How far is Saratoga from your San Ramon base

It is one of our longer runs. From San Ramon I take 680 down through Fremont and Milpitas, then across the South Bay toward Saratoga, usually around fifty minutes to an hour. We still service it with no travel surcharge.

My estate has two tankless units, can you handle a cascade

Yes. Twin Navien units in cascade are common in larger Saratoga homes. I check the controller and load sharing along with each unit, since an imbalanced cascade is a frequent cause of faults and uneven wear on these big systems.

We are on well water with a softener, does that change service

It does. A working softener slows scaling, but a neglected one makes it worse than city water. When I descale I test your softened water hardness so we address the real cause and set the right interval for your Saratoga home.

Navien in Saratoga

Navien heating and cooling in Saratoga.

Saratoga is large custom homes and estates on wooded foothill lots, many with multiple bathrooms spread across a big footprint and detached structures. These homes lean on recirculation, and some run more than one tankless or a cascade to keep up with demand. A Navien serving a long way to far wings is doing real work here.

We service Navien condensing tankless throughout Saratoga. The foothill tree cover collects debris on vent terminations, and the long internal plumbing runs make recirculation setup critical. Some homes are on well water with softeners, which changes the descaling picture, but city-served homes still scale on the usual annual cycle.

ADRIUM handles the larger multi-zone and cascade setups these estates have. On a Saratoga home I check the recirculation, any cascade controls, and the terminations along with water hardness, because the problem is usually in how the system was integrated across a big house, not one failed part.

Common repairs we do

What we close on the truck.

Cascade or twin-unit load imbalance. Larger Saratoga estates sometimes run two Navien units in cascade. A wrong cascade setup makes one unit overwork while the other sits idle, causing faults and uneven wear. I check the cascade wiring and load sharing so both units carry their share of the demand.
Debris-blocked foothill vent terminations. Under the Saratoga tree canopy, intake and exhaust terminations collect leaves and webs and the Navien throws air-pressure or exhaust faults. I clear and screen both terminations and confirm the flue path so it does not recur each wet season.
Recirculation running a far-wing loop nonstop. Long runs to far wings tempt an aggressive recirculation setting that fires the unit constantly and wears the fan and igniter. I tune the recirculation schedule and crossover so the unit runs sensible cycles while still delivering hot water to the far fixtures.
