Ductwork Repair — Book a Visit Today
We repair, seal and replace residential ductwork across Illinois, Indiana, Kentucky, Ohio, Tennessee and West Virginia, and the fastest way to start is a call so we can put eyes on the system. Ducts fail in ordinary ways. Tape lets go at the joints, flex runs sag and crush behind boxes in a crawlspace, and old trunk lines separate where they were never sealed properly. On a visit we walk the accessible runs in the basement, crawlspace or attic, check static pressure and airflow at the registers, and find where conditioned air is leaking into space you do not live in. Then we tell you plainly what needs sealing, what needs replacing, and what can wait. Call us and we will schedule a look.

The ductwork symptoms we hear most
- One bedroom never gets cool, no matter what I set the thermostat to Disconnected or crushed branch run, or a duct leaking most of its air before it reaches the register
- The registers barely blow anything even though the blower sounds like it is working hard High static pressure from undersized, collapsed or badly kinked ductwork
- My upstairs is ten degrees warmer than downstairs all summer Attic duct leakage and heat gain, or a trunk line with no real balance between floors
- The house is dusty a week after cleaning and the filter looks filthy fast Return-side leaks pulling crawlspace, attic or basement air into the system
- The basement is freezing in July and the living room never cools off Supply leaks dumping conditioned air into unconditioned or unused space
Whether you call it ductwork repair, air duct repair or duct sealing, the work is identical and so is the quote you approve first.
Safe things to check first
Worth a look before you call — sometimes it saves you the visit.
- 1Check that your thermostat is set to the mode you want and has fresh batteries, since a dead screen can look like a duct problem.
- 2Change or replace the air filter if it is grey and loaded. A clogged filter starves airflow and mimics a duct restriction.
- 3Walk the house and confirm supply and return vents are open and not blocked by furniture, rugs or boxes.
- 4Look at the breaker for the air handler or furnace and note whether it has tripped, then tell us what you found when you call.

How do you find a leaky duct?
We start with what you feel in the rooms, then measure airflow and static pressure and inspect the accessible runs in the basement, crawlspace or attic. Joints, boots and flex connections are where most leakage shows up, and we document what we find before quoting work.
Is duct sealing enough, or do I need replacement?
Sealing works when the duct is structurally sound and losing air at joints and seams. Replacement makes sense when flex is torn, insulation is soaked or fallen off, runs are crushed, or the duct was sized too small for the system in the first place.
Do you use tape or mastic?
We use mastic and proper mechanical fasteners on sheet metal seams, with foil tape where it belongs. Cloth duct tape dries out and lets go within a few years, which is why so much of the ductwork we open up is already leaking at old taped joints.
Will fixing my ducts help my energy use?
It usually helps, because air that leaks into a crawlspace or attic is air you paid to condition and never got to use. We will not put a number on it. What we can say is rooms get closer to even and the system runs less to keep up.
Can you work on ducts in a tight crawlspace or old shotgun house?
Yes. Much of the region we cover has crawlspaces, low basements and century-old houses with ductwork that was retrofitted decades after the house was built. We are used to working in tight runs and will tell you honestly if a section cannot be reached.
How long does ductwork repair take?
Sealing accessible joints on a normal system is often a single visit. Replacing a trunk line or rebuilding several branch runs can take a day or more, depending on access. We give you a scope and a timeline before anyone starts cutting metal.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads. That short conversation tells us whether you need a visit today or tomorrow morning.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and ducts, and the equipment itself. We find the actual cause instead of swapping parts and hoping the noise goes away.
- Step 3
You decide before we work
We explain what failed, what the repair involves, and what we would do if it were our own house. Nothing gets replaced until you say go. Then we test the system before leaving.

Why homeowners call us
- Old houses and new onesWe are used to century-old homes with retrofitted ductwork and 1970s subdivisions with original returns. Tight crawl spaces, low basement headroom and odd attic runs are normal parts of the day for us, not surprises that stall the job.
- Built for the swingsHumid summers push AC systems hard and January freezes expose weak igniters and cracked flues. We repair for both extremes across the region, so the fix holds when the weather turns instead of failing the first hard week.
- Air conditioning and heating bothAir conditioner repair in July, heating repair in January, and the IAQ and airflow problems that hide in between. One crew that knows how your cooling and heating share the same blower and the same duct system.
- Plain talk, no pressureWe tell you when a repair makes sense and when replacement is the honest answer. No scare tactics about your BTU load, no upsell scripts. You get the condition of the system and a clear next step.
