Don't have a clue. Didn't meet for secluded appointment got a call next day trying to send a tech a day late The tech did come out but I already had another company on the way. They reduced the service fee to ease the pain lol. He spent 20 mins most of which in his van then came in to tell me my 9 yr old unit is seriously broken and in need of repair and not worth in gave me over $2000 quote to repair and told it could be more as well. Also told me my friends in system is going to be ban and not redaly available told me I needed a new unit. Needless to say I declined the other company showed up and had me fixed and tuning in 30
minutes. The real problem I had ants in my compressor starter and wasn't getting power. Once tuning I was advised my ac wasn't low on freon it was overcharged and some had to be removed and very unlikely it had any leaks we have never had to put any freon in ! And furthermore my freon isn't ban it is the new kind. Glad I saved my self a lot of money
