We’ve been working in Irvine’s planned communities since 2004, and there’s a pattern we see repeatedly: a homeowner has their in-unit ducts cleaned or sealed, but the dusty air, pressure imbalance, or high energy bill persists. The culprit is almost always the shared chase or stacked run in the common attic that wasn’t included in the scope. That’s why our Duct Sealing team starts every Irvine condo job with a camera inspection and a clear map of what you own versus what the HOA owns.

Why Hollis Air Duct Cleaning Is Irvine’s Preferred Duct Sealing Company

Hollis Air Duct Cleaning operates under The Garrison Standard, and that matters in Irvine because this city’s dense, planned villages demand a level of documentation and coordination that fly-by-night crews simply don’t provide. When you’re working in a Woodbridge townhome with a shared attic chase, you need a technician who’ll photograph the run, write down the price before touching anything, and leave paperwork the property manager can file.

Our technicians are background-checked and uniformed, and they arrive inside the quoted window. The 365-Day Done Right Promise covers every sealing job in writing: if a joint we sealed fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.

Phones are answered by a live person 24 hours a day, 7 days a week. That’s not a marketing line; it’s operational discipline. When you’re coordinating with an Irvine HOA management company on access to a common attic, you can’t afford voicemail loops or callback queues.

We know the local codes for concealed spaces in Irvine’s condo and townhome tracts, and we carry the professional-grade equipment to do the job by the book: Nikro negative-air machines for contained work, and filtration products from Honeywell and Aprilaire to protect air quality during sealing.

Air Duct Sealing in Irvine

Air Duct Sealing in Irvine means closing the gaps, joints, and degraded connections in your forced-air duct system so conditioned air reaches the rooms it’s supposed to reach instead of leaking into your attic, your walls, or your neighbor’s unit. In this city’s master-planned villages, that work is complicated by shared and stacked duct runs that pass through HOA-controlled common space, so the job often requires coordination with property management before a technician can even assess the full system.

Most Irvine homeowners need duct sealing when they notice uneven temperatures between rooms, dust that returns quickly after cleaning, or energy bills that climb without explanation. In condo and townhome tracts, the telltale sign is often pressure imbalance: a door that won’t stay closed, a return grille that whistles, or a bathroom exhaust that backdrafts. These symptoms point to leaks in the duct system that simple cleaning won’t fix.

Camera Inspection and Access Mapping

We start with a video scope of the accessible ductwork to locate leaks, measure their size, and determine whether the run passes through common structure. In Irvine’s older villages like Woodbridge and El Camino Real, we regularly find original 1970s flexible duct with degraded internal insulation that’s shedding fiberglass into the supply air. The camera footage becomes part of your written estimate and, when needed, documentation for your HOA.

Mastic Application and Pressure Testing

We seal accessible joints with duct mastic and reinforcing mesh, not tape, because mastic remains flexible and bonds to metal and flex duct in Irvine’s temperature swings. After sealing, we run a pressure test to verify the system holds. If the leak is in a shared chase we can’t access without HOA approval, we flag it in writing so you know exactly what remains unsealed and who owns that section.

Duct Sealing Services in Irvine

Duct Sealing Services in Irvine cover the full range of residential forced-air systems found in this city’s planned communities, from single-family homes in Quail Hill and Woodbury with dedicated attic duct runs to condo and townhome units in Westpark and Northwood with shared or stacked duct geometry. The scope of work varies significantly based on whether your ductwork is wholly within your unit or passes through HOA-controlled common space.

Pricing reflects this complexity. A straightforward single-family home with accessible attic ductwork typically runs $850 – $1,600. Condo and townhome jobs involving shared chases, HOA coordination, and camera documentation of common-structure runs usually fall between $1,400 and $2,400. Every price is written down before work begins and does not change at the door.

HOA Coordination and Documentation

In Irvine’s dense villages, we regularly interface with property management companies to schedule access, document existing conditions, and clarify responsibility splits. We provide written reports with camera stills that show which duct sections are in-unit and which are common structure. This protects you from paying to seal something the HOA should maintain, and it gives the HOA the documentation they need to schedule their own repairs.

Dryer Vent Integration

Many Irvine townhomes have dryer vents that run through common walls or attics before exiting the building. Sealing the in-unit portion while ignoring the concealed run leaves lint accumulation and fire risk unaddressed. When we find this configuration, we document the full pathway and coordinate with management on access for cleaning and sealing the common-structure portion.

Trusted Brands We Service in Irvine

We seal and service duct systems connected to all major HVAC brands, and we stock compatible sealing materials and filtration components for Irvine customers to eliminate wait times. Our equipment roster includes Nikro negative-air machines for contained work during sealing, plus Honeywell and Aprilaire filtration products to protect indoor air quality while joints are open. We don’t guess at what fits your system. We measure, match, and keep the right mastic, mesh, and collar sizes on the van so the job finishes in one visit when possible. For Irvine’s older villages with original ductwork, we also carry Abatement Technologies HEPA filtration for jobs where degraded insulation has compromised air quality during the sealing process.

Common Duct Sealing Problems We See in Irvine Homes

• Shared chase leaks in condo attics. Sealing only the in-unit supply and return while the stacked run in the common attic stays open means air keeps migrating between units. We see this in Woodbridge and Westpark townhomes where one unit’s return pulls dust from a neighbor’s leaky supply. The homeowner pays for sealing, but the pressure imbalance and dust return because the full pathway was never mapped.
• Mastic failure on baked flexible duct. Irvine’s inland summers regularly hit the 90s°F, and attic temperatures climb far higher. Flexible duct installed in the 1980s or 1990s has often degraded past the point where sealant will bond. We apply mastic and it cracks off within a season. The real fix is duct replacement, not sealing, and we tell you that upfront.
• Concealed dryer vent lint loads. In older Irvine villages, the dryer vent runs through common structure before exiting. The in-unit portion looks fine, but the concealed section loads lint and creates both fire risk and backpressure that strains the dryer’s heating element. Sealing the unit side without addressing the common run is incomplete work.
• Fiberglass shedding from degraded internal insulation. Original ductwork in 1970s – 80s Irvine homes has internal insulation that, after decades of thermal cycling, breaks down and releases particles into supply air. Sealing the joints doesn’t stop the shedding. We spot this with the camera and recommend replacement of the affected runs, documented for your records and any HOA filing.
