We’re Northstar Air Duct Cleaning Service San Francisco, and for 14 years we’ve focused on one thing: the air moving through your home. Brian Rivera — owner and lead technician — handles your job personally, not dispatched labor from a staffing app. That matters in a city where Victorians in Noe Valley have completely different duct configurations than the mid-century builds in Visitacion Valley, and where Pacific fog and salt air create corrosion patterns you won’t find inland. Our 1,209 verified reviews averaging 4.9 stars aren’t marketing numbers — they’re a track record built job by job, with Brian on every one.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Your home’s ductwork collects what your filters miss — construction dust from that 2023 kitchen remodel, pet dander, pollen that slips through during San Francisco’s extended spring, and the fine particulate that blows in from the Central Valley every summer. We clean the full supply and return network using Rotobrush contact cleaning and Nikro HEPA-contained extraction, not a shop vac with a brush attachment. Brian Rivera — owner and lead technician — handles your job personally, so the most experienced person in our company is the one crawling your crawlspace in the Sunset or accessing attic runs in Bernal Heights.
Commercial Duct Cleaning
Restaurants in Chinatown, dental offices near UCSF, and multi-tenant buildings in the Mission District face air quality regulations and liability concerns that residential jobs don’t touch. We bring Abatement Technologies commercial-negative-air machines and containment protocols that satisfy property managers and health inspectors alike. Our 14 years of focused experience means we understand how San Francisco’s commercial kitchen exhaust interacts with shared HVAC systems — a complexity generalist HVAC companies often underestimate.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, which means every particle clinging to their walls eventually lands on your furniture, your bedding, your lungs. In San Francisco’s older housing stock — think 1920s Marina District apartments with galvanized steel or the flexible ductwork retrofitted into SOMA lofts — supply lines are often the dirtiest segment because they’ve never been independently addressed. We isolate and clean each supply run with Rotobrush agitation and Nikro vacuum extraction, measuring airflow before and after to verify the improvement.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and because they’re under negative pressure, they’re dust magnets — especially in homes near construction zones, which describes half of San Francisco on any given Tuesday. Return trunks in basements and crawlspaces (common in Ingleside and Outer Richmond properties) often harbor mold from our persistent marine layer moisture. We treat these runs with the same commercial-grade equipment we deploy on remediation jobs, and we document the condition with video inspection before recommending any additional sanitizing.
Full System Cleaning
A full system cleaning addresses every component air passes through: supply ducts, return ducts, trunk lines, plenums, and the HVAC cabinet itself. This is what we recommend for San Francisco homes after major renovations, before listing a property for sale, or when occupants have documented respiratory sensitivity. We sequence the work to prevent cross-contamination, seal access points with code-compliant materials, and finish with Honeywell or Aprilaire air quality solutions if your system would benefit from ongoing treatment.
Video Inspection
We feed a self-leveling camera through your ductwork before and after cleaning, so you see what we’re dealing with and what we removed. In San Francisco’s competitive real estate market, this documentation protects sellers from last-minute inspection disputes and gives buyers confidence in what they’re inheriting. The video also reveals structural issues — disconnected flex duct in a Castro Victorian’s inaccessible chase, or rust perforation in a Sunset District home’s galvanized steel — that cleaning alone won’t solve.

Brands We Service for Air Duct Cleaning
We’ve cleaned ductwork connected to every major HVAC brand installed in San Francisco over the past two decades. Carrier and Trane systems dominate the newer construction in South Beach and Yerba Buena, and we’ve serviced hundreds of both — we know their plenum configurations and how to access their duct transitions without damaging proprietary fittings. Lennox and Bryant units are common in the Richmond and Sunset Districts’ 1990s-era replacements, and we stock the specific access panels and gasket materials these systems require for proper resealing after cleaning.
Rheem, Goodman, and York appear frequently in Mission District rentals and multi-family conversions, where deferred maintenance often means we’re cleaning decades of accumulated debris. We’ve also worked extensively with Mitsubishi ductless systems in Pacific Heights renovations and Haier units in Chinatown’s newer developments — these present unique challenges because their slim-duct configurations demand specialized brushes and camera equipment. Whether you have these makes or any other system, we can help, and we’ll tell you honestly if your ductwork condition exceeds what cleaning can remedy.
Signs You Need Air Duct Cleaning Right Now
- Visible dust blowing from vents when the system starts. If you see a puff of particulate every time your blower kicks on, your ducts are saturated beyond what your filter can manage. In San Francisco, this often follows renovation work — even with contractor cleanup, drywall dust and demolition debris find their way into returns.
- Persistent allergy or asthma symptoms that worsen at home. When your bedroom vents are circulating accumulated pollen, dust mite debris, and mold spores, your respiratory system pays the price. We’ve seen dramatic improvement after cleaning in homes near Golden Gate Park’s high pollen zones and in damp neighborhoods like the Excelsior where mold pressure is constant.
- Uneven heating or cooling with no mechanical explanation. If your thermostat reads 72 but your back bedroom in the Richmond never gets above 68, restricted airflow from duct buildup may be the culprit. We measure static pressure and airflow at each register to separate duct obstruction from equipment failure.
- Musty or stale odors when the system runs. San Francisco’s marine climate creates ideal conditions for microbial growth in ductwork, especially in homes with crawlspace or basement returns. The smell isn’t just unpleasant — it’s evidence of biological activity that standard cleaning may need to address with additional sanitizing.
- It’s been more than five years since your last cleaning — or you’ve never had one done. Previous owners don’t disclose duct maintenance, and many San Francisco properties have decades of neglect. If you’re in a pre-1970s home in Noe Valley or the Mission, there’s a strong chance your ductwork has never been professionally cleaned.
Our Air Duct Cleaning Process — Step by Step
- 1
On-site assessment and video inspection. Brian Rivera arrives at your San Francisco property, reviews your HVAC configuration, and feeds a camera through representative duct runs. We identify access points, note any damage or disconnected sections, and show you the pre-cleaning condition so you understand what we’re addressing.
- 2
System isolation and protection. We seal registers, protect flooring and furnishings, and establish negative air pressure at the HVAC cabinet using Nikro HEPA-contained equipment. This prevents debris migration during cleaning — critical in San Francisco’s compact homes where living space sits directly above mechanical areas.
- 3
Mechanical agitation and extraction. Rotobrush contact brushes loosen adhered debris from duct walls while simultaneous vacuum extraction captures it at the source. We size the brush to your duct diameter, whether that’s 6-inch flexible duct in a Sunset bungalow or 14-inch rigid trunk in a Pacific Heights estate.
- 4
Component cleaning and access sealing. We clean the blower assembly, evaporator coil (if accessible), and plenum; then seal all access points with code-compliant materials. In San Francisco’s seismic environment, we verify duct supports and connections haven’t loosened over time.
- 5
Post-cleaning verification and documentation. We run the video camera again, measure airflow at key registers, and provide you with before-and-after documentation. If we recommended sanitizing with Guardsman-grade products or air quality upgrades using Honeywell or Aprilaire equipment, we review those options without pressure.
How Much Does Air Duct Cleaning Cost in San Francisco?
A typical residential duct cleaning in San Francisco runs $350–$650 for homes under 2,500 square feet with accessible ductwork. Larger homes in St. Francis Wood or Sea Cliff with complex zoning systems, or properties requiring extensive crawlspace or attic access, typically fall in the $650–$850 range. Commercial jobs in the Financial District or multi-family buildings in the Mission District are priced per system after assessment, usually starting at $800.

Several factors move the needle. The number of supply and return vents matters more than square footage — a compact Russian Hill condo with 12 registers costs more than a Sunset District home with 8. Accessibility is huge in San Francisco: Victorian crawlspaces in Noe Valley, steep roof access in Bernal Heights, or parking-constrained locations in North Beach all add time. Post-renovation cleanings with heavy construction debris require more agitation passes and filter changes. We include all of this in our free, no-obligation estimate — no surprise charges after we’re on site.
How to avoid overpaying: beware of San Francisco companies advertising whole-house cleaning for under $250 — they’re typically bait-and-switch operations that upsell “extra” vents or use equipment no more sophisticated than a household vacuum. Ask specifically whether the owner will be on your job, what equipment brand they use (if they can’t name it, it’s not professional-grade), and whether they provide video documentation. Our estimate includes everything: all vents, trunk lines, video inspection, and post-cleaning verification. Call (855) 908-0725 for your exact quote — estimates are free, and Brian Rivera handles every assessment personally.

Frequently Asked Questions — Air Duct Cleaning in San Francisco
Air duct cleaning is the mechanical removal of accumulated dust, debris, allergens, and microbial growth from your HVAC ductwork and components. We remove what your filter can’t catch: construction dust, pet dander, pollen, mold spores, and the fine particulate that settles in duct corners and blower assemblies over years of operation. Our Rotobrush and Nikro equipment captures this debris at the source rather than redistributing it through your home.
A standard residential job takes 3–5 hours; larger homes or post-renovation cleanings may extend to 6–8 hours. We don’t rush — proper sequencing (isolation, agitation, extraction, verification) takes the time it takes, and we schedule only one job per day so your appointment isn’t squeezed between others. Call (855) 908-0725 to check availability for your preferred date.
Most San Francisco homes fall between $350–$650, with larger or more complex properties reaching $850. The final price depends on vent count, accessibility, and contamination level — not square footage alone. We provide exact pricing after a free on-site assessment, not a phone guess that changes on arrival.
Yes — we clean ductwork connected to Honeywell and Aprilaire air quality equipment regularly, and we can integrate their whole-home purifiers and ventilators into your system during the same visit. We also use Guardsman-grade products for sanitizing applications where microbial treatment is indicated. Call (855) 908-0725 to discuss your specific configuration.
We maintain same-day availability for urgent situations: post-renovation move-ins, real estate transaction deadlines, or acute allergy flare-ups requiring immediate intervention. True emergencies (fire restoration, water damage) are prioritized. Our 14 years in San Francisco means we understand when “next week” isn’t acceptable — call (855) 908-0725 and we’ll tell you honestly if we can accommodate your timeline.
We guarantee visible debris removal verified by post-cleaning video inspection, and we return at no charge if airflow measurements don’t meet our documented standards. We’re not satisfied until you can see the difference — that’s why 1,209 customers have left us a 4.9-star average. Specific warranty terms vary by service scope and are detailed in your written estimate.
Clear a workspace around your HVAC unit and ensure we can access all registers — move furniture, pet beds, or stored items blocking vents. We’ll handle floor protection and furniture covering once on site. If you have specific concerns about a particular room or vent, note them before we arrive so Brian can prioritize that area during video inspection. Call (855) 908-0725 with any questions — we’re happy to walk you through it.
