    30 year old GE central unit 5- ton

    how much freon would a 5-ton general electric central air unit hold the unit is around 30 years old. started with a suction pressure of 60 and head pressure of 250. to get it to 70 on suction pressure had to put 10 lbs of freon in. the air handler, heat exchanger and evaporator are as big as a rerfigerator.
    makes sense that a bigger evaporator would hold more freon but that much?
    thanks gwalk

    I wouldn't worry about how much refrigerant it's supposed to hold, because the charge probably changes the second you finish topping it off. (leaks)
    General public's attitude towards our energy predicament: "I reject the reality of finite resource depletion and substitute it with my own; energy is infinite, we just need an alternative storage medium to run the cars on. The economy can grow indefinitely - we just need to "green" everything! Technology is energy! Peak what?"

    O.M.G. Stop adding refrigerant before you hurt somebody! Get someone to check it out who understands superheat, subcooling, etc.
    Anything I say here is only my opinion. Even if you understood what I said.... What I said may not even be what I meant.
