Do you actually cover Half Moon Bay, or is it out of your normal range?

Half Moon Bay is our anchor for the whole Coastside, and that includes Montara, Moss Beach, and El Granada on the same route. Our technician is based on the Peninsula, not driving out from San Ramon just for this stretch. Call (925) 999-4095 and we'll confirm where you fall on the schedule.

Does the salt air out here really change how a Tempstar system holds up?

Yes, noticeably. Coil fins, contactor points, and pressure switch hoses corrode faster on the coast than they do even a few miles inland, so equipment out here can show its age earlier than the same unit would somewhere like San Ramon or Redwood City.

What does the $99 diagnostic check for on a Coastside call?

I check for corrosion on the coil, contactor, and pressure switch components specifically, since that's the difference-maker out here, along with the standard fault code read. You get a written quote after that, and the $99 comes off the bill if you book the repair.

Tempstar in Half Moon Bay

Tempstar in Half Moon Bay kitchens.

Half Moon Bay is our anchor for the whole Coastside, and that covers Montara, Moss Beach, and El Granada right along with the town itself. Cottages near Main Street and the harbor tend to run older Tempstar furnaces with barely any AC to speak of, since the marine layer keeps this stretch of coast cool enough that cooling was never much of a priority when the equipment went in. Newer homes up in the bluff neighborhoods increasingly run heat pumps instead, chasing both heating and the occasional need for cooling on the rare clear, warm days.

Salt air off the ocean here is heavier and more constant than what I see on the bay side of the Peninsula, and it goes after outdoor equipment fast. Aluminum coil fins pit and corrode, contactor points pit ahead of schedule, and control board housings that would stay dry for years inland let moisture in here within a handful of seasons. On the furnace side near Main Street, most of my calls are heating-only, given how little the AC actually runs, but I check the pressure switch hose routing for corrosion on every one of them, since that's where I find problems building before they show up as a lockout.

ADRIUM Service Solutions runs out of San Ramon and keeps a technician based on the Peninsula, and Half Moon Bay along with Montara, Moss Beach, and El Granada all get that same local coverage rather than a special trip out to the coast. The diagnostic is $99 and it's waived if you book the repair with us that visit. You get a written quote before anything starts, we hold EPA Section 608 Universal certification and CSLB license 1136642, and we're on call seven days a week.

Common repairs we do

What we close on the truck.

Condenser Coil and Contactor Corrosion from Ocean Salt Air. Ocean salt air along the Coastside corrodes an outdoor condenser faster than anything I see on the bay side of the Peninsula. The aluminum fins pit and lose surface area for heat transfer, and the contactor points corrode and pit ahead of a normal service schedule, which shows up as a system that runs weak or a compressor that hesitates to start. A five-year-old unit out here can test like a much older one internally. I check fin condition and contactor contact surface on every Half Moon Bay cooling call before I look at the refrigerant circuit.
Pressure Switch Hose Corrosion on Furnaces Near the Harbor. The rubber pressure switch hose on a Coastside furnace takes on moisture and salt exposure faster than the same part inland, and a hose that's started to crack or corrode at the fitting causes an intermittent pressure switch fault that looks like an inducer problem until I actually trace the hose. Furnaces near Main Street and the harbor see this more than the newer bluff-neighborhood installs, since a lot of that older equipment has been in place through more salt-air seasons. I check the hose and fitting on every lockout call before I condemn the switch itself.
Heat Pump Defrost Board Faults in the Marine Layer. Heat pumps up in the bluff neighborhoods run through a heavier, more constant marine layer than most Peninsula heat pump installs ever see, and that humidity load makes the defrost cycle work harder to keep the outdoor coil clear of ice. A defrost board that's starting to fail shows up as a coil that stays iced over too long or defrosts too often, cutting into heating capacity on cold, damp mornings. I check the defrost sensor reading against the board's trigger point before replacing the board outright.
