Installation of air conditioning systems

Split air conditioning systems incorporate refrigerant gases and therefore need to be professionally installed. Some systems, do offer flexible, pre-gased hoses with quick fit connectors. These allow installation by a competent DIYer and therefore can help reduce cost of a wall-mounted air conditioning system. However, any ac system requiring copper piping and flange connections must be installed by a trained and qualified contractor otherwise illegal refrigerant leakage and severe accidents can occur.
 Commercial or industrial installations (BN, PO, BH, SO, GU & RH postcodes only)
We offer a free site visit and quotation service for commercial installations in the above postcodes. Call 01903 858608 now to book your visit. We will have an engineer to you within five working days and you should receive your quotation back within three working days from that date.
 Domestic or light commercial installations (BN, PO, BH, SO, GU & RH only)
We have a set fee of £750 to install a single 2kW, 3.5kW or 5.3kW Hacienda wall-mounted air conditioner in a domestic situation and £1,200 to install a Symphonia 3.5kW or 5kW cassette ceiling mounted air conditioner (subject to the conditions below). This price does not include the air conditioner itself or electrical connection to your mains electricity supply. Due to regulations governing connecting installed appliances to an electrical system, you will need to have a Part P qualified electrician make the final wiring connection to a 13amp fused spur. This can be done anytime after the installation in complete.

This installation service includes:
  • Installation of the external compressor unit directly on to the outside of the building at ground level or at a maximum height of 1m with brackets supplied by the installer.


  • Mounting the indoor unit on the inside of an external wall (wall-mounted unit) or in a suspended ceiling void (ceiling mounted) no more than 10m from the external unit.


  • Connecting the indoor unit and external unit with up to 10m of copper refrigerant pipework, passing through one standard brick cavity wall.


  • Connecting a gravity drain to the inside unit terminating at ground level externally (secured to the refrigerant pipework), and a drain from the external unit to a suitable place of termination up to 3m away.


  • Covering all internal pipework with plastic trunking and the external pipework with black foam.


  • Sealing holes made through brickwork with mortar.


  • Connecting the electrical wiring (up to 10m) from the inside unit to the external unit, secured to the refrigerant pipework.


  • Connecting the finished air conditioning system to a temporary power supply to commission it and give a customer demonstration of its features.


    • Once ordered, you will be contacted by phone within two working days to arrange a convenient time in the next 3 weeks for the installation to take place.

    Please note: In some areas of the UK it is necessary for you to obtain planning permission to mount an external air conditioning unit to a building. It is your responsibility to gain this permission in advance of the installation.
