Our Take on Boonstra Heating and Air Conditioning

About Boonstra Heating and Air Conditioning
Boonstra Heating and Air Conditioning has operated in Hamilton since 1961, giving it more than 60 years of local history, and its Google page currently averages 4.7 stars across 5,103 reviews, read September 22, 2026, the largest review base of any company on this list.
The company holds TSSA license FS-R-52551 and carries a BBB B+ rating. Its award list is unusually long for a local HVAC shop: HomeStars Best of 2020, Readers Choice Platinum 2025, a Consumers Choice Award, and a Three Best Rated recognition for HVAC services. The service list covers heating, cooling, plumbing, heat pumps, water heaters, drain cleaning, humidifiers, UV air purifiers, water filtration systems, and sump pump installation, with brands including Amana, Bradford White, Goodman, and Gree.
Boonstra advertises 24/7 emergency service with no after-hours charge, a genuine point of difference from companies that add a premium for evening or weekend calls. Financing is available on approved credit, and the company backs its work with a stated satisfaction guarantee, though specific warranty terms and durations aren't detailed. No individual owners or technicians are named on the site, and a direct company email isn't published. The phone number on the company's own site differs from the one listed on its Google profile; this listing uses the Google number.
Service reaches an unusually wide area for a single-location company: Hamilton, Ancaster, Binbrook, Burlington, Dundas, Brantford, Lincoln, Flamborough, Grimsby, Milton, Caledonia, Mount Hope, Oakville, Stoney Creek, Waterdown, and Hagersville.
Boonstra suits a homeowner who wants a long-established, heavily reviewed company with a genuine no-surcharge 24/7 policy and plumbing alongside HVAC. It suits less well someone who wants a company with a higher BBB letter grade or named staff to research beforehand. Ask for the technician's TSSA licence number directly and confirm current after-hours policies before calling.
