High humidity. If an air conditioner is leaking, it's drain line might be clogged.
[Sc] This may also be caused by a cold air return filter that is either clogged or is too restrictive. Filters that are able to trap very small particles have a lower flow rate and can restrict air flow. This slowing of the air flow across the evaporator means that moisture in the air is more likely to accumulate and, in some cases, freeze and cause damage.
Additionally, a low Freon charge can cause Low-side temperature to below normal.
yes
Turn off the humidifier
To prevent condensation on AC registers in winter while the heat is running and the system is in the attic, you can improve attic insulation to reduce temperature differences, ensure proper attic ventilation to maintain consistent temperature, seal any air leaks in the ductwork to prevent warm air infiltration, and use a dehumidifier in the attic if necessary. Additionally, installing registers with built-in dampers can help control airflow and reduce condensation.
Yes. This will prevent heat loss and condensation.
If there is no air circulation between the insulation and the roof, it could get condensation, which ultimately could cause rotting.
Attic eave vents help to improve air circulation in the attic, reducing moisture buildup and preventing mold and mildew growth. This can also help to lower energy costs by reducing the strain on heating and cooling systems. Additionally, attic eave vents can extend the lifespan of the roof by preventing excessive heat buildup.
In winter, the humidistat setting for your attic fan should typically be set to a lower humidity level, around 30-40%. This helps prevent moisture buildup and condensation, which can lead to mold growth and damage to your attic insulation and roofing materials. Adjusting the humidistat ensures that the fan operates only when necessary, maintaining a dry and healthy environment in the attic during colder months.
Cut it off. An AC unit is supposed to remove the humidity from the air and condense it to water which you pump outside the house. I may not be clear on the problem here but I would try to prevent outside air from entering the attic.
The drip pan for the AC unit in the attic is full of water because it is designed to collect condensation that forms as the air conditioner cools the air. If the pan is full, it may be due to a clog in the drain line or a malfunction in the unit.
One of the biggest myths regarding roof vents is that they are only necessary in warmer climates. Ventilation is needed in all climates, however, to facilitate the exchange of fresh air as well as to avoid excessive moisture build-up. Moisture damage actually occurs more frequently in colder climates than in warmer ones. Without adequate venting in cold climates, attics are prone to condensation. Poor attic insulation, and not roof venting, causes drain on a home's heating system during the winter. It also leads to condensation which can cause rotting and other problems with roofing structure.
The noise shows that your attic is not well insulated. You need to get extra covering so the wind can not whistle through the gaps and make noises.
There is no difference between mold and mildew scientifically speaking. Mold in the attic can be covered if it occurs as a result of a covered loss... like a major storm removes shingles which causes a leak which results in mold. Attic mold that occurs as a result of ice damming can be covered as well.... ice damming is when snow builds up on the roof and then is melted from the bottom side from heat escaping from the house.... the water will back up under the shingles and leak into the wall cavities...this can be covered under most policies... Most attic mold however is the result of condensation which occurs when hot air escapes into the attic and condenses against the cold boards of the roof.....this is a result of improper ventilation and is considered to be an uncovered maintenance issue.... learn more at www.safemoldsolutions.com
