Hello, a good technician will generally capture all of the refrigerant in the compressor unit...however 55 feet between the furnace and AC unit is quite long, and more refrigerant needs to be added so that system runs properly... it takes an experienced technician to install the correct amount... some will put a few ounces too much refrigerant in... causing the evaporator to run warmer than it should and that will reduce the cooling capacity.
There is another issue, if the 2 ton rated refrigerant lines were left in place when you installed the 3 ton unit, the lines will be too small for proper operation.
Summary: Its a tricky refrigerant amount situation at best, ***** ***** small refrigerant lines at worst. Not all of todays techs are up to speed on the finer points in those regards.
Please rate my work., its how I earn a living and will not increase your charges.
Hello again, good work on fitting the properly sized refrigerant lines..
The units themselves are charged from the factory for the typical (minum) line length not save money so much as to avoid an over charge of refrigerant (a small over charges warms the cooling coil and a large over charge is fatal to the compressor).
I will put the 'rate your expert' box up so that you can rate my work, thats how I earn a living and will not affect your charges.
Hello again, how are you doing with it, Let me know, we can go from there.
