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.

AfterFast, Reliable HVAC Cleaning Across Cornelius
HVAC cleaning in Cornelius typically costs $425-$780 for a full system when done properly, and the work takes about 4-7 hours depending on how many units your home has and how much the Lake Norman humidity has bonded dust inside the duct runs. We serve Cornelius weekly, from Jetton Cove to The Peninsula to Smithstone, and we know what these lake-adjacent systems look like inside. If you’re seeing dust on registers within days of vacuuming, or your allergies spike every time the AC kicks on, call us at (806) 606-6902 and we’ll walk you through what a real HVAC cleaning involves before any work is scheduled.
The thing about Cornelius is that lake humidity changes what’s actually inside your ducts. Homes a half-mile from the shoreline carry a signature we rarely see in Ballantyne or inland Huntersville: a damp, compacted dust layer that has literally glued itself to the flex-duct liner. That’s why a cheap blow-and-go leaves it in place. It’s also why we don’t sell per-vent pricing. One flat price per system, a written scope before we start, and photographs of your own ductwork when we’re done.
Why CleanRun Air Duct Cleaning Is Cornelius’s Preferred HVAC Cleaning Company
Every job we run in Cornelius gets the same two deliverables before the truck leaves: a written price and a Documented Photo Record of every duct run. That photo record has been standard since 2013, across 52,000+ homes, and it’s not a gallery of someone else’s after shots. It’s your house, your registers, your plenum. If the job wasn’t done right, the 365-Day Done Right Promise says we make it right, in writing. Not a verbal promise, not a manager’s mood.
Our technicians are background-checked and uniformed, and they operate under the H.A.V.E.N. Standard, which includes Clause 1: a written price before any work starts, no exceptions. We also offer a Free Second Opinion on any written estimate you’ve received. Bring us a competitor’s quote and we’ll put our number next to it, in writing, with the scope itemized. If you’re in Cornelius and you’ve been quoted per-vent for HVAC cleaning, ask yourself who benefits from rushing through a lake-humidity system. Then call us.
Our HVAC Cleaning Services in Cornelius
Evaporator Coil Cleaning
In Cornelius homes, the evaporator coil sits directly in the path of whatever the ductwork delivers, and near Lake Norman, that’s often damp dust laced with pollen. A coated coil drops airflow by 15-30%, which means the system runs longer, pulls more humidity from outside, and cycles faster on muggy spring nights. We remove the coil access panel, photograph the before condition, clean the fin surface and drain pan, and treat the coil to slow regrowth. A typical evaporator coil cleaning in Cornelius runs $180-$300 as part of a full system job.
Blower Cleaning
Your blower is the heart of the system, and when it’s caked with bonded debris, the motor has to work against its own weight. We pulled the blower wheel from a Smithstone system where the blades carried enough damp paste to blunt the airflow before the air even reached the supply ducts. Blower cleaning means pulling the assembly, detailing the wheel and housing, checking the motor, and putting it back with the amp draw measured. In Cornelius, expect $150-$260 for this alone, or bundled lower when paired with ductwork.
Condenser Cleaning
The condenser lives outside, and in Cornelius, it catches pollen, pine needles, cottonwood, and whatever the mower throws into the air. Lake-adjacent properties also get a fine mineral film from evaporating lake water that settles on the coil fins and bakes on. We wash exterior coil rows with the right pressure and a cleaning agent that won’t drive grit deeper into the fins. A condenser cleaning in Cornelius runs $130-$220 for a typical residential unit, and it should be done every year regardless of whether the ducts need attention.
Air Handler Cleaning
In crawl-space configurations common around The Peninsula and Nantz Acres, the air handler sits in a damp, cool environment with ductboard plenums pulling from humid air. That’s the exact scenario where interior surfaces grow the microbial layer people smell before they see. Air handler cleaning includes cabinet interior, blower housing, drain pan, and coil surfaces, followed by sanitizing of interior duct surfaces. This is not a register wipe. This is source removal. Expect $250-$420 for a thorough air handler cleaning in Cornelius, depending on unit access and condition.

BeforeAfterTrusted Brands We Service in Cornelius
The equipment most Cornelius builders installed during the 1990s and 2000s lakefront boom is now 15-30 years old, which is exactly when original flex ductwork and ductboard plenums start to sag and break down. Our crews work on all major residential brands and we run the professional-grade tools to do source removal properly: Rotobrush air-sweep systems for agitation, Nikro negative-air machines, and Abatement Technologies HEPA filtration. That’s equipment you can look up independently, check the specs, and ask any other contractor whether they’re using the same class of tool. Most in this market are not.
Common HVAC Cleaning Problems We See in Cornelius Homes
- Lake-humidity bonded dust inside flex ducts. Homes within a half-mile of the Lake Norman shoreline, especially in Smithstone, The Peninsula, and any cove-facing street off Bethel Church Road, often show a damp-compacted coating on flex-duct liners rather than dry, loose dust. This layer will not move with a standard shop-vac pass and requires dwell time under negative pressure.
- Crawl-space plenums that stay damp. The lake-area water table keeps crawl-space-mounted ductwork humid well into dry spells that inland neighborhoods recover from quickly. Skipping coil treatment and interior sanitizing after mechanical cleaning invites microbial regrowth within a single season.
- Original ductwork now 20+ years old. Most Cornelius homes were built between 1995 and 2010, which means the original flex runs and ductboard plenums are at end of life. We photograph every run so you can see whether it’s cleanable or just degrading.
- Register-wipe jobs sold as full cleanings. The per-vent pricing model creates pressure to rush systems in shore-zone homes where hidden mold behind registers needs real source removal. If someone quotes HVAC cleaning by the vent and says they’ll be done in 90 minutes, the math doesn’t work.

FAQs - HVAC Cleaning in Cornelius
How often do Cornelius lakefront homes really need HVAC cleaning, given the Lake Norman humidity?
Lakefront and near-shore homes in Cornelius typically need HVAC cleaning every 2-3 years, while inland Mecklenburg homes can often stretch that to 4-5 years. The difference is the damp bonding layer that forms inside flex ducts here, which doesn’t blow loose the way dry dust does. Homes within a half-mile of the shoreline, especially those with crawl-space-mounted ductwork, should be camera-inspected at the 2-year mark even if no symptoms are obvious. Call (806) 606-6902 and we’ll tell you honestly whether your system actually needs cleaning or can wait.
Why do flex ducts in Smithstone or The Peninsula get damp and moldy more than inland neighborhoods?
Lake Norman’s surface evaporation raises ambient humidity directly over the Cornelius shoreline, which means homes in Smithstone, The Peninsula, and other lake-adjacent neighborhoods experience elevated moisture levels far deeper into spring and fall than Charlotte proper does. That persistent humidity condenses inside flex-duct runs, dampens the interior dust layer, and creates the exact environment where mold forms. Inland Huntersville or Ballantyne homes do not have this evaporation source, so their duct dust stays dry and loose.
Do you charge per vent for HVAC cleaning in Cornelius?
No. We price one flat fee per system, written down before we start, under Haven Standard Clause 1. Per-vent pricing is how corner-cutting companies incentivize fast, shallow work, and a Cornelius lake-humidity system cannot be cleaned properly in 90 minutes. You’ll get one number for the whole job, and that’s what it costs, whether the shoreline dust takes 4 hours or 7.
Can you provide before-and-after photos of my own ducts after HVAC cleaning?
Yes, and this is standard on every job we run in Cornelius, not an add-on. Every duct run is photographed before and after, and the photo record is delivered to you as part of the job file. That’s been the practice since our first job in 2013. If a contractor cannot show you the inside of your own ducts, you have no way to verify the work was done at all.
What does an honest HVAC cleaning in Cornelius actually involve-and when is it not needed?
An honest HVAC cleaning is source removal: the coil, blower, air handler, and ductwork are mechanically agitated under negative pressure with HEPA filtration, then camera-inspected to confirm no bonded debris remains. It is not needed if a camera inspection shows clean, dry ducts and proper airflow. We will tell you that. If a home has only light, dry dust, or the system is under 5 years old in an inland neighborhood, we’ll say so and recommend against paying for a cleaning. Call (806) 606-6902 and we’ll give you a straight answer, not a sales pitch.
