Mitsubishi in Belmont
Belmont splits into two different jobs for us. Down near El Camino Real and Ralston Avenue, the tract homes already have forced-air ductwork from the original furnace and AC, so a Mitsubishi ductless system usually isn't the whole-house answer there, it earns its place on a converted garage or a bonus room the ducts never reached. Up toward Hallmark Drive and the ridge, the lots get steep and the homes are custom, one at a time, and that's where a Mitsubishi multi-zone makes real sense, one outdoor condenser near the street feeding two or three wall heads spread across different levels of the house, no need to cut duct chases through finished walls on a home like that.
Belmont sits back far enough from the coast that the fog usually clears by early afternoon, so cooling stays moderate most summers. Heating carries more of the load, especially up in the hills where the fog sits longer and the homes run cooler than the flats. On those hillside jobs the line set between outdoor unit and indoor heads runs long, sometimes two stories and well off to the side, and I size the refrigerant charge for that actual run rather than a chart number.

Mitsubishi work we do in Belmont
Flare leaks on long hillside line sets. On the multi-zone jobs above Hallmark Drive, the outdoor unit sits near the street while heads serve rooms two stories up. More line length means more flare joints from the original install, and any one of them can slowly weep refrigerant over a season. We pressure test with nitrogen, remake the leaking joint to torque, then evacuate and weigh in a fresh charge.
Branch box faults on multi-head systems. When one indoor head in a Belmont multi-zone quits while the rest of the house runs fine, the cause is usually the branch box or a loose zone connection, not the outdoor unit. We check the specific zone first instead of tearing into the whole system.
Condensate pump failures on wall heads in converted rooms. Bonus rooms and converted garages in the flat tract neighborhoods often mount a wall head with no gravity path to a drain, so it runs on a small condensate pump. Those clog or burn out and the head drips onto the wall below. We replace the pump and check the line's slope so it doesn't come back.
