Duct Repair & Sealing in Houston, TX
In a typical house, 20–30% of the air moving through the ducts leaks out. In a 140°F Las Vegas attic, that leak means paying to cool the attic. A duct leakage test finds out how bad it is, then techs repair the disconnects and seal the joints with mastic or an aerosol sealant.

Duct Repair & Sealing in Houston: what's different
Duct Repair & Sealing in Houston is shaped by local conditions. Humidity and mold: Oversized systems and leaky attic ducts leave homes clammy and promote mold on registers and in air handlers.
Slab-on-grade homes with attic ductwork are typical, and many two-story homes run two systems. Older homes inside the 610 Loop may have pier-and-beam foundations with ducts under the floor. Aging R-22 equipment is still common in 1980s and 1990s neighborhoods. For duct Repair & Sealing, that means the contractor should start with inspect and test and confirm what is actually installed before quoting. Another local pattern worth mentioning to the tech: clogged condensate drains. Houston air conditioners pull a lot of water from the air, so algae-clogged drains and tripped float switches are frequent calls.
Inside city limits, mechanical permits come from the City of Houston; suburbs like Pasadena, Sugar Land and Pearland run their own permit offices. The best time to schedule AC maintenance is February through April, before the first stretch of 90°F humid days. Replacement work booked in fall or winter usually means shorter waits than in July.
Houston climate
Summers are long, hot and muggy, with high dew points from May through October. Winters are short and mild, though occasional hard freezes stress heat pumps. Hurricanes and tropical storms bring flooding and power outages.
