Ducted air conditioning in Bangor, Gwynedd
In an older house in Bangor, the loft and any existing bulkheads decide whether a ducted layout will work. Exposed coastal sites in North Wales call for outdoor units placed out of the wind and salt spray where possible.
For a renovation in Bangor, the best time to plan ducted cooling is before the plasterers arrive. We cover Bangor, Gwynedd and the rest of Gwynedd, including Caernarfon and Dolgellau. Coverage includes LL57.

Planning and permissions
Since 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.
