Ducted air conditioning in Larne
In an older house in Larne, the loft and any existing bulkheads decide whether a ducted layout will work. Northern Ireland's mild, damp climate makes efficient heating and dehumidifying the main benefits for most homes.
Ducted systems suit Larne loft conversions and new extensions where ceilings are being boarded anyway. Larne is about 18 miles from Belfast and falls within our County Antrim coverage. Homes in BT40 are all within our coverage.
