Real reviews from AngiesList.com from satisfied customers:

"I was glad to find someone who communicates promptly and then arrived when scheduled.  He took the time to explain the inspection so that I now know what to watch for in my antiquated unit.  I'm not ready to replace it yet, but will call them when I am."

"They diagnosed problems with a 20+ year old furnace, and then gave me a very good price on a new furnace.  Very knowledgeable, and willing to go the extra mile."

"The technician arrived on time and within a couple of hours of my initial call.  I am a first time customer and am located approx. 20 miles from their office.  Service was extremely expeditious taking only around five minutes to troubleshoot and around 15 minutes to fix the problem.  After replacing a faulty contactor the technician conducted thorough air temperature tests to confirm the unit was working properly."

"They are proud of their customer satisfaction rating, and they should be.  If you haven't priced air systems lately, it can be a shock, but it helps to know that you are dealing with a company of integrity and that you are paying a fair price."
