copper tube not "cold"


thats the one. looks just like a can that has the liquid line running in/out of each end. should be a bi flow in a heat pump so the refrigerant can travel both ways but any tech will tell you a story of a single flow put in a heat pump or with flow arrow pointed the wrong way. I caught one of mine right before lighting the torch....


on the heat mode you dont need much just a couple of minutes - if it is too warm out it is not good for the system and often has a hi-pressure switch that will cut it off as a safety.

the filter/dryer is just a spot that can be suspect the other is the outdoor metering device but it dosent matter you just want to know where the frost stops.

At some point you will need an EPA certified tech out to deal with it since it unfortunately has to do with refrigerants. The heat trick has worked in the past for me a few times and thats an easy DIY.

Take it ez climbing up/onto the rooftop and good luck!!!

not sure how much refrigerant your unit holds. There will be a nameplate on the condenser with that info and then some is added due to the length of the copper lines to your air handler.

I think the first couple of answers thought you were talking about ice on the suction line and on the evap coil. That is way more common and what I usually see. When you said liquid line it changes the whole situation.
