My Montclair house has no ducts. Will you repair a ductless system someone else installed?

Yes. We work on ductless systems no matter who put them in. The model numbers for the outdoor unit and each head are on labels, and having them when you book helps. ADRIUM holds EPA 608 Universal certification for recovering and recharging refrigerant.

Is cooling worth it in a Rockridge house that stays mild most of the summer?

For many owners it covers a handful of hot days, not a season. A ductless heat pump makes sense because it also heats, and heat is what an Oakland house needs most. If you already have one and it struggles on those days, we check the charge and the coils first.

What does the $99 cover on an Oakland AC call?

It covers our technician's full diagnosis of the system, and the $99 is credited toward the repair if you go ahead. You get a written quote with one total price before anything starts.

AC Repair in Oakland

AC Repair in Oakland.

Oakland is a heating town first. The flats around Temescal, Grand Lake and Adams Point rarely see a punishing summer afternoon, and the hills sit just above the fog. Rockridge and Crocker Highlands are largely 1910s and 1920s houses, and Montclair runs from the 1920s into the 60s on steep lots. Many of these homes, especially in the hills, have no ductwork at all.

So a lot of Oakland AC repair is ductless repair: wall heads fed by an outdoor unit set wherever a steep lot allowed. The faults belong to that type, from flare-fitting leaks to failed drain pumps and communication errors between the heads and the outdoor unit. We read the error codes first, test from there, and give you a written quote before any work starts.

Common repairs we handle.

Communication error between a head and the outdoor unit. When a ductless head blinks a code and the outdoor unit refuses to start, the cause is often the control wiring between them, a failed board, or a loose connection at the terminal block. We check the signal voltage at both ends before ordering a board.
Slow leak at a flare fitting on the line set. Ductless line sets join at flare fittings, and a flare that was not torqued right can leak slowly for years. We pressure-test the lines with nitrogen, remake the flare, pull a deep vacuum and weigh the charge back in.
Coil above a basement furnace icing up. Where cooling was added to a basement furnace, the coil depends on that furnace's blower and on ducts laid out for heat. A clogged filter or a weak blower motor freezes it. We clear the ice, check airflow and charge, and fix the cause.
Wall head dripping water into the room. A ductless head that drips has a clogged drain, a kinked drain hose, or a head hung slightly out of level. We clear and flush the drain, check the slope, and pour water through it before we leave.
