Trusted Across the Kansas City Metro

Most homeowners don’t realize that their air ducts leak air — sometimes 20% to 40% of heated or cooled air never even reaches the rooms in the house. Those leaks waste money, strain your HVAC system, and make certain rooms hard to keep comfortable.

At Precise Duct Cleaning, we specialize in air duct sealing for homes in Lee’s Summit, MO and within 30 miles across the Kansas City metro. Whether your ducts are in the attic, crawlspace, or basement, we can seal the leaks so your system runs more efficiently, your home feels more even in temperature, and your energy bills drop.

What Is Air Duct Sealing?

Air duct sealing is the process of finding and closing leaks in your ductwork so air stays inside the system and goes where it’s supposed to.

Leaks often happen at:

  • Duct joints and connections
  • Around vents and registers
  • In flexible ducts in attics and crawlspaces
  • At the furnace plenum

We use professional-grade sealants and methods (not duct tape!) to make your system airtight. The result is better comfort, better air quality, and lower energy costs.

Signs Your Home Needs Duct Sealing

Many families in Lee’s Summit, Blue Springs, Independence, Raytown, and Overland Park don’t realize their ductwork is leaking until they see the signs:

  • Uneven temperatures – some rooms are too hot, others too cold.
  • High utility bills – especially in summer and winter.
  • Dusty home – leaks pull in dust from attics, crawlspaces, and basements.
  • Noisy HVAC system – blowing harder to make up for lost air.
  • Weak airflow – certain vents barely blow.

If you’ve noticed these issues, duct sealing may solve them.

Benefits of Professional Air Duct Sealing

Lower Energy Bills

The U.S. Department of Energy estimates the average home loses 20–30% of conditioned air through leaks. Sealing ducts keeps air inside and lowers monthly bills.

More Comfortable Rooms

No more hot upstairs bedrooms in Overland Park or cold basements in Independence. Sealed ducts balance airflow throughout the house.

Longer HVAC Life

When air stays inside the ducts, your system doesn’t have to run as long or as hard, reducing wear and tear.

Cleaner Indoor Air

Sealing prevents dust, insulation fibers, and even pests from being pulled into ducts through leaks in crawlspaces or attics.
