AfterFull System Cleaning in Dallas, TX
Full system air duct cleaning in Dallas typically costs between $450 and $900 for a single-family home up to 2,500 square feet, and most jobs are completed in 4 to 7 hours. We clean every component of your forced-air system: supply ducts, return ducts, the blower motor, evaporator coil, drain pan, registers, and grilles. Hollis Air Duct Dallas has run this service since 2004, and the price you get on the phone is the price on the invoice. Call (361) 309-6223 for a written quote before any work begins.
Full system cleaning goes beyond the basic duct sweep that cheaper outfits advertise. A complete job means pulling the air handler open, cleaning the coil with proper solvents, washing the blower wheel, and running a negative-air machine the entire time. That is the difference between cleaning the pipes and cleaning the whole system. If you want to understand the full scope, see our Air Duct Cleaning in Dallas page. We cover the trade in plain terms there.
Key Takeaways
- Full system cleaning covers ducts, blower, coil, drain pan, registers, and grilles in one visit.
- Expect to pay $450 – $900 for a typical Dallas single-family home; larger homes with multiple systems run higher.
- We arrive with Nikro negative-air machines and Rotobrush rotary brush systems, not hardware-store shop vacs.
- Every job gets a written price first, and the 365-Day Done Right Promise covers the work for a full year in writing.
When You Need Full System Cleaning
Dallas runs air conditioning eight months a year. That means your ducts and air handler work harder and collect more than systems in cooler climates, making Residential Duct Cleaning essential. Here is when a full system cleaning makes sense:
- You have not cleaned the ducts since you bought the house. In older Dallas neighborhoods like Lake Highlands or Casa View, ducts often carry 15 to 30 years of settled dust, pet dander, and sheetrock dust from renovations.
- The dust comes back days after you wipe the furniture. That points to the system recirculating what is already inside the ducts, not dust entering from outside.
- Someone in the house deals with allergies or asthma. Full system cleaning removes the settled particulate that a basic vent vacuum leaves behind, especially around the evaporator coil where mold grows in Dallas humidity.
- You smell something stale or musty only when the AC runs. That smell usually lives on the coil or inside the drain pan. A duct-only cleaning never touches those parts.
- Your air handler is in the attic. In Dallas attics, temperatures hit 140 degrees in summer. Heat breaks down dust and insulation particles, and those circulate every time the blower runs.
- A renovation just finished. Sheetrock dust, sawdust, and paint overspray get pulled into return ducts during construction. In neighborhoods like Preston Hollow and Bishop Arts, remodels happen constantly, and that dust settles inside the system.
Our Full System Cleaning Process
Every Hollis Air Duct Dallas full system cleaning follows the same steps, in the same order, with the same written standard. That is the Garrison Standard, and it is the reason we put the price in writing before we touch the system.
- Walkthrough and written quote. We inspect the system, note the number of registers, system size, access points, and any visible mold or damage. Then we hand you the written price. That number does not change after we start.
- System isolation and negative-air setup. We connect a Nikro negative-air machine to the main trunk line. The machine pulls the house air through the system and captures it in HEPA filtration while we work. This keeps loosened dust from blowing into your living room in the middle of the job.
- Supply and return duct cleaning. A Rotobrush rotary brush system travels through each supply and return run, mechanically agitating the interior walls while the negative-air machine captures what comes loose. We cut access points as needed and seal them after.
- Air handler cleaning. We pull the blower motor, wash the blower wheel, clean the evaporator coil with the correct solvent, and clear the drain pan and condensate line. This is the part a duct-only cleaning never does, and it matters most for airflow and odor.
- Registers, grilles, and boots. Every register and grille gets removed, wiped, and reinstalled. We vacuum the boot where the duct meets the register.
- Final inspection and site cleanup. We walk you through what was done, show before-and-after photos of the coil and blower if you want to see them, and leave the site clean. Our technicians are background-checked and uniformed, and the work is covered by the 365-Day Done Right Promise.
Full System Cleaning Pricing in Dallas
Full system air duct cleaning in Dallas runs between $450 and $900 for most single-family homes. The price depends on the number of systems, square footage, access difficulty, and the condition of the coil and blower. Here is how the pricing typically breaks down:
| Home Size | Typical Dallas Price Range | Time on Site |
|---|---|---|
| Up to 1,500 sq ft, 1 system | $400 – $600 | 4 – 5 hours |
| 1,500 – 2,500 sq ft, 1 system | $500 – $750 | 5 – 6 hours |
| 2,500 – 3,500 sq ft, 2 systems | $700 – $950 | 6 – 8 hours |
| 3,500+ sq ft, 2+ systems | $900 – $1,400 | 7 – 9 hours |
What changes the price:
- Number of systems. A two-story Dallas home with a downstairs unit and an attic unit is two jobs from our side. The price reflects that.
- Coil condition. A heavily fouled evaporator coil takes longer to clean and may require more aggressive, EPA-registered cleaning agents. We quote that after inspection, and the quoted number stays put.
- Mold or moisture remediation. If we find active mold growth on the coil or in the ducts, we will recommend a separate treatment. We do not fold surprise line items into the final bill. Ever.
- Attic access. Tight attics, low rafter clearances, and difficult access points add hours. We tell you before we start, not after.
We give free estimates. A call takes about ten minutes, and you get a written range before we set a date. Call (361) 309-6223 and we will send a background-checked technician to your home, not a salesperson.
Full System Cleaning vs. Regular Duct Cleaning
If you have seen $99 duct cleaning ads around Dallas, you already know something does not add up. Here is the straight version. A basic duct cleaning runs a vacuum through a few accessible return drops and calls it done. It might take 90 minutes. A full system cleaning pulls the blower, opens the air handler, cleans the coil and drain pan, and runs a negative-air machine through every supply and return run in the house. One method costs $99 and changes the air inside the ducts. The other costs $450 to $900 and changes the air inside your home. Both are legitimate services. Only one is what we offer under the Hollis name. Our Air Duct Cleaning in Dallas page explains the difference in more detail.
Why We Use the Equipment We Use
You will see us carry Nikro negative-air machines and Rotobrush rotary brush systems onto the truck. Those are the same brands commercial building crews use in hospitals and Class A office towers in downtown Dallas. The negative-air machine is the critical piece: it keeps the house under constant suction so dust never migrates into your kitchen or bedrooms during the job. We also replace and recommend filtration upgrades from Honeywell, Aprilaire, and Abatement Technologies when the system calls for it. We are not running hardware-store gear, and we do not need to tell you that twice. You will see it at the curb.
Why Dallas Homes Need This More Than Most
Dallas is a particular case for air duct maintenance. The city runs on forced-air cooling from March through November, and the humidity on this side of the Texas line means the evaporator coil is almost always moist. That is a recipe for dust adhesion and mold growth on the coil fins. Add in the clay soil and construction dust that drifts through neighborhoods like East Dallas and Oak Cliff, and the inside of a Dallas duct system becomes a long, dark collector.
We see it on a regular basis: a homeowner in Richardson or Garland has the ducts vacuumed, the dust comes back in two weeks, and the problem was never the ducts. The problem was a coil caked with damp, compacted dirt that a duct-only crew never opened the air handler to see. Full system cleaning fixes the source, not just the symptom.

FAQs – Full System Cleaning
How much does full system air duct cleaning cost in Dallas?

The price is set in writing before we start and does not change. Call (361) 309-6223 for a free, written estimate for your home.
How long does a full system cleaning take?
A full system cleaning takes 4 to 7 hours for a typical Dallas single-family home, depending on the number of systems and the condition of the coil and blower. We arrive inside the quoted window and complete the job the same day.
Is full system cleaning worth it compared to regular duct cleaning?
Full system cleaning is worth the difference if you have allergies, a musty odor when the AC runs, or dust that returns quickly after cleaning. It costs more than a Air Duct Cleaning services duct-only job because it includes the blower, evaporator coil, drain pan, and air handler interior, which a $99 duct special never touches. For most Dallas homes with 10-plus-year-old systems, full system cleaning is the only meaningful option. Call (361) 309-6223 and we will walk you through what your system actually needs.
Will full system cleaning help with dust in my Dallas home?
Yes, full system cleaning reduces recurring dust by removing the settled particulate inside the ducts, blower, and coil that recirculates every time the system runs. In Dallas specifically, we find the biggest dust contributor is often a dirty evaporator coil, not the ducts themselves. Our process cleans the coil as part of the job, which is what stops the dust from coming back. Call (361) 309-6223 for an inspection and written quote.
