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.
Air Duct Cleaning Company in Friendswood, TX
Air duct cleaning in Friendswood, TX typically runs $350 – $650 for a whole-home system and addresses a problem most inland cities don’t face: moisture-driven microbial growth inside ductwork, not just dust buildup. We’re Hollis Air Duct Cleaning, and we’ve learned that Gulf Coast humidity changes everything about how ducts get dirty and how they need to be cleaned. Call us at (361) 326-5060 for a written estimate before any work starts.
Why Friendswood Homes Are Different
Friendswood sits in the Gulf Coast humidity corridor where HVAC systems run nearly year-round, so air ducts here accumulate a distinct mix of mold and mildew spores, not just dust. That makes duct cleaning less about dust removal and more about moisture-driven microbial growth that homeowners deal with after every hurricane-season deluge. The city’s strict drainage and floodplain history along Clear Creek means many homes have had water intrusion that feeds hidden duct contamination, a pattern we see across the 77546 ZIP code.
The housing stock tells the rest of the story. Most Friendswood homes were built between the 1970s and 1990s, ranch-style and two-story brick on large lots, with newer custom builds in West Ranch and Sterling Creek. Those older homes often still run original flex duct or sheet-metal trunk lines that harbor debris and mold after decades of coastal humidity. Newer tight construction traps that same moisture and recirculates it. After a tropical storm or flood event, we routinely find mold growth in the first few feet of main trunk lines where cool air meets warm, humid attic air. That failure mode spikes in the weeks following named storms and drives calls from neighborhoods near Clear Creek.
Our Main Friendswood Services
Most calls we get from Friendswood homeowners fall into three categories. Each has its own page with full pricing, process details, and local conditions.
Air Duct Cleaning in Friendswood
We clean the full supply and return system with a Rotobrush rotary brush and negative-air extraction, pulling debris and microbial growth out of trunk lines, branch ducts, and registers. In Friendswood, we pay special attention to the first few feet of main trunk lines where condensation pools after humid spells. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Friendswood covers the full process and what to expect.

Dryer Vent Cleaning in Friendswood
Lint buildup in dryer vents is a fire hazard anywhere, but in Friendswood the Gulf Coast humidity makes clumps of lint stick to duct walls more stubbornly than in drier climates. We run a rotary brush through the full vent length and check exterior termination points, which get blocked by pollen and storm debris more often here. Dryer Vent Cleaning in Friendswood has the details and pricing.

Duct Sealing in Friendswood
Leaky ducts pull humid attic air into the system, which in Friendswood means introducing mold spores and moisture directly into your living space. We seal joints and seams with mastic and mechanical fasteners, then pressure-test to verify the seal holds. Tight ductwork also cuts the load on your AC, which matters when it runs ten months a year. Duct Sealing in Friendswood explains how we test and what improvement you can measure on your bill.
