Multi-split air conditioning in Ammanford
South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year. In a house in Ammanford with a usable loft, multi-split pipes can often run through it so the front stays clear.
Multi-split is a good fit for Ammanford flats and maisonettes where only a balcony or one rear wall is available. Ammanford is about 14 miles from Carmarthen and falls within our Dyfed coverage. That includes the SA18 postcode district.

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
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.
