Cooling · Decision Engine

Do I need air conditioning?

Cooling is a residual answer. This engine works out whether your house has done the honest fabric work first, and whether what's left justifies a cooling system.

Air conditioning gets sold as a comfort upgrade. It is genuinely one, on the right house. On the wrong house it is an expensive way to mask a fabric problem that never goes away.

We will read what we already know about your home, combine it with two quick questions you're best placed to answer, and give you a plain recommendation with the reasoning behind it. You can save the whole thing to your Home Brief at the end.

The reasoning appears here once the engine has read your answers.

If this were our house

We'd almost never lead with air conditioning. In most British houses the biggest gain comes from shading the worst window and running a proper night purge for a fortnight; that is what changes the answer.

Where cooling genuinely is the answer, one properly sized inverter split in the room that needs it beats a multi-split trying to condition the whole house. Quiet, cheap to run, and honest about the problem it is solving.
