The UK's most popular air conditioning unit — mounted high on the wall, quiet on low fan settings, and usually installed in a day. We supply and install wall-mounted air conditioning units for homes and businesses across Leicester with a free survey and fixed written quote.
A wall-mounted air conditioning unit — sometimes called a high-wall split or wall-hung unit — sits near the top of the wall and blows conditioned air horizontally across the room at ceiling height, where it falls gently as it cools. The unit's slim profile and white finish make it unobtrusive in most rooms, and the louvre angle is adjustable to direct airflow exactly where it is needed.
Modern wall-mounted units use R32 refrigerant and inverter-driven compressors to achieve energy efficiency ratings that were unimaginable a decade ago — delivering several times more cooling capacity than the electrical power they consume, depending on model and conditions. In heating mode the same technology can provide efficient warmth through winter, with running costs depending on the model, tariff, room heat loss and how the system is used. Most premium models include Wi-Fi connectivity as standard, allowing scheduling and control from a smartphone app.
Most wall-mounted installations across Leicester are completed in a single day — indoor unit fitted, outdoor condenser mounted externally, pipework connected and the system fully commissioned before we leave.
We assess your room, confirm the wall position and outdoor unit location, and provide a fixed written quote. No obligation — prompt survey responses across Leicester.

Premium models can run very quietly on their lowest fan setting. Noise levels vary by model and fan speed.
Inverter compressors can deliver several times more heating or cooling capacity than the electricity they use, depending on the system and conditions.
Switch to heating mode and run all year — often more efficient than direct electric heating, depending on the model, tariff and room conditions.
Control temperature, mode and schedule from your smartphone — at home or away.
Built-in filters can help capture airborne dust and particles as air circulates through the unit. Filtration capability varies by model.
Filter access panel on the front makes cleaning straightforward. Annual service from our engineers maintains peak performance.
Wall-mounted air conditioning is suitable for almost any room in a home or commercial premises.
Cool the main living space in summer and heat it efficiently in winter from a single unit.
Low-noise operation and sleep mode for restful bedrooms.
Maintain the right working temperature year-round without disrupting video calls.
Cool or heat the dining space independently for comfort during mealtimes.
Individual office climate control — each room at its own temperature.
Quiet, controllable climate for focused meetings and client visits.
Cost-effective cooling for small to medium retail spaces.
Year-round outbuilding comfort — heating and cooling from one unit.
From free survey to fully commissioned system — typically in one visit.
We measure the room, confirm the wall and outdoor unit position, and check the pipe run route.
Fixed written quote with the agreed scope clearly set out before work starts.
Indoor unit, outdoor unit and pipework installed, with refrigerant work undertaken by appropriately F-Gas certified engineers.
System commissioned in both modes, demonstrated and handed over with full documentation.
Wall-mounted units are typically installed approximately 200–300mm below the ceiling — high enough for effective air distribution but accessible for filter cleaning without a ladder. The exact position is confirmed during the survey based on the wall construction, window positions and pipe run route.
Modern premium units can run very quietly at minimum speed. Indoor and outdoor noise levels vary by model, capacity, installation position and fan speed, so we confirm expected sound levels during specification.
Unit size depends on the room dimensions, glazing area, insulation and the number of heat sources. As a rough guide, a 2.5kW unit suits rooms up to around 20m², a 3.5kW unit suits up to 30m², and a 5kW unit suits up to 45m². We calculate the precise requirement during the free survey.
Most units are white as standard. Some manufacturers offer alternative colours or finishes — Daikin, for example, offers certain models in silver or black. We can confirm colour options available for the model you choose during the survey.
