Air Con Top Up

[J400uk]

A bit off topic but is there any air con top up etc available to come to your front door and do it outside

You can buy the kit from halfords and do it yourself if that's any help, http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_812353_langId_-1_categoryId_165632 and http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_812363_langId_-1_categoryId_165632 not any cheaper though
