Every service your climate needs.
From the first furnace to the last filter, Gowling Groupe covers the full spectrum of HVAC for homes and businesses across the Greater Toronto Area — heating, cooling, ventilation, air quality and the maintenance that keeps it all in balance.
What we do
Full-spectrum HVAC, under one roof.
Nine core services covering every part of the cold-to-warm range — engineered, installed and maintained by one licensed team.
Air Conditioning
Central AC and ductless mini-splits for even, quiet cooling. Whether you’re adding comfort to one room or the whole home, we size and place it to cool without cold spots or noise.

No heat, no cool, strange noises or climbing bills? We diagnose the real cause — not just the symptom — and repair all makes and models with upfront, written pricing.

Seasonal tune-ups that catch small issues before they become winter breakdowns. Our maintenance plans hold efficiency, protect your warranty and put you first in line.
See plansIndoor Air Quality
HRV/ERV systems, humidifiers, advanced filtration and purification that make every breath cleaner and more balanced. Less dust, fewer allergens, steadier humidity, healthier air.
Improve my airVentilation & Ductwork
Duct design, sealing and balancing so conditioned air actually reaches every room. We find the leaks and restrictions that quietly waste energy and leave spaces uneven.
Balance my homeThermostats & Controls
Smart thermostats and zoning that give every area its own set point. We install, wire and configure controls that save energy and let you manage comfort from anywhere.

Installation done the engineered way.
A new system is only as good as the install behind it. We don’t swap box-for-box — we calculate the load, design the airflow and commission the system so it performs the way the manufacturer intended.
- Room-by-room load calculation before we quote
- Furnaces, heat pumps, boilers and AC — all major brands
- Rebate and financing paperwork handled for you
- Clean removal, tidy install and full commissioning
- Workmanship warranty up to 10 years available
Calculated first, commissioned last.
Steady, season after season.
Maintenance
Maintenance that prevents the 2 a.m. call.
The cheapest repair is the one that never happens. A planned tune-up before each season keeps efficiency high, parts clean and your warranty intact — and gives our technicians the chance to flag small problems early.
- Heating and cooling tune-ups timed to the season
- Multi-point inspection with a documented report
- Priority scheduling and member-only repair discounts
- Filter, humidity and safety checks every visit
