Our condenser trips the breaker on hot afternoons. What is going on?

A failing start or run capacitor, a compressor drawing high amps, or a dirty coil pushing head pressure up can each do it. We measure the amp draw and pressures under load before we name the part.

Should a 25-year-old Dana Estates system be repaired or replaced?

It depends on the failure. A capacitor or contactor on an old condenser is still a sensible repair. A seized compressor or a coil leak on R-22 equipment is usually where replacement wins, and we show you both numbers.

Can you fix a refrigerant leak instead of just adding more?

Yes, that is how we work. ADRIUM is EPA 608 Universal certified. We find the leak with nitrogen and an electronic detector, repair it, pull a vacuum and weigh the charge in, rather than topping off a system that will be low again by August.

AC Repair in Concord

AC Repair in Concord.

Concord is an air conditioning town. Summer afternoons sit in the low to mid 90s and top 100 in a heat wave, and that load falls on mid-century tract houses around Dana Estates, Sun Terrace and the Crossings. The typical layout is a single-story home with the furnace in a hall closet or the garage, the condenser on a side-yard pad, and ductwork nobody has touched since it went in.

On the east side, Clayton Valley and Crystyl Ranch run newer and larger, mostly two-story homes on one system with zone dampers. There a hot upstairs can trace to the control board or a damper actuator rather than the compressor. Across all four ZIP codes, 94518 to 94521, the $99 diagnostic is credited toward the repair, and the written quote comes before work starts.

Common repairs we handle.

Capacitor failure during a heat wave. Run capacitors weaken with heat, and a string of 100-degree days finishes off the tired ones. The fan stops, or the compressor hums and trips. We test it against its microfarad rating and check the contactor points while we are there.
Side-yard condenser starved for air. A side-yard pad often sits in a narrow gap between the house and a fence. Airflow around the coil drops, head pressure climbs and the compressor runs hot. We clean the coil and measure pressures under load.
Original ducts losing cooled air. Ductwork stapled up decades ago comes apart at the joints, and some of the cooling ends up in the attic or garage. We compare the temperature at the registers with the split across the coil to show you where it is going.
Zone board fault in a Crystyl Ranch two-story. When the upstairs thermostat calls and nothing changes, we check whether the zone board sends the signal and whether the damper opens. A failed board or actuator is a straightforward swap once the meter confirms it.
