Weak cooling can start with a dirty filter or poor airflow, but it may also involve the refrigeration circuit or controls.
Read guide →A blocked drain or dirty indoor unit is common, while poor unit level or a frozen coil can create similar symptoms.
Read guide →Freezing usually points to an airflow or operating-condition problem, and the unit should not be kept running while frozen.
Read guide →Odors are often linked to moisture, dust and drainage, and the source should be cleaned rather than masked with fragrance.
Read guide →The type of sound matters—buzzing, rubbing, knocking or vibration can point the inspection in different directions.
Read guide →Frequent cycling can increase energy use and may involve controls, airflow, electrical protection or system sizing.
Read guide →Start with power, remote settings and the breaker, and stop if the breaker trips repeatedly.
