How long does it take you to reach Moraga from San Ramon?

We come over through Lafayette or down through Orinda, both short hops, so Moraga is an easy run for us. We are often already in Orinda or Walnut Creek the same or next day, so scheduling is quick.

My house has wall furnaces and no ducts. Can a Cooper&Hunter still heat in winter?

Yes. These are heat pumps, so the same head that cools in summer heats in winter, which is a real upgrade over an old gas wall furnace. We check that the unit is sized for the room and that the heat mode actually holds temperature on a cold morning.

The head freezes up and stops cooling. What causes that?

On Cooper&Hunter a frozen indoor coil is usually a low charge from a flare leak or a dirty filter and coil, not the compressor. We check airflow and filter first, then pressure test for a leak.

Cooper&Hunter in Moraga

Cooper&Hunter heating and cooling in Moraga.

Moraga sits inland behind the Oakland hills, so summers run hot and still in the afternoon. A lot of the 1960s and 1970s homes here were built with wall furnaces and no ducts, so when owners want real cooling they go ductless. Cooper&Hunter shows up often because it is the budget way to put cooling in a home that never had it.

I service these systems across Moraga, both the single-head retrofits in a bedroom and the multi-zone jobs in the larger hillside houses. Cooper&Hunter does the job when it is charged and installed right. The honest watch-item is parts, since they are slower to source than the premium ductless lines, so on a repair I confirm the part is available before anyone commits.

ADRIUM handles 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 joint leak from heat cycling. Moraga's hot, dry inland summers heat-cycle the linesets hard, and on Cooper&Hunter the flare fittings are where that movement opens a leak. A flare that was just slightly under-torqued at install will weep over a season or two. We re-flare with the right tool, evacuate, and charge by weight.
Condensate drain backup on wall heads. On retrofit installs the indoor head drains by gravity, and a long shallow drain line clogs with algae and overflows onto the wall. We clear the line, flush it, and reset the slope or add a small pump if the run is too flat for gravity.
Capacitor and fan motor faults on the outdoor unit. After a few hot seasons the outdoor fan capacitor weakens and the condenser fan struggles, which makes the system trip on high pressure on the hottest days. We test the capacitor and motor, replace the failed part, and verify pressures under load.
