12FEB2024 Jason Brown Arrived for club renewal/ fall tune up service. Spoke with homeowner about the systems Performance. It’s working well I’ve been in the home for about four months now. It worked well even in the very cold weather. Inspected furnace coil, and ac. Found the system to be an 18 seer Amana with inverted dc motor. Cleaned flame sensor, checked through safeties, inspected heat exchanger, blower wheel, motor, pressure switches and all components at the furnace. Checked UV Bulb and 20x25x5 filter. Verified no errors in system history. Measured heat rise and delta temperature. Found ductwork in attic has lost its vapor barrier. And found the kitchen exhaust aimed at an attic vent. Discussed findings and airflow/ductwork. System is working properly at this time.
