Ducted air conditioning in Welwyn Garden City
The East of England is one of the sunniest and driest parts of the UK, which makes glazed rooms and lofts hard to keep cool. Ducted systems suit Welwyn Garden City loft conversions and new extensions where ceilings are being boarded anyway.
In an older house in Welwyn Garden City, the loft and any existing bulkheads decide whether a ducted layout will work. Welwyn Garden City sits around 13 miles from Watford, inside our Hertfordshire area. Postcode districts we cover here include AL8.
