Fast, effective service. Going to bed Friday night, discovered no furnace heat on the current coldest night of the year. Called MacKay service line, talked to the weekend service guy. He arrived early the next morning, diagnosed the problem, had the required part in his truck. Replaced the part and confirmed the furnace was now running properly. Thanks Josh for a job well done.

They installed a replacement cold-weather heat pump on my existing furnace. The estimator, Fred, was courteous, knowledgeable and straight forward. The crew did a great job of installation and clean up. The system appears to be working very well.

MacKay Heating and Cooling came quickly when called. Andrew arrived on time and outlined our options. With a 44 year old furnace and 35 year old air conditioner ( Mac Kay 1989) it was time for replacement. A new HVAC system plus a hot water tank was ordered and installed by a very professional team who worked steadily for two days completing the install, clean up and set up of the system. Quite amazing.After the first weekend with our new furnace we are pleased to have heat evenly distributed throughout house – a first for us. Lots of hot water too!Being family run & locally owned was a bonus. We highly recommend MacKay Heating and Cooling.

It’s been 11 years since MacKay Heating and Cooling installed our Veisman boiler and hot water tank. We have used their yearly service in order to keep our home worry free from heating issues. Service techs are very knowledgeable and provide preventative maintenance tips in order to prevent any subsequent failures. Excellent service year after year.

Cameron arrived promptly and worked efficiently. He was personable and easy to chat to. Very thorough in his examination of my heating/cooling/humidifier systems, and he spent time adjusting my programmable thermostat so that even I can operate it. Great work all round, thank you.
