Ductwork Repair in Lockhart

Ductwork repair in Lockhart almost always comes down to one thing we see constantly: rusted-out galvanized steel in dirt crawlspaces. The humid subtropical air that sits under a pier-and-beam house from May through September causes uninsulated metal ducts to sweat. Over decades, that sweat turns to rust pinholes. Eventually, the pinholes grow into gaps. Conditioned air leaks into the crawlspace, and humid outside air gets pulled into the return side every time the AC cycles.

Sealing Rust Pinholes and Failed Seams

For smaller rust-through sections, we cut out the failed steel, replace it with sealed aluminum, and rebalance the supply and return air so the system breathes properly again. Foil tape patches are not a repair. They are a temporary bandage that fails again within a season or two, and most Lockhart homes we visit have several already peeling.

Repairing Retrofitted Connections in Attics

In attic-mounted systems, especially in the 1960s-through-1990s brick ranches around Maple Street and Bois D’Arc Street, we find duct connections that were never sealed properly when the AC was retrofitted. Those gaps pull in insulation fibers, oak pollen, and the fine red clay dust that drifts off surrounding farm fields every time it is dry. Sealing them properly means opening the connection, applying the right mastic or tape, and confirming the airflow at the register before we leave.

A typical ductwork repair in Lockhart runs $350 to $650 per section, depending on access and how much failed material must come out. The written quote you get before we start is the price you pay. No per-vent charges, no surprise line items at the end.

Duct Replacement in Lockhart

Duct replacement in Lockhart is the right call when the rust is systemic, not localized. On older pier-and-beam homes with original 1940s-through-1960s galvanized duct runs, we often find rust along entire 10-foot sections, not just at a seam or a single pinhole. At that point, patching one more hole is throwing money at a duct system that has already failed.

Full Crawlspace Duct Replacement

When the crawlspace ductwork is beyond repair, we replace it with sealed aluminum or properly insulated flex, sized to the air handler and the home’s actual airflow needs. This is not a one-size-fits-all job. A 1930s Craftsman with two returns and a 2-ton system needs different duct sizing than a 1970s ranch with a single central return and a 3.5-ton unit. Full duct replacement under a Lockhart pier-and-beam home typically runs $2,200 to $3,400, depending on the number of runs, crawlspace height, and how much old material must be removed.

Replacing Crushed Flex in Attics

In newer Lockhart homes with flex duct in the attic, we replace crushed and sagging runs. Over time, insulation settles and compresses flex duct, starving the air handler of return air. That makes the blower work harder, raises energy bills, and can shorten the life of the compressor. When we replace a crushed run, we size it correctly and support it so it cannot sag again.

Duct replacement on a single failed run typically starts around $450 and goes up based on run length and attic or crawlspace access. Every replacement carries our written 365-Day Done Right Promise.

Trusted Brands We Service in Lockhart

We work on all major duct systems and air handlers, and we stock common repair parts so we are not making a Lockhart homeowner wait a week for a basic connector or damper. Our crews run professional-grade equipment from Rotobrush and Nikro for cleaning before and after repairs, and we specify air-quality products from Honeywell and Aprilaire when a Lockhart home needs filtration upgrades to handle the pollen and harvest dust that moves through these systems every spring and late summer.

Common Air Duct Repair Problems We See in Lockhart Homes

• Rust-through pinholes on galvanized steel. The humid air under a pier-and-beam crawlspace condenses on uninsulated metal ducts year-round. What starts as a few pinholes becomes a series of leaks that bleed conditioned air into the dirt.
• Leaky retrofitted connections in unconditioned attics. When central air was added to older Lockhart homes, the connections were often left unsealed. These gaps pull red clay dust and oak pollen directly into the return air stream.
• Collapsed flex runs under attic insulation. In Lockhart’s 1980s and 1990s subdivisions, flex duct is common. When insulation settles and compresses it, airflow drops and the air handler starves. The rooms at the end of the run get hot while the thermostat reads fine.
• Sagging or disconnected ducts in dirt crawlspaces. Pests, settling piers, and time all contribute. We find ducts that have separated completely, blowing conditioned air straight into the crawlspace for months before anyone notices the energy bills climbing.
