No cooling call on a 2 year old Lennox AC Compressor not starting Capacitor tests good (45mfd) Ohm'd compressor windings, readings are good Put a hard start kit on, Compressor fired up Took hard start off, Compressor now starts normally Explained compressor could be starting to fail (way prematurely) Threw out the idea of putting in a heat pump (if the Compressor dies) and making it a dual fuel system to save on propane in the winter. Signed up for gold maintenance plan **we need to return asap to perform maintenance, the condenser coil is extremely dirty** 20x25x1 filter
