    For a straightforward single air conditioning system, installation will usually take around 4 to 8 hours, so most jobs can be completed within a day.

    More complex installations can take longer, particularly where several indoor units are being fitted, pipework runs are longer, access is difficult or an existing system needs to be removed first.

    Before work starts, we’ll explain what is involved and give you a realistic idea of how long the installation is likely to take.​

    What happens during an air conditioning installation?

    1. Prepare the work area and confirm the installation plan.
    2. Fit the indoor and outdoor units.
    3. Install insulated refrigerant pipework between the units.
    4. Connect the electrical and control wiring.
    5. Install condensate drainage.
    6. Connect the system to the electrical supply.
    7. Pressure-test the pipework and check for leaks.
    8. Evacuate the system and prepare the refrigerant circuit.
    9. Test and commission the system.
    10. Clean the work area and show the customer how to use the system.

    Our engineers will then ensure that the system is working effectively and the customer has been shown how to use the system and that they are satisfied with the completed installation.

    The customer will be provided with an information pack including contact details, instructions, features and information about maintenance and warranty.

    What happens during an air conditioning installation?

    The installation normally includes fitting the indoor and outdoor units, installing insulated refrigerant pipework, electrical and control connections, condensate drainage, pressure testing, commissioning and final testing. Once complete, the system will be checked and you will be shown how to use it.

    Will there be much disruption while air conditioning is being installed?

    For a straightforward installation, disruption is usually limited to the room or areas where the equipment and pipework are being fitted. Our engineers prepare the work area carefully and clear up once the installation is complete.

    How soon after ordering can my air conditioning be installed?

    Installation availability can vary depending on the time of year, the equipment required and our current schedule. Once your system has been agreed, we will confirm the expected installation date before the work is booked.
