Ductwork & Airflow

Leaky ducts, uneven rooms, poor air quality. We find the problem and fix it right.

If the Rooms Aren't Right, Start With the Ducts

Most homeowners think about their furnace or AC when something goes wrong. The ducts are easy to overlook — they’re hidden in walls and ceilings, out of sight. But ductwork is how conditioned air actually gets to every room. If it’s leaking, undersized, or routed wrong, the whole system loses.

A system that’s working hard but not keeping up is often a duct problem, not an equipment problem. Fixing the equipment without fixing the ducts just means spending more money on the same result.

We fabricate custom duct components in-house. No waiting on catalog orders. If a job calls for something custom, we build it here and deliver it to the job. That’s what in-house sheet metal work looks like — the same shop running since 1994.

Ductwork Services

Duct Repair

Disconnected sections, collapsed flex duct, leaks at joints. We find where the system is losing air and fix it.

Duct Installation

New construction, room additions, full system replacements. We size and route ducts for the home, not a floor plan average.

Duct Sealing

Sealing leaks at joints and connections cuts energy losses and makes the whole system more efficient. Worth doing when we’re already in the attic or crawlspace.

Why It Matters

Why Ductwork Is Worth Getting Right

Efficiency

Up to 30% of the heating and cooling a system produces can disappear before it reaches the rooms. Leaky ducts are one of the most common reasons energy bills run higher than they should.

Comfort

A room that never heats up or cools down is usually a ductwork issue, not an equipment issue. Airflow that’s unbalanced or undersized can’t be fixed by turning up the thermostat.

Air Quality

Leaky ducts don’t just lose air — they pull it in. Dust, allergens, humidity from crawlspaces and attics. Sealed, well-maintained ductwork keeps what’s outside from getting inside.

Warning Signs

Signs Your Ductwork Needs Attention

Rooms that won’t heat or cool evenly

If some rooms are always too hot or too cold, the duct system isn’t delivering air where it needs to go.

Energy bills higher than they should be

A system that’s working hard but not keeping up is often losing air before it gets to the rooms.

More dust than usual

Dusty rooms or worsening allergies can mean ducts are pulling in air from attics, crawlspaces, or wall cavities.

Whistling or rattling from vents

Those sounds mean air is moving through gaps or connections that aren’t right.

Pest activity near ducts

Holes in ductwork give rodents and insects a place to get in. If you’re seeing signs of pests, get the ducts checked after you deal with the pest issue. We seal what they used to get in.

Visible duct damage

Collapsed flex duct, disconnected joints, or sections hanging loose in a crawlspace. If you can see it, call us.

System runs constantly but can’t keep up

Before replacing equipment, let us check whether the duct system is the real problem.

Common Questions About Ductwork

How do I know if my ducts are leaking?

The signs are usually comfort and cost — rooms that won’t stay at temperature, energy bills that seem too high, dust that keeps coming back. The only way to know for sure is a professional assessment. We can take a look and tell you what we find.

Can you add ductwork for a room addition?

Yes. We size new runs for the space, tie them into the existing system, and fabricate custom components in-house if the job calls for it. No waiting on special orders.

Does duct sealing actually save money?

For most homes, yes. If your ducts are leaking significantly, sealing them means the system doesn’t have to work as hard to hit the same temperatures. How much you save depends on how much was leaking to begin with — we can give you an honest read after we look at the system.

Do you do duct cleaning?

Yes. We clean ducts to remove built-up dust and debris, which improves air quality and helps the system run more efficiently.

What's the difference between duct repair and duct sealing?

Repair fixes structural problems — disconnected sections, collapsed flex duct, damaged components. Sealing addresses air leaks at joints and connections that aren’t fully airtight. Sometimes a job calls for both.
