Mitsubishi in Martinez

Mitsubishi heating and cooling in Martinez.

Martinez has a stock of older downtown homes, many Victorian and early-century, plus mid-century neighborhoods spreading south and east. A lot of the older homes have wall furnaces and no ducts, so Mitsubishi M-Series heads get added for heating and cooling. We service those and MXZ multi-zone across town.

This is Diablo Valley along the strait, so summers run warm inland from the water and winters stay mild. The older homes near the waterfront also see some salt and industrial air that is rough on outdoor coils. So we get heat, comfort, and coil-condition calls about equally.

We completed Mitsubishi factory training and read the fault code first. On a wall-furnace conversion in an old home the condensate and line routing often explain the symptom, so I check the install before pricing a part.

Common repairs we do

What we close on the truck.

  • Wall-furnace conversion head running weak. Old Martinez homes that swapped a wall furnace for ductless often have long line runs through old framing. A weak head is usually a charge issue on that run or a dirty coil. We measure and clean before condemning the unit.
  • Outdoor coil corrosion near the waterfront. Salt and industrial air age the condenser coil and fan. A unit losing capacity often has corroded fins and a tired fan motor. We treat or comb the coil and replace the fan motor when the amp draw is high.
  • Condensate drip onto old plaster. Old lath and plaster makes drain slope hard to get right. A drip or float shutdown usually means a clogged or flat drain line. We clear it, re-slope it, and verify the float switch.

FAQ

Mitsubishi in Martinez questions, answered.

  • How far is Martinez from your San Ramon base?
    We are in San Ramon and reach Martinez through Walnut Creek and Pleasant Hill, with Concord next door, all on our Diablo Valley routes. We batch those calls, so the drive does not add a fee.
  • My old house has a wall furnace and no ducts. Is Mitsubishi a fit?
    Yes. Ductless is the clean replacement for a wall furnace. We size M-Series heads for your rooms and run a heat pump outdoor unit so you get heating and cooling without cutting in ducts.
  • My outdoor unit looks corroded and cools weak. Can it be saved?
    Often yes. Near the water the coil fins corrode and the fan tires, which drops capacity. We treat the coil and replace the fan motor when needed, and only recommend the outdoor unit if the coil is leaking.
