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.

AfterCarrier Air Duct Cleaning in Oakland, CA | Hollis Air Duct Cleaning
Air Duct Cleaning in Oakland runs $290 – $490 for a whole-home system, and we’re the crew that does it right the first time. We’re independent Carrier specialists, not a manufacturer affiliate, which means we call it like we see it on every Performance, Infinity, and WeatherMaker system we open up. Oakland’s ductwork fights two enemies at once: wildfire ash from the Diablo winds and mold from the coastal fog. Call (361) 326-5060 for a written estimate before any work starts.
Why Oakland Residents Choose Us for Carrier Service
Roy Castellanos built Hollis Air Duct Cleaning around one rule: leave every system cleaner than he found it, with no guessing and no upsells. He learned HVAC fundamentals through the sheet metal and air conditioning program at Los Angeles Trade-Technical College, then spent years doing hands-on duct work before starting this company in 2004. That’s the difference. We don’t send a salesperson with a clipboard. We send a technician who knows Carrier’s ducted platforms well enough to explain exactly what he found inside yours.
Oakland homeowners call us because we understand how Carrier equipment behaves in this city’s specific housing stock. Pre-1950 Craftsman bungalows and Victorians have original galvanized or asbestos-wrapped ducts that corrode, separate at the seams, and pull in whatever’s floating in the air outside. Our Carrier sales & service work covers the full range of what we find. We also arrive inside the quoted window, price everything in writing before we touch the system, and back the work with our 365-Day Done Right Promise. That’s not marketing language. It’s on the invoice.
Common Carrier Air Duct Cleaning Problems We Solve in Oakland
- Corroded duct trunks on WeatherMaker and older Performance furnaces: Oakland’s damp marine layer keeps moisture inside original galvanized ducts, especially in Rockridge and Temescal bungalows built before 1950. The sheet metal rusts at the seams, separates, and starts pulling mold spores directly into the return side. Cleaning alone won’t fix a separated joint. We seal it with mastic after cleaning so the system stops inhaling outside air.
- Ash-clogged supply ducts on Infinity systems in the hills: During fall Diablo wind events, wildfire smoke and fine charred debris push through the eaves and into the return, then lodge throughout the supply side. Carrier Infinity variable-speed blowers read that restriction as an airflow error and can trigger pressure switch faults. We remove the ash and debris, then rebalance the blower so the system stops throwing codes.
- Raccoon and squirrel damage to flex duct in the flatlands: Oakland’s flatland neighborhoods have a real attic wildlife problem. Raccoons and squirrels tear apart flexible duct runs connected to Carrier air handlers, leaving droppings and shredded insulation throughout the supply side. We replace the damaged runs and clean out what the animals left behind.
- Biological growth on evaporator coils in fog-heavy neighborhoods: The Golden Gate fog keeps indoor humidity high in areas like Rockridge and Temescal. Carrier evaporator coils grow biological film that restricts airflow, forcing the system to run longer and pull more spores and smoke into the return. We clean the coil by the book, not with a quick spray that leaves the underside fouled.
- Duct chases sharing space with knob-and-tube wiring and asbestos wrap: Many pre-war Oakland homes have original duct chases that run alongside old electrical work and asbestos-wrapped pipes. That means cleaning requires careful containment so we don’t disturb material that should stay put. We assess this before we start and build it into the written price.
Carrier Service in Oakland: What Local Conditions Mean for Your Equipment
Here’s what makes Oakland genuinely different from a neighboring city like Berkeley or Alameda. Oakland’s pre-1950 Craftsman bungalows and Victorians often have original duct chases that share wall cavities with knob-and-tube wiring and asbestos-wrapped pipes. That combination is rare in newer construction, and it changes how Carrier duct cleaning has to work here. You can’t just drop a vacuum line into the register and start pulling. We have to contain the workspace, verify we won’t disturb the old wiring or wrap, and often do sealing work that goes beyond standard vacuuming. In the Oakland Hills, we cleaned a Carrier Infinity system in a 1940s ranch home where the supply ducts were packed with fine ash and charred debris from past wildfires, and the return had mold growth from coastal fog. Our tech sealed corroded joints with mastic, replaced a torn flex run damaged by raccoons, and cleaned the evaporator coil. The smoke smell that had lingered for months was gone. That’s the job.
Carrier Models & Products We Service in Oakland
We work on Carrier Performance series air handlers and furnaces, Infinity series gas furnaces and heat pumps, WeatherMaker legacy furnaces, and Comfort 80% and 90%+ gas furnaces. For critical blower and coil repairs, we use OEM-grade Carrier-compatible components. For duct sealing and flex duct replacement, we choose high-quality aftermarket materials that meet or exceed original specs, because the original flex duct from the 1990s isn’t worth matching. We keep common Carrier components stocked locally so we’re not waiting on freight for most Oakland jobs. If your furnace or air handler is over 15 years old with corroded heat exchanger or coil issues, we’ll give you an honest repair-or-replace assessment instead of selling a rebuild that won’t hold up. This is our Oakland service area, and we know what these systems look like after two decades of fog and smoke.

FAQs – Carrier Air Duct Cleaning in Oakland
Wildfire smoke carries fine ash and charred carbon that’s finer and more adhesive than household dust. It clings to duct walls, clogs blower wheels, and embeds a smoke smell into the insulation lining. In Oakland, fall Diablo winds push this smoke through eaves and returns, especially in hillside homes. A standard vacuum pass won’t remove it. The system needs agitation plus negative-air extraction, and often coil cleaning to kill the smell.
Yes, if the wrap is intact and accessible, we clean around it carefully using containment procedures that don’t disturb the material. If the wrap is fraying or the ducts are corroded underneath, we’ll tell you what we found before we recommend anything further. We don’t disturb material that should stay put. Call (361) 326-5060 and we’ll assess your specific duct chases.
Raccoons and squirrels chew through flex duct to get into the conditioned space or to nest in the attic. Once one section is torn, the pressure imbalance in the system makes it easier for them to get through the next run. We replace the damaged flex with a heavier-grade product and seal the connection points, then Oakland Dryer Vent Cleaning handles what the animals left behind.
Yes. The variable-speed blower reads airflow resistance continuously. When ash, debris, or animal damage restricts the ducts, the blower works harder or trips pressure switch faults. We clean the system and rebalance the blower so it operates within Carrier’s specs. That’s not something a generic duct cleaning crew thinks about because the error codes don’t mean anything to them.
Most Oakland homes benefit from a full duct cleaning every 3 to 5 years. Hillside homes in wildfire exposure zones may need it sooner, especially if you notice a persistent smoke smell. Flatland homes with attic wildlife may need cleaning any time you hear activity above the ceiling. Call (361) 326-5060 for an honest assessment of your system’s condition. Estimates are free.
