Sussex Air Conditioning provides commercial air conditioning installation, service, and maintenance for businesses across East Sussex, West Sussex, and the surrounding area. With over 20 years of experience working in commercial environments, we have installed systems in everything from single offices to large multi-zone industrial buildings – and we bring the same level of expertise to every project, regardless of size.
We offer a complete commercial air conditioning service covering the full project lifecycle, from initial survey and system design through to installation, commissioning, and ongoing maintenance.
Our commercial installation service covers everything from single split systems for small offices to full VRF multi-zone systems serving entire buildings. We carry out a free site survey before any work begins, specifying the right system for your building type, occupancy, and budget. All air conditioning installations are carried out by our F-Gas certified engineers and commissioned to manufacturer standards.
Regular servicing protects your investment, maintains energy efficiency, and keeps your system compliant with F-Gas regulations. We offer flexible service and maintenance contracts tailored to commercial requirements, including planned preventative maintenance visits, priority callout cover, and annual compliance certification.
If your commercial air conditioning system has developed a fault, our engineers provide rapid response callout across Sussex. We carry a comprehensive range of spare parts and work with all major manufacturers including Daikin, Mitsubishi Electric, Fujitsu, and Samsung.
For buildings requiring a new system or a full replacement of ageing equipment, we carry out a full load calculation and system design before specifying equipment. We manage redundant system removal, new installation, and commissioning as a single turnkey service.
We supply and install all major types of commercial air conditioning system, advising on the most appropriate solution for your building after a free site survey.
Variable refrigerant flow systems are the preferred choice for larger commercial buildings. A single outdoor unit can serve dozens of indoor units across multiple floors and zones, with simultaneous heating and cooling available in 3-pipe configurations. VRF systems offer exceptional energy efficiency and precise zone control – ideal for office buildings, hotels, and large retail environments.
Ceiling cassette units sit flush within a suspended ceiling and distribute air evenly in four directions. They are widely used in offices, meeting rooms, restaurants, and retail units where a clean, unobtrusive installation is required. We install cassette units from all major manufacturers across commercial properties throughout Sussex.
For buildings where all air conditioning equipment should be concealed, ducted systems route conditioned air through ceiling voids with only slim grilles visible in the occupied space. Ducted systems are commonly specified for high-end office fit-outs, healthcare environments, and prestige retail.
Commercial kitchens require specialist air conditioning. We supply and install stainless steel cased units specifically designed for kitchen environments – resistant to oil, smoke, and steam, with dishwasher-safe filters to maintain hygiene standards. These are the only systems we recommend for kitchen installation.
Server rooms and data environments require tightly controlled temperature and humidity year round. We install precision cooling systems with close-control capabilities, providing the stable environment IT infrastructure requires. Redundant configurations are available for business-critical environments.
