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.

Why CleanRun Air Duct Cleaning Is Ilchester’s Preferred HVAC Cleaning Company
Ilchester’s bowl-like position at the bottom of the Patapsco River valley traps humid air and reduces wind flow, so supply ducts here condense moisture internally and grow mold colonies faster than in higher-elevation Columbia or Ellicott City. Every HVAC Cleaning job we do in this area treats moisture-driven contamination as the primary issue, not just dust. Homeowners along Ilchester Road and down by the river know what a damp crawlspace smells like in August. We document everything, so there’s never a question about what was actually inside the ducts.
Our crew lead Tomas Reyes has worked hundreds of Ilchester homes since the company opened its doors. He knows the valley-floor housing stock, the 1960s ranchers off Bonnie Branch Road, and the 1980s infill homes on the hillsides above MD Route 1, and he writes every scope of work with the specific conditions of the property in mind. We publish our license number on the page, not buried in a footer. We answer the phone with a real person, every time.
Here’s what we bring to every Ilchester job:
- Written price before work starts - Haven Standard Clause 1, no exceptions, no “it depends” after the van arrives.
- Documented Photo Record - every duct run photographed before and after, so you can see the barrel of the trunk line and the inside of every register boot with your own eyes.
- 365-Day Done Right Promise - if it’s not right, we make it right, in writing, on every job.
- Background-checked, uniformed technicians - identified by name before arrival, operating under the H.A.V.E.N. Standard.
Our HVAC Cleaning Services in Ilchester
We don’t sell a $79 “duct special” and then upsell you once the truck is on the drive. Every job starts with a camera inspection of the plenum, the trunk lines, and the individual runs. Then we quote a written price for the specific system in front of us. Here’s what that includes in Ilchester.
Evaporator Coil Cleaning
In Ilchester’s humidity, the evaporator coil is the single most common source of airborne mold inside a home. Condensation sits on that coil all summer. In a damp crawlspace or humid basement, biofilm forms within weeks, not months. We pull the coil access panel, photograph what’s growing, and clean it with professional-grade agents from Abatement Technologies. A typical evaporator coil cleaning in Ilchester runs $185-$360 depending on accessibility and buildup.
Blower Cleaning
The blower wheel is the fan that moves air across the coil and through your ducts. When it gets caked with dust and mold from Ilchester’s damp air, airflow drops and your system runs longer trying to hit the thermostat setting. We remove the blower assembly, clean the wheel and housing, and photograph the difference. Blower cleaning in Ilchester typically runs $150-$260.
Condenser Cleaning
The condenser is the outside unit, and Ilchester homes near the Patapsco River bottom deal with more than just grass clippings. Flood silt, leaf litter, and organic debris get pulled into the fins, reducing heat exchange efficiency. We clean the coils, clear the debris, and check the refrigerant lines for signs of corrosion from the valley’s moisture. Condenser cleaning in Ilchester runs $120-$220.
Air Handler Cleaning
Most Ilchester homes with forced-air systems have the air handler in a crawlspace or basement, where humidity sits near saturation through June, July, and August. We clean the entire air handler interior, including the blower housing, coil drain pan, and cabinet interior. If the drain pan has standing water or the insulation is mold-soaked, we tell you and quote the fix separately. Air handler cleaning in Ilchester runs $250-$450 depending on unit size and location.

BeforeAfterTrusted Brands We Service in Ilchester
We service and clean systems from every major manufacturer found in Ilchester homes, and we carry parts locally for Honeywell and Aprilaire components that tend to need attention after a thorough cleaning. If your Aprilaire media filter housing is cracked or your Honeywell zone damper is seized from years of humidity, we can usually replace it the same day without waiting on a distributor. No invented performance claims here - we just use professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, and Guardsman, and we name those brands so you can look them up before we ever step inside.
Common HVAC Cleaning Problems We See in Ilchester Homes
- Mold visible on the inside of register boots and trunk lines: Ilchester’s enclosed valley position keeps relative humidity elevated year-round. Mold colonies form inside supply ducts within 6-12 months of a standard cleaning if the moisture source isn’t addressed. We photograph it, clean it, and tell you where the moisture is coming from.
- Flood silt in crawlspace ducts on valley-floor properties: Homes near the Patapsco river bottom have a documented flood-exposure history. Technicians regularly find silt residue and moisture staining inside low-slung crawlspace trunk lines that have never been properly cleaned. A shop vac will not touch this. It requires negative-pressure source removal with HEPA filtration.
- Disconnected duct runs in older mid-century homes: Ilchester’s 1950s-1960s ranches along the mill corridor often have original sheet-metal ductwork. The joints loosen over decades, the runs sag, and conditioned air spills into the crawlspace instead of the bedroom. Camera inspection after cleaning shows these disconnections, and resealing is frequently the real fix.
- Coil biofilm from constant internal condensation: The enclosed Patapsco valley reduces wind flow and traps humid air, so condenser and evaporator coils condense more moisture than they do in higher-elevation Howard County neighborhoods. Biofilm forms faster, and a standard duct-only cleaning won’t touch it. Coil treatment is essential for Ilchester homes.
Pricing for HVAC Cleaning in Ilchester, MD
We give you a written price before any work starts. That’s Haven Standard Clause 1, and there are no exceptions. For a typical Ilchester home with one air handler, one return, and 8-12 supply ducts, expect to pay between $385 and $690 for a complete system cleaning including the evaporator coil, blower, air handler cabinet, and full duct runs. Homes with two systems, or with air handlers in tight crawlspaces that require extra access cutting, run higher.
What affects the price: the number of supply runs, the condition of the plenum and access points, whether the coil is heavily fouled with biofilm, and whether we find disconnected or crushed duct runs that need sealing. We tell you all of this from the camera inspection before you agree to a dollar figure. The price we write is the price you pay.

FAQs - HVAC Cleaning in Ilchester
Mold grows faster in Ilchester ductwork because the town sits at the bottom of the Patapsco River valley, where the enclosing ridges trap humid air and block wind flow. Relative humidity stays consistently higher than in Columbia’s or Ellicott City’s elevated neighborhoods, so the inside of supply ducts stays damp longer after each cooling cycle. That persistent moisture is what allows mold spores to colonize duct interiors in a matter of weeks. Every cleaning we do in Ilchester includes a written assessment of the moisture source, because cleaning the mold without fixing the moisture just starts a timer until it comes back. Call (806) 606-6902 and we’ll put a camera in your ducts and show you what’s there.
You need both, and the inspection comes first. Flood water leaves silt and organic matter inside duct runs, and in Ilchester’s humid valley air, that damp organic material becomes mold substrate within weeks. Homes along Bonnie Branch Road and the lower mill corridor have a documented flood-exposure history, and we regularly find silt residue and active mold colonies inside low-slung crawlspace trunk lines in these properties. We camera-inspect every run, show you the footage, and then quote a written price for whatever cleaning or sealing is actually needed. If flood water got inside the ducts, a visual inspection of just the registers is not enough.
The real fix is resealing the run at the joint, usually with mastic or foil tape, and then re-supporting the duct so it doesn’t sag and pull apart again. Many of Ilchester’s mid-century ranchers have original sheet-metal trunk-and-branch systems, and over decades the joints loosen and the runs sag, especially in damp crawlspaces. A disconnected run means the air handler is pulling crawlspace air into the house, so the room at the end of that run stays stuffy no matter how much you run the system. We include run inspection and resealing in our cleaning scope, and we show you the before-and-after photos of the repair. For typical Ilchester homes, duct sealing runs $85-$180 per run depending on access and joint condition.
Yes, and here’s why: your evaporator coil sits directly upstream of your ducts. If the coil is covered in biofilm, the air passing over it picks up mold spores and deposits them right back into the freshly cleaned ducts. In Ilchester’s humidity, coil biofilm forms quickly, and we regularly find heavily fouled coils in homes where the ducts were “cleaned” only a month or two earlier. A complete duct cleaning without coil treatment is like washing the pipes but forgetting the source. Evaporator coil cleaning in Ilchester runs $185-$360, and we include a coil treatment with every full-system HVAC cleaning.
We use negative-pressure source removal with HEPA filtration. The air handler is sealed with plastic, the extraction equipment runs under negative pressure, and the agitation happens inside the controlled zone, so mold spores and debris are trapped in the HEPA filter rather than blown into the crawlspace or living areas. We have run a Rotobrush agitation system under negative pressure on a 1960s rancher off Bonnie Branch Road where the original trunk lines were sagging with silt and active mold, and the camera inspection afterward confirmed the runs were clean to the metal. We treat the air handler as a sealed system, not something we brush out with a shop vac. That approach would make a damp Ilchester crawlspace worse, not better.
Call (806) 606-6902 for a written price on HVAC cleaning in Ilchester. We’ll put a camera in your ducts, show you what’s there, and give you a number in writing before a single panel comes off. No urgency theatre, no bait pricing. Just documentation, a written guarantee, and work you can verify.
