Retrofit Air Conditioning For London Apartments: Behind The Scenes

This week, our Managing Director, Savva, is showcasing a Cool You wall-mounted retrofit air conditioning unit we recently installed in a stunning, newly built London apartment. 

You can watch Savva and see our fully internal air conditioning system in the video below:

Here’s how our wall mounted retrofit air conditioning works:

Positioned centrally above utility cupboard doors in the open plan kitchen/living area, the wall unit is blowing out air. During the site survey, a single system was specified to neutralise the heat and cool the entire apartment.

The pipework did not go into the ceiling. Accordingly, we didn’t have to do any remedial work for the apartment. Our team quickly installed our fully internal air conditioning system in one day.

The condenser is directly behind the room unit in the utility cupboard, out of the way. However, in this apartment, the utility cupboard was relatively small. It housed the washing machine, incoming services and storage boxes. Due to a lack of space and to avoid access problems in the future, we suspended the condenser on a specially-made cradle from stainless steel rods.

This retrofit installation is typical of many new or recently built apartments we survey and install our air conditioning system throughout London. Below, we explain more about Cool You and our market-leading fully internal air conditioning solutions.

Why Our Retrofit Wall-Mounted Systems Are Different

• No external unit required – Our water-cooled condenser is installed entirely inside your property, so you can have air conditioning even in apartments where outdoor units are not allowed.
• Perfect for London apartments – Whether you’re in a high-rise, new-build, or a listed conversion, our systems work where traditional ones can’t.
• Discreet wall-mounted design – Units are slim, modern, and blend seamlessly into your interior.
• Cooling and heating in one – Stay cool in summer and warm in winter with efficient inverter technology – zero rated for VAT water cooled heat pump systems.
• Fast and clean installation – Our expert team fits most systems in just a day or two with minimal disruption.

Air Conditioning Without Compromise

When you retrofit a traditional wall-mounted system, you run into challenges:

• External unit restrictions.
• Planning permission in conservation areas
• Visual and noise impact.

Cool You’s retrofit air con solutions avoid all of that. Because our systems are fully internal and use a water-cooled condenser, there’s no need to cut into the building fabric or alter the exterior of your home.

That’s why we’re the go-to choice for London homeowners who thought air conditioning wasn’t possible.

Is a Wall-Mounted Air Conditioning System Right for You?

Our wall-mounted systems are ideal if you:

• Want straightforward retrofit air conditioning with no external unit.
• Need a cost-effective solution for one or two key rooms, such as a bedroom or living area.
• Prefer a modern, compact design that delivers powerful yet economical and environmentally friendly cooling.

For larger apartments or whole-home solutions, we also offer ducted and multi-room internal systems.
