After a long day in the office or running errands, a house with a musty smell is the last thing you want. However, you might assume the smell will clear over time. But the situation might get worse if you do not act fast. That is because AC problems could lead to a musty smell, and an AC repair professional should fix the problem for the smell to go away. Here are three reasons you may have a stuffy home due to AC problems.

1. The Filters Need Cleaning or Replacement

Before air gets into your home from the air conditioning, it has to pass through the filters. Therefore, there will be dirt buildup on the filter after some time. You need to get a professional to help change the air filter since a dirty filter will affect the airflow and air quality. In addition, that will cause moisture to collect on the evaporation coil, promoting mold growth. Once your AC develops mold, you will always experience a musty smell when running.

2. The Drain Pans Need Emptying

The air conditioner removes excess moisture in the atmosphere and collects the droplets in the drain pan. So, if you do not clean the drain pan, it could cause mold formation. In addition, using the AC in such conditions will promote the spread of the musty smell to the rest of the house.

3. The Condensate Line Needs Unblocking

Another reason your house gets stuffy is using the AC when its condensate line is blocked. The condensate line is the PVC pipe responsible for draining the drip pipe. So, when the line blocks, water does not flow out. Unfortunately, the water accumulates in the pipes and provides a perfect environment for mold. As a result, your house becomes stuffy.

4. The AC Size Is Not Ideal for Your Home

The AC system comes in various sizes suitable for different homes. So, it is vital to get the right AC size for your house if you wish to get maximum efficiency. Otherwise, getting a smaller air conditioner than needed will increase the air cycle's speed, which might lead to a lack of de-humidification. As a result, your house will have excess moisture, promoting mold formation.

Musty smells could make you sick, especially if you have allergies or respiratory issues. That is why it is best to hire AC repair professionals once your machine starts producing a musty smell. A qualified AC expert will get to the root of the issue and ensure you enjoy the fresh air.
