Trusted Air Duct Cleaning for San Antonio Homeowners
Air Duct Cleaning in San Antonio typically costs between $350 and $700 for a full system cleaning of an average 2,000-square-foot home, and most jobs are completed in three to five hours. The work removes years of accumulated dust, pet dander, pollen, and construction debris from the ductwork that carries heated and cooled air through your house. If your vents have never been cleaned, or if you’ve recently completed a renovation, the air moving through your San Antonio home is picking up everything sitting in those ducts and circulating it through every room.

Garrison Partners, led by Preston Harley, has built its reputation on showing up when we say we will and doing the work the way it should be done. Every air duct cleaning job in San Antonio starts with a written price before any equipment comes off the truck. You’ll know exactly what the service costs, what it includes, and how long it will take.

What Our Air Duct Cleaning Service Includes
Air duct cleaning is not a single pass with a shop vac. Done properly, it’s a methodical process that addresses every surface air touches between your HVAC unit and the register in each room. We clean the supply and return ducts, the main trunk lines, the branch runs, and the components that most companies skip. Here’s what each piece of the job involves.
Supply and Return Duct Cleaning
Your supply ducts deliver conditioned air to every room in the house, and your return ducts pull air back to the HVAC unit to be heated or cooled again. Both sides accumulate dust, hair, and debris over time, and in San Antonio’s climate, that debris often includes fine dust blown in from outside. We use high-powered negative air machines and agitation tools to dislodge and extract buildup from the full length of both duct runs, not just the first few feet you can see from the register.

Register and Grille Cleaning
Every supply register and return grille in your home is a collection point for dust, cooking grease, and pet hair. We remove each register, clean both sides thoroughly, and wipe down the surrounding opening before reinstalling it. This step matters because a clean duct run feeding air through a dirty register undoes the entire point of the service. You’d be surprised how much buildup sits on the back side of a register that looks fine from the living room.

Blower Motor and Fan Cleaning
The blower motor is the component pushing air through your entire duct system, and it collects a layer of dust that reduces airflow and forces your HVAC system to work harder than it should. We access the blower compartment, clean the fan blades and housing, and check for visible wear while we’re in there. A clean blower moves more air with less strain, which matters during San Antonio summers when your system runs nearly nonstop.

Evaporator Coil Cleaning
If the evaporator coil is dirty, your system loses efficiency and your home loses comfort. The coil sits in the airflow path, and when it’s coated with dust and grime, it can’t transfer heat effectively. We inspect and clean the coil as part of the service when it’s accessible, removing the layer of buildup that reduces cooling performance and drives up your electric bill during the hottest months of the year.

Plenum and Filter Housing Cleaning
The plenum is the large box that connects your supply and return ducts to the HVAC unit itself. Dust and debris settle in the plenum before it ever reaches the branch lines, which means a dirty plenum keeps reintroducing particles into your air even if the rest of the system is clean. We clean the plenum interior, inspect the filter housing, and confirm that your system is drawing air through a filter that actually fits the slot. A poorly fitted filter lets unfiltered air bypass entirely, and we see that issue in San Antonio homes more often than most homeowners would expect.

Brands We Service for Air Duct Cleaning
Ductwork is ductwork, but the HVAC systems that push air through it vary by manufacturer, and we work on all of them. Whether your San Antonio home has a Carrier, Trane, Lennox, Rheem, Goodman, or American Standard system, our cleaning process is designed around the way your specific equipment is configured. We’ve cleaned ducts connected to every major brand of furnace, heat pump, and air handler installed in Texas homes over the past several decades.
If your garage door opener is a Wayne Dalton or Craftsman unit, you already know that brand-name equipment demands brand-specific attention. The same principle applies to your HVAC system. We understand how different manufacturers route airflow, where their access panels sit, and how to clean the system without damaging sensitive components. Whether you have a high-efficiency Trane heat pump or an older builder-grade Goodman unit, the service applies the same standard. And if you’re not sure what brand you have, that’s fine. We’ll identify it when we arrive and adjust the approach accordingly.
Signs You Need Air Duct Cleaning Right Now
- Visible dust buildup around registers. If you wipe a register clean and it’s coated again within a few days, the dust is coming from inside the duct, not from normal household activity. That buildup is a clear signal that the duct interior is loaded and pushing particles into your living space every time the system runs.
- Uneven airflow between rooms. Some rooms stay comfortable while others never quite reach the thermostat setting. In San Antonio homes, we frequently find that restricted ducts packed with years of debris are the culprit, not a failing HVAC unit. Cleaning restores balanced airflow and evens out temperatures room to room.
- Higher cooling bills with no change in usage. A dirty coil and restricted ducts force your system to run longer cycles to hit the same temperature. If your CPS Energy bill has crept up through the spring and summer without a change in your habits, the air pathway itself is likely part of the problem.
- Dust accumulating on surfaces faster than expected. You dust the living room on Sunday and by Wednesday it looks like you never touched it. That fine layer is often recirculated dust from inside the duct system. Cleaning the ducts reduces the volume of particles entering your rooms in the first place.
- Renovation or new construction debris in the vents. Drywall dust, sawdust, and insulation particles from a remodel or new build in San Antonio settle into open ducts during construction and stay there. If you’ve had work done recently and the vents were not sealed, the debris is in the system and moving through your air. This is one of the most common reasons we’re called out to newer homes and recently updated older ones.
Our Air Duct Cleaning Process – Step by Step
We don’t rush this job, and we don’t cut corners. The process follows a set sequence that ensures every section of ductwork gets cleaned, the system gets verified, and your home is left the way we found it. The Garrison Standard applies at every step, and the price you approved before we started is the price you pay when the job is done.
- 1
Inspection and system assessment. Before we touch anything, we inspect the system. We check the filter condition, look at the return and supply plenums, identify the access points, and note any visible damage or gaps in the ductwork. This step confirms what needs cleaning and alerts us to any issues you should know about. We walk you through what we find before any cleaning begins.
- 2
Sealing off supply registers and connecting the negative air machine. We create negative pressure in the duct system using a high-powered vacuum unit connected at the plenum. This pulls air toward the machine and prevents debris from blowing back into your living space during cleaning. Each supply register is blocked to maintain proper pressure differential throughout the system.
- 3
Agitation and extraction of duct debris. Compressed air agitation tools are inserted into the ducts to dislodge dust and debris from the interior walls of the ductwork. The running negative air machine captures everything that shakes loose. We work section by section through the main trunk and each branch run until the system is clear from end to end.
- 4
Component cleaning. The blower motor, fan housing, evaporator coil, and plenum interior are cleaned by hand where accessible. These components hold a significant share of the system’s accumulated dust and are usually the most neglected. Cleaning them is what separates a surface-level job from a full system cleaning.
- 5
Final walkthrough and system verification. We remove our equipment, reinstall any access panels, restore the registers, and confirm the system is operating correctly. You see the work before we leave, and we answer any questions about what was done. If anything doesn’t meet the standard, we address it on the spot, not next week.
How Much Does Air Duct Cleaning Cost in San Antonio?
Air duct cleaning in San Antonio runs $350 to $700 for a complete system cleaning on a typical home, depending on the size of the house, the number of vents, the age of the system, and how long it’s been since the last cleaning. Homes with extensive buildup, multiple HVAC systems, or inaccessible duct runs will land at the higher end of that range. A single system in a 1,500-to-2,500-square-foot home usually falls between $400 and $550.

Several factors move the price. System size and vent count are the most straightforward: more ducts mean more time and labor. Accessibility matters too. Attic ductwork in a San Antonio summer is a difficult workspace, and units in tight closets take longer to clean properly. The level of contamination is the final variable. A system that’s been cleaned in the last three to five years is faster to restore than one that hasn’t been touched since the house was built.
Avoid overpaying by being wary of any quote under $99. That price covers a quick vacuum of the register openings, not a full duct cleaning, and it will not solve the problem. Get a written price before any work starts, and make sure the quote lists what’s included: supply and return ducts, registers, blower, coil, and plenum. Our free estimate gives you the full scope and the full price in writing before you approve anything. The number on the quote is the number you pay.

Frequently Asked Questions – Air Duct Cleaning in San Antonio
Air duct cleaning removes accumulated dust, debris, pet dander, and contaminants from the inside of your home’s ductwork, including supply and return ducts, registers, the blower motor, and the evaporator coil. The process uses negative-pressure equipment and agitation tools to dislodge and extract buildup without releasing it into your living space. The result is cleaner air moving through your San Antonio home and a more efficient HVAC system. It’s recommended every three to five years for most households, and sooner after major renovations.
Most air duct cleaning jobs in San Antonio take three to five hours from arrival to final walkthrough, depending on the size of the home and the number of HVAC systems. A single-system house under 2,000 square feet can often be completed in about three hours. Larger homes, multiple units, or heavily contaminated systems may extend toward a full day. We’ll give you a time window before we start and stick to it.
You can expect to pay $350 to $700 for a full air duct cleaning on a typical San Antonio home, with most single-system jobs landing between $400 and $550.
