Mold in Air Ducts and HVAC Systems in Kernersville

Mold in a Kernersville HVAC system usually grows on the evaporator coil, the drain pan or inside sweating ducts. It is priced after an inspection because the work ranges from cleaning a pan to replacing duct runs. If it has spread into rooms, indoor remediation runs $500–$6,000 in Triad-area pricing.

Where does mold grow in an air system?

• The evaporator coil and drain pan. In cooling season, water drips off the coil constantly. A clogged condensate line lets it stand.
• Supply ducts in the attic or crawl space. Uninsulated or poorly sealed runs sweat in humid air and wet their own insulation.
• Supply registers. Spots on the ceiling around a vent usually mean cold air meeting humid room air.
• Return ducts and the filter area, especially when a return pulls damp air from a crawl space.

Is it the ducts, or the house?

A system blowing musty air is not always growing mold. It may be pulling air across a damp crawl space or through a wall with a hidden leak. A good inspection opens the air handler, checks the coil and pan, looks at duct runs in the attic, and takes moisture readings in the rooms, so the fix goes where the problem actually is.

Why doesn't duct cleaning alone fix it?

Cleaning removes growth that is there today. If the drain line still clogs, the ducts still sweat, or the house still runs above about 60% relative humidity, the growth returns. Lasting repairs include clearing and protecting the condensate line, sealing and insulating duct runs, replacing moldy flexible duct rather than trying to clean it, and holding indoor humidity between roughly 30% and 50%.

What can you do today?

• Change the filter and check that it fits without gaps.
• Find the condensate line outside or at the drain and make sure water is flowing in summer.
• Look for water in the pan under the indoor unit.
• Run a dehumidifier if indoor humidity stays above 50%.
