Call (361) 326-5060

We know Savannah’s streets well. Our crews dispatch from the Dallas-Fort Worth office and run scheduled routes through the master-planned sections off FM 423 and Teel Parkway. If you’re near Savannah Parkway or tucked into the neighborhoods around Oakmont Boulevard, we’re familiar with your attic layout before we arrive. The flexible duct runs common in Savannah’s 2000s-era construction sag in our North Texas heat, pull apart at seams, and bleed conditioned air into spaces that don’t need cooling. That shows up as uneven temperatures between rooms and summer electric bills that climb without explanation. We’ve sealed ducts in enough Savannah homes to recognize the pattern quickly.

Duct Insulation in Savannah

Duct Insulation in Savannah addresses a problem specific to our market: flexible ductwork running through unconditioned attics that regularly reach 140°F in July and drop below freezing in January. When the insulation jacket on flex duct compresses, degrades, or was undersized from the start, your HVAC system loses thermal energy through the duct wall itself. We replace or supplement insulation with fiberglass wraps or foil-faced products rated for attic exposure, then seal every penetration point to prevent the humid outside air from reaching the conditioned airstream.

When Attic Heat Overwhelms the Duct

In Savannah’s tightly built, energy-efficient homes, the attic becomes a thermal bottleneck. Cool air leaving your coil can warm by 5 – 10 degrees before reaching the vent if duct insulation is compromised. We measure supply air temperature at the unit and at the register to document the loss, then specify insulation that restores the original R-value or better.

Condensation and Mold Prevention

North Texas humidity produces condensation on under-insulated cool ducts during shoulder seasons. That moisture feeds mold and dust mites in the attic space and can migrate into the airstream. Proper insulation with intact vapor barriers breaks the condensation cycle and protects indoor air quality.

HVAC Duct Sealing in Savannah

HVAC Duct Sealing in Savannah focuses on the pressure-tested closure of leaks in the supply and return plenums, trunk lines, and branch runs that distribute conditioned air throughout your home. We pressurize the system, identify leakage points with smoke pencils or digital manometers, then apply mastic sealant and UL-181-rated metal tape at every failure point. After sealing, we retest to verify the improvement. A typical Savannah home with accessible attic ductwork runs $400 – $700 for standard sealing; systems requiring extensive access work or multiple return plenum modifications can reach $800 – $900.

Pressure Testing Before and After

We measure duct leakage in CFM25, cubic feet per minute at 25 Pascals of pressure, before we start and after we finish. Savannah homeowners see the numbers in writing. If the post-seal test doesn’t show meaningful improvement, we keep working until it does.

Reconnection of Separated Flex Runs

Builder-grade flex duct in Savannah’s 2000s construction often pulls away from collars or sags until it kinks. We support the duct with proper straps, reconnect with mechanical fasteners, then seal the joint with mastic. The repair lasts because we don’t rely on tape alone.

Trusted Brands We Service in Savannah

We stock filtration and sealing products from Honeywell, Aprilaire, and Abatement Technologies for Savannah customers, which means no waiting on shipped parts for most jobs. Our equipment roster includes Nikro negative-air machines and Rotobrush rotary brush systems for the cleaning work that often accompanies sealing. When we seal your Savannah home’s ducts, we use professional-grade mastic and metal-backed tapes rated for temperature cycling in North Texas attics, not the hardware-store foil tape that degrades in two seasons. If your system needs a filtration upgrade after sealing, we carry Honeywell and Aprilaire media cabinets and Guardsman UV options with fast turnaround from our Dallas-Fort Worth inventory.

Common Duct Sealing Problems We See in Savannah Homes

• Sagging flex duct at the plenum connection. Savannah’s attic heat softens the vinyl jacket on builder-grade flex, causing the duct to pull away from the air handler collar. We find this in nearly every home built between 2004 and 2012 off FM 423, and it wastes 15 – 20% of conditioned air before it reaches the vent.
• Kinked branch runs over hallway ceilings. The long, unsupported flex runs common in Savannah’s two-story plans sag between trusses until they pinch flat. Airflow drops to a whisper in the affected room, and the homeowner cranks the thermostat down to compensate.
• Leaky return air pathways pulling attic air. Tight construction in Savannah means returns are often framed in wall cavities or soffits that aren’t fully sealed. We pressurize the return side and find it drawing 90°F attic air through gaps around the chase, mixing dust and insulation fibers into the air you breathe.
• Condensation damage at unsealed boots. Where the duct meets the ceiling register, missing or degraded mastic lets humid attic air contact the cool metal boot. Rust forms, ceiling stains appear, and the boot eventually separates from the drywall. We seal the penetration and replace corroded hardware.
