How far is Oakland from your San Ramon base?

It is a straight run over the 24 through Orinda or up 580, about half an hour outside commute hours. We cover Oakland along with Piedmont and Berkeley, so we are out that way regularly.

My Oakland flat has only a floor furnace. Can a Cooper&Hunter heat the whole place?

A single head heats the room it is in well, but an old railroad-style flat with closed rooms needs a head per zone or it will not reach the back bedrooms. We walk the layout and tell you honestly how many zones it takes to heat the whole unit.

The heat pump ices up outside in winter. Is that normal?

A little frost that clears on the defrost cycle is normal. Solid ice that stays on the coil is not, and it usually means a failed defrost sensor or board, or a low charge. We test it rather than let it keep struggling.

Cooper&Hunter in Oakland

Cooper&Hunter heating and cooling in Oakland.

Oakland's housing runs from old Craftsman and Victorian homes in the flats, most with no ducts and a single floor furnace, to hillside houses above the 580. Cooper&Hunter ductless heads are a common budget retrofit in the flats where there is no place to run ductwork and an old floor furnace is the only heat.

We service Cooper&Hunter across Oakland. The climate is bay-moderated, so cooling load is light, but the heat-pump heating gets real use in the cool, damp months. Cooper&Hunter is fine when charged and installed right. The honest watch-item is parts availability versus the premium lines, which I flag on any repair so you are not stuck waiting.

ADRIUM handles HVAC through Bay Area HVAC Service. I am EPA 608 Universal certified, the $75 diagnostic is waived with the repair, you get a written quote, and we work 7 days.

Common repairs we do

What we close on the truck.

Flare leak on long Craftsman linesets. Old Oakland bungalows often need a long lineset to reach a discreet outdoor spot, and the flare fittings are where Cooper&Hunter loses charge. A slow leak shows as weak heating in winter, not just weak cooling. We detect the joint, re-flare, evacuate, and weigh in the correct charge.
Defrost board fault in heat mode. In Oakland's damp cool season the outdoor coil frosts and the unit runs a defrost cycle. A failing defrost sensor or board leaves ice on the coil and kills heating output. We test the sensor and board, and where the board is the fault I tell you the real Cooper&Hunter lead time up front.
Indoor head not heating after a power blip. After a PG&E outage the head sometimes comes back stuck or showing a fault. Often it is a reset or a tripped breaker, sometimes a control board that did not survive the surge. We diagnose it on site rather than guess.
