I've heard of it, but never have seen it until this week.
Last week, a walk in freezer low on gas had over an inch of ice on the
liquid line and non on the suction, 9 degrees outside box was 49F
This week, homeowner called and said water all over the floor of his
basement. I go over there and the air conditioners liquid line has over 1
inch on it about five feet from the outside wall, and over two inch's
outside. Now this is interesting........... Oh, the unit wasn't running.
Will a TXV take care of this problem or do I need to install a solenoid
valve? I wonder how much energy is lost in a years time with this transfer
of heat from a forced air unit to the condenser? But what is confusing, 3/8
inch liquid line acting like a cap tube? You would not think there would be
a pressure difference in such large lines on the outlet of a condenser.
Hmm, wonder if they soldiered the line almost closed when they installed
this, the entire installation is a mess as it is.
