Signs Your Ductwork Needs Repair or Replacement
Ductwork is usually the problem when the equipment checks out but the house still heats or cools unevenly. ENERGY STAR estimates that in a typical home, 20 to 30 percent of the air moving through the ducts is lost to leaks, holes and poorly installed ducts. Watch for these signs:
- One or two rooms that never reach the thermostat setting
- Weak airflow at some registers while others blow hard
- Whistling, rattling or popping from the ducts when the system starts
- Ducts that are crushed, sagging, torn or disconnected in the attic or crawlspace
- Ducts that sweat or drip in summer
- A new system running on ductwork sized for the old one
- An addition, finished attic or bonus room the ducts don’t reach
How We Design and Build Your Ductwork
Here’s how a duct job runs:
- Look and measure. At your free estimate we check the equipment, the existing ducts and how air reaches each room.
- Plan the layout. We lay out the runs to fit the house and the equipment.
- Build it in our shop. Our fabricators cut and form the ducts and fittings to the measurements from your house.
- Install and seal. We hang, connect and seal the new ductwork, and we pull the permit the job needs.
What Does New Ductwork Cost?
The cost of ductwork depends on how much of it changes, so we price it after a free in-home estimate rather than from a chart. The other factors are how easy the ducts are to reach, the number of rooms served, how many custom fittings the layout needs, and whether new equipment goes in at the same time. You get the price before work begins, with a clear list of what’s included and no pressure.
For a repair visit, the diagnostic fee is $135 on weekdays, $195 after hours and on weekends, and $155 after hours for maintenance agreement members. It applies toward the repair.
Ductwork for New Homes, Additions and Businesses
We design and build duct systems for new homes, additions, finished attics and bonus rooms. Our team can size the heating and cooling system and the ducts together, build the runs in our shop and install them at rough-in. If you’re building or adding on, call while the plans are still on paper.
Our shop also fabricates ductwork for other businesses.

Do You Need a Permit for New Ductwork in Chesterfield County?
Usually, yes. Chesterfield County requires a mechanical permit to install ductwork or to replace a furnace’s ductwork, and adding three or more ducts to a forced-air system calls for a rough-in inspection and a final inspection. The rough-in comes after the ducts are in and before insulation and drywall go up, so on an addition, a finished attic or a room over the garage, the duct work has to be scheduled ahead of the walls. Finishing the space needs its own building permit. We pull the mechanical permit for our work and schedule the inspections.
We build and install ductwork from our Midlothian shop across Chesterfield County, including Chester, and in Powhatan.
Ductwork & Metal Fabrication FAQs
Should I replace my ductwork when I replace my heating and cooling system?
Not always. Ducts that are sealed, in good shape and sized for the new system can stay. Leaking, crushed or undersized ducts hold back what new equipment can deliver, so those sections should be fixed or replaced with it. We check the ducts at every air conditioning installation and furnace installation estimate and tell you which sections need work.
Can you repair ductwork instead of replacing it?
Often, yes. A disconnected run, a crushed section or a leaking joint can usually be fixed on its own. Replacement makes sense when much of the system is damaged, undersized or failing at the seams. When both are reasonable, we price both.
Can new ductwork help with dust and humidity?
It helps with dust. A leaky return duct in an attic or crawlspace pulls in dust, insulation fibers and damp air and sends them through the house, and sealed ducts stop that. For humidity itself, a whole-home dehumidifier does the work; see our indoor air quality options.
Is custom ductwork worth it over standard ductwork?
Where standard sizes don’t fit, yes: odd-shaped trunks, tight attics and crawlspaces, and transitions between new equipment and older ducts. Standard pieces cost less when they fit. Most duct systems combine both, and our shop builds the custom ones.
