Finding that your furnace is failing to produce warm air is one of the biggest issues home owners can encounter when it comes to their HVAC system. Your furnace may be running, but blows cold air instead of hot. Or, your furnace may not even turn on at all.
In either case, furnace troubleshooting no heat-related problems is something you’ll want to get fixed fast, especially during the colder months of the year. Read on for our tips on diagnosing and resolving your furnace troubleshooting “no heat” issue:
Furnace Troubleshooting: No Heat
Is your furnace running, but simply not heating? If you find that cold air is coming from your registers instead of warm, your furnace is likely just recirculating the air within your home without heating it up first. Run through the following checklist first to see if any of these problems are the culprit:
- Is your thermostat set to heating? Try raising the temperature a few degrees and see if the furnace starts blowing warm air.
- Are your registers open? Make sure they are open and not blocked by furniture.
- Is the breaker that controls your furnace tripped? If so, reset the breaker.
- Is your furnace filter dirty? Clean or replace the air filter.
- Is the pilot light out? Re-light it if you are comfortable doing so. If not, call your local HVAC company for help.
Once you’ve double-checked all of these potential issues and ruled each of them out, it’s likely time to call in a professional. Further fixes and repairs can be dangerous and should only be performed by an experienced HVAC technician.
Furnace Troubleshooting: Furnace Won’t Turn On
You might find that not only is your furnace not heating, it is not turning on at all. If this is the case, start by making sure the furnace is set to “ON” and its breaker is not tripped. You’ll also want to check that the condensate pan is not full, and that the furnace’s air filter is clean – both of these issues may result in your furnace not turning on. If after checking all of these areas your furnace is still not turning on and blowing hot air, turn to a professional for assistance with troubleshooting.
