Troubleshoot Your Malfunctioning Furnace

malfunctioning-furnace-troubleshootThe South-Central area of Texas isn’t exactly known for bitterly cold temperatures, particularly when you compare the area to other states throughout the country. Our evenings, however, are nothing to scoff at when the heating season comes, and as such it’s vital that we have efficient and effective heaters in our homes. But what if you have a San Antonio, TX furnace, and it’s not up to snuff?

Whether you hear odd noises coming from your heating system, detect a strange odor, or simply find that your furnace isn’t performing as well as it once did, there is no problem too big or too small for our team—and no problem that you should just simply ignore. Dealing with furnace and heating problems can be a hassle, but it doesn’t have to be a chore when you count on licensed professionals to handle your heating repairs. In the meantime, we’ve shared with you below some of the most common furnace problems we get calls for.

Unexpected Breakdowns

The most common reason for a premature heating system breakdown is lack of maintenance. Your maintenance appointments allow our team to thoroughly clean and inspect your system, making any adjustments and repair recommendations that we see necessary, allowing you to address the issues right away.

Heating maintenance is typically best scheduled before the heating season begins—before you will need your furnace the most—but what’s more important is that you are investing in this service on at least an annual basis.

Reduced Airflow

The very first thing you should to do troubleshoot this problem is to check your air filter. There is a filter that comes standard with your furnace installation, and its purpose is to protect the inside components of your heater from dirt, dust, and other debris that can begin to wear down its components by making it work harder to do its job.

What’s more, however, is that if this filter becomes too clogged, it will restrict airflow and you won’t get the intended heat in your home. It’s best to change your air filter every 1-3 months, depending on the quality of the filter and the level of airborne contaminants in your home.

No Hot Air

Perhaps the airflow is fine but the air coming out of your vents isn’t as warm as it should be. First, make sure that if you have a programmable thermostat, it is in heating mode and actually set to your desired temperature. It may have been accidentally adjusted by a family member.

Or the problem could be with a miscalibration in the thermostat, in which case the thermostat would need to be repaired or replaced—but at least this would mean that you don’t have anything actually wrong with the heating system!

Furnace Won’t Start Up at All

Does your furnace have a standing pilot light? This is a continuously burning flame that’s used to light the burner, and subsequently start the furnace. If this light is out, then the furnace has no way to start. Some furnaces have a window into the unit where you can see the pilot light. Otherwise, you may have to look under the system. If you do not see the pilot light, then it is out and this is why your furnace won’t start.
