We service, repair, and install all major commercial and industrial heating, cooling, and ventilation systems, including:
We offer 24/7 emergency response across Toronto and the Greater Toronto Area (GTA). For critical emergencies—such as refrigeration loss in restaurants, boiler shutdowns in apartment buildings, or RTU failures in warehouses—our licensed technicians respond immediately to minimize business disruption and prevent asset loss.
Preventative maintenance protects commercial assets, reduces emergency repair costs, maintains energy efficiency, and keeps facilities compliant. Our tailormade PPM schedules ensure filter changes, belt replacements, burner cleanings, and system diagnostics are performed before minor issues cause major operational downtime.
Yes. We service commercial kitchen exhaust hoods, makeup air units (MAU), walk-in coolers and freezers, gas lines, and gas cooking equipment for restaurants and food processing facilities across the GTA. Proper kitchen ventilation balance is essential for safety, odor control, and fire code compliance.
Makeup air units pull fresh, condition-treated air into a building to replace air exhausted by hood fans and process equipment. Without an operational MAU, buildings experience negative air pressure, leading to heavy entry doors, backdrafting carbon monoxide from heating appliances, and inconsistent indoor temperatures.
Common indicators that an RTU needs attention include:
Service intervals vary by equipment type:
Yes. Our field team consists of licensed G1 / G2 Gas Technicians, certified 313A Refrigeration & Air Conditioning Mechanics, and experienced HVAC professionals. We carry full commercial general liability insurance and WSIB clearance for commercial and industrial jobsites across Ontario.
Yes. Modern variable-speed RTUs, condensing boilers, and smart building management controls operate with far higher efficiency than older equipment. Replacing 15+ year old systems can reduce heating and cooling energy consumption by 20% to 35% while drastically lowering maintenance expenses.
For industrial facilities, we specialize in high-efficiency tube heaters, direct-fired unit heaters, warehouse ventilation fans, and custom maintenance schedules configured around your operating hours to maintain zero operational disruption to logistics or manufacturing work.
