Furnace short-cycling on and off — Torrevieja, 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 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.
