Why AC smells musty

When you turn on your air conditioner, you may at times expect cold, fresh air, but all you get is an unpleasant odour. There can be any problem in your AC if it smells for a long time when it is switched on, and it is more than just an annoyance. If AC is smelling for a long time, it is an indication that you should contact a professional to get issue and fix this problem. You need to know the cause because it can help you fix the issue quickly and maintain a healthier indoor space. 

1.Musty Air Filters

Dirty air filters are the most common reason behind a musty smell from the AC because air filters capture dust and dirt to maintain your home’s air pure, but when they’re blocked, they also ensnare dampness. That’s a recipe for mould to develop directly on the filter. The offensive smell of mould is sent through your vents while your air conditioner is running. Regularly filter replacement or maintenance makes the air cleaner and minimises the accumulation of such particles. Now is an excellent time to update your filter if you can't recall when you last did so.

2.Extra Moisture in the System

Leaks, insufficient water drainage, or even simply a humid environment may all be contributing to an excessive amount of moisture. The insufficient amount of water accumulates in the ducts, coils, or insulation when the air conditioning system is unable to evaporate it. That type of damp environment is excellent for mould growth. 

3.Development of Mould and Mildew

Development of mould or mildew is one of the most common root causes for an unpleasant AC odour. During operation, your air conditioner naturally gathers moisture. The ideal conditions for the formation of mould are created when this moisture becomes trapped inside filters, ducts, or coils. This eventually causes the unit to smell musty or wet when it is switched on.

4.Blocked with dust, Drain Line

A blocked drain can also be a reason because AC takes humidity from the air and drains that moisture down a condensate drain line (if this line becomes blocked, water can gather within the unit), a clogged drain line may be the origin of the AC odour. Musty smells are frequently caused by stagnant water.
