As winter approaches and temperatures drop, having a well-functioning heating system is essential for keeping your home warm and comfortable. But what if you suddenly find your furnace blowing cold air? At Custom Climates HVAC in Auburn, NH, we understand how important it is to have a reliable heating system, and we’re here to help you troubleshoot and resolve this issue. In this blog, we’ll discuss what to do if your furnace is blowing cold air and how to avoid potentially costly furnace repairs in the future.
Check the Thermostat
The first step in troubleshooting a furnace blowing cold air is to check your thermostat. Make sure it’s set to “heat” mode and the temperature is set above the current room temperature. If the thermostat is set correctly and the furnace is still not producing heat, it may be time to call a professional furnace repair service.
Inspect the Air Filter
A dirty or clogged air filter can lead to poor airflow and reduced heating efficiency. Regularly inspect and replace your air filter to ensure optimal furnace performance. If you’re unsure how to do this, consult your owner’s manual or contact a professional heating and cooling systems repairs service for assistance.
Examine the Pilot Light
If you have an older furnace with a pilot light, check to see if it’s lit. If it isn’t, follow the instructions in your owner’s manual to relight it. If the pilot light keeps going out, it may be an indication of a more serious issue, such as a faulty thermocouple or gas valve. In this case, contact a professional furnace repair service to diagnose and fix the problem.
Check the Gas Supply
If your furnace is gas-powered, ensure the gas supply is turned on. If it’s not, turn on the gas valve and see if the furnace starts producing heat. If you suspect a gas leak, do not attempt to fix it yourself – call a professional HVAC service immediately.
Inspect the Circuit Breakers
A tripped circuit breaker could be the cause of your furnace blowing cold air. Check your home’s electrical panel to see if any breakers have tripped. If they have, reset them and see if your furnace starts working properly. If the problem persists, it may be time to call a professional heating and cooling systems repair service.
