Why Duct Leakage Is a Bigger Problem Than Homeowners Think
The Department of Energy estimates that ductwork in a typical Cherokee County home leaks 20 to 30 percent of all conditioned air directly into unconditioned spaces. That’s a third of your heating and cooling literally vanishing into your attic, crawl space, or wall cavities every minute the system runs. You paid to cool that air. You’re paying again because the AC has to make more to compensate.
The damage doesn’t stop at energy waste. Leaky ducts also pull dirty, dusty, humid attic air into your living spaces during the return cycle. That’s how Georgia attic air loaded with pollen, dust, insulation fibers, and humidity ends up circulating through your home. Sealing your ductwork solves both problems at once: recovering lost air and stopping contaminated air from entering your home.
Duct Sealing Services We Provide
We focus entirely on getting your cooling system right. Pick the service you need below to learn more, or call us if you are not sure where to start.
Professional Duct Leakage Testing
Pressure testing using calibrated equipment that measures exactly how much air your ducts leak. Industry standard testing identifies the actual problem before any sealing work begins.
Manual Duct Sealing
Hands-on sealing using mastic, foil-backed tape, and approved materials at every duct joint, register boot, and equipment connection. Targeted repair for accessible leaks.
Aeroseal Duct Sealing
Computer-controlled aerosolized sealant injected throughout your duct system that seals leaks from the inside. Best technology for hard-to-reach leaks in walls and ceilings.
Register and Boot Sealing
Sealing the connections between supply ducts and your floor or ceiling registers, one of the most common leak locations and easiest to verify and fix.
Return Duct Sealing
Particular attention to return air ducts, which under negative pressure pull air from wherever it leaks, including attics and crawl spaces. Fixing returns dramatically improves indoor air quality.
Equipment Connection Sealing
Sealing the connections between air handlers, plenums, and main trunk lines. These central connection points often leak more than the entire branch duct network combined.
How Our Duct Sealing Process Actually Works
We're not a franchise pulling trucks in from across Atlanta. Our technicians live right here in Cherokee County and treat your home like ours.
In-Home Inspection and Quote.
A technician inspects accessible ductwork, identifies obvious leak locations, and provides a written quote for testing and sealing.
Professional Pressure Testing.
We pressurize your duct system and measure leakage in cubic feet per minute. The before number tells us exactly how bad the problem is.
Targeted Sealing Work.
We seal every accessible leak using mastic, foil tape, and approved materials. For inaccessible leaks (walls, ceilings), we may recommend Aeroseal injection sealing.
Post-Sealing Verification Test.
We pressure test again after sealing to measure the improvement. You see the actual leakage reduction in writing.
Comfort and Performance Verification.
We measure airflow at each register to confirm balanced air distribution and walk you through what to expect from your now-sealed system.
Duct Sealing Cost in Woodstock
Duct sealing pricing in Cherokee County depends on home size, leak severity, and access. Basic duct sealing service runs $400 to $900 for accessible duct systems with moderate leakage. Full duct sealing with testing and verification runs $700 to $1,500 for typical homes. Aeroseal whole-system sealing runs $1,800 to $3,500 for homes with extensive inaccessible leakage. Combined duct sealing with insulation upgrades runs $1,500 to $4,500.
Most homeowners recover the cost through energy savings within 3 to 5 years. Combined with improved comfort and indoor air quality, the payback is usually faster than the pure utility math suggests.
When to Call vs. When to Wait
Some AC problems can wait until Monday. Others should not. Here's the difference.
Call now if:
- Energy bills have climbed without lifestyle changes
- Certain rooms never reach setpoint temperature
- You feel dust constantly accumulating
- Your HVAC system runs constantly during peak weather, or your existing ductwork is over 15 years old.
Schedule within a few weeks if:
- You've noticed inconsistent airflow at registers
- Your HVAC system seems to run longer than it used to
- You have allergy issues that get worse when the AC runs, or you're planning a new HVAC installation and want to maximize its efficiency.
Our technicians diagnose every AC issue using superheat and subcooling measurements, static pressure readings, and electrical performance testing. No guesswork, no parts cannon, no upsell pressure.

Frequently Asked Questions
Common signs include high energy bills, uneven temperatures between rooms, dusty surfaces despite regular cleaning, HVAC running constantly during peak weather, and unpleasant odors when the system kicks on. Professional duct leakage testing measures the exact leak rate so you know what you’re dealing with.
Yes, for most Cherokee County homes. The Department of Energy estimates duct sealing pays back through energy savings within 3 to 5 years. Add in improved comfort, better indoor air quality, and reduced HVAC strain extending equipment lifespan, and the value is usually significant beyond the energy math alone.
Traditional sealing uses mastic and tape at accessible duct joints. Aeroseal injects an aerosolized sealant throughout the entire duct system that finds and seals leaks from inside, including those hidden in walls and ceilings. Aeroseal costs more but addresses leaks traditional methods cannot reach.
Properly applied mastic and approved duct sealants last 15 to 20 years or longer. Aeroseal carries a 10-year manufacturer warranty. The seal lasts much longer than the wear and tear that originally caused the leakage, so once sealed, your ducts stay sealed for the life of the system.
