There’s nothing more stressful than waking up to a freezing home on a winter morning in Oshawa—especially when your furnace has unexpectedly stopped working. With temperatures dropping quickly, you can’t afford to wait too long. Knowing what to do in this situation can help you stay safe, minimize discomfort, and avoid costly damage.
In this guide, we’ll walk you through the steps to take when your heating system fails and explain how expert furnace repair Oshawa from trusted companies like Cool Breath HVAC can get your home warm again—fast and affordably.
1. Check the Thermostat First
Before assuming the worst, start with the simplest possible issue—your thermostat. Sometimes, incorrect settings or low batteries can cause your furnace to stop responding. Make sure the thermostat is:
- Set to “Heat”
- The temperature is set higher than the current room temperature
- Functioning with working batteries (if applicable)
Also, confirm that the thermostat screen is on. If it’s blank, try replacing the batteries or resetting the unit.
2. Inspect the Circuit Breaker
Next, head to your home’s electrical panel and check if the circuit breaker that controls the furnace has tripped. If it has, flip it back to the ON position. A tripped breaker may be a one-time glitch—but if it happens frequently, it could signal a larger electrical issue requiring professional inspection.
3. Look at the Furnace Switch and Filter
Most furnaces have a power switch that looks like a regular light switch. Ensure that this switch is turned on. It’s often located near the unit or on the wall beside it.
Also, check your air filter. A dirty or clogged filter can restrict airflow, causing the furnace to overheat and shut down as a safety precaution. If the filter is dirty, replace it immediately.
Regularly changing the air filter is one of the easiest ways to prevent many common furnace issues—something Cool Breath HVAC technicians often find during service calls.
4. Listen and Observe
Pay attention to any strange noises, blinking lights on the furnace, or odd smells. For example:
- A blinking red light could indicate a system error.
- Rattling or banging noises may point to loose parts or motor issues.
- A burning smell might be a clogged filter or worse, electrical overheating.
These signs provide important clues that you can share with your technician if you need to call for furnace repair in Oshawa.
5. Try Resetting the Furnace (If Safe)
Some furnaces have a reset button, typically located on the blower motor. Pressing it can sometimes restart the system if the issue is minor. However, only do this once. Repeated resets can worsen the issue or damage the system.
If you’re unsure whether it’s safe to reset, it’s better to wait for a professional technician from Cool Breath HVAC to evaluate the system.

- Layer up with warm clothing and blankets.
