The Most Expensive HVAC Problem Nobody Can See
Testing consistently finds typical homes losing 20 to 30 percent of their conditioned air through duct leaks, disconnected joints and poorly sealed boots. In the Hill Country that air is usually being lost into a 150-degree attic — you paid to cool it, it never reaches a room, and the attic gets hotter, which makes the next hour worse.
Ducts are also where dust, allergens and the occasional rodent problem live. Cleaning and sealing are different jobs solving different problems, and we will tell you which one you actually need.

Cleaning or Sealing — Which Do You Need?
They solve different problems. Cleaning removes what is inside the ducts and helps with dust and air quality. Sealing stops conditioned air escaping and helps with comfort and bills. Plenty of homes need one and not the other, which is why an inspection is the honest first step rather than a package quote.
Frequently Asked Questions
Can Duct Sealing Improve My Home’s Indoor Air Quality?
How Duct Sealing Improves Indoor Air Quality
Leaky ductwork doesn’t just waste energy, it can also pull in dust, insulation particles, and other contaminants from areas like attics, crawl spaces, or wall cavities. When your ducts are sealed, those unwanted pollutants are kept out of your airflow. Here’s how duct sealing helps improve air quality:
- Prevents dust and allergens from entering the duct system
- Reduces the spread of pollutants throughout your home
- Improves filtration by keeping air moving through the proper system path
- Supports better overall airflow and ventilation
In many homes across the Texas Hill Country, ductwork runs through hot, dusty attic spaces. If there are leaks, your system can pull in that air and circulate it throughout your home. Sealing ducts helps ensure the air you’re breathing is coming through your filtration system, not from unconditioned spaces. 72 Degrees Texas can inspect your ductwork and recommend sealing solutions to help homeowners in Fredericksburg, Kerrville, and surrounding areas improve both comfort and indoor air quality.
Can You Insulate Ductwork In The Attic?
Why Insulating Attic Ductwork Is Important
Yes, ductwork in the attic can and should be insulated. Attics in the Texas Hill Country can reach extremely high temperatures, which can significantly impact how your HVAC system performs. Without insulation, cooled or heated air traveling through ducts can lose energy before it ever reaches your living space. Insulating attic ductwork helps:
- Reduce energy loss during heating and cooling
- Improve overall HVAC system efficiency
- Maintain more consistent indoor temperatures
- Reduce strain on your system during extreme weather
- Prevent condensation that can lead to moisture issues
Common insulation methods include duct wrap and pre-insulated duct materials, depending on the condition and layout of your system. In homes throughout Fredericksburg, Kerrville, and surrounding areas, attic duct insulation is one of the most effective ways to improve comfort and reduce energy costs. 72 Degrees Texas can inspect your ductwork and recommend the right insulation solutions to help your system perform at its best.
Does 72 Degrees Texas Use Special Equipment Or Techniques For Air Duct Cleaning?
Professional Air Duct Cleaning Methods And Equipment
Air duct cleaning requires more than basic tools. 72 Degrees Texas uses specialized equipment designed to clean your duct system thoroughly without damaging it. Professional cleaning typically involves:
- High-powered vacuum systems to remove dust and debris from ducts
- Rotating brushes or agitation tools to loosen buildup inside duct walls
- Inspection tools to identify problem areas before and after cleaning
- Containment methods to keep debris from spreading into your home
These techniques allow technicians to reach deep into your duct system and remove contaminants that standard cleaning methods can’t address. In the Texas Hill Country, where dust and debris can build up quickly, professional duct cleaning helps maintain airflow and improve overall system performance. 72 Degrees Texas combines the right equipment with experienced technicians to deliver thorough, effective duct cleaning for homeowners in Fredericksburg, Kerrville, and surrounding areas.
How Do You Insulate HVAC Ductwork?
How HVAC Ductwork Is Properly Insulated
Insulating HVAC ductwork is a multi-step process that improves efficiency and helps your system deliver air at the right temperature. The first step is always sealing the ducts. Insulation alone won’t be effective if air is leaking out of the system. Here’s how the process typically works:
- Inspect the duct system for leaks, gaps, or disconnected sections
- Seal any leaks using mastic, tape, or advanced methods like Aeroseal
- Wrap ducts with insulation, such as fiberglass duct wrap
- Secure insulation with proper fasteners and vapor barriers
- Ensure all joints and seams are fully covered and protected
In some cases, pre-insulated duct materials may be used, especially during new installations or major upgrades. Insulating ductwork is especially important in unconditioned spaces like attics, where extreme temperatures can quickly affect airflow and system performance. For homes in Fredericksburg, Kerrville, and across the Texas Hill Country, proper duct insulation can make a noticeable difference in comfort, efficiency, and energy costs. 72 Degrees Texas can evaluate your duct system and handle both sealing and insulation to ensure your HVAC system performs as efficiently as possible.
How Much Does Aeroseal Duct Sealing Cost?
What To Expect For Aeroseal Duct Sealing Costs
Aeroseal duct sealing is priced based on your home’s size, the condition of your ductwork, and how complex your system is. Most homeowners can expect to pay anywhere from $1,500 to $4,000 for a typical home, though larger or more complex systems can reach $6,000 or more. Several factors influence the total cost:
- Size of your home and total ductwork
- Amount of air leakage that needs to be sealed
- Accessibility of ducts in attics, crawl spaces, or walls
- Whether testing and verification are included
- Local labor rates in the Texas Hill Country
Aeroseal is often more efficient than traditional duct sealing because it seals leaks from the inside, including areas that are hard to reach manually. The process typically includes pre-testing, sealing, and post-testing to verify results. For homeowners in Fredericksburg, Kerrville, and surrounding areas, sealing ducts can improve airflow, increase energy efficiency, and reduce strain on your HVAC system. The most accurate way to get pricing is through a professional evaluation, since every home’s duct system is different.
