What GTA homeowners say
Over 15 years of trusted service across Toronto, Markham, Vaughan and the wider GTA.
"Our central AC stopped working on the hottest day of the summer. HVAC BOSS came out the same day, diagnosed a failed capacitor, and had it running within an hour. Mehrdad was professional, explained everything clearly, and the price was fair. Highly recommend."
Sarah M.
Markham, ON · AC repair
"We replaced our 20-year-old furnace before winter. HVAC BOSS gave us a straightforward recommendation without trying to upsell us on features we didn't need. The installation was clean, they cleaned up completely, and the new furnace has been running perfectly."
David K.
North York, ON · Furnace installation
"We switched from a tank to a tankless water heater. The team walked us through the whole process, completed the installation in one visit, and took the time to explain how to use the new system. No mess left behind. Very happy with the result."
Linda T.
Vaughan, ON · Tankless water heater
"Furnace went out on a Friday night in January. Called HVAC BOSS and they were at our door within two hours. Fixed the igniter, tested everything thoroughly, and our heat was back on the same night. That kind of reliability is hard to find."
James R.
Scarborough, ON · Emergency furnace repair
"Had central air installed for the first time in our older home. HVAC BOSS assessed the layout carefully, recommended the right size unit, and the installation was done in a day. The team was respectful of our home and left everything spotless."
Priya S.
Toronto, ON · AC installation
"Booked an annual furnace maintenance before the heating season. The technician was thorough, found a minor issue before it became a bigger problem, and explained exactly what was done. Great value and peace of mind going into winter."
Michael C.
Etobicoke, ON · Furnace tune-up
"Our AC was blowing warm air and making a strange noise. HVAC BOSS diagnosed a refrigerant leak and a worn fan motor. Both were fixed in one visit. The technician was honest about what was needed and what wasn't. Will definitely call again."
Angela W.
Richmond Hill, ON · AC repair
"Our water heater started leaking on a Sunday morning. HVAC BOSS came out, confirmed it needed to be replaced, and had a new unit installed by the afternoon. Fast, professional, and no surprises on the bill. Exactly what you want in an emergency."
Tony B.
Toronto, ON · Water heater replacement
"I've been using HVAC BOSS for annual AC tune-ups for three years now. Consistent, reliable service every time. They always call ahead, arrive on time, and take care not to track anything through the house. Wouldn't use anyone else."
