Split system
T3 inverter, R32, reverse cycle. Supplied, installed and serviced by us, with parts held locally.
The larger T3 inverter system, for big living rooms, meeting rooms, shops and open-plan spaces — roughly up to 30 m². Same platform as the AC14K, more capacity.
Sized for rooms a 12,000 BTU unit cannot hold: large living rooms, retail floors, clinics and open offices where one indoor unit has to reach the far corner of the room.
It shares the AC14K platform — the same T3 rating, the same R32 charge, the same inverter control approach — so a technician who knows one knows the other, and the service parts overlap. What changes is the condenser and the capacity.
Heating output is 20,000 BTU/h. In a commercial space that runs through winter as well as summer, a reverse-cycle system usually pays for itself against separate heating equipment.
