What we fix
- Ignition and pilot systems (gas): no-start and intermittent-start failures traced to the actual failed part — igniter, pilot assembly, or gas valve — not a parts cannon.
- Thermostats and sensors: temperature sensors that drift, thermostats that lie, pressure switches that trip for no good reason. Tested, not guessed.
- Heat exchangers: scale buildup from hard water is the slow killer — flow testing shows whether it's a descale job or a replacement call.
- Control boards and electrical (electric): elements, relays, contactors, and boards — power-event damage diagnosed before anything is ordered.
- Solar plumbing and controllers: panel leaks, connection failures, and controller faults on solar thermal systems.
Repair vs. replace vs. install: different jobs
- This page is repair. Something broke — we find it, quote the fix, and fix it. Diagnostic framing, per-job pricing.
- Need a brand-new heater? That's pool equipment installation — new-unit installs with the install bands, a different job with a different quote.
- Researching costs first? Our cost guides cover the numbers side — repair-vs-replace math and heater cost bands — as the information companion to this service page.
- The 50% rule: repair quote over half of ~$2,800 replacement cost, on a unit past 8-10 years, usually means replace. Under half on a younger unit usually means repair. We show you both numbers.
Frequently asked questions
How much does pool heater repair cost in Orange County?
Electric heater repairs run $200-$1,200, gas heater repairs run $150-$750, and solar heater repairs run $50-$400. The average pool heater repair lands around $460. Simple fixes (sensors, switches, igniters) sit at the low end; heat exchanger work and control board replacements sit at the high end. You approve the exact price before any work starts.
Should I repair my pool heater or replace it?
The 50%-of-replacement-cost rule: if the repair quote is more than half the cost of a new heater (replacement runs about $2,800 installed), replacement usually wins -- especially on units over 8-10 years old. If the repair is well under half and the unit is younger, repair is the smart money. We give you both numbers so the decision is arithmetic, not pressure.
What are the most common pool heater failures?
Ignition and pilot failures on gas heaters, thermostats and temperature sensors drifting or dying, heat exchangers scaling up (hard water is the culprit), pressure switches tripping, and control boards failing after power events. The diagnostic visit identifies which one -- most repairs are one failed part, not a dying heater.
How long does a pool heater repair take?
Most diagnostics plus repairs finish in a single visit: test, identify the failed part, replace it, verify the heater cycles correctly. Jobs waiting on an ordered part get scheduled for the return visit -- you're told the timeline upfront, not after the deposit.
Is repairing a gas heater different from electric or solar?
Yes -- different parts, different skills. Gas heaters fail at ignition components, gas valves, and heat exchangers; electric heaters fail at elements, relays, and contactors; solar systems fail at panels, plumbing connections, and controllers. The diagnostic approach is the same (test before replacing), but the parts and the price bands differ -- which is why the quote is per-heater-type, not one-size-fits-all.
