I have used CASA before for general maintainance on my home's AC unit, unfortunately when the condensor recently went out on my unit they said it would over a week to get out to my house and fix it. Yeah, like I'm going to wait a week to have my AC fixed in the middle of summer in Austin, TX. I found another company who had a technician out to my house with in hours to fix the problem. Needless to say I won't be going with CASA again. They just didn't seem to understand my situation and generally offered poor customer service.
Pros: Reasonably priced
Cons: Poor customer service, poor response to emergencies
