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 HVAC Cleaning Across Berkeley
HVAC cleaning in Berkeley means dealing with two things most other Bay Area cities don’t have to think about: a marine fog layer that keeps duct interiors damp for months, and a housing stock where half the homes predate 1950 and carry original sheet-metal ductwork wrapped in materials that now require testing before anyone touches them. We work in Berkeley every week, and we know which neighborhoods have the tightest crawl spaces, which era of construction tends to hide what, and how long it actually takes to do the job right here. If you’re dealing with musty air from your registers, reduced airflow, or coils caked in dust from years of fog-season humidity, call us at (806) 606-6902 for a written price before any work starts.
Why CleanRun Air Duct Cleaning Is Berkeley’s Preferred HVAC Cleaning Company
Our HVAC Cleaning team has worked extensively throughout Berkeley, from flatland Craftsman bungalows near Ashby BART to hillside Period Revival homes above the Claremont Hotel. We established the company in 2013, and since then we’ve served more than 52,000 homes, every single one with a written price delivered before work began and a documented photo record when the crew left. Berkeley customers tend to be specific about what they want: proof that the work happened, honest answers about what was found inside the ductwork, and no pressure to add on services that don’t address the actual problem. That’s how we operate.
What sets us apart here isn’t a slogan. It’s Haven Standard Clause 1: a written price before any work starts, no exceptions. It’s also the Documented Photo Record included on every visit, where inside every duct run is photographed before and after. If we find something unexpected, like a 3-inch debris build-up at the first elbow or deteriorated duct tape on a 1940s seam, you’ll see it for yourself before you approve anything. We don’t ask you to take our word for it. Tomas Reyes, who leads our team, insists on that standard on every job, and it’s why Berkeley homeowners keep our number.
Our HVAC Cleaning Services in Berkeley
HVAC cleaning isn’t one procedure. It’s a set of services aimed at different components of your forced-air system, and in Berkeley’s damp microclimate, some components need attention more often than inland homes do. Here’s what we do most frequently in Berkeley homes.
Evaporator Coil Cleaning
Your evaporator coil sits inside the air handler, and in Berkeley it’s often the single biggest airflow restriction in the system. Fog-season moisture condenses on the coil, and that wet surface grabs dust, pet hair, and whatever else moves through the return side. In Elmwood and North Berkeley homes where the air handler is tucked into a hall closet, a fouled coil can cut airflow enough that the system runs constantly without hitting the thermostat setpoint. Cleaning the coil properly means removing the access panel, inspecting the coil face with a camera, and using professional-grade equipment to pull the debris out rather than pushing it deeper into the fins.
Air Handler Cleaning
The air handler is the cabinet that houses the blower motor, the evaporator coil, and often the filter housing. In older Berkeley homes, these units are frequently retrofitted into spaces not designed for them, like basement crawl spaces or narrow utility alcoves off the kitchen. That makes access tight and cleaning slower. We clean the interior surfaces, remove accumulated debris from the blower housing, and document the before and after. If the air handler is original to a pre-1950 home, we also check for degraded insulation or asbestos-containing materials before any agitation starts, which is a step most companies skip.
Blower Cleaning
The blower wheel is what pushes conditioned air through your duct runs. In Berkeley, where systems often run year-round to manage humidity even when temperatures are mild, blower wheels accumulate a fine coating of dust that throws the fan out of balance and reduces efficiency. A dirty blower can also spread particles back into the air stream, which matters if anyone in the household has allergies or asthma. We remove the blower assembly where access allows, clean each blade, and reassemble it carefully. On hillside homes where clearances are tight, we use a camera to verify the wheel is clean before we button the cabinet back up.
Condenser Cleaning
Your outdoor condenser coil endures a different set of conditions in Berkeley: salt air from the Bay, pollen from the eucalyptus and oak canopy, and the fine dust that settles when the marine layer rolls in. A condenser coil packed with debris can’t reject heat efficiently, which means the system works harder and runs longer. We clean the condenser coil using professional-grade equipment, inspect the fins for damage, and clear the surrounding area so the unit can breathe. For Berkeley homes with the condenser tucked into a tight side yard or under a deck, we’ll always document the condition of the coil before we start so you can see exactly what we found.
Heat Exchanger Cleaning
On systems with a gas furnace, the heat exchanger transfers combustion heat to the air moving through your home. In Berkeley’s damp climate, a heat exchanger can develop surface corrosion over time, and accumulated dust on the exchanger surfaces can produce a smell when the furnace first fires each season. We clean the accessible surfaces of the heat exchanger as part of a full HVAC cleaning, and we’ll also confirm the exchanger is sound before we finish. If we see a crack or perforation, we’ll document it and recommend a qualified HVAC technician to evaluate, because that’s a safety matter, not a cleaning task.
Coil Treatment
After cleaning, we apply a coil treatment designed to help keep the evaporator and condenser coils cleaner between service visits. In Berkeley specifically, where the marine layer keeps coils damp for long stretches, this treatment can make a measurable difference in how quickly biological growth re-establishes on the coil surface. It’s not a substitute for cleaning, and we won’t pretend it is. But applied to a genuinely clean coil, it extends the interval between cleanings. If you’ve had a company fog your ducts with a sanitizer and the musty smell came back within a month, the coil was probably never actually cleaned. This is the step that addresses that.

BeforeAfterTrusted Brands We Service in Berkeley
We service all major HVAC brands found in Berkeley homes, including Carrier, Trane, Lennox, Rheem, Goodman, and Mitsubishi mini-split systems. Because Berkeley’s housing stock skews older, we also work on a fair number of legacy systems from brands that no longer exist or have been absorbed into larger manufacturers. For the cleaning work itself, our equipment roster includes Abatement Technologies, Rotobrush, and Nikro, which are professional-grade tools you can look up independently before you approve a price. If you have a written estimate from another company, bring it to us. We’ll put our own number next to it in writing, free of charge.
Common HVAC Cleaning Problems We See in Berkeley Homes
- Asbestos-containing duct wrap and tape on pre-1978 systems. Homes built before 1950 in Berkeley’s flatlands and hills often have original sheet-metal ducts sealed with asbestos-containing mastic or wrapped in asbestos tape. California abatement rules require testing before any agitation, which adds a step but keeps fibers out of your living space.
- Chronic mold colonization in damp, poorly sealed duct joints. Berkeley’s persistent marine fog keeps relative humidity elevated from the Elmwood to the Northbrae hills. Inside aging ductwork with loose joints and small leaks, that moisture never fully dries, allowing mold to establish and recolonize even after a fogging sanitizer has been applied. Fogging masks odor. It doesn’t remove the colony.
- Hillside crawl space access constraints. Homes above the Berkeley Rose Garden or in the Claremont hills often have crawl spaces with tight clearances and retrofit duct runs that snake through spaces never designed for them. Shoving equipment past these runs can damage original sheet-metal seams. It takes patience and the right tools to clean these systems without causing more damage.
- Heavily impacted ductwork in student rentals near campus. In the dense rental zone around UC Berkeley, forced-air systems in older multi-unit buildings often run continuously with filters that haven’t been changed in months. At tenant turnover in May and August, property managers discover duct runs packed with years of accumulated dust, debris, and sometimes worse.
Pricing for HVAC Cleaning in Berkeley, CA
We publish pricing ranges because that’s the entire point of Haven Standard Clause 1: a written price before any work starts. For HVAC cleaning in Berkeley, a full system clean typically runs between $390 and $780, depending on the number of air handlers, the complexity of access, and whether asbestos testing or abatement coordination is required. Evaporator coil cleaning as a standalone service in Berkeley runs $140 to $260 per coil. Air handler cleaning runs $120 to $230. Blower cleaning runs $100 to $190. Condenser cleaning runs $90 to $180. These are whole-system or whole-component prices, not per-vent teaser rates that balloon once the van is parked in your driveway. We don’t do per-vent pricing, and we don’t quote a low number that becomes a larger invoice after a bait-and-switch inspection. You’ll get one flat price per system before we touch anything. If another company’s written estimate comes in lower, bring it to us. We’ll put our number next to it in writing, and you decide.
Our pricing reflects reality in Berkeley’s market. The reason a $99 whole-house special exists is that it’s not a whole-house cleaning. It’s a visit designed to generate an upsell. In Berkeley specifically, with the legal requirement for asbestos testing on so many pre-1950 homes, the true cost of a safe, thorough cleaning includes steps that discount operators simply omit. We’d rather give you an honest number that reflects the actual work than a teaser rate that can’t possibly pay for the job being done correctly.

FAQs - HVAC Cleaning in Berkeley
Yes, if the ductwork is original and wrapped in materials that haven’t been tested, we cannot legally or safely agitate those ducts without asbestos testing first. Under California abatement rules, any work that could disturb asbestos-containing materials requires testing before agitation. Berkeley has thousands of pre-1950 homes with original sheet-metal ducts sealed with asbestos-containing mastic or tape. If we encounter suspected asbestos during our camera inspection, we pause source removal, coordinate testing, and proceed only when we know it’s safe. This adds time and cost, but omitting it is how fibers end up in your living space. Call (806) 606-6902 if you want us to explain what this looks like for your specific house.
Mold comes back because a fogging sanitizer only treats the air and the accessible surfaces at the time of application, not the microbial colonies embedded in damp, poorly sealed duct joints. In the Elmwood and other Berkeley neighborhoods under the marine layer’s influence, duct interiors stay damp for months at a time. If the cleaning didn’t actually remove the organic buildup and address the moisture entry points, the mold re-establishes within weeks. A genuine clean removes the debris, corrects the seal where possible, and documents what was done with before-and-after photos of every duct run. If you’ve had your ducts fogged and the smell returned, what you likely need is the source removal that wasn’t done the first time. Call (806) 606-6902 and we’ll put a written price in front of you.
We clean coils in tight spaces using professional-grade equipment designed for exactly this constraint: coil cleaning tools with angled wands, HEPA-filtered negative air machines, and inspection cameras that let us see what we’re doing without dismantling the closet wall. Berkeley hillside homes, particularly in the Claremont and north hills areas, often have air handlers retrofitted into spaces never designed for them. We work around the constraints, document the access before and after, and if the coil cannot be adequately cleaned in place, we’ll tell you that in writing and quote the additional work required to do it properly. We won’t pretend a partial clean in an impossible space is the same as a real coil cleaning. Call (806) 606-6902 to discuss your specific setup.
Because that’s when the student rental stock turns over. In the dense multi-unit buildings along Telegraph Avenue, Southside, and Northside, forced-air systems run continuously year-round, often with filters that haven’t been changed in months. Landlords and property managers discover heavily impacted ductwork at move-out, and the rush to make units rentable again creates a predictable spike in demand every May and August. If you’re a Berkeley property owner, scheduling your duct cleaning before the turnover rush in April or July will get you a faster appointment and a less chaotic process. Call (806) 606-6902 and schedule ahead.
NADCA, the National Air Duct Cleaners Association, sets the technical standard for how source removal cleaning should be performed, including the use of negative pressure and HEPA filtration to prevent contamination release during cleaning. For a Berkeley Mission Revival home with original ductwork, those standards matter because they govern how the system is protected while we work. We follow NADCA standards on every job, not because a badge says so but because the method is what makes a cleaning genuinely clean rather than a fogging exercise. If you want to know exactly what “cleaned to NADCA standards” means for your home’s ducts, call (806) 606-6902 and we’ll walk you through it.
