It has two parts: a slim indoor unit mounted high on the wall, and a compact outdoor unit outside. The two are joined by insulated refrigerant pipes and a cable through a small hole in the wall. Split systems are ideal for a single room: a bedroom, living room, home office, conservatory, loft conversion, small shop or treatment room. They cool in summer and, working as a heat pump, provide efficient heating in cooler months. People usually choose a split system when one particular room overheats, when they want quieter, more efficient cooling than a portable unit, or when a small business needs reliable comfort for staff and customers. Professional installation matters because the refrigerant connections must be joined and leak-tested properly. We are F-Gas and REFCOM registered and an accredited installer for Panasonic, Samsung, LG and Mitsubishi. ### Who we work with - Homes - Offices - Shops - Bars - Restaurants - Gyms - Medical premises - Industrial unitsAccredited installer for Panasonic, Samsung, LG and Mitsubishi. Why It Matters ## The cost of getting a split system wrong The wrong unit size is the biggest risk. An undersized unit runs constantly and never quite cools the room. An oversized unit short-cycles, leaves the air damp and wastes energy. Poor positioning causes daily discomfort: a unit that blows straight onto your bed or desk, an outdoor unit that disturbs neighbours, or a drain that runs down the wall. Living with an overheating room also has a cost. Poor sleep, lost productivity and portable fans or coolers that use more power for less result. ### Common mistakes to avoid - Picking a unit size without a survey - Buying a DIY or 'pre-charged' kit and hoping for the best - Placing the outdoor unit in full sun or a tight corner with no airflow - Forgetting about condensate drainage - Not planning a yearly service Our Process ## How it works, step by step - 1 ### Free survey We measure the room, check sun exposure and insulation, and agree where the indoor and outdoor units should go. - 2 ### Quotation You get a free written quote based on the unit size (kW) and the materials needed. - 3 ### Installation We mount both units, drill a single neat hole, run insulated pipework and connect power and drainage. - 4 ### Testing We check the pipes for leaks, then switch the system on and make sure it works properly. - 5 ### Handover We show you the controls and explain your 3-year parts warranty and 1-year workmanship guarantee.

In Detail ## Split system sizes, prices and options Split systems come in different capacities and styles. Here is how to understand the options. ### 2.5kW split system: from £1,300 Typically suits a standard bedroom, small home office or small treatment room. ### 3.5kW split system: from £1,500 Typically suits a larger bedroom, living room or small open-plan area. ### 5kW split system: from £1,800 Typically suits a large lounge, open-plan kitchen-diner, conservatory or small commercial space. Prices depend on unit size and materials, and VAT is included on domestic jobs. ### What affects the size you need Room size is only the start. South-facing glass, poor insulation, high ceilings, computers and people in the room all add heat. That is why every quote follows a free survey. ### Adding more rooms later If you'd like more than one room covered, a multi-split system can run several indoor units from one outdoor unit. Deals are available on multiple units. ### Homes and small businesses In homes, we prioritise quiet running and discreet placement. In shops, offices and treatment rooms, we plan around opening hours and customer areas.
