Air Duct Repair resolves a multitude of problems in your home. Pollutants from unconditioned spaces get sucked into your ducts leaving you with a lot of dust and poor air quality. Even newer HVAC systems cannot operate efficiently when there are leaks in the air duct system.

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
  • Poor HVAC system performance

Air McCall offers Air Duct Repair services for existing ductwork, or we will apply it when installing a new system, whichever the case is. Aeroseal technology is a fast, safe, and effective way to seal duct leaks. There are many benefits to using Aeroseal.

Indoor Air Quality

Most importantly, it removes the dust and excessive humidity from your duct system. This helps with a plethora of health issues. 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.

HVAC System Performance

Leaky ducts lead to decreased system performance. Sealing and insulating your ducts with Aeroseal technology 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.

Home Comfort

For many people, about 90% of their time is spent indoors. However, regardless of how much time you spend at home, the interior comfort of your home is important while you are there. Aeroseal technology will balance out the temperatures of your home by balancing air flow and humidity. It removes “dead zones” and evens out the temperature in every room.

Using Aeroseal technology for Air Duct Repair saves energy. We mentioned previously that each home can have energy loss due to leaks in the ductwork system. Aeroseal puts that money back in your wallet, where it belongs. Put simply, saving energy is saving money and you will see a decrease in your energy bills.

Aeroseal treatments have been proven to last up to 40 years. It is the most effective process available today. We provide fast and cost-effective air duct repair to homeowners in Jacksonville and the surrounding areas.



First, we block all your vents and registers to pressurize your system.

The internal components of your furnace are also blocked off to protect them from the sealant being blown through the ductwork.

This system pressurization allows our technology to find all the cracks and holes where air is leaking.

Next, we hook up the Aeroseal machine to measure your pre-seal air duct leakage, giving you a before and after snapshot. More on that later.



We are then ready to begin distributing our sealant formula throughout your air vent and duct system.

While sealing, we monitor your system’s performance and show you all the improvements, as they happen.

Our technology is so precise that we only use the amount of sealant necessary with virtually no waste and very little cleanup.

This process can vary between 60 minutes to a couple hours, depending on your initial system leakage amounts.



When we’re finished, a certificate of completion, including both before & after system leakage measurements, is printed and presented to you.

Breathe easy knowing your investment is backed by a 10 year warranty, and last many years longer.

More importantly, you’ll feel the difference in your home right away.
