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.

AfterTrusted HVAC Cleaning for Katy Homeowners
HVAC cleaning in Katy typically addresses the components your standard duct cleaning doesn’t reach: the evaporator coil, blower assembly, condenser, air handler, and heat exchanger. If you’re wondering how much HVAC Cleaning costs, a complete system cleaning runs $280-$680 depending on which components need attention, and every job starts with a written price before we touch a single panel. Call (346) 666-7165 for a free estimate with no obligation.
We’ve been cleaning HVAC systems in Katy since 2013, and we’ve documented the inside of over 52,000 units. The photo record from a typical Katy job in July 2024 showed a 2.3-inch debris mat on the evaporator coil of a 2019-built home in Cinco Ranch - the homeowner had changed filters religiously, but the coil was still choking. That’s what HVAC cleaning is for: the parts filters can’t protect.
CleanRun Air Duct Cleaning Katy operates under the H.A.V.E.N. Standard, with background-checked, uniformed technicians who arrive identified by name. Every job includes a written price upfront, a Documented Photo Record of every component cleaned, and the 365-Day Done Right Promise backed in writing. We’re independently owned and operated, not a franchise, and we publish our license number so you can verify status directly with the state.
What Our HVAC Cleaning Service Includes
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler and absorbs heat from your home’s air - when it’s coated in dust or biofilm, your system runs longer, your bills climb, and your compressor takes the strain. In Katy, we regularly find coils packed with pollen from the area’s heavy oak and pine seasons, plus the fine caliche dust that blows in from west Texas construction. Our crews use foaming cleaners and low-pressure rinsing to restore heat transfer without bending the delicate aluminum fins, and we photograph the coil before and after so you can see the difference between our work and a quick chemical spray.
Blower Cleaning
The blower assembly - the fan and motor that push conditioned air through your ductwork - collects debris that throws off balance and reduces airflow by 15% or more in a typical Katy home. We remove the blower housing, clean each blade individually, and inspect the motor bearings for wear. A blower caked with pet hair and drywall dust, common in newer Katy subdivisions like Brookshire and Pecan Grove, doesn’t just move less air; it draws more amperage and shortens the motor’s life. Our Documented Photo Record shows you exactly what was removed.
Condenser Cleaning
Your condenser unit sits outside, and in Katy’s climate it battles cottonwood fluff, grass clippings, and the fine grit that settles after every Gulf Coast storm. We disconnect power, remove the top grille, and clean the coils from the inside out using a fin comb and controlled water pressure - never a pressure washer, which folds the fins flat and destroys efficiency. A clean condenser in Katy can drop your system’s head pressure by 20-30 psi, which translates to real savings on August afternoons when the heat index pushes 110.
Air Handler Cleaning
The air handler is the metal box that houses your coil, blower, and often your heat strips or heat exchanger - it’s the central station of your HVAC system, and when it’s dirty, everything downstream suffers. We clean the interior cabinet, the drain pan and condensate line (a clogged line in Katy humidity means water damage fast), and all accessible surfaces. Our crews carry wet-dry vacuums with HEPA filtration and antimicrobial treatments for the drain pan, and we document the cabinet condition before we start and after we finish.
Heat Exchanger Cleaning
The heat exchanger separates combustion gases from your breathing air in gas furnaces - it’s a safety-critical component, not just an efficiency concern. We inspect for cracks, corrosion, and soot buildup using a borescope camera, and we clean only where appropriate and safe to do so. In Katy’s older homes, particularly in neighborhoods like Old Katy and the original Mission Bend subdivisions, we’ve found heat exchangers with decade-scale carbon deposits that required replacement, not cleaning. We tell you which it is, show you the camera footage, and put the recommendation in writing.
Coil Treatment
After cleaning, we apply a non-acidic, EPA-registered coil treatment that inhibits microbial growth without leaving a residue that restricts airflow. This isn’t a perfume mask - it’s a surface treatment that extends the time between necessary cleanings, particularly valuable in Katy’s humid months when condensate lines run constantly and biological growth thrives. We use treatments compatible with the coil manufacturer’s specifications, and we note the product applied in your written job record.

Brands We Service for HVAC Cleaning
We’ve cleaned HVAC components from every major manufacturer installed in Katy homes. On Carrier and Trane systems - common in homes built 2015-2020 in Cinco Ranch and New Territory - we’ve serviced hundreds of units and maintain familiarity with their proprietary coil geometries and fastener placements. Lennox and Rheem equipment, frequently found in the Brookshire and Richmond markets, each has its own blower assembly design that affects cleaning time and access; our crews carry the tool sets for both. Goodman and York units, often the original equipment in Mission Bend and Four Corners subdivisions, require particular attention to condenser fin spacing during cleaning.
We also regularly service American Standard, Bryant, Ruud, Amana, and Daikin systems. Whether you have a 2023 high-efficiency variable-speed unit in Pecan Grove or a 2012 single-stage system in Jersey Village, we can clean it properly, document the work, and stand behind it with the 365-Day Done Right Promise. If you’re unsure what’s installed, we’ll identify it during your free estimate and explain what the cleaning involves before quoting a price.
BeforeAfterSigns You Need HVAC Cleaning Right Now
- Your energy bills have climbed without a rate increase. A dirty evaporator coil or blower can reduce system efficiency by 20% or more, and in Katy’s climate that shows up in your June-September bills first. We’ve had homeowners in Meadows Place and Sugar Land report $40-$80 monthly drops after full HVAC cleaning.
- Some rooms never reach the thermostat setting. Restricted airflow from a dirty blower or coil often manifests as temperature stratification - the master bedroom stays hot while the living room cools fine. This isn’t always a duct problem; sometimes the system simply can’t move enough air.
- You smell mustiness when the system cycles on. That odor is microbial growth on the coil or in the drain pan, thriving in Katy’s humidity. It’s not just unpleasant - it’s an indicator that the coil’s surface is compromised and airflow is restricted by biofilm.
- The system runs constantly but never satisfies. Long run cycles with poor results point to a capacity problem, and a choked coil is the most common cause we find in Katy homes where the ductwork was cleaned recently but the HVAC components were ignored.
- Visible dust blows from registers right after filter changes. If you’ve upgraded to a pleated filter and still see debris, the source is likely downstream - a dirty blower flinging accumulated particles, or a coil shedding flakes into the airstream.
Our HVAC Cleaning Process - Step by Step
- 1
Arrival and system assessment. Our technician arrives in a marked CleanRun vehicle, introduces themselves by name, and performs a visual inspection of your indoor and outdoor units. We note the manufacturer, model, approximate age, and any obvious concerns - rust, refrigerant oil stains, or previous repair evidence. This takes 10-15 minutes and costs nothing.
- 2
Written price delivered before work begins. Based on what we find, we provide a written scope and price for your approval. Haven Standard Clause 1: no work starts without a written price agreed to by both parties. If you decline, you owe nothing for the assessment.
- 3
Component disassembly and documentation. We photograph each component before cleaning - the coil, blower, condenser fins, air handler cabinet, and heat exchanger if accessible. These images become your Documented Photo Record, delivered with your invoice.
- 4
Cleaning with trade-specific tools. Coils get foaming cleaner and controlled rinse; blowers get hand-cleaned blade by blade; condensers get fin combing and gentle pressure washing from the inside out. We use Rotobrush agitation equipment for stubborn deposits and Guardsman treatments where antimicrobial protection is appropriate. Every tool and product is noted in your job record.
- 5
Reassembly, testing, and final documentation. We reassemble, restore power, verify operation, and photograph the cleaned components. The after photos go into your record alongside the befores. You receive the complete file by email, plus the written 365-Day Done Right Promise. If anything isn’t right, we make it right - backed in writing, not subject to manager discretion.
How Much Does HVAC Cleaning Cost in Katy?
A typical evaporator coil cleaning in Katy runs $180-$340. Blower cleaning adds $120-$220. Condenser cleaning ranges $140-$260. A complete air handler cleaning, which includes coil, blower, and cabinet, generally falls between $280-$480. Heat exchanger inspection with cleaning where appropriate runs $160-$280, and coil treatment applied after cleaning adds $60-$120. A full-system HVAC cleaning covering all accessible components typically ranges $480-$680 for standard residential equipment.
Several factors move the price within these ranges. System accessibility matters: a coil buried in a tight attic in an older Katy home takes longer than one in a spacious utility closet in a new build. Component condition affects time - a coil with three seasons of pollen mat requires more labor than one maintained annually. And equipment type varies: a two-stage variable-speed blower has more parts to clean than a single-stage PSC motor.
What doesn’t affect the price is how many vents you have. We don’t charge per vent or per register - Haven Standard Clause 1 means one flat price per system, agreed before work starts. The quote you approve is the invoice you pay.
To avoid overpaying, watch for these patterns: a quote that won’t commit to a number until the technician is in your home, a “whole house special” that doesn’t specify which components are included, or equipment that looks like a shop vacuum with a brush attachment. Professional HVAC cleaning requires disassembly, chemical application appropriate to the component, and controlled rinse or extraction - not a wand waved through a register.

Frequently Asked Questions - HVAC Cleaning in Katy
HVAC cleaning addresses the mechanical components of your heating and cooling system - the evaporator coil, blower, condenser, air handler, and heat exchanger - while air duct cleaning removes debris from the ductwork that distributes air through your home. Duct cleaning doesn’t clean the coil that actually cools your air, or the blower that moves it. Many Katy homeowners who’ve had “duct cleaning” elsewhere are surprised to learn their HVAC components were never touched. We offer both services and can assess which your system actually needs.
A single-component cleaning, such as an evaporator coil or condenser, typically takes 1.5-2.5 hours. A full-system cleaning covering all accessible components requires 3-5 hours depending on system size, accessibility, and condition. We don’t rush - Haven Standard Clause 4 requires that every component be photographed before and after, and that documentation takes time. We’ll give you a time estimate with your written price so you can plan accordingly.
Most homeowners in Katy pay between $280 and $680 for professional HVAC cleaning, depending on which components need attention and how accessible the equipment is. A basic condenser cleaning might run $140-$260, while a complete air handler with coil, blower, and cabinet cleaning typically falls at $280-$480. We deliver a written price before any work begins, and that price doesn’t change unless you request additional scope. Call (346) 666-7165 for an exact quote - estimates are free and carry no obligation.
We clean components from Carrier, Trane, Lennox, Rheem, Goodman, York, American Standard, Bryant, Ruud, Amana, Daikin, and virtually every other residential manufacturer installed in Katy-area homes. The cleaning process varies by design - a Lennox Merit series coil mounts differently than a Carrier Infinity - but our crews carry the tool sets and documentation for all common configurations. We’ll identify your equipment during the free estimate and confirm we can service it properly before quoting.
We don’t promise same-day completion because proper HVAC cleaning requires time, specific tools, and documentation that can’t be rushed. Most jobs are scheduled within a few business days of your estimate. If your system has failed completely and you need immediate assistance, we can refer you to a trusted HVAC contractor in our network for repair, then return for cleaning once the system is operational. Our focus is doing the work correctly, not doing it fast.
Every HVAC cleaning job is backed by our 365-Day Done Right Promise: if the work isn’t right, we make it right, backed in writing on every invoice. This isn’t a policy subject to manager approval - it’s a contractual commitment. If you notice reduced airflow, unusual odors, or any concern within a year of service, we return to inspect and correct at no charge. We also warrant that the components we cleaned were documented with before-and-after photography, so there’s no dispute about what was done.
Clear a 3-foot workspace around your indoor unit and outdoor condenser so our technician can access panels and tools safely. If your unit is in an attic, ensure the access hatch is unobstructed. We don’t need you to pre-clean or move furniture beyond the immediate work area. Pets should be secured, as we’ll be opening the system and using cleaning agents. We’ll confirm any specific needs when we schedule, and our technician will call 30 minutes before arrival so you’re not waiting.
