Ducted air conditioning across County Antrim
In an older house in Belfast, the loft and any existing bulkheads decide whether a ducted layout will work. Ducted systems suit Belfast loft conversions and new extensions where ceilings are being boarded anyway. Damp Northern Ireland winters make a heat pump's dehumidifying mode useful well beyond the summer.

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.
The survey
A survey in County Antrim usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
