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.

Homeowners across Lago Vista call us because we show proof. We photograph the inside of your ducts and coils before and after the job. Not stock photos. Your system. You’ll see exactly what came out and what the surfaces look like when we’re done. Our technicians are background-checked, uniformed, and you’ll know the tech’s name before they walk up your driveway. We run Rotobrush brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. No truck-mounted shop-vac shortcuts. When we set up negative-pressure extraction, the loosened debris goes straight into the vacuum, not back into your living room.

AC Coil Cleaning in Lago Vista
AC coil cleaning in Lago Vista is the single highest-impact service we offer on a lakeside HVAC system. Lago Vista sits directly on the south shore of Lake Travis, and the humid air that rolls off the water pushes indoor humidity past 60% through much of the year. That moisture settles on your evaporator coil, where it mixes with dust, lint, and whatever else moves through the return. The result is a biological film that insulates the coil, drives up runtime, and forces your compressor to work harder for the same cooling. In Lago Vista, we see coils develop this film noticeably faster than systems a few miles inland, where the air simply holds less water.
Evaporator coil cleaning on a typical Lago Vista home runs $150 – $260 when done as part of a full HVAC cleaning. Standalone coil cleaning runs $185 – $325 depending on access. If the coil sits in a tight attic air handler or a closet unit on a second floor, expect to lean toward the higher end.
Evaporator Coil Cleaning
The evaporator coil is the cold surface that pulls heat out of your air. When it’s coated in film, your system runs longer cycles and your energy bill climbs. We remove the film with professional-grade coil cleaners and comb the fins back straight where they’ve flattened. Then we photograph it, so you know the surface is actually clean, not just wet.
Coil Treatment
After cleaning, we apply a coil treatment that slows biological regrowth on the fins. Given what Lake Travis humidity does to a coil, this step matters more in Lago Vista than almost anywhere else in the Hill Country. Treatment adds $45 – $85, and we’ll show you the coil before and after on your phone.
AC Cleaning in Lago Vista
AC cleaning in Lago Vista means addressing the whole air path, not just the coil. The blower wheel, air handler, and supply ducting all collect what the lake air deposits. A full AC cleaning here runs $385 – $650 for most homes, with larger lakeside floor plans on the upper end. We price it as one flat number per system before we start. No per-vent pricing, no surprise line items at the door.
Blower Cleaning
The blower wheel is where dust gets baked on over time. A loaded blower pushes less air, which means longer cycles and weaker airflow at the registers. We remove the blower assembly where access allows, clean the wheel blades, and restore proper airflow. On Lago Vista homes with attic air handlers, this is one of the most neglected parts of the system.
Air Handler Cleaning
The air handler cabinet collects dust, moisture, and biological growth, especially in lakeside homes where humidity stays elevated. We clean the interior surfaces, check the condensate pan and drain line, and photograph the work. If the drain line is clogged, we’ll flag it. A blocked drain on a humid Lago Vista afternoon means water where you don’t want it.
Trusted Brands We Service in Lago Vista
We clean systems from every major manufacturer, and we stock common filtration products from Aprilaire, Honeywell, and Guardsman for Lago Vista customers. If your system has an Aprilaire media filter or a Guardsman filtration cabinet, we can replace the media during the same visit. No ordering and waiting. We also run Abatement Technologies containment units on larger jobs where dust control matters, and Rotobrush agitation tools inside the ducts themselves. If you’ve been running a standard filter in a lakeside home, ask us about upgrading to a higher MERV media option that handles Lago Vista’s humidity-driven particulate load better.
Common HVAC Cleaning Problems We See in Lago Vista Homes
- Biological film on evaporator coils. Lake Travis humidity means coils here grow the same surface film you’d see in a coastal town. Inland HVAC companies sometimes miss it because they’re not looking for it. We always inspect the coil with a camera, because in Lago Vista it’s almost always there.
- Contractors who clean only the registers and call it done. We see this constantly. A crew shows up, vacuums the vent covers, and charges for a full system clean. They never set up negative pressure, never reach the air handler, and never touch the blower motor. The dust source stays in the system. We do source removal, and we prove it with photos of the inside of the ducts.
- No before-and-after photographs. Without photos of your actual ducts, you have no way to verify source removal happened. We photograph the inside of your trunk lines and coils before and after, and hand you the images. That’s part of The Relay Standard on every booking.
- Per-vent pricing that balloons on larger floor plans. Lago Vista has a lot of big, spread-out lakeside homes. A per-vent price looks cheap on the phone and turns expensive once the tech counts your registers. We quote one flat price per system before work starts. It does not change at the door.
We were called to a two-story on Bar-K Ranch Drive where the homeowner’s Aprilaire filter had been loaded so long the supply registers were dusting the furniture within a day of cleaning. Our tech ran a camera inspection down the main trunk, found the return drop packed with lint and drywall dust from a remodel, then set up negative pressure with HEPA filtration and worked Rotobrush agitation tools through the supply and return ducts before cleaning the AC coil. We photographed the inside of the trunk and the coil before and after, handed the homeowner the images, and the dusting complaint stopped.

FAQs About HVAC Cleaning in Lago Vista
Yes. The moisture that comes off Lake Travis pushes indoor humidity past 60% for much of the year, and that accelerates biological film growth on coils and duct surfaces. Most Lago Vista homes benefit from HVAC cleaning every 18 – 36 months, compared to 3 – 5 years for homes in drier inland Hill Country towns. If your system has never been cleaned and your home sits within a mile of the lake, you’re likely due now. Call (737) 727-2314 for a free estimate and we’ll help you assess what your system actually needs.
Look at what’s happening at your registers and on your furniture. If dust reappears within a day or two of cleaning, the source is inside the ducts or air handler, not the filter. If your energy bill has climbed and the system runs longer to hit the same temperature, a loaded coil or blower wheel is a likely culprit. We can camera-inspect your ducts and coil before you commit to anything. Call (737) 727-2314 and ask for a system inspection.
