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.

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!
