"We came home from an outing on a Sunday night and found our air conditioner not working. I found John Mullen on Angie's list and liked the reviews. I contacted John and he asked me about my schedule on Monday. He fit us in on Monday morning. I wasn't home but my wife was. She said that John was so nice that she assumed that he was a friend of mine. I told her that I never met him before. He fixed the air conditioner and I am relieved that it didn't cost us a ton and we avoided 85 degree heat with an air conditioner. I would use John again. He was dependable, came out with in 12 hours of being called, and my wife does not always comment on how nice someone is unless it is absolutely true. Thumbs up for John Mullen, I have just found a go to guy for everything!"

"I have dealt with Wade since 2006. in 2017 I had them replace a heating and cooling system. They are very knowledgeable, technicians / installers are great to work with. Their pricing is very fair and there service is reliable."

"In October the boiler that provides both heat and domestic hot water to my house expired and could not be repaired. Climatech and one other reputable company came immediately to determine my house's heating requirements and bid on a modern replacement boiler. Climatech was substantially less expensive and they were nice enough to juggle their installers' schedule so that I could get the new system installed ASAP as I had no heat or hot water for several weeks. The new system is much quieter than the old system, is more energy efficient, heats the house better and takes up much less space in my basement. This was an expensive project but I am very pleased with the value received and the service provided."

"The service guys were great. South Hills took the order, but the service guys admitted they had never worked on a pool heat pump in his 35 yrs. of servicing. He said he would do his best to figure the problem out. Two men worked for 2 hrs., but were unable to rectify the issue. They charged me the minimum of $109. The service guys were wonderful, but said there company should never have taken the order."
