Freezing temperatures won’t roll in until January for Southeastern North Carolina residents. But don’t wait until then to check if your furnace is operating smoothly.
Especially if you notice your furnace blasting cold air, start troubleshooting now.
To determine if the issue is something you can fix yourself or if it’s time to get your furnace serviced, here’s a quick checklist to help you out.
Inspect Your Furnace Air Filter
A clogged air filter blocks airflow through your furnace, raising the temperature inside of it. This blockage can cause your furnace to overheat and the furnace burner to shut off.
Do this: Locate the air filter in your furnace. Slide out your old filter and throw it out if it’s dirty. Then, insert a new filter that matches the size of your unit. Position it in the right direction according to your filter frame. Also, consider a reusable air filter like the Trane CleanEffects air filter.
Test Your Flame Sensor
A flame sensor is a crucial safety part of any furnace system. A flame sensor that isn’t working correctly or covered with grime can cause your burner to keep shutting off.
Do this: Call your HVAC professional to inspect.
Check Your Thermostat
Your thermostat tells your furnace your home temperature needs. So, if your thermostat isn’t working accurately, it can’t communicate the right instructions to your furnace.
Do this: Call an HVAC technician to inspect your thermostat. If you need a replacement, upgrade to a smart thermostat. These programmable units will give you better temperature control and energy efficiency.
Look for Leaking Ducks
It may be time to check for leaking ducks if you have a furnace blowing cold air when the heat is on. Leaks in your furnace ducts cause heat energy to escape, so when the heated air reaches your living areas, it becomes cold.
Do this: Call your HVAC professional for service.
Assess Your Pilot Light
If you have an older furnace that’s blowing cold air, your pilot light may have gone out. If you feel comfortable taking steps to relight your pilot light, you may be able to fix this one on your own.
Do this: If you can’t relight your pilot light, call your HVAC technician to ensure it’s properly lit.
