Signs Your Houston Home Needs Air Duct Replacement
Ductwork wears out quietly, and most homeowners only notice once comfort or costs are affected. At 75 Degree AC, our technicians look for these warning signs before recommending air duct replacement Houston homeowners can trust:
- Some rooms stay warm while others stay cool, even with the system running nonstop
- Your energy bills have crept up without any change in how you use your AC
- You can see cracks, holes, sagging, or disconnected sections in the ductwork
- Dust, mold, or a musty smell keeps returning no matter how often you clean
- Your ducts are original to a home built before energy codes tightened, often 15 years or older
- Ducts run through a Houston attic that regularly hits 130°F or higher in summer, breaking down seals and insulation over time
Air Duct Repair vs. Replacement: How We Help You Decide
Not every damaged duct needs a full system overhaul. Our technicians inspect the ductwork first, then walk you through what we found and why, so the choice is yours to make.
When Air Duct Repair Houston Homes Need Is Enough
- Damage is limited to one or two sections, not the whole system
- Leakage tests show air loss under 10 percent
- Insulation still holds most of its original R-value
- Ductwork is under 10 years old with no signs of widespread wear
- Seals and joints can be resealed without cutting into the duct material
When Houston TX Air Duct Replacement Is the Right Call
- Multiple sections show cracks, crushing, or disconnection
- Leakage tests show air loss above 20 percent
- Insulation has degraded and no longer meets current R-value standards
- Ductwork is original to a home built more than 15 years ago
- Repeated repairs have not resolved airflow or comfort issues
Our Air Duct Replacement Process in Houston
75 Degree AC follows a set process for every air duct replacement in Houston, so nothing gets skipped and nothing is left to guesswork. Here is how our duct replacement Houston projects move from inspection to final walkthrough.
Full System Inspection
We check every duct run, joint, and connection point to see where damage or leakage is occurring.
Load Calculation and Sizing
Our techs calculate your home's heating and cooling load to size the new ductwork correctly, not by guesswork.
Material Selection
We help you choose between sheet metal, flexible duct, or duct board based on your attic space and budget.
Old Duct Removal
Damaged ductwork is carefully removed without disturbing insulation, wiring, or other parts of your attic.
New Duct Installation
New ducts are installed to the sizing plan, routed to reach every room evenly.
Sealing Every Joint
Each connection is sealed with mastic, not just tape, to stop conditioned air from leaking out.
Airflow Testing
We measure airflow at each vent to confirm the new system is delivering the air it should.
System Balancing
Dampers are adjusted so no single room gets more airflow than the rest of your home.
Final Inspection and Walkthrough
We walk the full system with you, answer questions, and confirm everything meets code before we call the job done.
Ductwork Materials & Sizing Standards We Follow
We work with sheet metal, fiberglass duct board, and flexible duct, and we recommend the option that fits your attic layout and airflow needs. Every air duct replacement Houston project starts with the right material, not a default one.
Sizing follows Manual J for load calculations and Manual D for duct design, so airflow matches what your home actually needs. This keeps the work in line with local building codes and avoids the underperformance that comes from guessed sizing.
Why Houston's Climate Makes Proper Duct Replacement Critical
Houston attics regularly climb past 140°F in summer, and that heat breaks down duct seals and insulation years faster than in milder climates. This is why air duct replacement in Houston needs materials rated for extreme attic conditions, not standard-grade duct.
Add in Gulf Coast humidity, and any small leak turns into condensation, then mold, inside the duct system. Older homes inside the loop often still run undersized ductwork from decades ago, which makes proper replacement even more important for these properties.
Why Houston Homeowners Trust 75 Degree AC
Every air duct replacement in Houston we complete is backed by real credentials, not just a promise. Here is what stands behind our work.

Air Duct Replacement Cost in Houston: What Affects Your Price
The price of air duct replacement in Houston depends on your home’s size, the material you choose, and how many vents and runs need replacing. Attic access also plays a role, since tight crawlspaces take more time than an open attic.
Homes that need resizing to fix airflow problems cost more than a straight swap of old ductwork for new. We walk through these factors with you before any work starts, so your quote reflects your home, not a flat rate.

Frequently Asked Questions
How long does air duct replacement take?
Most Houston homes take one to two days, depending on home size and attic access.
Do I need to replace all my ducts, or just some?
Not always. We inspect each run separately and only replace sections that fail our leakage and damage checks.
Will replacing my ducts lower my energy bill?
Sealed, correctly sized ductwork reduces air loss, which typically lowers cooling costs. Exact savings depend on your current duct condition.
Is a permit required for duct replacement in Houston?
Yes, most duct replacement work requires a permit. We handle the permitting process as part of the job.
How disruptive is the process to my home?
Work mainly happens in the attic, so daily disruption to living spaces is minimal. We protect floors and walkways during the job.
Can I stay in my home during the replacement?
Yes, homeowners typically stay in the home while we work, since access is limited to the attic and vent locations.
What happens to my old ductwork?
We remove and dispose of the old material as part of the service, so there’s nothing left for you to handle.

Frequently Asked Questions

Simple tasks like swapping a dirty air filter or resetting your thermostat are fine to handle yourself.

Attempting those repairs without proper certification is unsafe and illegal in Texas.
How Often Should I Service My Central Air Conditioner?

Houston’s long cooling season puts more hours on your equipment than most other regions.ds seven days a week. These older communities often deal with aging ductwork, worn AC contactors, and failing capacitors. Licensed technicians cover all these areas daily.
