Protecting HVAC Systems With The MARS Surge Protective Device

Find out why installing a MARS surge protective device is essential to protecting your customer’s HVAC system from threats they may not even be aware of.

Everyday household appliances such as a dehumidifier, microwave or garbage disposal cause voltage spikes that are absorbed by other appliances like the HVAC system. Over time, these spikes damage the HVAC system, which is the most expensive appliance in a home and thus needs to be protected. Installing one of the surge protection devices from MARS provides local protection for the vital parts of the system including, but not limited to, compressors, ECM motors and control boards.

MARS offers 3 types of surge protection devices:

  1. Indoor Surge Protective Device (MAR83904): Designed specifically for 120V furnace and air handler applications.
  2. Outdoor Surge Protective Device (MAR83905): Designed to protect HVAC equipment from power spikes, surges and transients.
  3. Disconnect Box with Integrated Surge Protective Device (MAR83915): Provides a quick and clean installation with additional security from the weather-resistant metal enclosure.
