AC tips in Abbeville, LA

An air conditioning unit is an outstanding appliance that helps keep your house cool and comfortable. Nonetheless, when it begins emitting a musty smell, it can be an unpleasant experience. The musty odor might indicate microbial growth or other problems within your AC system. Here are three reasons your cooling unit may emit a musty smell and practical tips to solve the problem.

1. Mildew or Mold Growth

One of the common reasons for a musty AC is that there’s mildew or mold in your vents or ductwork. If you notice a strange smell each time you turn on your air conditioner, it indicates something is wrong. By getting your vents and air ducts checked and cleaned and using UV filters, you can prevent this problem in the future.

2. Dirty Evaporator Coils

Your AC unit’s evaporator coil absorbs moisture and heat from the indoor air. Over time, dust, dirt, and debris can accumulate on the evaporator coil, preventing it from working correctly. Furthermore, the coil might become an ideal breeding ground for mildew and mold, leading to the musty smell you might be experiencing. Having your AC unit cleaned and maintained regularly can help avoid this issue. A UV lamp might also help prevent mold from developing.

3. Clogged Drain Line

Another reason for a musty odor from your cooling unit is a clogged drain line. The AC drain line is responsible for removing condensation from your AC system. When the drain line gets clogged, water will accumulate within the unit, leading to microbial growth and a musty odor. Regularly cleaning your drain line is essential to ensure condensation can easily escape from the air conditioner without building up.
