Multi-split air conditioning in Derry/Londonderry
In Northern Ireland, cooling is mostly needed in conservatories and glazed rooms, while efficient heating benefits the whole home. In a house in Derry/Londonderry with a usable loft, multi-split pipes can often run through it so the front stays clear.
Multi-split is a good fit for Derry/Londonderry flats and maisonettes where only a balcony or one rear wall is available. We cover Derry/Londonderry and the rest of County Londonderry, including Coleraine and Limavady. Coverage includes BT48 and BT47.
