24-Hour HVAC Repair Toronto | Emergency Service

Need help right now? Call (416) 835-4775 or visit our 24/7 emergency HVAC service page.

HVAC emergencies do not respect business hours. The coldest nights of a Toronto January are exactly when aging furnaces give up. Heat waves that drive your AC hardest are when compressors fail. Knowing what to expect from 24-hour HVAC service before you need it makes a stressful situation much more manageable.

What Happens When You Call EcoFrost for Emergency HVAC

Call (416) 835-4775 - answered 24/7

A live EcoFrost team member answers your call - not a call centre. We ask about your system, the symptoms, and your address to dispatch the closest available technician.

Technician dispatched with ETA

We provide a realistic arrival window based on current call volume and your location. In Toronto and Mississauga, most emergency calls see a technician within 60 to 90 minutes.

Diagnosis and transparent quote on arrival

Our technician diagnoses the problem, explains the cause in plain language, and provides a written quote before any work begins. No surprise charges.

Repair or temporary solution

Most repairs are completed same-visit. If a part is unavailable, we implement a safe temporary solution and return within 24 hours with the required component.

Follow-up and documentation

You receive a full service report of what was found, what was repaired, and any recommendations for future maintenance. No vague invoices.

Emergency HVAC Pricing in Toronto

EcoFrost charges a flat diagnostic fee that applies toward any repair. There are no overtime surcharges, no after-hours premiums, and no weekend rates. The repair cost depends on what is found, but our technicians provide a complete price before starting any work.

Beware of HVAC companies that charge 1.5x or 2x "after-hours rates." The industry average after-hours call in Toronto can reach $350 to $500 in diagnostic fees alone before any parts. Always ask for a flat-fee diagnostic up front.

Most Common Emergency HVAC Repairs in Toronto

Ignitor failure - most common furnace no-heat call, usually fixed in under an hour
Pressure switch fault - often caused by a blocked condensate drain
Flame sensor dirty or failed - prevents furnace from staying lit
Thermostat failure or dead batteries - always check this first before calling
Capacitor failure in AC - most common summer emergency, usually same-visit repair
Refrigerant leak in AC - can cause complete cooling loss, requires certified tech
Draft motor failure - stops furnace from venting, safety shutdown triggered

What to Do Before the Technician Arrives

Check the thermostat: set to HEAT, temperature set above room temp, new batteries if needed
Check the furnace switch on the wall near the unit - must be ON
Check your electrical panel for a tripped breaker labeled "furnace" or "HVAC"
Check the furnace filter - a completely blocked filter can trigger safety shutdown
For gas smell: do NOT touch switches, leave the home, call Enbridge at 1-866-763-5427

?Frequently Asked Questions

Is there an extra charge for after-hours HVAC service in Toronto?

EcoFrost charges $0 overtime or after-hours fees. Whether you call at 2 PM on a Tuesday or 2 AM on a Sunday, you pay the same diagnostic and repair rates. Many HVAC companies charge 1.5x to 2x rates on evenings and weekends - we believe that is unfair when your family's comfort and safety is at stake.

How quickly can EcoFrost respond to a furnace emergency in Toronto?

Our average emergency response time in Toronto and Mississauga is under 90 minutes. In peak winter periods (January-February), response times can extend to 2 to 3 hours due to high call volume. We always provide a realistic arrival window and call when the technician is 20 minutes away.

What constitutes a true HVAC emergency in Toronto?

A true HVAC emergency requiring immediate service includes: no heat when outdoor temperatures are below 5°C, a gas smell or carbon monoxide alarm, a furnace red-tagged by Enbridge, flooding from a failed humidifier or condensate system, or no cooling during a Toronto Public Health heat alert. For minor issues like uneven heating or strange noises, next-day service is usually appropriate.

Can my furnace be repaired the same night?

Most furnace repairs can be completed on the same visit. EcoFrost technicians carry the most common replacement parts - ignitors, pressure switches, limit switches, flame sensors, capacitors, and control boards. If a specialized part is needed, we can often source it same-day from our supplier network and return within 24 hours.
