Performed the level 2 package cleaning. Furnace: Burners and flame sensor are clean. Heat exchanger looks good. Drain is clear. No CO detected in the air. Heat rise was 43Â°. Only thing I found was the excessive air was a little high. Not concerning at the moment. AC: No leaks detected. Electrical components tested good. Condenser coil is clean. Refrigerant pressures were normal. Subcool was 8Â° with a 17Â° temp split. All equipment is operating properly.
