Measured, cut, flared and insulated (using ISO Quality products and class’O’ flame retardant insulation and cable) by our own Engineers…… This will allow you to choose various options… Both ends of the pipework will be flared and fitted with the flare nuts ready to connect to your system. We Have all the tools and materials in our workshop in Kent to make up any length of 1/4″, 3/8, 1/2″, 5/8″ or 3/4″ Copper (Refrigeration Quality) pipework complete with 9mm thick insulation applied to it for your air conditioning installation.

I Can also supply the following: (Message me for actual costs at any time). Basically anything else you require to have a split type air conditioning unit installed. The installation should be carried out by a certified F-Gas engineer, but you know that! PS: If you are also looking for a quality AC system then we have available in our stores at least 10 systems (2.5kw and 3.5Kw) of DAIKIN Wall and Ceiling Mounted inverter’Heat Pump’ split systems (Brand New Boxed) Please message me. For prices BUT these are not your basic models found online, these actually work after 3 years………. Unlike loads of others, but they wont be as cheap. The installation of air conditioning, refrigeration and heat pump pipe work (including split systems), should only be completed by qualified staff holding the necessary’F-gas qualifications’ and certificate. I do not encourage the use of DIY installations at all!! As the gas pressures, environmental and’health and safety’ issues are complicated and dangerous if not adhered to correctly.
