Carrier Air Duct Cleaning in Houston, TX | Hollis Air Duct Houston
Air Duct Cleaning in Houston for Carrier systems typically runs $450 – $950 for a full system, depending on house size, number of returns, and how much the ducts have collected over the years. We’re an independent Carrier service provider, not a factory-authorized shop, which means we answer to you, not to a corporate service quota. If you own a Carrier Infinity, Performance, or Comfort system in Houston, call (713) 936-5800 and we’ll give you a written price before anything gets touched.
Roy Castellanos runs our Houston crew. He learned his trade at Los Angeles Trade-Technical College and has spent well over a decade working Houston homes, including slab-ducted ranch houses in Meyerland that haven’t seen a duct brush since they were built. His team knows Carrier duct layouts the way a mechanic knows a specific engine. We offer full Carrier sales & service support, from coil cleaning to complete duct system restoration, across our Houston service area.
Why Houston Residents Choose Us for Carrier Service
Carrier builds good equipment. Houston destroys it faster than most cities. The humidity, the pollen, the post-Harvey silt nobody talks about. We’ve spent years tracing Carrier duct layouts in this city, from slab-ducted ranch systems in Meyerland to the high-velocity flex runs in Cinco Ranch. We know exactly where Carrier systems trap construction dust and Gulf Coast moisture.
Here’s what that looks like on a job. We arrive in uniform, background-checked, and we write the price down before we open a single access panel. You get a fixed number. If the work fails within 365 days, we come back and make it right, no charge, in writing. That’s the Garrison Standard. Roy doesn’t do upsells at the door and neither does anyone on his crew. When we clean Carrier ducts in Houston, we use Rotobrush rotary brush systems and Nikro negative-air machines, the same class of equipment commercial crews run, not a hardware-store shop vac.
We stock OEM Carrier replacement parts for blower wheels, control boards, and coils when a component is under warranty or critical to airflow. For duct sealing, we use commercial-grade mastic and closed-cell wrap that exceeds builder spec. That matters in Houston because builder-grade flex duct connections fail fast in humid attics.

Common Carrier Air Duct Cleaning Problems We Solve in Houston
- ECM blower motor dust in supply ducts. Carrier air handlers with ECM blower motors shed fine dust from bearing wear over time. That dust settles in the supply ducts before the filter ever sees it. We see this constantly in Houston, where systems run from March through October and the blower rarely stops. The fix is a full supply-side cleaning, not just a filter change.
- Microbial growth on Infinity and Performance coils. Houston’s constant humidity means condensation never fully dries, even when the drain pan is clear. Carrier Infinity and Performance coils develop microbial growth on the downstream side, which then blows into the living space. We clean the coil, treat it with an antimicrobial, and verify with video before we call the job done.
- Sagging flex duct connections at the plenum. In humid attics across Katy, Cypress, and The Woodlands, flex duct connections to Carrier plenums sag or separate. That pulls attic dust, blown-in insulation, and oak pollen directly into the supply runs. We find this on Carrier Comfort systems and builder-grade installs more than any other setup. We reseat, seal with mastic, and rebalance airflow.
- Slab duct contamination in older Carrier homes. Houses in Meyerland and Sharpstown built in the 1960s and 70s often have original galvanized ductwork running through the slab. It leaks, it corrodes, and it collects decades of dust and debris. Carrier air handlers paired with these ducts work harder and cycle more particulates. We run a video scope through the full run before and after cleaning so you see the result, not just a receipt.
- Post-Harvey silt and sediment in return ducts. We routinely find Carrier systems in Bellaire and Meyerland where the air handler was replaced after Harvey, but the original ductwork still holds dried silt inside the return plenum. That silt hardens around the blower wheel, throws static pressure errors on Infinity controls, and keeps recontaminating the system. Cleaning the ducts without addressing the return plenum is half a job.
Carrier Service in Houston: What Local Conditions Mean for Your Equipment
Houston’s post-Harvey building code requires flood-damaged HVAC ducts to be replaced if the system was submerged. Yet we routinely find homes in Meyerland and Sharpstown where only the air handler was swapped, and the original Carrier ductwork still holds dried silt and mold spores. That’s a liability unique to this city’s flood history. No other metro in Texas has this combination of high humidity, a long cooling season, and a flood event that left sediment in tens of thousands of duct systems.
What that means for Carrier owners is simple. If your home flooded during Harvey and the ducts were never replaced, the system is circulating particles from 2017 every time the blower runs. A new Carrier air handler doesn’t fix that. The ducts have to be scoped, cleaned, or replaced. In one Sharpstown ranch on Bissonnet, Roy’s tech pulled a Carrier Performance air handler and found the return plenum lined with a half-inch of dried Harvey silt hardened around the blower wheel. We ran a 200-foot video scope through the slab ducts, cleaned the entire supply and return system, treated the evaporator coil with an antimicrobial, and sealed every boot with mastic. Then we rebalanced the airflow so the Infinity control stopped throwing static pressure errors. That’s the kind of job you can’t quote over the phone, and it’s exactly why Houston Carrier owners call us after two or three other companies have walked away.
Clean air doesn’t announce itself. You just stop noticing the problem.
Carrier Models & Products We Service in Houston
We work on every Carrier line commonly installed in Houston homes. The Infinity Series, with its matched coils and communicating controls, needs precise airflow to operate correctly. Performance Series air handlers and heat pumps are the most common mid-tier units we see in Houston suburbs. Comfort Series builder-grade units show up in subdivisions across Katy, Humble, and Spring, often with original flex duct from the day the house closed. We also service legacy Carrier builder models from the 1980s through the 2000s, which are still running in older Houston homes with original galvanized ductwork.
For parts, we take a blunt approach. We install OEM Carrier replacement parts when a component is under warranty or critical to airflow. That includes blower wheels and control boards. For duct sealing and insulation, we use commercial-grade mastic and closed-cell wrap because builder spec isn’t good enough for Houston’s humidity. On coil cleaning versus replacement, we always quote both options. Carrier coils that saw floodwater often fail within weeks if they weren’t fully neutralized, and we’d rather tell you that up front than sell you a cleaning that won’t hold.
We also handle video inspection on every job, evaporator coil cleaning for the humidity-driven growth we see across Houston, and our Dryer Vent Cleaning in Houston along with flex duct repair for sagging or separated connections. These aren’t add-ons for us. They’re part of doing the job right in this city.

| Evaporator coil cleaning (with duct cleaning) | $150 – $250 |
| Video inspection only | $95 – $150 |
| Flex duct repair or reseal per connection | $75 – $150 |
These are whole-system prices, not per-vent teaser quotes. The cost depends on house size, number of returns, duct length, and how long it’s been since the last cleaning. A 1,600-square-foot ranch in Meyerland with original slab ducts will run differently than a 3,000-square-foot two-story in The Woodlands with flex runs. Every estimate is free, it’s in writing, and it doesn’t change once we start. Call (713) 936-5800 and we’ll give you an exact number for your Carrier system.

FAQs – Carrier Air Duct Cleaning in Houston
Carrier’s maintenance guidance calls for regular inspection of ductwork and air handlers, and in Houston’s climate, that inspection usually leads to cleaning every 3 to 5 years at minimum. High humidity, year-round cooling demand, and heavy pollen loads from pine, oak, and ragweed mean ducts here accumulate organic material faster than in drier cities. If you’ve never had them cleaned and the house is older than a decade, call (713) 936-5800 for a video inspection. It’s the cheapest way to know what you’re actually breathing.
Yes, often. Flex duct that’s sagging or separated at the plenum can be reseated, resealed with mastic, and rebalanced. We also repair torn or crushed sections when the inner liner is intact. What can’t be repaired is flex duct that has mold growth inside the liner or is too degraded to hold air. In a Katy attic with high humidity and summer temperatures over 120 degrees, flex duct ages faster than the rest of the system. We scope it, show you what we found, and quote repair or replacement based on what’s actually there. Call (713) 936-5800 for an exact quote.
Yes. Infinity systems use communicating controls that measure static pressure, and leaky ducts throw those readings off. We use commercial-grade water-based mastic on all metal-to-flex and boot connections, not foil tape. Foil tape fails in Houston attic heat. Mastic stays flexible and holds. After sealing, we rebalance the system so the Infinity control stops throwing static pressure errors. That step gets skipped by a lot of crews, and it’s the difference between a quiet system and one that keeps erroring out.
Absolutely. In most Houston two-story homes, the upstairs unit and ductwork sit in the attic, which runs 130 degrees in July. Downstairs systems are often in a closet or garage, running through the slab or a crawl space. Upstairs flex runs sag, separate, and pull in attic heat and insulation. Downstairs slab ducts collect moisture and dust. A single cleaning quote for both floors without looking at either is guesswork. We scope both systems separately and price them based on what each one actually needs. Call (713) 936-5800 for a free assessment.
It depends on what’s inside them. If silt and mold spores are dried into the duct lining, cleaning can remove them, but the ducts may need replacement if the material is degraded or contamination is too deep. Houston code requires replacement if the system was submerged, but many homes slipped through with only a new air handler. We run a video scope first, show you the footage, and give you a written recommendation. Never a pressure close. Call (713) 936-5800 and Roy’s crew will walk you through what your ducts actually look like.
