Stay cool in summer and warm in winter – all year-round comfort made simple
A comfortable indoor temperature can make a huge difference to your home life. Whether you're working from home, relaxing with family, or getting a good night's sleep, our air conditioning systems help keep your space just the way you like it.
At DES Renewables, we supply and install standard wall-mounted air conditioning systems from trusted manufacturers like Mitsubishi Electric and Midea – combining high performance, quiet operation, and energy efficiency. These systems are ideal for homes, home offices, bedrooms, and living spaces. We also install commercial units for offices, retail units, and hospitality settings.
Wall-mounted Units
Wall-mounted air conditioning units are a popular choice for domestic and light commercial settings. Ideal for bedrooms, lounges, offices, garden rooms, or home extensions, these systems are mounted high on the wall to deliver even airflow throughout the space. They are compact, energy-efficient, and operate quietly, making them perfect for maintaining a comfortable temperature without disrupting your daily routine. Connected to an outdoor condenser, wall-mounted units are quick to install and easy to maintain.
Ceiling Cassettes & Floor Units
Every property has unique interior design requirements, and the appearance of room outlets is as important as their functionality. Plaster flush linear slots, measuring 175 mm by 25 mm, can be combined to create custom lengths and incorporate both active and non-active slots. Finished in white with a subtle grey interior, they blend seamlessly with surrounding walls, meeting designers’ needs for a nearly invisible appearance.
Multi-Split systems
Multi-split air conditioning systems are perfect for properties requiring temperature control in multiple rooms. These setups use a single outdoor condenser unit connected to several indoor units, allowing each room to be cooled or heated independently. This zonal control improves energy efficiency and enhances comfort by letting you customise the temperature in each space. Multi-split systems are a smart choice for homes, apartments, and small commercial buildings, offering performance, flexibility, and minimal outdoor visual impact.
