Frequently Asked Questions - Air Duct Cleaning in Santa Clarita, CA
Straight answers to the questions Santa Clarita homeowners ask us most, from real costs to what actually happens during a cleaning. If you don't see your question here, call (661) 523-0295 and ask us directly.
Pricing & Cost FAQs
Air duct cleaning in Santa Clarita typically runs $350 to $650 for a full system, depending on home size and how many vents and returns need cleaning. A smaller condo in Valencia or Canyon Country might land near the low end, while a larger two-story home in Stevenson Ranch or Newhall with two HVAC systems can push toward the top. We give one flat price per system, in writing, before any work starts. No per-vent pricing, no surprise line items at the door. Call (661) 523-0295 for a free estimate specific to your home.
Lowball quotes usually come from companies that price per vent, then count vents aggressively once they're inside, or from crews that do a quick vacuum of visible registers and skip the main trunk lines entirely. The bait-and-switch has been a problem in this trade for years, and it's exactly why we give one flat price per system in writing before work begins. The price we quote is the price you pay. If a quote seems too low to include the actual ductwork, it probably is.
For most Santa Clarita homes, yes, especially given our dry, dusty climate and the Santa Ana winds that push fine particulate into every gap. Homes with pets, recent remodeling, or allergy sufferers benefit most. The value comes down to whether the work is real: the full trunk lines, supply and return plenums, and all registers should be cleaned and documented. A legitimate cleaning should leave visible before-and-after proof. If a company can't show you what they actually cleaned, you didn't get what you paid for.
Standard homeowners insurance does not cover routine air duct cleaning. It's considered maintenance, not a covered peril. There are exceptions: if ducts were contaminated by a covered event like fire smoke, a burst pipe, or major water damage, your insurer may pay for cleaning as part of the remediation. Check your policy or ask your agent. We're happy to provide documentation of the work if you're filing a claim.
Neither. We charge one flat price per system, agreed in writing before any work starts. Per-vent pricing is how the bait-and-switch happens in this industry: a low per-vent teaser, then a vent count that doubles once the truck is parked in your driveway. We don't play that game. You'll know your exact cost before we touch a single register.
Service & Process FAQs
We connect a high-powered vacuum to your duct system to create negative pressure, then agitate the interior walls of the ducts with rotating brushes and compressed air tools to break dust, pet dander, and debris loose so the vacuum pulls it out. Every supply and return register is cleaned, along with the main trunk lines and plenums. We finish by cleaning the registers and grilles. The full process takes 2 to 4 hours for a typical Santa Clarita home, and we document the before-and-after so you can see the difference.
Most single-system homes in Santa Clarita take 2 to 4 hours. Larger homes with two HVAC systems, or homes with extensive duct runs, can take longer. We'll give you a realistic window when you book, and we honor the Garrison Code: arrive inside the window we gave, do the job by the book, and leave your home clean when we're finished.
Every 3 to 5 years is a reasonable schedule for most Santa Clarita homes. Our dry climate and regular Santa Ana winds mean more dust and fine particulate settles into ductwork than in coastal areas. Homes with shedding pets, smokers, recent renovation work, or family members with allergies may want cleaning every 2 to 3 years. If you've never had your ducts cleaned and your home is more than 5 years old, it's worth having them inspected.
No, not when it's done properly. The vacuum system maintains negative pressure inside the ductwork the entire time, which means dust is pulled toward the collection unit, not pushed into your living space. We protect the area around each register and clean up thoroughly when the job is done. Leaving the site clean and squared away is part of the Garrison Code.
We do remove each register cover to clean it and to access the duct opening. Register covers collect a surprising amount of grime on the back side, and leaving them in place means leaving that grime. Removal is quick and doesn't damage drywall or flooring. It's the only way to reach the duct interior properly with agitation tools.
Not much. Clear a space around each register so we can reach it, which usually means moving furniture or boxes that sit directly over or against a vent. If your air handler is in a closet, clear a path to it. Keep pets in a room away from the work area. We handle everything else, from drop cloths to cleanup.
It can help by removing accumulated dust, pollen, pet dander, and other allergens from the air pathway of your home. What sits in your ducts gets recirculated every time the system runs. In a windy, dusty climate like Santa Clarita's, that buildup happens faster. Duct cleaning isn't a cure for allergies, but it reduces the load your air filter has to catch, and many customers notice less dust settling on furniture afterward.
Brands & Parts FAQs
We work with professional-grade negative-air and brush systems, including equipment from names like Rotobrush and Abatement Technologies. These are the machines built for full-system cleaning, not the shop-vac-and-a-drill setups that give this trade a bad reputation. The equipment matters because it determines whether debris is actually pulled from the full length of your trunk lines or just from the first foot of visible duct.
We clean the duct system and the accessible components. We'll point you toward quality filtration, including brands like Aprilaire that make whole-home media filters, but we don't sell or install filter systems as a core service. We'll show you what your system uses and what condition the current filter is in, and we're glad to recommend what works well in Santa Clarita's dust-heavy air.
A quality filter protects the work. After a professional cleaning, your ducts are as clean as they'll ever be, and a good filter keeps them that way longer. Homes in the Santa Clarita Valley deal with a lot of fine dust from the surrounding hills and the I-5 corridor, so a pleated filter with a higher MERV rating, or a whole-home option like Aprilaire, makes a real difference. Ask us during your estimate and we'll point you the right direction.
Licensing & Insurance FAQs
Every professional working under the Hollis name is required to hold the licenses and insurance their state requires. That's a network-wide standard, not a marketing line. You should ask any contractor you let into your home to show proof of both. A legitimate company won't flinch at that request.
The standard across every Hollis location requires that professionals meet the credential and insurance requirements for their trade and state. We know the crew you let in matters as much as the work they do. That's why the Garrison Code exists: a disciplined, by-the-book standard that every location agrees to follow.
You don't have to be present for the full cleaning, though we recommend being there for the initial walkthrough so we can confirm the scope and answer questions. If you need to leave partway through, let the crew know how to reach you. Many Santa Clarita homeowners use the time to run errands in Valencia or grab coffee in Newhall while we work.
Emergency & Response FAQs
Generally no. Duct cleaning is a scheduled maintenance service, not an emergency call. If you have an urgent issue like mold discovered during remediation or construction dust that's circulating through a newly completed renovation, call (661) 523-0295 and we'll fit you in as quickly as our schedule allows. We're open Monday through Friday from 7:00 AM to 7:00 PM and Sunday from 7:00 AM to 7:00 PM.
Yes, and in those cases the work matters more than a routine cleaning. Smoke residue coats duct interiors and keeps recirculating odor and particulates long after the visible damage is addressed. If you've had a kitchen fire, a nearby wildfire event like those the Santa Clarita Valley sees in dry seasons, or heavy smoke intrusion, duct cleaning should be part of your remediation plan. Your insurer may cover it as part of the claim. Call us for documentation and a written estimate.
Call (661) 523-0295 and we'll find the next available window that works for you. We serve the entire Santa Clarita Valley, including Valencia, Newhall, Canyon Country, Saugus, Stevenson Ranch, and Castaic. When we give you a window, we keep it. That's the first rule of the Garrison Code: show up inside the window we gave you.
Warranty & Guarantees FAQs
Every Hollis job is covered by The Garrison Standard, which includes a written guarantee on the work for a full year. If the work fails in that time, we come back and make it right at no charge. It's part of the same standard that requires the price in writing before work starts, the job done by the book, and the site left clean. This isn't a handshake deal; it's in writing.
You should see it. We document every job with before-and-after photos of your actual ductwork, not stock images. You'll see the inside of your own trunk lines and registers before we start and after we finish. That's the verification that matters most in this trade: proof of the condition inside your ductwork, in your home, taken during your appointment.
Call us. The Garrison Code exists for exactly this scenario: stand behind the work for a full year, and if it fails, make it right at no charge. Start with a phone call, tell us what you're seeing, and we'll work from there. You won't get a runaround, because the standard we work under doesn't allow one.
