Arrived to perform peace of mind service on unit less than one year-old. Checked cycled and tested all heating operations. Check reversing valve, defrost, and auxiliary heat function. Cleared drain line, tested all motors and capacitors. All motors and capacitors are within parameters. Refrigerate charge is correct. Tested airflow, and complete visual inspection of all components and coils. 24 x 24 filter inside the home looks like it could be replaced. All operations are a OK at this time. Thank you for trusting Dawsons with your heating and air needs.
