R32 — fixed-install unit

Refrigerant details from the manufacturer — ask us if unsure.

This Costway portable air conditioner offers 9000 or 12000 BTU of cooling in one unit and uses R32 refrigerant for efficient performance. At its 12000 BTU rating it suits rooms of around 20 m² – a lounge, large bedroom or open-plan study – following the ~600 BTU per m² rule. Power draw is 920-1099W depending on mode, so running cost lands around 24-29p per hour at 26p/kWh. The 3-in-1 design covers cooling, drying (dehumidify) and ventilating (fan) with three wind speeds, and a 24-hour timer with quiet operation looks after sleep. A useful extra is the pair of filtration screens that help clean the air as it cools. As a single-hose monobloc it vents through a window via the included kit; there is no hoseless cooling, so the exhaust hose is essential. Cool mode spans 16-31°C, controlled from the panel or remote. The box includes the exhaust hose, hose connector, drainage hose, window kit, window kit adapter, remote and manual. At 27 kg on wheels it still moves easily between rooms, a capable air conditioning unit for larger UK living spaces.

9000/12000 BTU Portable Air Conditioner with Remote Control — FAQs

What is the difference between the 9000 and 12000 BTU settings?

9000 BTU suits smaller rooms of around 15 m², while the 12000 BTU rating handles up to about 20 m². Choose the higher setting for larger lounges or faster cooling.

What refrigerant does it use?

It uses R32, a widely adopted refrigerant valued for efficient heat transfer and a lower environmental impact than older gases.

Does the Costway 9000/12000 BTU unit need venting?

Yes. It is a single-hose portable air conditioner and must vent warm air outside through the included exhaust hose and window kit.

How much does it cost to run per hour?

It draws 920-1099W depending on mode, so at 26p/kWh expect roughly 24-29p per hour.

Does it help clean the air?

Yes. Two filtration screens trap dust and particles as air passes through, helping keep the cooled air cleaner.
