What air-conditioning systems do hotels in the UK use and how are they chosen?

Hotels in the UK rely on a combination of air-conditioning systems depending on building layout, guest expectations, and energy performance goals. These include ducted central systems, VRF setups, wall-mounted split units, packaged terminal air conditioners, and modern air source heat pumps. Each system has its own use case, from space-saving designs to energy-efficient solutions suited for different room types. The choice is influenced by building regulations, acoustic considerations, installation complexity, and long-term running costs.

Why air-conditioning matters in hotels

In hospitality, guest comfort is closely linked to temperature control, air circulation, and humidity regulation. Systems that allow guests to control their room settings improve satisfaction scores and return visits. In London and other high-demand cities, competitive hotels often install individual controls and noise-optimised units in every room. Local air conditioning contractors like Right Air Solutions play a key role in advising on installation, regulatory compliance, and equipment servicing.

Pro Tip: Schedule preventative maintenance at least twice a year. Regular checks on filters, coils and refrigerant levels keep systems running efficiently and avoid expensive emergency breakdowns during peak seasons.

Central air conditioning systems

Centralised systems use a network of concealed ductwork to deliver air from rooftop or basement plant rooms. These systems are common in hotels with over 50 rooms and allow integration with building management systems (BMS). With features like demand control ventilation, high-efficiency motors, and zoning, central systems support energy goals while keeping mechanical components out of guest spaces. Filters must be replaced regularly to maintain clean air and minimise allergens.

Packaged Terminal Air Conditioners (PTAC)

PTAC units are self-contained systems typically installed under windows or through exterior walls. They are popular in hotels without existing ductwork and allow individual temperature control. Modern PTACs include inverter compressors, allowing quieter and more energy-efficient operation. In the UK, PTAC systems are popular in cost-conscious refurbishments and for quick installation timelines. They are supported by suppliers offering portable air conditioner rental for temporary needs.

Pro Tip: When selecting an air-conditioning unit, look for models with R32 refrigerant. It offers higher efficiency and a lower global warming potential compared to older refrigerants, helping your hotel meet future environmental standards.

Split and multi-split systems

Wall-mounted split systems offer a practical and quiet solution for guest rooms. A single outdoor unit can serve multiple indoor units in a multi-split arrangement, saving on outdoor space. These systems often include high SEER ratings (Seasonal Energy Efficiency Ratio) and come equipped with smart controls for remote management. Right Air Solutions frequently installs these systems in boutique and mid-size hotels across London, Kensington, and Chelsea. Routine servicing is necessary to avoid blocked filters and ensure optimal airflow.

Variable Refrigerant Flow (VRF) systems

VRF systems are scalable and can heat and cool different zones at the same time. These systems adjust refrigerant flow dynamically based on demand. Hotels using VRF technology can offer more stable temperatures and reduce noise through quieter indoor fan coil units. These are ideal for luxury hotels where guest experience is a top priority. VRF systems are also compatible with underfloor heating and mechanical ventilation heat recovery (MVHR) systems, improving sustainability performance.

Air source heat pumps in UK hotels

Air source heat pumps (ASHP) offer an alternative to traditional gas boilers. They absorb heat from the outside air, even in cold weather, and use it for heating and hot water. Hybrid systems combine ASHP with gas backup for peak efficiency. ASHPs are widely used in sustainable hotel builds aiming to reduce carbon emissions and operating costs. UK regulations support ASHP installations under permitted development rules, although noise and placement must meet local authority requirements.

Installing wall mounted air conditioning units on the front elevation of properties in protected areas often requires formal approval. You may also be restricted in your choice of unit depending on its appearance and sound output.

Through the wall and window-mounted systems

These legacy systems are mostly found in older hotels and guest houses. While installation is fast and upfront costs are lower, they lag behind in energy efficiency and noise reduction. Modern equivalents often include integrated dehumidifiers and digital thermostats. These systems are suitable for retrofits where ducted solutions are impractical.

Portable and temporary air conditioning units

In events, conference spaces, or during renovations, hotels often use portable air conditioning units. UK-based suppliers offer short-term rentals with delivery and installation. This option is also popular in listed buildings with installation restrictions. Features to look for include programmable timers, HEPA filtration, and variable fan speeds.

Server room and IT suite cooling

Hotels with on-site server rooms or telephony infrastructure require consistent cooling to prevent equipment failure. These rooms are typically equipped with standalone ducted systems or precision air conditioners with close control features. Local firms offering comms room air conditioning services can also install alerts for temperature thresholds and remote diagnostics.

Energy efficiency measures

All systems require scheduled servicing to prevent breakdowns. This includes coil cleaning, checking refrigerant levels, filter replacement and diagnostics. Commercial air conditioning service contracts ensure system uptime and can include emergency AC repairs and 24-hour support. MVHR servicing is particularly important in air-tight buildings.

Guest expectations and smart room controls

Modern guests expect intuitive climate control. Hotels that integrate air conditioning with their booking and management systems can improve satisfaction. Features like motion detection, energy saving mode and voice-activated assistants (e.g., Alexa, Google Assistant) are becoming standard in new builds and tech-forward renovations.

Indoor air quality and guest health

Many hotels now monitor air quality with PM2.5 sensors and carbon dioxide monitors. High CO2 levels affect concentration and sleep quality. Ventilation upgrades and in-room purifiers help ensure compliance with health and safety standards. Some providers also offer air testing in your home or business, useful for reassurance after renovations or HVAC upgrades.

Signs your hotel AC system needs an upgrade

Frequent guest complaints, high energy costs, or difficulties sourcing parts are signs that your system may be outdated. New installations with features like R32 refrigerant, smart zoning, and modular compressors offer better performance and longevity.

Do UK hotels need planning permission for air conditioning systems?

For listed buildings or those in conservation zones, planning permission may be required. Noise regulations also apply, particularly for external compressors and heat pumps. Right Air Solutions provides planning support and equipment that complies with air source heat pump permitted development rules.

Choosing the Right System for Long-Term Value

Hotel air conditioning in the UK continues to evolve. Whether you manage a luxury hotel, small B&B, or event space, choosing the right air conditioning solution involves balancing efficiency, guest comfort and regulatory compliance. Brands like Mitsubishi, Daikin and Toshiba remain popular, while demand for low-carbon options such as heat pumps is growing. Partnering with a local expert like Right Air Solutions ensures installations meet both technical and guest satisfaction requirements. Need hotel room air conditioning units in London?
