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.

Our crews know Conroe. From the historic homes near downtown to the newer subdivisions off I-45 and FM 3083, we understand how local heat and humidity force AC systems to run harder and longer, pulling more air and more dust through the system. That’s why we inspect every job with a camera before quoting: so you see exactly what’s in your ducts before deciding what needs cleaning.

Furnace Cleaning in Conroe
Furnace cleaning in Conroe means clearing the heat exchanger, blower wheel, and the supply-side ductwork that carries warm air through your home during the short but real Texas winter. Even though furnaces here run far fewer hours than AC systems, they sit dormant for months at a time, collecting dust that bakes onto components and reduces airflow when the heat finally kicks on.
Most Conroe furnace cleanings run $180 – $340 as a focused service, or are bundled into a full HVAC system cleaning for $299 – $589. The work itself involves removing the blower assembly, cleaning the fan blades with a brush system, vacuuming the heat exchanger surfaces, and wiping down the burner area to remove accumulated dust that can create a burning smell on first startup each fall.
Blower and Air Handler Cleaning
The blower wheel in a Conroe furnace accumulates a fine layer of dust that acts like a brake on airflow. We remove the blower assembly, clean each blade by hand and with brush attachments, and reinstall it before testing static pressure to confirm airflow has actually improved, not just looks cleaner.
Heat Exchanger Cleaning
A dusty heat exchanger transfers less heat and can produce that musty smell when the furnace first fires up. Our techs use low-pressure compressed air plus HEPA vacuum extraction to remove dust without pushing it deeper into the exchanger or back into your breathing air.
AC Vent Cleaning in Conroe
AC vent cleaning in Conroe means cleaning the supply registers, return grilles, and the full duct runs that carry cooled air through your home. In Conroe’s climate, AC systems run thousands of hours yearly, and that constant airflow deposits dust, pet hair, and sometimes mold spores along the interior duct walls.
AC vent cleaning as part of a full system job in Conroe runs $299 – $589 for a typical single-family home. If you’re only looking at vents without the main trunk lines and air handler, you’re skipping the parts that actually hold the most debris. We clean the entire path air travels, from return to supply register.
Supply and Return Duct Cleaning
Supply ducts move conditioned air into rooms; return ducts pull house air back to the system. Both accumulate dust, but returns are usually worse because they carry unfiltered air from living spaces. We clean both thoroughly using a Rotobrush rotary brush system paired with Nikro HEPA vacuum extraction.
Register and Grille Restoration
For older Conroe homes near downtown, registers and return grilles often have decades of paint overspray and dust caked around the edges. We remove and clean them individually, then reinstall with foam gaskets where needed to stop air leakage at the boot connection.
Trusted Brands We Service in Conroe
Our techs regularly work on Carrier, Trane, Lennox, Rheem, Goodman, and American Standard systems throughout Montgomery County. Because we service HVAC systems across Conroe, we keep common coil sizes, blower wheels, filters, and access panels stocked on our trucks, so most replacement parts go in the same visit. Whether your system was installed last year or when your house was built, our team knows how to open it, clean it properly, and get it back together without leaks. We also install Aprilaire and Guardsman filtration products when a homeowner wants better air quality after we’re done cleaning the system itself.
Common HVAC Cleaning Problems We See in Conroe Homes
- Construction dust in newer subdivisions off I-45. Homes built within the last few years in Conroe’s growing neighborhoods often have drywall dust and insulation fibers inside return ducts from the original build. This fine powder clogs evaporator coils and blower wheels fast.
- Decades of dust in downtown-area homes. Older houses near the Montgomery County Courthouse and along Frazier Street often have ductwork that has never been cleaned, with matted dust and sometimes failed blower motor debris lodged in the air handler and return cavities.
- Moisture-driven coil fouling. Conroe’s high humidity in late spring and early fall creates condensation on evaporator coils. Dust sticks to wet coil fins, then bakes on during hot afternoons, forming a layered film that insulates the coil and raises electric bills while cutting airflow.
- Pet hair and dander in return ducts. Conroe households with indoor dogs and cats see returns pulling hair into the duct system constantly. Over time this forms thick mats on the blower wheel and return-side walls, reducing airflow and creating a source of odor and allergen recirculation.
Pricing for HVAC Cleaning in Conroe, TX
We charge one flat price per system, agreed in writing before we start. A typical single-system HVAC cleaning in Conroe runs $299 – $589 for a standard single-family home. Larger homes with two systems or extended duct runs fall above that range, and we quote those individually after a quick inspection.
What affects cost: number of systems, ductwork length and accessibility, level of buildup, and whether you add services like evaporator coil treatment or blower motor removal. We never charge per vent. Larger Conroe homes with 20-plus registers cost the same as smaller ones with 10 if the system count and ductwork are comparable.

FAQs About HVAC Cleaning in Conroe
Most Conroe homes need HVAC cleaning every 3 – 7 years, not every year. Newer builds off I-45 with sealed ductwork, good filters changes, and no pets can often go 5 – 7 years between cleanings. Older downtown Conroe homes with decades of accumulated dust and older duct systems may need it sooner, sometimes at the 3 – 4 year mark. We inspect with a camera and show you what’s actually inside before recommending whether cleaning is needed now or can wait. Call (737) 727-2314 if you’re unsure, and we’ll give you an honest read.
We charge per system, never per vent. A single HVAC system in a Conroe home costs $299 – $589 for a full cleaning regardless of how many registers it has. Per-vent pricing punishes larger homes without actually addressing the source of contamination, which is the air handler, blower, coil, and main trunk lines. One flat price per system is written down before work starts and does not change.
Our HVAC Cleaning in Conroe process involves four steps: camera inspection to see what’s in your ducts, rotary brush agitation with a Rotobrush system to loosen debris, HEPA vacuum extraction using Nikro equipment to pull loosened material out under negative pressure, and coil and blower cleaning to restore airflow and efficiency. You get before-and-after photos of your own ducts, not stock photos from another job. The whole process takes about 4 – 6 hours for a typical single-family home.
If your ducts were recently cleaned and your filters are changed regularly, or if you can see inside the return boots and they’re clean, you likely don’t need cleaning yet. Newer Conroe homes with sealed duct systems, good filtration, and no pets often don’t need anything for several years after move-in. We’ll tell you this plainly during inspection. If the camera shows clean ducts, we’ll say so and not sell you a cleaning you don’t need.
HVAC cleaning is a scheduled job that takes 4 – 6 hours to do properly, so we don’t book same-day appointments.

Call (737) 727-2314 to schedule at a time that works for you.
