FAQ

Air Duct Cleaning

What is air duct cleaning?

Professional air duct cleaning is used to remove any build up within your ductwork. Over time, ducts can collect dust, carcinogens, and mold.

During our thorough cleanings, all ductwork passageways will be inspected and sanitized.  To clean the supply, intake, and return ducts throughout your home, we use specialized blowers, vacuums, and brushes. We then clean any air handlers, registers, grilles, fans, motors, and coils in your HVAC system.

When should you have your air ducts cleaned?

NADCA says homeowners should clean air ducts under these circumstances:

  • Every three to five years.
  • When you move into a new home, unless you know the previous homeowner serviced the air ducts within the last three years.
  • After building a new home. It’s likely the ducts have built up debris from drywall dust and other materials used during the construction phase.
  • After completing a home remodeling project. Construction projects spread sawdust throughout the home, and unless you go to lengths to protect the ducts, the dust will extend into the ductwork.
  • If you have pets in the home that shed fur and dander. Duct cleaning and effective home cleaning practices can help to prevent it from spreading throughout the home.

How often should air ducts be cleaned?

We suggest having your home’s air ducts cleaned every three to five years, however, homeowners with children, pets, respiratory issues, or a compromised immune system may want to have their ducts cleaned more often. A good filtration system will reduce the cleaning frequency.

How long does duct cleaning take?

Typically, it will take two to four hours to clean the air ducts in a single family home.  Older homes and those with pets may take longer.  Newer homes, townhomes, and condos may take less time.

Will the duct cleaning make a mess in my home?

No. We use the highest quality and most state of the art duct cleaning equipment which ensures no mess is left behind once the duct cleaning service is complete.

Are any chemicals used?

No. Chemicals are not used unless required by an industrial hygienist or a certified restoration contractor. In the event chemicals are required to perform a project Aeroseal Colorado will only use an EPA registered anti-microbial solution.

Will duct cleaning reduce my energy bills?

By investing in a professional air duct cleaning, your system may be more efficient and less likely to break down, saving you money on your energy bills and repair costs.

Is air duct cleaning necessary?

Air duct cleaning ensures the air you breathe is clean and properly filtered.  Ductwork cleaning removes any contaminants from the pipes including: dust, pollen, bacteria, and mold.  Without quality duct cleaning service, you and your family are at a higher risk of breathing polluted air.  Keep your family healthy by scheduling duct cleaning service.

Dryer Vent Cleaning

What is a professional dryer vent cleaning?

A dryer vent cleaning involves removing lint and dust buildup from the dryer and its vents.  This ensures moisture is not being held in the dryer vent and reduces the risk of an electrical fire.  A professional dryer vent cleaning will also increase the energy efficiency of your dryer, enables it to dry clothes faster using less energy.

How often should your dryer vent system be cleaned?

We recommend having your dryer vents cleaned once every two years. There are a couple of factors to consider: the age of the dryer and how often the dryer is used.  If the dryer is 10 years or older, the vents may need to be cleaned more often.  Dryers that get frequent use should also be checked more often.

How are dryer vents cleaned?

Dryer vents are cleaned with a brush and a vacuum system that runs through the entire length of the vent.  This ensures all lint is removed from the vent walls.

How long does a dryer vent cleaning take?

A professional dryer vent cleaning usually takes about an hour.

Aeroseal Duct Sealing

How does the Aeroseal air duct seal work?

In a nutshell, the Aeroseal process:

  • Measures existing leakage with a pre-seal test that creates a baseline for evaluating progress
  • Blocks off all registers with foam or plastic plugs
  • Injects an UL-tested and approved aerosolized sealant spray into the duct system
  • Forces the sealant spray toward the leaks, where it is deposited at holes, cracks and gaps where leakage occurs, sealing the leaks
  • Measures and controls the progress uses computer and sensor technology that’s patented from the University of California and endorsed by the Environmental Protection Agency
  • Measures improvements through a post-seal test
  • Provides progress report and prints a certificate that provides a record of improvements

How much can I save with Aeroseal duct sealing?

Multiple government reports have shown that air duct sealing can save up to $850 in energy costs each year; some homeowners have seen their energy bills drop by up to 40%. Aeroseal’s certified technicians are qualified to provide Duct Investor, a tool designed by the Environmental Protection Agency. Duct Investor collects comprehensive list of variables and data and provides a homeowner with the best available estimate of what they should realize in cost savings.

Exact results vary based on variables such as the climate, house condition and design, heating and air conditioning systems, utility rates, HVAC system usage and other factors such as energy prices.

What size of holes can be sealed using the Aeroseal air duct sealing process?

The Aeroseal process completely seals holes, cracks and leaks up to 5/8th-inch wide.

What will the air duct diagnosis and inspection tell me?

Most people are surprised to learn that their air systems typically leak from 30 to 40% — or even more – of conditioned air through tiny holes, cracks or gaps in the system. Aeroseal’s diagnosis and inspection process identifies breaks in the ductworks and measures the exact amount of leakage. While many homeowners already know there’s a problem — a room or two has poor air circulation or energy bills are excessive — the diagnostic process provides scientific evidence that helps you understand air duct performance.

Does the air duct sealant become brittle?

No — the polymer sealing material remains rubbery and crack-free.

How long will the air duct sealant last?

Rigorous testing has shown that the sealant lasts over 10 years without failure – and comes with a 10-year warranty to back it up.

Do air ducts require cleaning before Aeroseal sealing?

In most cases, duct cleaning isn’t necessary. Ductwork holes, cracks and leaks may have allowed dust and other particulate matter into the air duct system; if you’re experiencing excessive household dust, duct leaks are probably to blame. Your Aeroseal contractor will advise whether ductwork cleaning is required before sealing.

Does the sealant coat the inside of the air ducts?

No — the sealant only accumulates at the edges of holes in the air duct, sealing leaks without coating the rest of the duct.

Is the sealing material used by the Aeroseal air duct sealing system safe?

Yes. Prior to application, the sealant material is a water-based solution that consists of 65% water. After it dries, the sealant primarily contains two chemicals, vinyl acetate polymer (VAP) and 2-ethyl-1 hexanol (2E1H). Most of the sealant consists of VAP — which has been used in water-based paints, adhesives, hair spray and chewing gum and has no OSHA exposure limit. 2E1H is commonly used as an industrial solvent; OSHA does not consider 2E1H toxic. A literature review showed no ill effects after long-term exposure at concentrations of 200 parts per million; Aeroseal injections use concentrations of at most 1 part per billion, which is 200,000 times less.

In addition, Aeroseal’s sealant is UL-listed for smoke generation and flame spread (UL 723 0,0) and showed no signs of mold growth or erosion during additional UL testing.

UL

Does the sealing process leave an odor?

No — the Aeroseal air duct sealing process does not produce a lingering odor. The material does not produce or emit gas over time, so the sealant is odorless throughout the life of the product.

If the rooms of my home have inconsistent temperatures, can Aeroseal improve the performance of my heating and air conditioning system?

Yes — the Aeroseal duct sealing process improves your home’s comfort by creating consistent temperature levels between rooms and throughout the structure.

Can Aeroseal air duct sealing help lower my utility bills?

Many homeowners have seen energy bill savings of up to 40% after Aeroseal treatment. Typical homes will experience a measurable reduction in the amount of energy used for heating and cooling.

Can Aeroseal air duct sealing reduce the noise levels created by my home’s return and supply registers?

Noisy registers — or that loud rushing sound you hear when your HVAC system is running — usually stem from one or two conditions: Undersized ductwork or limited air flow through indoor heating and cooling coils. Your Aeroseal technician can help you identify the source of the problem and provide the best solution for noise reduction.

Can Aeroseal air duct sealing reduce the amount of dust in my home?

Yes. Ductwork runs through dusty spaces such as attics, basements, crawlspaces, garages and inside the walls. When the duct system has holes, cracks and leaks, return air ducts draw in dust and other indoor air pollutants and send this matter through the ductworks, where it enters the central heating and cooling system. From there, these particles are distributed through the air ducts to your home’s living areas, resulting in excessive dust and other particulate matter. Because the Aeroseal air duct sealing system can reduce the amount of leakage by up to 90%, dust and other indoor air pollutants aren’t drawn into your air ducts, so can’t enter the conditioned air in your home.

Is the sealing guaranteed? Can I get my money back if it doesn’t work?

Aeroseal provides a 10-year warranty on our sealing process. We have enormous confidence in the quality of our seals — they are based on Lawrence Berkeley National Laboratory research and a patent through the University of California. In addition, the Environmental Protection Agency and numerous local energy utility providers have endorsed the Aeroseal process. Overall, in the more-than 75,000 seals we’ve completed to date, we have received a negligible number of warranty claims.

Please note that warranties cover on-site seal failures only. Warranties do not cover:

  • Additional damage, such as an electrician stepping on a duct while working on wiring
  • Wear or tear, such as the shelf life of a plastic duct expiring, rodents causing duct damage, or rusting ducts
  • Subsequent replacement of failed ducts
