About Reliance Heating, Air Conditioning & Plumbing
Reliance Heating, AC & Plumbing, Mississauga, ON, has operated in Ontario for more than 60 years and runs a dedicated Mississauga branch, and its Google page currently averages 4.8 stars across 22,768 reviews, read September 23, 2026, by far the largest review base of any HVAC company in this Mississauga ranking.
The company holds an Electrical Safety Authority license (ESA #7012884), carries WSIB clearance, and is BBB accredited, and was certified a Great Place to Work in 2025. It installs SmartAir, Carrier, Trane, Rinnai, Mitsubishi, Bosch, and Lennox equipment, and its service list covers furnaces, air conditioners, heat pumps, tank and tankless water heaters, plumbing, electrical work, water purification, and EV chargers, a genuinely broad multi-trade operation that goes well past heating and cooling alone.
Reliance offers 24/7/365 service backed by a "next day or we pay $500" installation guarantee, and rental options for furnaces, AC units, and water heaters starting around $19.99 a month rather than requiring an upfront purchase, a structure aimed at homeowners who would rather spread the cost than pay for equipment outright.
Service reaches Mississauga and the wider Greater Toronto Area as part of a national network.
Being a large, established national name shows up in the review count as much as anything else on this list: past 22,000 reviews is an order of magnitude more feedback than most local shops accumulate, and a 4.8-star average holding across that volume says the service is consistent rather than a handful of good weeks.
Reliance suits a homeowner who wants a large, well-resourced company with genuine round-the-clock coverage and rental options rather than a big upfront cost. It suits less well someone who wants a small, personal local shop. Ask for the technician's TSSA licence number to confirm and current rental versus purchase terms before booking.
