uses R-22 refrigerant and is 8+ years old. The older your AC is, the more prone it is to refrigerant leaks. Leaks are especially expensive if your unit uses R-22 refrigerant (also known as Freon™), as R-22 is no longer being produced in the U.S. For context, it could cost up to $1,350+ to recharge a 12-ton commercial AC with R-22.
