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.

That’s how our Air Duct Cleaning team works in every neighborhood from the Berkeley Hills to the flats. We serve the whole city with professional-grade Rotobrush and Nikro equipment, and you’ll get a written quote before any work begins.

Why Cardinal Air Duct Cleaning Is Berkeley’s Preferred Air Duct Cleaning Company
Our Berkeley customers keep calling us back because we treat their older homes with the respect those houses deserve. A 1915 Craftsman in North Berkeley is not the same job as a 1980s condo in Emeryville. We know that. Our techs spend the time to map out the actual duct runs before they start, especially in crawlspaces and attics that haven’t been opened in decades.
Every booking runs through The Relay Standard. That means you get a live trackable arrival window, before-and-after photo documentation of the actual work performed, and a digital invoice you can pay from your phone. No vague “sometime between 8 and 2” windows. Omar Haddad leads the Berkeley crew, and he holds every tech to a simple standard: show up when you said, explain what you found, charge what you quoted.
We’re part of the Relay Home Co. family, founded in 2005, and we back every job with the 365-Day Done Right Promise. If the work isn’t right within a full year, we return and correct it at no charge. That’s not a marketing tagline. It’s written into every job.
Air Duct Cleaning Services in Berkeley
Air Duct Cleaning Services in Berkeley means working with systems that were often pieced together over multiple decades. We clean supply ducts, return ducts, and the main trunk lines, finishing with a video inspection so you can see the result on screen. Most standard single-system homes in Berkeley run $450 – $750, depending on home size and duct accessibility.
Residential and Full System Cleaning
For homes across the Berkeley flats, the Elmwood, and up into the Claremont hills, we run a negative-pressure extraction setup. That means we seal the system, connect a HEPA-filtered vacuum, and agitate the duct walls so debris goes straight into containment rather than back into your living room. A standard single-zone home takes about three to four hours.
Video Inspection Before and After
Before we quote any work, we scope the system with a camera. On older Berkeley homes, this often turns up disconnected runs, crushed flex duct, or framing debris from a past remodel inside the lines. You see the photos. You decide what gets done. No pressure.

HVAC Duct Cleaning in Berkeley
HVAC Duct Cleaning in Berkeley is about more than the registers you can see. It’s the full path air travels: return grilles, plenum, coil side, supply trunks, and every branch run. In a typical Berkeley home from the 1920s or 1930s, sections of that path may date from completely different eras. That’s exactly why we walk the whole system before pricing anything.
Return and Supply Side Work
Return ducts in older Berkeley houses often draw air from crawlspaces that were never properly sealed. We check for gaps, missing boots, and loose connections at the air handler. Once everything is tight, we clean and sanitize both sides using Abatement Technologies containment and HEPA extraction.
When Your HVAC Actually Needs It
Berkeley’s mild coastal climate means your HVAC runs fewer hard heating or cooling days than, say, Walnut Creek. That’s exactly why you might only need a full cleaning every three to five years, not annually. We’ll tell you when it’s not time yet. Honesty is cheaper for you and better for us in the long run.
Trusted Brands We Service in Berkeley
We maintain and clean systems from all major manufacturers, including Honeywell filtration setups, Aprilaire media cabinets, and Guardsman UV and filtration products. If your Berkeley home runs a multi-zone system or has a standalone ADU duct run behind the main house, we’ll assess both zones separately and give you one flat price for the whole property. We carry common filter sizes and access panels on the truck, which means most jobs finish in a single visit without a parts run across the bridge.
Common Air Duct Cleaning Problems We See in Berkeley Homes
- Piecemeal retrofits from knob-and-tube era homes. Many pre-1940 houses in Berkeley got forced-air systems added decades after they were built. The old gravity furnace runs were often reused, creating a duct system that is three different eras welded together.
- Uneven dust accumulation by room. Berkeley’s mild summers and foggy mornings mean HVAC runs cycle gently but unevenly. You’ll see heavy buildup in the branch runs serving one side of the house while other runs stay relatively clear. A flat per-vent quote punishes you for that pattern.
- Crawlspace disconnects hidden behind lath and plaster. It’s common on Elmwood and West Berkeley bungalows to find a return duct that pulled loose from the boot, drawing unfiltered crawlspace air for years. A camera inspection finds it. A shop-vac cleaning never does.
- Low-bid shop-vac shortcuts. Some Berkeley homes have tight attics or steep hillside crawlspaces that make real negative-pressure work take longer. A cheap contractor with a brush and a portable vac will stir debris instead of containing it, leaving your house dustier than before.
Pricing for Air Duct Cleaning in Berkeley, CA
A standard single-system air duct cleaning in Berkeley runs $450 – $750 for most homes. If you have a finished attic with inaccessible duct runs, a separate ADU zone, or a crawlspace with low clearance, expect the upper end of that range or slightly above. We do not charge per vent. You get one flat price per system, written down and handed to you before any work starts. Camera inspection is included. Sanitizing fog or UV filter installation costs extra and we’ll quote it separately if you ask. Call (737) 727-2314 and Omar Haddad will give you an honest range over the phone in about ten minutes.
We were called to a 1920s bungalow in the Thousand Oaks neighborhood where the owner had been dusting daily. Our techs ran a camera and found the original octopus gravity furnace ductwork had been partially reused when a modern forced-air system was added, a classic Berkeley retrofit. We set up negative pressure with HEPA, agitated the supply and return ducts, replaced a cracked boot at the air handler, and showed the homeowner exactly what came out. Before-and-after photos told the whole story.

FAQs About Air Duct Cleaning in Berkeley
Every three to five years for most homes. Berkeley’s climate is gentler on HVAC than inland cities, so buildup happens slower. If you have pets, recent remodeling dust, or an older system with visible dust at the registers, you might need it sooner. Call us at (737) 727-2314 and we’ll help you figure out if you actually need cleaning or if your system is fine.
Flat price per system. Always. We walk the whole property, check the duct layout, and give you one written price before we start. No per-vent math, no add-ons at the door. The price we quote is the price you pay.
We seal each register, connect a HEPA-filtered negative-pressure vacuum to the system, then run rotating brush agitation through every supply and return run. Debris is pulled to containment, not pushed into your rooms. We finish with a camera walkthrough and photos of the before-and-after.
Duct cleaning is a scheduled service, not an emergency. We book by appointment with a live trackable arrival window through The Relay Standard. Most Berkeley jobs get scheduled within two to four business days. Call (737) 727-2314 and we’ll get you the earliest real slot.
Yes, and we plan for it. Pre-1940s Berkeley homes often have duct runs retrofitted through old gravity furnace chases, tight attics, or low crawlspaces. That can add time and affect access. We’ll camera-inspect first, explain what we find, and adjust the flat price before any work starts. No surprises after we’re already in the crawlspace.
