Furnace short-cycling on and off — Benidorm, Valencian Community
A furnace that starts, runs for only a few minutes, shuts off, and restarts repeatedly is short-cycling. This wastes energy, strains the blower motor and heat exchanger, and leaves the house underheated. Common causes are a dirty air filter restricting airflow, an overheating limit switch tripping, a malfunctioning flame sensor, a thermostat placed near a heat source, or an oversized unit. An HVAC technician can diagnose the trigger, clean or replace the flame sensor, check the heat exchanger, and ensure proper airflow.
Waarom dit veel voorkomt in Benidorm
Summer occupancy near saturation makes AC failures in July–August true emergencies in Benidorm's packed towers, and salt-laden sea air corrodes outdoor condensers mounted high on exposed façades. F-Gas certified technicians are required for refrigerant work, and high-rise installation often demands rope-access or crane lifts that add cost and lead time.
