An Aiea homeowner called after their AC stopped cooling entirely, with only warm air coming from the vents. Because a complete loss of cooling can stem from several different causes — electrical, mechanical, or refrigerant-related — the visit began with a structured diagnostic check.
Using a multimeter to test the outdoor unit's electrical components, we identified a specific part that had failed and was preventing the compressor from running correctly.
With the cause confirmed and explained to the homeowner, the faulty component was replaced and the system was tested through a full cycle to confirm cooling had been restored before we considered the visit complete.
