Heating & Cooling
Heat pumps: one system that heats and cools, all year.
Heat pumps are the fastest-growing part of Ontario’s comfort market in 2026 — and for good reason. A single cold-climate heat pump both heats and cools your home efficiently, and it’s eligible for the largest rebates available.
