Duct Replacement in Terrell Hills

Duct Replacement in Terrell Hills is what we recommend when a section of original galvanized duct has rusted through, collapsed, or separated beyond what a patch can honestly fix. On a 1930s pier-and-beam home, that often means replacing a run under the floor where the metal has been sweating for decades. The job involves removing the failed section, fabricating a properly sized replacement, sealing every joint with mastic, and testing airflow before we leave. Whole-system replacement in Terrell Hills typically runs $2,800 to $6,500 depending on the length of the runs and how many registers are fed. Partial replacement, like a single failed return or a 20-foot supply run, usually lands between $650 and $1,400.

When Original Ductwork Has Reached Its Limit

Galvanized ductwork from the 1920s through the 1950s doesn’t fail all at once. It rusts at the seams first, usually where humidity collects in low spots under the pier-and-beam. We tell Terrell Hills homeowners to replace rather than repair when the metal has thinned enough that a patch would simply move the failure point a few feet down the run. You’ll see it in rising utility bills, rooms that never reach temperature, and that musty smell that comes back weeks after every cleaning.

Matching New Ducts to Old Homes

Homes in Terrell Hills were often built with one system, then added onto in the 1960s or 1970s when a new wing went up. The additions rarely got properly sized ductwork. When we replace a section, we calculate the static pressure for the entire run so the new duct actually matches what your blower can handle. That’s the difference between a repair that lasts and one that strangles airflow from day one.

Ductwork Installation in Terrell Hills

Ductwork Installation in Terrell Hills usually means one of two things: running new supply and return runs for a newly added room, or replacing an entire system when the original has finally given out. On larger homes here, that’s a significant job because the buildings sit on pier-and-beam foundations with long, winding runs under the floor. A full installation for a 3,500-square-foot Terrell Hills home typically runs $7,000 to $14,000, while a single-room addition with a new supply and return usually lands between $1,800 and $3,400. We give you a line-item written price before work starts, so you see exactly what you’re paying for.

Proper Sealing for Pier-and-Beam Homes

Under the floor of a Terrell Hills house, there’s no attic insulation protecting your ductwork. The metal sits in whatever humidity the crawlspace holds. New ductwork has to be sealed with mastic at every joint and supported so it doesn’t sag into the damp. We run a negative-pressure test after installation to confirm the system isn’t pulling air from under the house. If it leaks, we fix it before we call the job done.

Multi-System Homes Need Clear Pricing

Many of the larger homes in Terrell Hills have two or three separate HVAC systems, one per floor or per wing. That means ductwork installation isn’t one flat number. We price each system separately so you know exactly what the upstairs system costs versus the original downstairs runs. A house with three systems might see per-system pricing of $2,400 to $4,800 each depending on access and run length. One flat rate for the whole house hides what you’re actually paying for.

Common Air Duct Repair Problems We See in Terrell Hills Homes

• Rusted-through galvanized supply runs under pier-and-beam foundations. Original 1930s metal sits in the crawlspace humidity for decades and eventually rusts at the seams. We find this on nearly every pre-1950 home we open up.
• Separated duct joints pulling in pollen and dust. On Eldon, we diagnosed a 1938 home where the original supply ducts had separated under the house, pulling cedar dust and live oak pollen straight into the returns. Our crew used a camera inspection to map the break, then performed a source removal repair with HEPA filtration to seal the run and restore airflow without disturbing the foundation.
• Mismatched sizing from later additions. When a Terrell Hills home got a new wing in the 1960s or 1970s, the contractor often tied the new ductwork into the old system without recalculating airflow. That creates negative pressure zones where the largest bedroom never cools and starts pulling unconditioned attic air into the system.
• Floor registers clogged with live oak pollen and cedar dust. Homes along Eldon and Garraty with original floor registers collect a thick layer of pollen every spring. It chokes the air handler’s efficiency and overworks blower motors, especially on multi-system homes where one unit is trying to carry an entire wing.
