Air conditioning installation · Homes in Plymouth, Exeter & Cornwall
Wall-mounted split systems for bedrooms, home offices and living rooms. They cool in summer, heat efficiently in winter, and cost less to run than most people expect. Installed by our F-Gas registered engineers.
The facts
Power draw. A typical 3.5 kW single-room unit at a SEER rating of 6 to 7 draws around 0.5 to 0.6 kW while cooling. At 26p per kWh that is about 15p an hour. SEER is the seasonal efficiency figure on the unit's label: higher means cheaper to run.
Manufacturer data · OfgemHeating too. In winter the same unit runs in reverse, usually giving 3 to 4 units of heat per unit of electricity. That is far cheaper than any plug-in electric heater.
Manufacturer SCOP dataSummers are warmer. The UK's ten warmest years on record have all been since 2003, and 40°C was recorded for the first time in 2022.

Assumes a 3.5 kW unit per room running at its rated SEER. Multi-room systems sharing one outdoor unit are usually cheaper per room than this.

Options
One wall unit, one outdoor unit, supplied and fitted. No VAT to add. Bedroom, office or living room.
Two to five indoor units off one outdoor unit. Less kit outside, priced per home after a quick survey.
Ducted or multi-split depending on the house. Designed from a survey.
Frequently asked questions
Yes. The same unit runs in reverse in winter and works as an air-to-air heat pump, giving around 3 to 4 units of heat for every unit of electricity. It is a much cheaper way to heat a room than a plug-in electric heater.
A typical single-room unit draws around half a kilowatt while cooling, which is roughly 15p an hour at current electricity prices. The calculator on this page lets you put in your own hours and price.
Usually not for a single outdoor unit on a house, but there are conditions on where it goes and how big it is, and flats, listed buildings and conservation areas are different. We check before we quote.
Anyone handling refrigerant has to hold F-Gas certification. Our registration is FGASS3031823. An uncertified install can void the warranty and is illegal.
Clean the indoor filters every few weeks in summer (it takes a minute) and have the system checked annually. We will show you the filters at handover.
