AfterFull System Cleaning in San Antonio, TX
Full system cleaning means every part of your HVAC air path gets cleaned, not just the main duct runs. A complete job covers supply ducts, return ducts, the air handler, blower fan, evaporator coil, drain pan, and both plenums. In San Antonio, where cedar pollen and limestone dust move through homes nearly year-round, most families in areas like Alamo Heights, Stone Oak, and Helotes see the biggest difference from a full system clean rather than a partial one. Mortons Air Duct San Antonio has provided this service since 2005, with a written price before any work starts and a 365-Day Done Right Promise on every job. Call (903) 354-8393 for a free estimate.
This is a deeper clean than a standard Air Duct Cleaning in San Antonio visit. Where a basic cleaning focuses on the ductwork itself, full system cleaning gets into the equipment that moves and conditions the air. That matters here because our hot, humid summers push AC systems hard, and the coil and blower collect grime that duct-only cleaning never touches.
When You Need Full System Cleaning
Most San Antonio homeowners call us for Air Duct Cleaning services when they notice one or more of these signs. If two or three sound familiar, a full system cleaning is usually the right call.
- Dust returns within days of cleaning surfaces. If you wipe a bookshelf on Tuesday and see a film by Friday, the system is circulating dust from the coil, blower, or return plenum, not just the ducts.
- One or more rooms stay noticeably warmer than the rest of the house. The blower and evaporator coil sit behind the filter, and when they’re coated, airflow drops. A full system clean restores air movement through every run.
- The house smells musty when the AC first kicks on. That odor typically comes from microbial growth on the coil or in the drain pan, especially after our humid spring and fall seasons. A duct-only clean leaves the source in place.
- You have pets that shed heavily. Hair and dander work past the filter and pack onto the blower wheel and coil fins. Full system cleaning removes buildup that standard duct cleaning skips.
- The system is five years old or older and has never had a full clean. Even in newer homes around Cibolo and Schertz, blower wheels and coils accumulate a layer of grime within a few seasons, and that layer cuts efficiency and shortens equipment life.
- You bought a home and can’t confirm when the HVAC was last cleaned. We see this often in older neighborhoods like Monte Vista and Jefferson, where previous owners kept no service records. A full system clean gives you a known starting point for air quality and equipment condition.
Our Full System Cleaning Process
We follow a set sequence on every full system cleaning job, and we walk you through the plan before the first tool comes off the truck. No surprises, no scope creep. Here’s exactly what happens.
- Walkthrough and written quote. Paul or one of our technicians inspects the system components and gives you a written price for the full scope of work before anything starts. That price is the price, even if the job takes longer than expected.
- Home protection setup. Shoe covers go on at the door, and drop cloths cover floors and any furniture near the work areas. Pet areas get extra care. If a baby or toddler is napping, we’ll work around the quietest tools until nap time is over.
- Supply and return duct cleaning. We connect professional negative-air equipment from Abatement Technologies to create a vacuum on the system, then agitate each duct run with powered brushes to release dust, hair, and debris from the walls of the ductwork. Everything moves out through the vacuum, never into the living space.
- Air handler, blower, and coil cleaning. This is where full system cleaning separates itself. We open the air handler, remove the blower assembly, and clean the wheel and motor housing. The evaporator coil gets a careful cleaning with products designed for coil surfaces, not household cleaners that can damage fins or leave residue.
- Drain pan and condensate line flush. San Antonio humidity means condensate lines work constantly. We clear and flush the pan and line so water flows freely and doesn’t back up into the system or the ceiling below.
- Final inspection and photo documentation. We test airflow at several registers, check the system operation, and take photos of the clean components and the work areas before we leave. You’ll see the finished job, floors included, before we go.
Full System Cleaning Pricing in San Antonio
Full system cleaning in San Antonio typically runs between $525 and $875 for a single system home, depending on the size of the house, the number of returns, and the condition of the coil and blower. Homes with two systems, common in larger two-story houses in places like Shavano Park or Fair Oaks Ranch, generally fall between $950 and $1,400. We give a written quote before any work begins, so you’ll know the exact number for your home before we touch anything.
What Affects the Cost
- Number of systems and zones. A two-story home with separate upstairs and downstairs units costs more because there’s twice the equipment to clean.
- Coil and blower condition. If the coil has years of packed buildup, it takes longer to clean properly. We’ll tell you what we see during the walkthrough.
- Access difficulty. Attic-installed air handlers in older San Antonio homes can take longer to reach, which reflects honestly in the quote.
- Duct count and layout. More supply runs and returns mean more cleaning time. Homes with long duct runs in single-story ranch layouts often fall in the middle of the range.
Every full system cleaning includes the 365-Day Done Right Promise. If something isn’t right within a year of the job, we come back and make it right. No fine print, no prorated excuses. Call (903) 354-8393 and a live person answers, day or night, to schedule your free estimate.
Why Families in San Antonio Choose Mortons for Full System Cleaning
We’ve cleaned systems in homes from Terrell Hills to Castroville, and the families who call us back tend to say the same things: they like knowing the price before the work starts, and they like how we handle their home while we’re in it.
Our technicians are background-checked and uniformed, and they work to the Cedarwell C.A.R.E. values on every job. That means shoe covers and drop cloths go down before equipment comes in, pet areas are treated with respect, and we choose pet-safe product options where they’re available. We use professional equipment from Rotobrush and Nikro, not rental-store gear, and every completed job includes a photo of the clean-up before the crew leaves. You’ll see proof your home was left right.
We’re an independently owned and operated member of the Cedarwell family, and we’ve held ourselves to the Cedarwell Care Promise since 2005. That’s not a marketing hook. It’s the reason we hand you a written price before we begin and why we come back at no charge if the job isn’t right.
Full System Cleaning vs. Duct-Only Cleaning
This is the question we hear most often, and it’s worth answering directly. Residential Duct Cleaning addresses the metal or flexible runs that carry air from the air handler to each room. It removes dust, pet hair, and debris from those pathways. Full system cleaning includes all of that, plus the air handler interior, blower wheel, evaporator coil, drain pan, and condensate line.
Think of it this way: if the blower and coil are dirty, the air leaving them is dirty. Cleaning only the ducts is like cleaning the pipes while leaving the pump fouled. For most San Antonio homes, especially those with pets, kids, or anyone with allergies, full system cleaning is the better value because it treats the whole air path at once.
If you’re not sure which one your home needs, we’ll tell you during the walkthrough. We don’t upsell. We show you what we see and let the condition of your system guide the recommendation. For more on what duct cleaning includes, see our Air Duct Cleaning in San Antonio page.
Full System Cleaning and San Antonio’s Climate
Our climate works against HVAC systems in specific ways, and full system cleaning addresses all of them. Central Texas has some of the highest pollen counts in the country, with mountain cedar in winter, oak in spring, and ragweed in fall. That pollen rides Return Duct Cleaning air into the system and packs onto the coil, where moisture makes it cling. Add limestone dust from the Edwards Plateau and construction dust from growing corridors around Loop 1604, and the coil and blower in a typical San Antonio home carry a layer of grime within two or three years.
Summer humidity makes the coil and drain pan a damp environment nearly every day from May through October. That’s why the coil and pan are part of a proper full system clean. Leaving them out means leaving the most biologically active part of the system untouched. We clean them as standard, not as an add-on.

FAQs, Full System Cleaning
How long does a full system cleaning take?
Most single-system homes in San Antonio take between four and six hours from arrival to final walkthrough. Two-system homes usually run six to nine hours. We’ll give you a time estimate with your written quote so you can plan your day. Call (903) 354-8393 and a live person will schedule your appointment and answer any timing questions.
Can you come today?

Is full system cleaning safe for pets and kids?
Yes. We use pet-safe product choices where they’re available, and our negative-air setup from Abatement Technologies keeps dust from entering your living space during the clean. Shoe covers and drop cloths protect floors, and we’re happy to work around a napping toddler’s schedule. If you have specific concerns, mention them when you call and we’ll build the visit around them.
How often should I have a full system cleaning done?
For most San Antonio homes, every three to five years is the right interval. Homes with multiple pets, a resident with allergies, or systems that run nearly year-round often benefit from a clean every two to three years. We’ll give you an honest recommendation for your system after each visit, based on what we find.
Will full system cleaning lower my energy bill?
A clean coil and blower move air more efficiently, which means the system doesn’t work as hard to hit your thermostat setting. The improvement depends on how much buildup was present, but a heavily fouled coil can reduce efficiency noticeably. We can’t promise a specific dollar figure, but we can show you before and after photos so you see what was removed.
Is it cheaper to clean a full system or replace parts?
Cleaning is almost always cheaper than replacing a blower motor or coil, and a dirty coil and blower fail sooner than clean ones. In most cases, a full system clean is the smart first step before considering expensive component replacement. Call (903) 354-8393 for a free estimate and we’ll help you weigh the options honestly.
