AC Replacement Tips:

Our friends at Lennox shared this information on when is a good time to replace your air conditioning unit.


Is it time to replace your home heating and cooling system? Read our comfort Q&A below to see if it’s time to take the leap:

How old is your system?

The U.S. Environmental Protection Agency suggests replacing your air conditioner or heat pump if it’s more than 12 years old, and your furnace or boiler if it’s more than 15 years old. New units—especially ENERGY STAR® qualified models—have much higher efficiency levels to help lower your utility bills, and are more reliable than older systems.

Systems more than 10 years old use a lot more fuel than newer models. Review the SEER (efficiency) rating of your existing system and compare to newer models. The higher the SEER, the higher the savings you can expect. Lennox offers models rated up to 21 SEER.

How high are your repair bills?

Frequent repairs costing hundreds of dollars mean your service costs can soon exceed the cost of a new system.

Is your home uncomfortable?

If the rooms in your home are too hot or too cold, your current system may be too large or too small, or the system may have been poorly installed. Talk to a contractor about performing a load calculation to be sure.

Is humidity, mold or dust a problem?

A dehumidification system can help remove moisture than can damage both your home and your health. Adding a germicidal light can help to eliminate contaminants at the source, keeping them from recirculating throughout your home. Replacing HVAC filters once a month also helps to keep dust under control.

Does your home score below five on the Home Energy yardstick?

See where you score on ENERGY STAR’s Home Energy yardstick versus other homeowners. If you’re using more energy at home than most Americans, then you’re probably paying more on energy bills than you need to.
