Kerry Waddell
Amazing experience with SunnySide Heating and Air Conditioning! Great people and completed all the work in a timely and transparent manner, even explaining to me steps along the way that I didn't understand. They responded immediately to our need for a furnace check up and had a new furnace installed within 12 hours! Would highly recommend.

Kevin has helped us with our furnace issues. The extreme cold we have been having this winter exacerbated the heating system and our furnace was constantly shutting off and on. Our furnace was running 24/7 even on a mildly cold day. We have more work to do on our own to fix things permanently, but we appreciate Kevin coming to our rescue on short notice when our upper floors (where our tenants live) dipped to 15.5 degrees Celsius after a major cold snap. Kevin is knowledgeable, kind, and patient, and I’m glad I gave SunnySide a chance. They also send helpful appointment confirmations, reminders, and invoice notifications! Making payments is also very easy. Thank you SunnySide and Kevin.

I had an excellent experience with SunnySide Heating and Air Conditioning. They installed a new air conditioner unit, worked on our radiators, and completed several system repairs on the furnace. From start to finish, their service was professional, friendly, knowledgeable, and efficient. The team took the time to clearly explain all the work that needed to be done, provided prompt and reliable service, and reviewed everything with me once the job was complete. They patiently answered all of my questions and made sure I was comfortable with the work performed. I truly appreciate their attention to detail and customer-focused approach. Highly recommended!

Excellent service from start to finish! The team replaced my furnace and hot water tank and did an outstanding job. They were professional, knowledgeable, and very clean throughout the entire process. Everything was explained clearly, the installation was done on time, and the system is working perfectly. You can really tell they take pride in their work. I highly recommend them to anyone looking for reliable and high-quality HVAC service.

Professional, prompt and efficient!! The Sunnyside team helped us regain heating during the coldest week of the month within 24 hours from identifying the issue, recommending the most reasonable solution, to completing the replacement job. We felt very well looked after, a rare gem and highly recommend!
