Ductwork Repair — Book a Visit Today
We repair, seal and replace residential ductwork across Texas, Oklahoma and Louisiana, so start by booking a duct inspection if some rooms never keep up. Duct problems usually come from disconnected boots in the attic, crushed flex runs, torn insulation, failed mastic at plenum joints and undersized returns that starve the blower. On a visit we check static pressure, open a few access points, look for daylight and dust streaks at seams, measure temperature at the registers and put eyes on the trunk and takeoffs. Then we show you what we found and give you the choice between sealing what is there or replacing runs that are past saving. Call us or send a message and we will schedule a look at your system.

The ductwork symptoms we hear most
- One bedroom is always ten degrees hotter than the rest of the house Disconnected or crushed branch run, or a supply boot pulled loose in the attic
- The AC runs and runs but the house never gets comfortable Conditioned air leaking into the attic or crawlspace through open seams
- Dust settles on the furniture a day after we clean Return-side leaks pulling attic dust and insulation fibers into the airflow
- Air barely moves out of the vents even with the fan on high Kinked flex, sagging runs, or undersized returns choking the blower
- The attic feels cool when we walk it in July Supply leakage and stripped or fallen duct insulation dumping cooling upstairs
Whether you call it ductwork repair, air duct repair or duct sealing, the work is identical and so is the quote you approve first.
Safe things to check first
Worth a look before you call — sometimes it saves you the visit.
- 1Check the thermostat: fresh batteries, set to cool or heat, and fan set to auto rather than on.
- 2Change the air filter if it is gray or matted. A loaded filter mimics a duct restriction.
- 3Walk every room and confirm supply registers and return grilles are open and not blocked by furniture or rugs.
- 4Look at the breaker panel for a tripped breaker on the indoor or outdoor circuit and tell us what you find.

How do you find a duct leak?
We start with static pressure and register readings, then inspect the accessible runs, plenum joints and boots for daylight, dust tracks and loose collars. Where access allows we pressure test the duct system so we are sealing real leaks, not guesses.
Is sealing enough or do we need new ductwork?
If the runs are intact and sized correctly, sealing joints, boots and plenum seams usually fixes it. If flex is torn, crushed, sagging between joists or the layout starves rooms, replacement of those runs makes more sense than patching.
Does leaky ductwork make my AC repair bills worse?
It can. Low airflow and leaking returns make the system run longer and load the blower and coil, which shortens component life. Fixing duct problems often resolves complaints homeowners assumed were an air conditioner repair issue.
How long does duct repair take?
Sealing and reconnecting a handful of runs is usually a same-day visit. Replacing an entire attic duct system takes one to a few days depending on the layout, attic access and how much of the trunk gets rebuilt.
Will new ducts fix a hot room upstairs?
Often yes, especially when the cause is a disconnected boot, a long kinked run or no return in that space. We measure airflow first so the fix targets the reason that room is short on air.
Do you work on ducts in crawlspaces as well as attics?
Yes. We repair and replace ductwork in attics, crawlspaces, garages and interior chases across the region. Access and clearance affect the approach, so we look at the space before we recommend sealing or replacement.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form with what you hear, smell or feel. Warm air, short cycling, a breaker that keeps tripping. Details on your porch help us arrive with the right parts.
- Step 2
We diagnose on site
A technician checks the thermostat, airflow, the indoor coil and blower, then the outdoor unit and electrical side. You get a plain explanation of what failed and why it failed.
- Step 3
You approve the repair
We walk you through the fix and any parts involved before we start. Once you say go, we make the repair and confirm the system is holding temperature before we leave your driveway.

Why homeowners call us
- Built for hard summersWe work on attic air handlers in July heat, undersized returns in older subdivisions, and condensers with hail-flattened fins. Those are everyday jobs across the region, so we know where these systems tend to give out first.
- Air conditioner repair and heating repairOne crew for both seasons. Air conditioning repair when the house won't cool, heater repair and furnace repair when the burners won't stay lit. Same technicians, same records, so nobody starts from scratch in November.
- We explain the failureYou hear which component failed and what it was doing to the rest of the system. If a repair is a short-term patch on an aging unit, we say so and let you decide the timing.
- Respect for the houseDrop cloths, shoe covers, and the attic hatch closed the way we found it. We keep the work area clean and we tell you honestly when a problem is airflow or ductwork rather than the equipment itself.
