Not Just Air Conditioning. Heating Too.
Most modern split systems are reversible air-to-air heat pumps. The same quiet indoor unit that cools a stuffy bedroom in July can provide efficient warmth on a cold January evening.
How well a system performs depends on the room, insulation, the unit chosen and outdoor conditions — which is why every recommendation starts with a survey.
Find the Right System for Your HomeSummer
Cool, dehumidified air for sleep and focus.
Winter
Responsive heat with precise control.

Garden rooms & home offices
Make your garden office usable in every season
Garden rooms often overheat in summer and feel cold in winter. A properly sized split system can provide both heating and cooling without running wet central heating to the bottom of the garden.

FAQs
Common questions
Can air conditioning really heat my home as well?
Most modern split systems are reversible air-to-air heat pumps, so the same unit can cool in summer and heat in winter. How well a system heats depends on the model, the room and the outdoor temperature, which is why we assess every space before recommending anything.
How long does an installation take?
It depends on the property, the number of rooms and the route for pipework and cabling. We'll give you a realistic timescale after the survey rather than guessing beforehand.
What does it cost to run?
Running costs depend on the size of the room, insulation, how you use the system, the unit's efficiency and your electricity tariff. We can talk you through the factors involved, but we won't promise specific savings without understanding your property.
Where does the outdoor unit go?
The outdoor unit is usually mounted on a wall bracket or a ground stand close to the indoor unit. We'll discuss positioning, appearance, noise and access with you during the survey.
