    I called Unionville Heating to have our air conditioner repaired (it just stopped working). I mentioned to the person who took my call that my mother was 83, and if it was possible to have someone come out today to take a look because … More I didn’t want her in a home without air conditioning.I was advised that “Dillion” would be out to our home between 2pm - 4pm.At 1:57 the truck pulled up, and within 30 minutes Dillion assessed and fixed the issue.He advised that more then likely we would need a new unit and then gave me details on what that entailed.Dillion was such a well informed, professional technician that I will most likely be purchasing my unit from Unionville Heating.I received wonderful service from your company and would happily recommend them to any of my neighbors.

    Very impressive business. Exceptional work and customer service. Can't say enough about the staff from the technician Todd who diagnosed the problem with the old A/C unit to the installers who promptly came to install the new unit. … More Everyone who came into my home was prompt, courteous and followed proper Covid 19 procedures. The owner even called to make sure I was satisfied with the work performed after the job was completed. I highly recommend this company for all your AC and Heating requirements. Thank you again to the entire staff that was able to get my new AC installed and working efficiently...greatly appreciated!!

    What can I say about Unionville Heating & Air Conditioning, from start to finish, all services were taken care of with the utmost professionalism, and attention to detail.
    I'm a contractor myself so I feel I know what to expect
    … More as far as new installation of equipment entails. And they have definitely delivered. We had our furnace, and A/C removed and replaced with new, efficient equipment.
    The install was super clean and professional, and technicians Dave, Ryan, and Liam were very efficient, friendly, and did a great job. Service tech Todd took his time to see what could be done with our old A/C in the meantime until our install date came a few days later.
    Owner, John was very responsive, and happy to help, and take time to answer any questions I had regarding the process. Even Michele in the office took her time to answer questions and was a pleasure to speak with over the phone.
    Special shout out to Dave, thanks for taking the time. Highly recommended HVAC company.

    This is the second time I have called Unionville and both times the experience has been fantastic. I always confident that I am getting the best service and the best advise. Honestly, having an HVAC breakdown can leave you feeling vulnerable...these … More guys put you at ease and aren't looking to take advantage. Highly recommend.

    Excellent customer service! I recently purchased a new air conditioner from Unionville Heating and Air Conditioning, which will be installed next week. In the meantime, our current air conditioner (which was NOT purchased from Unionville … More Heating and Air Conditioning) has failed 3 times. After our purchase, they said they would keep our current system running at no charge, which they have. Each time I’ve called for service, they have responded quickly and the service technicians are all friendly, highly skilled and knowledgeable in their field. Every person I’ve dealt with has been professional and beyond helpful. From John (the owner), to the office staff, to their technicians. In the past, I have called Unionville Heating and Air Conditioning for furnace and fireplace (2 fireplaces) maintenance, and was very impressed and pleased with this service as well. I highly recommend this company for any of your heating and cooling needs!

    Originally brought them in for a repair based on great reviews. The unit needed a $500 repair, but since it was a 30+ year old unit, they offered to apply the repair costs to the cost of a new unit. I took them up on it. They were great … More with communication, and, in these COVIDy times were very safe and clean. Highly recommend.

    I called when our air conditioning stopped working, and a repair person came within 3 hours. He had it working in half and hour and was friendly. He also maintained social distancing and wore a mask and gloves. Excellent experience with … More this company, thank you!

  • Avatar John Frotten ★★★★★ 4 months ago
    My air conditioner stopped working last week, I have been a long time customer of Unionville Heating and Air Conditioning, they sent a serviceman who gave me the bad diagnoses, unit has to be replaced. I called John St.Germain and explained … More that I am a senior living on a pension and what can we do to help me get my unit replaced. He made several suggestions and we arrived at an agreement that we could both live with. His crew arrived on time, replaced the unit and now i am cool again. They were professional and cleaned up after themselves. This is truly a company that CARES, thank you to all your staff.
  • Avatar James Rankin ★★★★★ 5 months ago
    Great visit from my tech. He was courteous, expedient, and did a great job. My only complaint is that the furnace filter is twice the price for the part as I can purchase from Amazon, and have delivered to my door for free. In the future, … More I'll obtain my own filters.
