Upper Arlington’s homes aren’t like the rest of Columbus. The gravity-furnace conversions that heated these neighborhoods from the 1930s through the 1960s left behind ductwork systems that most generalist HVAC crews simply aren’t equipped to handle properly. Our Duct Repair & Sealing team knows these streets and these houses. Paul Torres shows up personally as lead technician on your job, bringing 8 years of focused air duct specialization and the professional-grade Rotobrush and Nikro systems needed for oversized plenum trunks that standard equipment can’t touch. When you’re dealing with 60-year-old galvanized steel, unsealed joints, and the humidity problems that come with living near the Olentangy floodplain, you need someone who’s done this exact work in Upper Arlington before — not a franchise crew learning your house on the fly.

Why Legacy Air Duct Cleaning Columbus Is Upper Arlington’s Preferred Duct Repair & Sealing Company

We’ve built our reputation one Upper Arlington home at a time. Nearly 1,000 customers have reviewed our work at a 4.7-star rating, and many of those reviews come from repeat visits to the same Tudor Revival and Colonial neighborhoods where word travels fast between neighbors on streets like Barrington Road and Ridgeview Middle School’s surrounding blocks.

Paul Torres doesn’t delegate your job to a rotating crew. He shows up personally as lead technician, which means the most experienced person in our company is the one crawling through your crawl space, inspecting your plenum trunks, and applying mastic sealant to joints that haven’t been touched since the Eisenhower administration. That’s a level of accountability you won’t find with generalist handymen or franchise operations that treat duct repair as an add-on service.

Our response time to Upper Arlington averages under 30 minutes during business hours because we’re based in Columbus and know these roads. We don’t need GPS to find the split-levels off Zollinger Road or the Cape Cods near Thompson Park. That local familiarity translates to faster diagnostics and more accurate estimates — we’re not guessing at what we’ll find behind your walls.

Eight years doing one thing well means we’ve encountered virtually every duct configuration Upper Arlington’s housing stock can produce. The asbestos-wrapped supply plenums in pre-1960s homes, the irregularly routed galvanized lines from gravity conversions, the humidity-compromised flex duct in additions — we’ve sealed and repaired them all.

Our Duct Repair & Sealing Services in Upper Arlington

Mastic Sealant Application

Mastic sealant is our go-to solution for Upper Arlington’s unsealed metal joints, and it’s particularly critical for gravity-conversion systems where decades of thermal expansion have opened gaps at trunk-line connections. We apply fiberglass-reinforced mastic by hand to every accessible joint, creating a permanent flexible seal that outlasts foil tape by decades. In Upper Arlington’s older homes, this process takes longer than standard suburban jobs because we’re working with 16–20 inch wide plenum trunks that require thorough coverage across oversized surface areas. The mastic cures to a hard, durable finish that withstands the humidity cycling these river-adjacent homes experience through Ohio’s muggy summers.

Metal Duct Repair

The galvanized steel trunk lines in Upper Arlington’s 1930s–1960s housing stock weren’t designed for forced-air systems, and after 60–80 years they’re showing it. We repair separated seams, corroded sections, and damaged take-off collars using professional-grade sheet metal techniques and proper mechanical fastening — not duct tape, not temporary patches. When we encounter the oversized rectangular trunks common along Tremont Road and Cambridge Boulevard, we fabricate custom transition pieces rather than forcing incompatible fittings. These repairs restore structural integrity to systems that standard residential cleaning equipment often can’t even access properly.

Flex Duct Repair & Replacement

Many Upper Arlington homeowners added flex duct runs during basement finishing projects or kitchen renovations, and these newer sections often fail first — crushed by storage items, chewed by rodents, or degraded by the temperature fluctuations in unconditioned crawl spaces. We replace damaged flex with properly sized, insulated runs that match your system’s static pressure requirements. Unlike the original metal trunks, flex duct demands precise length and support calculations; too long or unsupported, and you’ll get sagging sections that trap debris and reduce airflow to second-floor bedrooms.

Duct Insulation

Upper Arlington’s humid summers and cold winters punish uninsulated ductwork in attics and crawl spaces. We install formaldehyde-free fiberglass duct wrap or closed-cell foam insulation depending on your system’s configuration and accessibility, with particular attention to supply plenums that pass through unconditioned spaces. Proper insulation doesn’t just save energy — in this climate, it prevents the condensation that feeds mold growth inside your ductwork, especially critical for homes near the Olentangy where baseline humidity already runs higher than Columbus’s eastern suburbs.

Trusted Brands We Service in Upper Arlington

We work with the equipment and components that professional IAQ contractors trust: Rotobrush and Nikro mechanical agitation systems for thorough cleaning access, Honeywell and Aprilaire media filters and whole-house humidifier components, plus Abatement Technologies HEPA filtration and Guardsman protective products. For Upper Arlington’s vintage systems, we stock a range of sheet metal fittings, mastic compounds, and insulation materials sized for larger-diameter trunk lines — parts that many standard HVAC suppliers don’t keep on hand because they’re outside modern residential norms. That inventory means faster turnaround on your repair, fewer return visits, and a system that actually performs after we’re done.

Common Duct Repair & Sealing Problems We See in Upper Arlington Homes

• Oversized plenum trunks from gravity-furnace conversions — These 16–20 inch wide rectangular channels are too large for standard flex-line whip tools, leaving decades of compacted debris and unsealed leaks untouched by conventional cleaning crews. We bring larger-diameter Rotobrush equipment and longer cleaning windows to address what others simply can’t reach.
• Asbestos-wrapped supply plenums in pre-1960s homes — The Cape Cods and early Tudors near Thompson Park often feature original asbestos insulation on ductwork that complicates any sealing or repair work. We identify these materials before work begins and coordinate with certified abatement specialists when disturbance is unavoidable — never cutting corners on safety protocols.
• Humidity-driven mold in river-adjacent microclimates — Upper Arlington’s position next to the Olentangy floodplain, combined with Central Ohio’s muggy summers, creates indoor humidity loads that exceed what poorly sealed ductwork can handle. Return-air intakes under the city’s dense tree canopy pull in leaf mold and pollen that colonize damp duct interiors, spreading spores through every room.
• Unsealed joints at gravity-conversion transitions — The original furnace removals left irregular connection points between old trunk lines and new forced-air equipment, often sealed with failing foil tape or nothing at all. These leaks pressurize crawl spaces and wall cavities instead of delivering conditioned air to your rooms, wasting energy and creating pressure differentials that pull in unfiltered outside air.
