The Smart Solution for London Homes
Living in London often comes with restrictions. If you're in a flat, listed building, or conservation area, installing a traditional air conditioning system can be impossible due to bans or restrictions on external condensers (air con boxes). That’s where Cool You steps in. Our internal home air conditioning units are fully self-contained, making them ideal for properties where outside units aren’t allowed.
We're really proud of our residential air conditioning service and systems. But don't take our word for it - have a look at some of our recent reviews.
Why Choose an Internal Home Air Conditioning Unit?
Designed for London Living
Whether you live in a high-rise apartment or a Georgian or Victorian-listed townhouse, our systems work seamlessly inside your home. No planning permission, no disruption, and no compromise on comfort.
Cool You systems are tailored specifically for the demands of Central London living.
We've successfully installed fully internal air conditioning in some of the capital’s most prestigious and challenging residential areas, including: Kensington & Chelsea, Mayfair, Marylebone, Southbank & SE1, Canary Wharf, Hampstead, Islington, Battersea and Vauxhall, amongst many other areas of Central and Greater London.
Simply enter your postcode in the search bar on our Case Studies Page, and you'll find a property in your area that we've successfully air conditioned.
Our bespoke water-cooled systems are the perfect fit for:
- Georgian and Victorian townhouses or mansion blocks
- Mews houses and architect-renovated heritage homes
- Contemporary modern apartment buildings
- Landmark brutalist properties like those in The Barbican Estate
No matter your architecture or postcode, we have a system designed for you. Our systems work seamlessly inside your home. No planning permission, no disruption, and no compromise on comfort.
Space-Saving and Quiet
Our water-cooled systems fit neatly inside utility cupboards or kitchen cabinets. The indoor ac units are whisper-quiet and blend perfectly with your interior, ensuring you stay cool without even noticing they're there.
Efficient and Reliable Performance
Each system uses a 3000-stage water control valve for highly responsive cooling. It intelligently adjusts to maintain your desired temperature efficiently – far superior to standard open/close valve systems found elsewhere.

Cool You – Unmatched Expertise in London Homes
Built for London, Not Just Installed in It
Our fully internal home air conditioning units are designed around the demands of urban living in London:
- Solar gain: Large glass areas, skylights, and exposed south-facing walls can trap intense heat. Our systems counter this with rapid response cooling technology and superior humidity control.
- Limited space: Compact internal components are designed to fit discreetly in cupboards or service areas – perfect for London’s space-tight flats.
- Noise sensitivity: From mansion blocks to riverside apartments, peace matters. Our systems run quietly and efficiently, with whisper-quiet ac internal units that won’t disturb your home or your neighbours.
Exclusive Internal Systems Only from Cool You
Unlike generic solutions, our systems are exclusively developed by Cool You for the London market. They’re not repurposed commercial units or off-the-shelf models – every element is custom-specified to ensure performance, efficiency, and reliability. We don’t compromise, and neither should you.
Advanced Efficiency & Modern Refrigerants
Our latest systems use cutting-edge refrigerants such as R32, known for their high efficiency and lower environmental impact. Combined with a 3000-stage water flow control valve, they maintain optimal cooling performance while conserving water and energy – far more sophisticated than the basic open/close valves many systems still rely on.
