It doesn’t matter whether you use oil or gas heat — Lennox Heating & Air Conditioning has a range of furnaces that will bring efficient warmth to your home. Our furnaces have AFUE ratings from 80% up to 99% which means that at least 80% or more of the fuel you pay for is actually converted into heat for your home.

Fast response to our furnace going out on a 20 degree day. Dennis was quick and knowledgeable and able to diagnose the issue quickly. Happy to recommend.

Integrity was easy to reach, they responded quickly with an appointment for service and the repair person was professional. They arrived on time and sent picture of the repairman. We have not used our AC yet because it has been cool since they were hear but we would highly recommend this company

Integrity Heating installed both my heating and AC unit. I am pleased with the responsive, professional service and quality of work. Aaron and Juan are experts in their field and conducted their job professionally. It is because of the quality of service that a humidifier was recently purchased and installed at our home. Kudos to the overall Integrity team!
