Locate the cause of weak or warm cooling
Weak cooling can result from restricted airflow, a fan fault, a coil condition, or a refrigerant problem; symptoms alone do not identify which one. The assessment should consider the indoor and outdoor equipment and, for ductless systems, the affected indoor head. Refrigerant measurements and leak checks require suitable equipment and trained handling. Findings help separate a serviceable component issue from a leak or compressor fault that may change the repair decision.
