What is a contactor, and what does it do in my hvac system

A contactor is an electrical relay that is used in HVAC systems to control the flow of electricity to various components such as the compressor, fan, and blower motor.


The main purpose of a contactor in an HVAC system is to switch the electrical power to the various components of the system on and off as needed. When the thermostat signals the HVAC system to turn on, the contactor receives the electrical signal and allows power to flow to the system’s components. When the thermostat signals the system to turn off, the contactor breaks the electrical connection and stops the flow of power.


Contactors are essential components in HVAC systems because they allow for precise control over the flow of electrical power to the system’s components. They can also help to prevent damage to the system by preventing power surges or other electrical issues that could cause damage to the components.


If you are experiencing issues with your HVAC system, such as the system not turning on or running continuously, it is possible that there may be a problem with the contactor. A licensed HVAC technician can diagnose and repair any contactor-related issues to ensure that your system is functioning properly.
