Air conditioning for extensions and kitchen-diners in Carnforth
In Carnforth, a side wall of a single-storey extension is usually the neatest place for the indoor unit. In the North West, heating efficiency is often the main benefit, with summer cooling a welcome bonus.
For a kitchen-diner in Carnforth, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Carnforth lies roughly 25 miles from Preston, and we cover it as part of Lancashire. Postcode districts we cover here include LA5.

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 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
