Fast, Reliable Air Duct Cleaning Across Mission District
Air duct cleaning in Mission District homes usually runs between $450 and $950 for a full system on a typical Edwardian flat or pre-1906 rowhouse, with inspections starting around $150. We’re in and out of 94110 on a regular basis, and we know what’s inside these walls because we’ve opened enough of them. If your ducts haven’t been touched in years, or you’re noticing dust that settles back on furniture within days of wiping it down, call (833) 620-5944 and we’ll walk you through what we’d check first.
The Mission District’s housing stock is not like the rest of San Francisco. We’re talking about dense rows of Victorians and Edwardians on 25-foot lots, shared party walls, and ductwork that was installed long before anyone thought about sealing joints or insulating crawlspaces. That changes what a cleaning actually involves here, and it changes what you should expect from any company you hire.
Why Everclear Air Duct Cleaning Is Mission District’s Preferred Air Duct Cleaning Company
We’ve worked in enough Mission District buildings to know that a flat on Guerrero and a rowhouse near Shotwell don’t present the same duct problems, even if they were built the same year. Gravity furnaces, retrofitted mini-splits, abandoned runs, disconnected boots under original hardwood floors – these are the things we expect to find before we even open an access panel. That local familiarity means we don’t waste your time figuring things out on the job; we start with a plan.
Led by Bruce Lowry, our crews bring Rotobrush rotary brush systems and Nikro HEPA-rated vacuum equipment into homes where the crawlspace is barely tall enough to turn around in. We don’t cut corners on containment because we’ve seen what happens when a cut-rate operator dislodges fifty years of dust and then leaves it drifting up through floor registers. Our approach is simple: capture the debris, don’t redistribute it.
Mission District customers routinely tell us the same thing when we finish: they can finally see the difference inside the duct, not just feel it in the air. That’s the whole point. If you can’t verify the work, you didn’t get what you paid for.

Ductwork Cleaning in Mission District
Ductwork Cleaning in Mission District is rarely a straightforward vacuum job, because the ducts themselves are rarely straightforward. Most of these systems were installed decades ago, then patched, extended, and partly abandoned as building owners added wall heaters or split systems. Our first step is always the same: map the runs, find the access points, and figure out what’s actually connected before we start agitating anything.
A full cleaning in Mission District includes supply and return ducts, boots, and plenums. We set up negative pressure at the return, run Rotobrush agitation tools through each accessible run, and pull everything into a Nikro HEPA-filtered collection unit. In a typical two-bedroom Edwardian flat, that takes most of a day – not the 45 minutes a bargain-rate outfit will promise over the phone.
Full System Cleaning
This covers every connected duct run, from the return drops to the furthest supply register. In Mission District homes with original galvanized ducts, we’re often the first crew those runs have seen since they were installed.
After cleaning, we inspect each section for cracks, disconnections, and crushed spots – issues that are more common here than in newer housing stock because the framing has settled and shifted for a century.
Supply and Return Duct Cleaning
Supply ducts carry the air you breathe into your rooms; return ducts pull it back. Both accumulate dust, but in Mission District crawlspaces, the return side often pulls damp air and fine particulate from below the house, which means it can be the grimier of the two.
We clean both sides on every job, and we check for return-side leaks that might be drawing unconditioned crawlspace air into the system.
Air Duct Inspection in Mission District
Air Duct Inspection in Mission District typically costs $150 to $350 and answers one question: what is actually inside these ducts, and what condition are they in? For older buildings, we recommend this before any cleaning, because what we find determines what the cleaning should cost and how long it should take.
We run a camera through accessible sections and document everything: crushed runs, disconnected boots, mold on the duct walls, debris accumulation, and signs of rodents. You get the footage. Not a summary of the footage – the actual video, so you can look at your own ductwork and know exactly what we’re talking about.
Video Inspection
Camera inspection is the single most useful tool we have for Mission District ductwork. It shows us what’s behind the walls, under the floors, and in the crawlspaces without ripping anything open.
We’ve found collapsed duct sections that were invisible from the outside, and we’ve found perfectly clean systems that didn’t need a full cleaning – just a good filter and some sealing. We’ll tell you which one you have, and we’ll show you the proof.
Pre-Cleaning Assessment
Before we quote a full-system cleaning, we assess the layout, access points, and condition of the runs. In rowhouses, that means checking party walls and shared chases too, because neighboring units often share duct paths through those common walls.
This assessment is where we identify crushed sections or mold problems that would change the scope of the job. It keeps the price honest – no surprises after the equipment is already running.
Trusted Brands We Service in Mission District
We use Rotobrush rotary brush systems and Nikro HEPA-rated vacuums on every Mission District job, because these are the tools designed for the kind of irregular, aging duct runs we encounter in pre-1906 and Edwardian buildings. For homeowners who want to go beyond cleaning, we stock and install Honeywell and Aprilaire filtration products – so if you want better air long-term, not just cleaner ducts today, we can handle it in the same visit. We don’t have to subcontract that work out, and we don’t have to schedule a second contractor. That’s full-system care from the inside out, and it’s the reason our Air Duct Cleaning service looks different from what you’ll get from a truck-and-vac outfit running a coupon special.
Common Air Duct Cleaning Problems We See in Mission District Homes
- Crushed or disconnected runs in crawlspaces. Shallow raised foundations under Edwardian flats leave almost no clearance, and duct runs get flattened when piers shift or when plumbing work is done carelessly. That means airflow drops to almost nothing in some rooms while dust leaks into the crawlspace.
- Condensation and mold from marine air. The Mission sits in a warmer, sunnier pocket of the city, but winter rains and persistent marine humidity still reach the uninsulated crawlspaces. Ducts sitting in that dampness grow mold on the interior walls, and standard cleaning won’t touch it without the right antimicrobial treatment.
- Cross-unit dust transfer through party walls. In 25-foot-wide rowhouses, duct chases and framing cavities are often shared between units. If one unit has never been sealed, dust and allergens migrate through the wall, so a neighbor’s cleaning job can change the air quality in your unit too.
- Legacy gravity furnace debris. Many Mission District homes never converted to forced air; they still rely on gravity furnaces with short, wide, often fully original ducts. These accumulate decades of fine dust and fibers, and the runs are typically too irregular for off-the-shelf cleaning tools.

FAQs About Air Duct Cleaning in Mission District
We don’t fight the layout; we work around it. Gravity furnace ducts are wider and shorter than forced-air runs, and they usually run directly from the furnace platform up through the walls. We access them through the registers and furnace cabinet, then use Rotobrush agitation tools sized for the run diameter. The cleaning works, but the bigger challenge is often access – which is why our crews are used to working in crawlspaces and behind original lathe-and-plaster walls. Call (833) 620-5944 and we’ll assess your floor plan directly.
The raised foundations under these buildings are shallow and uninsulated, so the air in the crawlspace sits close to the ground and stays damp through the winter rainy season. Metal duct walls cool down, moisture condenses, and mold grows on the dust that’s already caked inside. That’s why we treat mold with antimicrobial products during our cleaning instead of just vacuuming out the visible dust. If your ducts have been in there for decades, this is the most common reason the air quality in your unit is bad.
Yes, and we see it happen regularly. Party walls in 25-foot-wide lots often contain shared framing cavities that connect to both units’ duct systems. When we clean one side, we create pressure changes that can pull dusty air from the neighboring space if there are gaps – which is why we run negative pressure with HEPA filtration throughout the job. We also check for breaches in shared chases when both units are accessible. If your neighbor’s dust is leaking into your air, that’s a sealing problem we can fix.
We run a camera through each accessible supply and return run, checking for disconnections, crushed sections, mold, and debris. In pre-1906 buildings, we’re also looking for abandoned gravity furnace runs that were capped but never sealed, and for framing cavities being used as improvised return paths. The inspection typically runs $150 to $350 depending on the size of the system, and you get the video footage to review with us. That way, the decision about what to clean or repair is based on evidence, not a sales pitch.
We isolate each unit’s system before we begin, and we run the vacuum and negative pressure continuously. That prevents the work in one unit from pulling air through a neighboring unit’s registers or ducts. In multi-unit Mission District buildings, we also coordinate directly with the owner or property manager about shared runs, so cleaning one side of the building doesn’t blast dust into the other. Bruce Lowry has crews who do this regularly in three-flats and fourplexes throughout 94110 – call (833) 620-5944 to schedule a look at your building.
What We Found in a Mission District Edwardian Fourplex
On a recent job near Valencia and 24th, we found the original galvanized supply ducts buried in a six-inch crawlspace, with two runs crushed flat beneath a retrofit foundation pier and disconnected at the boot. After setting up negative pressure with HEPA filtration, we used Rotobrush agitation tools to clear decades of damp lint and mold, then sealed the crushed sections with Guardsman mastic and reconnected the boot – restoring balanced airflow to the upper flat and stopping the dust that had been migrating into the neighboring unit through the shared party wall.
That’s what duct cleaning in the Mission District actually looks like. It’s not a quick vacuum pass. It’s finding the failure points that have been hidden for decades and fixing them so the air in your home stops carrying whatever is under your floor. If you’re in a Victorian or Edwardian building in the Mission and you haven’t had your ducts inspected – or you had them “cleaned” by someone who never showed you what was inside – call us. We’ll show you the difference, and we’ll show you the video to prove it.
