Performed preventative maintenance on the systems Cleaned drain, checked/ cleaned filters, tested/inspected all electrical components, checked refrigerant pressure, tested operation of both systems as a whole in both heating and cooling modes. I found that the capacitor on the Maine unit was weak so we replaced this I also found both supply and return plenum to be leaking air. I also found that there is some dirt starting to form in the evaporator. We will provide an estimate to correct both of these things.
