Ductwork

There is mold on one or more of my vents.

Mold on your vents usually indicates the presence of mold in your ductwork. Duckwork starts at the air handler. You'll need to do the following:

1. Have your air ducts cleaned/sanitized.

2. Install a UV light in the air handler.

3. Have the air handler cleaned/sanitized.

There is mold on the outside of one or more of my vents.

Mold present on the outside of a vent indicates high humidity/moisture at that location. This can be caused by one or more of the following:

1.  Ductwork/boots that are not fully sealed at the vent, causing air leaks which produce moisture.

2.  Insufficient levels of insulation in the attic causing an inadequate buffer between the temperature of the conditioned air in the room and the temperature of the air in the attic, causing moisture.

3.  Air leaks in your ductwork causing moisture.

4.  Mold in your ductwork.

Solution is to ensure all of your ductwork/boots are fully sealed, ensure your level of insulation in the attic is sufficient and to have a duct cleaning.

One or more of my rooms are warmer or cooler than the other rooms.

You may have clogged or damaged runs of ductork to those specific rooms. The run(s) may need to be cleaned, repaired, or replaced.

There are wet marks on my ceiling.

You may have openings in your ductwork, which is causing significant condensation. 

Your ductwork may need to be repaired or replaced.
