What Customers Say

“Had my air conditioner maintenance done today. Your staff who initially called to set it up were very kind and personable and took the time to set up a time that worked for me. The maintenance man, Mart, did a thorough job, was very friendly, and answered any questions I had. He has done the furnace maintenance as well, always very kind and personable as well. I highly recommend this gentleman and Boonstra Heating and Air Conditioning.”

Heating & Cooling in Hamilton, Burlington, Oakville, & Surrounding Area

We’ve been providing heating and cooling services ever since Clarence Boonstra installed his first furnace in 1961. Today, we have grown to deliver heating and cooling services to homeowners from all over southern Ontario.

Frequently Asked Questions

Generally, a repair technician will be out to help within 4 hours of the call being made. We almost always are able to complete a repair the same day.

No, last-minute or urgent repairs cost the same as any other. We never charge extra for repairs, even if they are needed on weekends, evenings, or holidays. Call us any time, we’re available 24/7.

Absolutely. The best way to do this is by having your air conditioning unit undergo a yearly maintenance check by a licensed technician. They will complete a thorough review of your A/C and assess how it is operating to determine whether it is at its best, and tune it up if needed.
