Home air conditioning

Home air conditioning keeps rooms comfortable through hot summers and, with a modern reversible system, can warm them efficiently in winter too. This guide explains how it works, what it costs, and how to choose the right system for your property.

Cooling that can also heat

Most modern fitted systems are reversible air-to-air heat pumps. They move heat rather than generating it — out of your home when cooling, and into it when heating. In practice that means one discreet system can cool a room in July and take the chill off in winter, often more efficiently than direct electric heaters.

Which system suits your home

• Single split — one indoor unit for a single room such as a bedroom or home office.
• Multi-split — several rooms from one outdoor unit.
• Ducted — concealed distribution for a whole-home approach.
• Without an outdoor unit — for the rare cases where an external condenser can't be sited.

Not sure? The system finder gives a preliminary recommendation from a few details about your rooms.

What it costs

Most homes spend £1,500–£3,000 for a single-room system and £4,000–£8,000 or more for multi-room or whole-home installations — the figure depends on your property. See the cost guide and running costs, or get an indicative range from the cost estimator.

Rooms and property types

Air conditioning is popular for bedrooms, loft conversions, flats, new-build homes, period properties and whole-home projects.

Permissions and practicalities

Check whether you need planning permission, where the external unit will go, likely noise levels, and the installation process.
