Ever wonder why your AC compressor burns out or your electrical components start pulling dangerously high amps? It usually isn't a part failure—it’s an airflow problem. 💨
A lot of people think opening up the blower compartment door on a package unit makes it "breathe easier." It actually does the exact opposite. Without that door, the fan pulls an unrestricted flood of heavy air, overloading the motors. Even worse? The air completely bypasses the proper coil, suffocating the system and forcing the compressor to choke and work twice as hard.
Watch what happens to the amp draws the second that door comes off—and how they drop right back into place the moment the system is sealed back up.
⚠️ The exact same thing happens if you run your system without an air filter. Dirt cakes the coil, cuts the airflow, and simulates this exact same electrical nightmare.
Keep the doors on, keep the filters clean, and let the system breathe the way it was engineered to!
