Wall Mounted Air Conditioning Units

Wall mounted air conditioning units are one of our most popular and adaptable solutions for retrofitted cooling in London flats and apartments. Each system combines a sleek wall-mounted room unit with a state-of-the-art, water-cooled internal condenser (the condenser is usually situated in a utility cupboard). This eliminates the need for any external condenser.

The units are designed to operate at whisper-quiet levels and are extremely energy efficient. Sitting high on a wall, these wall units will blend discreetly in your space while keeping you perfectly cool. Being wi-fi enabled, our systems use the leading i-feel system that allows you to control the room temperature from wherever you are in the room.

As part of Cool You’s fully internal water-cooled air conditioning systems, these wall-mounted units are purpose-built for London apartments and listed buildings in London where external condensers are not allowed. They give exceptional performance, rivalling and often surpassing industry-leading conventional systems. This level of performance makes them the ideal choice when installing an outside condenser box isn’t an option.

What is an Internal Water Cooled
Air Conditioning System and How Does it Work?

With most London apartment buildings, you are not permitted to use external condensers or make penetrations through the exterior walls of the building. Our internal water-cooled air conditioning systems are a no-compromise solution for fully-fledged air conditioning where you cannot have an external condenser box.
It's all on the inside... Wall mounted air conditioning

Our entirely internal solution includes a whisper-quiet room unit (fan-coil) -  wall mounted air conditioning unit. This is installed in the room that's going to be air-conditioned. We typically specify a wall-mounted unit for a retrofit installation. Still, it can also be a concealed ducted unit, usually specified during complete home refurbishments. The room units are sleek and neutral, so they will not clash with your colour scheme.

The room unit is the element that gives you complete climate control through air purification, cooling, and dehumidification, providing you with the ideal environment through effortless cooling.

    Wall Mounted Air Conditioning Units - No visible pipework and no ugly condenser outside...

    Our system's installation is designed for your convenience. The refrigeration pipework (using the latest environmentally friendly R32 refrigerant) typically runs from the room unit into the ceiling void, which is concealed to the condenser box. Our innovative approach places the condenser on the inside, hidden from view in your London apartment, unlike traditional systems with unsightly external condensers.

    In most cases, we strategically position the unit in the utility space or under a kitchen counter, ensuring it remains conveniently hidden yet near the required services. The exact location will be discussed during your site survey, providing a tailored approach that perfectly meets your needs.

    Unlike conventional systems, our internal condensers utilise water to dissipate heat in a controlled and highly efficient manner. This pioneering design has allowed us to manufacture a condenser that is a fraction of the size of an external air-cooled box. Our internal condensers are compact, remarkably quiet, and incredibly efficient, a testament to our unwavering commitment to delivering the best product to you, our customer.

    Every Cool You air conditioning system is unique

    We will guide you to an exclusive bespoke solution, meticulously crafted for your property and installed by our in-house team. Others may try to match our systems, but they can't replicate the unique touch we bring to each project. It’s pretty flattering, we must admit!

    Our prices include the entire supply, installation, commissioning, bullet-proof 6-year parts, and labour warranty - covering the room unit, internal condenser, and all refrigeration pipework, subject to a signed maintenance agreement. This means you can relax, knowing your system is protected long after installation. For additional components, such as the condensate pump (where fitted) and plumbing connections at the condenser, we provide a 1-year warranty, offering you clear and comprehensive coverage across every part of your system.

    In many cases, just a single system can eliminate the heat build-up in your apartment - we never over-specify.

    Whether you decide to do one or all rooms, we will provide you with a single appropriately sized condenser that allows you full independent control of each room.

    Every time we up-size the condenser to add an additional unit, the condenser becomes more sophisticated and complex and more than doubles in price, hence why we charge on a per-room basis - This is not a cost-saving exercise; it's a space-saving exercise.
