Why buy from the specialist
Air conditioning is all we do. That focus is the difference between surviving a heatwave and sweating through it.
Free, fast & honest delivery
Free UK delivery on every in-stock item — most in 2–4 working days, with the exact ETA shown on each product. No vague promises, no nasty surprises at checkout.
Sized right, not oversold
Our free sizing tool matches BTU to your room. No guessing, no returns, no unit that can't keep up.
Eco R290, lower bills
Every portable we sell runs ultra-low-GWP R290 refrigerant — GB compliant, kinder to the planet and your meter.
Real UK aftercare
Warranty, spares and human help based in the UK. Buy from a specialist, not a faceless marketplace.
Beat the rush
Shop in-stock unitsWhen the heatwave hits, everywhere sells out.
We hold stock all summer so you don't spend July refreshing “out of stock” pages. Get sorted before it's 35°C in the bedroom.
Questions, answered
Everything you need to know before you cool down.
No. Our portable units are plug-and-play — wheel it in, pop the window kit in, and switch on. Even our plug & play split systems are pre-charged and designed for DIY install with no F-gas engineer required.
