Tempstar reviews
Exactly what we needed
"We went with a two-stage model on the recommendation here and it holds temperature perfectly. No more big swings between the thermostat cycling on and off."
— Daniel G., Mississauga · 2025-09-09
Warm house, lower gas bill
"Got three quotes through the marketplace and picked the mid-tier option. Install was clean, the crew was respectful of our home, and everything works great."
— Sophie M., Winnipeg · 2025-10-16
Professional from quote to install
"Survived our first -30 cold snap without a hiccup. Steady, warm, and the variable-speed blower is so quiet we forget it's running."
— Jennifer R., Burnaby · 2025-11-23
Best decision for our home
"The monthly payment made the high-efficiency model affordable. Rebate covered a big chunk and the savings on our bills basically cover the payment."
