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 Lake Elsinore
We’re the Duct Sealing crew Hollis Air Duct Cleaning dispatches from our Inland Empire office to Lake Elsinore homes, and we know the difference between a tract built in 1995 and one finished last year off the I-15 corridor. Lake Elsinore’s hot-summer Mediterranean climate pushes attic temperatures past 140°F, and that expansion and contraction cycle loosens duct connections faster here than in coastal markets. If your registers are blowing weak, your upstairs rooms won’t cool, or your energy bill spiked after the last Santa Ana wind event, call (361) 326-5060. We price every job in writing before we touch anything, and we back it with our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Lake Elsinore’s Preferred Duct Sealing Company
We’ve been serving Riverside County since 2004 as part of the Garrison Partners family, and our Lake Elsinore customers know our technicians arrive uniformed, background-checked, and inside the quoted window. The Garrison Standard requires written pricing before work starts, and we don’t bend that rule for anyone.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. When you call (361) 326-5060, you talk to someone who can schedule you.
We understand Lake Elsinore’s housing stock: the 1980s and 1990s builds with aging flexible ductwork in hot attics, the 2000s subdivisions, and the fast-growing Alberhill Ranch and Canyon Hills communities where new construction debris still sits in ducts at move-in. That local knowledge changes what we look for during inspection and how we sequence the work.
Every repair is covered for 365 days. If it fails, we come back at no charge. No negotiation. No runaround.
Duct Insulation in Lake Elsinore
Duct Insulation in Lake Elsinore addresses a problem most homeowners don’t notice until July: attic temperatures that exceed 140°F cook the air inside uninsulated or poorly insulated duct runs before it ever reaches your living room. In Lake Elsinore’s climate, where summer days regularly top 100°F and attic heat soars far higher, thin or degraded duct insulation forces your HVAC system to run longer cycles, driving up electric bills and shortening compressor life. We typically see this in homes built between the 1980s and early 2000s, where original fiberglass wrap has compressed, torn, or been disturbed by rodents. A typical Duct Insulation job in Lake Elsinore runs $800 – $1,800 depending on linear footage, attic accessibility, and whether we’re re-insulating after sealing leaks. We use professional-grade materials from Abatement Technologies and Guardsman, specified to California Title 24 energy standards.
When Insulation Fails in Hot Attics
Compressed or torn insulation doesn’t just lose R-value; it creates thermal bridges where attic heat pours directly into the duct metal. We see this most often above second-story bedrooms in Lake Elsinore’s two-story tracts, where the longest runs sit under the hottest roof planes. Our crew removes the damaged wrap, seals any exposed leaks first, then installs new insulation with vapor barrier facing correct to code.
New Construction Gaps
Builders in Lake Elsinore’s 2010s boom often insulated ducts to minimum code but left gaps at boot connections and collar joints. Those uninsulated spots become condensation points in shoulder seasons and heat sinks in summer. We treat them during our sealing pass, not as an afterthought.
HVAC Duct Sealing in Lake Elsinore
HVAC Duct Sealing in Lake Elsinore closes the gaps, cracks, and disconnected joints that let conditioned air escape into your attic and pull unfiltered outdoor air back into your system. In Lake Elsinore’s market, we find two distinct failure patterns: older homes where decades of heat cycling have loosened every mechanical connection, and newer homes where builder-grade installation left boot leaks and unsealed takeoffs from day one. A typical HVAC Duct Sealing job in Lake Elsinore runs $600 – $1,400 for a single-system home, with whole-house multi-zone systems reaching $1,800 – $2,500. We use mastic sealant and mechanical reinforcement, not tape that degrades, and we verify results with a duct blaster or pressure pan test when conditions allow.
Sealing After Source Removal
We will not seal ducts that contain construction debris or heavy dust loads. Sealing over drywall dust, joint compound, or Santa Ana grit locks that material against the duct wall permanently, creating a future mold risk and restricting airflow. Our protocol is source removal first, then seal. That’s The Garrison Standard.
Flexible Duct Reconnection
Lake Elsinore’s attic heat doesn’t just loosen connections; it degrades the flexible duct itself. We find collapsed or kinked runs in homes where the original strap spacing was too wide. We re-support with proper tension, replace damaged sections with new flex rated for the application, then seal every joint.
Trusted Brands We Service in Lake Elsinore
Our equipment roster includes Rotobrush rotary brush systems for agitation cleaning, Nikro negative-air machines for source removal, and filtration and sealing products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. We stock common boot sizes, collar diameters, and mastic compounds so Lake Elsinore customers aren’t waiting on a parts run to Murrieta. When your system needs a specific register boot or a replacement flexible duct section, we usually have it on the van. That matters in July when your upstairs bedroom is 85°F and you need the job finished today, not next Tuesday.
Common Duct Sealing Problems We See in Lake Elsinore Homes
- Construction debris in new tracts. In Lake Elsinore’s 2010s-vintage I-15 corridor tract homes, the ducts are usually dirtier at year one than at year ten. Drywall dust, joint compound, and framing sawdust from construction sit in the supply and return ducts long after the builder’s final walkthrough, and no code or builder warranty obligation requires them to be removed.
- Boot and collar leaks from thermal cycling. Lake Elsinore’s 100°F+ summers expand attic-mounted flexible ductwork until boot connections and collars pull loose. New leaks open right next to the ones we just sealed if we don’t also re-strap and reinforce the mechanical connection.
- Santa Ana dust coating return ducts. After a Santa Ana wind event, fine reddish-brown dust from the Lake Elsinore dry lakebed and surrounding scrubland coats return ducts near attics. Sealing those runs before source removal locks the abrasive grit against the duct wall.
- Undersized or collapsed flex runs. Fast construction in the Canyon Hills and Alberhill Ranch areas sometimes meant minimum-spec flexible duct strapped too loosely. Over years, the sag creates a low point where dust collects and airflow chokes.

FAQs About Duct Sealing in Lake Elsinore
Yes, and possibly more urgently than a 1990s home. A family in the Alberhill Ranch tract off Lake Street called us three months after move-in because every register was puffing white dust. Our tech ran a camera inspection down the main trunk and found drywall dust and joint compound caked past the first takeoff. Builder handover in Lake Elsinore’s newer tracts leaves construction debris in the ducts, and sealing over that debris traps it permanently. We clean first, then seal. Call (361) 326-5060 for an inspection.
That’s fine dust from the Lake Elsinore dry lakebed and surrounding scrubland, pulled through gaps in your return duct by the negative pressure of your air handler. The Santa Ana winds funnel through the Elsinore Trough and load the air with abrasive grit that settles on duct walls. Sealing those leaks stops the infiltration, but only after we remove the existing dust load. Call (361) 326-5060 and we’ll show you on camera.
We won’t, and any contractor who does is cutting a corner that will cost you later. Sealing over drywall dust, joint compound, or Santa Ana grit locks that material against the duct wall permanently. It restricts airflow, creates a future mold risk, and voids the value of the seal. Our protocol is source removal under negative pressure first, then mastic sealing. That’s The Garrison Standard, and it’s how we honor our 365-Day Done Right Promise.
Yes, measurably. When your ducts leak 20 – 30% of conditioned air into a 140°F attic, your system runs longer cycles to cool the same space. Sealing those leaks drops run time, reduces compressor wear, and can lower summer electric bills by 15 – 25% in Lake Elsinore’s climate. The payback period is typically 2 – 4 years, faster if your ducts are severely leaking. Call (361) 326-5060 for a pressure test that quantifies your losses.
Dirty ducts blow visible dust and debris; leaking ducts show different symptoms: uneven temperatures room to room, weak airflow at distant registers, excessive dust accumulation around return grilles, and utility bills that spike in summer without explanation. In Lake Elsinore, we often find both problems together, especially in newer tracts where construction debris sits inside ducts with unsealed joints pulling in attic air. We inspect with a camera and pressure test to tell you exactly what you’re dealing with. Call (361) 326-5060 for a free estimate.
