HVAC Capacitors Defined

A fan coil unit is an application that uses a coil and a fan to heat or cool a room without connecting to ductwork. To start this unit and keep it running optimally, capacitors are required.

An HVAC capacitor is a shiny, cylinder-shaped battery that resembles a can. They are responsible for powering the system’s motors and stabilizing the voltage that runs through your HVAC system. Your outdoor fan, motor compressor, and blower should have their own set of capacitors to start the motor and keep it going.

There are two main types of HVAC capacitors – “start” and “run”. Start capacitors are used to – you guessed it – start the unit while “run” capacitors perform the role of producing and stabilizing energy to keep it running.

Are They Like Batteries?

Yes and no. Capacitors function similarly to and resemble batteries, however, they are different. Batteries store energy chemically, while capacitors store physical energy that resembles static electricity. The process of replacing this device is also a bit more technical than simply replacing a battery, as these high-voltage devices are connected to wiring within the system.

Commercial HVAC Parts carries a variety of quality  “start” and “run” capacitors necessary for your cooling tower application. To shop, visit here!
