What Our Customers Are Saying
MacKay installed my furnace and hot water tank 16 years ago and I have had the furnace maintained by them over the years. The staff are efficient and friendly and I highly recommend this company.
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.

Just got a new furnace, A/C and hot water tank and we were happy with the experience. The sales and service personnel were professional, arrived on time and finished ahead of schedule. Would highly recommend.

Hi Kevin, thanks for your 5 star rating and kind comments! We appreciate your continued business and recommending us with enthusiasm! 🙂 You’re absolutely right that we have Tech’s on call after hours, even on a snowy night, for emergency situations like no heating. Thanks again and we’re always here if you need us in the future.
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 .

Hi Quinton, thanks for your 5 star rating!
He was friendly and professional. Didn’t seem rushed. Took his time to do the job right. Was patient in explaining to me what he was doing during the process and answered my questions with respect.

Hi Dave, thanks for your 5 star rating and kind words about your recent experience with MacKay! We’re always here if you need us again in the future!
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.
