Mestic Air Conditioning Units: The Complete Range Guide
Mestic is one of the most established names in caravan and motorhome air conditioning across Europe. Whether you need a compact rooftop unit for occasional summer cooling or a powerful split system for full-time touring in hot climates, there is a Mestic air conditioning unit designed for the job. This guide walks through the complete range so you can find the right match for your vehicle and your needs.
Rooftop Air Conditioners
Rooftop units are the most popular type of caravan air conditioner. They mount in a standard 400mm x 400mm roof opening — the same cutout used by most roof vents — and distribute cool air downward into the living space. Installation is straightforward and keeps floor space completely clear.
The Mestic rooftop range spans several power levels. The RTA-1700L is the entry point at 1700W cooling, suitable for smaller caravans and campervans. The RTA-2600 steps up to 2600W for larger vehicles or hotter conditions, while the RTA-3600i is the flagship with inverter technology for maximum efficiency and whisper-quiet operation.
All rooftop models include heating mode for shoulder-season use, so you get year-round climate control from a single unit.
Split Unit Air Conditioners
Split units separate the compressor (mounted externally or in a garage compartment) from the internal air distribution unit. This gives several advantages: lower noise inside the vehicle, no roof modification needed, and the ability to position the cooling output exactly where you want it.
The Mestic SPA-3000 and SPA-3100 cover mid-range cooling needs, while the SPA-5100 at 1471W delivers serious cooling for larger motorhomes and touring vehicles. The SPA-5100 features touchscreen control, night mode for quiet overnight operation, and eco-friendly R290 refrigerant.
Split units are particularly popular with motorhome owners who prefer not to cut into the roof or who want the lowest possible interior noise levels.
Which Type Suits Your Vehicle?
For caravans with a standard roof vent opening, a rooftop unit is usually the simplest choice. Installation is a weekend job for a competent DIYer, and the result is clean and unobtrusive. For motorhomes with garage compartments or owners who want the quietest possible operation, a split unit is worth the slightly more involved installation.
Consider the size of your vehicle when choosing power output. As a general guide: vehicles under 6 metres suit 1700 to 2000W, 6 to 8 metres suit 2500 to 3000W, and vehicles over 8 metres or those used in consistently hot climates benefit from 3600W or the SPA-5100.
Power Requirements
All Mestic air conditioning units run from 230V mains power, which means campsite hook-up or a suitably sized inverter and battery bank. Soft-start technology is included on most models, reducing the initial surge current so the unit works reliably on standard UK campsite bollards rated at 10 or 16 amps.
Running an air conditioner from battery power is possible but demands a substantial setup — typically 400Ah or more of lithium battery capacity combined with strong solar input. For most owners, campsite hook-up is the practical power source for air conditioning.
