Well yes, and thank you also, but it was just a WAG in the first place, I thought I might suggest it could be a heat pump in the second place, but thought I'd make a simple guess that had nothing to do with the unlikely possibility that any of it was related to a "leaking" condenser in the third place. The OP clearly doesn't know what they're looking at, so pointing out a likely, and probably the most likely, possibility.....seemed reasonable. Apparently not. "Making a WAG because we have no good descriptions yet."...... (I can explain what that sentence means if anyone is unclear on it......)
