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 Orange
We dispatch our Duct Sealing crews to Orange from our Hartford office, and we know the drive well: straight down I-95, then west toward the older neighborhoods where the real work lives. Orange isn’t a city of identical subdivisions. You’ve got 1920s bungalows crowding Old Towne Orange, mid-century ranches stretching east toward the foothills, and two-story homes from the 1970s and 80s packed into southeast Orange. Each era built its ducts differently, and each era fails differently. That’s why we don’t roll up with a one-size-fits-all pitch. We look at what you’ve actually got, write the price down before we touch anything, and seal it by the book. If you’re in Orange and your ducts are leaking air into your attic or crawl space, call us at (361) 326-5060. We’ll give you a real number, not a teaser that doubles once we’re inside.
Why Hollis Air Duct Cleaning Is Orange’s Preferred Duct Sealing Company
We’ve been at this since 2004, and the Garrison Partners family doesn’t stay in business two decades by baiting and switching. Our 365-Day Done Right Promise means if the seal fails, we come back. No charge. No negotiation. It’s written on every job.
Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the window, price in writing, leave the site clean. Orange homeowners tell us the difference is immediate. You know who’s walking in before they get there. The price they wrote down is the price you pay. And when winter rains soak your attic ducts or Santa Ana winds force your AC to run overtime, that discipline matters more than a coupon ever could.
Phones get answered by a live person, 24 hours a day. No voicemail loops. No “we’ll call you back Monday.” If you’re staring at a duct leak on a Saturday evening, someone picks up.
We serve Orange specifically, not as an afterthought. Our crews understand the local housing stock, the historic preservation constraints in Old Towne, and the climate stresses that split seams and disconnect runs across this city’s varied neighborhoods.
Air Duct Sealing in Orange
Air Duct Sealing in Orange means stopping conditioned air from escaping through gaps, disconnected joints, and deteriorated seams in your ductwork. In a city where much of the housing dates from the 1920s through the 1970s, we see a lot of original uninsulated sheet metal, brittle asbestos-wrapped runs in pre-1930 homes, and crushed flex duct buried under additions or original flooring. When your furnace or AC pushes air through these compromised pathways, you’re heating your crawl space or cooling your attic instead of your living room. Typical Air Duct Sealing in Orange runs $450 – $1,200 for a whole-system seal, depending on accessibility, the extent of disconnection, and whether we need camera inspection to locate hidden breaks.
Non-Invasive Methods for Historic Properties
In Old Towne Orange’s historic district, duct sealing that involves opening walls or altering HVAC equipment can trigger historic preservation review. Our techs use camera inspection and sealant injection from existing access points. We document existing conditions before starting, and we never cut into plaster or lath without a clear plan and homeowner approval. This approach takes longer than wall-cutting, but it preserves the architectural fabric these homes are known for.
Sealing Disconnected Runs
Original gravity furnaces and unlined sheet-metal ducts in 1920s and 30s homes often hide disconnected runs behind plaster walls. Seasonal expansion and contraction worsen these leaks over decades. We locate the break with a camera, rejoin the run where accessible, and seal the joint with mastic rated for your system’s temperature range. The fix is permanent, not a tape job that peels in six months.
Duct Sealing Services in Orange
Duct Sealing Services in Orange cover everything from spot-sealing a single disconnected return to full-system mastic application and aerosol sealant injection for homes with limited access. We don’t price per vent or per linear foot. We price per system, agreed in writing before work starts. That means one flat figure for your whole house, whether you’ve got twelve registers or twenty. Typical Duct Sealing Services in Orange range from $450 for targeted sealing of accessible ductwork to $1,200 for comprehensive sealing with camera inspection and documentation for historic properties. Most jobs fall between $650 and $900.
Camera Inspection and Documentation
We run a borescope through your duct runs before and after sealing. You see what we see: the disconnected joint, the crushed flex, the gap where mastic has crumbled away. After sealing, we show you the closed gap. For Old Towne Orange homeowners, we also document existing conditions for historic preservation records. It’s extra paperwork, but it’s part of working responsibly in a designated historic district.
Aerosol Sealant for Inaccessible Ductwork
When ducts are buried under original hardwood or threaded through inaccessible wall cavities, we pressurize the system and inject an aerosol sealant that finds and plugs leaks from the inside. The sealant particles coalesce at gap edges, building a flexible seal without cutting access holes. It’s not cheap, but for historic homes where wall integrity matters, it’s often the only practical path.

Trusted Brands We Service in Orange
Our vans carry professional-grade equipment, not hardware-store gear. For duct sealing, we stock mastic and sealants from Guardsman, rated for the temperature swings your attic ducts see through an Orange summer. Our rotary brush systems come from Rotobrush, and our negative-air machines from Nikro. We also source filtration products from Honeywell and Aprilaire when a sealing job reveals your return system needs better protection against Santa Ana dust. Because we keep common materials stocked for the Orange market, most sealing jobs finish same-visit. No waiting two weeks for a special-order sealant while your conditioned air leaks into the crawl space.
Common Duct Sealing Problems We See in Orange Homes
- Brittle asbestos-wrapped ducts in pre-1930 Old Towne homes. These ducts crack when agitated during cleaning or inspection. We shift to careful sealing rather than aggressive brushing, preserving the wrap and the airway beneath it. Disturbing friable asbestos without containment is not something we do.
- Disconnected runs hidden behind plaster walls in 1920s and 30s bungalows. Original gravity furnace installations often used slip joints that worked loose as the house settled. We locate the gap with a camera, seal from the nearest access point, and advise when wall opening is truly necessary versus when injection sealing suffices.
- Crushed flex duct under original hardwood in mid-century ranches. East Orange’s 1950s and 60s tract homes often have flex runs flattened by decades of foot traffic or storage weight above. The duct isn’t leaking at a seam; it’s choked entirely. We replace the crushed section and seal the new connection with mastic, restoring airflow without tearing up the floor.
- Moisture intrusion into attic duct runs after winter rains. Orange’s mild, wet winters introduce humidity through roof vent gaps or poorly sealed attic hatches. Come June, the first AC startup pushes musty air through damp duct insulation. The smell often masks underlying seal failure. We inspect attic runs as standard practice, sealing both the duct joint and the attic penetration that let the water in.

FAQs About Duct Sealing in Orange
Yes. We use camera inspection and sealant injection from existing access points, and we document existing conditions before starting. For most leaks in Old Towne Orange homes, we can achieve a complete seal without altering walls or triggering historic preservation review. Call (361) 326-5060 and we’ll assess your specific duct layout.
Santa Ana winds pull fine dust through every gap in your home’s envelope, including duct leaks, and force your AC to run longer from June through September. That extra runtime accelerates seal degradation and pumps unfiltered dust into your living space. Sealing the duct system reduces both the dust load and the cooling hours. We can check your seal integrity before peak season.
Uneven temperatures between rooms, weak airflow at registers farthest from the furnace, and dust accumulation near baseboards where pressurized air escapes into wall cavities. In east Orange ranches, we often find flex runs crushed under original flooring or slip joints that separated as the slab settled. A camera inspection confirms the location without destructive exploration.
Yes. Our sealing methods, material selection, and post-job verification follow NADCA guidelines for residential duct sealing. That means proper surface preparation, mastic rated for your system’s operating temperature, and verification that the seal holds under normal static pressure. We don’t guess; we test.
Moisture has entered your attic duct runs through gaps in roof vents or attic hatches, soaked into duct insulation or settled dust, and sat dormant through the mild winter. The first June startup reactivates the microbial growth. The smell indicates both moisture intrusion and likely seal failure at the attic penetration. We seal the duct joint and the envelope gap that let the water in. Call (361) 326-5060 for an inspection before the next heat wave.
