Replacing your AC fan motor costs $500 on average, with most homeowners paying between $100 and $700. Costs could go as low as $60 or as high as $1,200, depending on your warranty. The condenser fan motor in your AC prevents the compressor from overheating by cooling the refrigerant that moves through the system. Factors like motor size, labor, and the quality of your unit all influence the cost.
Regular maintenance can help you avoid this repair, and if your system is under warranty, you'll only need to pay for labor. Hiring a professional is key to safely and correctly completing this project.
Condenser Fan Motor Replacement Cost Factors
Several factors influence the cost of replacing the fan motor for your AC unit, such as when you schedule the repair, the type of parts you choose, diagnostic fees, and whether you have a maintenance plan. Here's what you need to know about each cost factor.
Condenser Fan Motor Prices
AC fan motors cost anywhere from $60 to $250 for the part alone, but you'll only pay for labor and the initial service fee if your unit is covered under warranty. In other words, if your part is covered, you can subtract the cost of the motor from your total project budget to see how much you'll pay.
Brand
The cost of a new AC condenser fan motor can depend on the brand of your unit. Here's what you can expect to pay for fan motors from some of the most popular HVAC brands:
| AC Fan Motor Brand | Average Price Range |
|---|---|
| Carrier | $100–$800 |
| Comfortmaker | $140–$500 |
| Goodman | $70–$350 |
| Lennox | $150–$700 |
| Rheem | $200–$500 |
| Trane | $180–$700 |
| York | $140–$300 |
Labor
Labor costs for replacing your AC fan motor range from $100 to $250 per hour, and the job takes one to four hours. When hiring an HVAC technician, ask whether they charge by the hour or offer a flat fee for the service.
Season
AC systems are more likely to break down when overworked, which tends to happen during the warmer months. AC repair pros near you will be in high demand during the summer, especially if you live in a particularly hot climate. As a result, they tend to raise their labor prices for the season.
OEM vs. Non-OEM Parts
OEM stands for original equipment manufacturer and refers to parts designed by your AC manufacturer to fit your specific system. OEM parts tend to cost more than non-OEM parts, but they're often necessary to maintain your system's warranty. When gathering quotes from local HVAC techs, ask whether they use OEM parts in their repairs.
Diagnostic Fees
Most pros charge inspection fees to provide a quote before performing repairs. These range from $50 to $250 and may be waived by whichever pro you choose for the job. If you’re getting multiple quotes, you’ll pay a separate fee for each. Choose a pro who has experience replacing condenser fan motors and provides customer referrals and an up-front written estimate.
Service Bundles
Some HVAC companies offer discounts if you bundle your AC maintenance with other services, such as a local dryer vent cleaning service. You can take preventive measures against condenser fan motor replacement by having a tech perform routine maintenance on your HVAC system.
Additional Repairs or Services
Depending on the issues you're experiencing, you might need to repair or replace other parts of your AC system along with your condenser fan motor.
Blower Motor
On average, a new blower motor costs $560. This type of HVAC fan blows air over the heating and evaporator coils, serving both your AC and your furnace.
Compressor
An AC compressor costs between $800 and $2,300 to replace. It’s important to fix your condenser motor immediately at the first signs of any issues because it can otherwise damage your compressor. Since compressors are much more expensive to replace, it pays to get your condenser fan taken care of.
If your HVAC inspector finds extensive damage, or if you have an old unit and it’s time for an upgrade, compare the cost of installing a new AC unit to see if it makes more sense to conduct repairs, replace a part, or replace the entire system.
Warranties
As previously mentioned, if your AC is under warranty, you will only pay for labor. Most AC warranties last for five to 10 years and require that you regularly service your AC unit and use original equipment manufacturer parts to keep the warranty. Your home warranty might also cover HVAC maintenance.
Budgeting for AC Fan Motor Replacement
AC fan motor replacement requires professional tools and expertise, but there are steps homeowners can take to make the process more budget-friendly:
Check your warranty: If your AC unit is still under warranty, you may only need to pay for labor costs.
Schedule repairs in the off-season: AC repair costs are often lower during cooler months when demand is down.
Prepare your space: Make sure your HVAC technician has easy access to your AC unit to reduce labor time.
Practice regular maintenance: Regular servicing can prevent issues and catch problems early before they become costly repairs. An AC tune-up costs between $75 and $200.
Turn off a faulty unit: If you suspect your AC fan motor is broken, avoid using the system to prevent further damage.

Frequently Asked Questions
A condenser fan motor is a crucial part of your air conditioner that prevents the compressor from overheating. It pulls heat from your AC unit to cool the refrigerant moving through the condenser coils. This allows your system to blow cool air and keeps everything running smoothly.
The most common causes of AC fan motor failure include loss of lubricant in the system due to overheating and a rusted or leaking run capacitor. Poor lubrication can also cause failure in the belt drive, which may impact the AC fan motor. Weather and electrical components can also affect your AC. For example, a storm could send water into your motor windings and damage the internal components.
Air conditioner fan motors last about 12 years on average, though they can last longer if maintained well. This includes keeping them clean and cooled as needed with annual air conditioner checkups. Routine maintenance is essential to catch AC fan issues early. An HVAC inspection can cost between $70 and $500, while AC cleaning services may range from $100 to $400.
A broken AC fan motor may need replacement because this part usually can’t be repaired. Several things indicate it’s time to replace your AC fan motor, including buzzing noises, a constantly running fan, unusually high energy bills, or an aging system. If you notice these signs, call an HVAC pro for help before the faulty motor starts to strain other parts of the AC system.
There are clear warning signs of a bad AC fan motor, including unusual interruptions in the fan operation. The motor might be malfunctioning if you hear weird noises like grinding or rattling or if the fan continues to spin when the unit is off. These indicators compromise your AC’s cooling performance and increase your energy costs. Addressing these issues immediately by contacting a trusted HVAC professional prevents further damage and safeguards your HVAC's efficiency.
Replacing your AC fan motor takes a professional one to four hours. The technician will start by assessing your system and safely removing the damaged motor. If a new part needs to be ordered, it might take a few days. Once the part is available, your pro will install it properly and make sure your system is running smoothly.
