We had an evaluation of the problem on Tuesday, and the soonest they would repair the coils was Saturday. They did the service Saturday, but the drain line was not correctly assembled, and I had to call on Sunday and on of the technicians from Saturday re-assembled the line and corrected the problem. However, Monday I still had a hot house and the AC was running non-stop. I called and was told I would have to pay for after hours service to look at the problem. I indicated that this was a continued problem with their installation and that I wanted to speak with a manager. The technician called back promptly and said he was on his way and there would be no additional charge. The new technician informed me that the freon was low and that possibly the installation on Saturday may not have been correct accounting for another leak. He said to call on Tuesday if the house was not cooling properly. The house was cool this morning, so I am hopeful that the Saturday technicians just did not put enough freon in the system. I am quite worried that I will not know that the problem was solved until I get home today and see the usage on the unit.
