Homeowners' pick for heating and cooling across central Kentucky and the Bluegrass

Duct Sealing

Duct sealing closes the leaks in your duct system so the air your furnace or AC makes actually reaches your rooms. We do this work for homeowners across Georgia, Indiana, Kentucky, Ohio, Tennessee and West Virginia. If some rooms never get comfortable, if your system runs and runs, or if you see dust streaking out of a register, call us and we will come look at the ducts before anyone talks about replacing equipment. Bring us a list of the rooms that bother you most and we will start there.

Whether you call it duct sealing or air duct repair, the work is identical and so is the quote you approve first.

What duct sealing actually involves

We start in the crawlspace, attic or basement where the ducts run and find where air is escaping. Joints pull apart, old cloth tape gives up, boot connections at the floor loosen, and plenum seams open. We seal those points with mastic and mechanical fasteners, then insulate where the duct passes through unconditioned space. In older farmhouses where ductwork was added long after the house was framed, we often find long runs held together with little more than gravity and hope. Those get rebuilt as we go.

What we check and what we install

We check static pressure, register temperatures, and airflow at the rooms you complained about. We look at return sizing, because a system starved for return air behaves like a leaky one. Then we seal supply and return seams, replace crushed flex, add proper takeoffs where branches were cut in sloppily, and close panning or open cavity returns that pull air from a crawlspace. On propane and dual-fuel setups we pay extra attention to the plenum area, since leaks there waste the most heat.

How we decide sealing is the right call

Sealing makes sense when the equipment tests out fine but the air is not arriving. Uneven room temperatures, high dust levels, whistling near registers, and a system that never seems to satisfy the thermostat all point at the ducts. If the duct is rusted through, sized wrong for the load, or buried under insulation and inaccessible, we will say so and price repair or replacement of that section instead. We would rather tell you the truth than seal a duct that needs replacing.

Duct Sealing — quick answers

Will duct sealing fix one room that is always cold?

Often yes. A disconnected boot or a leaking branch line is a common cause. We measure airflow at that register first, because the fix might also be a damper adjustment or a duct that is undersized.

How long does the work take?

Most homes take part of a day once we have access. Tight crawlspaces, long farmhouse runs, or ducts that need rebuilding rather than sealing will add time. We give you the scope before we start.

Does sealing ducts help with dust?

It helps when the leaks are on the return side, since those pull dust, insulation fibers and crawlspace air into the system. Sealing returns and pairing that with a properly fitted filter usually makes a noticeable difference.

How it works

  1. Step 1

    Tell us the symptom

    Call or fill in the quote form and describe what changed. Warm air, no air, a smell, a noise, a breaker that keeps tripping. That detail tells us what parts to bring along.

  2. Step 2

    We diagnose on site

    We check the thermostat, the electrical side, airflow and the equipment itself before we quote anything. If the problem sits in the ductwork rather than the unit, we say so plainly.

  3. Step 3

    We repair and explain

    Most air conditioning repair and heating repair work finishes in one visit. We show you the failed part, explain what caused it, and tell you what to watch for next season.

Why homeowners call us

  • Propane and dual fuelPlenty of homes in our service area run propane heat or a dual fuel setup with a heat pump. We know how those systems switch over and why a bad changeover setting can leave you cold and burning fuel.
  • Older houses, added ductworkFarmhouses often got ducts decades after they were built, run through crawl spaces and attics. When the equipment tests fine but rooms still fight each other, we look at the duct runs and static pressure.
  • Repair before replacementA failed capacitor, a cracked wire, a clogged drain or a bad control board is a repair, not a new system. We tell you when the equipment is genuinely finished and when it is not.
  • Plain talk on the phoneWe ask what the thermostat reads, whether the outdoor unit is spinning, and when it last worked normally. That two minute conversation often shortens the visit and keeps the repair cost down.
  • All major brands, gas & electricCarrier, Trane, Lennox, Goodman, Rheem, York and more, as an independent company.
  • Straight answersIf a system is not worth repairing, we say so, often right on the phone.
