Air Duct Cleaning Company in South Alamo, TX
Air duct repair in South Alamo is a different job than it is almost anywhere else in Texas. Much of the housing in and around ZIP 78516 went up as self-help or contract colonia housing through the middle and late 20th century, and the ductwork followed the house rather than the other way around: ad-hoc flex runs, window-unit retrofits, plenums that were never sealed. Add a subtropical climate that keeps the air conditioner running most of the year and you get ducts that sag, tear and separate long before anyone thinks to look at them. We clean, repair and protect duct systems here with industrial equipment. Call (888) 971-5813.
Why South Alamo Homes Are Different
South Alamo sits in the heart of the Rio Grande Valley’s frontera colonia belt, and that geography explains most of what our technicians run into. Ductwork was rarely engineered in this part of Hidalgo County. It was pieced together, room by room, as a house grew or as an evaporative cooler got swapped for central air. The result is a system with more joints, more transitions and more opportunity for failure than a tract home built to a single plan.
The climate does the rest. Gulf humidity is the primary duct concern here, not dust alone. Moisture intrudes at seams and at the plenum, and condensate problems build up because the system never gets a real off-season. Attic flex duct takes 100°F-plus heat for months, and it sags, tears and pulls apart at the plenum. When a run separates up there, cooled air blows straight into the attic instead of into the room. That shows up on the electric bill long before anyone climbs up to check. Small stucco-block houses and manufactured homes are common, and both tend to hide their worst duct connections behind ceiling panels or belly wrap.

Our Main South Alamo Services
Two services account for most of the calls we take from South Alamo homeowners.
Air Duct Cleaning in South Alamo
Cleaning a duct system in South Alamo starts with the assumption that some of it is already compromised. Our technicians open the system, inspect the flex runs and the plenum, and check for separations before contact cleaning begins. We use Rotobrush contact cleaning to agitate what has bonded to the duct walls, then Nikro industrial extraction to pull it out of the system. Abatement Technologies filtration runs during the work so the cleaning itself does not push dust into the living space. For a full explanation of the process, see Air Duct Cleaning in South Alamo.
Dryer Vent Cleaning in South Alamo
Dryer vents in colonia housing are often the shortest, most improvised run in the house – a flexible foil line pushed through a wall or up into an attic, sometimes with a sag that traps lint. That trapped lint is a fire risk, and it’s also why a dryer takes two cycles to finish a load. We clear the full run from the dryer connection to the exterior termination, remove the compacted lint, and confirm the vent is actually venting. Details on the safety side are on our Dryer Vent Cleaning in South Alamo page.
Air Duct Repair in South Alamo
In South Alamo, air duct repair usually means correcting decades of ad-hoc flex duct, retrofit connections and unsealed plenums rather than servicing a system that was built right the first time. Valley humidity and year-round runtime accelerate the damage, so a run that separates at the plenum is common rather than unusual. Our work here is Air Duct Repair in the full sense: find the failure, rebuild the connection properly, and re-seal the system so the repaired section stays repaired.
Ductwork Repair
Signs you need it
You need ductwork repair when a room never cools like the rest of the house, when the electric bill climbs through summer without a change in habits, or when you can see a flex run in the attic that has come loose from its collar.
What it costs in South Alamo
Ductwork repair in South Alamo typically runs $250 to $900, depending on how many connections are compromised and whether the plenum itself needs rebuilding.
How we do it
We isolate the affected run, reattach or replace the failed section of flex, seal the collar and plenum joints, then pressure-check the run so we know it’s delivering into the room rather than into the attic.
Air Duct Replacement
Signs you need it
Replacement makes more sense than repair when the flex is torn along its length, when the inner liner has collapsed, or when a run has been patched enough times that the next failure is predictable.
What it costs in South Alamo
Air duct replacement in South Alamo is typically $900 to $2,800 for the runs being replaced, and we set the exact figure in a written estimate after inspecting the attic.
How we do it
We measure the run, pull the failed duct, install new properly sized flex or hard duct with sealed connections, and verify airflow at the register before we close anything up.
What Air Duct Repair Costs in South Alamo
| Item | Typical range in South Alamo |
|---|---|
| Ductwork repair (seal and reattach a failed run) | $250 – $900 |
| Air duct replacement (affected runs) | $900 – $2,800 |
| Full duct system repair and re-seal | $1,500 – $3,500 |
Can you repair ductwork that was added room by room?
Yes. Add-on runs are what we see most in South Alamo, and they can be brought up to a sealed, balanced system. We map what’s there, replace the failing sections, and tie the rest together properly.
Why does one room in my South Alamo house stay warm?
Usually a disconnected or sagging flex run is dumping cooled air into the attic instead of the room. That’s a repair job, not a thermostat problem. Call (888) 971-5813 for an inspection.
Brands We Service in South Alamo
We work with Honeywell and Aprilaire whole-home air quality equipment, and we use Abatement Technologies filtration during cleaning so the process protects the air in the house rather than re-contaminating it. We don’t stock parts, so turnaround depends on what the repair needs. See our brands.

What South Alamo Customers Say
"They photographed every return and supply before starting and sent me the file afterward. No upsell to a sanitizing treatment I didn't need."
- Dana Quinn"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
- Kristen Fletcher"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
