Commercial buildings in Los Angeles are almost always served by one of three system categories. Single-split systems pair one outdoor condenser with one indoor air handler and work well for small offices, retail suites, and server rooms that need independent control. Multi-split systems connect several indoor units to a single outdoor unit, which saves roof and ground space in mid-sized buildings with a handful of zones. VRF (variable refrigerant flow) and VAV rooftop package units are the workhorses of larger commercial properties, they modulate refrigerant or airflow across many zones, deliver heating and cooling simultaneously, and integrate with building automation systems.
The right choice depends on square footage, zoning needs, occupancy patterns, and ceiling or roof access. Our team sizes the system using a Manual N load calculation so the equipment matches the building instead of the guesswork.
