Enviro Heating & Air Conditioning, Inc. Customer, 1 of 199
"I like that they are local. It's a husband and wife who work together and the wife takes care of everything, answers the phone and distributes the workers. The husband fixed a furnace a couple of years ago and coaches little league, which is a plus. He stopped on his way home on the weekend and fixed it when no one else would. I'm going to be a lifelong customer as long as they are in business. They are a local, family run business and they explain to me everything that they are doing. If they adjust the jets, they tell me, show me everything and let me watch." - David M.

Heating and Air Experts LLC Customer, 1 of 97
"I would say they were knowledgeable and got the job done. I spent a great deal of money on it, but it is the original air conditioner for the house 89-90, not an inexpensive fix. At a minimum, if they need that type of work, give them a call. I am happy with the work they did and their professionalism. They were nice young men and knew what they were doing." - June W.

Elevated Comfort Customer, 1 of 89
"The sales person should be more thorough with the contract. Apparently, the outage with our air conditioning was 35 voltage, but our power was only 30 voltage, so our air conditioning would go out due to not getting enough power through. They should be more thorough about it. The technician is very thorough, very nice and they know a lot." - Hannah B.
