Air conditioning for extensions and kitchen-diners in Ammanford
An extension in Ammanford with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer.
For a kitchen-diner in Ammanford, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Our Dyfed coverage takes in Ammanford, about 14 miles from Carmarthen. Postcode districts we cover here include SA18.

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.

We book surveys in Ammanford at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
