SL280V reviews
Warm house, lower gas bill
"The installer walked us through the financing and rebates, handled all the paperwork, and had us up and running in a day. Couldn't be happier with the comfort."
— Marc R., Calgary · 2025-08-20
Professional from quote to install
"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."
— Karen G., Mississauga · 2025-09-27
Best decision for our home
"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."
