With efficient and reliable air conditioning in your workplace, you can create a more comfortable environment for staff, allowing them to work to the best of their ability, regardless of the humid temperatures soaring outside. A professionally installed air conditioning system should be climate-responsive — heating, cooling, dehumidifying and cleaning the air. Denmanair's experienced technicians only install top quality units from leading manufacturers such as Mitsubishi, Daikin, Fujitsu, Toshiba, Samsung and LG.

We provide the highest-quality climate control solutions and pride ourselves on delivering exceptional air conditioning service and aftercare. Our engineers will ensure you can continue maintaining a comfortable environment for staff and customers, with a serviced AC system working as efficiently as possible.

Clean air, quiet operation and cutting-edge features

Many leading-edge units feature sleep mode, a novelty if you have a unit in your bedroom. The compressor will run slightly slower, so you're not kept awake by the humming.

Air conditioning is quickly becoming a necessity in homes across the UK, with a Met Office Report stating the duration of warm spells (when temperatures soar above average) has more than doubled in the last 50 years.
