The service
A proper flush and descale. That's it.
San Diego's hard water leaves mineral scale inside your tankless unit's heat exchanger. Left alone, it chokes efficiency, makes the unit work harder, and can void your warranty. An annual cleaning clears it out — and it's all we do.
How it works
Four steps, in order.
- 01
Inspect
We check the unit, connections, and any error or fault codes before touching anything.
- 02
Flush & descale
A full circulation flush dissolves the hard-water scale built up inside the heat exchanger.
- 03
Clean filters & components
Inlet filter and key components are cleaned so water and gas flow the way they should.
- 04
Verify & advise
We confirm the unit runs clean and quiet, and give you honest, no-pressure recommendations.

Why yearly
Skip it, and the warranty goes with it.
Manufacturers require documented annual maintenance to honor a warranty claim. If your unit fails and you haven't kept up service, you could be buying a whole new heater. Yearly cleaning is the cheap insurance — and we remind you when it's due.
