Air Conditioners | Portable, Split & Cassette Systems for Home & Commercial

About

Effective air conditioning is no longer a luxury — as UK summers become hotter and buildings become better insulated, the ability to actively cool and control indoor temperature has become a practical necessity for homes, offices, and commercial spaces alike. This collection covers the full range of air conditioning products, from compact portable units requiring no installation to permanently fitted split systems and ceiling cassettes sized for light commercial applications. Types of air conditioning in this collection Air conditioning products broadly divide by installation type and application, each suited to different building types, room sizes, and usage patterns: Portable air conditioners are self-contained, freestanding units that require no permanent installation. A flexible exhaust hose vents hot air through a window or purpose-made wall sleeve — no refrigerant pipework, no engineer, no planning considerations. Portable units are well suited to rooms where a split system is impractical, temporary cooling requirements, caravans and mobile spaces, and situations where tenant or planning restrictions prevent permanent installation. Performance is rated in BTUs; typical UK rooms of 15–25 m² suit units in the 9,000–12,000 BTU range, while larger or south-facing rooms with heavier solar gain benefit from 14,000–18,000 BTU models. Look for units with integrated dehumidifier and fan modes for year-round utility, and Wi-Fi control for convenience. Wall-mounted split systems consist of an indoor wall unit connected by refrigerant pipework to an outdoor condensing unit. Installation requires a qualified F-Gas registered engineer to handle the refrigerant circuit, but the result is a permanently fitted, highly efficient system with far better performance than any portable unit. Modern split systems use inverter-driven compressors that modulate output to match demand rather than cycling on and off, delivering precise temperature control and significantly lower running c
