Why Dallas Homeowners Choose Trane Air Duct Cleaning
Air Duct Cleaning for Trane systems in Dallas costs between $450 and $900 for a complete system, depending on home size, the number of returns, and how long it’s been since the last cleaning. We are an independent Trane service provider, not a Trane authorized dealer, which means we answer to you and the condition of your ductwork, not a corporate parts quota. Our technicians work on Trane systems across Dallas daily, from 1980s XL series air handlers in Lake Highlands to current RunTru and Ameristar installations in new construction, giving us a field-tested read on how these units collect and hold debris in this specific climate. Roy Castellanos, who leads our crew, trained at Los Angeles Trade-Technical College and has spent years running Trane-specific inspections in homes from Oak Cliff to the Design District.

Why Trust Hollis Air Duct Dallas for Your Trane Air Duct Cleaning?
Trane builds solid equipment, but the ductwork attached to it is where the real maintenance story lives in Dallas. Our technicians are familiar with the specific quirks of Trane XR, XL, RunTru, and Ameristar systems, including how their blower cabinets, coil orientations, and return plenums age in North Texas attics and crawl spaces. Roy Castellanos has worked around Trane equipment since he completed his HVAC training at Los Angeles Trade-Technical College, and his crew has serviced enough of these systems across Dallas and Richardson Trane service areas to know exactly where debris collects and where leaks form first.
We use OEM Trane filters and mastic rated for Trane duct systems when sealing is required. For flex duct repair in hot Dallas attics, we often recommend quality aftermarket cloth-backed tape and commercial-grade flex that hold up better than what many original installations used. We warranty our work with the 365-Day Done Right Promise, in writing, on every job. If a sealed joint fails within a year, we come back and fix it at no charge. That promise stands regardless of what brand of equipment you own.

Common Trane Air Duct Cleaning Problems We Fix in Dallas
Every brand has its patterns. Here are the five we see most often on Trane systems in Dallas homes:
- Evaporator coils clogged with pollen and cottonwood on XR and XL condensers. Dallas spring brings cottonwood that packs into outdoor condenser fins, while fine pollen gets pulled through the return and cakes the evaporator coil inside the air handler. On Trane XR and XL systems, a loaded coil forces the blower to work against higher static pressure, which shortens motor life and raises cooling bills through the hottest months.
- Flex duct degradation on RunTru and Ameristar installations. RunTru and Ameristar are Trane’s value lines, and many Dallas builders pair them with inexpensive flex duct that breaks down faster in attic heat. After ten or twelve summers at 140 degrees in an attic, the inner liner separates from the insulation, airflow drops, and conditioned air leaks into the attic. We replace the failed runs with commercial-grade flex rather than patching a duct that will fail again.
- Blower wheel dust buildup on XL systems causing vibration and noise. Trane XL air handlers have blower wheel blades with a slight pitch that catches fine dust over time, especially in homes with pets or carpet. When the wheel gets out of balance, you hear it as a rumble or a hum that changes with airflow. Cleaning the wheel and housing in place is often enough to quiet it down, but if the buildup has already pitted the blades, replacement is the honest fix.
- Return duct leaks at sheet metal junctions on older Trane XL air handlers. Houses built in the 1960s and 70s in neighborhoods like Casa View and Lake Highlands often have galvanized return chases that were sealed with tape that dried out decades ago. Those leaks pull attic insulation fibers, dust, and hot air into the return side of the system. We seal the junctions with mastic, which stays flexible through Dallas heat and cold cycles longer than any tape product.
- Disconnected or crushed ducts in pier-and-beam homes. Many older Dallas homes in East Dallas and Oak Cliff sit on pier-and-beam foundations with ductwork running under the house. When a flex duct separates from a boot or a metal trunk line comes apart at a seam, the system pulls dirt, rodent droppings, and crawl space humidity into the air you breathe. We inspect from the return plenum all the way to the final register so nothing gets missed.
Trane Parts & Our Repair-vs-Replace Approach
When a Trane component can be cleaned and returned to service, we clean it. When it’s too far gone, we say so instead of cleaning around it. That distinction matters, because a badly corroded blower wheel or a coil with fins that have rotted from years of humidity will not be fixed by a cleaning, and pretending otherwise wastes your money.
For seals, we use mastic rated for Trane duct systems. For filters, we stock the OEM sizes Trane air handlers require, including the odd-width return grill sizes on older XL and XR units. For flex duct, we carry commercial-grade replacement runs with a higher R-value than what many builder installations used. We keep these on the trucks so a diagnosis on Monday is a repair on Monday, not a parts order that takes a week. If a repair does not hold, the 365-Day Done Right Promise brings us back free. Call (361) 309-6223 for an honest assessment of what you actually need.
Our Trane Service Process – Step by Step
- 1
Inspection. We check the furnace or air handler cabinet, the evaporator coil, the blower wheel, the return plenum, and as much of the supply and return ducting as is accessible. On Trane XL and XR systems we also check the drain pan and condensate line, because a clogged drain from coil debris is a common Dallas failure.
- 2
Written diagnosis and fixed price. Roy Castellanos reviews the findings with you before any work starts. The price is written down. It does not move once the work begins.
- 3
Cleaning and repair. We run negative-air extraction at the air handler while the rotary brush works through the main trunk and branch lines. Coils get a no-rinse cleaner approved for Trane aluminum fin coils. Separated flex runs get mastic-sealed or replaced in full.
- 4
System test. We measure static pressure and airflow at the return and a sample of supply registers, then run the system through a full cycle to verify the blower is moving air as designed. On variable-speed Trane blowers we check all fan speed profiles.
- 5
Warranty documentation. You get the written price, the written scope of work, and the 365-Day Done Right Promise in hand before we leave.

AfterTrane Products We Service & Install in Dallas
We service and clean the duct systems attached to Trane XR series condensers and air handlers, XL series units including the XL16i and XL20i, RunTru packaged and split systems, and Ameristar residential installations in Trane in Garland and surrounding areas. Our focus areas on these systems are evaporator coil cleaning, flex duct repair, and duct sealing, which is where Dallas humidity and attic heat do the most damage. We also install replacement flex duct and seal supply and return plenums on all Trane-compatible system configurations.
One recent job in North Dallas stands out. Our tech opened a Trane XR16 air handler and found the evaporator coil so loaded with pet hair and dust that the blower was pulling only 60% of design airflow. We deep-cleaned the coil with an approved no-rinse cleaner and sealed a separated flex duct in the attic with mastic, bringing static pressure back to spec without replacing the unit. That is the kind of outcome a proper Trane inspection should deliver.
We Also Service These Brands
While Trane systems are a large share of what we see in Dallas, we also work on Lennox and Carrier equipment regularly. The ductwork, cleaning methods, and sealing standards are the same. The brand on the air handler does not change how we price the job, which is written down before work starts.
FAQs – Trane Air Duct Cleaning Service in Dallas
No. The cleaning process is the same regardless of brand. What differs is where we focus the inspection. On Trane XR and XL systems we pay extra attention to the evaporator coil and blower wheel, because those are the components where Dallas pollen and fine dust build up fastest on these models.
It is common but not normal. A musty smell on startup usually means mold or mildew is growing on the evaporator coil or inside the air handler cabinet, fed by condensation and Dallas humidity that never fully dries out during our long cooling seasons. Cleaning the coil and treating the condensate pan and drain line typically removes the odor at the source. If the smell persists after cleaning, we will tell you what else needs attention.
If your evaporator coil or blower wheel is loaded with dust, yes, cleaning can measurably improve airflow and cooling performance. We have seen Trane XL air handlers pulling 40% less air than design spec due to coil buildup alone. If your ducts are clean but the system still struggles, the problem is elsewhere, and we’ll say so instead of selling you a cleaning you do not need.
Yes. We schedule with the tenant to make sure pets are secured and access to the air handler is clear. The process runs the same as in an owner-occupied home, and the written price and 365-Day Done Right Promise apply to rental property work the same way they do to any other job. Call (361) 309-6223 to schedule an estimate.
Yes. We do not open the blower motor or alter any electrical settings. Negative-air extraction and rotary brushing work on the duct system, not the motor itself. Before we start, we confirm the blower is off and locked out, and after cleaning we run all fan speed profiles to confirm normal operation. Variable-speed Trane blowers are more sensitive to airflow restriction than single-speed motors, which makes regular coil cleaning more important, not less.
Most complete system cleanings for Dallas homes run between $450 and $900. Smaller homes with a single return and short duct runs sit at the lower end. Larger two-story homes with multiple returns, long flex runs in the attic, or a badly loaded evaporator coil run higher. The price is written before any work starts and does not move at the door. Call (361) 309-6223 for a free estimate specific to your home.
