1. A leakage protection system for a heating, ventilation, and air condition (HVAC) system, the leakage protection system comprising:
a power source;
a louvered assembly including a frame, slats spaced apart vertically within the frame and extending from a first side to a second side of the frame, an actuator rod operably coupled to the slats, and a spring;
a solenoid operably coupled to the actuator rod;
a first pressure switch disposed electrically between the power source and the solenoid, wherein the first pressure switch is configured to open in response to an operating pressure in a fluid conduit of the HVAC system falling below a first pressure threshold; and
a second pressure switch disposed electrically between the first pressure switch and the power source, wherein the second pressure switch is configured to open in response to the operating pressure in the fluid conduit of the HVAC system exceeding a second pressure threshold.
