cut the heater on and thaw it out, or use the old hair dryer then check pressures

You don't just need to know the SH. If your return air is to cold it can also cause a freeze up. It feels like you are focused on a smaller part of a larger picture. I work in commercial HVAC my shop did work on more then 450 units last year. We used less then 300 lbs of R-22 last year and I know 80lbs of that was on two large systems. Not enough refrigerant is vary rarely the problem.
