When you hire an HVAC pro, the average AC contactor replacement cost is $220, but you could spend anywhere between $20 and $320. Below, we’ll explain the factors that affect the cost to replace an AC contactor, including the price of parts, labor, and additional repairs. Your home will be cool again in a jiffy.
Based on the price of parts alone, AC contactors are one of the most affordable HVAC components to replace. You can purchase a new contactor from a hardware store or online retailer for $15 to $70. There are a few different varieties (for example, single-pole versus double-pole), so if you buy your own, it’s important to choose one that matches your current contactor.
Labor will account for a majority of the cost to replace a contactor on an AC unit. For an HVAC professional, installing a new contactor is a routine service that should only take a few minutes. You can expect to spend between $100 and $250 on labor, depending on your location and the time of year.
Your labor costs will be on the pricier end of that range if you live in an area with a high cost of living (like New York or San Francisco). Similarly, you’ll pay more for labor if you hire an HVAC pro during the summer, which is the busiest—and most expensive—season for HVAC repairs.
Parts and labor are the primary expenses when replacing an AC contactor, but there are a few other variables that can impact the overall price of the project.
If your AC is still under the manufacturer’s warranty, it might cover the cost of replacing the contactor. In that case, you’d likely just need to pay for labor, as you can see below.
| Warranty Status | Average Replacement Cost |
|---|---|
| Under warranty | $100–$250 |
| Out of warranty | $115–$320 |
An HVAC professional shouldn’t have much trouble accessing your AC contactor. But if your unit is in a hard-to-reach spot or covered by bushes, the pro may need to put in more effort to get to it. This could potentially increase your labor costs.
Sometimes, a contactor will wear out simply due to age or a lack of proper AC maintenance. If either of these things is to blame for your contactor failure, you could soon experience other HVAC issues as well. Common AC repairs include:
Capacitor replacement costs: $100–$250
Compressor replacement costs: $800–$2,300
Condenser replacement costs: $1,050–$5,000
Fan motor replacement costs: $100–$700
Drip pan replacement costs: $200–$1,000
AC replacement costs: $3,900–$8,000
It’s tempting to DIY the replacement of your AC contactor, especially when it’s a fairly simple fix and labor costs far exceed the cost of the part. But whenever a project of any size involves electrical work, it’s better left to the pros to avoid personal injury. Hiring an AC installer near you to replace your AC contactor will ensure the job gets done safely and quickly.
Even if you can do a task on your own, sometimes it’s worth paying a professional to handle it. Replacing your AC contactor is one of those times:
A pro installer can replace the contactor in minutes—a good thing if it’s in the middle of winter or summer and you are relying on a fully operational HVAC system.
They can troubleshoot any other issues affecting your HVAC’s performance.
If you DIY the replacement and make an error that causes additional problems for your HVAC system, you risk voiding its warranty.
By working on your HVAC system or undergoing important repairs on your own, you could void your unit’s warranty or further damage the system. Leave HVAC repairs to the pros.
Since AC contactors are inexpensive and easy to install, trying to repair a faulty one isn’t worth your time or money. If yours fails, you’re better off replacing it with a new one.
There’s one slight exception: Sometimes, dirt and debris can collect on the contactor and cause it to malfunction. If that’s the case, it might just need a good clean to start working again. Your HVAC pro can do this for you during a service appointment.
Even though replacing an AC contactor is one of the more affordable HVAC projects, you may still be looking for ways to minimize costs. These tips can help:
Buy the replacement part yourself: AC contactors are readily available online and through hardware stores. You could save a bit of money by purchasing your own and having it ready for the technician to install. Just make sure the new one matches the current model’s voltage, number of poles, and other specifications.
Bundle multiple services: If your HVAC system has other issues (aside from the contactor), ask the pro to check them out during their visit. Tackling multiple projects at once could reduce future labor costs.
Shop around: Get quotes from at least three local contractors. Review the details of each quote (including price and project timeline), as well as each company's customer testimonials and reviews.
If you plan on selling soon, installing a new contactor is an affordable project that can deliver an excellent return on investment (ROI). Here’s why.
Without a functioning contactor, your AC won’t run properly. By replacing your faulty contactor, you can get your HVAC system back in good condition—which can earn you major points in the eyes of prospective buyers and help your home sell for more money.
Something else to consider: If your HVAC system needs other upgrades, you might consider replacing the entire system. Installing a new HVAC has an ROI of about 30% and can bump up your home’s value by 5% to 7%.
Confirm whether you or the pro is responsible for getting the replacement contactor.
Discuss what, if any, prep work needs to be done to allow full access to your HVAC system.
Ask whether any additional services, such as an HVAC cleaning or tune-up, are available.
