"Excellent! They're the best if you want something done with your plumbing and heating."

"Woke up on the coldest day of winter (so far) to find our furnace had stopped working overnight. called John at about 8:30 a.m., and he had a team of technicians at our home within about two hours. He even stopped out himself to check in, drop off some parts, and talk to me about my long-term needs for a new furnace and A/C unit. The team worked fast, and the charge for the work was even less than they estimated when they'd arrived. This is the second time we've called John's folks for heating or cooling service, and we'll absolutely use and recommend them again."

"Had wade install a Mitsubishi Mini Split with 4 ceiling units on the 2nd floor to assist with heating and cooling issues. The whole process was easy from beginning to end with very clear and quick communication. Also had them repair an existing system at the same time that was quick, hassle free and got me fixed up properly. I want to especially thank Lonnie, Mr Wade and the Installers for their expertise and professionalism along the way. I am extremely satisfied with the Mitsubishi units that were installed and would highly recommend their services!!!"

"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."

"I would recommend Frank for any heating and A/C work needing done."

"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."

"They did a great job and I recommended them to my company for their HVAC needs."

"I think they are on Angie's List and we feel very strongly about them. I like them specifically because of their knowledge set. Very few people know how to service residential boilers. Gravener is very good a at that. I have recommended them.  I am on the community county council and I have brought them in to speak to the public. They are responsive and they know their craft very well. I did have one complaint from their job they did in 2014, but their service calls have been fantastic. They are prompt, pretty clean and they thoroughly check out the boiler to make sure it is safe. There are a fair number of safety controls on there that they are careful to make sure are operating properly. They are the only people I will call."

"Highest ratings and respect to Air Pure. Such a professional and competent installation. I am so happy with the service and my new furnace! A purely wonderful experience. Thank you Air Pure!"
