When one fails or starts to fail, energy consumption climbs and repair bills follow. We handle all three answers to that problem. **Repair.** Our technicians diagnose and repair AC motor issues with state-of-the-art tools, fast, because a dead blower in a St. Louis summer is an emergency, not an appointment. **Replacement.** When a motor is beyond repair, we match a replacement to your unit and budget from the Midwest's largest stock. Most AC motor replacement orders ship same day. **Maintenance.** Annual motor service reduces energy use and extends the life of the whole unit. Cheaper than a July breakdown.

Counter service Questions ## Frequently Asked Questions How much does AC motor repair cost? Most air conditioning motor repairs run $150 to $450, depending on the motor type and extent of damage. Labor, parts, and diagnostic fees affect the final number. Call us with your motor details for a real estimate before you commit to anything. What does an AC fan motor replacement cost? A condenser fan motor or blower motor replacement typically runs $300 to $600 for parts and labor. Complex ECM motors cost more than standard PSC motors. Buying the motor from us and installing it yourself cuts that substantially. What's the difference between single-phase and three-phase AC motors? Single-phase motors run residential AC units on standard household power. Three-phase motors power commercial and industrial systems with greater durability and output. We stock both. Why is my AC motor making noise? Unusual noise usually means worn bearings, loose parts, or debris in the housing. Noise is an early warning. Getting it inspected before failure is the difference between a small repair and a dead system. Can an AC motor be repaired, or does it always need replacement? Depends on severity and age. Worn bearings are repairable. Major failures in older motors usually make replacement the smarter buy, and modern replacements are often more efficient. We'll tell you which honestly. We make money either way, so we have no reason to upsell. ## Motor Down? Pick It Up Today or We'll Ship It Today.
