Air conditioning for extensions and kitchen-diners across County Antrim
For a kitchen-diner in Belfast, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. In Belfast, a side wall of a single-storey extension is usually the neatest place for the indoor unit. In Northern Ireland, cooling is mostly needed in conservatories and glazed rooms, while efficient heating benefits the whole home.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
Northern Ireland has its own planning rules for outdoor units, and conservation areas and listed buildings need particular care. We confirm the position for your property before installation.
