How a Dirty Filter Can Wreck Your HVAC System

A clogged air filter is one of the simplest problems—and one of the most damaging if ignored. In South Central Kentucky, dust, pollen, and humidity cause filters to load up fast.

What a dirty filter can cause:

  • Reduced airflow

  • Frozen AC coils

  • Overheated furnaces

  • Overheated heat pumps

  • Cracked heat exchangers

  • Higher energy bills

Most homes need a filter change every 1-2 months, sometimes more often depending on pets, allergies, or system design.

A clean filter protects your equipment, improves comfort, and costs very little compared to the repairs it helps prevent. If you’re unsure what filter your system needs—or how often to change it—a quick service visit can eliminate the guesswork.
