When Repair Isn't Enough

Some Ductwork Is Too Far Gone to Patch.

Houston homes built before the 1990s often have ductwork that's reached the end of its useful life. Older flex duct degrades — the inner liner cracks, the insulation separates from the duct body, and joints that were taped with standard duct tape (which dries out and fails within a few years) open up. At some point, patching and sealing stops being cost-effective and a full replacement is the right move.

Replacement also makes sense when the existing duct system was never sized correctly for the home. Many older Houston homes were designed with undersized supply runs, too few return air pathways, or trunk-and-branch layouts that don't distribute air evenly. A new duct system is an opportunity to redesign airflow from scratch — properly sized for your HVAC equipment and your home's actual layout.

We assess your existing ductwork, document what needs to come out, design the replacement system, and install it completely — including all insulation, sealing, and airflow balancing. Financing is available so you can do it right without waiting.

What You Get

New Ducts.
Full Performance Restored.

A new duct system doesn't just fix airflow — it unlocks the full capacity of your HVAC equipment and keeps it running at peak efficiency for the next 20 years.

Like-New Airflow
New properly-sized ductwork delivers conditioned air to every room at design velocity. No more hot spots, no more rooms that never cool down, no more vents that barely move air.
Energy Efficiency Restored
Deteriorated or leaky ducts dump conditioned air into your attic instead of your rooms — your compressor runs longer and costs more. New sealed ducts mean all that energy goes exactly where it should.
Cleaner Indoor Air
Old, cracked ductwork pulls in attic air — dust, insulation fibers, humidity, and anything else living up there. New ducts, properly sealed, keep your air supply clean from the air handler to the register.
Financing Available
Full duct replacement is a significant investment that pays off in energy savings and equipment longevity. We offer financing options so you can do it right now — not piecemeal over years.
What's Included

Everything From Old Ducts Out to New System Balanced

Full duct replacement is a complete process — from assessment to airflow verification. Here's every step we handle.

01
Full System Assessment & Design
We inspect all existing ductwork — measure static pressure, check for undersized runs, identify return air deficiencies, and document what needs to be replaced. Then we design the replacement system using Manual D duct sizing methodology, matched to your HVAC equipment's airflow requirements. You get a system designed for your home, not a copy of what was there before.
02
Remove Old Ductwork
We remove all existing ductwork completely — supply runs, return air plenums, boots, and any failing trunk lines. Old flex duct that's been in a Houston attic for 15+ years is typically degraded beyond salvage. We haul everything out and prepare for a clean installation.
03
Install New Insulated Duct System
We install new R-8 insulated flex duct (or sheet metal where appropriate), properly supported and routed for minimum restriction. All connections are sealed with mastic — not tape, which dries out and fails. Supply and return plenums are rebuilt to match the new layout. Every boot is secured and sealed to the ceiling or floor.
04
Balance, Test & Verify
After installation, we measure airflow at every register with a flow hood and balance the system — adjusting dampers and register sizes until every room receives the right CFM for its size. We run the system through a full cooling cycle and verify static pressure is within design range before signing off.

FAQ

Duct Replacement Houston TX — Common Questions

How much does duct replacement cost in Houston?
Full duct system replacement in Houston typically costs $2,500–$7,500 for an average home, depending on square footage, number of zones, duct material, and attic conditions. Partial replacements (replacing specific runs or sections) cost less. Master Cooling Connection provides free duct assessments with itemized, flat-rate pricing before any work begins.
How long does full duct replacement take?
A full ductwork replacement for an average Houston home takes 1–3 days. Larger homes or complex layouts may take longer. We work efficiently to minimize time your system is down, especially important during Houston's hot summer months. Most projects are completed within 2 days.
When should I replace ducts instead of repair them?
Duct replacement is typically the right call when: ducts are more than 15–20 years old, more than 25% of duct surface is damaged or disconnected, ducts are poorly designed causing chronic airflow problems, or mold/pest damage has compromised duct integrity. Our technicians assess your system and give you an honest recommendation — repair vs. replace — based on actual conditions.
What duct materials does Master Cooling Connection install?
We install flexible ductwork, rigid sheet metal ductwork, and duct board depending on your system design and budget. For Houston's hot attic environments, we use properly rated flex duct with high-quality insulation or recommend sheet metal for longer runs. All installations are sealed and insulated to code.
Does duct replacement require a permit in Texas?
Yes. Full duct system replacement requires an HVAC permit in most Texas cities. Master Cooling Connection (license TACLA148713E) manages all permit applications and city inspections as part of the project at no extra hassle to you.
