What You Need to Know About Your Air Conditioner Filter

Dependable Service Since 1926

Do you know where the air filter in your air conditioner is? Did you know that your air conditioner had an air filter? You do, and it’s actually a pretty important thing to maintain if you want your system to operate properly. If the air filter isn’t properly maintained, it will cause all sorts of issues for your system. Read on to find out more about your air conditioner air filter.

The Importance of Air Filters

The AC air filter is a part designed to protect your air conditioner from dust and debris that might blow into it. It sits in the air return section of the ducts, and all air that flows into the air conditioner will move through the filter first. The air filter needs to be cleaned out at least once every three months, in order to keep operating properly. If that does not happen, the air filter will eventually become clogged. That could destroy your entire air conditioner if you aren’t careful.

Frozen Coil

If the air filter becomes clogged, most of the air flow into the air conditioner will become blocked. This will cause issues for your evaporator coil. The evaporator coil evaporates refrigerant to absorb thermal energy from the air in your ducts. This causes the temperature around the coil to drop constantly. Normally, the flow of hot air from the ducts prevents the coil temperature from dropping too low. Without proper air flow, though, the evaporator coil will freeze over.

While the coil is frozen over, the output of your air conditioner will drop significantly. The ice can also spread to other parts of the system and cause them to break down. If you want to prevent this from happening, make sure that your air filter is cleaned out at least once every three months.
