Can a dirty filter affect AC?

The Air Conditioning Unit is Too Hot If the filter is very dirty, you may even feel warm air coming out of the back of the unit. A clogged filter forces the air conditioner to work harder to keep the house cool. This will lead to more frequent AC repairs and, ultimately, shorten the lifespan of the unit.

Does cleaning your AC filter make it colder?

Freezing Up: A good, clean air filter allows air to flow freely out of your unit. A dirty air filter restricts the flow of cold air, causing it to build up inside the air conditioner and lower the internal temperature. Given enough time, that buildup of cold air can eventually cause ice to form on the coils.

Is it better to have a dirty air filter or no air filter?

What does it mean when your AC filter is wet?

A wet air filter commonly indicates a clogged condensate pan or condensate drain lines.

Another possible cause is moisture that may be falling directly onto the filter from the evaporator coils.
