AC compressor not starting — Alicante, Valencian Community
When the outdoor AC unit hums, clicks, or stays completely silent while the indoor fan blows warm air, the compressor likely isn't starting. Common causes include a failed capacitor, a burned-out compressor motor, a tripped high-pressure switch, or low refrigerant levels. The compressor is the most expensive component in the system — running a failing one can cause total unit failure. An HVAC technician can diagnose whether the fix is a $150 capacitor swap or a compressor replacement that may justify upgrading the entire system.
Waarom dit veel voorkomt in Alicante
Alicante's extreme summer heat (regularly 38–42°C) makes air conditioning essential rather than optional, and HVAC systems work at maximum capacity for 3–4 months of the year. High UV exposure accelerates deterioration of outdoor condenser units and their mounts. Many older properties rely on individual split units rather than centralized systems, increasing maintenance complexity.
