How Much Does an AC Unit Fan Motor Cost? [2025 Data]

HVAC Pro Costs

Hiring a certified AC technician makes up 50% of the total AC unit fan motor replacement cost. Homeowners can expect to spend $50 to $250 for an initial service fee for a pro to diagnose the problem, plus $100 to $250 per hour for labor, with the replacement taking one to four hours. 

Here’s what you can expect to spend for the replacement and related services:

• Initial HVAC repair service fee: $50–$250

• Part replacement: $60–$250

• HVAC inspection: $70–$500

• AC cleaning: $100–$400

Fan Motor Quality

When replacing the AC unit’s fan motor, you can choose one from the original equipment manufacturer (OEM) or an off-brand (non-OEM) part. OEM parts have several benefits, including maintaining your HVAC’s warranty and a guarantee that they work with your system. However, OEM parts do come at a higher cost. 

Ask your HVAC pro if they carry OEM parts and what they’d recommend for your system. On average, you could pay 50% more for an OEM part. However, they often have longer life spans because of their proven compatibility with your system, so they’re worth the extra cost. 

Additional Cost Factors

Aside from OEM parts and labor costs, the total price to replace an AC unit fan motor depends heavily on whether your unit is under warranty and if the repair is an emergency service or not. Here are some factors that can affect the project total.

Warranties

Warranty coverage can mean the difference between paying less than $100 for a new AC unit fan motor and paying $700 or more for the same part. 

Either the AC warranty, which lasts five to 10 years on average for individual parts, or your home warranty may cover the cost of an AC unit fan motor. A home warranty costs $230 to $1,900 per year, but it could save you money on household upkeep and repairs.

Accessibility

The more difficult it is to access your AC unit’s fan motor, the higher the cost to replace the motor will be. Most exterior AC units will be located near the house in an easily accessible space, but if you have shrubs growing around the units or other obstructions, you may need to pay up to $700.

Emergency Repair Costs

It’s 92 degrees outside, you have guests coming for dinner, and suddenly, your AC stops working. If you need the AC unit fan replaced quickly or during off-hours, expect to spend an extra $40 to $80 per hour for labor, totaling around $190 to $330 per hour plus the cost of parts.

Additional Repairs

The blower, sometimes called a blower fan, is located on the inside unit and can also wear down over time. If you notice furnace problems like a lack of airflow in the house, it may be time to replace the blower. A new blower motor costs $560.

If the AC unit fan stops working and overheats the system, you may also need to replace a contactor. Replacing the AC contactor costs $150 to $350.

DIY AC Unit Fan Motor Replacement vs. Hiring a Pro

Unless you have previous experience in AC installation and repair, leave this job to a certified pro. Replacing the AC unit fan motor requires handling potentially sharp blades and working near the condenser coil, which contains refrigerant. Exposure to refrigerant poses health hazards, including vomiting, skin irritation, and respiratory diseases, so always leave repairs on the exterior AC unit to a trained AC installer near you.

AC Unit Fan Motor Replacement vs. Repair 

When your AC unit fan motor fails, you may consider whether to repair the part or replace it. A faulty fan motor can also make you consider whether to replace your air conditioner altogether. Consider the following factors when deciding whether to repair the fan motor, replace it, or install a new AC.

• Warranty: If your AC unit is still under warranty, the warranty may cover the replacement cost for the fan, although you’ll still need to pay out of pocket for labor fees. 

• Part lifespan: An AC unit fan should last 10–15 years. If your motor breaks down sooner, have a pro determine if the part can be repaired before paying for a replacement.

• AC system lifespan: An AC system lasts 10–20 years, so if your system is older, it may be better to replace it entirely when a part stops working.

• 50% rule: If your AC repairs, including replacing the fan, total more than 50% of the cost of a new system, it’s a better investment to upgrade your HVAC entirely.

How to Save Money on a New AC Unit Fan Motor

When the AC fan motor wears out, it can be an unexpected hit to your wallet. But leaving it as-is while still running the AC can lead to costly energy bills or an overheated system that stops working when you need it. In fact, a worn-out motor can cause the compressor to overheat, and an AC compressor costs $800 to $2,300 to replace.

In order to budget for this repair, consider these tips to reduce AC unit fan motor costs:

• Check the warranty: If your HVAC is under warranty or you have a home warranty, you may save on the cost of replacement parts.

• Look for off-season deals: AC repairs are common in summer, so repair shops may offer deals when demand is lower in fall and winter. Get your HVAC serviced twice per year so that you can avoid peak-season emergency repairs. 

• Consider OEM parts: While non-OEM parts may cost less up front, they can void your warranty.

Does a New AC Unit Fan Motor Increase Home Value?

An HVAC system adds value to your home as long as it’s either new or in excellent working condition. By replacing the AC unit fan and keeping up with regular maintenance, your HVAC system could add 5% to 7% value to your home compared to if you had a poorly working system or no system at all.
