Why Bellows Air Duct & Vent Co. of California Is Palo Alto’s Preferred HVAC Cleaning Company
We’ve been serving Palo Alto homeowners since 1984, long enough to know that a house on Waverley Street in Crescent Park presents a different challenge than a 1970s ranch on Middlefield Road. Our reputation here was built on showing up with the right equipment for the job, not forcing standard tools into non-standard spaces.
Palo Alto customers call us back because we document every job with camera inspection before and after. No claim without proof. Our 90-Day Done Right Promise means if something’s not right, we return at no charge. No paperwork, no arguing. That’s been our policy for over 42 years.
Calls are answered by a live person, 24 hours a day. Not a voicemail, not an app. When you’re dealing with post-wildfire particulate or a blower throwing dust through a 1940s duct system, you want to talk to someone who can dispatch a technician, not leave a message and hope.
Our response time to Palo Alto is typically same-day or next-day. We route from our Los Angeles base with technicians who know the 94302, 94303, 94304, and 94306 ZIP codes well enough to find the narrow driveways and alley-access crawl spaces that GPS misses.
Our HVAC Cleaning Services in Palo Alto
Evaporator Coil Cleaning
The evaporator coil in your Palo Alto home’s air handler is where moisture meets dust, and in our climate, that meeting happens slowly and invisibly. Because Palo Alto’s Mediterranean weather means HVAC runs infrequently, coils can accumulate a thick blanket of debris before you notice reduced airflow. We clean coils with foaming treatment and low-pressure rinse, then verify with camera inspection. In older homes near Professorville, we often find coils coated with fine particulate from the 2018 Camp Fire smoke event, which simple dusting won’t remove.
Blower Cleaning
A dirty blower motor works harder, draws more power, and pushes debris back into your ductwork. In Palo Alto’s 1950s-1970s ranch homes, original blowers are often still running 50-70 years later, caked with layered dust and rust particles from corroding galvanized ducts. We remove the blower assembly, clean the housing, balance the fan, and reassemble. One visit. Most jobs take two to three hours.
Condenser Cleaning
Your outdoor condenser unit faces pollen from the oak and redwood canopy around Palo Alto’s western neighborhoods, plus the fine dust that settles during dry spells. We clean coils, straighten fins, check refrigerant lines, and verify electrical connections. For homes in Old Palo Alto with mature landscaping, we also clear debris from the pad and ensure adequate clearance for airflow.
Air Handler Cleaning
The air handler is the heart of your forced-air system, and in retrofitted Palo Alto homes, it’s often squeezed into a closet or attic space never designed for it. We clean the entire cabinet, replace filters, inspect drain pans for condensation-related mold, and treat with antimicrobial where needed. Camera inspection shows you the before and after.
Coil Treatment
After cleaning, we apply a specialized coil treatment that inhibits mold growth and improves heat transfer. In Palo Alto’s climate, where winter Bay humidity creates condensation in uninsulated duct runs, this treatment prevents the recurrence that makes homeowners call back six months later. It’s part of our standard service, not an upsell.

Common HVAC Cleaning Problems We See in Palo Alto Homes
- Convoluted retrofitted ductwork in historic neighborhoods. The 1920s-1950s homes in Professorville, Old Palo Alto, and Crescent Park were built for radiant heat or no central system at all. Forced-air ducts were threaded through crawl spaces around original floor joists in tight S-curves that trap debris and defeat standard cleaning equipment.
- Post-wildfire particulate from the 2018 Camp Fire. The smoke event that blanketed Palo Alto for nearly two weeks deposited measurable fine particulate deep into duct systems citywide. This residue requires HEPA vacuuming and specialized coil treatment, not just a basic brush-and-vac.
- Corroded galvanized duct joints in aging ranch homes. Midtown and South Palo Alto’s 1950s-1970s tract houses often retain original galvanized or early flex ductwork now 50-70 years old. Interior corrosion flakes off and circulates through the system, and separated joints pull attic or crawl-space air into the supply.
- Detached workshops with heavy-duty doors needing concurrent service. Many Palo Alto properties include outbuildings with 12-14 foot steel or wood overhead doors and specialized spring and opener systems. Homeowners who value one-trip completion need a crew equipped for both HVAC cleaning and heavy-door service.
Pricing for HVAC Cleaning in Palo Alto, CA
A typical evaporator coil cleaning in Palo Alto runs $280-$380. Full air handler and blower cleaning runs $350-$520. Condenser cleaning alone is $180-$260, or $450-$650 when bundled with full indoor system service. Coil treatment is included in our standard full-service package, not priced separately.
What moves the number: accessibility of your air handler (attic vs. closet vs. crawl space), condition of existing ductwork, whether post-wildfire particulate requires extended HEPA vacuuming, and if detached structures need concurrent service. We disclose the full price before lifting a single tool. The number on the phone is the number on the invoice.

FAQs - HVAC Cleaning in Palo Alto
The November 2018 Camp Fire deposited measurable fine particulate into duct systems across Palo Alto during a nearly two-week smoke event. This residue is finer than household dust and bonds to coil surfaces and duct interiors, requiring HEPA vacuuming and specialized coil treatment rather than standard brush cleaning. If your home was occupied during that period and hasn’t had professional duct remediation since, particulate likely remains in the system. Call (855) 401-6006 for a camera inspection and free estimate.
We use compact Rotobrush systems and hand-guided cleaning passes for the tight S-curve ductwork found under Professorville’s 1920s-1950s homes. Standard rotary equipment won’t navigate the geometry created when forced-air was retrofitted around original floor joists. These jobs typically add an hour or more to the schedule, and we price accordingly upfront, not at the door. Our technicians are background-checked and uniformed, and they carry drop cloths to protect your floors.
Yes. Many Palo Alto properties, particularly in Professorville and Crescent Park, include detached workshops with 12-14 foot steel or wood overhead doors requiring specialized spring and opener service. We cleaned the HVAC system in a 1941 Craftsman on Cowper Street in Professorville, where the homeowner’s detached workshop had a 14-foot steel garage door with a broken torsion spring. While our techs performed thorough air handler and coil cleaning inside the main house, they also replaced the spring and serviced the opener on the heavy-duty door, ensuring the entire property was serviced in one trip. Call (855) 401-6006 to discuss your property’s specific needs.
We clean and service all major brands found in Palo Alto homes, including systems with Honeywell and Aprilaire components. Our trucks carry Rotobrush and Nikro equipment for the cleaning itself, plus common parts for faster turnaround. For specialized components, we source from regional suppliers with next-day delivery.
