Do you charge extra to drive to Milpitas from San Ramon?

No. We run down 680 through Fremont to Milpitas as part of our normal South Bay route, so it is the same flat diagnostic and no travel surcharge. We also cover San Jose and Santa Clara on the same trips.

My Cooper&Hunter cools weak only on hot days. Is the compressor dying?

Usually not. Weak cooling that only shows up on the hottest Milpitas afternoons points to a low charge from a slow flare leak, not a failed compressor. We pressure test, fix the leak, and recharge to the weighed-in spec.

Can you add a second zone to my existing Cooper&Hunter system?

If your outdoor unit is a multi-zone model with a spare port, yes. If it is a single-zone condenser, it cannot take a second head and we would quote a separate system. We confirm the model and capacity before quoting.

Cooper&Hunter in Milpitas

Cooper&Hunter heating and cooling in Milpitas.

Milpitas has a lot of 1970s and 1980s tract homes plus newer townhome stacks near the Great Mall, and a fair number of them run Cooper&Hunter ductless heads instead of a full duct system. We service those units across the city, single-zone bedroom installs and the multi-zone setups people add when they finish a garage or a back room.

Cooper&Hunter is a budget ductless line. When the install is clean and the charge is right, it runs fine for years. I am straight with people about the watch-item, which is parts. Compared to the premium ductless brands, a board or a specific valve can take longer to source, so on a no-cool call I check the easy and common failures first before we wait on a part.

ADRIUM runs HVAC through our division Bay Area HVAC Service. I am EPA Section 608 Universal certified, so any refrigerant work is done to code. The $75 diagnostic is waived with the repair, you get a written quote, and we work 7 days.

Common repairs we do

What we close on the truck.

Flare fitting leak at the lineset. On Cooper&Hunter the flare connections at the indoor head and the outdoor unit are the most common leak point. Milpitas gets warm afternoons off the valley floor, so a slow flare leak shows up as weak cooling by mid-summer. We find it with nitrogen and electronic detection, re-flare or replace the fitting, evacuate, and weigh in the exact charge.
Outdoor PCB control board failure. The outdoor control board can fail and throw a communication or compressor fault. This is the spot where Cooper&Hunter parts lead time bites. We diagnose the board against the error code, and if it needs replacing I tell you the real availability before you sit without cooling.
Indoor coil temperature sensor drift. The little thermistor clipped to the indoor coil drifts and the head either short-cycles or freezes the coil. It is a cheap part and a quick fix once it is confirmed with a meter, and it is a far more common cause of poor cooling than a dead compressor.
