Your furnace’s blower motor sends conditioned air through your ducts and out into the rooms of your house. Without it, you won’t get any warm air to keep you comfortable. Read on to find out some ways you can tell if you have a bad blower motor in the furnace at your home in Hoover, AL.
Low Airflow
In most instances, if your furnace’s blower motor is bad, you’ll get weak or intermittent air flow. Sometimes, the airflow will stop completely. Repairing a blower motor takes an expert, so don’t try to fix this yourself.
Startling Noises
A healthy blower motor will whir and/or hum when your furnace starts up. If the blower motor shrieks or thumps, then something is seriously wrong. The same applies if you hear loud grinding or scraping from the indoor unit.
Unexplained Energy Bill Spikes
When a furnace’s blower motor malfunctions, even if the furnace still works, the system will lose efficiency and work harder to achieve your desired temperature. This will cause your energy bill to rise sharply. Sometimes, if you have a modern variable-speed blower motor, it will stick at a higher speed, producing the same kind of energy bill spike.
A Burning Smell
Sometimes, your furnace’s blower motor will rub against its housing without excessive noise. When you have a burning smell from the registers but don’t see smoke, that could indicate excessive friction within the heating system, creating that burning smell.
The Breaker Trips
Many things can cause a breaker to trip. One of them is a blower motor that has to work too hard and winds up drawing too much power.
