Frequently Asked Questions About Green Seal Energy

Absolutely! Inconsistent heating and cooling is a common result of leaky ducts and Green Seal Energy’s top-notch duct sealing services will solve that issue. Once we seal your ducts, conditioned air will stay where you want it and there will be no more hot and cold rooms.

Yes! While allowing conditioned air to escape, leaky air ducts pull in dust, mold, and debris from outside and circulate these contaminants throughout the property. Sealing your ducts will boost the air-tightness of your home or office by up to 90% while eliminating dust accumulations.

Independent studies show that duct sealing at your property can save up to $850 per year! Most homeowners save at least 20%, and others enjoy savings of up to 40% of their total bill. Exact totals vary becuse of property location, square footage, and HVAC unit SEER rating.

By looking for leaks, we can calculate how much cold and hot air you is being lost via your attic, crawlspace, garage, basement, windows, and other unwanted places. Our initial test shows how much good air you are losing through leaky ducts and vents and we formulate a plan to change that.

Absolutely! Our formula is made from a water-soluble organic compound and is frequently used to sterilize hospitals, surgery centers, and schools. You can remain in your home or office while the technicians work. But we recommend that pregnant women and senior citizens avoid exposure.

No! Our organic sealant is safe to breathe. Lab tests show only a low level of VOCs and its odor goes away within a few hours.

Holes larger than 5/8 of an inch in diameter are too big for the sealant to bond effectively. Larger holes must be repaired by hand before the sealant is applied.

Some sealant will inevitably leak into the attic, garage, or wall cavities. But it will dry quickly and will be harmless in those areas. By filtering the air during our sealing process, we make sure that none of our sealant vapors escape into living areas or office areas.

No. Our crews will protect all HVAC components and electronic devices before sealing. Humidifiers or UV lights may need to be covered or removed and then re-installed as a precaution. We recommend covering high-end electronics equipment and items located close to air returns or registers. Our crew will cover any furniture.

The typical drying time is two hours, depending on how much ductwork you have and how many leaks you have.

We guarantee our sealant will work for at least 10 years. It has been stress-tested and shown to last up to 40 years in homes. We expect your heating and cooling systems to work efficiently for as long as you own your home.

It is not a requirement, but any extremely dirty ducts should be cleaned first. Our technician will address this during the initial inspection and recommend a cleaning if needed.

Yes. Ducts from all types of materials can be successfully cleaned after being sealed. Our formula dries into a durable substance that remains flexible and pliable.

No. Our formula doesn’t coat or line your ducts. The only visible sealant remaining will cover the leak that was sealed.

No. Sealing ducts will have no impact on any noises coming from your HVAC unit. Such noise typically is caused by one of two things: The ductwork is too small for the size of the HVAC unit that is installed, or the airflow through the indoor coil of your system is restricted. A certified contractor can help with either issue.

That depends on additional factors. Condensation on crawl space ducts typically stems from an inadequate vapor barrier. While sealing the crawlspace is recommended, you might need to add a free-standing dehumidifier or rely on an application of Aeroseal. If left untreated, crawl space condensation will degrade the insulation’s R-value.

Probably not. Water getting into your in-slab ductwork is typically a sign of a larger drainage issue with your home or office. Sealing your ducts typically will not remedy that problem. We recommend that you have a licensed contractor review your drainage situation.

Aeroseal duct sealing is the process of sealing leaks, cracks, and gaps in your home or building’s air duct system to improve energy efficiency, airflow, and indoor air quality.

Leaky ducts can lead to energy loss, uneven heating and cooling, higher utility bills, and poor air quality. Sealing them improves HVAC performance and saves money.

Common signs include inconsistent temperatures, high energy bills, excessive dust, and poor airflow from vents.

Ducts can be sealed with aerosol duct sealing patented technology which seals leaks from the inside.

Homeowners can save up to 20–30% on heating and cooling costs by properly sealing and insulating ductwork.

Not at all. Especially with aerosol methods, the process is clean and non-invasive, typically requiring only access to the ducts near your HVAC unit.

Most residential projects can be completed in 4 to 6 hours, depending on the size and condition of the duct system.

Yes, it is completely safe. The materials used are non-toxic and certified for use in residential and commercial applications.  Even the Mayo Clinic has had their ducts sealed.

Yes, by reducing the amount of dust, pollen, mold, and contaminants entering your ducts, aeroseal duct sealing can significantly improve indoor air quality.

When done professionally, duct sealing can last up to 40 years. Aeroseal sealants are guaranteed to last at least 10 years.

No. Duct cleaning removes dust and debris, while duct sealing focuses on stopping air leaks to improve system performance.

While some visible gaps can be sealed manually, professional sealing is required for comprehensive results and to access duct work running through the walls.

Prices vary by home size and method used, but typical residential sealing ranges from $1500 to $3,500. Rebates or energy incentives may also be available.

Yes, sealing leaks can reduce whistling, rattling, or other noises caused by escaping air.

Absolutely. The energy savings, improved comfort, and air quality benefits often pay for the service within a few years.

Yes. It can almost double the efficiency of your system. By reducing strain on your HVAC system, sealed ducts help prevent premature wear and extend the life of your equipment.

Definitely. You’ll notice more consistent temperatures and better airflow in every room. Also, helping you breath healthier cleaner air.

Yes. Sealed ducts prevent moist air from entering or exiting, helping to regulate indoor humidity levels more effectively.

Even with a new system, leaky ducts can waste energy. Sealing ensures your system operates efficiently from the start. With out sealing your ducts you lose half of the efficiency of the new system.

Yes. Leaky ducts can throw off your home’s air pressure balance, leading to drafts and reduced HVAC efficiency.

Technicians use pressure tests, thermal imaging, or smoke tests to pinpoint leaks before sealing.

It’s a high-tech method where sealant particles are blown into the duct system and accumulate at leak points from the inside out. Kind of like a fix a flat in a cars tires.

Yes. By improving HVAC efficiency, your system uses 25%-35% less energy, which means fewer greenhouse gas emissions.

Even new homes have poorly sealed ducts. The method for installing ducts has not changed in over 100 years.

Yes. Ducts located in unconditioned spaces like attics and crawlspaces are more prone to leaks and energy loss. Anytime any one enters these spaces they have the potential to dislodge or disconnect duct work. In many cases home owners are just heating and cooling the attic unknowingly.

Yes, there are Federal Tax Credits of 30% and Evergy has some energy rebates for energy-efficient home upgrades, including duct sealing in some areas.

Indirectly, yes. Sealed ducts can help reduce the transmission of outside sounds through your HVAC system.

It will improve airflow, making it more balanced and consistent throughout the home. Usually, many other issue are found in the process of sealing the ducts that are resolved.

Common materials include Aeroseal Duct Sealants and some foil tape for any hole over ⅝ of an inch.

Leaky ducts don’t typically affect standalone appliances directly, but poor air circulation from HVAC can influence overall home ventilation.

Residential duct sealing involves locating and closing leaks in the ductwork of a home’s HVAC system to improve comfort, efficiency, and indoor air quality.

Leaks can occur due to poor installation, aging materials, vibration from HVAC use, or damage from pests and construction over time.

Up to 25–35% of conditioned air can be lost through leaky ducts in typical homes, resulting in energy waste and uneven temperatures. Usually adding up to a 4×4 foot hole of total leakage.

Yes, properly sealed ductwork can significantly reduce your heating and cooling costs. Usually, by 20%-35%.

Most ductwork is hidden behind walls, ceilings, or in attics and crawlspaces, so professional equipment is often needed to detect leaks. We do a duct leakage test and send fog through the home and many leaks can be identified that way.

They may use blower doors, pressure testing, thermal imaging, or even specialized fog machines to locate hidden leaks.

Yes. Sealing helps distribute air more evenly, eliminating hot or cold rooms.

No. Most sealing processes are minimally invasive and completed in just a few hours without damage to walls or ceilings.

You can seal your ducts first or after the new system is installed. If you have an option, do it afterwards to make sure all the new duct work is sealed.

Small visible gaps may be DIY-friendly with foil tape or mastic, but a full system seal is only possible with Aeroseal technology.

Resealing is typically not ever needed, unless ducts are modified or damaged.

Yes. Properly sealed ducts help prevent dust, insulation particles, and allergens from entering the airflow and circulating indoors. Most dust is sucked in from the attic or basement.

Absolutely. It helps keep contaminants like mold, pollen, and fumes from entering your system and recirculating. More of the air in your home gets circulated and filtered.

Certified Aeroseal Technicians using certified Aeroseal equipment. Avoid companies that claim they can provide the same results with manual sealing.

Yes. Even smaller homes can benefit greatly from improved comfort, efficiency, and reduced energy bills with proper duct sealing.
