Duct Sealing - Serving Greater Omaha and Western Iowa

 

Are Leaking Ducts Costing You More Than You Think?

You can see a water leak, but an air leak is invisible. Duct leaks can be difficult and costly to find with ductwork hidden between the walls, floors, and ceilings of any residential home. The older, traditional use of mastic (a messy caulk-like substance) or taping of leaks not only is less effective than Aeroseal, but also can be very labor-intensive, expensive and can only be applied to ducts with physical access. Other substances break down over time, but the Aeroseal sealant does not and even has a 10 year warranty to back it up.

 

Do-it-yourselfers might attempt their own fixes, but what about those ducts you can’t see or access? Let McCarthy's One Hour Heating and Air Conditioning handle the entire job and you won’t be tearing up your home or worried about incomplete seals. With Aeroseal technology, we can pinpoint and cover leaks in roughly an hour, from the inside out with a success rate of up to 98%. Aeroseal is the most effective, affordable, and viable method of sealing air duct leaks on the market.

 

Aeroseal can reduce duct leakage by up to 90%, reduce your energy use by up to 30%. Aeroseal has also been shown to dramatically improve comfort and homeowner satisfaction with their heating and cooling systems.

 

Did you know?

  • Nearly 50% of your home’s energy bill is spent on heating, air conditioning and ventilation.
  • Duct leakage in residential homes costs consumers $25 billion each year.
  • On average, 30 cents of every $1 you spend on heating and cooling your home disappears into thin air due to leaky ducts. Leaky ducts pull mold, dust and other pollutants into your home, presenting indoor air quality issues and creating and/or aggravating allergy problems.
  • Leaky ducts contribute to safety issues in residential homes relating to back drafting of gas appliance fumes, auto exhaust and radon gas into your living space.
  •  

    Leaky ducts in a residential home contribute to:

  • Loss of cool and warm conditioned air to the outside or unconditioned spaces of your home resulting in higher energy bills
  • Even the most energy-efficient heating and cooling systems not performing at its best
  • Forcing your system to work harder and wear out sooner, costing you more money
  • Excess humidity levels that can lead to costly home repairs
  • Hard to heat or cool rooms leading to discomfort
  • Musty odors and other indoor air quality (IAQ) issues
  •  

    What are the benefits?

  • Savings: The money formerly leaking out of your ducts will stay in your pocket longer
  • Comfort: Your hard to heat or cool rooms will have more even temperatures and be more comfortable
  • Improved air quality: You will see a reduction in dust, humidity, fumes and other odors
  • No hidden leaks: Seals leaks nearly impossible to reach using other methods
  • Environmental Friendly: A reduction of the amount of air pollution created from generating less energy
  • Solve your air flow and ventilation problems by having the experts at McCarthy's Heating and Air Conditioning come out and evaluate your home.

    The Leaky Duct Solution

  • High energy bills?
  • Uncomfortable hot or cold room?
  • Excessive humidity?
  • Excessive dust?
  • Musty odor or fume smells?
  • If so, you probably have leaky air ducts. But don't worry, there’s a solution.  Aeroseal Duct Sealing is a patented, breakthrough technology that tackles leaks from the inside out. It was developed in 1990 at U.C. Berkeley with funding from the United states Department of Energy, Environmental Protection Agency, California Institute for Energy Efficiency, and Electric Power Research Institute. Additionally, the Department of Energy declared Aeroseal as one of the most beneficial energy technologies for American consumers.

     

    About Aeroseal Ductwork Sealing Technology

    Aeroseal's aerosol ductwork sealing technology was invented and developed by the Energy Performance of Buildings Group at Lawrence Berkeley National Laboratory in 1994. This technology internally seals duct leaks in air distribution ducts by injecting a fog of aerosolized sealant particles into a pressurized duct system. The key to the technology is to keep the particles suspended within the air stream without depositing on the duct surfaces until they reach the leaks, where they leave the air stream, deposit at the leak edges, and seal the leaks.

    Aeroseal Frequently Asked Questions

    The Aeroseal process won the "Best of What's New" award from Popular Science magazine, and the "Energy 100" award from the Department of Energy (DOE). The DOE also rated the Aeroseal duct sealing process as one of the 23 most beneficial technologies available to American consumers that has come out since the agency was created.
    Aeroseal provides a 10-year warranty on the seals created with our process. We have enormous confidence in the quality of our seals since they are based on Lawrence Berkeley National Laboratory research and a patent through the University of California. The EPA has endorsed Aeroseal, as have numerous local energy utilities. Note: the warranty is for on-site seal failures and does not cover additional damage (e.g. an electrician that steps on a duct while running wiring), wear or tear (i.e. the shelf life of a plastic duct is passed, rodents eat into a duct, or a duct rusts out), and subsequent replacement of failed ducting. In more than 85,000 seals done, McCarthy's Heating and Air Conditioning has received very few warranty claims.
    Ductwork runs through attics, crawlspaces, basements, garages, and walls. Leaking return air ducts pull in dust and other indoor air pollutants and sends them to the central heating and cooling system. From there, they are sent to the living areas of your home. The Aeroseal air duct sealing system can reduce the amount of leakage by as much as 90%, reducing dust and other indoor air pollutants from the conditioned air in your home.
    This noise is usually the result of two conditions. One is created when the ductwork is undersized and air is rushing through your air duct system. The other condition is caused when a limited amount of air is allowed to flow through the indoor coil of your heating and cooling system. Once the exact problem has been identified, your contractor can provide the best solution for noise reduction.
    Some homeowners have saved up to 40% of their energy bills after having the Aeroseal air duct sealing system seal their central air duct system. A typical homeowner should expect to see measurable reduction in energy use for heating and cooling.
    The Aeroseal air duct sealing system can help improve the comfort of your home by reducing the difference in temperature levels throughout your home.
    The Aeroseal air duct sealing process leaves no lingering odor, and since the material does not put off gas over time, there will be no odor for the life of the product.
    The sealant material consists of a water-based solution (65% water) prior to application. The dried sealant material primarily contains two chemicals, vinyl acetate polymer (VAP) and 2- ethyl-1 hexanol (2E1H). The vast majority of what is left in the duct system is VAP, which has been used in water-based paints, adhesives, and hair spray. VAP has been used in chewing gum, and has no OSHA Exposure Limit. 2E1H is a common industrial solvent and is not considered toxic by OSHA. A review of the literature showed no ill effects after long-term exposure to concentrations of 200 ppm. The largest concentration of 2E1H measured in test houses was 1 ppb (200,000 times smaller), during Aeroseal injection. The sealant is UL-listed for smoke generation and flame spread (UL 723 0,0), and additional testing by UL showed no signs of mold growth or erosion.
    The sealant only sticks to the holes in the air duct without coating the rest of the duct.
    It's likely that the holes and cracks in the ductwork have allowed dust and other particulate matter to enter the system. If you are experiencing extensive levels of household dust, this might be the reason. In most instances, duct cleaning is not found to be required prior to Aeroseal sealing. Your Aeroseal contractor can advise whether it will be necessary to clean your ductwork prior to sealing.
    The sealing material has been found in rigorous testing to last over 10 years without failure.
    The vinyl sealing material remains rubbery, never cracking.
    The pre-seal is done to measure the leakage as a baseline for the progress. We block off the registers with foam or plastic and inject an UL tested and approved aerosol into the duct system. Since the air has no place to go except out through the leaks (the registers are blocked), the sealant material is deposited precisely at the air duct holes or cracks where leakage occurs. A computer and sensors are used to measure and control the progress. The technology is patented from the University of California and the process is endorsed by the Environmental Protection Agency. The post-seal test is then done to measure improvements. A complete report and certificate will be printed on the spot to provide a record of improvements done.
    A series of government reports have shown that air duct sealing can lead to up to $850 in energy savings per year. Some homeowners have saved up to 40% on their energy bill. Naturally, exact savings are difficult to precisely estimate since they depend on a multitude of variables such as your weather, house condition and design, your heating and air conditioning system, system usage – as well as other factors like energy prices. Also, all Aeroseal air duct certified technicians are qualified to run a program made by the Environmental Protection Agency (EPA) called “Duct Investor”. Duct Investor takes a comprehensive list of variables and provides a homeowner with the best available estimate of what they should realize in cost savings.
    Inspection discovers any obvious break in the duct work and, as the initial step of the sealing process, the Aeroseal system will establish an exact amount of leakage in the duct system. Of course, many people already know that a room or two in their house doesn’t get good air circulation because they can feel it. Or, they already know that their energy bill is high because they see it. The diagnostic measurement, provides a scientifically valid means to understand the performance of your air duct system. Many people are surprised to learn that homes typically leak 30% to 40% or more of their air through air duct leaks.
    Holes and cracks up to 5/8th of an inch wide can be completely sealed.
