  • I can only say amazing things tonight about Mercury Heating & Air Conditioning

    “I can only say amazing things tonight about Mercury Heating & Air Conditioning (specifically about Ian). It had been over a month of our air conditioning unit not functioning correctly, and we had used our home warranty company to find a contractor to fix the problem. That contractor (and his employees) came to our house five times unsuccessfully trying to fix issues that were not the problem and caused other issues with their "fixes". We were fairly fed up. We decided to call a contractor on our own dime to fix the issue. Ian, from Mercury, came over tonight (on a Sunday, no less) and listened to what others had done, and was able to find three problems in less than a half an hour. He also was transparent with my husband and me about what the key issues were and proceeded to help fix the problem. In a few hours, our house had finally cooled down! We have a young infant at home, which was causing concern with the nearby air quality worsening and no way to cool the house down. This company is honest and its staff - hardworking and most importantly understands how an HVAC system works! I would highly recommend them to family and friends or anyone who is looking for honest HVAC technicians (not trying to sell you on random products you don't need)!”

    “EXCEPTIONAL!!! I called Mercury because my 20 year old air-conditioner stopped running. I spoke with Jason to schedule an appointment. He was professional and very accommodating, scheduling around my work schedule. Ian was able to come out the next day. He was honest (which is hard to find in this industry) and took the time to take pictures of what needed to be replaced and worked on. He spent over an hour, inspecting both my furnace and air-conditioner, and taking the time to explain how the parts worked, what the pictures meant and what my options were. I was pleasantly surprised at how quickly the parts were ordered and Ian replaced them the next day! Ian came to my home after working a 12 hour day on another job, and still took the time to show me and explain the replacement parts he installed. Above and beyond - EXCEPTIONAL service! I highly recommend Mercury to everyone.”

  • Lifesavers!

    “Lifesavers! AC went out during triple digit week... These guys came over, assessed the situation and gave me a couple options on how to fix - A) probably temporarily, or B) replace completely. After weighing the options, and a couple different proposals, we settled on a full replacement. One and done! They even went the extra mile and sealed up some open areas that were letting out air I had no idea about. New unit is 10000 times more effective, and they got it done super quick! Couldn't have asked for more, great job guys!”

  • I really can't thank him enough for all his work!

    “So my furnace went down a few days ago. The timing was bad as the temperature dropped well below 40 at night in my area. I found Mercury on Yelp and they were the only one who had availabilities that worked for me. Ian followed up quickly after I made my appointment through their website and confirmed the schedule. He showed up on time and started the diagnosis immediately. Within minutes, he pinpointed the issue with my furnace and patiently explained to me why the system stopped working. We walked through a few options and Ian provided me with pros and cons for each one in details so I have enough knowledge to make my decision. After I decided to go with Ian for the repair, the whole process was a breeze. Parts came quickly and the repair work was almost a piece of art. Within hours I had my furnace back and running in a much better condition! Ian patiently tweaked around the system and made sure every part is working correctly. I really can't thank him enough for all his work!”

  • Happy with his services.

    “I've been having cooling problems so I called some one on yelp whose ratings are good. He claimed my ducting was bad and tried to do a used-car salesman act on me, trying to pressure me to buy his services for a mere $7000 because he would give me a good deal by cutting out his employer, wink, wink. I called Mercury Heating and Air Conditioning. Ian confirmed that my ducting had problems, but that it wasn't the main one. Freon was leaking, there was years worth of dust in the coils of the AC (he snaked a camera in to show this). He seemed quite trustworthy, and fixed a lot of my other problems for $650 (we bought a 45-year-old house recently). Happy with his services.”
