SLP98V Variable-Speed reviews
Reliable through a brutal winter
"Survived our first -30 cold snap without a hiccup. Steady, warm, and the variable-speed blower is so quiet we forget it's running."
— Priya R., Burnaby · 2025-05-26
Worth the upgrade
"The monthly payment made the high-efficiency model affordable. Rebate covered a big chunk and the savings on our bills basically cover the payment."
— James G., Surrey · 2025-06-06
Quiet and efficient — bills dropped
"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."
— Nicole M., Toronto · 2025-07-13
