HVAC Cleaning in Houston, TX

Fast, Reliable HVAC Cleaning Across Houston

HVAC cleaning in Houston typically runs $275–$650 for a full system service and is usually completed in a single visit. Most Houston homes need deeper cleaning than standard duct-only services because our Gulf Coast climate creates contamination patterns that dry-climate crews simply don’t encounter.

Call (855) 683-5929

We’re Lone Star Air Duct Cleaning Service Houston, and our HVAC Cleaning team has been working Houston duct systems for two decades. Scott Gray, our owner and lead technician, has personally cleaned air handlers in homes from Bellaire to Aldine, from 1970s ranch houses off I-10 to century-old bungalows in the Heights. When you call (855) 683-5929, you’re talking to the same person who’ll show up with the Rotobrush and Nikro HEPA vacuum — not a dispatcher sending out a rotating subcontractor crew. We know which ZIP codes flood first, which neighborhoods have the oldest galvanized trunk lines, and why a standard cleaning protocol from Dallas or Phoenix will miss half the problem in a Houston system.

Why Lone Star Air Duct Cleaning Service Houston Is Houston’s Preferred HVAC Cleaning Company

Our reputation here is built on 433 verified reviews averaging 4.9 stars — that’s not volume for volume’s sake, it’s proof that Houston homeowners recognize the difference when the owner himself is the one crawling through their attic with a borescope. Scott Gray has spent 20 years in the air duct cleaning trade, and he’s the lead technician on every job we run.

Response time matters in this humidity. We typically schedule Houston appointments within 24–48 hours because we know that a mold colony in a wet evaporator plenum doesn’t wait for a convenient booking window. Our equipment roster — Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies negative air machines — is the same gear used on commercial remediation jobs across Harris County. From cleaning to sealing to sanitizing, we handle the full scope so you don’t need a second contractor.

Our HVAC Cleaning Services in Houston

Evaporator Coil Cleaning

Houston’s persistent humidity keeps evaporator coils chronically wet through our 9–10 month cooling season. That moisture breeds mold and bacteria that standard coil sprays won’t touch. We remove the coil assembly when accessible, clean with foaming agents that break down biological buildup, and apply UVC coil box treatments where chronic colonization has occurred. In a Montrose bungalow built in 1948, we found the original galvanized sheet-metal trunk had rusted through at the coil plenum from decades of condensate overflow; we replaced the plenum, sealed the remaining trunk with mastic, and treated the entire system with a UVC coil box to suppress the chronic mold that had been causing allergic reactions.

Coil Treatment

After cleaning, we apply antimicrobial treatments specifically formulated for Houston’s high-humidity environment. These aren’t generic sprays — they’re designed to resist wash-off from the heavy condensate production our coils generate. For homes in flood-prone areas like those near Brays Bayou or along White Oak Bayou, we use enhanced protocols that address post-flood contamination from events like Hurricane Harvey’s 2017 inundation of roughly 154,000 structures. Standard protocols used in drier markets entirely fail to address this failure mode.

Air Handler Cleaning

The air handler is where Houston’s two climate enemies — extreme attic heat and Gulf moisture — converge. In unconditioned attics across Memorial, Spring Branch, and the Energy Corridor, summer temperatures routinely exceed 140°F. That heat degrades the foil facing and mastic at duct connections, creating gaps that pull in attic air loaded with fiberglass particles and moisture-laden outside air. We clean the blower assembly, housing, and return plenum, then seal connection points with fresh mastic to restore system integrity.

Blower Cleaning

A dirty blower wheel in Houston doesn’t just move less air — it becomes a distribution point for whatever’s growing upstream. We remove and clean blower assemblies with compressed air and contact cleaners, balance the wheel, and inspect the motor bearings for moisture damage common in our high-humidity installations.

Condenser Cleaning

Outdoor condensers in Houston battle more than dust. Salt air from the Gulf accelerates coil corrosion in homes south of I-10 and east of 288, while cottonwood fluff and pollen from our extended growing season clog fins. We clean coils with foaming agents, straighten damaged fins, and check refrigerant levels — because a struggling condenser means longer run times and more moisture stress on the entire system.

Heat Exchanger Cleaning

During our brief heating season, Houston’s heat exchangers accumulate the same dust and microbial loading as our cooling components. We inspect with borescopes and clean with rotary brushes and HEPA-contained vacuums, checking for rust-through from condensate that didn’t drain properly during our humid shoulder seasons.

Trusted Brands We Service in Houston

We maintain working knowledge of Honeywell, Aprilaire, and Guardsman air quality components commonly installed in Houston homes — media filters, electronic air cleaners, UV treatment systems, and whole-home humidifiers that require calibration for our climate. We don’t sell parts you don’t need, but when a Montrose homeowner’s 1980s Honeywell media cabinet needs a retrofit, or a West University Place install needs Aprilaire humidifier pads sized for our moisture load, we stock or source quickly. Our Nikro and Rotobrush equipment interfaces with these systems without cross-contaminating clean components.

Common HVAC Cleaning Problems We See in Houston Homes

• Flex duct degradation in unconditioned attics. The 1970s–1990s suburban explosion built thousands of Houston homes with flex duct routed through attics where 140°F+ summer heat cooks the foil facing and adhesive. We regularly find disconnected runs in neighborhoods like Clear Lake, Kingwood, and Sugar Land that have been pulling attic air for years.
• Chronic evaporator wetness and downstream mold. Our 9–10 month AC season means coils and return plenums stay wet enough for mold and bacteria to colonize and spread through the entire duct system. Sanitizing treatments are standard here, not an optional upsell.
• Post-flood contamination in Harvey-impacted structures. The 2017 storm inundated roughly 154,000 Houston structures. Ducts that had standing water inside them require specialized remediation protocols — standard cleaning won’t address the microbial loading or residual sediment.
• Industrial particulate in east Houston corridors. Homes in Galena Park, Pasadena, Channelview, and Deer Park sit downwind of the Ship Channel’s petrochemical refineries. Technicians working those ZIP codes consistently pull filters and duct interiors coated with a dark, oily residue unlike anything in the west or northwest suburbs. Residents call disproportionately about persistent chemical odors from their vents even when ducts appear visually clean.
