One a/c unit was working fine and the other was not blowing cool air. The service man said it needed about $1000 for 2-3 parts but it would not be worth repairing. He told me I needed two completely new systems priced at $17k-$24k. Then he just talked about financing the new systems and even asked if he could to run a credit check. He did nothing to fix the unit and did not even identify the issue. Just selling new systems!
