Thomas and his assistant arrived on time for the appointment to check and prepare our heating and cooling system for the summer season. They changed a major filter and took pictures of and readings on both the furnace and the air conditioner. They were efficient, proficient, and professional.

How Air Duct Sealing Works

Air duct sealing closes the gaps, loose joints, and cracks where conditioned air escapes from your ductwork. Over time, seams separate, connections loosen, and tape dries out, and each of those spots lets air slip away before it reaches a vent.

Sealing starts with finding the leaks. Once we know where the ductwork is losing air, we seal the joints and seams so air stays in the system and travels where it was meant to go. If a section is crushed, disconnected, or too damaged to seal, we will tell you plainly and explain what it would take to repair it.

Kaw Valley Heating & Cooling has worked on the heating and cooling systems in Topeka homes since 1979. Duct sealing is one of the most practical fixes we offer, because it makes the equipment you already own work better.

Clues Your Ductwork Is Leaking Air

Leaky ducts rarely announce themselves directly. These signs usually point to the problem.

  • Rooms that never feel comfortable
  • High bills despite a newer system
  • Dusty rooms soon after cleaning
  • Weak airflow at some vents
  • Hot or cold spots upstairs

If several of these sound familiar, the ducts are worth a closer look. Call the office to set up an inspection.

What Leaky Ducts Cost You in Comfort and Energy

Leaky ducts cost you money because you are paying to heat and cool air that never reaches your living space. That air ends up in the attic, crawl space, or inside the walls while the system runs longer to make up the difference. Comfort suffers too. Rooms at the far end of a leaky duct run get less air than the rooms closest to the furnace, which is why one bedroom stays cold in January while the living room is warm.

Leaks can also pull air in. A leaky return duct can draw dust, insulation fibers, and stale air from unfinished spaces and send it through your home. In a Kansas summer, that can mean hot, humid attic air mixing into the air your system is trying to cool.

What You Gain From Sealing Your Ductwork

Sealing your ductwork puts more of your heating and cooling where it belongs. Rooms that used to lag behind get their share of air, and the whole house feels more even.

Your system gets a break as well. When less air is lost along the way, your furnace and air conditioner reach the thermostat setting sooner and run less, which is easier on the equipment and on your energy bills.

Sealed ducts also help indoor air quality. Closing the leaks keeps dusty air from unfinished spaces out of the system, and it pairs well with air duct cleaning when the ducts are dirty as well as leaky.

Our Step-by-Step Duct Sealing Process

Every air duct sealing job follows the same clear steps.

  1. Inspection. We examine your ductwork and system to find where air is escaping.
  2. Price before work. You get the scope and the price before any sealing starts.
  3. Sealing. We seal the leaking joints, seams, and connections we found.
  4. Final check. We run the system and confirm airflow is reaching your vents.

Our technicians are background-checked and NATE certified, so the people working in your home have been vetted and trained. Call the office or fill out the form to book your duct sealing inspection.

What Duct Sealing Costs

The cost of air duct sealing depends on the size of your home, how much ductwork there is, how accessible it is, and how many leaks we find. Ducts in an open basement and ducts buried in a tight attic are different jobs, so we give you the price after the inspection.

Sealing is usually far less disruptive than replacing ductwork, since it works with the ducts you already have. When replacement would serve you better, we price both options so you can compare them side by side.

We will not recommend sealing that you do not need. For larger projects, financing is available through Hearth, and first responders and military members get 10% off.
