Air Conditioner Refrigerant Line Sweating

Low refrigerant means low pressure and low pressure means low temperatures that will eventually freeze something called an evaporator coil.

Air conditioner refrigerant line sweating.

The line is a pvc pipe that runs from the condenser inside your house to the outside next to the compressor. If you are unfamiliar with air conditioning repair call a professional skilled in handling high voltage equipment and high pressure refrigerant. The condensation drip from the condenser is carried from the inside to the outside. 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.

In such a case the refrigerant may cause the air outside the line to condense and then freeze. Okay the heating and air conditioning unit is inside the house with the outside blower condenser i guess it is. Installing more fans and vents can prove a very effective solution. 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. 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. My air conditioning unit started acting up and was no longer blowing cold air it was barely blowing at all. Normally this is a very simple problem that can be fixed in less than 30 minutes.

But when the pressure changes for some reason the refrigerant may start to act abnormally. Improper or no insulation of ducts. Check that the condensation is being removed. So that s why the refrigerant line has ice on it.

There should be a constant drip when the air conditioner is running. 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. Condensation water leaking near the air handling unit can be avoided with proper air conditioning repair and preventive maintenance. Sweating plumbing in these areas usually means that there isn t enough airflow to move humidity and hot air out.

The simple physics behind sweating is. While sweating may be a simple annoyance it may also be potentially dangerous. During normal operation water vapors may condense on the outside of the lines carrying the refrigerant. Use a refrigerant gauge set to check the pressures on the high and low side of the condenser.

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. A sweaty compressor can be the sign of an overcharged system meaning it has too much refrigerant.
