How quickly can you get to Livermore from San Ramon

Quickly. We come straight down the 580 corridor, and Livermore borders Pleasanton and Dublin, which sit between us and you. Next-day and same-week visits are usually easy.

Livermore water seems very hard. How often should I descale

At least once a year, and Livermore is hard enough that I sometimes recommend checking it a little sooner. Annual descaling keeps efficiency up and the warranty valid, and we can set you on a reminder.

My south-side home is newer but the tankless already faults. Why

On fast-built tracts the venting and condensate were sometimes done to the minimum. A few years in, those shortcuts show up as clogs or air faults. I find which one and correct it, with a written quote first.

Navien in Livermore

Navien heating and cooling in Livermore.

Livermore mixes older homes near the historic downtown and the wine country edges with large newer developments on the south side toward the vineyards. The older homes often converted from a tank and the newer tracts came with factory tankless units. This is the hottest, driest corner of the Tri-Valley, and the water is hard.

Navien condensing units serve Livermore well when sized and installed correctly. In the newer south-side tracts the venting and condensate were sometimes done to the minimum during fast construction. In the older downtown homes the recurring issue is the carried-over gas line. The Navien efficiency holds only when the gas, venting, and condensate are right.

The hard Livermore water is the main thing that scales a heat exchanger here, so descaling matters. We service through Bay Area HVAC Service. EPA 608 Universal certified, CSLB #1136642, $75 diagnostic waived with the repair, written quotes, and 7 day availability.

Common repairs we do

What we close on the truck.

Heavy scale from hard Livermore water. Livermore has some of the hardest water in the Tri-Valley, and the Navien exchanger scales fast without yearly flushing. The shower goes lukewarm, then a temperature fault. I descale with a circulation pump and check the inlet filter screen for mineral buildup too.
Builder-minimum venting and condensate on south-side tracts. Newer south Livermore homes sometimes had venting and condensate done to the bare minimum. A few years in, the condensate clogs or the vent causes an air fault. I correct the routing and add a neutralizer for the acidic discharge.
Old gas line on downtown conversions. Older homes near downtown converted from a tank often kept the half-inch gas line. The Navien starves under full fire and faults on ignition. I test gas pressure while it fires and upsize the branch where needed.
