Multi-split air conditioning in Porthmadog
In a house in Porthmadog with a usable loft, multi-split pipes can often run through it so the front stays clear. Mild North Wales summers mean heat pump heating is usually the headline benefit.
Twin and triple systems suit Porthmadog homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. Our Gwynedd coverage takes in Porthmadog, about 21 miles from Bangor, Gwynedd. Postcode districts we cover here include LL49.

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.
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. Surveys in Porthmadog cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
