Duct services in Three Lakes: test, seal, repair, clean

We look at the duct runs in the attic, the supply and return registers, and the insulation around those runs. Houses and townhomes make up most of the homes here, and attic space can push warm air around the ducts. That changes how we check for loose joints, crushed sections, and gaps at the registers. Insulation on the duct runs matters because it helps separate the ductwork from attic heat.

Half of the homes here were built by 1997, and newer homes can be tighter inside. That changes how we check the return paths and the duct connections that move air back to the system. If the returns are small, blocked, or unbalanced, rooms can hold moisture. We also look for sweating on duct surfaces, because that tells us the ductwork and the indoor air are not matching well.

We still focus on the ductwork inside the house, especially if the ducts run through the attic. Full sun on the outdoor unit does not change the attic heat, but it can make the supply and return checks more important when we test airflow and static pressure. In these homes, we also look at duct insulation and sealing, since warm attic air around the runs can affect what reaches the registers.
