Spa Not Heating in Rancho Bernardo, CA
When a Rancho Bernardo pool has an attached spa that will not heat, the fix is usually straightforward once the cause is found. A spa that will not warm up usually traces to a stuck diverter valve, a heater fault, or an automation setting. Rancho Bernardo runs on City of San Diego at 12-14 gpg, which is hard water. Around here that means aging 1970s-80s pool equipment and plaster nearing the end of service life, and it shows up in problems exactly like this one. The pros we work with cover Rancho Bernardo and can usually get out within the week.
