Today I had the good fortune to have a Mackay technician diagnose and repair our pool heat pump…read more Dan Swords was able to diagnose a faulty voltage boost capacitor within minutes. I was so happy because I feared that many other complicated problems that would suggest I had buy a brand new heat pump. Dan also did a thorough cleaning of the filter, coil fins. The freon level was also checked, no leaks. Dan cleared any other issues that may have caused the heater to default, only having to replace the voltage boost capacitor. I am so happy to have had this level of professionalism! Thank you Dan Swords, you rock! Tom Bonic

Our furnace broke down and Mackay was able to send a technician almost immediately. He gave us…read moreseveral options for repair, but we ultimately decided that it would be more cost-effective to purchase a new furnace. Given the fact that we had no heat, they made all attempts to accommodate us by sending the salesman within 24 hours. The salesman spent a lot of time with us, ensuring that we had all the information we needed to make our decision, and the new furnace was installed the next business day. From the beginning to the completion of our association with this company, we found them courteous, professional, polite, and anxious to ensure that we were happy with their work. They left the site clean, and even came back when they realized they had missed one small aspect of the job. They all wore masks and we felt very safe with them in our home. We would highly recommend Mackay Heating and Cooling.

However no one called me to confirm a time so I emailed them through Kijiji wanting to confirm and the answer I got was that they only have service trucks in Windsor on the 23rd and 29th and 23rd didn't work for me so they can't come. This is not how a business is run when you tell someone you've booked an appointment you show up.
