General
How much does air duct cleaning cost in the Bay Area?
Our air duct cleaning costs $349 for up to 10 vents and $19 for each additional vent, the same price in every city we serve. A typical 3-bedroom home with 10 to 14 vents is $349 to $425. Dryer vents are $129 side-by-side, range hoods $169, a chimney sweep is $149 per flue, and bathroom fans are $99 each.
Which areas do you serve?
The whole San Francisco Bay Area from our base in Cupertino: Santa Clara County, San Mateo County, Alameda County, Contra Costa County, San Francisco, Marin and Santa Cruz County. Same-day available, and same-week appointments are normal within 30 minutes of Cupertino. Further out we group visits by area.
How do I book?
Call (781) 530-7642 any day between 7am and 7pm, or use the Book online button. We count vents with you, confirm the price on the phone, and hold a slot. No deposit, no payment until the job is done.
Do you clean the furnace or air conditioner?
No. We clean the ductwork, trunk lines, plenums we can reach and the register covers. The blower and coil inside the furnace are a separate service. We check your filter and tell you what we see.
What is the 10% off for new customers?
Ten percent off the total on your first visit, any service, when you mention the website. It applies to the whole invoice including additional vents.
Pricing
Is tax included in the price?
Yes. The prices on this page are what you pay. There is no fuel charge, no per-system charge, and no travel fee anywhere in the Bay Area.
How does the 10% new customer discount work?
Mention the website when you book and we take 10% off the total on your first visit, any service, including additional vents. One use per household.
Can I bundle services on one visit?
Yes, and most people do. Air ducts plus a dryer vent is the most common pairing. Each service is its own line at its listed price, and the 10% new-customer discount applies to the whole invoice.
When do I pay?
After the work, once you have seen what came out. Card, cash or check. No deposit to book.
Why is there no price for commercial?
Because a 1,200 square foot dental office and a 20,000 square foot warehouse are not the same job. We walk the space for free, count the air handlers and diffusers, and send a written price the same day.
Air Duct Cleaning
How much does air duct cleaning cost?
Air duct cleaning costs $349 for up to 10 vents and $19 for each vent past ten. Count every supply register and return grille in the house to get your number. A 2-bedroom condo with 7 vents is $349. A 4-bedroom house with 16 vents is $463. There are no fuel charges or per-system add-ons, and the price you get on the phone is the price on the invoice unless the vent count changes.
How long does air duct cleaning take?
Plan on 2 to 4 hours for a typical single-family home. A small condo can take 90 minutes. A large two-story home with two systems and 20-plus vents can take most of a day. We give you a time estimate when we confirm the vent count.
Do you clean the furnace too?
No. The $349 service covers the ductwork, trunk lines, plenums we can reach, and the register covers. The blower and evaporator coil inside the furnace are a separate job. We check your filter and tell you what we see.
What does a vent count as?
Every supply register and every return grille counts as one vent. A return is the large grille, often in a hallway ceiling or wall, where air gets pulled back to the furnace. Most homes have 1 or 2 returns and 8 to 14 supplies.
How often should air ducts be cleaned?
Every 3 to 5 years for most Bay Area homes, sooner after a remodel, a rodent problem or a heavy smoke season. There is no rule that fits every house. If you pull a register and the first foot of duct is clean, you can wait.
Will duct cleaning make a mess in my house?
No. The vacuum keeps the system under negative pressure, so loosened dust travels to our collection drum instead of out the registers. We put drop cloths at every opening and wipe down the register areas when we are done.
Can you clean flex duct?
Yes. Flex duct gets air whips instead of hard brushes so the inner liner is not torn. If a flex run is crushed, kinked or disconnected in the attic we will show you a photo and tell you what a repair would involve.
Do you use chemicals or sanitizers in the ducts?
No. We clean mechanically with vacuum and agitation. We do not spray sanitizers or deodorizers into ductwork.
What if my ducts are the old cement-board kind?
We stop. Cement-board and some paper-wrapped ducts in homes built before 1980 can contain asbestos, and agitating them is the one thing you should not do. Get a sample tested first. If it tests clean, we clean it.
Is duct cleaning worth it?
It is worth it when there is something in the ducts to remove: remodel dust, rodent debris, years of buildup, or a smoke season that coated everything. It is not worth it on a 3-year-old house with clean registers. Pull one register cover and look. We will tell you the same thing on the phone.
Dryer Vent Cleaning
How much does dryer vent cleaning cost?
Dryer vent cleaning costs $129 for a side-by-side washer and dryer and $179 for a stackable or closet unit. Both prices cover the full run from the dryer outlet to the exterior hood, clearing the hood, reconnecting the dryer and an airflow check. There is no extra charge for long runs or roof terminations we can reach.
How long does dryer vent cleaning take?
About 45 to 75 minutes. Short wall runs are done in under an hour. Long attic runs to the roof, or stackable units in tight closets, take closer to 90 minutes.
How often should a dryer vent be cleaned?
Once a year for a family that runs the dryer most days, every two years for light use. Long runs with several elbows and any home with a roof termination should stay on the yearly schedule.
Why does a stackable unit cost more?
Stackables sit in closets with a few inches of clearance. Pulling the unit out safely, reaching the transition duct, and reseating it takes about twice the handling time of a side-by-side, so we charge $179 instead of $129.
Can a clogged dryer vent cause a fire?
Yes. Lint is flammable and the heating element is right next to where it collects. Dryer fires are a well-documented cause of house fires, and a blocked vent is the usual reason. Cleaning the run removes the fuel.
My dryer still takes forever after cleaning. Why?
If we cleaned the run and confirmed airflow at the hood, the remaining problem is inside the dryer: a failing heating element, a worn blower wheel or a blocked internal lint path. That is an appliance repair, and we will tell you so at the visit rather than charge for a second cleaning.
Do you replace the foil duct behind the dryer?
We reconnect the existing transition duct if it is in good condition. If it is crushed, torn or the thin foil accordion type, we will tell you and can install a replacement for the cost of the part.
Do you clean dryer vents in apartments and condos?
Yes. Condo runs are often the longest in the Bay Area because the vent has to reach a roof or a shared wall. We coordinate with your HOA if roof access is needed.
Kitchen Exhaust & Range Hood Cleaning
How much does range hood cleaning cost?
Residential range hood and kitchen exhaust cleaning costs $169. That covers filter degreasing, the hood interior and fan, and clearing the exhaust duct to the exterior cap. Commercial and restaurant hoods are priced after an in-person visit because the duct length, fan and grease load vary too much for a flat rate.
How long does it take?
About 60 to 90 minutes for a standard wall-mount or under-cabinet hood. Island hoods and long duct runs to the roof take closer to two hours.
Do you clean recirculating hoods?
Yes. Recirculating hoods have no duct to the outside, so the job is the filters, the housing and the fan. We do not include the replacement charcoal filter, but we will tell you which one to buy.
How often should a range hood be cleaned?
Filters should be washed monthly at home. The full hood, fan and duct cleaning makes sense every 1 to 2 years for a household that cooks daily, and every 2 to 3 years for lighter use.
Can I just wash the filters myself?
Yes, and you should. The reason to call us is the parts you cannot reach: the fan blades or blower wheel, the grease channels inside the hood, and the duct run behind the wall or above the ceiling.
Do you clean restaurant hoods?
Yes, under our commercial service. Restaurant hoods, ducts and rooftop fans are quoted after a site visit, and we schedule around your closing hours. See the commercial page for what a visit covers.
Is a greasy range hood a fire risk?
A greasy hood is a fire risk. Grease in the hood and duct is fuel sitting directly above the cooktop, and a flare-up can ignite it. Keeping the filters, fan and duct clean removes the fuel.
Chimney Sweep
How much does a chimney sweep cost?
A chimney sweep costs $149 per flue. That covers the firebox, smoke shelf, damper, a full flue sweep under vacuum and a visual check. A second flue on the same property, for a second fireplace or a wood stove, is another $149.
How long does a chimney sweep take?
About 45 to 60 minutes for a standard fireplace. Heavily glazed flues or tall two-story masonry chimneys can take 90 minutes.
How often should a chimney be swept?
Once a year if you burn regularly through the winter, and before the first fire after a long break. If you burn a few times a year, every two seasons is fine as long as the smoke shelf looks clean.
Will sweeping make a mess?
No. The fireplace opening is sealed and a vacuum runs the entire time, so soot goes into the vacuum instead of the room. We clean the hearth before we leave.
Do you inspect the chimney?
We do a visual check of the firebox, flue interior and cap where we can reach them, and we tell you plainly what we see. We do not run a camera, so for a real estate transaction or a suspected crack you need a Level 2 inspection from a chimney inspector.
Can you fix a broken damper or missing cap?
No. We do not do chimney repairs. We will show you the problem and you can bring in a mason or chimney contractor.
Do you clean gas fireplaces?
No. Our $149 sweep is for wood-burning masonry and prefab fireplaces. Gas units need a gas fireplace technician.
Bathroom Fan Cleaning
How much does bathroom fan cleaning cost?
Bathroom fan cleaning costs $99 per fan. That covers the grille, the blower wheel and housing, the accessible duct to the roof or wall cap, and a run test. Two fans are $198, three are $297, all on one visit. Most people add it to an air duct or dryer vent appointment, and the price is the same either way.
How long does bathroom fan cleaning take?
About 30 to 45 minutes per fan. A fan with a short run to a wall hood is on the fast end. One that vents through the attic to a roof jack we can reach takes closer to 45 minutes.
How often should a bathroom fan be cleaned?
Every 2 to 3 years for a family bathroom that gets daily showers, and every 3 to 5 years for a guest bath or powder room. If the grille looks furry or the mirror has started staying fogged, it is due.
Do you clean every bathroom fan in the house?
Yes, and that is the usual call. Each fan is its own line at the same price, done on the same visit. Tell us how many bathrooms have a fan when you book so we plan the time.
What if my fan vents into the attic instead of outside?
We still clean the fan, and we tell you what we found. A fan that dumps warm wet air into the attic grows mildew on the roof sheathing over time. Running a duct to a roof jack is a contractor job, and we can describe what it involves, but we do not install it.
Can you replace a bathroom fan?
No. We clean the fan you have. If the motor is dead or the bearings are loud with a clean wheel, we tell you the fan is at the end of its life and you or an electrician swap it. There is no charge beyond the cleaning for that opinion.
Do you clean laundry room and utility fans too?
Yes, the same way and the same price. A ceiling exhaust fan in a laundry room, half bath, or utility closet counts as one fan.
Why does my bathroom still smell musty after cleaning?
If the fan is pulling well at the grille and the cap outside, the smell is coming from somewhere the fan does not reach: grout, a slow leak, or a wet subfloor. We will tell you the fan is fine so you can look elsewhere instead of paying for a second cleaning.
Is a dusty bathroom fan a fire risk?
It can be. Dust and lint packed around a fan motor hold heat, and product safety recalls over the years have involved bathroom fan motors that overheated. Cleaning the wheel and housing removes the fuel, and we tell you if the motor runs hot with a clean wheel.
Can I clean the bathroom fan myself?
You can wash the grille yourself and you should. The blower wheel, the fan box and the duct above the ceiling are the parts that need the vacuum and the brushes, and the roof or wall cap is where the blockage usually sits. That is the part we do.
Commercial Air Care
How much does commercial duct cleaning cost?
Commercial duct cleaning is quoted after a free on-site walkthrough. The price depends on the number of air handlers, the count of diffusers and returns, duct length, ceiling access and whether there is a kitchen exhaust system. You get a written quote, usually the same day as the visit.
What kinds of buildings do you clean?
Offices, medical and dental suites, laboratories, restaurants, retail, small warehouses and multi-unit residential buildings. The photos on this page are from a medical laboratory in Santa Clara County.
Can you work after hours?
Yes. Nights, weekends and holiday shutdowns are all normal for us, and there is no surcharge. Most office and medical jobs happen after 6pm or on a Saturday.
Do you clean restaurant kitchen exhaust hoods?
Yes. Hood, filters, plenum, the accessible duct run and the rooftop exhaust fan, with before and after photos. We schedule after closing so the line is cold.
Do you provide documentation?
Yes. Every commercial job gets before and after photos and a written summary of what was cleaned and anything we found that needs a contractor.
Service area
Do you charge a travel fee for cities far from Cupertino?
No. Air duct cleaning is $349 for up to 10 vents whether you are in Cupertino or Walnut Creek. Farther cities get grouped with other jobs in the area, which can mean a few more days of lead time, but the price is the same.
