How quickly can you reach Dublin from San Ramon

Quickly. Dublin borders San Ramon, with Pleasanton and Livermore right alongside, so it is one of our closest runs. We can usually offer next-day or same-week service.

My East Dublin home is fairly new and the tankless already faults. Why

On newer tracts the venting and condensate were sometimes installed to the minimum during fast construction. 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.

How often does a Dublin tankless need descaling

Once a year. The hard Tri-Valley water scales the heat exchanger within a year. Annual descaling keeps efficiency up and the warranty valid, and we can remind you when it is due.

Navien in Dublin

Navien heating and cooling in Dublin.

Dublin is split between the older west side near the historic district and the large newer developments out east toward Fallon and the Tassajara line. The east-side homes are mostly newer two-stories that came with a tankless unit from the builder, and the west-side homes are older ranches where owners converted from a tank.

Navien condensing units are common in the newer Dublin tracts. When a builder installs a hundred homes quickly, the venting and condensate sometimes get done to the minimum, and a few years in those shortcuts surface as faults. On the older west-side conversions the recurring problem is the carried-over gas line. Either way, the Navien efficiency depends on the gas, venting, and condensate being right.

Dublin is Tri-Valley, hot inland summers and hard water that scales a heat exchanger. We service through Bay Area HVAC Service. EPA 608 Universal certified, CSLB #1136642, $75 diagnostic waived with repair, written quotes, 7 days a week.

Common repairs we do

What we close on the truck.

Builder-grade venting and condensate shortcuts. In the newer East Dublin tracts the venting and condensate were sometimes done to the bare minimum during fast construction. A few years on, the condensate line clogs or the vent terminations cause an air fault. I correct the routing and add a neutralizer where the discharge needs it.
Scale on the heat exchanger. Dublin's hard water scales the Navien exchanger quickly. The first sign is the shower going lukewarm, then a temperature fault. I descale with a pump and verify the isolation valves so it stays easy to maintain.
Old gas line on west-side conversions. West Dublin ranch homes converted from a tank often kept the half-inch gas line. The Navien cannot draw full BTU and faults on ignition under load. I test gas pressure while it fires and upsize the branch where needed.
