This home in Stafford VA was experiencing HVAC Duct Sweating. This happens when cold air is travelling through hot metal HVAC ducts creates condensation. This can show up as water stains in the drywall near the ducts and can lead to mildew or mold if not addressed quickly enough. An effective solution for this problem is to encapsulate the HVAC ducts in spray foam. Spray Foam not only closes off the ducts from the hot air around them but it can help seal and small gaps or leaks in the duct system, allowing for more efficient delivery of the conditioned air to the rooms in a home it is intended to make more comfortable.
