How far is Richmond from your San Ramon base

From San Ramon I run 24 toward Oakland then up 80 toward Richmond, usually around forty to forty-five minutes depending on traffic. We cover Richmond including Point Richmond and the El Sobrante side. No travel surcharge.

My outdoor vent and drain hardware looks rusty, is that a problem

Yes. Richmond's salty bay air corrodes that hardware faster than inland. A restricted vent or a leaking condensate fitting causes faults. I replace the termination and fittings and reseal, so it stays sound.

Why does my small home's tankless cut out during a shower

On a small Richmond cottage that is usually the old gas line not delivering full input, or scale in the exchanger. I test gas pressure under full fire and the flow to tell which, with a written quote before any work.

Navien in Richmond

Navien heating and cooling in Richmond.

Richmond has a lot of small wartime and post-war cottages in the flats, older homes in Point Richmond, and hillside houses up toward El Sobrante. The small flat-land homes often have a tankless squeezed into a tiny utility space or on an exterior wall, and the bay-front and industrial-edge air is damp and a little corrosive on outdoor vent and condensate hardware.

We service Navien condensing tankless across Richmond. The salty, humid bay air shortens the life of sidewall terminations and outdoor condensate lines, while the hard water scales the exchanger inside on the usual schedule. My Richmond calls are a mix of corrosion-driven vent work and annual descaling.

ADRIUM checks the combustion path and the gas supply along with water hardness before quoting. On a small Richmond cottage with the unit on an exterior wall, the corroded termination and the undersized gas branch are the two things I find most often behind intermittent faults.

Common repairs we do

What we close on the truck.

Corroded exterior vent and condensate hardware. Richmond's damp, salty bay air corrodes outdoor PVC termination screws, screens, and condensate fittings. The vent gets restricted or the condensate leaks. I replace the termination kit and condensate fittings and reseal the penetration so the unit vents and drains cleanly.
Undersized gas branch on a small cottage. The original gas line in a small wartime Richmond home often cannot feed a high-input Navien. Under full fire the unit starves and throws flame-loss codes. I measure dynamic pressure at the unit and upsize the branch where it is short.
Scale and inlet sediment from old plumbing. Older Richmond homes still have galvanized pipe shedding sediment, plus hard water scaling the exchanger. The inlet filter clogs and output drops. I clean the inlet screen, descale the exchanger, and add isolation valves for easy future service.
