    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.

    We are in the middle of a heatwave and our AC unit broke. We need to replace the unit. While we are waiting for the unit to arrive we are slowing melting in our house. Everyone is hot and angry and I have begun to hallucinate and cry … More from the heat. Dillon and the staff at Unionville Heating have come out to put a temporary motor in our old unit to get that going until the new unit arrives. They went above and beyond! I am now going to go to bed and sleep beautifully. #Dillonrocks

    Our furnace died in the dead of winter. With a new baby in the house we were in need of a new furnace and quickly. Unionville Heating installed a new furnace in our home and had it up and running without any problems. They were clean, … More friendly and happy to answer any questions I had. I would recommend this company and will have them back for our annual maintenance.

    Unionville has been our hvac maintenance contractor ever since we moved in 9 years ago and have always provided great service. Recently our furnace was acting up and being 20 years old, the recommendation was to replace the furnace. … More
    After a bit of negotiation, Unionville offered some discounts and gave us a pretty decent price on a Goodman 96% high efficiency furnace. The install was scheduled for a Monday, however on Thursday night the furnace gave out and we had no heat. At 10pm we sent an email to them wondering if the install could happen on the next day, Friday, not expecting a response till the morning. Within half an hour the owner, John St. Germain, replied saying they would make the next morning work. The next morning three technicians arrived on time and replaced the furnace in three hours.
    The Goodman furnace is working great and the house is nice and toasty. This was the coldest days of the winter and I'm sure they were quite busy so to make this happen on such short notice was impressive and really appreciated.
    We found everyone we've dealt with at Unionville to be knowledgeable, professional, polite, punctual and friendly. We plan on continuing to deal with them on all our hvac needs and highly recommend them.
    Gordon and Christina

    Unionville Heating & A/C installed our furnace and a/c mid-September. The Goodman A/C was amazing! The house was so comfortable and the air conditioner was super quiet — I could stand beside it and have a conversation, in comfort, … More with my neighbour.
    I also have to commend the gentleman that looks after fireplace maintenance. Because of the age of our Napoleon gas fireplace, there, apparently, is not much that can be done to improve its appearance, but, this young man improved the flame's appearance and cleaned up the surrounding insert. He did a superb job!
    The furnace had been a little more complex as we have been plagued with one very cold room ever since we moved in 17 years ago. We have just finished experiencing our first period of below zero temperatures this winter and that caused me to call Unionville Heating with my observations. Within 24 hours, Dave was at our door to rebalanced our system. This afternoon, that cold room reached 71°F for the first time ever — and 72 the morning after!
    I highly recommend this company. They are informed; they are responsive; they cannot do enough to ensure we are happy — they are the best. Our thanks to each of you working with Unionville Heating & Air Conditioning!

    Had a central humidifier installed. Guys did a great job. Were quick, courteous and professional. They even went as far as to clean up the bad wiring job I did for my smart thermostat. After the install when I had some issues with water … More pressure they were here within 12 h of me notifying to fix my issue. Highly recommended.

    We began working with the owner, John St. Germain, in early December 2019 when we were in the middle of kitchen renovations that included changes to heating supply and air return ducts. John was very responsive and professional in his approach … More and it became clear that he would do the work in a manner that he himself would be happy with – he suggested that if we agreed to work with him, that we should be ready to be impressed. I am not easily impressed, especially these days.
    It did not take long for him to come by and assess the situation, make recommendations and to provide a quotation the services – we tried for weeks to get another HVAC company to come by and provide a quotation. John looked at the big picture and used his experience to suggest some aspects that I had been thinking about but never felt that I could trust anyone to actually do it. The pricing was reasonable and we agreed quickly to move forward. We have an understanding that some of the work will have to be completed over the next few months as our renovation work proceeds. Once we started, the work that could be done was completed quickly and professionally. I have to admit, that I was impressed with John and his team – I was pleasantly surprised.
    The main things that come to mind about this recent experience with John and his team are:
    - Demonstrated an attitude of professionalism: a desire to understand the problem(s) and assess what solution makes the most sense
    - Set our expectations for the quality of the products and workmanship
    - Set our expectations for the schedule – the work was done with urgency (installation was 90% completed within 10 days of 1st contact) but without sacrificing quality
    - Work ethic demands work is done the right way – not juts the quick and dirty – and to be responsive to our needs
    - Exceeded our expectations for the schedule and the quality of work- I could trust this company to deliver on their promises
    We know this professional attitude will continue as we continue the work – my expectations continue to be high and I anticipate John’s team of professionals will continue to impress me as we continue to work together.

    We needed to replace a 17 year old water heater that just wasn't doing the job anymore (it wasn't an emergency). So I called Unionville Heating & Air Conditioning and two days later a replacement was installed quickly and … More efficiently. Tyler and Ryan showed up on time and their work was efficient and tidy. We are very pleased.
    This is a very professional company that provides great service at a very fair price.
    Thanks to John, Michele, Dave, Tyler and Ryan.
