My boiler needed service and one of my radiators was leaking. I called and had a team out the next day to fix the issues. They went above and beyond to make sure everything worked perfectly. I couldn’t have asked for better service and at an excellent price!

In June I had a new furnace and A/C installed replacing the old. Brady, Jesse and Tyler were great! Professional, polite, tidy and answered all my questions. A great price !Everything was done at the times given. Due to the flooding, I called to have them check out my furnace that all was well the morning after all the rain. They were here the next day and happily everything was working well. Even answered more of my questions! So happy that I chose Mackay Heating & Cooling!

I recently had Mackay Heating & Cooling install a heat pump in my home, and I can't say enough good things about the experience. From the first conversation with their Sales team through to the final installation, every single person I interacted with was friendly, knowledgeable and professional. Their pricing was fair and transparent – no surprises – and the quality of service was outstanding from start to finish. What really stood out was their reliability. They met every commitment which is refreshing and all too rare these days. If you're looking for a heating and cooling company you can trust, look no further. I would recommend Mackay with complete confidence.

Ryan showed up on time for the appointment and had sent a notification he was on the way. Always appreciated. Ryan did a thorough examination of our boiler, heat pump and indoor units. Filters and outdoor unit were cleaned. He answered my questions and gave me an update on the status of everything when he finished. Glad to hear everything is ready for the new season. Ryan was courteous and neat. Would welcome him again.

Brady made this entire process painless. He was polite, friendly and efficient. He took time to explain what would be happening and took pictures so that I could see the changes (very thoughtful as I am mobility challenged). The use of booties and even a red carpet on my basement stairs to ensure there would be no mess for me to clean up was much appreciated. There was no pressure from Fred, the salesman, in any decision making and they were able to give me an appointment fairly quickly. Many thanks to all involved. I would definitely recommend MacKay Heating and Cooling.

I found McKay's at the St Catharines Home Show back in 2014. We picked them because they were knowledgeable on the subject heat pumps – they installed a new furnace and heat pump for us a few months later – and we have been dealing with them ever since. Everyone we have dealt with has been extremely nice and more importantly, they all go out of their way to provide top quality service. It has been a pleasure dealing with everyone at MacKay Heating & Cooling, with much appreciation.
