    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!!

    Fantastic Work. Took care of our HVAC needs on multiple occasions. Always prompt and professional. Entire team from phone call to install is on the ball.
    Would recommend them to anyone.

    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.

    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 Jim Sanders ★★★★★ in the last week
    Arrived early, explained my choices well, finished the job quickly. Good to have the A/C back!
  • Avatar Neal B ★★★★★ in the last week
    Service was fast and excellent. New air conditioner works great.
    Used Unionville Heating and Air Conditioning for years and would not hesitate to recommend them
  • Avatar John Frotten ★★★★★ a week 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.

    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!

    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.
  • Avatar Susan Munroe ★★★★★ a month ago
    All of the above plus I appreciated all the extra precautions, mask, gloves etc during this challenging time. Dave was very patient in going over everything and answering my questions. Communication from Michele prior to appointment was … More also excellent.
  • Avatar Gary Brewin ★★★★★ in the last week
    Todd is extremely professional. He fixed our furnace with no issues. Extremely knowledgeable. I can’t recommend this company enough.
  • Avatar Niran Balachandran ★★★★★ 2 months ago
    My furnace had stopped working and I called Unionville Heating and Air Conditioning for help. I quickly got through to John, the owner of the company. He spent the next hour troubleshooting the problem with me. A technician (Dave) ended … More up coming to my home. Rather than overselling me on unnecessary repairs, he quickly found the problem with my furnace and got me up and running again. I am so grateful for John and Dave's help. Unionville Heating have always been responsive, informative and never try to sell you more than you actually need. If you want quality service, I wouldn't recommend anyone else. Thank you!
  • Avatar Eric Tappenden ★★★★★ 2 months ago
    We have been served by Unionville Heating & Air Conditioning the past few years - first fixing our old furnace & then putting in a new HVAC system last summer. The price was good so I felt no need to shop around. And their service … More since has been superb. Too many good stories to share in a review but I recommend them highly!
  • Avatar Tony Chieffallo ★★★★★ 2 months ago
    I was very impressed with the professionalism and honestly provided through Unionville Heating & Air. My technician was Eric Ranchigoda and he was very knowledgeable about fixing my heating system. I had another company come in before … More Unionville Heating & Air (won't mention any names) and they told me my whole system was shot and that I needed a new furnace. I called Unionville for a second opinion and I was immediately directed to the owner, John, who told me otherwise. They then sent Eric to my home on one of the coldest days of the year and he fixed my furnace within a day. If you're ever told you need a new furnace, be sure to call Unionville Heating & Air first for an honest opinion. Thank you once again to Eric and the company for helping me solve my furnace issue.
  • Avatar John St.Germain ★★★★★ 2 months ago
    Even as the owner of this company my staff never ceases to amaze me with their politeness efficiency and dedication. I am not alone, as all our customers are treated as if they were the owners and that’s why they keep coming back to our … More company.
    Great work and logistics from our office staff to our installers and to our service team led by Eric , our service supervisor overseeing the problem at our home over the weekend.
    Thx to all, well done.
