As a business owner, you likely have concerns when there is an odd odor in your building. Not only does it create an unenjoyable environment for employees, but it can make customers not want to spend time in your store. That's why it helps to know how to get to the bottom of a problem when the odor is caused by your business's air conditioner. If you have a musty odor in your building, it could be due to these 3 problems. 

Filtration Problems

All air conditioners have a filtration system that is designed to prevent contaminants from getting into the cool air that is produced. It is essential to have these filters in place, since they prevent dirt and debris from getting onto the evaporator coil, which can cause it to freeze up.

Unfortunately, air filters become clogged quite easily, which is why frequent replacement of the filter is recommended. In some situations, the air filter may have mold on it that is passing that odor into the air as it goes through the filter. You'll need to replace the air filter frequently if you want to keep the air smelling clean to everyone in your building. Between employees and customers, you have more dirt and allergens brought into the air than you would have in your home, so make sure to stay on top of this problem.

Humidity Problems

Another reason for a musty odor is due to humidity problems. There may be too much humidity in the air that is being produced, which can lead to an odor in the air that is traveling through the ductwork. Have the humidifier component of the HVAC system inspected to make sure that you do not have too much water going into the air.

Oversized AC Problems

It is important to make sure that the air conditioner for the building is the proper size, since having an air conditioner that is too big can be problematic. If the air conditioner is pushing too much cold air into the ductwork, you will have condensation form in the ductwork and cause mold to grow. This mold will then create an odor that you'll smell in the air every time that the air conditioner is turned on. Not only will you need to have the air ducts cleaned, but you'll need to have a professional come in and fix the problem caused by the oversized air conditioner.
