Pool heater repair in Lafayette, Moraga & Orinda
Lamorinda evenings cool off fast, so a heater that will not light shortens your season in a hurry. Heaters throw error codes for a reason, and most of them point at something small — pressure, gas or ignition. We read the fault before we replace anything.
CSLB License #1153587 · Serving Lamorinda & the surrounding areas · The owner answers personally.
What you're probably seeing
It ignites, then shuts off
Almost always low flow or a dirty filter tripping the pressure switch, not a dead heater.
No ignition at all
Igniter, gas valve or flame sensor. We test the sequence instead of guessing at parts.
Error code on the display
Every code narrows it down. We translate it and show you what it means for cost.
Heats slowly or not to temperature
Scaled heat exchanger, undersized run time or a heater too small for the pool.
What the work covers
- Igniter, flame sensor, thermostat and pressure switch replacement
- Gas valve and burner tray cleaning or replacement
- Heat exchanger descaling and leak assessment
- Flow and filter corrections so the heater stops short-cycling
- Season opening heater checks before you need it
How we handle it
1. Read the fault
We pull the code, test the ignition sequence and check flow and gas pressure.
2. Flat written quote
You see the part, the price and whether the heater is worth repairing at its age.
3. Repair and test
We run a full heat cycle and confirm the heater holds temperature before we leave.

Questions we hear a lot
- Why does my pool heater turn on then shut off?
- That is short-cycling and it is usually a flow problem: a dirty filter, a clogged basket or a failing pump keeps the pressure switch from staying closed. Fixing flow fixes the heater more often than a new part does.
- Do you repair spa heaters too?
- Yes — combination pool and spa heaters are the most common setup in Lafayette, Moraga and Orinda, and we service both sides.
- Is it worth repairing an older heater?
- If the heat exchanger is sound, yes. When the exchanger is corroded through, we say so and price a replacement instead of selling you repeat repairs.
- Can you check my heater before summer?
- That is the best time to call. A pre-season check catches ignition and pressure faults before the first warm weekend.
