I never use these guys but I thought I saw them releasing refrigerant into the atmosphere which is not good and highly illegal so I put a one star up the owner called me and discussed the one star it turns out I was wrong and he was just flushing the air conditioning line and no refrigerant was being released into the atmosphere he explained it all to me and I agreed with him he appears to be a very good businessman who takes pride in his business sorry because I never used them but if I need it I would and I’m sorry for any confusion
