Service call at a laser hair removal clinic in Blue Bell, PA β manager reported wet floors, hot air coming from the return grille, and an unusual odor inside the space.
Went up on the roof and found the filter access door had come loose β the screws had pulled out of the mounting strip, and the door had slid down onto the economizer hood. Wide open.
After a rainy weekend, the unit had been pulling in outdoor air, humidity, and everything that comes with it β including odors from the neighboring restaurant. All of it going straight into the space below.
π§ Reinstalled the filter door and secured it properly β new screws going directly into the unit instead of the strip, so it won't happen again.
β
Took temp readings and verified operation. Unit running and cooling properly. No more odors, no more wet floors.
Two calls in a row where the unit itself was fine β just something on the outside that shouldn't have been open, was.
