Pool Heater Not Heating in Coronado, CA
A Coronado pool showing a pool heater that will not heat usually has a short list of likely causes. No heat, short cycling, or an error code usually points to ignition, gas or airflow, or a scaled heat exchanger. Coronado sits in the Coastal part of the county, where the wear pattern is corrosive year-round salt air on some of the oldest original plaster in the county. A specialist in the Refresh Pool Pros network can diagnose it on site in Coronado and quote the fix in writing before any work starts.
