Frequently Asked Questions

A truck-mounted or high-powered portable vacuum connects to your duct system to create negative pressure. Then we use agitation tools, often Rotobrush or Nikro equipment, to dislodge dust and debris from the duct walls. The vacuum captures everything as it loosens. After the ducts, we clean the supply and return registers, the blower motor and housing, the evaporator coil if accessible, and the plenum. A full system cleaning for a typical Dublin home takes two to four hours. You'll see before-and-after photos of your own ducts when we finish.

Most single-family homes in Dublin, Livermore, or Danville take between two and four hours. A larger home with two HVAC systems can take half a day. The time depends on how long the duct runs are, how much buildup is present, and how many registers need removal and cleaning. We schedule air duct cleaning as a proper appointment, not a rushed stop. Call (855) 356-4417 to book a time that works for your schedule.

Before-and-after photos are the single best proof, and we take them of your actual ducts, not stock photos. Ask any company to show you the inside of your ducts before they start and again when they finish. You can also check the registers yourself after the job: run a clean white cloth inside the opening and see if it picks up dust. With Rotobrush or Nikro agitation equipment, the duct walls should look visibly cleaner. A trustworthy company won't hesitate to show you the work. We also walk you through what we found in your system.

It removes the reservoir, not the trigger. Dublin's spring brings heavy pollen from the Tri-Valley oak and grass, and if your ducts contain months of accumulated dust, pet dander, and pollen, that material recirculates every time the system runs. Cleaning removes that accumulated load, which can reduce the volume of particulate in your indoor air. It does not stop new pollen from entering through open windows or on shoes and clothing. Pair duct cleaning with a quality filter, something like a Honeywell or Aprilaire high-MERV media filter, for the best result through allergy season.

After. Always after. Renovation dust from drywall sanding, flooring work, and cutting gets pulled into the return ducts while work is happening. If you clean before a remodel, you'll pay twice. Sacramento area drywall dust is extremely fine and travels everywhere, which is also a reason to seal off returns during any active work. Once the contractor is finished and the dust has settled, that's the right time to clean the entire system. Homeowners across Dublin, Camino Tassajara, and Blackhawk call us after kitchen and bathroom remodels for exactly this reason.

Every three to five years for most Dublin homes under normal conditions. You can stretch longer if you run a high-quality filtration system and have no pets. You should clean sooner if you have shedding pets, recent renovation work, a smoker in the home, or allergy sufferers. Homes near open space in Danville or Alamo collect more fine dust and pollen than you might expect. If you can't remember the last cleaning or you just bought the home from previous owners, assume the ducts need attention and have them inspected.

We ask that you clear easy access to each register before we arrive. That means moving small furniture and clearing items off floor vents. For larger pieces, we can work around them in most cases. Our equipment runs from outside or from the garage where possible, with hoses brought through a window or door. We wear shoe covers inside your home, lay down corner guards and drop cloths where hoses pass, and clean up thoroughly when the job is done. Your Dublin home should look exactly like we found it, minus the years of dust.

We use professional-grade agitation and collection equipment from manufacturers like Rotobrush and Nikro. These are powered brush and vacuum systems designed specifically for residential ductwork, not a shop vac with a long hose. The difference matters. Proper negative-pressure collection keeps dislodged dust from blowing into your living space. Agitation tools scrub the duct walls so the vacuum can capture what's stuck. The equipment is the same class used by professional duct cleaners across the country, and it's one of the reasons we can show you a real before-and-after.

We do recommend high-quality media filters from brands like Aprilaire and Honeywell, especially for Dublin homeowners concerned about indoor air quality or managing spring pollen. These filters fit into a cabinet at your air handler and provide substantially better filtration than a standard one-inch fiberglass filter. If your system currently runs a basic filter, upgrading the filter media makes the effects of a duct cleaning last longer. We can quote filter installation separately when we're at your home, with the same one-price-per-job policy.

We clean both. Most newer Dublin homes use flexible ductwork in the branch lines, while older homes in San Lorenzo, Cherryland, and Fairview are more likely to have rigid metal ducts. Flex duct requires a gentler agitation method because the inner liner can tear if too much force is applied. That's another reason experience matters, and why the right equipment for the duct type is important. We assess your system's composition during the estimate and adjust our process accordingly.

Every pro working under our name is required to hold the license and insurance their state requires. That means general liability coverage is in place before we step foot in your home, and our team carries the proper protections. You're welcome to ask us for current documentation when you book, and we'll provide it without hesitation. Air duct cleaning doesn't require a specialty contractor's license in California the way HVAC installation does, but we believe in meeting the same professional standard homeowners expect from any trade working inside their house.

Every technician we send into Dublin homes goes through a screening process as a condition of working under our name. We send people into your home while you're there, often while your kids are home from school, and we take that responsibility seriously. You should feel comfortable asking any contractor you hire what their screening policy is. It's a fair question and a professional company answers it directly.

If your home was built before the mid-1980s and has original ductwork with suspected asbestos-containing wrap or insulation, we recommend testing before any duct cleaning begins. We do not do asbestos abatement ourselves, and cleaning ducts with deteriorating asbestos wrap is not something any reputable duct cleaner should attempt. If testing comes back positive, you'll need a licensed abatement contractor first. Once the abatement is complete, we're happy to clean the replacement ductwork. Safety and legal compliance come before a sale, every time.

We handle post-event duct cleaning for Dublin and Tri-Valley homeowners as part of scheduled service. After a small kitchen fire or water intrusion, smoke particles and moisture can enter the duct system and should be addressed quickly. Call (855) 356-4417 and describe what happened, and we'll schedule the cleaning and help determine whether additional restoration work is needed beyond the duct system. Our hours are Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM, and we're closed on Saturdays.

You can reach us and schedule service Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. We're closed on Saturdays. A live coordinator answers the phone during those hours and connects you with the local Dublin team. We schedule appointments in a way that respects your time, so we'll agree on a window that works for you rather than making you wait around all day.

We schedule duct cleaning on Sundays and weekdays. We're closed on Saturdays. Sunday appointments tend to book quickly in Dublin because they're popular with working families, so call early in the week if you need a specific Sunday slot. Our Sunday hours are 7:00 AM to 7:00 PM, same as weekdays. Call (855) 356-4417 and the coordinator can find the next available opening that fits your schedule.

Duct cleaning is a scheduled job, not an emergency dispatch. Depending on the season and our current bookings in Dublin, Livermore, and surrounding areas, we can often get you on the calendar within a few days to two weeks. Spring tends to be the busiest season across the East Bay. When you call (855) 356-4417, we'll give you the next honest availability. If your situation is urgent, like after a fire or water event, tell the coordinator and we'll do our best to accommodate you sooner.

If you can see dust still sitting in your ducts after we leave, that's a job not done. We stand behind the work. Our commitment is simple: if you're not satisfied with the results, contact us and we'll make it right. The before-and-after photos we take create a clear record of what your ducts looked like before and what they look like when we're finished. Call (855) 356-4417 to book, and we'll go over the guarantee details with you before any work starts.

We back our workmanship with a customer satisfaction commitment. If an issue arises with the cleaning itself, call us and we'll address it promptly. Bear in mind that ducts begin collecting new dust from day one, because your home generates dust, and no company can honestly promise ducts will stay clean for a set number of years. What we promise is that the cleaning is done thoroughly, with the right equipment, by people who take the work seriously, and we stand behind that.

If we cause damage, we fix it. Duct cleaning done with appropriate equipment and trained technicians is low-risk for your system. The most common concern is flex duct tearing, which is why we adjust our method based on the material your ducts are made from. Before we start, we do a visual check of accessible ductwork and note any pre-existing damage so there's no question about what was already there. The protections we carry are there for the unexpected, and we've built our Dublin reputation on being accountable when things go sideways, not on dodging responsibility.

Yes. After we finish, we provide before-and-after photos of your ducts along with a summary of what we found and what we did. If we see issues during the cleaning, like moisture staining, mold-like growth, pest evidence, or damaged duct runs, we'll flag those for you with photos. That report is yours to keep. For Dublin homeowners selling a home, documentation that the ducts were professionally cleaned can be a useful thing to have at inspection time, and we're happy to provide it.
