Words from our Clients

Our success is measured by the satisfaction of our customers. Check out some of our clients’ stories below.


I can’t be happier with this company. I’ve been with them for over 10 years and never had a problem. They service my burner and split units, which they installed, along with delivering oil. I’d go 6 stars if I could.”


George V.

“MacKenzie has been very accommodating for me over the last 10 years. I’ve had them install a new furnace as well as a direct vent gas fireplace. They’re very responsive for maintenance and repairs. I would definitely recommend them.”


Gerry M.

“MacKenzie Heating & Cooling does have the best oil pricing…they’re very professional and helpful…My oil tank was leaking I called them and the same day they fixed it…they certainly gave me peace of mind…I would give them a 10 star rating.”
