When a clogged air filter allows dirt to build up on the coils, the coils can become so cold that they ice up. When the system cycles off, the ice melts and drips water, potentially causing costly damage to the equipment. Occasionally, a clogged HVAC filter can be sucked from its position into the system equipment, which can pose a fire hazard.
