Today these guys wanted 8k to replace one of the AC units and they said that was for the cheap one and a good one would be 14k. Then they said the part that's in the attic that dispenses the air needed to be replaced as well but when he went and looked at it he said the other one for the other AC unit was in the way so he would have to replace them both. At this point it sounded like a scam.
Then they said they would leave a portable unit there for us overnight because there are two newborn babies in the house. But when they weren't sure we were going to spend 10k + with them suddenly they didn't want to leave the portable.
Needless to say we decided to get another quote and remembered there was an AC guy at church. He said if we wanted to spend 10k we could have a weekend at The Red Rock with the families and have a ton of fun AND fix the AC.
If you go with this company I would recommend getting a second opinion.
UPDATE: the repair cost 150$.
