Duct Sealing in Old Fig Garden - Tested First, Written Price Second

Fast, Reliable Duct Sealing Across Old Fig Garden

If your upstairs bedrooms never cool off in July or your PG&E bill spikes every summer despite a new AC unit, the problem is probably not your equipment. It’s the gaps, separations, and deteriorated seals in your ductwork letting conditioned air escape into your attic or crawlspace. In Old Fig Garden, where most homes were built between the 1920s and 1950s, we’ve found that unsealed ducts waste 20 to 30 percent of the air homeowners pay to heat and cool. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews work out of our Fresno, Central Valley office to reach Old Fig Garden properties quickly.

Why Hollis Air Duct Cleaning Is Old Fig Garden’s Preferred Duct Sealing Company

We’ve been sealing ducts in the San Joaquin Valley since 2004, and Old Fig Garden’s estate homes are some of the most rewarding jobs we take. The neighborhood’s custom ranchers and Spanish Revival properties weren’t built for modern forced-air systems, so retrofit sealing requires patience and familiarity with plaster-lath walls, deep attics, and the oddball duct transitions installers added decades ago. Roy Castellanos, who leads Hollis Air Duct Cleaning, trains our technicians on exactly these conditions.

Our customers in Old Fig Garden tell us the same thing: they called us because the last company gave a phone quote that doubled once the van arrived. That doesn’t happen here. We put the price in writing before we touch anything, and that written price is covered by our 365-Day Done Right Promise. If the seal fails within a year, we come back and make it right at no charge, including a free second visit. Our phones are answered by a live person 24 hours a day, seven days a week, and our technicians arrive background-checked, uniformed, and inside the quoted window.

HVAC Duct Sealing in Old Fig Garden

HVAC Duct Sealing in Old Fig Garden means closing every leak point in your forced-air system so the air you paid to condition actually reaches the rooms where you live. Most Old Fig Garden homes have supply ducts running through uninsulated attics that hit 140 degrees in August, or through crawlspaces where tule fog moisture corrodes metal seams. When those ducts leak, you’re paying to cool your attic or heat your crawlspace. A typical whole-house duct sealing job in Old Fig Garden runs $1,200 to $2,800 depending on system size, attic accessibility, and how many original duct sections need individual attention.

Attic Duct Sealing

Old Fig Garden’s large unfinished attics are a blessing for storage and a curse for ductwork. Original gravity-furnace chases were never designed for pressurized air, and the retrofit flex duct or rigid metal added in the 1970s often pulls apart at seams. We use mastic sealant and mechanical fasteners rated for temperature swings, not tape that dries and falls off in two seasons.

Crawlspace Duct Sealing

The mid-century infill homes near Van Ness Boulevard and the Fig Garden Swim & Racquet Club sometimes push duct runs through tight, low-clearance crawlspaces rather than attics. These spaces collect moisture from winter fog and spring irrigation runoff, corroding metal and loosening connections. We seal these with moisture-resistant mastic and verify airflow at each register before we leave.

Duct Repair in Old Fig Garden

Duct Repair in Old Fig Garden addresses the physical damage that sealing alone won’t fix: crushed flex duct from a contractor crawling through your attic, rodent-chewed sections in crawlspaces, or original galvanized metal that’s rusted through after eighty years. Many Old Fig Garden homes still have the original unlined duct chases running through uninsulated attics and crawlspaces, and those chases collect decades of Valley dust, almond-hull debris, and rodent nests that standard cleaning can’t fully address. A typical duct repair in Old Fig Garden runs $400 to $950 per section, with whole-system replacement ranging $2,500 to $5,500 for larger estate homes.

Section Replacement

When a duct chase is too compromised to seal, we remove the damaged section and install new, insulated flex or rigid metal with proper supports and sealed joints. We use professional-grade materials from Nikro and Abatement Technologies, the same equipment commercial crews rely on, sized correctly for your system’s CFM requirements.

Return Air Plenum Restoration

The neighborhood’s namesake fig and deciduous canopy drops a thick annual layer of leaves and pollen that overwhelms standard 1-inch filters within weeks. Technicians routinely find Old Fig Garden return-air plenums packed with leaf litter and pollen mats that never show up in newer Fresno subdivisions. We clean and reseal these plenums so your system breathes properly and your filter lasts its full rated life.

Trusted Brands We Service in Old Fig Garden

We seal and repair ductwork connected to every major HVAC brand installed in Old Fig Garden homes, from original gravity-furnace conversions to modern variable-speed systems. Our vans carry mastic, sealants, and mechanical fasteners from Rotobrush and Guardsman, plus filtration products from Honeywell and Aprilaire for homeowners who want to upgrade while we’re already in the attic. Because we dispatch from our Fresno, Central Valley office, parts turnaround for Old Fig Garden customers is typically same-day or next-day, not the week-long waits common with outfits ordering from out of state. If your system needs a component we don’t stock, we tell you before we start and give you the exact timeline in writing.

Common Duct Sealing Problems We See in Old Fig Garden Homes

• Original gravity-furnace chases converted to forced-air. These unlined masonry or wood chases leak at every joint and were never meant to handle pressurized airflow. We find them in the Spanish Revival estates near Palm Avenue and the original Fig Garden Country Club parcels, and they typically need full replacement rather than sealing.
• Seventies-era flex duct turning to powder in the attic. The insulation wrap on flex duct installed during the first oil crisis has a 40- to 50-year lifespan, which means it’s failing now across Old Fig Garden. The outer jacket cracks, the fiberglass disintegrates, and the inner liner tears at every bend.
• Return ducts pulling attic air through gaps around ceiling penetrations. Deep plaster ceilings in Old Fig Garden homes make tight seals difficult, and decades of vibration loosen the connections. Your system ends up recirculating 140-degree attic air mixed with whatever rodent droppings and Valley dust are up there.
• Corroded metal duct at crawlspace low points. Tule fog moisture collects in crawlspaces through winter, and spring irrigation from the neighborhood’s mature landscaping adds groundwater. Galvanized metal duct rusts from the outside in, and homeowners don’t notice until airflow drops by half.
