Finding a reliable HVAC company in Scarborough has never been easy. With dozens of options and aggressive marketing from national chains, how do you separate the pros from the pretenders?

We did the work for you. Over three months, we surveyed 400+ Scarborough homeowners about their HVAC experiences, cross-referenced every response with BBB ratings, Google reviews, TSSA licensing records, and manufacturer dealer certifications.

The Criteria

Companies were scored on response time, pricing transparency, workmanship quality, warranty honoring, and post-install support. Only TSSA-registered companies with active insurance were eligible.

The Top 5

1. ArcticComfort HVAC — 4.88 rating, 98 verified reviews. Authorized Lennox dealer with same-day emergency service.

2. CoolAir Systems — 4.65 rating, 72 reviews. Greener Homes certified, excellent heat pump installations.

3. ClimateGuard HVAC — 4.35 rating, 41 reviews. Best value for annual maintenance plans.

4. Northern Comfort — 4.28 rating, 55 reviews. Strong in ductless mini-split installations.

5. GTA Climate Control — 4.20 rating, 38 reviews. Best emergency response times in eastern Scarborough.

Ontario’s popular Enbridge HER+ rebate may be closed, but heat pump incentives are far from dead. In 2026, homeowners can still claim between $2,000 and $7,500 through the restructured Home Renovation Savings Program and Save on Energy, with income‑qualified households eligible for free full-system upgrades. Your rebate amount now depends on how your home is heated—gas, electric, or mixed—and whether you install a central cold‑climate heat pump or a ductless multi‑zone system. However, applications are strict: you must use an HRAI‑registered contractor, install an AHRI‑matched system, and include a qualifying smart thermostat for hybrid setups. With average GTA heat pump installations ranging from $9,500 to $14,500, these incentives significantly reduce out‑of‑pocket costs for homeowners replacing aging furnaces or AC units.
