From simple fixes to comprehensive repairs or even replacement, there may be many reasons why your furnace is not heating. There could be a problem with the heat registers or the thermostat. You may have a blown fuse, or the furnace may simply be old and in need of replacing.
Whatever the reason, if your furnace is not heating and you’ve checked the basics listed below, call Ambient Edge at (702) 948-7201 for help.
Troubleshooting Your Furnace
There is never a good time for your furnace to be malfunctioning, so the moment you notice yours is not working properly, run through this basic checklist. If it’s an easy fix, congratulations! You’ll have heat again. If your furnace is still not working, it’s time to call in the Ambient Edge experts.
If one or more rooms in your home feels cold, but the furnace looks, feels, and sounds like it is turning on, the problem may be your heat registers. Make sure all registers are open, wait several minutes, and check the registers continuously to see if any warm air is blowing through them. You can also check the thermostat to see if the temperature is rising.
If the registers are all open, but you are still having issues with your furnace, check your thermostat. The thermostat setting should be on heat and the fan set to auto. Increase the temperature to make sure your furnace will turn on. A thermostat with low batteries or poor wiring may also not be communicating properly with your HVAC system.
Fuses or Breakers
We get a lot of panicked calls from people wondering why their furnace isn’t heating. Often the solution is simply to check the circuit breaker or fuse and make sure power is getting to the furnace in the first place. The electrical switch on your furnace must also be set to on.
Some furnaces have a reset button. Push the reset button. If the furnace starts working properly again, keep an eye on it. If your furnace is continually shutting down and requiring a reset, there may be other, bigger issues at play.
Check your furnace’s filters. If they are dirty and caked with dust, it’s well past time to change the filter. Depending on the type and thickness of your furnace filter, it is recommended you change the filter at least every other month or once every three months.
If air cannot flow through your furnace filter properly (or at all), the furnace can overheat and shut down. Simply replacing your furnace filter with a clean one could be the solution.
If you have any items stacked around or near the furnace, move them to create an unblocked area. Clear space around your furnace helps alleviate fire hazards but also allows for proper airflow.
Also, make sure any doors or panels on the furnace are properly closed. Some furnace models won’t work correctly if there are loose or open doors or panels.
If your furnace is an older model with a pilot light that continuously remains lit, check to see if the pilot is on. If the light appears to be extinguished, follow your furnace manual instructions on how to safely and properly attempt to relight the pilot.
If you notice the pilot light has gone out and you’re not comfortable relighting it on your own, call Ambient Edge at (702) 948-7201 and we can help.
Check to see that the switch to the main gas line is in the on position. If the gas has been turned off for your entire home, it will certainly affect the functioning of your furnace.
Ambient Edge Can Help with the More Serious Furnace Issues
If you have an older furnace, it may have reached the end of its life or is coming close to being obsolete. Older furnaces are only 50 to 70% efficient, according to the U.S. Energy Department. If your older furnace needs to be replaced, your home could be much more comfortable and your energy bills lower when you upgrade to a new model.
If you already have a newer furnace, electronics or digital equipment may need repair.
More serious, but common, furnace issues include:
- Issues with a malfunctioning or broken heat exchanger
- Inoperable blower capacitor
- Dirty or burned out inducer draft motor
- Not enough refrigerant
- Worn out heat pump or starter
- Issues with the pilot or ignitor
