New build and renovation air conditioning in Carmarthen
First-fix pipework in Carmarthen extensions goes in while the joists and studs are open. In South and Mid Wales, efficient heating is often as important as cooling.
Renovations in Carmarthen are the easiest jobs to make invisible, because the pipework goes in before the plaster. We cover Carmarthen and the rest of Dyfed, including Llanelli and Ammanford. Postcode districts we cover here include SA31.

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%.
Working with your builder
First-fix work is about coordination, while the outdoor unit follows the normal planning rules for the property.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
