Help! My Home’s AC Smells Musty When I Use It!
While an air conditioning system that smells musty may be alarming, it’s important to understand the causes behind the smell before taking any action. Read on to learn about some possible reasons why your Longmont, CO home’s AC smells musty when you use it.
1. Dirty Air Filter
Air filters work by trapping dirt, dust, and other airborne particles before they can enter your home. However, air filters can become clogged with debris, reducing their efficacy. This can result in your AC smelling musty because the trapped particles can begin to rot, releasing a foul odor into your home.
It’s important to change or clean your air filter at least once every 90 days. This may vary depending on the manufacturer’s instructions, though. It’s even better to change it once each month.
2. Biological Growth
Biological growth is usually caused by excessive moisture in the air, which can happen if there’s a leak in the unit or if it isn’t draining properly. Inspect your AC unit for any signs of leaks and make sure that the drain line is clear of any obstructions. If you suspect that biological growth might be present, the best idea is to call a professional.
3. Improper AC Unit Size
If your AC unit is too small, it will have to work overtime to cool your home. This can cause the unit to overheat, create excess condensation, and produce a musty smell. Conversely, when an AC unit is too big, it may not run long enough to properly dehumidify the air.
As a result, the unit will cycle on and off more frequently, leaving excess moisture in the air. Our professional technicians can help you select a unit that’s properly sized for your space. They’ll also make sure that they install your unit correctly and that all ductwork is properly sealed.
