tech arrived and found that the unit was operating properly. The tech then performed a visual inspection of the unit and found that there were no error codes on the furnace. The customer explained to the technician that the only thing that he’s done to the system was changing the filter. The technician looked at the previous filter that was in the system, and believes that the dirty filter was causing the unit to come off on high limit. The technician recommended further inspection of the units to ensure that there is nothing wrong with the unit. The customer denied further inspection. Upon customer request, the technician strapped up the vinyl tubing coming from the condensate pump into an interior drain. The technician also scheduled an install supervisor to come out to the home to quote stuck work renovations due to the customers request.
