Cost Insights
The AC capacitor itself doesn’t usually exceed $45.
You’ll often pay between $200 and $400 in labor fees for this project.
The cost of AC capacitor replacement depends on unit type, HVAC system size, labor rates, and more.
Replacement is not DIY-friendly because of the risk of injury and damage to your AC unit.
The AC capacitor stores electric energy to power the compressor and fan motors when you start your air conditioner, and it often lasts 10 to 20 years. Replacing an AC capacitor costs an average of $250, which includes the price of the capacitor and labor for installation. However, the total cost could be as low as $200 or as high as $400, depending on the type of AC capacitor and the complexity of the replacement. AC capacitor replacement costs primarily consist of labor, as the capacitor itself rarely exceeds $45.
AC Capacitor Cost by Unit Type
Run, start, and blower AC capacitors tend to be the least expensive, while dual-run and heat capacitors could cost an extra $20 or more. If you’re unsure what type of capacitor you have, a local HVAC technician can help.
Here’s a breakdown of AC capacitor costs by type:
| AC Capacitor Type | Average Cost Range | Description |
|---|---|---|
| Run capacitor | $8–$30 | Helps the motor run smoothly and efficiently |
| Dual-run capacitor | $15–$45 | Handles the compressor and the outdoor fan motor |
| Start capacitor | $9–$25 | Provides a large initial burst of energy when the motor turns on |
| Blower capacitor | $9–$12 | Helps the indoor blower motor run efficiently |
| Heat pump capacitor | $15–$25 | Found in a heat pump system |
HVAC Pro Costs
A local HVAC expert will charge between $200 and $400 in labor alone to replace your AC capacitor. Keep in mind that many professionals charge a flat rate for an AC capacitor replacement, which includes the cost of the capacitor itself. This all-inclusive flat rate often ranges from $300 to $600. If the fix is an emergency or requires the contractor to come to your house on a weekend or holiday, you’ll pay an additional fee.
Each HVAC pro sets the rate for replacing an AC capacitor. Some contractors include a diagnostic fee to assess the problem, while others charge only for labor to replace the part. When contacting pros for quotes, ask them if they charge a diagnostic fee and what that service includes.
From one homeowner to another
Manny was very trustworthy and professional. He gave me a very fair price. Within 24 hours he had done his inspection and given me an estimate. It's the first time I talked to an HVAC company that didn't make me feel like I was getting overcharged. One of the other companies I spoke to was trying to charge 6 times the cost. He took lots of pictures and video and explained step by step what was done wrong by the other contractors and what he would need to do to fix it. He was able to do the work the day after I accepted the estimate. He completed all the work in one day. I am confident and very relieved to say that my HVAC system is set up properly.

Additional AC Capacitor Cost Factors
You’ll pay for the AC capacitor and the labor to install it, but the exact costs will vary based on a few important factors. Here's what to expect.
HVAC System Size
As the HVAC system size increases, the electrical components—like the compressor and fan motor—require more power to operate. To provide the necessary startup and running support, the AC capacitor needs a higher capacitance rating, measured in microfarads. Higher-capacitance capacitors typically cost more.
HVAC Accessibility
HVAC technicians may charge extra if the air conditioner unit is in a particularly hard-to-reach spot. This isn’t often a concern for residential homes, but you may encounter extra fees if the pros need to clear away bushes or move aside clutter. Ensure your AC units are clear before a technician visits to avoid extra charges.
Seasonality and Weather Conditions
When the weather warms up during the summer months, many homeowners turn on their AC and discover they have problems. This leads to a higher demand for HVAC technicians, who increase their maintenance and repair rates in response. Demand may also spike during heatwaves. Call an AC repair company in the spring before demand increases to catch problems early and save on labor.
Product Manufacturer or Brand
Some air conditioner brands cost more than others due to quality, materials, and other factors. For example, Trane and Lennox units tend to be the most expensive, while Goodman and York are more budget-friendly picks. Capacitors for higher-cost brands will be more expensive as a result.
Air Conditioner Age
If you have an older AC unit, especially an outdated model, it may be more challenging to source a replacement part, which can lead to higher prices. It’s also common for a pro to find other issues while replacing the capacitor in an older AC unit.
Home Location
Location tends to affect labor costs, as well as unit costs to a lesser extent, due to factors like shipping and availability. Obtain several quotes from contractors in your region to compare fees.
Warranty
Capacitors are relatively affordable and usually don't have their own warranty. However, the manufacturer's warranty for your entire AC unit might cover capacitor replacement. Alternatively, if you have a home warranty that covers your AC unit, it may be less costly to submit a claim than to pay for the replacement yourself.
Additional Repairs
If your AC capacitor has problems, it won't be long before other parts in your AC unit begin to fail as well. HVAC repairs cost much more when multiple parts must be repaired or replaced. Some common AC repairs include:
Damaged compressor: $750–$2,000
Thermostat replacement: $150–$350
Fan coil replacement: $600–$2,000
Burnt-out motor: $200–$700
Have your HVAC system inspected regularly and replace a damaged capacitor right away to avoid the higher costs of additional repairs.
DIY vs. Hiring a Pro to Replace an AC Capacitor

If you pride yourself on being handy, you can test an AC capacitor and replace it yourself for around $60 to $100, including the cost of the unit and the tools needed for installation. This can save you $200 to $400 in labor costs, but taking matters into your own hands requires preparation and extreme caution.
DIYing without proper HVAC and electrical knowledge risks leaving your home without heating or cooling. Plus, you could get seriously injured or electrocuted. The AC capacitor could also leak toxic liquids or burst, potentially causing more serious injury. Contact a local air conditioning repair specialist to save time and eliminate possible risks.
Angi Tip
It’s important to note that this isn’t one of those DIY tasks that you can figure out as you go. You should not attempt it unless you’ve done your homework, are fully equipped with the proper safety gear, and understand electrical best practices and the inner workings of an AC unit.
Tips to Save on AC Capacitor Costs
HVAC capacitor replacement costs are relatively inexpensive. Still, there are some ways to minimize costs:
Buy the capacitor yourself: If you’re handy, you can purchase the replacement capacitor yourself. Just make sure it matches your AC unit’s specifications and have it ready for the technician.
Keep up with regular maintenance: Scheduling regular check-ups for your AC can catch capacitor issues early, potentially avoiding emergency service charges.
Plan for off-season repairs: If possible, schedule the replacement during the spring or fall when HVAC services are typically less busy.
Join a maintenance plan: Many companies offer HVAC maintenance plans that include regular check-ups and discounted repairs. Joining one of these plans can save you money over time and keep your system running smoothly.
Get multiple quotes: Get quotes from at least three contractors to find the best rate in your area.
