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 in Friendswood, TX
HVAC cleaning in Friendswood typically runs $280-$520 for a full system, and every job starts with a written price before we touch a single panel. We’re CleanRun Duct Repair & Cleaning, and we serve Friendswood from our Houston office with crews that know the local housing stock - the 1970s-1990s flex duct systems, the post-Harvey rebuild patchwork, and the humidity that keeps attics wet eight months a year. Call (346) 251-8919 for a free written estimate.
Why Friendswood Homes Are Different
Friendswood sits on the Gulf Coast plain between Houston and Galveston Bay, where summer dew points climb above 75°F and AC systems run nearly nonstop from April through October. That sustained humidity collects condensation inside flex ducts, especially in poorly insulated attic runs, accelerating mold growth that makes duct cleaning medically relevant here in ways it isn’t in drier inland Texas.
The housing stock tells its own story. Most homes are suburban tract builds from the late 1970s through the 1990s, now 30-45 years old, with flex duct systems prone to sagging, disconnection, and microbial buildup. Hurricane Harvey in 2017 added another layer: Clear Creek overflow inundated hundreds of homes, and even thorough remediation often overlooked attic-run ductwork. Contractors focused on walls and flooring while residual moisture, mold colonies, and flood-borne contaminants stayed circulating through HVAC systems. In subdivisions backing Clear Creek or its tributaries, floodwater entered attic spaces and saturated insulation wrapped around flex ducts. Many homeowners replaced flooring and drywall but never had the ductwork inspected, leaving hidden mold that resurfaces every cooling season when condensation feeds remaining spores.
Our Main Friendswood Services
These are the services Friendswood homeowners call about most.
Air Duct Cleaning in Friendswood
We clean the full duct network - supply and return runs, plenum (the central distribution box), and registers (the room vents) - using negative-pressure extraction (suction that pulls debris out rather than pushing it deeper). In Friendswood, we regularly find post-Harvey sediment and mold in attic flex lines that homeowners assumed were replaced during rebuilds. Every run is photographed before and after. Air Duct Cleaning in Friendswood

Dryer Vent Cleaning in Friendswood
Lint accumulation in dryer vents is a fire hazard and efficiency killer. In Friendswood’s older subdivisions with longer vent runs through attics, we see blockages that add 20-30 minutes to dry cycles. We clear the full run from appliance to exterior termination and verify airflow with a meter reading. Dryer Vent Cleaning in Friendswood

Duct Repair & Sealing in Friendswood
Sagging flex duct, disconnected joints, and rodent damage are common in Friendswood’s 30-45-year-old systems. We repair or replace damaged sections and seal leaks with mastic (a brush-applied sealant that outlasts tape). Post-Harvey rebuilds often left original ductwork patched rather than properly integrated. Duct Repair & Sealing in Friendswood

AfterHVAC Cleaning in Friendswood

HVAC cleaning in Friendswood addresses the full climate-control system, not just the ducts. The combination of 30-45-year-old flex duct, post-Harvey contamination legacy, and eight months of annual humidity creates conditions we don’t see in drier markets. Evaporator coils in Friendswood attics often carry mold loads from years of condensation cycling, and blower assemblies collect the debris that bypassed aging filters. HVAC Cleaning from CleanRun includes the full system assessment, written scope, and documented photo record.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or musty odor when the AC first cycles on.
What it costs in Friendswood
Evaporator coil cleaning typically runs $180-$340.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the fins before and after.
Blower Cleaning
Signs you need it
Dust puffing from registers at startup, uneven room temperatures, or blower motor running louder than previous seasons.
What it costs in Friendswood
Blower assembly cleaning typically runs $140-$260.
How we do it
We remove the blower housing, clean the squirrel cage and motor housing with compressed air and solvent, balance the assembly, and reinstall with torque-checked fasteners.
What HVAC Cleaning Costs in Friendswood
| Item | Typical range in Friendswood |
|---|---|
| Full HVAC system cleaning | $280-$520 |
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $140-$260 |
How do I know my HVAC system needs cleaning, not just the ducts?
If you smell must when the AC cycles on, see ice on refrigerant lines, or notice weak airflow despite clean filters, the coil or blower likely needs attention. Call (346) 251-8919 and we’ll scope it with a camera.
Can HVAC cleaning fix the musty smell in my Friendswood home?
Yes, if the source is microbial growth on the coil or in the plenum - common here after humid summers. We photograph the source so you can see it before we clean.
Air Quality & Sanitizing in Friendswood

Air quality work in Friendswood targets the contaminants that survive standard cleaning. Post-Harvey mold colonies, bacteria from years of condensation cycling, and the persistent must that returns each spring - these need more than vacuum extraction. Air Quality & Sanitizing from CleanRun includes treatment verification and the documented photo record.
Mold Treatment
Signs you need it
Visible mold around registers, recurring musty odor after duct cleaning, or allergy symptoms that worsen when the system runs.
What it costs in Friendswood
Mold treatment typically runs $220-$450.
How we do it
We apply EPA-registered antimicrobial to affected duct runs and the plenum, run contact plates to verify reduction, and include the lab-style documentation in your job record.
UV Light Installation
Signs you need it
Repeated mold recurrence despite cleaning, or a household member with compromised immunity who needs continuous suppression.
What it costs in Friendswood
UV light installation typically runs $320-$580.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp in the supply plenum, wire to the air-handler circuit, and show you the bulb-change schedule.
What Air Quality & Sanitizing Costs in Friendswood
| Item | Typical range in Friendswood |
|---|---|
| Mold treatment | $220-$450 |
| Bacteria sanitizing | $180-$340 |
| UV light installation | $320-$580 |
Is mold treatment necessary if I already had duct cleaning?
Standard duct cleaning removes loose debris but doesn’t kill mold adhered to duct walls. If your Friendswood home flooded during Harvey or Imelda and the ductwork wasn’t replaced, treatment is likely warranted. Call (346) 251-8919 for a camera inspection.
How long does UV light installation take?
Most residential installs take 2-3 hours, including wiring to the air handler and testing. We schedule these during weekday mornings to minimize disruption.
Brands We Service in Friendswood
We stock parts and service equipment from Honeywell, Aprilaire, Rotobrush, and other major manufacturers. Most filter and media replacements ship same-day from our Houston office, and crews carry common UV lamps and antimicrobial formulations on every truck. See our brands for the full list.
