Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Air Duct Cleaning Across Keller
Air duct cleaning in Keller typically runs $350 – $650 for a single-system home and $900 – $1,800 for homes with two or three independent HVAC systems, with most jobs completed in one scheduled day. We’re the Air Duct Cleaning team at Hollis, and our crews serve Keller from our Dallas-Fort Worth dispatch office. We know the area: the large-lot subdivisions off Rufe Snow Drive, the gated communities near Bear Creek Parkway, and the older builds around Keller Smithfield Road where flex ductwork in unconditioned attics has been baking since the 1990s. Call (361) 326-5060 for a free estimate. We’ll price it per system, in writing, before any work starts.
Why Hollis Air Duct Cleaning Is Keller’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Keller on showing up uniformed, pricing in writing, and leaving the site clean. That’s The Garrison Standard, and it’s how every Hollis crew operates.
Our technicians are background-checked and accountable. You know who’s walking into your home before they arrive. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues.
Every job carries our 365-Day Done Right Promise: if the work fails within a year, we return and make it right at no charge, including a free second visit. That’s written down on every invoice, not implied.
We understand Keller’s housing stock. The late-1980s-through-2000s builds with multiple zones, the undersized original ductwork, the kinked flex runs in 140-degree attics. Local knowledge means we don’t quote blind.
HVAC Duct Cleaning in Keller
HVAC Duct Cleaning in Keller means source removal from the complete supply and return network tied to each air handler, not just vacuuming around the vents you can see. For a typical Keller home with one system, expect $350 – $650. Homes with two or three independent systems run $900 – $1,800 total, priced per system so you know exactly what each network costs before we start.
Keller’s extreme DFW summer heat means HVAC systems run near-continuously from May through September, driving heavy dust and allergen accumulation in ductwork. The dense post-1990 suburban subdivisions with tight construction trap those allergens inside. Many homes also have flex duct runs in unconditioned attics that degrade or kink, making duct cleaning a seasonal necessity that keeps systems efficient during peak cooling season.
Multi-System Homes
Many Keller properties have two or three separate HVAC zones. We price and document each system independently. You get a per-system report with before-and-after photos, not a vague “whole house” invoice.
Attic Flex Run Attention
Long flex duct buried in unconditioned attic space is where most Keller debris hides. We use negative-air machines and rotary brush agitation to reach those runs, then camera-inspect to confirm the work.
Vent Cleaning in Keller
Vent Cleaning in Keller covers the supply and return registers, grilles, and boot connections visible in your living spaces, plus the first few feet of ductwork behind each opening. This service typically runs $150 – $300 as a standalone job, or it’s included in a full HVAC duct cleaning package. Keller homeowners often request vent cleaning when they notice visible dust buildup, musty odors from registers, or reduced airflow in specific rooms.
Standalone vent cleaning makes sense between full system cleanings, especially in high-traffic areas or after renovation work. It’s also a good entry point if you’re unsure whether your full duct network needs service.
Register and Boot Detail
We remove each register, clean the boot and nearby duct section, and treat for microbial growth if needed. No surface wiping and calling it done.
Airflow Testing
After vent cleaning, we check airflow at each register. In Keller’s multi-system homes, this often reveals duct leaks or kinks upstream that need separate attention.
Trusted Brands We Service in Keller
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation inside duct walls, Nikro negative-air machines for controlled debris extraction, and filtration products from Honeywell and Guardsman. We stock common replacement components locally for Keller customers, so if camera inspection reveals a disconnected boot or damaged flex section, we can often address it during the same scheduled visit rather than booking a return trip. The tools are professional-grade, not hardware-store gear, and our technicians explain what each piece does and why it matters for your specific system before starting work.
Common Air Duct Cleaning Problems We See in Keller Homes
- Contractors quote one “whole house” price for homes with two or three independent systems. They clean the one air handler they can reach and leave the other supply and return networks untouched. We price per system, and we clean every network we quote.
- Crews skip real source removal in long attic flex runs. Kinked or torn sections keep dumping attic dust back past your MERV-rated filter and into your living space. We camera-inspect those runs and document what we found.
- No documentation for work the homeowner cannot see. When you upgrade to a higher-efficiency system, you can’t prove whether the original undersized or leaky ductwork was ever cleaned or sealed. We provide before-and-after photos and a written per-system report.
- Original 10 SEER ductwork never upsized for new high-efficiency equipment. In many Keller neighborhoods, homes got new condensers but kept leaky, undersized ducts. Cleaning and sealing are critical to realize the efficiency you paid for.

FAQs About Air Duct Cleaning in Keller
You pay per system, and we quote each one separately before starting. A typical three-system Keller home runs $900 – $1,800 total. Each system gets its own negative-air setup, agitation cleaning, and before-and-after documentation. Call (361) 326-5060 for an exact quote.
We camera-inspect before and after, and you get the photos in your per-system report. On a two-story home off Rufe Snow Drive in Keller, we found three separate systems, each with its own air handler, and one upstairs trunk line in the unconditioned attic with a kinked flex run feeding two bedrooms that never cooled properly. We set up negative pressure and HEPA filtration at each air handler, used agitation tools and a rotary brush through the supply and return ducts, pulled the debris past the blower motor compartments, and camera-inspected the runs before and after. The homeowner got a per-system report with before-and-after photos for all three systems, and the kinked run was flagged for sealing so the newer high-efficiency condenser could actually do its job.
Your original ductwork was likely never upsized for the new equipment. Many Keller homes built with 10 SEER systems got upgraded condensers but kept undersized or leaky attic flex runs. Cleaning reveals the condition; sealing fixes the performance. Call (361) 326-5060 and we’ll camera-inspect to confirm.
Every three to five years for most Keller homes, or sooner if you’ve renovated, replaced your HVAC, or notice reduced airflow or musty odors. The near-continuous cooling season from May through September accelerates dust and allergen buildup, especially in tight post-1990 construction. Call (361) 326-5060 to schedule.
We do both. Dryer vent cleaning runs $120 – $200 and can be scheduled with your duct cleaning or as a standalone service. Many Keller homeowners bundle them. Call (361) 326-5060 to book.
