Best heating and air conditioning pros near Renfrew, PA

"Would absolutely recommend John Mullen and his company. From the first time I called John he was very responsive and professional. I had called multiple other HVAC companies to install a vent through a brick chimney and were having trouble finding someone who would even come take a look to see if they could tackle the project. John didn't hesitate and came out and talked to us to find the right solution. Once we were ready for the job we were able to schedule him within about two weeks and he called the day of to see if they could come a bit earlier than planned. I truly appreciate the quick and professional communication throughout the whole process. The guys that came with him to do the work were also professional and they got the job done quickly. The price we paid was very reasonable for the length of time they spent and the difficult job of drilling out through brick."

"A great company, from the estimate to the install they were on time, informative and very professional. I really think I could not have found a better group of professionals to replace my current heat pump and air handler. Kudos to this company, I highly recommend you give them a shot at your HVAC needs. If their service is as punctual and professional as they have been for the install, I'm not sure you could find a better fit. Thank you Air Systems Mechanical and please say thank you to your team of guys for me who installed my system, they were outstanding! I found my go too for all my HVAC needs."

"They installed our HVAC system two years ago and they service it every 6 months. We have the furnace checked in the winter and the air conditioner checked in the spring. They are very reliable and professional and they do a great job."

"We've lived in our house for many years, but the air ducts and vents haven't been cleaned in some time. We had Bactronix clean, disinfect, deodorize, and protect our HVAC system, and we we were thrilled with the results. Bob and Frank were thorough, efficient, and professional throughout the process. We'd certainly recommend their services to others."

In the middle of July, when the thermometer is pushing past 100 degrees Fahrenheit, air conditioning isn't a luxury that's nice to have in Pittsburgh—it's an absolute necessity that you don't want to live without. It's obviously a disaster when your air conditioner grinds to a halt on the hottest day of the year. But it's also incredibly frustrating to deal with an AC unit that only "kind of" works and is struggling to get your house down to the temperature on your thermostat or control humidity levels. When you notice those types of annoying issues, it's necessary to get professional Pittsburgh air conditioner repair services before the problem worsens and you're left sweltering in an overheated house.

"Dave Hinchberger is a "pros pro!" Dave quickly and effectively analyzed my HVAC issue and then professional fixed my problem. Dave's diagnostic skills allowed him to analyze and fix my HVAC problem without "being a parts changer" as it seems most repairmen are that I have experienced. I cannot rate him high enough. Par Excellence service!!"
