Great service done by Steve, who came and efficiently cleaned and got my furnace ready for the season. I had a call to book appointment for cleaning, and a reminder call for when tech was on way. Well done!!

We have used MacKay Heating since purchasing our home 15 years ago. We have used them to replace our furnace and air conditioner as well as maintenance calls. We have always been very satisfied with their service and response to issues. I’d highly recommend them.

From start to finish, the service was great. The two guys who were here were very polite and cleaned the area after they finished. We have been dealing with this company for 24 years. They installed our first furnace in 2001 and have maintained the furnace all throughout this period. I will recommend them again and again.

This is my 1st experience with MacKay heating . After my regular service company responded , in late October , to my request to perform my annual furnace maintenance service in November . Sorry , we have not started to book November yet was the response . This was the same company I purchased my new furnace from 3 years ago , and this year measured up for a new Air Conditioner and never provided a price . ‘ HOW DO SOME COMPANIES STAY IN BUSINESS ?
MacKay was different . They were immediately on the ball . Most cooperative , friendly and professional in customer relations
In this instance , SERVICE WITHIN 1 WEEK . The service technician was equally personable and a REAL PROFESSIONAL .
As a former Metal Manufacturing business owner and Mechanical / Aeronautical Engineer . I appreciate a company who puts the customer 1st . and knows their stuff .
I would not hesitate recommending MacKay Heating & Cooling for your HVAC requirements . An 11 out of 10 .
