What to do if your Furnace is Down?
If your furnace breaks down, it can be inconvenient and uncomfortable, especially during colder months. Here’s a step-by-step guide on what to do if your furnace stops working:
Verify the thermostat: Ensure that it is in “Heat” mode and set to the desired temperature. Sometimes, the issue might be as simple as a thermostat setting.
Check Power Supply: Ensure that the furnace is receiving power. To determine whether the furnace’s circuit has tripped or if a fuse has blown, check the circuit breaker or fuse box.
Reset the Furnace: Some furnaces have a reset button. If you’re comfortable doing so, you can try resetting the furnace by following the manufacturer’s instructions.
Inspect the Pilot Light (Gas Furnace): If you have a gas furnace, check the pilot light. If it’s out, follow the manufacturer’s instructions to relight it. If the pilot light doesn’t stay on, there might be a bigger problem that needs to be fixed by a professional.
Check the Air Filter: A clogged air filter can lead to poor airflow and overheating. Check the filter and replace it if it’s dirty or clogged.
Check for Error Codes: LED displays with error codes are a feature of some contemporary furnaces. Refer to your furnace’s manual to understand what the error codes mean.
Check Gas Supply (Gas Furnace): If you have a gas furnace, make sure the furnace’s gas supply is turned on. Leave your house right away and contact your gas supplier if you think there may be a gas leak.
Inspect Vents and Exhaust: Ensure that air vents and exhaust pipes are clear of debris and snow, especially if your furnace is located outside.
Make a Professional Call: If you’ve tried the above steps and your furnace still isn’t working, it’s time to call a professional HVAC technician. Attempting to fix complex issues on your own can be dangerous and may cause further damage.
Stay Warm: Until the furnace is fixed, stay warm by wearing warm clothing, using blankets, and thinking about using space heaters.
Keep in mind that, particularly when working with gas furnaces, furnace repairs can be challenging and even hazardous. It’s best to leave the diagnosis and repair to trained HVAC technicians. To keep your furnace operating at its best, schedule yearly maintenance checks. Regular maintenance can also help prevent breakdowns.
