Is the HVAC guy shooting me straight on freon amount needed?


I had a tech over to check my freon level, R22. It was 81 degrees outside. The temp was set at and holding at 72 degrees inside the house. My outside unit badge says 150 low side, 300 high side. The readings he was getting was around 200 psi on the low side, and down towards 100 psi on the high side. He said I would need 2-3 lbs of R22. Does this sound about right?

He was using Yellow Jacket gauges like these, if it matters.

I'm mainly concerned with him overcharging the system as it's almost 25 years old. Thanks!

Sorry.... we can't help you with your questions. The administrators of DIY have requested that system charging and pressures not be discussed in the forums as they require the services of an EPA certified tech. In this case I can only recommend you trust the technician you've hired.
