How quickly can you get to Orinda from San Ramon?

Quickly. We come over through Lafayette on the 24, a short drive, and we are often already working in Lafayette, Walnut Creek, or down in Berkeley and Piedmont the same or next day.

I have a large home. Is one Cooper&Hunter outdoor unit enough?

It depends on total load. A multi-zone condenser can run several heads, but each head and the outdoor unit have capacity limits, and an Orinda estate often needs two outdoor systems. We do a room-by-room load and size it honestly rather than overload one unit.

One of my zones quit but the others still work. Is that the compressor?

No. If the compressor were dead, every zone would stop. One dead zone on a multi-head system is a wiring, board, or flare issue at that specific head, which is a smaller fix. We isolate it on site.

Cooper&Hunter in Orinda

Cooper&Hunter heating and cooling in Orinda.

Orinda sits in a warm inland pocket behind the hills, with a lot of larger 1950s through 1970s homes on wooded lots. Many were built with gas furnaces but no cooling, and on the bigger houses owners go to multi-zone Cooper&Hunter systems to cool several rooms without tearing into the ductwork.

We service these systems across Orinda. The summers here run hot and still, so the cooling side gets worked. Cooper&Hunter is a budget line that does well when it is installed and charged correctly. The watch-item I am honest about is parts, slower to source than the premium ductless brands, so I confirm availability before any ordered repair.

ADRIUM runs HVAC through Bay Area HVAC Service. I am EPA 608 Universal certified, the $75 diagnostic is waived with the repair, quotes are written, and we are out 7 days a week.

Common repairs we do

What we close on the truck.

Flare leak on one zone of a multi-head system. On Orinda's multi-zone Cooper&Hunter setups, one head can lose cooling while the others are fine, and the cause is almost always a flare leak on that branch. We isolate the leaking zone, re-flare the joint, and recharge the whole system to weight since a multi-zone shares one charge.
Zone head not responding on a multi-zone unit. A single indoor head goes dead while the rest run, usually a wiring fault at that head or its own control board. We trace the interconnect to that zone, check the terminals, and isolate whether it is wiring or a board before quoting.
Condenser overheating under summer load. Orinda's hot afternoons push the outdoor unit hard, and a fouled coil or weak fan capacitor makes it trip on high pressure. Pollen and debris off the wooded lots clog the coil fast. We clean it, test the fan and capacitor, and verify it holds pressure on a hot day.
