Expert Duct Sealing in Austin, TX

Performance-Tested Air Duct Sealing for Real Comfort & Energy Savings

Most Austin homes lose 20–30% of conditioned air through leaky ductwork, leading to high energy bills, hot rooms, and poor HVAC performance.

If your home never feels comfortable — even after installing a new air conditioning system — the real issue may be hidden duct leakage or airflow problems.

At Breeze Air Conditioning, we provide diagnostic-driven duct sealing services designed to improve airflow, reduce energy waste, and restore consistent comfort in residential homes across the Austin area.

Unlike many HVAC companies that rely on visual inspections alone, we use building science principles and quantitative performance testing to ensure your duct system operates efficiently.

Our owner has been diagnosing residential comfort and energy problems since 2009.

Why Duct Sealing is Critical for Austin Homes

Austin’s long cooling season and extreme attic temperatures create harsh conditions for residential duct systems.

Leaky or poorly designed ductwork can cause:

• Significant energy loss before cooled air reaches living spaces

• Uneven temperatures between rooms or floors

• HVAC systems running longer than necessary

• Rising electricity bills during peak summer months

• Indoor air quality issues from attic air infiltration

• Reduced comfort even after HVAC equipment replacement

Many homeowners believe their AC system is failing when the real issue is air distribution inefficiency within the duct system.

Our Performance-Based Duct Sealing Services

We focus on measurable system improvements rather than guesswork.

✔ Quantitative Duct Leakage Testing

We measure total air duct leakage using professional diagnostic equipment to identify performance issues and verify improvements.

✔ Manual Air Duct Sealing with Mastic

We apply industry-approved mastic sealing methods to permanently reduce leakage at joints, seams, and connections.

✔ Foil Tape Reinforcement

Strategic reinforcement improves long-term duct durability and system integrity.

✔ Targeted Ductwork Repair or Replacement

If ducts are undersized, damaged, or poorly designed, we provide full duct system improvement solutions.

✔ Attic Insulation Improvements

Proper insulation works together with sealed ducts to maximize HVAC efficiency and indoor comfort.

Our Proven Duct Diagnostic & Sealing Process

Most HVAC companies seal ducts based on assumptions. We do not seal ducts blindly.

We follow a structured building-science diagnostic workflow.

Step 1 — Whole-Home Comfort & Energy Assessment

We evaluate:

• Comfort complaints and hot room patterns

• Energy usage trends

• HVAC runtime behavior

• Airflow concerns

Step 2 — Professional Duct Leakage Measurement

We quantify:

• Total duct leakage (CFM)

• Leakage percentage relative to system size

• Leakage location patterns

• Pressure imbalances affecting airflow

Step 3 — Airflow & Static Pressure Diagnostics

We measure:

• Room-by-room airflow delivery

• System static pressure

• Duct sizing and design limitations

Step 4 — Targeted Duct Sealing & System Improvements

We implement:

• Professional mastic sealing

• Foil HVAC tape reinforcement

• Duct design corrections where needed

• Insulation upgrades if contributing to performance loss

Step 5 — Post-Improvement Verification Testing

After improvements, we verify:

• Reduced leakage percentage

• Improved airflow performance

• Enhanced HVAC system efficiency

This ensures homeowners receive measurable, verified results.

Why Many HVAC Companies Misdiagnose Comfort Problems

Most contractors focus only on equipment performance. However, comfort and efficiency are often determined by air distribution system design and integrity.

Common misdiagnoses include:

• Replacing AC equipment instead of fixing duct leakage

• Ignoring airflow balance issues

• Overlooking attic thermal conditions

• Failing to perform diagnostic testing

At Breeze Air Conditioning, we focus on root-cause problem solving using measurable data.

Our services are especially effective for:

• Older Austin homes with aging duct systems

• Homes experiencing high electric bills

• Properties with persistent comfort complaints
