Duct Sealing & Replacement

Duct Sealing and Replacement are vital to home comfort

GreenHomes America quality contractors offer expertise in duct sealing your home's ductwork and optimizing  air flow.

Homes with a forced air furnace or central air conditioner contain ductwork that carries the warm and cool air your equipment creates into different rooms in the house. Additionally, ducts are typically sheet metal or flexible in nature.

Homes with flexible ducts over 10 - 15 years old most likely require duct replacement work. Why? Generally, older flexible ducts offer very poor insulation. Additionally, older flexible ducts may contain asbestos as the insulation material. Plus, these duct likely obtained rips and tears over the years.

Also, during installation, many contractors do not properly follow duct sealing best practices. As a result, many improperly installed ducts leak air. Improper duct sealing means cooled or heated air flows into attics, basements and walls. This is not what you want!

  • R-8 insulation is best; go no lower than R-6.
  • Ensure there is a 3-step, UL 181 approved duct sealing process.
  • Anti-microbial lining ensures contaminants don't adhere to the duct lining.
  • Insist upon dense weave/heat resistant jackets.
  • Ask about balancing dampers if you have rooms that are far apart.

Ductwork must be well-sealed, insulated, and balanced. This helps ensure your home's heating and cooling systems work as efficiently as possible. However, most homes contain leaky ductwork and insufficient air flow, which results in an uncomfortable living environment — regardless of the thermostat setting.

A properly sealed duct system makes your home more comfortable, energy efficient, and delivers cleaner air.

Replacing or making improvements to your duct system can:

Improve Comfort

Duct sealing and insulation help with common comfort problems, such as rooms that are too hot in the summer or too cold in the winter.

Enhance Indoor Air Quality

Fumes from household and garden chemicals, insulation particles, and dust enter your duct system. As a result, these particles aggravate asthma and/or enhance allergy problems. Therefore, duct sealing improves indoor air quality by reducing the risk of pollutants entering ducts and circulating through your home.

Promote Safety

During normal operation, gas appliances such as water heaters, clothes dryers, and furnaces release combustion gases (like carbon monoxide) through their venting systems. Leaky ductwork in your heating and cooling system creates back-drafting, where these gases are drawn back into the living space, rather than expelled to the outdoors. Sealing leaks reduces this risk.

Save Money

Leaky ducts reduces heating and cooling system efficiency by as much as 20%. Plus, duct sealing and insulation increases efficiency, lowers energy bills, and frequently pays for itself in energy savings. Additionally, for any homeowners planning to install new heating and cooling equipment, a well-designed and sealed duct system allows you to downsize to a smaller, less costly heating and cooling system. And, this system typically provides better dehumidification.

They also insulate ductwork in attics and crawl spaces, which provides maximum comfort.
