They were great! They were nice, informative, efficient and courteous to our needs. They also informed us of an issue from the original install of our old system and are going to come back out to correct it for us."

Central a/c service or repairs FAQs

An AC capacitor provides the electrical energy needed to start and run your air conditioner's motors. It stores and releases electricity to keep the compressor and fans running smoothly. Without a functioning capacitor, your AC unit may not start or operate efficiently. If you notice problems with your AC unit, contact a professional to diagnose the problem and see if you need to replace your AC capacitor.

AC capacitors last between five and 15 years, with an average lifespan of ten years. Environmental conditions and system usage can affect their lifespan. Regular maintenance can help extend the life of your capacitor. When your replacement capacitor is installed, be sure to ask your AC technician about best practices for maintenance and ongoing service to keep your unit in good condition for as long as possible.

While you might save between $60 and $200 by replacing the capacitor yourself, it's not recommended unless you have electrical expertise and proper safety equipment. Replacing a capacitor involves risks like electric shock and potential damage to your AC unit. It's safer to hire a certified HVAC technician who ensures safe and accurate installation.

It's safest to have a qualified technician inspect your AC capacitor. If you decide to look at it yourself after turning off all power, you can carefully remove the front panel and check the capacitor for any visible issues. However, handling electrical components carries risks, so professional inspection is recommended.
