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.

The folks at MacKay heating and cooling are friendly, professional, prompt and go out of their way to get to you quickly and resolve problems. We’ve been using them for years and have always been happy even when they are called upon in the middle of the snowy night. I recommend them with enthusiasm.

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 .

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.

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.

We recently moved to St. Catharines and had great experience with MacKay Heating & Cooling. One evening our hot water tank had stopped working properly, so the next morning I called to see if someone could fix the issue. Brenda was kind and very helpful in scheduling an appointment later that day and Andrew whom preformed the maintenance and also serviced our furnace ahead of the winter months arrived within the scheduled window. He was very friendly, polite and professional. The price was fair and communicated up front ahead of the appointment. I would 100% recommend to anyone and will use them again for future service work.

I had a very positive outcome when I called MacKay Heating and Cooling to give me a quote on a new hot water tank.
The technician not only checked out the hot water tank but looked at the furnace and solved our leak.
Thanks

Today I had a visit from Tyler who completed a maintenance service on my furnace . I was most impressed with his knowledge, friendliness and professionalism. He took time to explain everything to me and to make sure I was completely satisfied with his service. I would certainly recommend his service to anyone looking for a maintenance call. Thank you for helping with my nest thermostat and humidifier. A great experience.

We have dealt with Mackay’s for over forty years and they have always proved to be forthright and reliable. Our recent heat pump installation went without a hitch. We have recommended them to many family and friends – all were very satisfied with their service.

Excellent company, professional service, amazing staff! I cannot recommend this company enough! I called in order to get my outdoor heating and cooling unit serviced. Josh was super friendly, arrived on time, and happily answered all of my questions. He thoroughly cleaned the outdoor unit while also performing the annual service. Josh was also great at walking me through how to change the air filter if I ever wanted to change it myself. Wonderful company that clearly puts the customer’s needs and interests first! I will continue using them for all my heating and cooling needs!

This company is one of the most professional in the field! Techs are knowledgeable, friendly and efficient.
They are forthcoming if they feel a part needs replacing or repairing. Prices are very fair.
In short, I have no hesitation in strongly recommending MacKay Heating and Air Conditioning!
