Signs Of A Dirty Or Clogged Filter
Reduced airflowis a clear sign of a dirty air conditioner filter. The air feels weaker coming from vents. It takes longer to cool the room. This happens because dust blocks the filter’s holes.
Unusual odorsmay come from the AC. A clogged filter traps dirt and mold. These cause a bad, musty smell in the air. The smell often gets stronger when the AC runs.
Increased energy billscan happen too. A dirty filter forces the AC to work harder. This uses more electricity. Bills rise without any other changes in usage.
