  • Your company delivers the best service of any HVAC company I have ever dealt with.  I will never go elsewhere and will highly recommend you to anyone who asks.  Thanks so much.

  • Hi John - I've been down with a flu bug so I'm a little late contacting you. Just wanted to say thanks to your team for coming out last week and installing the complimentary air cleaner on my daughter's (Erin Lane) furnace. It was a great gesture on your part and truly reflects the company that I've known and trusted all these years. All the best to you and your staff.

  • It is difficult to compare. How often does one replace a furnace?  We did not shop.  This seemed more like a necessity than a choice.  Our decision was based on our history with you and service over the years and we have no reason to believe we made the wrong choice. Your install is team excellent!

  • I called Unionville Heating and Air for advice when another company servicing my furnace wasn't getting the job done: I had been patiently enduring 8 days without heat in the middle of February, despite repeat visits from the technician, and I was losing it! John not only took my call, he listened to my story, calmed me down and offered to contact the other company on my behalf to ensure they were going to get the job done properly. He called me back immediately to reassure me and encourage me to give the other company one more chance to correct the problem. He then gave me his cell number and told me to call if the problem wasn't solved by that evening. The next morning he called back to see if I had heat (yes, finally I did). I'm not even his customer, and yet John took the time to  listen to my concerns, advocated on my behalf, and checked in on me the next day. That kind of customer service is rare in these days, and you can be sure I'll give my future business to Unionville. Very impressive.

  • Friends at Unionville Heating & Air Conditioning:  Please accept my thanks for the excellent work & responsiveness from Craig!  We had Umberto fix our A/C and now with this furnace problem Craig did a great job!  You are real pros, and nice folks, too – you will have our loyalty in the future.

    Eric C. Tappenden Markham
  • Thank you for the service call. Umberto does a fine job of representing your company.  He is very thorough and diligent in his work ethics.   As well, he is very pleasant and polite to work with.  His tidiness is also well appreciated.

    Tom & Annette Atkinson Markham
  • Just writing to advise of excellent service from your company. It was just a furnace tune up/check up this time and installation of a humidifier last time. It was the same guy. Umberto Greco is the name on the invoice. Friendly, clean, efficient and very respectful and polite. He represented your company very well both times.  Even though you already have a good reputation with us, he has guaranteed future work. Not often I email a compliment, he just kinda stood out even though the jobs were small. Just thought you should know.

    Todd Stouffville
  • Thank you so much for your hard work installing our new furnace, air conditioner and HRV. You were so professional when you visited, taking the time to solve our downstairs heating problem by recommending we have a new duct installed. Dave, Brian and Craig were a pleasure to deal with. They kept us informed on how they were doing and completed the work to schedule in two days. I would recommend Unionville Heating to anyone, in fact I did speak to my neighbour but he is waiting to see how his system works out, having recently moved in. Please use us as a reference for anyone else in our community. Thank you all once again

  • We are greatly pleased with the product and the work provided, happy that you’ll come to Uxbridge too!

    Karin A. Uxbridge
  • Installer was very courteous and neat and installed the furnace the same day as ordered which was greatly appreciated.

    James K. Unionville
  • We got several quotes before Unionville Heating. What set them apart from the other vendors was the initial visit from John, the owner. Not only did he thoroughly examine the existing furnace and surrounding area (and discovered one of our vents disconnected) he took the time to walk through the entire house and ask us if we had any heating/cooling issues. John also invited us to the showroom (a brilliant concept) to see the equipment in an actual working installation.

    Richard & Mary P Markham
  • I really appreciated the quick turnaround from the time our furnace problems started to having the new furnace installed.

    David D Markham
  • I appreciated the speedy service and the air conditioner is working very well. Service personnel were very nice.

    Margaret R Scarborough
  • The installation was a first class job. The installers were polite and friendly. We won’t hesitate to recommend you to our friends.

    Susan & Neil. Markham
  • Thank you again John for your immediate attention to our heating needs. It is nice to know professional service is just a phone call away.

    Chris & Paula D. Unionville
  • I find that our Goodman air conditioner seems to be one of the quietest around.

    Les & Caroline W. Unionville
  • Your responsiveness to replacing our broken air conditioning unit within 48 hours, and on a heat wave, was fantastic! Thank you.

    Peter M Markham
  • We got your name on recommendation from a couple of people and are pleased to say we would recommend you to others.

    Ruthanne S. Stouffville
  • Your service people are always courteous and on time. Your receptionist, always pleasant as well. I am “extremely” happy that I chose Unionville Heating from day “one”. Continue with the great work.

    Karen P Markham
  • Excellent customer service!

    Mary Joanne M Markham
  • I have used Unionville Heating and Air Conditioning for the last 5 years, for annual heater and air conditioner maintenance. They send the same technician out to your house, twice a year, for maintenance. My technician, Jason, has always been on time, friendly, and knowledgeable. He keeps my HVAC systems in peak condition, and has recommended and performed repairs as needed. He applied for parts that were under warranty for me, and because they service the HVAC systems in my house annually, they don't charge a call-out fee (just the hourly fee for actual work performed) for repairs. I love that I can trust that it will be the same friendly person coming into my house every time!

    Homeowner Markham
  • Unionville Heating and Air Conditioning replaced my very old furnace and air conditioning units about 3 years ago. The quote was competitive and on installation day a crew of 4 showed up and installed the new systems. They were courteous, efficient and took care to a very detailed level. All in all, a very professional job taking care not to make a mess. They even needed to move my gas-fired hot water tank a bit to accommodate the new furnace and filter. So the gas line and water line connection to the tank had to be moved a bit. No extra charge. I signed up for the annual maintenance and warranty extension. Very happy with the installation. No issues. Saving big, as my gas heating consumption is now about one third of what it was before and hydro cooling charges in the summer are down too.

    G Markham
  • We have Unionville in for the yearly maintenance on heating and cooling systems, and they have been very professional, courteous, clean and prompt. They communicate with us when things need to be dealt with, and provide good timelines for when we need to start to look at replacement of any wear items. Recommended.

    Mike Markham
  • Shortly after I moved into my house, I had the air conditioner and furnace serviced by Unionville Heating and Air Conditioning. They had great appointment times, showed up exactly at the time that they had specified, and were polite and professional. Included in these two services, I was placed on their annual maintenance contract, which means that if I need to call them for any reason, I will only pay the hourly service fee, and not any emergency or call-out fees. They also noticed a worn part on my furnace. It was under warranty, and they made all of the calls and arrangements for the spare part, and returned to fix it once it came in. They did a great job, and I would definitely recommend them!
