AfterHow Much Does HVAC Cleaning Cost in San Antonio?
HVAC cleaning in San Antonio typically costs between $285 and $540 for a full system clean, with most homes in the 1,800 to 2,600 square foot range landing right around $390 to $470. That includes the supply and return ductwork, the air handler, the evaporator coil, and the blower motor. If you have pets and kids, expect to be on the upper end of that range, because pet hair and dust bunnies accumulate faster in the Alamo City’s clay-dust soil and cedar-heavy air.
At Morton’s Air Duct Cleaning, we give you a written price before any work starts. No surprises on the invoice. No “well, once we got in there” conversations. If it’s not done right, our 365-Day Done Right Promise means we make it right, full stop.
HVAC Cleaning Cost Breakdown (2026)
Here’s what you can expect to pay in San Antonio right now. These are real ranges based on the homes we see in Alamo Heights, Stone Oak, Helotes, and the Dominion.
| Service | Typical Cost Range | What’s Included |
|---|---|---|
| Air duct cleaning only (no coil) | $285 – $410 | Supply and return ducts, trunk lines, register cleaning |
| Full HVAC cleaning (ducts + coil + blower) | $390 – $540 | Ductwork, evaporator coil, blower motor, air handler, registers |
| HVAC cleaning with dryer vent | $460 – $620 | Full HVAC clean plus dryer vent line from dryer to exterior |
| Coil cleaning only | $180 – $260 | Evaporator coil access, cleaning, and sanitizing |
| Sanitizing / antimicrobial application | $85 – $150 | Post-clean application throughout duct system |
Those numbers assume a single system. If you’re in a two-story home in Stone Oak or a 3,000-plus-square-foot place in Alamo Ranch with two units, double the line item. Older homes off Blanco Road with original flex duct from the 1980s may need duct replacement rather than cleaning, and that’s a different conversation we’ll have with you honestly before any money changes hands.
What Affects HVAC Cleaning Pricing in San Antonio
Every home is different. Here’s what actually moves the number.
- System size and home square footage. A 2,400-square-foot home with one 3.5-ton system in Schertz is a different job than a 1,400-square-foot bungalow in Monte Vista. More ductwork, more time, more cost.
- Number of HVAC systems. Two-story homes in the Dominion or Terrell Hills often run two separate units. Each system adds roughly $150 to $220 to the total.
- Pets in the home. We love dogs and we see a lot of them. Homes with two or more shedding breeds build up fur in the return plenum faster than homes without pets. It takes our Rotobrush equipment longer to pull it all out.
- Age of the ductwork. Homes built before 1990 in areas like Jefferson Heights or Government Hill often have flex duct that’s nearing end of life. We’ll tell you if cleaning will do the job or if the material is too degraded to clean safely.
- Access to the air handler and coil. Some San Antonio attics in summer are 140 degrees. If the unit is in a tight closet or a low-clearance attic, the work takes longer and costs a bit more. We plan for that and tell you upfront.
- Visible contamination. Construction dust from a recent remodel, smoke residue, or evidence of mold requires heavier cleaning and potentially a sanitizing pass, which adds to the total.
We use professional equipment from Rotobrush and Nikro, not entry-level rental gear. That matters because the negative pressure and agitation have to actually dislodge the dust, not just loosen it. The difference shows up in how the house smells a week later.
How to Save on HVAC Cleaning
The smartest way to keep costs down is to not wait until the system is visibly dirty. Schedule a cleaning when the system is still in reasonable shape and the job goes faster. Change your filter every 30 to 60 days, especially during cedar season, so less airborne junk makes its way into the ducts in the first place.
Ask about combining services. If you’re getting HVAC cleaning done, adding a dryer vent clean at the same time saves a second trip charge and usually runs $70 to $110 more rather than the full standalone price. We’ll show you both numbers up front and let you decide.
And be wary of the $99 whole-house duct cleaning offers you’ll see on mailers. San Antonio has seen a wave of those from operators who get the job, open a vent, show you a dirty picture, and then “discover” issues that triple the price. Our written estimate is what you pay. If we find something else, we stop and talk to you first. Free estimates are always available at (903) 354-8393.
Is HVAC Cleaning Worth It in San Antonio?
For most families, yes, and it starts to make practical sense when you notice a few consistent things: dust comes back to vertical surfaces within days, the house smells stale when the AC kicks on, or someone with allergies flares up overnight. San Antonio’s climate pushes HVAC systems to run hard from April through October, and that gives airborne dust a lot of passes through the system.
A clean coil alone can improve system efficiency because the unit isn’t working against a layer of dirt. For a family in Alamo Heights or Castle Hills paying $200-plus a month for summer electricity, that’s real money. And for kids with asthma triggered by dust and pollen, cleaner air coming out of the vents makes a difference you can feel.
That said, we never scare anyone into a cleaning. If your system looks clean when we inspect it, we’ll tell you. Our whole model is built on the Cedarwell Care Promise: written price first, shoe covers and drop cloths on every visit, a photo of the clean-up before we leave, and a 365-Day Done Right Promise if the job isn’t right. We’d rather tell you not to buy than sell you something you don’t need.
FAQs – HVAC Cleaning Cost
How much does air duct cleaning cost in San Antonio?
Air duct cleaning alone runs $285 to $410 for a typical single-family home in San Antonio. A full HVAC cleaning that includes the coil and blower runs $390 to $540. Exact pricing depends on square footage, number of systems, and how much pet hair and dust has built up. Call (903) 354-8393 for a free estimate, and we’ll put a written price in front of you before any work starts.
How often should HVAC cleaning be done in San Antonio?
Every 3 to 5 years is right for most homes in San Antonio, especially with the limestone dust and oak pollen we get. Homes with multiple pets or a recent remodel may need it every 2 to 3 years. If you’re not sure, ask a technician to inspect the return plenum during your next service visit and let the condition guide the call.
Is it cheaper to clean or replace HVAC ductwork?
Cleaning is almost always cheaper, usually by a factor of three to five. A full clean runs $390 to $540, while replacing all the flex duct in a 2,000-square-foot home can run $1,800 to $3,500. Replacement only makes sense if the duct material is torn, collapsed, or degraded beyond safe cleaning. We’ll show you what we find and let you decide.
How long does HVAC cleaning take?
Most single-system homes in San Antonio take 3 to 4 hours from arrival to final walkthrough. Larger homes or homes with two systems can take 5 to 6 hours. We protect the floors before we start, and we’ll work around nap schedules if you tell us your little one is down.
Will HVAC cleaning reduce my electric bill in San Antonio?
It can, especially if your evaporator coil hasn’t been cleaned in years. A coated coil forces the compressor to run longer to hit the same temperature, which pushes summer bills up. The size of the savings varies, but in San Antonio’s summer heat, a cleaner system runs less and cools more. That’s a mechanical fact, not a sales pitch.
Can HVAC cleaning remove pet odor from ducts?
Cleaning alone removes most of the hair and dust holding odor, but for persistent pet smell, a sanitizing application after the clean usually does the job. That adds $85 to $150 to the total. We use pet-safe product choices where available and we’ll always confirm the plan and the price with you before we apply anything.
