What is the ballpark pressure when totalling freon to Coleman AC model brcq0361cb?
65-70 on suction side, that is big copper tube
stay cool
There is no ballpark, it depends on the outside temperature, the indoor heat, is the condensing unit clean, is the evaporator coil verbs, are all the vents unscrew in the house? If you add too much you can really mess up your condenser, and formulate the compressor useless. If you must add freon yourself, make sure the suction queue is beer can cold, but I high recommend not attempting to do this yourself if you know nothing in the region of pressures and temperatures of a refrigerant system, plus you really should have an EPA Type two license to preform this. You can't even buy the stuff lacking a license.
Answers: If your using r-22, you want your suction pressure above 58# of pressure to keep the unit from freezing up, and you don't want the soaring side pressure running over 275#. If the system is clean inside and out I usually try to run about 65-70 # low side and 250#+or- 10# if it is hot outside. You don't want the pressure over 275 Ideally you want the needles on the gauge to parallel. try to get most system in the warmness of the day to run 250 over 68-70#. Good luck and God Bless.
