Gree in San Mateo
We repair and service existing Gree mini-splits. For new ductless installations in San Mateo, we install Mitsubishi Electric.
San Mateo runs from the older craftsman bungalows near downtown, plenty of them with an apartment or a converted room tucked above a storefront on the restaurant-heavy blocks of B Street, up to the bigger homes spread through Baywood and the Highlands in the hills. Downtown, the ceiling space over a shop almost never has room for ductwork, so a single ductless head becomes the practical way to add real heating and cooling instead of leaving a space with just a window unit or nothing at all.
Up in the hills, it's a different job, usually a bonus room, a converted garage, or an addition that the main system's ductwork was never extended to reach. A ductless zone handles that room on its own, and the one we install is Mitsubishi Electric. On a full hillside estate going all-ductless across several zones, the same Mitsubishi Electric line applies, since the parts support and the multi-zone lineup are built for that scale of job.
We're part of the ADRIUM Service Solutions family, CSLB #1136642, EPA Section 608 Universal certified for refrigerant handling. The $99 diagnostic is credited toward the repair, you get a written estimate before we start, and we're out here seven days a week. Call (925) 999-4095.
Gree work we do in San Mateo
Ductless retrofits above downtown storefronts. A unit or a converted room above a shop near B Street has no attic and no crawl space to run duct through. A ductless head solves that with one line set through an exterior wall, giving the space real heating and cooling instead of relying on a window unit or a space heater.
Bonus rooms and additions in the Baywood and Highlands hills. These hillside homes often have a room over the garage or a finished basement that the main ducted system was never extended to serve. We size a single ductless zone to that room's actual load and keep it separate from the rest of the house's system, so it doesn't strain the existing equipment.
Erratic cycling from a failed sensor. When a Gree indoor unit short-cycles or won't hold a set temperature, the thermistor sensor reading room or coil temperature is usually the first thing I check, not the compressor. It's a small part, but it has to be the right one, and we confirm availability before we schedule the repair.
