Newburgh, IN - Responded to cooling insufficiency complaint on lower floor of residence. Upon investigation, confirmed thermostat had been relocated from lower floor to upper floor, resulting in inadequate temperature control for lower level zones. Measured airflow at lower floor register using digital anemometer, recording 285 FPM output. Explained to customer that thermostat placement on upper floor causes system to satisfy cooling demand based on upper level temperature readings, leading to premature cycle termination before lower floor reaches desired temperature. Recommended relocating thermostat back to lower floor or installing zoning system with multiple thermostats to properly control temperature in multi-level residence.
