MAXIMIZE YOUR HOME'S EFFICIENCY

Stop Wasting Money on Leaky Air Ducts

Did you know that cracks, leaks, and poor connections in your ductwork could be costing you a significant amount of money? Leaky ducts can lose 20 to 30 percent of the conditioned air that passes through them, forcing your HVAC system to work harder and longer to keep your home comfortable. This wasted energy translates directly into higher utility bills and unnecessary strain on your heating and cooling equipment.

At AA Service Co., we provide professional air duct sealing services to homeowners throughout Chicagoland, from Highland Park to Evanston. Our advanced sealing process locates and closes leaks from the inside out, restoring your ductwork to peak condition. By ensuring conditioned air reaches its intended destination, you can enjoy improved comfort, better indoor air quality, and substantial energy savings for years to come.

HOW IT WORKS

Our Thorough Duct Sealing Process

We follow a proven, meticulous process to ensure every crack and leak in your ductwork is properly sealed for maximum efficiency and performance. Our technicians work carefully and cleanly, treating your home with the respect it deserves from start to finish.

System Inspection & Preparation

We begin by thoroughly inspecting your ductwork. Our technicians will then block off all your registers and vents to pressurize the system for a pre-seal leakage test.

Computerized Leakage Test

We use advanced diagnostic tools to measure the exact amount of air leakage in your duct system, providing a clear baseline for improvement.

Inject Non-Toxic Sealant

Our team injects a safe, water-based aerosol sealant into the pressurized duct system. The particles find and adhere to the edges of any leaks, building up a durable seal from the inside.

Real-Time Monitoring

Throughout the process, we monitor the sealing progress in real-time, watching as the duct leakage rate drops and confirming that the system is becoming airtight.

Post-Seal Certification

Once the sealing is complete, we perform a final leakage test and provide you with a certificate that verifies the significant reduction in air leaks and the newfound efficiency of your system.

ENERGY EFFICIENCY

Lower Your Monthly Utility Bills

The primary benefit of professional air duct sealing is the significant improvement in your home’s energy efficiency. When conditioned air escapes through leaks before it reaches your living spaces, your furnace or air conditioner has to run longer and harder to maintain the temperature set on your thermostat. This constant over-compensation is a major source of energy waste in many homes.

By sealing these leaks, you ensure that nearly all the heated or cooled air your system produces is delivered where it’s needed. This allows your HVAC equipment to reach the desired temperature more quickly and cycle off sooner, dramatically reducing its overall runtime. The direct result is lower energy consumption and noticeable savings on your monthly heating and cooling bills.

INDOOR AIR QUALITY

Breathe Cleaner, Healthier Air in Your Home

Your ductwork doesn’t just carry air; it can also be a pathway for dust, allergens, and other pollutants. Leaks in your duct system, especially those in attics, crawlspaces, or basements, can pull in dirty, unconditioned air from these spaces and circulate it throughout your home every time your HVAC system runs.

This unfiltered air can introduce dust mites, mold spores, insulation particles, and other contaminants into your living environment. For family members with allergies, asthma, or other respiratory sensitivities, this can worsen symptoms and create an unhealthy atmosphere. Poor air quality can affect everyone, leading to everything from lingering odors to general discomfort.

HAVE QUESTIONS?

Frequently Asked Questions About Duct Sealing

To help you make an informed decision about your home’s efficiency, we’ve answered some of the most common questions we receive about our air duct sealing services. If you have any other questions, please don’t hesitate to reach out to our knowledgeable team.

How do I know if my air ducts are leaking?

Common signs of leaky ducts include unusually high utility bills, rooms that are difficult to heat or cool, stuffy or stale air, and excessive dust in your home. The most accurate way to know for sure is with a professional inspection and pressure test.

We use an advanced method where we pressurize your duct system and inject a non-toxic, aerosolized sealant. The sealant particles are drawn to leaks and build up to create a strong, durable seal from the inside out, without the need to tear into walls or ceilings.

Absolutely. The sealant we use is a water-based, non-toxic material that is completely safe. It has been used in hospitals and homes for many years and has very low VOCs (Volatile Organic Compounds), ensuring it won’t impact your indoor air quality.

For a typical single-family home, the entire process can usually be completed in just a few hours. Our technicians work efficiently to minimize any disruption to your day.

While savings vary based on the severity of the leaks, your energy usage, and local utility rates, it’s not uncommon for homeowners to save up to 20-30% on their heating and cooling costs after having their ducts professionally sealed.
