A split system has two halves joined by copper pipes, a cable and a drain hose. The indoor unit on the wall blows cool air, and the outdoor unit holds the compressor and a large fan. In Soviet-era blocks the outdoor half usually sits on a bracket under a window or on the balcony rail, sometimes eight or ten floors above the street. In new-build towers developers often provide a technical niche or a spot on the balcony, although many white frame and black frame flats are handed over with no air conditioning at all.
Inverter and older on/off units
Newer models are mostly inverter units that vary the compressor speed, which keeps the room temperature steady and uses less electricity. Older on/off units run the compressor at full power and then stop it completely. Both types can be repaired, but for a very old unit the technician may tell you frankly that the repair would cost close to a replacement.
Heating mode in winter
Plenty of tenants use their split unit as a heat pump from November to March, especially in flats without radiators. A unit that cools well but heats poorly, or the other way round, points to a different group of faults, so say which mode gives trouble. If your main heating is a radiator system, our heating page (in Georgian) covers that work.
- Multi-split systems, where one outdoor unit feeds two to five indoor units, are common in larger flats and houses.
- Floor-standing, ceiling and cassette units appear in shops, cafes and offices.
- Portable units with a hose through the window have fewer serviceable parts, and the technician will say whether a repair makes sense.
