Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Sealing Across Perris
Duct sealing in Perris typically runs $800 – $2,400 for a whole-home system, with most jobs completed in a single day and priced in writing before we start. We’re the Perris crew from Hollis Air Duct Cleaning, and we know what the Santa Ana winds do to your ductwork. Our dispatch is coordinated from the Inland Empire office, but our trucks are local to Perris, and we serve neighborhoods from the older ranch homes near Perris Boulevard to the newer tracts off the 215 corridor. If you’re tired of wiping that reddish-tan film from your return registers every spring, call (361) 326-5060. We’ll show you exactly where your ducts are leaking and seal them right.
Why Hollis Air Duct Cleaning Is Perris’s Preferred Duct Sealing Company
We’ve been working in Perris homes since 2004, and the pattern is consistent: homeowners who’ve had their ducts cleaned three times in two years still see dust because nobody sealed the leaks. Our Duct Sealing team doesn’t just vacuum out what’s loose; we find where the dust is getting back in and stop it.
Roy Castellanos built this operation on The Garrison Standard, which means written prices before any work starts, background-checked and uniformed technicians, and a 365-Day Done Right Promise on every job. If a seal fails within a year, we come back at no charge, including a free second visit. No negotiation, no runaround.
Our phones are answered by a live person 24 hours a day, 7 days a week. When you call (361) 326-5060, you talk to a human who can book your appointment, not a voicemail loop that sends you to a callback queue.
We know Perris specifically. We know the 1970s rigid metal ductwork in the neighborhoods near the Perris Valley Airport. We know the 2000s flexible ducting in the eastern tracts that sags and collects silt. That local knowledge means we diagnose faster and fix it right the first time.
Duct Insulation in Perris
Duct Insulation in Perris is often the missing piece in homes where the AC runs hard from April through October but the upstairs rooms never cool down. In this city, uninsulated or poorly insulated ductwork in 100°F attitudes loses conditioned air before it ever reaches your living space. We wrap existing supply runs with formaldehyde-free fiberglass insulation or closed-cell foam sleeves, sealed at every seam with mastic, so the air that leaves your handler arrives at the register at the temperature it was meant to be.
A typical Duct Insulation job in Perris runs $600 – $1,800 depending on linear footage and attic accessibility. Homes with original 1950s – 1980s rigid metal trunk lines often need this most, since the insulation that was installed decades ago has compressed, torn, or fallen away entirely.
Attic Heat and Your Energy Bill
Perris attics hit 140°F in July. Uninsulated ducts in that environment are trying to push 55°F air through a convection oven. The system runs longer, wears faster, and still doesn’t cool the house. Proper insulation cuts that load and gives your equipment a fighting chance.
What We Use
We install insulation products from Abatement Technologies and Guardsman, rated for the temperature swings and rodent exposure common in Inland Empire attics. Not hardware-store wrap. Material that holds its R-value and stays sealed.
HVAC Duct Sealing in Perris
HVAC Duct Sealing in Perris is the service that finally stops the cycle of clean-then-dusty-then-clean-again that so many homeowners are stuck in. The job involves pressurizing your duct system to locate leaks, then sealing joints, connections, and penetrations with mastic and fiberglass mesh, or with aerosolized sealant for inaccessible runs. We finish with a verification test to confirm the leakage rate has dropped to acceptable levels.
Typical HVAC Duct Sealing in Perris costs $800 – $2,400 for a whole-home system. Smaller homes with straightforward access fall at the lower end; larger homes with multiple zones, hard-to-reach attic runs, or significant disconnection damage run higher. We price it in writing before we start, and that number does not move at the door.
Leak Detection Before Sealing
We don’t guess. We pressurize the system and use a calibrated fan to measure actual leakage in CFM. In Perris, we regularly see older homes losing 25 – 40% of conditioned air to the attic through failed joints. You can’t seal what you haven’t measured.
Mastic vs. Tape
Duct tape fails in Perris heat. We use water-based duct mastic, reinforced with mesh at stress points. It remains flexible at temperature extremes and bonds to metal, fiberglass, and flexible ducting. In 2000s tract homes with flexible ducting, we often find the original tape has turned to powder.
Trusted Brands We Service in Perris
We stock parts and sealing products from Aprilaire, Abatement Technologies, and Guardsman, so Perris homeowners aren’t waiting on a warehouse shipment while their AC struggles through another 100°F week. Our equipment roster includes Rotobrush rotary brush systems for pre-sealing cleaning and Nikro negative-air machines for containment. When we seal your ducts, we do it with the same materials commercial HVAC contractors specify, and we explain what we’re using and why before we open a single can of mastic.
Common Duct Sealing Problems We See in Perris Homes
- Deteriorated duct tape on original rigid metal joints. In the 1950s – 1980s homes that make up much of Perris’s core housing stock, the original cloth-backed tape crumbles after decades in attic heat. We peel off the residue and seal with mastic and mesh that won’t fail next summer.
- Disconnected trunk takeoffs dumping air into the attic. After Santa Ana wind events, vibration and thermal expansion loosen connections. We find these with camera inspection, reconnect the run, and seal the joint so it stays put.
- Crushed flexible ducting in 2000s eastern and southern tracts. The flexible ducting used in newer Perris construction sags at low points, collecting that reddish-tan silt and sometimes kinking completely shut. We replace damaged sections and support the new run properly.
- Undocumented tie-ins from swamp coolers and window units. Older Perris homes often have aftermarket cooling additions that bypass the main duct system. We map these during inspection and seal or reroute so your primary system isn’t fighting uncontrolled leakage paths.
Pricing for Duct Sealing in Perris, CA
Whole-home duct sealing in Perris typically runs $800 – $2,400. Duct insulation alone ranges $600 – $1,800. Combined sealing and insulation jobs for older homes with extensive attic ductwork often fall in the $1,400 – $3,200 range. What moves you within these ranges: linear footage of ductwork, attic accessibility, whether we need to repair or replace crushed or disconnected sections, and whether we’re also cleaning decades of accumulated silt before we seal.
Every Hollis job starts with a written price before any work begins. No estimates that balloon once the technician is inside. We show you the camera footage, explain what we found, and give you the exact cost to fix it. If you choose not to proceed, you pay nothing for the inspection.

FAQs About Duct Sealing in Perris
You’re seeing decomposed granite silt from the Lakeview Mountains and surrounding dry lakebeds that bypasses your filter and enters through leaky duct joints. Duct sealing closes those entry points so the dust stays in the return, gets caught by the filter, or never enters the system at all. Call (361) 326-5060 and we’ll show you the leak locations with a camera.
It almost certainly needs both. The original duct tape on 1970s rigid metal joints has likely failed, and the leaks that opened are pulling attic dust directly into your airflow. We clean first to remove accumulated debris, then seal so it doesn’t return. A written quote for both steps is free.
Yes. Perris sits in the dustiest wind corridor of the region, where Santa Ana events deposit fine silt that bypasses standard filters. Sealing is what stops that dust from re-entering after every wind event; cleaning alone just resets the clock. Call (361) 326-5060 for an inspection and we’ll show you the difference.
Flexible ducting that sags at low points, collecting silt and sometimes kinking shut, plus original tape that has turned to powder in the attic heat. Camera inspection usually reveals the damage, and we replace failed sections before sealing the intact runs. Free estimates available at (361) 326-5060.
Yes, but we need to map those tie-ins first. Undocumented connections from aftermarket cooling additions often bypass the main duct system and create uncontrolled leakage paths. We inspect the whole system, identify all airflow paths, and seal or reroute so your primary system works as designed. Call (361) 326-5060 to schedule.
