We only need AC a few weeks a year. Is repairing our old unit worth it?

For a capacitor, contactor or fan motor, yes, those are modest repairs. For a failed compressor on a system that runs a few weeks a year, we price the repair and a replacement in writing and let you weigh them.

Does the furnace in our garage affect the AC?

Yes. On an add-on system the furnace blower moves the cooled air, so a weak blower motor, a dirty wheel or a failed control board stops the cooling too. We test the blower side as part of the AC diagnosis.

Do you cover both 94546 and 94552?

Yes, both ZIP codes, from Castro Valley Village and the flats up to Five Canyons and Palomares Hills. Refrigerant repairs are done under ADRIUM's EPA 608 Universal certification, license CSLB #1136642.

AC Repair in Castro Valley

AC Repair in Castro Valley.

Castro Valley has one of the mildest climates we serve. Marine air through the gap at Hayward keeps most summer afternoons in the high 70s and low 80s, and a large share of the ranch homes around the Village, Proctor and Jensen Ranch never had air conditioning. When AC does get added to one of those houses, the coil sits on the furnace in the garage and shares the original ducts overhead or under the floor.

Five Canyons and Palomares Hills are 1990s and newer hillside tracts with two-story homes, zoned systems and condensers on exposed pads. Those systems bring zone board and damper work along with the usual capacitor and contactor failures. Every visit starts with a $99 diagnostic, credited toward the repair, and a written quote before we touch anything.

Common repairs we handle.

Add-on coil icing over in a flats ranch. A cooling coil added to an older furnace can end up paired with ducts that were sized for heat only. Low airflow lets the coil freeze. We check the filter, the blower speed and the static pressure, then the refrigerant charge.
Original ductwork leaking under the floor. Ducts in the mid-century ranches run overhead or under the floor, and joints that have separated dump cooled air where nobody lives. We check the runs we can reach and tell you what sealing or repair would recover.
Condenser on an exposed Palomares Hills pad. A pad on a hillside lot can sit in full afternoon sun, and a tired capacitor or fan motor gives out under that load. We test both, clean the coil, and check the amp draw after the repair.
Second floor stays warm on a zoned system. The damper serving the upstairs may be stuck, or the zone board has stopped answering that thermostat. We test the board outputs and the actuator, and replace only the one that failed.
