How far is Piedmont from your San Ramon base?

From San Ramon we take the 24 through the tunnel toward Oakland and Piedmont, usually 30 to 45 minutes with tunnel traffic. Oakland, Berkeley, and Orinda all border Piedmont, so we can often pair the visit with a nearby call.

I don't want ducts cut through my plaster. Can Mitsubishi avoid that?

Yes. Wall-mount heads need only a small lineset penetration, and where you want a room kept clean we can use a concealed ducted head in an attic or soffit with minimal cutting. A multi-zone covers several rooms from one condenser.

What warranty comes with the work?

A full install through our HVAC division carries 10-year parts and 10-year labor. A repair carries a 1-year warranty. Everything is written down before we start.

Mitsubishi in Piedmont

Mitsubishi heating and cooling in Piedmont.

Piedmont is older, stately homes, a lot of 1910s through 1930s estates with plaster walls, multiple floors, and original radiator or wall heat. None of them were built for central air, and the owners do not want ducts torn through finished plaster. Mitsubishi multi-zone ductless is the clean answer, heads in the rooms that matter and a single condenser tucked out of sight.

We service Mitsubishi M-Series and MXZ multi-zone across Piedmont. These older homes usually run multi-zone with several heads across floors, so there are more indoor boards and more communication runs that can drop a single zone. The inner-East-Bay climate is moderate, so the systems mostly handle warm spells and the cold snaps.

I read the fault code and prove the cause before quoting. On a Piedmont multi-zone, a dead head is that head's board or sensor first, not the outdoor unit. ADRIUM is EPA 608 Universal certified, CSLB #1136642, with the HVAC work through our Bay Area HVAC Service division. The $75 diagnostic is waived with repair.

Common repairs we do

What we close on the truck.

One head dark on a multi-floor multi-zone. In Piedmont estates with heads on three floors, a single zone going dead while the rest run is almost always that head's indoor board or sensor. I confirm at the head with the code so the repair lands on the right unit, not on a healthy condenser.
Concealed-duct cassette airflow loss. Some Piedmont installs use Mitsubishi concealed ducted heads in attics or soffits to keep the plaster intact, and a slipped or crushed flex run kills airflow to a room. I check static pressure and the duct path rather than blaming the head's blower.
Reversing valve fault on the heating swap. An estate head that cools fine but will not heat often has a stuck reversing valve or a failed valve solenoid on the condenser. I confirm with the code and the valve operation before replacing, since a low charge can imitate the same complaint.
