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.
Duct Cleaning and Mold Treatment
Over the years, ducts collect dust, pet dander, pollen, and construction debris. Our HEPA vacuum duct cleaning pulls that buildup out so it isn't blown back through your home, and clearing it can help air move more freely. Where mold or mildew is a concern, we offer an antimicrobial fogging treatment for the duct system.

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.
