Why is my suction line not sweating?
Sweating Suction Line. A sweating suction line is perfectly normal. Excessive sweating might be caused by not insulated well enough or too cold due to poor air flow over the evaporator. Some types of systems might sweat a lot because of being overcharged but in that case, usually the whole compressor will be sweating.Click to…

Hereof, what causes the suction line to get hot? Re: Reason for suction line very hot The external suction line running hot means it’s running on heat mode. The real suction line is inside the unit and runs between the reversing valve and compressor, that part shouldn’t be hot at any time.Also, how do I know if my liquid line filter drier is clogged? A symptom of a clogged liquid line filter drier is a temperature drop across the filter drier. Filter driers are typically shaped like a hot dog and are about the same diameter. Similarly one may ask, why is my liquid line sweating? Re: Liquid line sweating If Head pressure rises, so does temperature. In other words, restricted air flow = hot liquid line. That being said, some brands will meter refrigerant at the outdoor unit. If you have a system like that, its totally OK to see the the liquid line sweating.What can cause low suction pressure?This can be caused by low air flow (dirty filter, slipping belt, undersized or restricted ductwork, dust and dirt buildup on blower wheel) or a dirty or plugged evaporator coil. Checking superheat will indicate if the low suction is caused by insufficient heat getting to the evaporator.
