Homeowner questions
FAQ
Can I fix an AC not cooling by changing the filter?
Sometimes a severely clogged filter contributes to poor airflow, but it will not fix electrical or refrigerant-side problems.
Why is the outdoor unit not running?
It could be a breaker, disconnect, capacitor, motor, contactor, control, or safety-switch issue that needs diagnosis.
