Why Doesn’t My Furnace Ever Stop Running in Florence, AL?

Dealing with a furnace that won’t stop running in Florence, AL, is both a nuisance and a strain on your finances. A heating system is an intricate machine that requires many different components to work together to properly heat your home. Here are several common reasons a furnace won’t stop running:

Temperature Is Set Too High

Your furnace will try to heat your home to whatever temperature is set on your thermostat. If that temperature is set too high, your system may constantly run to try and reach that goal.

Dirty Air Filter

A dirty air filter can negatively impact the performance of your heating system by restricting airflow through it. This airflow issue causes your furnace to struggle to maintain your desired temperature. As a result, the heating system won’t stop running.

Malfunctioning Pilot Light

Do you have a gas furnace? The pilot light is the mechanism that ignites the gas supply before reaching the burner.

If your pilot light doesn’t stay lit, your furnace won’t reach its desired temperature, causing it to continuously cycle on and off. Scheduling regular maintenance can help spot pilot light issues before they become a major problem.

Leaks in Ductwork

Leaks can occur anywhere within your ductwork. When a leak is present, the warm air pushed throughout your home by your heating system will escape, while cold outside air will take its place. This results in your home never reaching the temperature set on your thermostat, causing your furnace to continue to run to try and heat your home as intended.

Undersized Furnace

An undersized heating system for the size of your home will have trouble properly warming it. In this scenario, your furnace simply doesn’t have the capacity to reach the target temperature and will strain itself trying to do so.

There are many different reasons a heating system will constantly run, including incorrect temperature settings, dirty air filters, pilot light issues, leaky ductwork and an undersized system for your home. If you’re dealing with a furnace that won’t shut off, contact Price Heating and Air today.
