How far is San Leandro from your San Ramon base?

It is a run down 580 over the hills, roughly half an hour off-peak. We cover San Leandro with Oakland, Hayward, and Alameda, so we are in the inner East Bay regularly.

Can a Cooper&Hunter replace my old wall furnace?

Yes, and that is a common upgrade in San Leandro. A ductless head is a heat pump, so it heats in winter and cools in summer where the old wall furnace only heated. We confirm the head is sized for the room and that the heat mode holds on a cold morning.

It heats and cools but takes forever to switch between them. Normal?

A short delay is normal while the reversing valve shifts. A long delay or a failure to switch at all points to a sticking reversing valve solenoid, which is a specific repair. We test it rather than wait it out.

Cooper&Hunter in San Leandro

Cooper&Hunter heating and cooling in San Leandro.

San Leandro is older bungalow neighborhoods like Bal and Broadmoor plus flatland tract homes, much of it built before central air was standard. The bay keeps it mild, but plenty of these homes added a Cooper&Hunter ductless head to cool a bedroom or to replace a tired wall furnace with a heat pump.

We service these systems across San Leandro. The climate is gentle so the units are not stressed hard, but the older homes make for long or awkward linesets where flare leaks begin. Cooper&Hunter is fine when installed and charged right, and the honest watch-item is parts availability versus the premium ductless lines.

ADRIUM runs 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 a long bungalow lineset. San Leandro bungalows often need the lineset run a long way to a discreet outdoor spot, and on Cooper&Hunter the flare fittings at each end are the leak point. We pressure test, re-flare the weeping joint, evacuate, and recharge by weight rather than top off.
Reversing valve stuck between heat and cool. A head that will not switch from cooling to heating, or the reverse, often has a stuck or failing reversing valve solenoid. We test the solenoid and valve to confirm it is the valve and not a control fault before quoting the repair.
Condensate drain overflow on the indoor head. Algae clogs the gravity drain and the head drips inside the wall. We clear and flush the line, check the slope, and add a pump where the run is too flat for gravity to keep up.
