My first contact was Christine requesting for the Technician to call my cell prior to arriving since the house occupied. Christine very gracious and notified me when the Field Service Rep Shea would be arriving. Shea arrived shown him the area of the Heater and A/C unit and went right to work. He stopped explained what he was completing first the heating unit and then moved to the A/C unit.
Upon completion he reviewed each thing in detail which was great to understand what is being accomplished and not assuming it's complete. Great Customer service and great communication.
