Laguna Hills was one of the first master-planned communities in South Orange County, and that means most of the housing stock is 40 to 50 years old. The original flexible ductwork in those attics has been baking at 140 – 150°F every summer since the Carter administration. Our Air Duct Cleaning team knows what to look for: brittle R-4 flex, disconnected returns, crushed runs behind knee walls, and plenums so leaky they cool the attic instead of the bedroom. Dispatch and scheduling are coordinated from our Los Angeles office, but the crews that roll into Laguna Hills are local and carry extra flex duct on every truck.

Why Hollis Air Duct Cleaning Is Laguna Hills’s Preferred Air Duct Cleaning Company

We’ve been in business since 2004 as part of the Garrison Partners family, and that track record matters in a market where bait-and-switch pricing is common. Every Hollis job in Laguna Hills starts with a written price that does not move once the technician is inside your home. No per-vent add-ons, no surprise charges for “extra contamination.” The price is the price.

Our technicians are background-checked, uniformed, and expected to operate under The Garrison Code: arrive inside the quoted window, explain what they found before they fix it, price it in writing, complete the job by the book, and leave the site clean. The 365-Day Done Right Promise covers every repair in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit.

Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday for someone to call you back.

Residential Air Duct Cleaning in Laguna Hills

Residential Air Duct Cleaning in Laguna Hills usually involves more than running a brush through the ducts. In a typical 1970s or 1980s tract home in neighborhoods like Moulton Ranch, we start with a video inspection because the real problems are often hidden in the attic: original R-4 or R-6 flex duct that has gone brittle from years of heat exposure, disconnected returns dumping conditioned air into the insulation, or crushed runs pinched behind knee walls where a previous contractor stuffed storage boxes. A standard residential cleaning runs $380 – $680, but if we find failed flex or a leaky plenum, replacement and sealing runs $850 – $1,800 depending on how many runs need work. We always show you the camera footage and explain the options before anything gets cut.

Supply Duct Cleaning and Replacement

Supply ducts carry cooled air from your air handler to each room. In Laguna Hills, we often find supply runs with cracked jackets or collapsed insulation, especially on south-facing roof sections where attic temperatures peak. We source-remove debris with a rotary brush system, then replace failed flex and seal collars with mastic so the air you paid to cool actually reaches the register.

Return Duct Cleaning and Sealing

Return ducts pull warm air back to the air handler for reconditioning. A disconnected return in a 140°F attic sucks in superheated air and fiberglass particles, which is why your AC runs constantly but the house never cools. We test static pressure before and after, and we seal every joint so the system breathes through the house, not the insulation.

Commercial Air Duct Cleaning in Laguna Hills

Commercial Air Duct Cleaning in Laguna Hills covers the office parks along El Toro Road, the medical suites near Saddleback Memorial, and the retail and multifamily properties around the Laguna Hills Mall and Civic Center area. These buildings typically have larger rooftop units, longer trunk lines, and more complex zoning than residential systems. A commercial cleaning runs $650 – $1,400 for standard office space, with larger multifamily or medical facilities quoted after a walkthrough. We use Nikro negative-air machines on commercial jobs to maintain containment while we work, and we schedule around your hours so you’re not explaining dust to patients or tenants.

Full System Cleaning for Office and Retail

We clean supply and return trunk lines, branch ducts, diffusers, and the air handler cabinet. For properties with multiple zones, we isolate each section and clean sequentially so the building stays operational. We document before-and-after conditions with photos for your maintenance records.

Video Inspection and Documentation

Commercial clients in Laguna Hills often need documentation for property managers or insurance. We record video of duct conditions, note any corrosion or failed insulation, and flag code or safety issues we observe. The report goes to you, not buried in a sales pitch.

Trusted Brands We Service in Laguna Hills

Our trucks carry professional-grade equipment, not hardware-store gear. We run Rotobrush rotary brush systems for source removal in residential ducts, Nikro negative-air machines for commercial containment, and we stock filtration products from Honeywell and Aprilaire for homeowners who want to upgrade after a cleaning. For properties with specialized containment needs, we also work with Abatement Technologies HEPA filtration. We keep common flex duct sizes, collars, and mastic on every Laguna Hills truck so we’re not making a supply run while your attic is open to the heat. That matters in July when every hour of delay is another hour your system is down.

Common Air Duct Cleaning Problems We See in Laguna Hills Homes

• Brittle, heat-degraded flex duct. Original R-4 and R-6 flex in 1970s – 80s Laguna Hills attics has been exposed to 140 – 150°F summer temperatures for decades. The jacket cracks, the insulation compresses, and the run either collapses or slips off the collar entirely. A basic cleaning without replacement leaves the same leak path blowing conditioned air into your insulation.
• Disconnected or crushed runs behind knee walls. In two-story tracts like Moulton Ranch, flex runs often get pinched where they pass through tight framing or where a homeowner or previous contractor used the cavity for storage. Without a camera inspection, these go undetected. The blower motor amps look normal, but half the supply air never reaches a register.
• Leaky plenums and register boots. The sheet-metal plenum connecting your air handler to the duct trunk is sealed with tape that dries out after 20 years in a hot attic. Gaps here create negative pressure that pulls attic dust and insulation fibers into the system. We seal with mastic, not tape, because mastic survives the heat.
• Wildfire smoke and Santa Ana wind particulate. Laguna Hills averages 296 sunny days and minimal rainfall, but Santa Ana wind events and regional wildfire smoke push fine particulate through every gap in the building envelope. Once it’s in the ducts, standard HVAC filters don’t remove it. Source removal with HEPA filtration is the only way to get it out.
