During this visit I performed a fall heating maintenance on the rooftop unit that serves the office and waiting room. The unit was checked for both electrical and mechanical functions. All heating checks are in range today. In addition to this the condensation drain was removed and cleaned, the insulation for the blower compartment door was reattached on the corners with adhesive and the filter was replaced.
