Remove the old capacitor. Purchase the appropriate capacitor for your AC unit. They can be purchased at your local HVAC Supply Store or they can also be purchased online through Amazon, eBay, etc... The simplest way to make sure you buy the correct one is to order the same model number from the same manufacturer.
Without a functioning capacitor, your air conditioning unit may struggle to start or fail to produce cool air, especially during a heat wave. Capacitors typically come in two types: run capacitors and start capacitors, with some units using a dual capacitor to handle both functions.
The capacitor in your AC unit is a small but vital component that stores electrical energy and releases it to power the compressor, fan motor, and blower. Without a functioning capacitor, your air conditioning unit may struggle to start or fail to produce cool air, especially during a heat wave.
Before you start replacing the capacitor, it’s crucial to follow specific safety precautions to avoid injuries caused by the misuse of tools or improper handling of electrical components. First, turn off the power to the AC unit by switching off the breaker associated with your HVAC system. This step is critical to prevent electric shock.
To have these professionally replaced typically costs from $90 to $450. Following is how to replace both the capacitor and the contactor. Before opening the electrical cover on the A/C unit, be sure to shut off all power to the compressor unit and the indoor furnace or air handler, and verify that it is off.
Most new capacitors costs less than $60 and an AC contactor is less than $45. However, if you don’t have the necessary skills, or tools, leave these repairs to an HVAC repair professional. To have these professionally replaced typically costs from $90 to $450. Following is how to replace both the capacitor and the contactor.
