How Much Does It Cost to Get an AC Capacitor Replaced?
Understanding the Cost of AC Capacitor Replacement
If your air conditioner suddenly stops working or won’t blow cold air, a faulty capacitor might be the cause. One of the most common questions homeowners ask is, “How much does it cost to get an AC capacitor replaced?” The answer can depend on a few key factors including the type of capacitor, labor rates in your area, and the condition of your HVAC system.
At Arctic Air, we help homeowners and businesses in Palmdale, Lancaster, Tehachapi, Rosamond, Quartz Hill, and Acton quickly diagnose and repair AC issues, including capacitor replacements. Let’s break down the cost and what you should know.
What Is an AC Capacitor and Why Does It Matter?
Your AC capacitor plays a vital role in starting and running your air conditioner’s motors. There are two common types: start capacitors and run capacitors. When a capacitor fails, you might notice your AC making a humming sound, blowing warm air, or not turning on at all. That’s when it’s time to take action.

Average Cost to Replace an AC Capacitor
On average, replacing an AC capacitor costs between $120 and $250, depending on the brand, size, and whether you’re using a single or dual-run capacitor. If your system uses a specialty part or if your unit is older, the cost may lean toward the higher end.
Here’s a quick breakdown:
- Basic capacitor replacement: $120–$150
- Premium or specialty capacitor: $180–$250

Should You Try to Replace the Capacitor Yourself?
Unless you have HVAC training, we don’t recommend DIY replacement. Capacitors hold an electrical charge and can be dangerous if mishandled. Trust a licensed HVAC technician to safely inspect and replace your capacitor while checking for other issues.

FAQs
Is it worth replacing the capacitor on an AC unit?
Yes, replacing a bad capacitor is often a simple and cost-effective fix that can restore your system’s performance. A faulty capacitor can cause your air conditioner to stop running, blow warm air, or short cycle. Replacing it can help you avoid more expensive AC repairs down the road.
What are the symptoms of a bad AC capacitor?
Common signs include the AC not turning on, blowing warm air, humming noises from the outdoor unit, frequent system shutdowns, or the fan not spinning. These are all indicators of a failing run or start capacitor in your air conditioner.
How long will an AC capacitor last?
Most AC capacitors last 8–12 years, depending on system usage, maintenance, and weather conditions. Heat, power surges, and frequent cycling can shorten their lifespan. If your air conditioner is older or not cooling well, the capacitor may be failing.
Can I replace an AC capacitor myself?
It’s not recommended. AC capacitors can hold a dangerous electrical charge even when the system is off. Unless you’re experienced with HVAC repairs and electrical safety, it’s safer to let a licensed HVAC technician handle the replacement.
How much is a bad capacitor for an AC unit?
The cost of a replacement capacitor generally ranges from $120 to $250, including parts and labor. The final cost depends on the type and size of the capacitor, as well as your system’s make and model.
