# How to Hook Up an HVAC Capacitor
Your HVAC system, or heating, ventilation and air conditioning system, controls the temperature in your home and runs on electricity. The HVAC system uses a capacitor to store electricity that it then redirects throughout the system. If your capacitor stops working, your condenser may start making noises or the motor and compressor in the condenser may fail. Avoid expensive repairs to your HVAC system by installing a new capacitor yourself rather than depending on an air conditioner repairman to install the part for you.
