    Your criticism of my diagnosis reflects an unsound technical background.

    if it's a TXV system, could be a plugged equalizer.

    big john air

    i'm not a professional but i play one every day. check your blower cage for cleanliness. you will probabilly find it is filthy. apartment tenants are the worst about running a unit filterless and then getting mad later at everybody else when it stops cooling. if you don't know how to go about cleaning the blower then just ask me. i remember when i was a rookie there were plenty of smart ass veterans out there and looking at some of the responses given to you i see there still plentyful.

Problem is if pressures do not start rising fast enough sometimes unit will start freezing at evaporator. Unit does not freeze all the time just sometimes very infrequent. The air filter is clean, evaporator is clean, condensor is clean and evap. fan is running good on high speed. Could I have a restriction at the orifice, but usually the circumstances are the reverse of what i am finding. Any thoughts would be appreciated. The compressor was replaced in April 08 and has been running good up until about a week ago.
