An air duct leak creates an extremely vulnerable spot in your home or commercial HVAC system. It can make your space extremely uncomfortable and your AC may not run efficiently. Improperly sealed air ducts can also strain your air conditioning system and accelerate wear and tear, leading to costly repairs and replacements.

You could be losing up to 30% of heated or cooled air in your system through holes, cracks, loose connections in ductwork, poorly designed ducts, and inadequate insulation. Fortunately, NexGen provides air duct sealing to minimize air loss and ensure your HVAC system is reliable and efficient.

Signs That You Require Duct Sealing

In the vast majority of homes, ductwork is installed behind walls, in the ceiling, and under the floor. But there are a few signs of leaks in your duct system, such as:
  • Decreased Heating or Cooling Performance: If one room or area isn’t getting enough hot or cold air, the ductwork serving that location may have a large hole or leak, or it may have collapsed.
  • Higher Utility Bills: An increase in home energy usage and a higher monthly utility bill can mean your heating and cooling system is working harder to compensate for a significant loss of air.
  • Loud Noise: Leaky ducts tend to make noise such as whistling, flapping, rattling, hissing, and rumbling. If you hear any of these sounds, contact NexGen for a ductwork inspection.

Benefits of Duct Sealing

Duct sealing can have numerous benefits. Once your ductwork is properly sealed, there should be an immediate decrease in energy usage as more of the heated or cooled air produced by your HVAC will reach every room. Repairing holes and leaks prevents contaminants from entering ductwork and polluting your indoor air. This includes dust, pollen, mold, rodents, and insects. A damaged duct, depending on its location, can cause garbage odors; duct sealing can stop this from happening. Your home will also be more comfortable as cooled or heated air will be more evenly distributed.

Why Professional Duct Sealing Is Important

When it’s time for air duct sealing, a professional touch is extremely important. An expert in duct sealing uses the proper materials and techniques to ensure your ductwork is adequately sealed. The latest tools are used to test for air loss and find exactly where leaks are. We can address any type of leakage to restore energy efficiency and performance. With professional sealing, short-term and long-term savings can be realized because we aim for the lowest air loss rate that can be achieved with your system.

Amazing Reviews From Our Loved Clients

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.

Yesterday I had NexGen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, NexGen’s price was over $3,000 cheaper than all other competitors.

My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend NexGen.
