You must, must, ensure that liquid does not enter the low/suction range.Most technicians in the HVAC field know the normal range of operation for the low-pressure side of an air conditioning system. This tends to be around 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A and is dependent upon operating conditions. On the high-pressure side of the system, there is a wide variation in pressure due to the ...This video shows how to check a refrigerant charge on an ac unit.

Over time, refrigerant can leak out of an air conditioning system, keeping it from doing its job. A Freon recharge is a very common AC repair, though if you need one, there's probably also a leak somewhere that needs repairing. The average refrigerant refill cost is $200-$640 for a central AC unit, though fixing the leak may cost more.

As R-22 phases out and units that use the refrigerant become more and more scarce, its price, due to rarity, has increased to match the additional demand and scarcity of the product.Well, you can't charge to the high side. It should be obvious that the output of the compressor is going to be a higher pressure than the R-410a in the bottle at ambient temp. I have never done R-410a yet but as I understand it you charge liquid to the low side but *slowly* as to allow it to vaporize on the way in so it doesn't slug the compressor.
