Silver club Fall furnace tune up. Spoke with customer and they recently changed their access ladder. Fresh filters were left in attic for us to change. Checked filter cabinet and filter in the unit still has plenty of life in it. Checked flue, evap coil, heat exchanger, blower, blower capacitor, cleaned flame sensor and cycled system on. Checked amps, heat rise, static pressure and gas pressure. System is working great at this time. Helped customer change batteries and went over thermostat controls with them. KianooshM
