Navien in Martinez

Navien heating and cooling in Martinez.

Martinez is an older town at heart, with Victorians and craftsman homes near the historic downtown and the waterfront, plus newer homes spreading into Alhambra Valley and the hills. The older homes near downtown usually converted from a tank in tight spaces, while the Alhambra Valley homes tend to be larger and newer.

I service Navien condensing units across Martinez. On the older downtown homes the recurring issue is a conversion that kept the original gas line and forced the venting through the nearest wall. On the newer valley homes it is sizing and condensate routing. This is Diablo Valley, warm inland summers and hard water, and the hard water ages a heat exchanger here.

We run water heater and HVAC work through our division Bay Area HVAC Service. EPA Section 608 Universal certified, CSLB #1136642, the $75 diagnostic is waived with the repair, you get a written quote first, and we are out 7 days a week.

Common repairs we do

What we close on the truck.

  • Tight-space venting faults on downtown Victorians. Older Martinez homes near downtown have the tankless squeezed into a small space with venting forced through the shortest wall path. That can put the terminations out of spec and cause an air or exhaust fault. I check the intake and exhaust lengths and correct the routing.
  • Carried-over gas line on tank conversions. Downtown conversions often kept the original half-inch gas line. The Navien starves under full fire and faults on ignition or flame loss. I test gas pressure while it fires and upsize the branch where needed.
  • Scale from hard inland water. Martinez water is hard and scales the exchanger if it is not flushed yearly. Output drops, then a temperature fault. I descale with a circulation pump and add isolation valves where the install left none.

FAQ

Navien in Martinez questions, answered.

  • How long does it take you to reach Martinez from San Ramon
    It is a straightforward run up the valley. We usually route through Pleasant Hill and Concord, both neighbors of Martinez, so it stays efficient. We confirm a real arrival window.
  • My downtown Victorian has the tankless in a tight closet. Can you still service it
    Yes. Tight installs are common in Martinez's older homes. The usual issue is venting forced through the nearest wall, which can put it out of spec. I check the routing and correct it, with a written quote first.
  • Is annual descaling needed in Martinez
    Yes. The hard inland water here scales the heat exchanger within a year. Annual descaling keeps efficiency up and the warranty valid, and we can put you on a reminder.
