Kaiser Air Conditioning & Sheet Metal was very good. I had them come out and inspect my AC unit and I ordered some replacement parts from them. The inspector was very nice and professional, and they were reasonably priced. It was a very good experience and I'm very happy with the job. The was only one little thing- they were supposed to call me and bring a vent filter over, but they haven't done that yet. They might still be sending it over right now, so there are no problems.
