Condensation In Attic From Air Conditioning

Air handling units in attics should have a secondary condensation pan in case the primary condensation pan overflows.

Condensation in attic from air conditioning.

Condensation condensation forms when the water vapor in the air drops out of suspension and condenses into a liquid form. As the humidity level rises outdoors condensation will gradually begin to form on the surface of your air conditioning ducts. The colder the air is inside the duct the greater the chance of ductwork sweating. Water builds up in the ceiling and eventually there will be a drip if the homeowner is lucky.

Poor insulation can cause condensation to build up within your system and drain via the ac vents. The colder the air the more likely it is that water will condense. The condensation drip from the condenser is carried from the inside to the outside. The air in your vented attic is hot and humid just like all outdoor air in florida.

Condensation from uninsulated ducts the problem. The condensation drain line is plugged.

Check that the condensation is being removed. Improper or no insulation of ducts.
