Split Unit Air Conditioners

Mestic split unit air conditioners separate the compressor from the indoor unit for quieter, more flexible installation in caravans and motorhomes. The compressor mounts externally or in a garage compartment while the indoor unit distributes cool air exactly where you need it, no roof modification required.

Split unit systems are the quietest type of caravan air conditioner because the noisiest component sits outside the living space. This makes them ideal for overnight use, light sleepers, and owners who want air conditioning without compromising on cabin noise levels. Models range from mid-output units for standard tourers to the powerful SPA-5100 with touchscreen control and eco-friendly R290 refrigerant for larger motorhomes.

Every Mestic split air conditioner includes heating and cooling modes, night mode, and remote control. Soft-start technology ensures reliable operation on UK campsite power.
