Bell Heating & AirDuctwork repair and sealing in College Station and the Brazos Valley.
When rooms are hot or cold, dust complaints are constant, and utility bills feel high for the system size — the problem is usually ductwork, not the AC or furnace. Static pressure testing tells us where the airflow is failing, and sealing or resizing fixes what equipment swaps alone can't.

Common reasons homeowners call us about ductwork.
- Hot or cold spots that the AC/furnace doesn't fix
- High utility bills relative to system size
- Excessive dust everywhere — usually a return-side leak
- Whistling, banging, or wheezing from registers
- Short cycling without any equipment failure
- Humidity stays high even with the AC running
Our ductwork process.
Static pressure test
We measure airflow at multiple points and identify where the system is choking. Most companies skip this step.
Written scope & estimate
Specific runs, specific fixes, specific prices. No 'we'll figure it out' line items.
Repair completed
Most ductwork repairs take 1 day. Larger redesigns 2–3 days.
Post-fix verification
We re-measure airflow and pressure after the fix to confirm the problem is solved.
