Frequently Asked Questions - Air Duct Cleaning in Dallas, TX
Straight answers to the questions Dallas homeowners ask us most about air duct cleaning, pricing, and what actually happens during the job. If you don't see your question here, call (361) 309-6223 and ask us directly.
Pricing & Cost FAQs
Air duct cleaning for a typical Dallas home runs $450 to $900 for a complete system, depending on square footage, the number of returns, and how long it's been since the last cleaning. Homes in older neighborhoods like Lake Highlands or Oak Lawn often run toward the higher end because decades-old ductwork holds more buildup. Homes in newer developments like Murphy or Heath tend to land in the middle of that range. You get a written price before any work starts, and that price doesn't move at the door. Call (361) 309-6223 for a free estimate based on your home's actual system.
Low quotes usually mean per-vent pricing that multiplies fast once the crew arrives, or a teaser rate that only covers a partial cleaning. A $99 whole-house offer in Dallas is almost never a whole house by the time the van shows up. We quote one flat price per system, in writing, before any work begins. That price covers all supply and return ducts, the blower, the coil, and the plenums. If a quote seems too good to be true for a four-bedroom home in Richardson, it probably is. Get the full-system number in writing and compare honestly.
Per system. One flat price for the entire duct system, agreed in writing before we start. Per-vent pricing is where bait-and-switch quotes come from in this trade, and we won't do it. A three-bedroom house in Garland and a five-bedroom house in Highland Park will have different prices because the systems are different sizes, but you'll know your number before the equipment comes off the truck. No multipliers, no surprise line items, no "that return costs extra" conversation after the fact.
Three things move the price: the size of the system, the age of the ducts, and whether there's contamination beyond normal dust. A single-story ranch in DeSoto with eight vents cleans faster than a two-story in Sachse with two returns and twenty runs. Older flex duct in 1980s homes tends to hold more debris and takes longer to do properly. If a dryer vent or the AC coil is included, that's part of the written quote. We'll walk the system with you and explain what we're seeing before you commit to a dollar.
For most Dallas homes, yes, if it's done by the book. North Texas runs the AC hard from May through September, which means your ducts are actively circulating air through whatever has settled in them. A cleaning that removes the accumulated dust, pet hair, and construction debris from renovation projects gives your system a cleaner start each season. It's not a miracle cure for allergies and we won't sell it as one. It's maintenance, like cleaning the gutters or flushing the water heater. Do it when the ducts are dirty, and not before.
Service & Process FAQs
A proper cleaning covers every supply and return duct, the main trunk lines, the branch runs, the plenums, the blower compartment, and the AC coil if accessible. We use negative-pressure equipment and agitation tools to break debris loose and pull it out of the system rather than pushing it into your living room. The job includes before-and-after photos of your ducts so you can see what was actually removed. Expect the crew to protect your floors, work clean, and leave the site the way they found it.
Most Dallas homes take four to six hours from arrival to final walkthrough. A smaller single-story in Red Oak can go faster; a large two-story in Highland Park with a complicated duct layout can run longer. The time goes into doing the job right: protecting the floors, setting up the negative air machine, cleaning each run individually, and then putting everything back squared away. We'd rather take the full time and show you photos of clean ducts than rush through and leave half the system untouched.
You should be home for the first few minutes to walk the system with the crew and confirm the written price, and for the final walkthrough to review the before-and-after photos. You don't need to watch the whole job, but being on-site at the start and finish is the best way to know the work was actually done. If you work from home in Lake Highlands or commute from Rowlett, we'll work around your schedule within our posted service hours.
Yes, and it's a smart add-on for Dallas homes. Dryer vents in this climate collect lint fast, and a clogged dryer vent is a fire risk that has nothing to do with how clean your laundry room is. We can include the dryer vent in your written quote and clean it during the same visit. If you're already having the duct system cleaned, adding the dryer vent costs less than scheduling it separately later. Ask about it when you call (361) 309-6223.
Not when it's done by someone who knows what they're doing. The risk comes from aggressive tools used on old or improperly installed flex duct. In Dallas homes with original 1990s flex runs, we adjust our approach to be gentler. Roy Castellanos and the local team inspect the condition of the ductwork before we begin and flag anything that looks fragile. If a section of duct is already failing, we'll show you and talk through options rather than making it worse and walking away.
Every three to five years for most Dallas homes, sooner if you've had major renovation work, a pest problem, or a water intrusion. Homes with multiple pets in Garland or Sachse often benefit from a cleaning every three years. Newer homes in Heath or Murphy that are tight and well-filtered can often go five years or more. The honest answer is that the ducts themselves will tell you: pull a vent cover, look inside with a flashlight, and if you see matted dust or debris, it's time. Don't clean on a schedule someone else set for you.
Brands & Parts FAQs
We run professional-grade negative air machines with HEPA filtration and pneumatic agitation tools designed for residential duct systems. The equipment brands we work with depend on the truck and the job, but you'll see names like Nikro and Abatement Technologies on our rigs. These aren't the portable units you rent at a hardware store. They're built for this trade, maintained between jobs, and paired with the right brush or air whip for the duct material we're cleaning.
We can recommend a filtration strategy based on what we find in your system, but our job is cleaning the ducts, not retailing filters. If your home would benefit from a high-quality media filter or a different approach, we'll tell you honestly and you can buy what you need anywhere. We work with homes that have Honeywell and Aprilaire filtration systems regularly, and we'll clean around them properly without damaging the housing or the filter rack.
Yes. Homes in Dallas with Aprilaire or Honeywell whole-home purifiers need the same duct cleaning as any other home, and the purifier doesn't make the job harder. We're careful around the purification equipment and won't disturb the wiring or the mounting. If the purifier has its own maintenance needs, we'll point you to the manufacturer's guidance rather than pretend it's part of the duct cleaning job.
Yes, the coil and blower compartment are part of a complete system cleaning. Dust that bypasses your filter settles on the blower wheel and the evaporator coil, and cleaning the ducts without addressing those components leaves the system half done. In Dallas, where the AC runs nonstop for months, a dirty blower works harder and moves less air. We'll include the coil and blower in your written quote and show you photos when we're finished.
Licensing & Insurance FAQs
Every crew working under the Hollis Air Duct Cleaning name is required to hold the license and insurance their state requires for residential HVAC and duct work. That's a network standard, not a marketing claim. The Dallas location is independently owned and operated, and the local team led by Roy Castellanos follows the same standard. You're welcome to ask for proof of insurance before we start, and a legitimate operation will never hesitate to show it.
Every pro working under our name is required to meet the screening standards set by Hollis Air Duct Cleaning before they enter a customer's home. We take that seriously because we're sending people into occupied houses in Dallas, Garland, Richardson, and everywhere else we serve. The people on the crew are local, they're professional, and they know the work. If you want to know more about our screening standards, call (361) 309-6223 and ask.
Hollis Air Duct Cleaning is part of the Garrison Partners family of home service brands. The Dallas location is independently owned and operated by a local team that agreed to work to The Garrison Standard. That means the same pricing discipline, the same written guarantee, and the same approach to clean, squared-away work whether you call us here or a sibling brand in another city. We live in the Dallas area and we serve the Dallas area.
Emergency & Response FAQs
Our Dallas 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 are not a 24-hour operation, and we won't pretend to be. For a genuinely urgent situation like a water intrusion in your ductwork, call (361) 309-6223 and we'll do our best to schedule you as soon as possible within our posted hours. Most duct cleaning work in Dallas is scheduled, not dispatched, and we'd rather give you a real arrival window than a false emergency promise.
First, don't run the system if you can avoid it. Visible mold in the ductwork should be assessed by a professional who can determine whether it's surface growth or something deeper. Duct cleaning removes the surface contamination, but if the mold is inside the duct material itself or there's an underlying moisture problem, the fix may involve replacement. In Dallas humidity, moisture in ducts is a real issue, and we'll be honest about what cleaning can and cannot do. Call (361) 309-6223 to talk through what you're seeing.
Yes, our service area includes Dallas proper and the surrounding communities: Garland, Richardson, Rowlett, Heath, DeSoto, Red Oak, Highland Park, Sachse, Oak Lawn, Murphy, and Lake Highlands. If you're in a neighborhood we don't regularly serve, call anyway. Sometimes a job just outside the usual radius is still a fit, and if it isn't, we'll tell you straight rather than waste your time.
Warranty & Guarantees FAQs
Every job comes with a written guarantee: if the work fails within one year, we come back and make it right at no charge. That's The Garrison Standard, and it applies to every Hollis Air Duct Cleaning location. The guarantee covers the quality of the cleaning itself, not normal re-accumulation of dust from daily living. If debris is still circulating through your system weeks after a cleaning and it should have been removed, that's a warranty issue and we'll handle it.
You'll see before-and-after photos of your own ducts, taken during the job. Not stock photos, not a diagram, actual pictures from inside your system in your home. We show you the access points before we close them up and walk you through what changed. That plus the written guarantee is how you know. If you want to inspect the ducts yourself afterward, you should, and we'll show you exactly where to look.
Then you call us and we address it. The guarantee is in writing for a full year, and if something was missed or the job wasn't done to standard, we come back and make it right at no charge. That's the whole point of putting the promise on paper. We'd rather spend an afternoon redoing a section of ductwork than have a Dallas homeowner wonder if they got what they paid for. One call to (361) 309-6223 and it gets handled.
Yes. Estimates are free, and the number we quote is the number you pay. No per-vent multipliers, no surprise charges at the door, and no pressure to sign before you've had time to think. Tell us about your home over the phone or book an in-person assessment, and we'll give you a written price based on your actual system. Call (361) 309-6223 and we'll get you a number.
