What moves the price
- Complexity of the system — a multi-split or ducted system serving several rooms needs far more pipework and fitting than a single split unit.
- Specific requirements of the property — long pipe runs, thick walls or a hard-to-reach spot for the outdoor unit add labour to the installation.
- Additional features or custom installations — smart controls, zoning or concealed pipework add parts and fitting time to the air conditioning install.
- Type of system chosen — a ducted system takes far more installation work than a split or window unit.

How to pay less
- Cooling only the rooms that need it, such as a bedroom or home office, with a single split unit costs far less than a whole-house system.
- Placing the indoor and outdoor units close together, on the same wall where possible, shortens the pipework and cuts installation time.
- If you are already rewiring or renovating, fitting the air conditioning at the same time saves opening walls and ceilings twice over.
- Booking the air conditioning installation outside the summer rush can give you more choice of installers and dates.
Before you book
- Tell the installer which rooms you want cooled, their sizes and where you would like the indoor and outdoor units to go.
- You can ask the installer what servicing the air conditioning will need, so running costs are clear early.
- You can ask the installer to check whether your electrics can take the new air conditioning, or if an upgrade is needed first.
- Agree what the price covers, including the units, pipework, electrical connection, removal of packaging and a demonstration of the controls.
- Ask what warranty comes with the air conditioning units and the installation work, and how long each lasts.
- You can ask the installer how they will size and fit the air conditioning, as careful installation helps it run efficiently and last longer.
- You can ask whether the installer is qualified and registered to fit air conditioning and handle the refrigerant safely.
