Furnace Blower Motors, On the Shelf All Winter

When the blower quits in January, you don't have a week to wait on a part. We stock furnace blower motors and draft inducers for every major system, matched and wired at the counter.

Built for St. Louis Winters

A Blower Motor Replacement That Outlasts the Old One

Your furnace fan motor moves every bit of heated air in the building. When it fails, the furnace runs but the house stays cold, and the repair clock starts ticking.

Our furnace blower motors are built to handle the hardest St. Louis winters and double as efficient air movers for summer cooling. They're designed to maximize airflow while minimizing energy use, which shows up on your utility bill.

Whether you're swapping a failed motor or doing a full system overhaul, our staff matches the exact replacement, by horsepower, frame, RPM, and rotation, and offers honest advice on getting the most from your furnace year-round. Bring the old motor or the furnace model number and we'll handle the rest.

Questions

Frequently Asked Questions

How much does furnace blower motor replacement cost?
The motor itself typically runs well under what an HVAC service call charges for the same part installed. Standard PSC blower motors are the most affordable; variable-speed ECM motors cost more. Call with your furnace model and we'll quote the exact motor.
How do I know my furnace blower motor is failing?
Humming with no airflow, screeching or grinding, weak airflow, frequent cycling, or a furnace that runs but doesn't move air. Any of these means test the motor and capacitor before the cold snap does it for you.
Can I replace a furnace blower motor myself?
Many of our customers do. If you can match the specs and handle basic wiring, it's a manageable job, and we configure the wiring for your application before the motor leaves the counter.
Do you stock motors for older furnaces?
Yes. Hard-to-find and legacy furnace motors are our specialty. If the exact unit no longer exists, we'll cross-reference a compatible modern replacement.
