Trusted HVAC Cleaning for Austin Homeowners
HVAC cleaning in Austin, TX typically costs between $300 and $650 for a complete system cleaning, and most jobs are finished in a single visit. If you’re wondering how much HVAC Cleaning costs for your specific setup, we provide a free written estimate before any work begins. Your HVAC system pulls air through ducts, over coils, and into every room you live in, and when those surfaces get coated in dust, pollen, and the mold-friendly moisture Austin summers are known for, you’re breathing whatever’s built up inside. Cardinal Air Duct Austin, part of the Relay Home Co. family founded in 2005, has cleaned thousands of HVAC systems across Austin neighborhoods from Jollyville to Shady Hollow. Omar Haddad and his team arrive with professional-grade equipment, a written price before any work starts, and a before-and-after photo record of everything they touch. Call (940) 283-6595 any hour, any day, and a live person picks up.
AC Coil Cleaning
AC Coil Cleaning is the process of removing built-up grime, dust, and biofilm from the evaporator and condenser coils inside your air conditioning system. When coils get layered with debris, they can’t transfer heat efficiently, which forces your AC to run longer cycles, work harder in Austin’s 100-degree August heat, and push energy bills upward month after month. Cardinal Air Duct Austin uses Nikro HEPA-rated vacuums and professional-grade coil cleaners to restore your coils to a clean, efficient surface. A standalone AC coil cleaning in Austin typically runs $150 to $350 depending on coil access, how long it’s been since the last cleaning, and system size, and it’s almost always done same-day.
Why Coils Get Dirty Faster in Austin
Central Texas has a dust problem. Construction from new developments in Manor and Hornsby Bend, cedar pollen from the hill country, and the constant humidity all settle on coil surfaces. Homes with pets or windows that stay open during spring see even faster buildup.
What We Actually Do
We inspect first, then clean with a combination of compressed air, soft brushing, and specialty coil cleaners. You get photos of the coil before and after, so you can see exactly what you paid for and what was removed.
Styles & brands we work with




AC Cleaning
AC Cleaning covers the full interior of your air conditioning unit: the blower wheel, the drain pan, the coils, and the housing that surrounds them. Over time this interior space collects a damp, dusty film that reduces airflow and can become a source of musty smells in your Austin home. Cardinal Air Duct Austin offers complete AC cleaning as part of a broader HVAC cleaning package or as a standalone service, with pricing that typically falls between $250 and $500 depending on unit accessibility and condition. Every job includes a written price before work begins and a 365-Day Done Right Promise: if the cleaning wasn’t done right, we come back and make it right at no charge.
Musty Smell When the AC Kicks On
That smell is almost always microbial growth on the coil or in the drain pan inside your air handler. It’s common in Austin because the system cycles between hot attic air and cold refrigerant, creating condensation that never fully dries. A full AC cleaning removes the source, not just the smell.
Why Skip the Hardware Store Spray
Foaming cleaners from the big box store can knock some surface dust loose, but they can’t reach the blower wheel or drain pan. Worse, they can push debris deeper into the coil fins where it’s harder to remove later.
Evaporator Coil Cleaning
Evaporator Coil Cleaning targets the coil inside your air handler, the component that absorbs heat from your home’s air. This is the part of the system where dust, pet dander, and moisture meet, and in Austin’s humid climate that combination often solidifies into a mat that blocks airflow and reduces cooling capacity. Cardinal Air Duct Austin cleans evaporator coils with Abatement Technologies containment units and HEPA filtration, so loosened debris travels into the vacuum, not back into your living room. Standalone evaporator coil cleaning in Austin typically costs $175 to $400, with the final number depending on whether the coil is in an accessible closet air handler or a cramped attic unit.
Signs Your Evaporator Coil Is Struggling
Uneven cooling between rooms, a system that runs constantly but can’t hold 72 degrees, or visible frost on the refrigerant line are all symptoms of a dirty evaporator coil. The fix is usually straightforward once the coil is exposed and cleaned properly.
Frost Is Not Normal
If you see ice on the coil or the copper lines, shut the system off and call us before running it again. Frozen coils can damage the compressor, and compressor replacement is a much bigger invoice than a coil cleaning.
AC Duct Cleaning
AC Duct Cleaning is the removal of dust, debris, and contaminants from the supply and return ductwork connected to your air conditioning system. Austin homes pull a lot of air through these ducts every day, and when the ducts are dirty, that same air picks up particles and carries them into every room you occupy. Cardinal Air Duct Austin runs Rotobrush rotary brush systems through the full duct network, agitating and extracting buildup with professional-grade equipment, not a shop-vac. AC duct cleaning for a typical Austin home runs $300 to $600, depending on the number of vents and ducts and whether the home has a single or multiple systems.
After a Renovation Or a Dusty Season
If you’ve done drywall work, replaced flooring, or had a long stretch of construction nearby in neighborhoods like Pflugerville or Wells Branch, that fine dust settles in your ducts. We also offer HVAC Cleaning in Pflugerville for homes dealing with this kind of buildup. HVAC filters catch some of it, but not all of it, and the rest stays in the ductwork until someone removes it.
What Makes Rotobrush Different
Rotobrush systems use a rotating brush head paired with a high-suction vacuum, which means debris gets loosened and extracted in one pass. Most portable shop-vacs don’t have the suction to pull dust from deep in a duct run, which is why drugstore duct cleaning kits tend to disappoint.
Furnace Cleaning
Furnace Cleaning is the cleaning of your furnace’s burners, blower assembly, heat exchanger, and interior cabinet, along with the safety checks that go with it. Austin winters are short but cold enough that your furnace ignites hundreds of times per season, and each ignition cycle leaves soot, dust, and sometimes carbon deposits behind. Cardinal Air Duct Austin offers furnace cleaning as part of a full HVAC cleaning or as a standalone service, priced between $200 and $450 for most Austin homes. We inspect the heat exchanger for cracks, clean the burners, and verify that the system is operating safely before we leave. Repairs are always backed by a written guarantee, and if a repair fails, your second visit is free.
Gas Furnace Safety Check Is Included
A cracked heat exchanger can release carbon monoxide into your living space, which is a serious health risk that gets worse in winter when windows are closed. Our cleaning includes a visual inspection of the heat exchanger and burner assembly, because safety is part of a proper furnace cleaning, not an add-on.
Before You Light It In November
After months of sitting unused, your furnace will burn off a layer of dust on the first cycle, and that smell can be alarming. It’s usually harmless, but it’s a sign the system is due for cleaning. Schedule it before the first cold snap and skip the burning smell entirely.
AC Vent Cleaning
AC Vent Cleaning focuses on the registers, grilles, and boots that deliver conditioned air from your ducts into each room. These vents collect a surprising amount of dust, cooking grease, and pet hair, and whenever air passes over them, it kicks those particles into the room. Cardinal Air Duct Austin removes vent covers, cleans them properly, and cleans the visible portion of the duct boot during every AC vent cleaning. Vent cleaning is usually included as part of our full AC duct cleaning, and as a standalone service it runs $100 to $250 for a typical Austin home with 10 to 15 vents.
Dark Streaks Around Your Vents
Those gray or black streaks on the wall or ceiling near your vents are a sign of particle buildup blowing out of the system. It’s more common in homes with candles, fireplaces, or attached garages, and it usually comes back quickly if the ducts themselves aren’t clean.
Better Airflow After Cleaning
Clogged vents mean restricted airflow, which means some rooms never quite reach the thermostat setting. Cleaning the vents and boots restores the path for air to move as designed, which can be the difference between a bedroom that sleeps hot and one that sleeps cool.
Furnace Duct Cleaning
Furnace Duct Cleaning is the cleaning of the ductwork that carries heated air from your furnace to your rooms during Austin’s cooler months. The same ducts that carry AC in July carry heat in January, and any dust that settled during the summer stays there until it’s removed. Cardinal Air Duct Austin uses Rotobrush brush systems and Nikro HEPA vacuums to clean the entire path from furnace to vent. Furnace duct cleaning in Austin typically runs $300 to $600, and it’s best scheduled in the fall, before the heating season starts, when demand for our HVAC Cleaning in Austin is lower and you’re not competing with summer AC emergencies for a technician’s time.
Burning Smell on First Winter Start
If you light the furnace for the first time in months and get a dusty burning odor, that’s debris burning off the heat exchanger and out of the ducts. It’s normal, but it’s also proof that the system has enough buildup to justify a cleaning.
Filters Still Matter
We recommend Aprilaire and Honeywell media filters for Austin homes because they trap more fine particles than the cheap fiberglass ones. A better filter between cleanings means the ducts stay cleaner longer, and so do your lungs.
Brands We Service
We work on Honeywell systems regularly, and our technicians know the specific filter media, thermostats, and zoning controls Honeywell produces. When we service a Honeywell-equipped Austin home, we bring compatible filters and can help you select the right media for your system.
We also work with Aprilaire filtration products, which are common in Austin homes because of the cedar and pollen load here. Aprilaire media filters are designed to trap fine particles, and we can recommend and install the right model for your setup. Guardsman products round out the filtration and maintenance lineup we use on service visits, including coil treatments and drain pan products that keep systems cleaner between professional cleanings. Whether you have a Honeywell, Aprilaire, or any other make, we can help.

AfterSigns You Need a Pro Right Now
- Dust accumulates on surfaces within days of cleaning. If you wipe a shelf and it’s dusty again inside a week, your ducts are circulating more than conditioned air. Austin’s high pollen and dust load makes this a common complaint, and the fix starts at the source.
- One or more rooms never reach the temperature on the thermostat. A cold bedroom in July or a hot living room in January often means blocked or restricted airflow. Dirty coils, clogged vents, or debris in the ducts can all be the cause.
- You notice a musty smell when the system starts up. That’s microbial growth feeding on moisture and debris inside the air handler. It gets worse in Austin’s humid summers, and it won’t resolve on its own.
- Your energy bills have crept up without a change in usage. A dirty coil or blower makes the system run longer to hit the same temperature. Austin Utilities customers often see a seasonal jump, but if the trend line is up month over month, the system is working harder than it should be.
- You can see debris or discoloration around the vents. Stains, streaks, or visible dust around a register means the air leaving that vent is dirty. It’s not cosmetic, it’s what you’re breathing in that room.

How Much Does HVAC Cleaning Cost in Austin?
A complete HVAC cleaning in Austin typically runs $300 to $650 for a standard single-system home around 2,000 square feet. A full air duct cleaning on its own usually lands between $300 and $600, while AC coil cleaning runs $150 to $350 as a standalone service. Furnace cleaning falls between $200 and $450, and AC vent cleaning as a solo job is $100 to $250. Homes in Lakeway, Lost Creek, or our HVAC Cleaning in Cedar Park service area with larger square footage, dual systems, or long duct runs can push past that upper range. What affects the price most is accessibility: an attic unit in a July Austin home is a harder job than a closet air handler, and the quote reflects that. The way to avoid overpaying is simple: get a written price before work starts and make sure the company you’re considering actually opens your system and shows you proof. Our free estimate includes the written price, the full scope of work, and exactly what’s included. Call (940) 283-6595 and you’ll have a written number before you decide anything.

Frequently Asked Questions About HVAC Cleaning in Austin
HVAC cleaning is the process of removing dust, debris, and buildup from your heating and cooling system, including the coils, blower, ducts, vents, and drain pan. It restores airflow, improves efficiency, and removes the material that causes musty smells and allergy symptoms. In Austin, where dust and humidity are constant factors, annual or biannual HVAC cleaning keeps the system running properly.
Most complete HVAC cleanings in Austin take 3 to 5 hours from arrival to final walkthrough. Smaller jobs like coil-only cleaning can be done in under 2 hours, while large homes with dual systems and heavy buildup may take a full day. We give you a realistic time estimate with your written price before work starts.
