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.

It was easy booking with MacKay and they were transparent with the pricing. Tyler did a great job with our AC maintenance. He arrived on time and was efficient. We will definitely reach out to them again for future HVAC service.

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.

I contacted Mackay Heating & Cooling for a quote on a new hot water tank. Tyler arrived at our home within an hour and was very friendly and professional. He provided a detailed quote at no charge, which we really appreciated.

We decided to move forward with the installation, and Chris and Zack came the next day. They removed the old tank and installed the new one within a few hours. The whole process was smooth and efficient.

We’re very pleased with their work and the excellent service from the entire team. I would definitely recommend this company to anyone looking for reliable heating and cooling services.

I called at 930 pm for an emergency service call. The young man was very polite and thorough on the phone. He arrived on time. He explained clearly what he had done to assess the problem. Diagnosed and fixed the issue within an hour. Super personable and very professional. I highly recommend this company.

After doing initial research, found MacKay Heating & Cooling was top of recommended local companies for tankleess hotwater , HVAC service, installation and maintenance. After meeting with Fred for quotation, i was impressed with experience and knowledge. This convinced me to go with them. When I phoned office to accept quote, the friendly office personnel quickly provided helpful service and advised a install date with expected time of arrival on date. On day of install a text message was sent by tech to advise they were on their way. The first tech Dave arrived at 8:03 to layout floor mats on exposed floor so they could not cause any mess while coming and going. As well to start drain of existing tank. Chris showed up shortly after and the removal of old and install went very well. A highly professional crew and final result was exceptional, piping for water, venting, natural gas and drainage were clean and square.
I highly recommend MacKay’s team of professionals.

One of those absolutely perfect service calls. A job extremely well done with a very knowledgeable, professional and pleasant technician. And as well a very pleasant and knowledgeable person at the end of the phone line when I booked this. The quoted price when booking over the phone was exactly what I ended up paying.I highly recommend MacKay heating and cooling and the technician David.
