Frequently Asked Questions - Air Duct Cleaning in Palo Alto, CA
Straight answers to the questions Palo Alto homeowners ask us most about air duct cleaning, from real costs to how the process works. If you don't see your question here, call us at (833) 620-7085 and we'll talk it through.
Pricing & Cost FAQs
A whole-system air duct cleaning in Palo Alto typically runs between $450 and $900 for a standard single-family home, depending on the size of the home, the number of vents, and how much buildup is in the system. Larger homes in neighborhoods like Old Palo Alto or the foothills near Los Altos Hills can run higher. We give you one flat price per system before any work starts, so the number we quote is the number you pay. No per-vent pricing games, no surprise add-ons once the equipment is in your driveway.

Bait-and-switch pricing is the biggest problem in this industry, and we hear about it constantly from homeowners in Menlo Park and Mountain View. A company advertises a low teaser price, then once they're in the home they claim the system has "extra vents" or needs "special sanitizing" and the invoice triples. A legitimate whole-system cleaning with commercial-grade agitation equipment and real HEPA collection simply costs a certain amount to do correctly. If a quote seems too low, ask what exactly is included and whether the price is for the entire duct system or "per vent."
We charge one flat price per system, agreed to before we start. Per-vent pricing is how some companies hide the real cost. You might be told "$29 per vent" and not realize your Palo Alto home has 25 vents until the bill arrives. Our estimate covers the entire duct system: supply and return lines, the main trunk, and all accessible vents. That's the honest way to price the job, and it's one reason homeowners in San Mateo and Redwood City call us back when they need us again.
Home size, the number of vents, how long it's been since the last cleaning, and whether the ducts are easily accessible all affect cost. Older homes in Downtown Palo Alto or Professorville often have tighter crawl spaces or basement-level ductwork that takes more time to access. Homes in Woodside and Portola Valley with larger square footage and longer duct runs naturally cost more than a two-bedroom condo in East Palo Alto. We consider all of this when we build your estimate, and we walk you through it before you sign anything.
For most Palo Alto homes, yes, especially if the ducts haven't been cleaned in five or more years, anyone in the household has allergies or asthma, or you've recently completed renovation work. Bay Area dust, wildfire ash from seasons like 2020, and pet dander accumulate in ductwork and recirculate through the home every time the system runs. Clean ducts also let the HVAC system move air more efficiently, which matters during Peninsula summers when air conditioning runs hard. If you're seeing dust return to surfaces quickly after cleaning, that's a sign the ducts are the source.
Service & Process FAQs
We use commercial rotary brush equipment, like systems from Rotobrush and Nikro, combined with high-powered negative-air HEPA collection to dislodge and remove debris from supply and return ducts. The process typically includes cleaning the main trunk lines, branch ducts, and all accessible supply and return vents. We also clean the return-air plenum. The goal is to remove the accumulated dust, hair, and debris from the entire system, not just the visible vent openings.
For a typical single-family home in Palo Alto, the full process takes between three and five hours. Larger homes or systems with significant buildup can take longer. We set aside a full morning or afternoon for the job so we never rush. You don't need to leave the house during the cleaning, though some homeowners prefer to run errands while we work. We'll give you a realistic time window when you schedule.
Not much. We ask that you clear access to the furnace or air handler and move any furniture blocking the main vents we'll need to reach. The equipment we use is portable and doesn't require major room clearance. Most Palo Alto homeowners find the preparation takes ten minutes or less. We'll tell you anything specific during the scheduling call.
It shouldn't. We use negative-air HEPA collection systems that pull the dislodged debris out of your ducts and into a sealed containment unit rather than blowing it back into your living space. Drop cloths protect the area around the furnace and vents. When we're done, you'll be able to see the difference in the before-and-after photos we take of your actual ducts, not stock images.
We use commercial-grade rotary brush agitation systems and high-powered HEPA collection, including equipment from brands like Rotobrush and Nikro. These systems physically scrub the inside of the duct walls rather than just blowing air through. Air-only cleaning without agitation doesn't remove caked-on dust and debris. The combination of rotary agitation and true HEPA capture is what separates a real professional cleaning from a glorified vacuum job.
Yes, and we recommend it for most Palo Alto homes. Many local homes have long dryer vent runs because the laundry area is in a central hallway or interior closet, which means lint accumulates faster and creates a fire risk. Clogged dryer vents also make dryers work harder, which drives up energy costs. We can add dryer vent cleaning to your duct cleaning appointment, and it's included in our flat-rate estimate if you request it up front.
Brands & Parts FAQs
Yes, in the same way the brand of tools matters to any serious tradesman. Professional systems like those from Rotobrush and Nikro are engineered for continuous commercial use and deliver the agitation power needed to actually dislodge debris from duct walls. We pair that with high-filtration HEPA collection to keep the dislodged particulate contained. Inferior equipment is one of the things hidden behind those discount prices we mentioned, and it's one of the reasons those jobs don't get the system truly clean.
A fresh filter is always a good idea after a cleaning. Your filter catches airborne particles before they enter the system, and a clean system with an old filter just works harder. We can install a quality replacement filter, including options from Honeywell and Aprilaire, during the same visit. Pleated filters with a higher MERV rating do a better job of keeping the freshly cleaned ducts cleaner longer, and we'll help you pick the right one for your system, especially if anyone in the house deals with allergies.
Licensing & Insurance FAQs
Absolutely. Every professional working under our name is required to hold the licensing and insurance their state requires for this type of work. We never send someone into your home who doesn't meet those standards. We're happy to provide proof of insurance before the job starts, and most Palo Alto homeowners ask for exactly that. We've been serving the Peninsula since 2016, and our local reputation is built on doing the job right and standing behind the work.

Emergency & Response FAQs
Air duct cleaning is a scheduled service, not an emergency repair. We plan appointments in advance so we can bring the right equipment and take the time to do the job thoroughly. If you have an urgent concern, like water in the ductwork after a leak or smoke damage after a kitchen fire, call us at (833) 620-7085 and we'll talk through your situation and get you on the schedule as soon as possible.
That depends on the time of year and our schedule. Our service hours are Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. We do not take appointments on Saturday. The best way to find out is to call (833) 620-7085, and the coordinator can let you know what's available for your Palo Alto neighborhood. We'll work with you to find a time that fits.

Warranty & Guarantees FAQs
We stand behind every cleaning with a straightforward satisfaction guarantee: if something isn't done to your standard, tell us and we'll make it right. What that means in practice is simple. You'll see before-and-after photos of your own ducts from inside the system, so you can see the work was actually done, not just told it was. If you're not satisfied, call us and we'll address it. That's the standard we've been working to since 2016.
This is the single most common question we get from Palo Alto homeowners, and it's a fair one. The answer is the before-and-after photos we take inside your actual ducts. We don't show stock images or photos from someone else's house. You'll see the inside of your own supply and return lines before and after cleaning. The difference is usually obvious, and that visual proof is part of every job we do.
Every three to five years for most homes. That said, homes with pets, allergy sufferers, or recent renovation work may want it more often. Wildfire season on the Peninsula also changes the math; after a particularly heavy smoke year, we see a spike in calls from homeowners in the foothills around Woodside and Portola Valley whose ducts picked up more ash. If you can't remember the last time yours were cleaned, it's probably time. Call (833) 620-7085 for a free estimate.
You can swipe visible dust from vent covers, but real duct cleaning is not a DIY job. The inside of ductwork is inaccessible without commercial equipment, and a household vacuum simply doesn't have the power or reach to remove built-up debris from the system. Half-cleaning the visible vents while the inside of the ducts stays dirty gives you a false sense of a job done. The professional equipment we use exists precisely because this kind of cleaning requires it. If you're seeing dust accumulation, give us a call instead of fighting it alone.
