How Our Emergency Response Works
From your call to heat restored - here's exactly what happens.
Call Us 24/7
A live technician answers - not a call center. We assess your situation immediately.
Dispatch Within 1–2 hrs
The nearest available TSSA-certified tech is dispatched to your location.
Diagnose & Quote
We diagnose the issue and give you a firm price before any work begins.
Repair & Restore Heat
Most emergency repairs are completed same visit. We carry common parts on every truck.
$0 Overtime Fees - Always
Most GTA HVAC companies charge 1.5x–2x their normal rate for emergency, after-hours, weekend, or holiday calls. EcoFrost charges the same flat rate no matter when you call.
2 AM on Christmas Eve? Same price as a Tuesday afternoon. We believe a heating emergency shouldn't also be a financial emergency.

What counts as an HVAC emergency?
Any situation involving no heat in winter, no cooling during a heat warning, a carbon monoxide detector trigger, a gas smell, or an Enbridge red tag shutting down your system. These all require same-day emergency service.
How fast can you respond to an emergency in Mississauga or Toronto?
Typical response time is 1–3 hours across the GTA. We cover Mississauga, Toronto, Brampton, Vaughan, Markham, and surrounding areas 24 hours a day, 365 days a year.
Do you charge extra for emergency or after-hours calls?
No. EcoFrost charges $0 in overtime fees. The same honest rate applies at 2 AM on a Sunday as it does on a Tuesday afternoon.
What should I do if my carbon monoxide detector goes off?
Leave the house immediately and call 911 or your gas utility first. Once you're safe, call EcoFrost. We'll inspect and repair your heat exchanger or combustion system as an emergency.
My furnace stopped working overnight - is this dangerous?
In Canadian winters, an unheated home can drop below freezing within hours, risking pipe bursts and health issues. Don't wait until morning - call our 24/7 emergency line immediately.
Can you fix my furnace or AC the same day?
Yes, in most cases. Our technicians carry a wide range of common parts on every truck. Over 90% of emergency repairs are resolved on the first visit.
