"The company was easily reachable on a Friday evening and arrived to repair my heat pump (dead capacitor) promptly on Saturday morning. The technician, Albert, was knowledgeable and courteous, and the price was very reasonable. I'll be using Magna Tech for all my HVAC work in the future."

"I hired Air Quality HVAC to replace my aging HVAC system and I had a fantastic experience with them from start to finish. Amar was patient in answering all of my questions along with providing pros and cons for the various options. He assessed the situation whilst giving me comprehensive and thorough advice regarding the best way to proceed. Amar and his team arrived and began their work at the scheduled time. They took great precautions not to damage anything by placing cardboard over the flooring and they moved carefully throughout the home. They worked efficiently and effectively without rushing the job. When finished, Amar and his team did an excellent job cleaning up ensuring that no mess was left behind. If you're looking for service that is courteous, fair, and reasonably priced, then look no further than Air Quality HVAC. They provided a quality of service beyond my expectations, and I sincerely appreciate their commitment to honesty and professionalism."

"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"Team did a great job, and didn’t try to upsell me. They diagnosed and replaced the leaking pipe - a competitor tried to use the leak as an excuse to sell me on replacing the entire boiler as the only way forward. Appreciated JDL’s focus on addressing the issue at hand. They also tested and confirmed existing boiler had years of life left in it."

"SwiftPro did a fantastic job with our AC system replacement. Rich came out and gave us an estimate and did a great job explaining all the options. We made a decision and they arrived two days later and we have heat and air in our second floor area again. The techs that came out took a lot of pride in their work and it showed. Great install!! Highly recommend SwiftPro!!"

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"I had an absolutely terrible experience with McRae Air Conditioning and Heating. I purchased a home equipped with their HVAC system, and within just five months, the heat stopped working—right in the middle of winter during a snowstorm. My home was freezing at 50°F, so I called for service, which should have been covered under warranty. I scheduled an appointment, and the technician, after being several hours late, went to the wrong address, left a sticker on someone else’s door, and left without even trying to contact me. When I called back, the customer service rep was rude, dismissive, and completely unhelpful. He initially told me the technician was on the way and just 12 miles away—but after another hour of waiting, I called again only to be told that the technician had already “been to my house 2 hours ago” (the wrong one) and left a note. If the rep actually wanted to help, he would have told me this during my first call instead of wasting my time and leaving me sitting in the cold. Not once did the technician call me to confirm the address or check in after knocking on the wrong door. When I expressed my frustration, the rep rudely dismissed my concerns, saying, “Well, I had nothing to do with that,” and then interrupted me with, “Do you still want to rebook or not?” as if I had to stop talking or risk not getting another appointment. This was an emergency call in the middle of winter, and McRae handled it in the most unprofessional, careless, and disappointing way possible. If you’re considering using them for HVAC service, do yourself a favor and go with another company. I’ll update this review after the (hopefully successful) service call and speaking to the manager who was not there at 4 pm on a Wednesday."
