Can anyone recommend: Re-Gas Air-Con System

Most older units use a gas that is no longer allowed and therefore need to be replaced. First thing to do is check on the type of gas you have in your unit, this information will be in the manual or you can look it up on the internet, then you can look it up and find out whether or not your units can be regassed. I have just been through this process and I am going to have to replace all my units.

Thanks. Will do
