Pool Heater Not Heating in Poway, CA
When a Poway pool has a pool heater that will not heat, the fix is usually straightforward once the cause is found. No heat, short cycling, or an error code usually points to ignition, gas or airflow, or a scaled heat exchanger. Because Poway pools contend with hard municipal water and well-fed equipment wear across Poway's larger ranch lots, a technician here checks a slightly different list than one at the coast would. A specialist in the Refresh Pool Pros network can diagnose it on site in Poway and quote the fix in writing before any work starts.

What to check before you call
