Ductwork Inspection, Repair & Sealing for Homes Throughout Sunnyvale
Leaky, disconnected, or poorly sealed ductwork can quietly waste a significant amount of your system's heating and cooling before it ever reaches your living space. If some rooms in your home never feel quite right, your ductwork may be part of the reason.
We inspect accessible ductwork for leaks, damage, and poor connections, then explain what we find and what repair or sealing options make sense for your home.
Ductwork problems are easy to overlook because they don't announce themselves the way a broken compressor does. Instead, they show up gradually as higher bills, uneven rooms, or a system that seems to run constantly without ever quite keeping up, which is why we treat duct inspection as part of any broader comfort diagnostic.
Sunnyvale, home to its own small Sunnyvale ISD, keeps a semi-rural feel between Mesquite and Garland, with larger lots and many custom homes. Those homes often have more than one system, and bigger attics to go with them.
Long duct runs through a hot attic can lose a lot of cooling before the air reaches the far rooms. If one end of your home is always warmer, that's one of the first things we'd want to look at.

How do I know if my ductwork has a problem?+
Common signs include rooms that are always hotter or colder than the rest of the house, unusually high energy bills, or noticeable dust buildup. An inspection can confirm what's actually happening.
Is duct sealing worth it?+
For homes with noticeable leaks, sealing can meaningfully improve comfort and reduce wasted conditioned air. We'll let you know if it's likely to make a real difference in your home specifically.
Can I seal ductwork myself with tape from the hardware store?+
Standard duct tape actually performs poorly over time despite the name. Proper sealing uses mastic sealant or foil tape rated for HVAC use, and accessing and identifying every leak point often requires getting into attics or crawlspaces most homeowners don't regularly enter.
How long does duct sealing take?+
It depends on the extent of the ductwork and how many leaks we find, but most residential duct sealing is completed in a single visit.
How much does duct sealing or repair cost?+
It depends on how many leaks or damaged sections we find and how accessible the ductwork is. We'll give you a clear price after the inspection, before any sealing or repair work begins.
