Surge Protection

A HVAC surge protection system works similarly to a surge protection system for computers. If an electrical surge occurs, your HVAC surge protector will shut down the system so that your HVAC unit does not get damaged.

Once the HVAC surge protection system kicks in, you will need to know how to restart your HVAC unit. Usually, this is easy, but you should ask the installer or consult the manual you got with the HVAC system to figure out how to reset your HVAC system in case of an emergency. You can often contact the manufacturer to find out about the internal HVAC surge protection system.

Another form of HVAC surge protection will be for a malfunctioning HVAC unit. If something goes wrong, the system will shut down. This can be quite annoying, but it is a safety measure for your HVAC system. You will probably need to contact a technician to find out why the HVAC surge protection unit is being triggered if you are not sure why this is happening and it is happening often.

Many people find a HVAC surge protection system to be a nuisance, but in reality, a HVAC surge protection system will protect you, your family, and your HVAC system. If the HVAC surge protection is not working properly, you will discover that you are in need of a whole new HVAC system.
