That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

We know the streets here. From the brick ranches along Main Street to the post-war homes near the College Park Historic District, our technicians have scoped, sealed, and repaired ductwork in this city since 2013. The original fiberglass-lined metal trunks and first-generation flex duct runs we encounter aren’t theoretical - they’re what we photographed yesterday, what we’ll photograph tomorrow. Every job concludes with a Documented Photo Record of every duct run, delivered to you as a standard deliverable, not an upsell.
Why CleanRun Air Duct Cleaning Atlanta Is College Park’s Preferred Duct Repair & Sealing Company
Our reputation in College Park was built on showing, not telling. When a homeowner in the Historic District brings us a competitor’s $79 coupon estimate, we provide a Free Second Opinion - our written price next to theirs, line by line, under Haven Standard Clause 1. No exceptions.
Customers here research before they call. They want to know what equipment enters their home, what credentials the crew carries, and what they’ll hold in their hands when the truck leaves. We answer with specifics: background-checked, uniformed technicians operating under Haven Standard Clause 3: Verified Crews; professional-grade Rotobrush and Nikro equipment; and a 365-Day Done Right Promise backed in writing on every job, not buried in a policy manual.
Dispatch and scheduling are coordinated from our Atlanta office, but crews serve College Park locally. That matters when a disconnected trunk joint is blowing conditioned air into a crawlspace and the master bedroom won’t hold temperature. We’re familiar with the approach-corridor noise, the jet-exhaust residue that darkens roof shingles, and what that same residue does inside ductwork over decades. Local knowledge changes what we look for.
Tomas Reyes, who leads CleanRun, established the Documented Photo Record practice in 2013 and has maintained it across 52,000+ homes. In College Park, that means customers see the actual condition of their duct runs - the disconnected joints, the degraded liner, the aviation soot coating - before any sealing work begins.
Our Duct Repair & Sealing Services in College Park
Duct Sealing
College Park’s original ranch homes were built with metal trunk-and-branch systems sealed with mastic or foil tape that has cycled through forty years of Atlanta’s April-to-October condensation season. The seals crack. Air leaks into wall cavities and crawlspaces before it reaches the registers. Our Duct Repair & Sealing team pressure-tests the system, identifies leak paths with smoke pencil or theatrical fog, and reseals joints with fresh mastic and mechanical fasteners. A typical duct sealing job in College Park runs $280-$450 for a single-system home.
Flex Duct Repair
The flex duct installed during 1960s and 1970s HVAC upgrades in College Park has softened in Georgia’s crawlspace humidity. The inner core collapses. The insulation jacket sags. We find crushed runs behind the College Park Historic District’s brick facades that have been leaking 30% of conditioned air for years. Where the flex is structurally intact, we repair and support the run with proper hangers and replace damaged sections with new R-8 insulated flex. When the core is degraded, we replace the full run. Flex duct repair in College Park typically ranges $180-$340 per run; full replacement runs $220-$420 per run depending on crawlspace access.
Metal Duct Repair
The galvanized steel trunks in College Park’s older homes corrode at joints, separate at seams, and - in homes under Hartsfield-Jackson’s flight paths - accumulate a layer of greasy aviation soot that accelerates surface degradation. We repair separated seams with sheet-metal screws and mastic, replace corroded sections with matching gauge steel, and reconnect trunk joints that have blown apart from decades of pressure cycling. Metal duct repair in College Park generally falls between $320-$580 depending on accessibility and extent of corrosion.
Duct Insulation
Original fiberglass duct insulation in College Park homes has absorbed condensation, airport particulate, and pollen for decades. Once the vapor barrier is compromised, the insulation traps moisture against the metal trunk. We remove degraded insulation, clean the trunk surface, and re-wrap with foil-faced duct insulation rated for the pressure and temperature of modern HVAC systems. Duct insulation work in College Park typically costs $260-$480 for a standard ranch layout.
Mastic Sealant Application
Mastic is the workhorse of durable duct sealing - a fiber-reinforced, water-based compound that remains flexible after curing. In College Park, we apply mastic to every joint, seam, and penetration after mechanical fastening. The foil tape that held for fifteen years won’t hold for fifteen more; mastic, properly applied, does. This is standard on every sealing job we perform, not an upgrade.
Air Leak Repair
Air leaks in College Park homes cluster at the air handler plenum, trunk takeoffs, and register boot connections. We repair these with a combination of mechanical fastening, mastic, and - where code requires - fire-rated sealant at penetrations. The goal is simple: what the air handler produces reaches the rooms, not the crawlspace.

Common Duct Repair & Sealing Problems We See in College Park Homes
- Disconnected trunk joints from decades-old AC replacements. In the College Park Historic District, we regularly find metal trunk joints that separated during a 1980s or 1990s equipment changeout and were never properly reconnected. Conditioned air blows into the crawlspace; the bedroom above never reaches setpoint.
- Degraded fiberglass duct liner shedding particulate. Thirty-plus-year-old liner in College Park’s 1950s-1970s homes becomes saturated with airport soot and humidity, then begins to break down. Cleaning removes loose material; sealing or encapsulation stops the shedding.
- Crushed flex duct in humid crawlspaces. Georgia’s crawlspace humidity softens the wire helix of old flex duct. The run collapses under its own weight or gets crushed by storage items. Airflow drops; rooms go stale.
- Failed mastic and tape seals from condensation cycling. Atlanta’s intensive AC season creates repeated condensation inside ductwork. Seals that held for years crack and peel, opening leak paths that show up as uneven temperatures room to room.

FAQs - Duct Repair & Sealing in College Park
You’ll likely find disconnected trunk joints from a prior AC replacement, degraded fiberglass liner shedding into the airstream, and mastic seals that have cracked after forty years of condensation cycles. Our camera inspection will show you exactly what condition your duct runs are in, and the written price will reflect only what needs to be done to make the system whole. Call (470) 495-9370 for a free estimate.
College Park sits directly under Hartsfield-Jackson’s approach and departure corridors, so your ductwork accumulates a greasy, dark carbon soot signature from jet exhaust - identifiably different from the tan dust typical of Atlanta’s northern suburbs. That aviation particulate accelerates liner degradation and changes what cleaning and sealing need to address. Your cousin’s ducts in Marietta don’t face this specific contamination layer.
Cleaning removes debris; sealing prevents it from returning and stops conditioned air from leaking out. In College Park’s older homes, we regularly find that cleaning alone leaves disconnected joints and cracked mastic still leaking air. The two services address different problems. If your cleaning contractor didn’t pressure-test the system or photograph the joints, you don’t yet know whether sealing is needed. We include that assessment in every visit.
Repair is absolutely on the table when the inner core is intact and the wire helix retains its shape. We support the run with proper hangers, replace damaged jacket sections, and seal connections. Replacement becomes necessary when the core has collapsed, the helix is corroded, or the insulation is saturated. Our camera inspection shows you which category your runs fall into before you commit to either approach. Call (470) 495-9370 for an exact assessment.
We treat the air distribution system as a single pressure boundary. The air handler plenum is sealed to the trunk; the trunk takeoffs are sealed to the branch runs; the branch runs are sealed to the register boots. In College Park’s ranch homes, the weak points are typically the trunk joints and the register boot connections - the long straight runs of metal duct usually hold up better than the transition points. Our written scope specifies exactly which components are included and which were found intact.
