You should not have to choose between a comfortable living room and a bedroom that never feels right. When conditioned air escapes through duct leaks, the air your system heats or cools may not reach the rooms where you need it.
Breeze offers Aeroseal duct sealing as part of a home-specific conversation about comfort, airflow, and efficiency. We start with the duct system, not a promise that one product fixes every uncomfortable room.
Start with the rooms that do not feel right.
A bedroom that is harder to heat. A room that feels warmer than the rest in summer. Airflow that seems weak at some registers. These are useful reasons to look beyond the thermostat.
Duct leakage is one possible cause. Insulation, duct layout, disconnected runs, equipment settings, and other conditions may contribute too. An assessment helps separate the issues so you are not buying a solution for the wrong problem.
- Rooms regularly feel different from neighboring rooms.
- Some registers seem to deliver less air than others.
- Ducts run through an attic, crawlspace, or other unconditioned area.
- An addition or equipment change has raised airflow questions.
Dust and indoor-air concerns are also worth discussing, but sealing does not replace filtration, ventilation, source control, or addressing moisture. Explore indoor-air options alongside your ductwork questions.
Understand the system before choosing the fix.
A duct-focused review considers accessible condition, connections, routing, equipment operation, and the concern you are noticing. Leakage testing can help make the conversation more concrete.
Some problems call for a physical repair, a different duct layout, or a broader HVAC assessment. Aeroseal is not a replacement for fixing a disconnected or severely damaged duct. Conventional sealing of accessible joints may also be part of an appropriate plan.
Tell us if you are also planning a heating or cooling replacement. Equipment and airflow decisions belong together when they affect the same home-comfort goal.
Sealing from the inside
How Aeroseal works
Prepare and measure
The duct system is prepared for the process. Registers are temporarily blocked and relevant equipment components are protected. Connected testing equipment measures the leakage before sealing begins.
Target the leaks
Aeroseal uses air-carried sealant particles inside the prepared ductwork. The particles collect at leakage points as air escapes, building a seal there rather than simply coating the entire duct interior. Software monitors the sealing process.
Compare the results
Post-sealing testing provides a measured comparison with the initial leakage test. The project scope should explain what will be tested, how the home is prepared, and what report you will receive.
The process description comes from Aeroseal’s supplied website guidance. Any expected comfort or operating-cost benefit still depends on the specific home, system, and work performed.
Reports supplied by Breeze
A before-and-after result you can understand.
Brian supplied two Aeroseal result reports from Breeze work. They show measured duct-air leakage before and after sealing at the same test pressure. They are separate project examples, not a guarantee for your home.
Report example 1
- Before sealing
- 186 CFM at 25 Pa
- After sealing
- 26 CFM at 25 Pa
- Reported leakage improvement
- 85.8%
Report example 2
- Before sealing
- 194.05 CFM at 25 Pa
- After sealing
- 46.43 CFM at 25 Pa
- Reported leakage improvement
- 76.1%
CFM means cubic feet of air per minute. Pa means pascals, a pressure measurement. These figures describe leakage-test changes only. They are not percentages of energy-bill savings, room-temperature improvement, or health benefits. No customer identity, location, or equipment model is attached to these examples.
For your project, ask Breeze to walk through the actual report and explain how the measurements relate to the ductwork and your goals.
Comfort made a Breeze starts with the whole picture.
Sealing may be one useful part of improving how conditioned air reaches your rooms. A thoughtful recommendation considers equipment, ducts, insulation, and the way you live in the home, not a single product in isolation.
Explore ductwork and airflow assessment, heat-pump planning, or room-by-room ductless options if those questions fit your project. For payment or incentive questions, visit Financing and Rebates & Incentives; confirm current details separately.
Your duct-sealing questions
Will Aeroseal fix every hot or cold room?
No. Uneven comfort can have several causes. A duct and system assessment should guide whether sealing, repair, equipment work, or another option belongs in the plan.
How is Aeroseal different from sealing an accessible joint?
It targets leakage from inside a prepared duct system using air-carried sealant particles. Conventional external sealing is applied at accessible connections. The appropriate approach depends on the condition and access of the ductwork.
What do the before-and-after report numbers mean?
They compare measured air leakage at a stated test pressure. A lower after-sealing number shows less leakage in that test. It does not directly tell you how much your utility bill will change.
Can I ask about sealing before replacing my HVAC system?
Yes. Existing ducts and airflow are useful parts of the replacement conversation. The right sequence depends on the assessment and project scope.
Tell us which room you wish felt better.
Start with what you notice. We can talk through whether a duct assessment or Aeroseal belongs in your home-comfort plan, with clear recommendations and no pressure to choose work you do not need.
