What is your question?
Compressor running clutch engaged warm line into heater box and low pressure reads at 50psi. All fuses look good. I suspect that coolant needs to be topped up.
What makes this problem better or worse?
Nothing.
How long has your 2014 Ford F-250 Super Duty had this problem?
Just tried today. Worked last summer.

Working with refrigerants requires specialized tools and certification to legally handle them. If your clutch is engaged and cycling normally, but you aren't getting cold air, it could be something other than a state of charge issue. Air conditioning problems can originate by one of the following general areas: 1) A problem with the refrigerant system. Meaning, the refrigerant used has escaped and there is not sufficient refrigerant to pressurize the system properly, resulting in hot air. When this happens, the system must be checked for leaks, the leaks repaired, and the system recharged. 2) A problem mechanically or electrically with the under hood components. If the compressor has failed, it will not allow the system to operate. Further, if the system becomes contaminated with debris from a failed compressor, this can be even worse. Electrically, the coil of the compressor may not be working properly, or a cycle switch could fail preventing the system from operating. If your condenser fan is not working, the system may not work properly also. 3) Climate control problem inside the vehicle. If the system that operates the heating, ventilation and air conditioning system fails to operate properly, then the under hood components may not be turned on or off properly, keeping the cold air from being produced. Only testing these systems will yield a direction and an eventual result.
Low side line MUST be COLD while a/c is engaged ! IF low side line remains warm / ambient temperature then a/c isn’t operating correctly.
