Our condenser sits on a slope behind the house. Is that a problem?

It can work fine if the pad is level and firm and the unit has clearance on all sides. We check the level, the drainage around it and the line set. If the pad has sunk, we reset it before the tilt damages the lines or the compressor mounts.

Do you cover El Sobrante Manor and the triangle near Valley View Road?

Yes, and the rest of El Sobrante, from the downtown stretch of San Pablo Dam Road to the hill streets above it. Let us know if reaching the outdoor unit involves stairs or a gate.

Is our 1990s system worth repairing?

It depends on the part and the refrigerant. A capacitor, contactor, fan motor or drain problem is worth fixing at almost any age. A system from the 1990s likely runs on R-22, so a leak or a compressor failure is where we price the repair against replacement and give you both numbers. ADRIUM holds EPA 608 Universal certification for the refrigerant work.

AC Repair in El Sobrante

AC Repair in El Sobrante.

Roughly three quarters of El Sobrante's housing was built between 1940 and 1979, in a mix of old ranchettes, later subdivisions, and apartment and condo buildings. Homes line San Pablo Dam Road and Appian Way and climb into the hills above. Little of it was built with cooling, so the systems vary house by house: a condenser added to a furnace, a ductless heat pump, or a split system serving one condo.

On a hillside lot the outdoor unit often sits on a small pad cut into the slope or on a deck. Pads settle, and a tilted condenser strains its refrigerant lines and drains poorly. We check the pad and the line set along with the electrical parts. Our technician's base is in Benicia, and El Sobrante is part of that area. Every visit opens with the $99 diagnostic, credited toward the repair.

Common repairs we handle.

Settled pad tilting the condenser. When a pad on a slope sinks at one corner, the unit leans, the fan runs off balance, and the line set can kink or rub. We level the unit, inspect the lines and their insulation for damage, and look for oil stains that mark a leak.
Pinhole leak in an add-on coil. Indoor coils corrode from the inside over the years and develop pinhole leaks, and cooling fades as the charge drops. We pressure-test with nitrogen, locate the leak, and quote the coil replacement or repair before any refrigerant goes back in.
Cooling that will not start from the thermostat. In older homes the thermostat cable may be an old run reused for a newer system, and a broken conductor or a failed transformer leaves the condenser without a call. We meter the 24-volt circuit end to end and repair the break or the part that failed.
Ductless heat pump flashing a fault. Ductless systems report faults with codes or blinking lights on the indoor head. We read the code, then check the sensors, the communication wiring between the units and the outdoor board. Many of these faults are sensors or wiring rather than the compressor.
