The short answer: for emergency furnace repair in Ajax, call a TSSA licensed heating company that runs a real 24 hour line, and treat a suspected gas leak or a carbon monoxide alarm as a 911 emergency first. A furnace that fails in extreme cold is urgent, especially for young children, older adults, and anyone with health conditions, so it warrants a same-day or overnight response rather than a next-week appointment.
Aire One East is a Carrier Factory Authorized dealer serving Ajax and Durham Region since 1991, with TSSA certified technicians, Licence #1219734, a 4.8 star rating across 364 Google reviews, and 24/7 emergency service. If your furnace is down now, call 905-576-7600.
Who to call, and when to call 911 first
For a furnace that has simply stopped heating, call a licensed heating company with a genuine 24/7 emergency line, such as Aire One East at 905-576-7600. But safety comes before the repair, so there are two situations where you call 911 or your gas utility first.
Once everyone is safe and there is no gas or carbon monoxide concern, an unheated furnace is a heating emergency that a 24/7 company can handle.
What counts as a furnace emergency
Not every furnace issue needs a midnight call, so here is how to judge. Treat it as an emergency, worth calling right away, when any of these is true.
- No heat in extreme cold, especially overnight or with young children, older adults, or anyone with a health condition in the home.
- A carbon monoxide alarm, which is always a 911 emergency first, as above.
- A gas smell, also a leave-and-call emergency before anything else.
- Burning or electrical smells, or visible smoke from the furnace, which means shutting it off and calling.
- Water pooling or ice around a high-efficiency furnace that has stopped, which can signal a blocked vent.
A furnace that is merely noisy, short cycling, or weak but still producing heat is usually a next-day service call rather than a midnight one, though it should still be booked promptly.
What to do safely while you wait
While a technician is on the way, keep the household safe and warm without creating a bigger hazard. The safe steps are simple.
- Keep everyone in one room and close doors to unused areas to hold heat in a smaller space.
- Layer up with warm clothing, blankets, and hats, and give extra attention to infants and older adults.
- Use only safe heat sources. A properly working portable electric heater with an automatic tip-over shut-off is fine, kept clear of anything flammable.
- Never use a gas oven, stove, barbecue, or any unvented fuel-burning heater indoors for warmth, because these produce carbon monoxide and are a genuine risk to life.
- Keep taps dripping in extreme cold to reduce the chance of frozen pipes if the outage runs long.
- If it becomes dangerously cold, consider staying with family or a neighbour until heat is restored.
Quick checks that sometimes restore heat
Before the technician arrives, two safe checks occasionally solve the problem at no cost. Try the thermostat first, confirming it is set to heat, above room temperature, with good batteries. Then check that the furnace breaker and the switch on or beside the unit are on, and that the furnace door panel is fully seated, since a safety switch stops the furnace if it is open. Replacing a badly clogged filter is also worth a try. If none of that restores heat, stop there, because anything involving the burner, gas, or venting is licensed work.
