A capacitor is a device made to hold an electric charge, with pairs of conductors that are separated into parts by an insulator. Your HVAC system needs the capacitor to run the motor. Capacitors come in various sizes to suit your motor size. Whatever your HVAC unit and motor, you need a functioning capacitor for your system to work.

There are two primary types of capacitors–single and dual run. Start capacitors boost the compressor’s energy when the HVAC motor starts. Run capacitors work constantly while the motor runs. They are commonly composed of polypropylene film; this lets the stay energized when the HVAC system runs for long periods.
Single run capacitors are usually found in small AC units. They have two connections and can be attached to a single motor. There are not a lot of differences between single and dual run capacitors. Dual capacitors are much more powerful and can run in larger AC and heat pump models. They have three connections, and so when you need to replace a capacitor, you need to know how many connections your first had to know which you need. That is where your HVAC expert comes in.
