24 Hour Emergency HVAC Repair in Toronto: What to Do When Your System Fails
It is 2 AM. The temperature outside is -18 degrees Celsius. Your furnace just stopped working. The house is getting cold fast, your kids are shivering, and you need help now -- not tomorrow morning, not during business hours. Right now.
Or maybe it is the middle of a July heat wave. Environment Canada has issued a heat warning. Your air conditioner quit and the indoor temperature is climbing past 30 degrees. You have elderly family members at home. This is not a comfort issue. It is a safety issue.
If you are reading this in the middle of an HVAC emergency, here is the most important thing on this page: call (647) 852-2359 right now. Imperial Heating provides 24 hour emergency HVAC repair across Toronto and the entire GTA. No overtime charges. We aim to be at your door within 2 hours.
If you have a moment to read, this guide covers everything you need to know about handling an HVAC emergency in Toronto -- what to do first, what qualifies as a true emergency, and how our 24/7 emergency service works.
What Qualifies as an HVAC Emergency?
Not every HVAC problem is an emergency. A furnace making a new noise or an AC that is not cooling quite as well as last summer -- those are important, but they can wait for a scheduled appointment. A true HVAC emergency is a situation where your safety, health, or property is at immediate risk.
These are HVAC emergencies -- call immediately:
- No heat in winter when temperatures are below freezing. Without heat, pipes can freeze and burst within hours, causing thousands of dollars in water damage. Infants, elderly, and anyone with health conditions are at risk of hypothermia.
- No cooling during a heat warning or extreme heat event. Heat stroke and heat exhaustion are serious medical emergencies. If indoor temperatures exceed 30 degrees Celsius and you cannot cool the space, especially with vulnerable people at home, this is an emergency.
- Gas leak or strong gas smell. If you smell natural gas (rotten egg smell) near your furnace, leave the house immediately. Do not flip light switches, use your phone inside, or start your car in the garage. Get everyone out, then call 911 and your gas company (Enbridge: 1-866-763-5427) from outside. Once the area is declared safe, call us to inspect and repair the furnace.
- Carbon monoxide alarm sounding. A CO alarm going off while your furnace is running means your system may have a cracked heat exchanger or venting problem. Get everyone out of the house immediately and call 911. Carbon monoxide is odourless and lethal. After emergency services clear the home, call (647) 852-2359 for furnace inspection.
- Water leaking from your HVAC system. A furnace or AC unit actively leaking water can cause structural damage, mould growth, and electrical hazards. A leaking water heater or boiler can flood your basement. This needs same-day or emergency service depending on the volume of water.
- Electrical burning smell from your HVAC system. If you smell burning plastic or electrical burning coming from your furnace or AC, shut the system off at the thermostat and the breaker immediately. Do not restart it. This could indicate an electrical short, overheating motor, or wiring failure -- all fire hazards.
Step-by-Step: What to Do During a Furnace Emergency
If your furnace fails in the middle of a Toronto winter, follow these steps in order:
Step 1: Check the obvious. Before you panic, verify the basics. Is the thermostat set to heat and turned up? Is the furnace switch on (the light switch on or near the furnace)? Has the circuit breaker tripped? Is the furnace filter completely clogged? Sometimes the fix is a flipped switch or a $5 filter. Check these first -- it takes 2 minutes.
Step 2: Check for gas smell. If you smell gas at all, stop everything else. Do not touch the furnace. Get everyone out of the house and call 911 from outside. Then call Enbridge at 1-866-763-5427. Do not re-enter the house until emergency services say it is safe.
Step 3: Check your CO detectors. Make sure your carbon monoxide detectors are working. If they are alarming, evacuate immediately and call 911. If they are not alarming but you feel dizzy, nauseous, or have a headache, evacuate anyway -- your CO detector may be malfunctioning.
Step 4: Call Imperial Heating at (647) 852-2359. Once you have confirmed there is no gas leak or CO emergency, call us for 24 hour emergency furnace repair. Tell the dispatcher your situation -- no heat, the current indoor temperature, and whether anyone vulnerable (elderly, infants, medical conditions) is in the home. This helps us prioritize.
Step 5: Protect your home while you wait. Close curtains and blinds to insulate windows. Close doors to unused rooms to concentrate heat in occupied areas. Use space heaters if you have them, but keep them away from curtains, furniture, and bedding. Layer up with blankets and warm clothing. If the temperature drops below 10 degrees indoors, open a tap to a slow drip to prevent pipes from freezing.
Step 6: Do not attempt DIY furnace repair. We understand the temptation to try to fix it yourself. But furnaces involve natural gas, high voltage electricity, and combustion. An incorrect repair can cause a gas leak, electrical fire, or carbon monoxide poisoning. Wait for a licensed technician.
Step-by-Step: What to Do During an AC Emergency
A failed air conditioner during a Toronto heat wave is more than uncomfortable -- it can be dangerous. Here is what to do:
Step 1: Check the basics. Is the thermostat set to cool? Is the outdoor unit running? Has the breaker tripped? Is the filter clean? Sometimes the fix is simple.
Step 2: Assess the health risk. Check on elderly family members, infants, and anyone with heart conditions or respiratory issues. Heat exhaustion symptoms include heavy sweating, weakness, cold and clammy skin, nausea, and fainting. Heat stroke symptoms include high body temperature (above 39.4 degrees Celsius), hot and dry skin, rapid pulse, and confusion. Heat stroke is a medical emergency -- call 911 immediately.
Step 3: Call (647) 852-2359 for 24 hour emergency AC repair. Describe the situation and we will dispatch a technician to your Toronto home.
Step 4: Cool down while you wait. Close blinds on sun-facing windows. Use fans to circulate air. Apply cold wet towels to your neck and wrists. Drink cold water consistently. If the indoor temperature is dangerously high and you have vulnerable people at home, consider going to a cooling centre or a neighbour's air-conditioned home temporarily.
Step 5: Do not run the system if it is making unusual noises or smells. If your AC is making grinding, screeching, or banging noises, or if you smell electrical burning, turn it off at the thermostat and breaker. Running a failing compressor or motor can cause further damage and increase the repair cost.
How Fast Is 24 Hour Emergency HVAC Repair in Toronto?
When you call Imperial Heating for emergency HVAC repair, our goal is to have a licensed technician at your door within 2 hours. For most locations across Toronto and the GTA, we meet or beat that target.
Our response time depends on several factors:
- Time of call: We staff technicians around the clock, including weekends and holidays. A 3 AM call gets the same priority as a 3 PM call.
- Your location: Central Toronto locations typically see faster response. Outer GTA areas like Bowmanville, Bolton, or Uxbridge may take slightly longer but are still covered under our 24 hour service.
- Severity: No heat in winter with vulnerable occupants and gas leak situations are dispatched immediately. A noise concern at 11 PM may be scheduled for first thing the next morning.
- Demand: During extreme cold snaps in January and heat waves in July, call volume spikes. Call early in the event if you notice your system struggling -- do not wait until it fails completely.
We carry common replacement parts on our trucks -- ignitors, flame sensors, capacitors, contactors, blower motors, and control boards -- so most emergency repairs are completed in a single visit.

What to Expect During an Emergency HVAC Service Call
Knowing what to expect reduces stress during an already stressful situation. Here is how our 24 hour emergency HVAC repair process works:
1. You call (647) 852-2359. Our dispatcher picks up -- not a voicemail, not a call centre overseas. You speak to someone who can help you right now. Describe your situation and we will give you an estimated arrival time.
2. A licensed technician arrives. Our technicians arrive in fully stocked service vehicles. They carry ID and will introduce themselves. They wear shoe covers to protect your floors.
3. Diagnosis first. The technician inspects your system, identifies the problem, and explains what failed and why. You get a clear explanation in plain language, not technical jargon.
4. Upfront pricing before any work begins. You get the total cost of the repair before the technician starts. No surprises. No hidden fees. If the repair is not worth the cost (for example, if it is an old system and a major component failed), we will tell you honestly and discuss your options, including furnace replacement or a heat pump upgrade.
5. No overtime charges. This is important. Many HVAC companies charge time-and-a-half or double rates for nights, weekends, and holidays. Imperial Heating does not charge overtime. The price you are quoted at 2 AM on a Saturday is the same price you would pay at 2 PM on a Tuesday. 24 hour emergency HVAC repair should not come with a penalty for having an emergency at an inconvenient time.
6. Repair completed. Most emergency repairs are completed in 1 to 2 hours. The technician tests the system, confirms it is running correctly, and makes sure you are comfortable before leaving.

How to Prevent HVAC Emergencies
The best emergency is the one that never happens. Most HVAC emergencies are preventable with basic maintenance. Here is what you can do to keep your system running reliably:
Schedule annual professional maintenance. Have your furnace inspected and tuned up every fall before heating season. Have your AC serviced every spring before cooling season. A professional maintenance visit catches failing components before they fail completely -- a $150 maintenance visit can prevent a $500 emergency repair at 2 AM.
Change your filter regularly. A clogged filter is the number one cause of preventable HVAC failures. It restricts airflow, causes the system to overheat, and puts stress on the blower motor. Check your filter monthly and replace it every 1 to 3 months depending on the filter type and whether you have pets.
Listen to your system. New noises, unusual smells, uneven heating, and rising energy bills are your furnace or AC telling you something is wrong. Do not ignore these signs. A $200 repair during business hours is better than a $500 emergency repair at midnight.
Keep vents and registers clear. Blocked vents cause pressure imbalances that strain your system. Make sure furniture, curtains, and rugs are not covering supply or return vents.
Test your system before the season. Turn on your furnace in early October before you actually need it. Turn on your AC in late April. If something is wrong, you have time to schedule a non-emergency repair instead of discovering the problem during the first cold snap or heat wave.
Install and maintain CO detectors. Ontario law requires carbon monoxide detectors on every floor of your home if you have a fuel-burning appliance. Test them monthly and replace batteries annually. Replace the detector itself every 7 years.
