Mitsubishi in Palo Alto
Mitsubishi heating and cooling in Palo Alto.
Palo Alto runs from the older Craftsman and Spanish homes around Professorville and Old Palo Alto to the big Eichler tracts in the south end. The Eichlers and the older homes share a problem, no good place for ducts, so Mitsubishi mini-splits are common. Owners want quiet, efficient heating and cooling without opening up a flat roof or a finished plaster ceiling.
We service Mitsubishi Electric M-Series and MXZ multi-zone across Palo Alto. The Mid-Peninsula climate is mild and the loads are light most of the year, so a system that acts up is usually showing a specific fault rather than being run into the ground.
I diagnose by the Mitsubishi fault code, and on a multi-zone a dead head is that head's board or sensor before the condenser. We completed Mitsubishi factory training, hold EPA 608 Universal and CSLB licensing, give written quotes, and waive the $75 diagnostic with the repair.
Common repairs we do
What we close on the truck.
- Eichler head E6 or comm dropout. South Palo Alto Eichlers run long, exposed linesets and wiring, so the S1-S2-S3 communication connection is a frequent failure that throws an E6 and drops the head. I trace and re-terminate the comm wiring instead of replacing boards on a hunch.
- Linear expansion valve fault on an M-Series. An older Palo Alto single-zone that overheats or undercools one room often has a sticking LEV. I read the head's operating data, confirm the valve is not stepping correctly, and replace the coil or valve body rather than chasing it with refrigerant.
- Condensate pump failure on a wall-mount with a pump kit. Where a head was installed below the drain point and uses a condensate pump, the pump fails or clogs and the float shuts the head off. I service or replace the pump and verify the drain path so the unit stays running through warm spells.

FAQ
Mitsubishi in Palo Alto questions, answered.
-
How long does it take you to reach Palo Alto from San Ramon?
Palo Alto is one of our longer drives. From San Ramon we take the 680 down and cross over, roughly 45 to 60 minutes with bridge and 101 traffic. If you are near Atherton, Los Altos Hills, or Saratoga we route the same way and try to group the trip. -
Can a Mitsubishi mini-split go into my Eichler without cutting the roof?
Yes. The heads mount on the walls and the lineset runs outside to the condenser, so we leave the flat roof and the slab alone. We can run a multi-zone if you want several rooms covered from one outdoor unit. -
Do you waive the diagnostic if I have the repair done?
Yes. The diagnostic is $75 and we waive it when you approve the repair. The written quote comes before any work.
