Mitsubishi in Berkeley

Mitsubishi heating and cooling in Berkeley.

Berkeley is old housing. Brown-shingle and Craftsman homes in the hills, 1920s stucco in the flats, and a lot of them never had central ducts. Mitsubishi M-Series heads are a common fix here because they add heat and cooling to a wall furnace house without a duct retrofit. We service those installs.

The climate is bay-cool, so the heads mostly run for heat and shoulder-season comfort, not heavy cooling. In the damp we see units ice up or drip, and on the older walls the condensate routing is often the weak point of the original install.

We completed Mitsubishi factory training and read the fault code first. On Berkeley's wall-furnace conversions I check whether the problem is the unit or the way it was mounted before quoting a part.

Common repairs we do

What we close on the truck.

  • Head icing up in cool, damp weather. Berkeley's marine air can push a low-load head into icing. We check the room thermistor, the coil sensor, and the charge. Often it is a sensor reading wrong or a low charge, not a failed compressor.
  • Wall furnace replaced by ductless, now one head weak. Many flats swapped a wall furnace for a couple of M-Series heads. When the far head runs weak, we look at line length charge correction and the branch wiring, because these retrofits often have long runs through old framing.
  • Condensate drip onto plaster. Old lath and plaster makes drain slope hard to get right. A drip or float-switch shutdown usually means a clogged or flat drain line. We clear it, re-slope it, and verify the float.

FAQ

Mitsubishi in Berkeley questions, answered.

  • How far is Berkeley from your San Ramon base?
    We are in San Ramon and reach Berkeley through Oakland, with Piedmont and Orinda also on our Inner East Bay routes. We batch those calls together, so the drive does not add a separate charge.
  • My old house has no ducts. Can Mitsubishi heat it?
    Yes. That is exactly why ductless is popular in Berkeley. We size M-Series heads per room and use a Hyper-Heat outdoor unit so the house holds heat in winter without cutting ducts into your shingle or plaster walls.
  • My head freezes over in the fog. Is the compressor shot?
    Usually not. In cool damp air, icing is more often a sensor reading wrong or a low refrigerant charge. We check those first, and the $75 diagnostic is waived if you move ahead with the repair.
