Best Heating & Air Conditioning / HVAC In Tewksbury

“Josh Greenleaf has been taking care of my plumbing needs for the last 8 years. He is an outstanding technician and a wonderful person. With every visit he takes a look around to see if he can proactively find any issues and has found many small things that could have turned more costly if not taken care of. I also use them for HVAC. Heritage has always been excellent to work with and I highly recommend them.“

“Excellent mechanic and great service. Stayed with us after hours to ensure we had heat on a bitterly cold night.“

“Coolair has installed 2 new furnaces and air conditioning units over the years for the upstairs and downstairs in my house. I can them at anytime, day or night & my call is always answered. Most recently I called on a Friday night & Bill, the owner, came to resolve the problem. Coolair is a very responsive, caring company.“

“Long overdue for me to sing my praises. Wayne came to save the day today, and my entire family have been customers for I think 30+ years. Thank you“

“I cannot say enough good things about Excel. We were having an issue with our central air and had previously had it serviced 3 different times within a month by another HVAC company. They could not figure it out which was especially stressful during a heatwave with 2 small children in the home. Our neighbor recommended Excel and luckily they were able to fit us in. The service was top notch. They were professional, communicative, knowledgeable, friendly and on time. They explained the issue in detail and also explained what they did to fix it. Our unit is running better than ever. I HIGHLY recommend this company.“

“American Air was super responsive when we called and did a great job replacing a part to get us up and running again. I would highly recommend them.“

“Called franks for my elderly father in laws central ac unit not running. They came out within a day and had his system running great! I was concerned about the age of the unit and made them aware yet all they did was repair it instead of trying to sell him a new unit. Appreciate the honesty and transparency will be using you exclusively moving forward. Thanks!“
