Blower Motor Problems: What They Mean for Your Furnace and Comfort

When Omaha temperatures dip, your furnace works overtime to keep your home warm and comfortable. At the heart of that system is the blower motor — the component responsible for pushing heated air through your ducts and into every room. If the blower motor isn’t working properly, your home may feel unevenly heated, less comfortable, and your energy bills can rise.

So, how do you know if your blower motor is struggling? Here are the most common signs and what they mean:

1. Weak or Uneven Airflow

If some rooms in your home are warm while others remain chilly, your blower motor could be slowing down or blocked by dust and debris. Even a thin layer of dirt on the motor can reduce efficiency, forcing the system to work harder than it should.

2. Strange Noises

A blower motor that’s out of balance or has worn bearings can make loud squealing, rattling, or banging sounds. These noises may start small but typically worsen over time — leading to bigger repairs if left unchecked.

3. Furnace Shuts Off Unexpectedly

A blower motor that overheats may cause your furnace to shut down for safety. This often happens when airflow is restricted, or the motor is running harder than it’s designed to.

4. Rising Energy Bills

Because the blower motor pushes air through the entire system, a struggling motor can cause your furnace to use more energy just to maintain normal comfort. That extra strain adds up fast on your utility bills.
