Fast, Reliable HVAC Cleaning Across Berkeley
HVAC cleaning in Berkeley typically runs $280-$650 for a full system service, and our HVAC Cleaning team completes most jobs in a single visit. We answer calls live, day or night, and our technicians are usually on the road to Berkeley within two hours of your call.
We’ve been driving up to Berkeley from our Los Angeles base for over 42 years, and we know the city block by block. From the fog-dampened crawl spaces of the north Berkeley hills in 94707 and 94708 to the densely packed student rentals near Telegraph Avenue and the original Craftsman bungalows lining Oregon Street in 94703, we’ve cleaned ductwork in homes that other companies won’t touch. Berkeley’s housing stock is old, its geology is active, and its climate is stubbornly humid - three reasons why generic cleaning crews from out of town often miss what’s actually wrong.

Why Bellows Air Duct & Vent Co. of California Is Berkeley’s Preferred HVAC Cleaning Company
Berkeley homeowners don’t call us because we’re the cheapest. They call us because the last company quoted one price on the phone and charged another at the door. We don’t operate that way. Our no-hassle upfront pricing means the number we give you before we start is the number on the invoice. Period.
Our reputation in Berkeley is built on homes we’ve returned to year after year - the same families in Elmwood, Claremont, and the Gourmet Ghetto who remember when Roger Castañeda first started sending crews up from Los Angeles in the 1980s. Roger still oversees every aspect of the business, and his name is on the work.
Every job gets a camera inspection before and after. You see what we see. No claims, no trust-me language - just a visual record of what was in your ducts and what’s there now. Most Berkeley jobs finish in one visit. Our technicians are background-checked, uniformed, and they answer to a live person at our office 24 hours a day. Not a voicemail tree. Not an app.
And our 90-Day Done Right Promise applies to every Berkeley home we service. If it’s not right, we make it right. No paperwork, no arguing. We stand behind it.
Our HVAC Cleaning Services in Berkeley
Air Handler Cleaning
The air handler is the heart of your forced-air system, and in Berkeley it’s working harder than it should. Decades of seismic vibration from the Hayward Fault have loosened duct connections throughout the city’s pre-WWII housing stock, allowing unfiltered attic and crawl-space air to bypass your filter entirely and deposit debris directly onto the blower wheel and housing. We disassemble the air handler cabinet, clean the blower assembly with professional-grade equipment, and inspect the housing for corrosion - common in hill homes where the marine layer keeps humidity elevated for months.
A typical air handler cleaning in Berkeley runs $320-$480. We bundle this with full duct cleaning for homes in 94707, 94708, and 94709 where access is complicated by steep-slope construction and crawl-space entries.
Evaporator Coil Cleaning
Berkeley’s persistent fog and north-facing hillside homes create conditions we don’t see in drier inland cities. Evaporator coils in homes near Grizzly Peak Boulevard or in the shaded canyons of 94708 often carry a biological film that restricts airflow and drives up energy bills. We use foaming cleaners and low-pressure rinses that won’t damage delicate aluminum fins, then verify performance with before-and-after temperature readings.
Evaporator coil cleaning in Berkeley typically costs $240-$380 as a standalone service, or $180-$260 when bundled with a full system clean. If your coil hasn’t been accessed in five or more years, expect it to need more than a surface wipe.
Coil Treatment
After cleaning, we apply a coil treatment that inhibits biological regrowth - particularly important in Berkeley’s damp microclimates. The marine layer that rolls through the Golden Gate doesn’t stop at the waterline; it pushes deep into Berkeley’s hills, and homes without adequate crawl-space ventilation stay wet enough to recontaminate cleaned coils within a season. Our treatment isn’t a coating that traps debris; it’s a time-release application that keeps the surface hostile to mold and mildew.
Coil treatment adds $85-$140 to any coil cleaning in Berkeley. We recommend it for homes in 94707 and 94708, and for any property with a history of musty odors at startup.
Blower Cleaning
The blower wheel moves every cubic foot of air your system conditions. When it’s coated with dust and debris - common in Berkeley’s older homes where original ductwork has never been properly sealed - airflow drops, motors overheat, and your utility bills climb. We remove the blower assembly, clean it off-site if necessary, and rebalance the wheel before reinstalling. In student rentals near UC Berkeley, where filters are rarely changed and systems run continuously, we’ve pulled blower wheels that were 40% obstructed.
Blower cleaning in Berkeley runs $180-$290. Combined with air handler cleaning, the pair typically costs $420-$580.
Condenser Cleaning
Berkeley’s outdoor condensers face a unique challenge: the same marine layer that cools the city also deposits salt and particulate on coil fins, accelerating corrosion. Add in the fine ash from annual wildfire seasons that settles on outdoor equipment, and condensers in the hills often operate at reduced efficiency within two years of installation. We straighten fins, clean coils with non-acid foaming agents, and clear debris from the cabinet base.
Condenser cleaning in Berkeley costs $150-$240. We recommend annual service for homes with units exposed to direct fog paths or recent wildfire smoke.

Trusted Brands We Service in Berkeley
We maintain equipment from Nikro, Honeywell, and Aprilaire - the same brands that serious HVAC contractors specify for Berkeley’s demanding conditions. Our technicians carry common replacement parts for these systems, which means most Berkeley jobs don’t wait on a parts run. If your air handler uses a Honeywell electronic air cleaner or your system includes an Aprilaire humidifier integrated with ductwork in a 94705 hillside home, we’ve serviced it before. We know the access panels, the fastener types, and the common failure points. That familiarity saves time, and we pass that through to you in the form of single-visit completions.
Common HVAC Cleaning Problems We See in Berkeley Homes
- Seismic loosening of duct joints. The Hayward Fault runs directly beneath Berkeley, and its constant micro-movements - fault creep you can’t feel - gradually loosen duct connections in wood-frame homes built before 1945. Gaps draw in cellulose insulation, vermiculite, and rodent debris from attics and crawl spaces. We find this in homes from the flats to the hills, and we seal with mastic before cleaning.
- Persistent damp in hill crawl spaces. Berkeley’s marine layer keeps relative humidity elevated in north-facing homes, particularly in 94707 and 94708. Uninsulated duct runs in these crawl spaces grow biological contamination that standard vacuuming won’t address. We treat with antimicrobial applications and recommend insulation upgrades where appropriate.
- Legacy Tunnel Fire ash residue. Homes in 94708 and 94709 that survived the 1991 Oakland-Berkeley Tunnel Fire structurally often had ductwork saturated with smoke and ash. Thirty years later, that residue still circulates. We encounter it regularly, and it requires HEPA vacuum extraction - not standard cleaning - to fully remove.
- Deferred maintenance in converted student housing. The rental stock near campus in 94704 and 94703 rarely sees professional duct attention between tenants. Systems run continuously, filters are neglected, and accumulated debris gets compacted into nearly solid mats. These jobs take longer, but they’re some of the most dramatic before-and-after results we document.

FAQs - HVAC Cleaning in Berkeley
Yes. The Hayward Fault produces constant micro-movements called fault creep that gradually loosen duct joints in Berkeley’s older wood-frame homes, creating gaps that pull in insulation fibers and debris. You won’t feel these movements, but your ductwork absorbs them daily. In a 1920s Craftsman on Oregon Street (94703), we found original duct joints shaken loose by fault creep, drawing cellulose insulation into the supply plenum - we sealed the joints with mastic and installed a Rotobrush cleanout. If your home was built before 1945, we recommend a camera inspection to check for seismic damage. Call (855) 401-6006 for a free estimate.
Yes, and urgently if it has never been done. Homes in 94708 and 94709 that survived structurally often had ductwork saturated with smoke and ash for weeks of smoldering; that contamination circulates fine particulate decades later, and standard filters won’t capture it. We encounter this legacy residue regularly and remove it with HEPA vacuum extraction. Call (855) 401-6006 to schedule an inspection - estimates are free.
Berkeley’s persistent marine layer and afternoon Bay fog keep interior humidity higher than inland East Bay cities, especially in north-facing hillside homes in 94707 and 94708 that receive minimal direct sun. Crawl spaces stay damp well into summer, and uninsulated duct runs provide the surface and moisture mold needs. Oakland and Richmond warm faster and dry sooner. If your Berkeley home smells musty when the system starts, that’s likely biological growth. Call (855) 401-6006 for a camera inspection and exact quote.
Repair if the damage is limited to accessible joints and the duct material is intact; replace if you have extensive corrosion, asbestos-containing material, or ductwork that has been disconnected by seismic shifting and cannot be resealed. In Berkeley’s pre-WWII housing stock, we often find that partial replacement of the most damaged runs, combined with thorough sealing of remaining joints, gives the best value. We’ll show you camera footage of your specific system and recommend accordingly - no pressure, just the facts. Call (855) 401-6006 to schedule.
Cleaning removes smoke particulate that has settled in your ductwork, but it won’t prevent future smoke intrusion - that’s a sealing issue. After Northern California wildfire seasons, fine particulate enters Berkeley homes through gaps in ductwork, especially seismic-loosened joints, and continues circulating long after outdoor AQI returns to normal. We clean with HEPA equipment and then identify the entry points so you can address sealing separately. For persistent smoke issues, ask about our coil treatment and air quality services. Call (855) 401-6006 for an estimate.
