how to get rid of musty smell from air contitioner???

Answer 1

Is this a central or window unit? In either case the pan drain line may be clogged and or evap. coil is dirty. To confirm this Step1. If this is a window unit pour water slowly into the coil infront of u inside the house. Eventually water should start dripping outside from the unit. Usually from a drain port. Most units are so installed that water runs out, not into the house. This water is from condensation. You can also take windex and spray onto the coil, then spray water to rinse it. Step 2. If it's a package central unit, one must go up the roof. Disconnect the unit eg. shut the power down, turn off the circuit breaker. Remove the top of the unit, clean evap. coil and drain line. Step 3. A split sytem one can get to the evap coil in the attic,basement or closet, depending on the installation. Then clean it and the drain line. Sometimes the smell can also be due to fan running without the compressor energized, warm air. In this case see if you can cycle the fan off with the compressor.Good Luck.

Answer 2

first clean your filters....then from the outside use a mixture of 1/4 cup vinegar....1/4 amonnia to 1 gallon water. turn on air and spray mist into the suction flow. spray lightly so there is no strong order blasting through the air. then repeat from the inside... the smell is really the smell from inside the house.
You should do this when no one is home but yourself. so you can spray as much as needed. this is also something you could do before putting it away for the winter...that way nothing has time to set and and mold up you air condictioner

Answer 3

Clean the filters. This is the first thing I would check. If that does not do it, then I would suggest taking the filters out to see if anything found its way into there and died. Last, as a final resort before tearing the AC apart, call somebody.

Answer 4
