If your furnace has stopped working, your first thought might be to call a heating contractor to make repairs. However, sometimes there are some minor problems that you can take care of yourself. Here are some things to try before calling out a contractor to fix your furnace.
Look at Your Circuit Breaker
It is only natural to think that if your furnace no longer works, there is something wrong with your furnace. However, there could be a problem elsewhere. Before heading to your furnace to find out what might be wrong, look at the circuit breaker to ensure that power is going to your furnace.
If you find that the breaker has been tripped, flip it back on again. If the breaker trips one more time, there may be an electrical issue that needs to be examined by a professional electrician.
Investigate the Thermostat
Another thing to try before you call a heating contractor is checking at your thermostat. A lot of people skip this step because they don't think something so simple could be the problem--even though it could be. You might simply need to replace the batteries in your thermostat to get it working again.
If you are sure the batteries are fine, be sure your thermostat is set to "heat." If your furnace still doesn't respond, turn the fan switch to the "on" setting. If there is still no change, you will know the problem is definitely with the furnace itself.
Look at the Blower and the Filter
Even if your furnace does power up, it might not heat your home properly and you may start to wonder whether you need to replace it. This might not be the case; you might have a clogged blower or filter.
To find out if this is the case, open the blower panel and take a look. You may see dirt, lint and other debris clogging up the blower. You can fix this by turning off your furnace and using your vacuum's handheld attachment to suck all the debris out of the blower.
Next, look at the filter. Pull out the filter and make sure there are no tears in it and to get all the dust off of it. To do this, use an old toothbrush to brush all the dust and dirt off of the filter before putting it back into the panel. If the filter is too dirty, you might opt to replace it by purchasing a new one at any home improvement store.
Once you have checked both the blower and the filter, be sure that you shut the blower panel completely; some furnaces come with a safety measure which will not allow the furnace to turn on again until the panel is closed properly.
Make sure you use the information laid out above to get to the bottom of your furnace problems. If you still have furnace trouble, call a heating contractor like Butler Heating & Air who can make necessary repairs. They will be able to more quickly determine the problem once you tell them what you have tried already.
