LG in Atherton
We repair and service existing LG mini-splits. For new ductless installations in Atherton, we install Mitsubishi Electric.
Atherton is large-lot estate housing, and the main HVAC here is multi-zone ducted, frequently two or three independent systems per house. That is not LG's core strength, and we say so. Where ductless earns a place on a Peninsula estate is the spaces that sit outside the main ducted footprint: a detached studio, a guest house, a wine room, or a primary suite that the central system never quite balances. A ductless multi-zone mini-split conditions those without extending ductwork across a sprawling floor plan.
The Peninsula climate makes a heat pump the efficient year-round answer here. Summers stay mild and winters rarely approach freezing, so an inverter heat pump covers both heating and cooling on the spaces it serves. The app control also suits the way these homes are run, where a guest house or studio only needs conditioning when it is in use.
The tradeoff to know with LG is that it is electronics-forward. Diagnostics lean on reading boards and communication faults rather than swapping a single mechanical part. On the LG multi-zone systems we service here, that means we trace the actual fault, which head or sensor or board, instead of replacing the easy thing and hoping. That is the same diagnostic discipline we bring to the ducted estate systems.
LG work we do in Atherton
Ductless for guest houses, studios, and detached spaces. We install Mitsubishi Electric multi-zone mini-splits to condition buildings the main ducted system does not reach, like a detached guest house or studio. One outdoor unit serves several indoor heads, which avoids running new ductwork across a large parcel.
Spot-zoning rooms the central system fights. On big floor plans, one room often runs hot or cold no matter how the ducted zone is balanced. We add a ductless head to that room as a dedicated zone so it stops fighting the main system.
Heat pump conversions on auxiliary buildings. Older ranch-estate outbuildings often still run a small gas furnace or nothing at all. We convert those to a Mitsubishi Electric ductless heat pump head, adding heating and cooling; supported existing LG units have app control the owner can run only when the space is occupied.
Board and communication-fault diagnostics. LG faults usually show as a communication error between the indoor and outdoor units rather than a clean mechanical failure. We read the codes, check sensors and wiring, and isolate the real cause before quoting a board.

Why use ductless only on the secondary spaces and not the main system?
