We’ve been cleaning ducts in Cypress long enough to know what separates a proper job from a quick vacuum-and-go. The homes here tell a specific story. Most were built in the 1960s and 1970s by S&S Construction and similar developers, with rigid metal trunk lines sized for gravity furnaces, not the central air systems that were retrofitted decades later. That matters because oversized ductwork doesn’t move air efficiently; it lets dust settle in the dead zones. Add to that the unique Cypress problem of return air plenums routed through garages, and you’ve got a contamination path that generic duct cleaners from outside the area simply don’t recognize. Our Air Duct Cleaning team is trained to spot it and fix it.

Why Hollis Air Duct Cleaning Is Cypress’s Preferred Air Duct Cleaning Company

Hollis Air Duct Cleaning has built its reputation in Orange County on The Garrison Standard: written prices, written guarantees, and technicians who arrive inside the quoted window wearing a uniform and a name you can verify. We’re part of the Garrison Partners family, in business since 2004, and every Hollis location operates independently with the same discipline.

In Cypress specifically, homeowners call us back because we don’t treat their 1970s ranch like a cookie-cutter new build. We know the S&S Construction layouts. We know the garage plenum issue. We know that homes near the Los Alamitos border get hit harder by marine layer humidity pushing into attic flex ducts. Roy Castellanos, who leads our operation, insists that every technician working in Cypress understands these local conditions before they step out of the van.

Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. When you’re ready to schedule, you talk to a human who can book your slot and confirm your written estimate.

Every job carries the 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge, including a free second visit. That’s not a slogan; it’s printed on every invoice.

Air Duct Repair in Cypress

Air Duct Repair in Cypress usually means fixing the damage that decades of retrofit work and garage contamination have caused to original 1960s-70s systems. We find crushed flex offshoots behind garage plenums, disconnected returns pulling unfiltered garage air, and metal trunk lines corroded by condensation from the marine layer. Repair costs in Cypress typically range from $200 – $500 for minor resealing and reconnection, and $800 – $1,800 when we need to replace multiple flex runs or rebuild a plenum. We always inspect with a camera first, show you the footage, and give you a written price before any repair begins.

Garage Plenum Rebuilds

The return air plenum running through your garage is the single biggest Cypress-specific failure point we see. Car exhaust and lawnmower fumes coat the duct walls with a tacky film that no household vacuum can remove. Our repair rebuilds or reseals this plenum with proper mastic and mechanical fasteners, then tests for negative pressure integrity so your system stops drawing garage air into your living space.

Oversized Duct Modifications

When a gravity-furnace trunk line was left in place for a modern air handler, the airflow drops and dust settles in the oversized offshoots. We don’t just clean around the problem. We measure static pressure, identify the dead zones, and either install proper dampers or replace the oversized runs with correctly sized flex duct so your system actually moves air to every room.

Ductwork Cleaning in Cypress

Ductwork Cleaning in Cypress requires more than running a brush down a trunk line. The combination of original rigid metal, retrofitted flex R-6 insulation, and garage-sourced contamination means a proper clean here uses negative-air machines with HEPA filtration, rotary agitation tools, and source-removal methods that extract debris rather than pushing it deeper. A standard residential ductwork cleaning in Cypress runs $350 – $650; commercial systems or homes with extensive contamination start around $800 and can reach $1,400 for full system restoration. We price by the system, not by the vent, and we put that price in writing before we start.

Negative-Air Source Removal

We set up a Nikro negative-air machine at your air handler, creating suction through the entire duct network while we run rotary brushes and compressed-air whips through each branch. This pulls loosened debris out of the system rather than letting it escape into your home. For Cypress homes with the garage plenum film, this is the only method that actually removes the contamination instead of smearing it around.

Camera Verification

After cleaning, we run a video inspection through your trunk lines and major branches. You see the before and after on a handheld monitor. In Cypress, this matters especially for the garage return run, where we want you to see that the sticky exhaust film is gone, not just hidden behind a fresh layer of dust.

Trusted Brands We Service in Cypress

We clean and service duct systems connected to Honeywell, Aprilaire, and Abatement Technologies filtration and purification equipment. Our vans carry replacement filters, UV lamp sleeves, and electronic air cleaner cells for these brands, so Cypress homeowners don’t wait days for parts. If your system includes a Honeywell whole-house media filter or an Aprilaire dehumidifier tied to your ductwork, we inspect and service those components during the same visit. We also work with Nikro negative-air equipment and Rotobrush rotary systems on every job, using the same tools commercial crews rely on in hospitals and schools.

Common Air Duct Cleaning Problems We See in Cypress Homes

• The garage return plenum film. In Cypress’s 1960s-70s tracts, the return air plenum runs through the garage, pulling in car exhaust and lawnmower fumes that coat duct walls with a sticky film no other nearby city’s housing stock shares. Cleaning the visible trunk line while leaving this film untouched means every supply register recontaminates within weeks.
• Condensation in attic flex ducts near the Los Alamitos border. The marine layer pushes humidity into attics in this part of Cypress, causing condensation on the interior of flexible R-6 ducts. Homeowners see clean exterior insulation and assume the ducts are fine, while mold grows on the interior walls where they can’t see it.
• Oversized offshoots from gravity-furnace retrofits. Original rigid metal trunk lines sized for 1960s gravity furnaces were left in place when central air was added. The new flex offshoots are too large for the airflow, creating dead zones where dust settles permanently. Running a brush through without checking sizing just stirs that dust back into the air handler.
• Crushed flex runs behind garage plenums. Retrofit flex duct was often routed through tight spaces behind the garage return plenum, where it gets flattened by storage items or its own weight over decades. Airflow to back bedrooms drops, and homeowners blame the air conditioner instead of the duct.
