Insulating Ac Lines In Attic

Refrigerant line insulation refrigerant line insulation is partially responsible for the efficiency of your air conditioning system operation.

Insulating ac lines in attic.

Anytime a liquid line is ran through an area of 120 degrees or more it is recommended that it be insulated. Two different diameter copper refrigerant lines run between the air conditioning system condensing unit house exterior and the ac coil named after its shape installed inside the house sometimes crawlspace or attic contained within its own compartment. I ve read that in a couple of mfgrs literature and was told that recently in a tecumseh seminar. 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.

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 stains or even mold appear on the ceiling below. Replacing ac pipe insulation if your air conditioning system s pipe insulation has degraded you may be spending more than is necessary to adequately cool your home. Put it in an attic full of blown insulation and you re forcing it to work harder to vent its heat. A clog in the drain line of an attic ac unit is a homeowner s worst nightmare.

A powerful wet dry vac and proper hose attachment can take care of most jobs. It can potentially cause extensive and expensive water damage. The recommendation also calls for 1 2 instead of the standard 3 8 armaflex.
