Air Duct Repair & Installation in San Antonio
Repair of leaking, crushed, or disconnected ducts, and new duct installation.
- Free estimates
- Seniors & military discounts
- Locally owned & operated
A room that never cools down, or an attic that gets cold air it shouldn't, often means a duct is leaking, crushed, or has come loose.
Repair or replace?
We inspect your duct system first, including a camera inspection where it helps, then tell you what we found. Small leaks and loose connections can usually be repaired. Ducts that are crushed, badly deteriorated, or undersized may need replacing. Either way, you get a free estimate before any work starts.
Common duct problems we fix
- Leaking seams and joints
- Crushed or kinked flex duct
- Disconnected runs in the attic
- Old or deteriorated duct lines
- New duct runs for additions and remodels
How we find and fix duct leaks in San Antonio homes
Most San Antonio ductwork is flex duct running through a hot attic, and heat, age and foot traffic take a toll. A joint that pulled apart in July can dump cooled air into the attic for months before anyone notices anything except a warm bedroom and a higher bill. We start with a camera inspection of the runs, then check the plenum connections, boots and seams. Small leaks are sealed with mastic, disconnected runs are reconnected and strapped, and crushed or deteriorated sections are replaced with new insulated duct.
What a duct repair visit looks like
- Camera inspection and airflow check at every vent
- A written price before any work starts
- Repairs finished the same visit whenever the parts are on the truck
Questions we hear
How do I know if my ducts are leaking?
Rooms that never reach temperature, dust that comes back fast after cleaning, high bills, or a whistling sound at the vents. A camera inspection confirms it.
Can you fix a duct that came apart in the attic?
Yes. Disconnected, crushed and torn ducts are the most common repairs we do, usually in one visit.
Do you install new ductwork?
Yes, for additions, remodels and replacements. We size and route the new runs and give you a free estimate first.
Do you offer discounts on repairs?
Yes. Seniors and military discounts apply to every service, repairs included.
How much does air duct repair cost?
Small repairs such as reconnecting a run or sealing a joint are inexpensive. Replacing crushed or deteriorated sections costs more. The estimate is free and you approve the price first.
