Is San Bruno inside your normal coverage, given it's up near the airport?

Yes. We have a technician based on the Peninsula in San Mateo County covering San Bruno along with South San Francisco, Millbrae, and Pacifica. Being near SFO doesn't change our coverage.

My outdoor unit runs constantly on windy afternoons. Is that a problem?

On the exposed hill streets in San Bruno, wind across the coil can make the unit work harder and run longer, which isn't automatically a fault. I check the actual fault codes and head pressure readings before assuming something's broken versus the unit just fighting the wind.

The ductless head someone installed in my converted garage never keeps up. Can that be fixed?

Usually that's a sizing or airflow issue from the original retrofit, not a failing unit. I check the load against the head's capacity and the line set run before recommending a repair or a different-sized head.

Daikin in San Bruno

Daikin in San Bruno kitchens.

San Bruno sits right under the flight path and the wind funnel off SFO, and the hill neighborhoods like Rollingwood and Portola Highlands catch a steady, cold wind most afternoons even when it's warm down in the flats. A Daikin heat pump working against that kind of wind load on the outdoor unit runs longer cycles than the same system would in a sheltered yard.

Older San Bruno homes from the 1950s and 60s often added a Daikin ductless head later for a bedroom or converted garage that the original heating never reached well. Those retrofits depend on a clean line set run and a properly sized head, and I see a fair number where the head is oversized or undersized for the room it landed in.

We cover San Bruno with a technician based on the Peninsula in San Mateo County, so this isn't a long-drive city for us. The $99 diagnostic is credited toward the repair, and you get a written quote before I do any work. We're CSLB #1136642, EPA 608 certified, and we run HVAC through Bay Area HVAC Service, 7 days a week.

Common repairs we do

What we close on the truck.

Outdoor unit wind exposure on the hill streets. On the exposed hill lots in San Bruno, steady wind across the outdoor unit can disrupt the airflow pattern the coil depends on, and I check for a fault code tied to airflow or high head pressure before assuming a mechanical failure. Sometimes the fix is a wind baffle or repositioning the unit, not a repair.
Mismatched head size on garage and bedroom retrofits. A lot of San Bruno retrofits put in a Daikin head sized off a rule of thumb instead of an actual load calculation, and the room either overshoots temperature and short cycles or never quite catches up. I check the EEV steps and runtime pattern against the room size before deciding whether it's a sizing issue or a controls fault.
Refrigerant line set corrosion on older retrofit runs. Some of the older ductless retrofits in San Bruno used line set insulation that's degraded after years in the coastal damp, and moisture reaching the copper causes slow leaks at the flare fittings. I leak-check the fittings under the insulation before charging, since topping off a slow leak just brings the same complaint back.
