Air Conditioner Refrigerant Line Sweating

During normal operation water vapors may condense on the outside of the lines carrying the refrigerant.

Air conditioner refrigerant line sweating.

Whenever there is a contact between the hot humid air and cold metal surface then there will be sweating or condensation on the metal surface so it is very important to have a proper insulation for the air handler ducts in case the portion of the duct is coming in contact with the. Improper or no insulation of ducts. Missing or damaged refrigerant line insulation insulation on the refrigerant lines particularly on the larger suction line will cause condensation and drips from the lines in humid areas. I took the unit apart it s a manufactured home a fancy name for a new newer mobile home.

Contact a professional if you aren t sure what sort of ventilation to add but it typically depends on cubic feet of air in the room as well as its location. Either way it is a symptom of a larger problem. Check that the condensation is being removed. When the evaporator coil freezes cold liquid refrigerant flows through the refrigerant line causing the surrounding moisture in the air to freeze.

So that s why the refrigerant line has ice on it. Sweating presents itself in an air distribution system as moisture that forms on the faces of lay in diffusers and t bar grids adjacent to those diffusers where this moisture collects and drips into the areas below. My air conditioning unit started acting up and was no longer blowing cold air it was barely blowing at all. In our photo at above left where refrigerant line insulation is incomplete the drip stains on the attic floor may well indicate a point at which leak.

If you are unfamiliar with air conditioning repair call a professional skilled in handling high voltage equipment and high pressure refrigerant. Use a refrigerant gauge set to check the pressures on the high and low side of the condenser. In such a case the refrigerant may cause the air outside the line to condense and then freeze. Sweating plumbing in these areas usually means that there isn t enough airflow to move humidity and hot air out.

There should be a constant drip when the air conditioner is running. Low refrigerant means low pressure and low pressure means low temperatures that will eventually freeze something called an evaporator coil. But when the pressure changes for some reason the refrigerant may start to act abnormally. The simple physics behind sweating is.

Installing more fans and vents can prove a very effective solution. While sweating may be a simple annoyance it may also be potentially dangerous. A sweaty compressor can be the sign of an overcharged system meaning it has too much refrigerant. Normally this is a very simple problem that can be fixed in less than 30 minutes.

Air conditioner condensation problems it is important for air conditioning preventive maintenance to be performed on your system to avoid problems. The condensation drip from the condenser is carried from the inside to the outside.
