Installation & the rules that apply

This is a single split. This is where regulation bites. Breaking into the refrigerant circuit must be done by an F-gas certified installer (in the EU and UK), and single-split systems may use refrigerant indefinitely only if its GWP is under 750 (R32 qualifies). DIY voids the warranty, home insurance and is an offence. The outdoor unit alters the facade, so a prior declaration to the town hall (e.g. France), planning permission, or freeholder, landlord and condominium consent is commonly needed, plus heritage rules in protected zones and minimum-distance and noise rules toward neighbours.
