C takes a long time to cool house
I have a central air unit with a Heil logo on it, and on top it says ''high efficiency'' with a big ''5000''. I was hoping to find a manual for it; Google is not much help yet. What I'm wondering is, if I went and got (a) refrigerant gauge(s), what readings should I see? Since it takes a long time to cool my (1188 sq. ft.) house, I suspect there is insufficient refrigerant in the system (blows cool but not really cold). I saw in their latest mailed ad that a particular national chain of tool stores (with the initials ''HF'' :-) ) sells both the gauges and R134A refrigerant. (I'm not even sure if the system uses R134A.) I don't know too much about this unit as it was already installed when I bought the property.

The system should be either R-22 or R-410A
You need to go outside and feel the suction line (the big line) with the unit running, after the house is cooled down, it should be cold and sweating,if the humidity is not to low, if it is your unit is probably ok. High Effeciency units
usually have a higher suction pressure and temperature and can run longer, if it's sized right. After the house is pulled down to temperature and starts cycling, it should come on and go off about 3 times per hour. The longer the unit runs the more dehumidification it should do.
