House was 72 and set at 72° when I arrived. Customer showed me a picture showing in the heat of the day it was 77° . Coil is clean but, charges are off a little. Trying to find cause. TXV bulb was not completely covered. Found problem . Inspection of duct I found no problems. Thought I did but it was insulation hanging down. Have good air flow. Need to order and replace TXV 6/11/21 Replaced TXV and dryer. Vacuumed down system and recharged system to factory specifications. After installing new TXV and charging I found that compressor has weak valves and not cooling properly. Pressure is running at 192 suction and 296 head. Need to replace compressor on system. 6/12/21 Installed new compressor, vacuumed down and recharged to factory specifications. Ran system diagnostic and technical data System is now working properly. Everything within factory specifications.
