Signs You Need Air Duct Sealing in Lewisville, Texas
Leaking ducts often reveal themselves through subtle changes long before they become major problems. Spotting early signs like uneven temperatures, rising energy bills, or dusty rooms helps you address airflow loss quickly and protect both your comfort and your HVAC system’s efficiency.
Hot and Cold Spots Throughout Your Home
Uneven temperatures from room to room often signal air loss within your ductwork. Leaks allow conditioned air to escape before reaching its destination, reducing comfort. We inspect and seal problem areas to restore balanced airflow.
Unexpectedly High Energy Bills
When ducts leak, your HVAC system must work harder and run longer to maintain indoor temperatures. This wasted energy drives up utility costs. We seal air gaps to improve efficiency and help lower monthly energy bills.
More Dust in the Air or on Surfaces
Excess dust around vents or on furniture may mean your ducts are pulling debris from unconditioned spaces. Sealing leaks prevents contaminants from entering the system, helping your home maintain cleaner, healthier indoor air.
Weak Airflow at Certain Vents
If airflow feels weak at specific vents, duct leaks may be diverting air before it reaches the room. Our technicians locate the source of loss and seal affected sections to restore proper circulation and comfort.
We Seal, Strengthen, and Protect All Residential Duct Systems in Lewisville, TX
Healthy airflow begins with tight, well-sealed ducts. Kelly’s Heating and Air has helped Lewisville families enjoy cleaner, more efficient comfort for generations by sealing leaks, reinforcing worn connections, and restoring performance across every type of residential duct system. Our trained duct specialists make sure your home receives steady, dependable airflow through every season.
Flexible Duct Systems
Flexible ducts are common in Lewisville attics and can loosen or sag over time. When collars shift or insulation compresses, air escapes before reaching living spaces. We seal flex-duct joints, secure loose fittings, and check for crushed sections so your system delivers smooth, consistent airflow from room to room.
Sheet Metal Duct Systems
Sheet metal ducts last for decades but often develop leaks around seams or older connections. Our team applies high-grade sealants and performs careful pressurization checks to secure each seam and eliminate escaping air. This strengthens system performance, reduces energy loss, and brings more even temperatures throughout your home.
Duct Board Systems
Duct board provides strong insulation yet can separate at panel joints or develop small gaps that pull in attic dust. We seal duct board systems using HVAC-approved mastic, reinforce weakened edges, and restore proper airflow so your family receives cleaner, conditioned air during every season.
Return-Air Duct Systems
Return ducts often develop leaks that draw in dust, insulation fibers, and outdoor allergens. Our team seals return boxes, boot connections, and key pathways to prevent contaminants from entering your system. Clean, sealed returns help your HVAC breathe easier and support healthier indoor air for your home.
Multi-Zone Duct Systems
Zoned homes depend on multiple branch ducts that must be tightly sealed to deliver balanced airflow. Our technicians inspect each zone, check damper housings, and seal smaller runs to ensure every space receives the airflow intended. Proper sealing reduces uneven rooms and helps your system operate with less strain.
Transitions and Plenum Chambers
Transitions and plenums often develop gaps from vibration, aging tape, or shifting ductwork. We seal connection points, secure metal joints, and restore airtight performance where airflow is strongest. A well-sealed plenum helps your HVAC move clean, conditioned air efficiently to every room.
