Everything You Need To Know About Aeroseal


An unsealed air return system can make for a dusty home!

leaky return ducts create a dusty home

Pollutants from unconditioned spaces get sucked into your ducts leaving you with lots of dust and poor air quality

Sealing air return ducts is important to you and your family’s health and well-being. The American College of Allergy, Asthma & Immunology estimates that 50% of all illnesses are caused by poor indoor air quality (IAQ). The EPA lists indoor pollution as one of the top five environmental risks to public health, causing 8.5 million deaths each year.

Leaky return ducts will result in having:

  • Dusty home and more frequent filter changes
  • Poor and unhealthy indoor air quality
  • Uncontrollable humidity problems
  • Possible mold growth inside of your ducts from moisture
  • Increased energy consumption
what are return vents and where are they located?

Return vents (also referred to as cool air return vents) pull the air from your rooms into your return ducts and send it back to your heating and cooling system. Return vents are usually larger than supply vents, and you will not feel air being blown out of them. Ductwork for returns is typically found in unconditioned spaces of your home, such as attics, inside walls or under floors, and even crawlspaces and basements. These spaces are often unreachable for contractors to fix or seal after the home is built without the need to demo and renovate.

why it’s important to seal air return ducts

Most people assume that furnace filters are enough to collect the average amount of dust being circulated inside their home, but a leaky return will cause you to replace filters at a faster rate and if left in too long can put strain on your system. An unsealed air return duct system not only sucks in dirt, dust, allergens, smelly odors, and other pollutants from attics, crawlspaces, and interior walls, but it also brings in humidity from those very same spaces. The introduction of humidity into the ductwork causes comfort issues, and can also lead to mold growth. Sealing your return ducts eliminates the threat of moisture and mold as well as block out all those pollutants from being introduced into your home and being recycled over and over again every day.

take control of dust with aeroseal

Sealing your ductwork with Aeroseal increases your home’s indoor air quality, helping to eliminate dust, allergens, and odors coming inside from unconditioned spaces.

Blocks Dust & Allergens To Create a Cleaner Environment Sealed air returns stop gross dust, dirt, allergens, and other air pollutants from being introduced into your system and then blasted all over your house.

Provides Healthier Airflow Throughout Your Home

In addition to greater airflow coming out of your vents, sealing your ducts blocks out all the filthy dust, dirt, and allergens, providing the fresh air that you expect and putting your mind at ease.

Control Humidity Issues and Avoid Mold Growth

Sealing your air returns will block humid and unconditioned air from entering the system and eliminate the threat of mold growth inside your ducts.

And poor system performance leads to higher energy bills.

Get The Efficiency You Paid For

Sealing your ducts is the best way to achieve maximum efficiency from your equipment.

Sealing and insulating your ducts increases system efficiency, lowers your energy bills, and can often pay for itself in energy savings. Plus, if you’re planning to install new heating and cooling equipment, a well designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification.

Impact is up to 50% greater on AC performance if return air leakage is from a hot attic or attached garage. Impact is typically 50% to 100% greater on winter heating performance of a heat pump with electric resistance auxiliary heat.

25-40% energy loss

“Typical duct systems lose 25-40 percent of the heating and cooling energy put out by the central furnace, heat pump or air conditioner. Duct repairs could be the most important energy improvement measure you can do.”

U.S. Department of Energy Consumer Report

“For an average home, leaky ducts can waste hundreds of dollars each year. Duct leakage also lowers the heating and cooling capacity, and can lessen equipment life.”

thinking about buying a new a/c or heating system?

Don’t let your old ducts keep you from getting the high performance you are paying for!

An investment in a new high efficiency heating and cooling system should save significantly on your utility bills. However, you won’t save much if your existing ductwork is in bad shape.

Plus, if you’re planning to install new heating and cooling equipment, a well designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification.

Here’s a short checklist of steps to take when looking into replacing your equipment:

  • Slow down and do your research
  • Find a contractor who can follow best industry practices when selecting a new system
  • Get a comprehensive home & duct performance assessment
  • Have test ran to measure air duct leakage, airflow and static pressure
bigger is not always better

Does your current system seem to run non-stop, or do you have rooms that are too hot or too cold? If you were unhappy with your old unit, don’t just assume you need bigger equipment. The real cause may be a bad duct system. It’s rare to find a unit that actually is undersized. More often, the real problem is a weak duct system, air leaks, missing insulation, or inadequate maintenance.

Buying new high efficiency heating and cooling equipment, and then hooking it up to the typical inefficient duct system, is like buying a super-fuel efficient hybrid car and then driving it with a leak in the gas tank.

An Oversized Heating & Cooling System Leads To:

  • Higher Utility Bills
  • More Breakdowns & Repair Bills
  • Uneven Temperatures
  • Uncomfortable Summertime Humidity
  • Increased Noise
  • Greater Duct Leakage
  • Increased Mold, Dust Mites and Allergies
