Ducted air conditioning across Renfrewshire and Inverclyde
For a renovation in Paisley, the best time to plan ducted cooling is before the plasterers arrive. Ducted systems suit Paisley loft conversions and new extensions where ceilings are being boarded anyway. Mild Scottish summers mean cooling matters most in conservatories, lofts and rooms with large windows.

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
Outdoor units on Scottish homes can often be installed without a planning application, but the conditions differ from England's, so we confirm the rules for your property at survey.
The survey
On a survey in Renfrewshire and Inverclyde the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. 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.
