3 Signs of a Faulty Furnace Blower Motor in Cary, NC

December 18, 2023

Furnaces use blower motors to move warm air into ductwork and distribute it throughout your home. Since blower motors perform such an important function, homeowners in Cary, NC should watch out for indicators that they might not be working. If you notice any of these three signs, you likely have a faulty furnace blower motor.

1. Poor Heating

The most obvious consequence of a failing blower motor is that your furnace simply doesn’t heat your home. The furnace may be able to generate hot air, but if the blower motor can’t spread it around, this will make no difference to your home’s temperature. Many other things might be behind this particular issue, but a malfunctioning blower motor is certainly one option.

2. Unusually Large Heating Bills

As a consequence of the problem mentioned above, you’ll probably notice increased heating bills. If your furnace can’t move warm air through your ductwork, your thermostat won’t register any temperature changes. As a result, the thermostat will command the system to continue working and force it to consume far more energy than it normally would.

3. Overheating

Without a blower motor to remove warm air from the internal confines of your heating system, your system and its vital components will heat up significantly. If you don’t address this problem, it may do serious damage to your system and can cause any number of other parts to fail. Ultimately, this kind of overheating can destroy your furnace and force you to install a new one.

A broken furnace blower motor can leave you feeling cold this winter and lay the groundwork for some future damage to your heating system. Call Cape Fear Air Conditioning, Heating, & Electrical Company, Inc., and ask about our heating repair services.
