Hello everybody. I'm new to the forum so please be gentle!
Been in the office too long, I'm looking for help with the quickest method of recovering refrigerant from a large a/c system. This consists of 2 D/X coils with separate cond units on a roof 2 floors above. I have heard of the push-pull method, not sure what it entails, if someone could enlighten me would be most grateful. Any help appreciated. Cheers.
