Ashley and Spencer we’re here for 1 1/2 days and did a great job. They were very pleasant and knowledgeable, providing us with updates as the job (remove existing furnace and air conditioner and install new equipment) progressed. When the job was complete they gave us a “tour” with explanations of all they had worked on and answered the questions we had. Overall, they would have our recommendations.

Don and Chris were fantastic. Had a bit of wait for AC to be installed, but to be expected during this hot, humid, covid summer. They arrived on time and installed AC without any incident. SO relieved to have air conditioning again and love new thermostat, thanks Chris! Staff is friendly and professional and my house is COLD 😁

Don and Chris were fantastic

Super fast, friendly service – we had a smaller job, just to relocate an outdoor gas line for a barbecue, and they were able to fit us onto another job in the area and got us up and running a week earlier than planned. 100% would recommend

Super fast, friendly service

Their sales and service personnel are outstanding. Salesman Chris Whelan conducted extensive research on our behalf to find the perfect gas fireplace to meet our needs and provided us with a quote that clearly delineated the installation work and associated charges to ensure there would be no surprises when it came time to pay the bill.
Don’s Heating & Cooling then sent us “the dream team” of Mike and Brendan to do the installation. They were a delight to have in our home and they did a superb job with the installation in a very timely fashion.
It was apparent with all three of Don’s team that they take pride in their work and in meeting and exceeding their client’s expectations. Definitely 5 star service!

We ordered a Napoleon BBQ by phone. Johanne was very knowledgeable and she worked hard to find the BBQ we were looking for. It was delivered as promised despite the real bad weather we were experiencing. Thank you Sam.

Customer service at its best, way beyond expectations!

Friendly, Professional and Well-Priced! What more can you ask for!?! Bought my furnace from them a few years ago. First and only call I needed when I needed a new AC unit.

Friendly, Professional and Well-Priced!

We recently purchased and had installed a new Carrier High Efficiency 2 stage furnace with a variable speed ECM motor and a Carrier air conditioner by Don’s Heating and Cooling. The in home assessment by Paul, his recommendations on how to increase the air supply to the new HVAC system and the quote were the best of the three companies we contacted. The removal of the old forced-air electric furnace and the install of the new propane furnace and air conditioner by the technicians Mike and Chris was amazing. The furnace and AC, and the lines, wires, conduits, air vents and grills were installed neatly and with precision. They stayed well into the evening on two 12 hour days to complete this big job and they did it with care as if it were their own home. The ladies at the office were a pleasure to deal with. We were very impressed! Dr. Ryan and Wendy de Langley
