Pool Heater Not Heating in Rancho San Diego, CA
No heat, short cycling, or an error code usually points to ignition, gas or airflow, or a scaled heat exchanger. In Rancho San Diego, that is worth diagnosing before it turns into a bigger repair. Because Rancho San Diego pools contend with very hard Otay Water District water scaling equipment, plus aging polybutylene pool plumbing, a technician here checks a slightly different list than one at the coast would. Call and we will connect you with a Rancho San Diego pool pro who finds the real cause, not a guess.
