I rang to find a time to have my a/c looked at, knowing that it would not be a half hour job. Eric suggested I bring it in that day, just so it could be analysed. Well, they actually worked on it for a couple of hours, even though they were busy.
We are still not sure it has been fixed, but it is blowing cold air for now and if the dye leaks, they will then have a better idea what the issue is.
I just need to say I consider that to be fantastic service and I am very thankful.
