"All I can say is there is no need to go to any other HVAC company! My wife and I have hired almost every company on the North Shore, and I can tell NOBODY delivers better on price, maintenance, and the quality of the install than All-Temp Heating & Air!"

"I’m extremely satisfied with Regional. We had three sump pumps that needed to be replaced (primary, secondary, and water powered backup). The quote was very reasonable, and they were able to do the work shortly after their initial visit. They replaced everything with Liberty pumps. Justin and Erich did the work and they were very professional. We had them quote out a couple of other items (replacing water heater, etc) and those quotes were also very reasonable. I will definitely hire them for future jobs."

"The only time they had available was in the evening so I had to pay double the amount or a regular service call. I agreed to that because the temperature in my house probably around 40°. They gave me a timeframe for service from 5 PM to 9 PM and a service person would call when on their way. I was thrilled that Brett called me at before 5pm. Brett was very professional and thorough. He walked me through what needed to be fixed and prices. Within less than 35,minutes he replaced my broken igniter and answered questions about my desire to replace an 18 year old furnace."

"My husband carefully spelled out his name and our address over the phone, but the office still got both wrong. But besides that, the service tech arrived early after calling us in advance (much appreciated), found that the drain trap was plugged which prevented the unit from moving into the second stage of the heating process, and he cleared it. We're confident that the problem was fixed, and we're pleased with the work he had done. Jim was personable, knowledgeable, and helpful. But for the 20 minutes he was here, and the limited scope of the work that we could see that he had done, we feel that the charge for our drain line flush of $288 was pretty high. We didn't get quotes from other HVAC companies, and we trusted AWE based on Angie's List's reviews, but on reflection, it seems pricey to us. We will nevertheless call them for annual servicing because they are reliable."

"We had a great experience with Four Seasons Heating & Air Conditioning during our recent replacement of our furnace and AC unit. They were very professional and completed the job on time and answered all of my questions. Would recommend them for our Heating, Air Conditioning, Plumbing and Electrical needs."

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."
