Toronto Commercial HVAC runs a 24-hour emergency line for commercial HVAC and refrigeration across Toronto and the GTA. Emergency calls get a 2-4 hour response, day or night, for rooftop units, chillers, boilers, make-up air, walk-in coolers and freezers, and building controls. Every technician on the emergency rotation holds the same TSSA, ESA and 313A licences as our day crews.

Commercial emergencies are about money and risk by the hour. One hour of walk-in freezer failure can mean $8K in lost product. A server room without cooling can overheat in under an hour. A boiler failure in a -20C week can freeze pipes and sprinkler lines. A chiller failure in a hospital puts patient care areas at risk. That is why we route restaurants, grocery and healthcare first, and why contract customers get priority on the line.

After-hours calls carry a $185 surcharge plus standard repair rates. Standard diagnostics are $185 for HVAC and $225 for refrigeration, and you get a written quote before work starts.

What Counts as a Commercial HVAC Emergency?

  • Refrigeration failure with product at risk: walk-in freezers, coolers, prep lines, display cases. See commercial refrigeration repair.
  • No heat during freezing weather, especially where pipes or sprinkler lines can freeze.
  • No cooling in healthcare, labs, server rooms or buildings during a heat warning.
  • Gas smell or CO alarm. Leave the building and call your gas utility first. We repair and clear the appliance afterwards.
  • Water leaking from equipment into occupied space or onto electrical gear.
  • Total system shutdown affecting operations.

How Our Emergency Response Works

Triage

Dispatch takes the building, equipment, symptoms and risk. Product, patient and safety risk set the priority, and contract sites move up the queue.

Stabilize first

On arrival the first job is to make the site safe and protect what matters: shutting down unsafe gas appliances, moving product to a reefer, staging temporary cooling or heat.

Repair from truck stock

Trucks carry contactors, capacitors, fan motors, igniters, ignition modules, boiler controls and refrigeration parts. About 80% of the Toronto commercial RTU fleet is covered from stock.

Report

A written report with findings, readings, parts and follow-up work goes to your file the next business day.

Common Emergency Scenarios We Handle

Walk-in freezer down on a Saturday night

Low-temp compressor, defrost or controller failure. We move product to a reefer if needed, repair the system and monitor thermal recovery. Details on walk-in freezer repair.

Heatwave lockouts

The first week above 32C brings waves of high-pressure lockouts and failed fan motors. Crews are staged before the heat arrives.

Cold-snap no-heat calls

The first week below -15C brings ignition and boiler failures. Temporary heat is available while parts arrive. See commercial boiler repair.

Hospital or lab cooling loss

Temporary chillers are staged the same day while the permanent repair proceeds. Our downtown hospital chiller emergency had temporary cooling running the same afternoon.

Reduce Emergencies Before They Happen

Most emergency calls trace back to something a maintenance visit would have caught: a pitted contactor, a fouled coil, a weak igniter, an iced evaporator. Sites on commercial HVAC maintenance programs get fewer emergencies and priority routing when they do happen.

Straight Answers

24-Hour Emergency FAQs

How fast can you respond to a commercial HVAC emergency in Toronto?

Emergency calls get a 2-4 hour response across Toronto and the GTA, 24 hours a day, including weekends and holidays. Restaurants, grocery and healthcare sites get priority routing because product and patient risk climbs fast, and contract maintenance customers move to the front of the queue. Dispatch confirms an arrival window by phone, and the technician calls ahead to sort out roof access, keys and security sign-in so no time is lost on arrival. Our Vaughan grocery contract averaged a 2:40 response through 2025 with zero product loss, and our downtown hospital chiller emergency had a crew on site in under three hours.

How much does emergency commercial HVAC repair cost?

After-hours calls add a $185 surcharge on top of standard rates. The standard diagnostic is $185 for HVAC and $225 for refrigeration, and the HVAC diagnostic is waived on repairs over $750. Repair pricing is the same as daytime once the technician is on site, and you get a written quote before work starts. Temporary cooling, heat or refrigeration equipment is quoted separately when a repair will take longer than the building can wait.

What counts as an emergency?

Loss of refrigeration with product at risk, no heat in freezing weather, no cooling in healthcare or server rooms, gas smells or CO alarms, water leaking from equipment into occupied space, and any failure that shuts down operations. If you smell gas, leave the area and call your gas utility first.

Do you handle walk-in freezer emergencies overnight?

Yes. Walk-in freezer and cooler failures get top priority on the 24-hour line, with 313A refrigeration mechanics on call. We also help arrange reefer trailers when product must be moved.

Can you provide temporary cooling or heat?

Yes. Temporary chillers, portable cooling, temporary heaters and refrigeration can be staged the same day when a permanent repair needs parts or more time.

Are night-shift technicians fully licensed?

Yes. Emergency calls are handled by TSSA, ESA and 313A licensed technicians, the same people who work days.

Do you serve the whole GTA after hours?

Yes. 20+ GTA cities, with dedicated crews for Downtown Toronto, Mississauga, Vaughan, Brampton, Etobicoke, North York, Scarborough and Markham.

Do contract customers get faster emergency service?

Yes. Sites on a maintenance program get priority routing on the 24-hour line.

Is there a warranty on emergency repairs?

Yes. The same 90-day labour warranty as any repair, with manufacturer parts warranties passed through.

What should we do while waiting for the technician?

Keep walk-in doors closed, move critical product if you can, turn off equipment that is short cycling or making grinding noises, and clear access to the roof hatch or mechanical room. Dispatch will tell you anything else specific to your equipment.
