Heat pump not defrosting — Torrevieja, Valencian Community
Heat pumps naturally build frost on the outdoor coil in cold weather, and they run automatic defrost cycles every 30–90 minutes to melt it off. When defrost fails, ice encases the entire outdoor unit, blocking airflow and destroying efficiency — you'll notice lukewarm air from the vents and the compressor running constantly. Common causes are a faulty defrost control board or timer, a stuck reversing valve (which flips the system to cooling mode temporarily to defrost), a bad defrost thermostat or sensor, or a refrigerant leak that alters coil temperature. An HVAC technician can diagnose the failed component, replace the board, sensor, or valve, and verify proper defrost cycling before ice damages the compressor.
Waarom dit veel voorkomt in Torrevieja
Torrevieja's summer temperatures regularly exceed 35°C with high relative humidity from the salt lakes, creating a particularly oppressive combination that makes AC failure critical. Outdoor condenser units on sea-facing or lakeside balconies suffer accelerated corrosion from the saline aerosol. AC filters require cleaning 3–4 times per season due to salt and dust loading.
