HVAC Capacitor Cost
The average HVAC capacitor cost is around $170. Prices generally range between $120 and $250, including professional installation. Branded units are more expensive, costing upwards of $400 or more. The price you pay depends on the brand, model, voltage and the labor required for installation.
The capacitor’s purpose is power storage. As the AC runs, it collects and stockpiles energy that kickstarts the unit when it begins a new cycle. This function is essential because, as it starts up, the AC requires more power than your home’s electricity can provide. Without the help of the capacitor, your home’s HVAC system cannot run properly.

AC Capacitor Cost
The cost of an AC capacitor is typically between $9 and $25. Professional installation usually costs between $60 and $200. Replacing this part is a common AC repair cost and is often relatively inexpensive. However, depending on the type of capacitor you need, prices will fluctuate.
AC Dual Capacitor Cost
Most dual run capacitors cost between $15 and $45 as a standalone part, but prices vary depending on the brand and voltage. Dual capacitors can power two electric motors, making them ideal for larger HVAC systems.
Air Conditioner Start Capacitor Cost
Most AC start capacitors cost between $9 and $25 for the part alone. Higher-end models typically cost between $52 and $75, with some costing as much as $175. These capacitors provide the jolt of power needed for the system to start a new cycle.
Central Air Run Capacitor Cost
The cost for a run capacitor generally ranges between $8 and $30. This capacitor helps provide power to keep the AC running for longer periods of time.
Blower Capacitor Replacement Cost
The price for a new blower capacitor is typically between $9 and $12. This provides the necessary power to spin the blower motor so the fan moves in the furnace.
Heat Pump Capacitor Cost
The cost for a replacement heat pump capacitor generally ranges between $15 and $25. This stores energy and releases it when it’s time to run the compressor or motor. The main difference between a heat pump vs. an air conditioner is that a heat pump works as both an AC and a heater.
Capacitor Prices
A new AC capacitor usually costs between $9 and $45, though brand-name and higher-end models could be between $52 and $175. Final costs vary based on the unit’s model and voltage level.
Capacitor Replacement Costs
The labor required to replace a capacitor is generally between $60 and $200. The price depends on the level of experience and the time it takes to complete the job. Most HVAC professionals will be able to replace a capacitor in under an hour.
DIY Capacitor Replacement vs. Hire a Pro
A common concern homeowners have about professional capacitor replacement is the relatively high cost of labor compared to the low cost of the part itself. This can tempt any frugal DIYer into trying to take on the task themselves. But due to the risks involved, as well as the extra time and hassle, it’s strongly recommended you find an HVAC contractor in your area. There are a few reasons why this is the best and safest option.
A Pro Saves Time
Most HVAC companies are able to send someone to your home that day, and the job usually takes under an hour. If you choose to DIY the project, it will likely take you much longer to source the parts, learn the process and carry out the needed steps.

A Pro Eliminates Risks
Working with AC parts, or any electrical components, can be extremely dangerous. A capacitor can shock you, leak toxic liquids or even burst and cause serious injury. Finding a local HVAC contractor ensures the job is done safely and correctly.
A Pro Protects Your HVAC System
While trying to fix your HVAC system, you can damage it further. If you’re not experienced, you can end up paying extra costs for AC compressor replacement—or even the cost for a new AC unit.
A Pro Provides Accurate Diagnostics
When your home’s AC isn’t working, it isn’t always immediately apparent what’s causing the issue. A local HVAC repair service can quickly diagnose your problem and often has the necessary parts on hand.
FAQs
How long do AC capacitors last?
An AC capacitor will generally last around 20 years under the right conditions. However, there are a few factors that can significantly reduce its lifespan:
- Choosing too low of a voltage for the existing unit
- Prolonged exposure to high heat and hot climates
- Neglecting AC maintenance
- Not servicing your AC regularly
- Faster than normal cycles
- Poor product design or faulty parts
To get the most out of your capacitor, keep the outdoor AC system in a clean and shaded area. It’s also important to seek qualified air conditioner services near you rather than trying to fix anything yourself.
What happens when an AC capacitor goes bad?
When your capacitor isn’t working, the necessary power can’t reach vital elements of your HVAC system, such as the fan, compressor and blower. This can quickly cause your AC to stop cooling your home. Luckily, replacing your AC capacitor is usually a quick and simple fix.
