We know Rendon’s homes and we know what decades of Texas heat does to ductwork. The houses out here aren’t like the tight new builds in Mansfield or Southlake. They’re older, they sit on bigger lots, and their duct systems have been breathing oak pollen and fine Pecan dust for thirty or forty years. That’s a different set of problems, and it takes a crew that has seen them before.

Why Hollis Air Duct Fort Worth Is Rendon’s Preferred Duct Sealing Company

Rendon homeowners call us because we put the price in writing before any work starts and we don’t move it. Not at the door, not after the camera inspection, not ever. That matters more than it should in this trade, but we’ve built our reputation in Rendon on exactly that discipline. Roy Castellanos runs our crews to The Garrison Code: arrive inside the window, price it before you touch it, do it by the book, leave the site clean.

Our technicians are background-checked and uniformed. When we schedule a duct sealing job in Rendon, you’ll know the name of the person walking into your home before they arrive. That’s not a courtesy. It’s how we run every job. And if the work doesn’t hold, the 365-Day Done Right Promise means we come back at no charge for a full year. Written, not spoken.

We answer the phone with a live person 24/7. When a Rendon homeowner calls at 7 a.m. because their air handler is screaming, nobody goes to voicemail. Dispatch and scheduling for this area run out of the Dallas-Fort Worth office, and we keep crews routed through Rendon every week. Response time here is short because we’re already in the area, not driving across the metro to reach you.

HVAC Duct Sealing in Rendon

HVAC Duct Sealing in Rendon means going into attics where original flex ducts from the 1970s and 80s have sagged, disconnected at the boot, or been crushed under insulation and stored boxes. The work involves finding every point where conditioned air escapes before it reaches a register, then sealing those gaps with mastic, foil tape rated for high humidity, or replacing runs that are beyond repair. In Rendon’s older homes, it’s rarely a one-gap job. It’s usually several.

You need duct sealing when your system runs but rooms stay uneven, when dust coats surfaces days after cleaning, or when your energy bill climbs without a change in usage. Those are signs of leakage. In Rendon’s larger-lot homes, the system simply runs more because the attic bakes in summer heat, and every degree of inefficiency multiplies.

Sealing Supply and Return Connections

Most leakage in Rendon happens where flex duct meets the boot or the plenum. Over decades of heat and humidity cycles, the original tape dries, cracks, and lets go. We seal these connections with mastic, which flexes with the duct instead of peeling away.

Whole-System Static Pressure Checks

Before we quote any sealing work, we measure static pressure at the air handler. Low pressure on the return side often means a crushed or disconnected run somewhere in the attic. We find it with a camera inspection, not guesswork.

Duct Repair in Rendon

Duct Repair in Rendon usually means replacing what sealing alone can’t save. When a return duct has collapsed under insulation weight or a supply run has been chewed through by rodents nesting in a mature tree line, the fix isn’t tape. It’s removal and replacement. We carry replacement flex duct and connectors on our trucks, so most repairs on Rendon homes are finished the same day without a second trip.

Homeowners here often don’t know they have a crushed return until we show them the camera footage. A house off Rendon Road taught us that pattern well: the homeowner called for a cleaning, but our tech found a 40% airflow drop at the air handler and traced it to a return flex duct from the 1980s that had collapsed under insulation weight. We replaced that run, sealed the supply and return connections with mastic, and restored negative pressure. The allergy symptoms eased within a week. That’s what duct repair in Rendon actually looks like.

Replacing Crushed Return Runs

Return ducts under attic insulation or stored boxes flatten over time. The blower starves for air, registers lose flow, and the motor runs hotter than it should. We cut out the collapsed section, size the replacement for the system’s CFM, and reconnect with sealed collars.

Rodent Damage Restoration

Larger lots with mature oaks and pecans mean more wildlife in Rendon attics than in tighter subdivisions. Squirrels and rats chew through flex duct, letting attic air bypass the filter entirely. We repair the damage and seal entry points to keep it from repeating.

Trusted Brands We Service in Rendon

Most duct systems in Rendon are original to the house, and the manufacturers vary. We work on all of them, and we service air handlers and filtration setups from Honeywell, Aprilaire, and Guardsman. For negative-air cleaning and sealing prep, we run Rotobrush and Nikro equipment, the same tools commercial crews use. We stock common flex duct sizes, mastic, and connectors on our trucks, so when we open up a 1979 attic in Rendon, we’re not driving back to a warehouse for parts.

Common Duct Sealing Problems We See in Rendon Homes

• Disconnected boots on original 70s flex duct. The tape used forty years ago wasn’t made for Rendon’s humidity. It dries, cracks, and the duct falls off the boot. Conditioned air pours into the attic instead of the bedroom.
• Crushed return ducts under insulation. Homeowners add insulation over the years and the weight flattens the return runs below. Static pressure drops, airflow drops, and rooms at the far end of the house never get comfortable.
• Rodent-chewed flex runs near tree lines. Rendon’s larger lots back up to mature oak and pecan trees. Attic rodents chew through foil-faced flex and the system starts pulling unfiltered attic air.
• Failed tape at the plenum connection. The seam where the main supply trunk meets the air handler is a weak point. In a humid summer, that tape lets go and the attic becomes an extension of your duct system.
