ML180E Single-Stage reviews
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 · 2025-11-14
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."
— Ahmed G., Surrey · 2025-12-21
Even heat in every room
"Replaced our 20-year-old furnace and the difference is night and day. The house heats evenly and it's noticeably quieter. Our gas bill dropped about 25% over the winter."
— Linda M., Toronto · 2025-01-01
