Close to downtown and Laurel Street, San Carlos has a mix of older bungalows with tight crawl spaces and residential units built above ground-floor shops. Neither has a real path for ductwork, the bungalows because the crawl space was never sized for it and the upper units because there's a commercial space in the way below. A Mitsubishi mini-split, single head for a small unit or a two-head system for a full bungalow, gets heating and cooling into those spaces without opening a ceiling or fighting a shop's HVAC layout underneath.
Up in the Highlands, the homes are bigger and newer, and a fair number already run proper forced-air ductwork from a remodel. There, Mitsubishi work is usually a multi-zone add-on, an addition, a bonus room over the garage, or an office the main system never quite kept comfortable, rather than a full duct replacement. San Carlos doesn't run brutally hot most of the year, so I size for a normal Peninsula summer and make sure the system isn't oversized to the point it short-cycles on the mild days that make up most of the season.

Mitsubishi work we do in San Carlos
Ductless design for units above Laurel Street storefronts. Residential units sitting over downtown shops have no path to run ductwork through the commercial space below. A single or two-head Mitsubishi system solves heating and cooling for the unit without touching anything on the ground floor. We size the head to the room, not the building.
Weak airflow from a dirty blower wheel and coil. The most common service call on downtown bungalow wall heads is weak airflow or a musty smell, almost always a blower wheel and coil that haven't been cleaned since install. We pull the head apart, clean both, and check the drain slope while it's open.
Branch box zone faults in Highlands additions. Larger Highlands homes running a Mitsubishi multi-zone for an addition or office see the occasional zone drop out while the rest of the house is fine. That's usually the branch box or a loose zone wire, not the compressor, and we diagnose the specific zone before replacing anything.
