We rent a San Pablo row house with a Navien. Who should call about repairs?

Either of you can call. We diagnose with the tenant home and send the written quote to the owner or manager who approves it. Everyone sees the same findings.

Is a Navien combi-boiler a good fit for a small San Pablo house?

It can be, if the house uses hot-water heat or will. A combi-boiler handles space heating and domestic hot water in one wall-mounted unit, which saves room. We look at the heating system, the gas line and the vent path before recommending it.

Our Navien shows an error and won't restart. Should we keep pressing reset?

No. One reset is fine, but repeated resets on an ignition fault are not safe, because each one sends gas to a burner that is not lighting properly. Write down the code and call. The code tells us where to start.

Navien in San Pablo

Navien heating and cooling in San Pablo.

San Pablo sits on a plain between the north end of the Berkeley Hills and San Pablo Bay. More of its housing went up in the 1940s through the 1960s than in any other era, and the mix includes small single-family houses, row houses and apartment buildings. A Navien in one of those homes often shares a small gas line with a furnace and a range, and it has to vent through a wall close to a neighbor, a fence or a window.

Those two details, gas supply and vent clearances, explain many Navien faults in older, tighter housing. The water is EBMUD, soft to moderate, so scale is less of a worry than elsewhere, though the inlet filter still collects sediment.

Our technician covering San Pablo is based in Benicia. A $99 diagnostic, credited toward the repair, comes first, and the quote is written before any work. For rentals, we send it to whoever approves the job.

Common repairs we handle.

Ignition lockout on a shared, undersized gas line. When the furnace and the Navien fire at once on a small line, pressure drops and the tankless locks out. We measure gas pressure under load, check the regulator and the pipe size, and explain what it takes to fix the supply.
Inlet filter clogged and water running lukewarm. Sediment from old pipes or street work collects on the Navien inlet screen. Flow drops, the unit fires weakly or not at all, and a flow code may appear. We clean the screen, check the flow sensor, and test the outlet temperature at a tap.
Exhaust vent too close to a window or fence. On a small lot the vent can end up near a window, a fence or a walkway. Exhaust recirculating into the intake causes combustion faults, and condensate drip can stain a wall. We check the termination against the installation manual and propose a fix.
