Selma sits at the heart of California’s raisin grape belt, and the mechanical harvesting and tray-drying operations that blanket the surrounding vineyards every August through September generate dense clouds of fine agricultural dust that infiltrate home HVAC systems at a rate far beyond what urban Valley neighbors experience. Combined with the San Joaquin Valley Air Basin’s chronic PM2.5 problem - one of the worst in the nation - duct systems in Selma accumulate a gritty, pesticide-adjacent particulate load that makes sealing both more urgent and more frequent than in non-agricultural communities. When your ducts leak, that contamination bypasses your filter entirely.

Our Duct Repair & Sealing team has worked the residential streets from downtown Selma west to the vineyard corridors east of town. We know the 1960s-1990s housing stock that dominates this city, the retrofit attic installations common in older west-side homes, and the particular failure modes that Selma’s 100-110°F summers create. We’ll be there when we say.

Why Bellows Air Duct & Vent Co. Is Selma’s Preferred Duct Repair & Sealing Company

We’ve been serving the San Joaquin Valley since 1984, and Selma has been part of our route for decades. Homeowners here don’t want a technician who needs directions to 93662; they want someone who already knows why the flex duct behind the master bedroom in a 1975 ranch sags worse than the identical house in Clovis.

The 90-Day Done Right Promise is stamped on every job - if it’s not right, we make it right, no paperwork, no arguing. Calls are answered by a live person 24 hours a day, not an app or a voicemail tree. Our technicians are background-checked, uniformed, and equipped with camera inspection systems so you see the before and after, not just take our word for it.

Our Duct Repair & Sealing Services in Selma

Flex Duct Repair

Selma’s residential core is dominated by modest single-family homes built largely between the 1960s and 1990s, many of which still have original or early-replacement flex duct runs that have stiffened, sagged, or pulled loose at connections over decades of extreme heat cycling. We replace collapsed or torn flex duct with new insulated runs, secure connections with mechanical fasteners plus mastic, and verify airflow balance before we leave. On a July job near the vineyard corridors east of town, we sealed a collapsed flex duct in a 1978 home off Rose Ave using Rotobrush agitation and mastic sealant, eliminating the reddish-tan dust infiltration that had been clogging the homeowner’s Honeywell filter within weeks.

Mastic Sealant Application

Heavy-duty mastic is the backbone of durable duct sealing in Selma, but mastic alone won’t hold without mechanical fasteners - a shortcut we see too often in older installations. We apply Abatement Technologies mastic over every joint, seam, and penetration, then mechanically secure flex duct collars to plenums so the seal survives another 40 summers. In 93662 attics that reach 130°F, the right mastic applied the right way outlasts tape by years.

Air Leak Repair

Retrofit attic ducts in older west-side Selma homes often lack proper sealing at chase penetrations and register boots, creating pathways for unfiltered outdoor air to enter. We pressure-test systems, locate leaks with smoke pencils and thermal imaging, and seal them at the source. This matters especially in Selma, where the valley’s thermal inversion layers trap smoke, dust, and ozone at ground level year-round.

Metal Duct Repair

Where Selma homes have galvanized trunk lines or transition boxes, we patch corrosion holes, reseal longitudinal seams, and reinforce sagging supports. Metal duct holds up better than flex in high-temperature attics but fails at joints and penetrations - exactly where we focus our repair work.

Duct Insulation

Retrofit attic ducts in older west-side homes near downtown Selma often lack proper insulation, causing condensation and microbial growth that undermine sealing repairs. We add or replace insulation on exposed runs, maintaining the thermal barrier that keeps your conditioned air conditioned and your sealed ducts sealed.

Duct Sealing (System-Wide)

For homes with widespread leakage, we perform comprehensive sealing of the entire distribution system - plenum, trunk lines, branch ducts, and register boots. Every connection gets inspected, every gap gets closed. We camera-verify before and after, so you see the difference.

Trusted Brands We Service in Selma

We carry parts and materials from Rotobrush, Abatement Technologies, Honeywell, and Aprilaire - the same brands serious HVAC contractors specify for the San Joaquin Valley’s demanding conditions. Our trucks are stocked for Selma’s common configurations, which means most repairs don’t wait on a parts run to Fresno. Whether your system uses Honeywell media filters that clog every few weeks during harvest season or Aprilaire humidifier components integrated into your ductwork, we have the components to fix it same day.

Common Duct Repair & Sealing Problems We See in Selma Homes

• Flex duct pulls loose from plenums due to thermal cycling and poor original installation. Selma’s 100-110°F summers expand and contract duct connections hundreds of times per season. We secure these with mechanical fasteners plus mastic, not just tape that dries and fails.
• Mastic sealant alone won’t hold without mechanical fasteners. We see previous “repairs” where someone smeared mastic over a loose collar and called it done. It wasn’t. We do both.
• Agricultural dust load clogs evaporator coils within 1-2 years, masking duct leaks that allow unfiltered outdoor PM2.5 to bypass the system entirely. Technicians working Selma homes near the vineyard corridors east and south of town routinely pull filter and duct debris that carries a reddish-tan agricultural dust rather than typical household dust gray. If your ducts leak, that dust enters your living space whether your filter is new or not.
• Retrofit attic ducts in older west-side homes lack proper insulation, causing condensation and microbial growth that undermine sealing repairs. We seal first, then insulate, so the repair lasts.
