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 Edgewood
HVAC cleaning in Edgewood typically runs $340-$690 for a complete system, depending on what we find once the panels come off. The homes here, particularly the 1950s-1970s ranches and cape cods built for Edgewood Arsenal workers, hold decades of accumulated debris in duct runs that were never designed for our humidity. We serve every Edgewood neighborhood, from the streets off Hanson Road to the communities near Edgewater Village, and we’ve worked enough crawl spaces between the Bush River and Route 40 to know exactly what this climate does to ductwork. Call (806) 606-6902 and we’ll put a written price in front of you before any work starts.
Why CleanRun Air Duct Cleaning Is Edgewood’s Preferred HVAC Cleaning Company
Our HVAC Cleaning team has spent more than a decade documenting what actually lives inside duct systems across Harford County, and the Edgewood jobs stand apart for one reason: moisture. The tidal wetlands that flank this peninsula don’t just raise the outdoor humidity. They change what happens inside a crawl space, which changes what grows inside duct boots and supply plenums. Homeowners here call us after noticing a musty smell that won’t leave, or after a family member’s allergies worsen during the summer. We show up with the same process every time: camera first, written scope second, work third.
Tomas Reyes, who leads our crews, grew up asking the same question every Edgewood homeowner asks: what am I actually breathing? He built CleanRun around a simple answer: show the customer the photograph before asking them to believe a word we say. That’s been the practice since 2013, across 52,000+ homes, and it holds in Edgewood just as firmly as anywhere else. Every job ends with a documented photo record of every duct run, inside, before and after. No exceptions.
Our HVAC Cleaning Services in Edgewood
Evaporator Coil Cleaning
In Edgewood’s humidity, an evaporator coil becomes a condensation magnet. The coil sits in the air handler pulling moisture out of the air, and when dust and biofilm coat its fins, that moisture becomes a breeding ground. We remove the panel, photograph the coil, and clean it with professional-grade equipment from Rotobrush and Nikro. A coil clogged with gray sludge isn’t just inefficient. It’s actively degrading the air you breathe. Expect $180-$320 for a standard residential coil cleaning in Edgewood, written on the estimate before we start.
Blower Cleaning
The blower wheel moves every cubic foot of air your family breathes. In older Edgewood ranch homes, that wheel often carries a caked layer of dust, pet dander, and sometimes mold spores picked up from the crawl-space side of the system. We remove the blower assembly, clean each blade, and photograph the result. A dirty blower in a home near the Bush River flood plain will recirculate whatever the ducts hold, even after a basic duct cleaning. Blower cleaning runs $120-$220 in Edgewood when bundled with a full system clean.
Air Handler Cleaning
The air handler is the heart of the system, and in Edgewood it’s often located in a damp crawl space or a humid basement. That location matters. We’ve opened air handlers off Trimble Road where the interior surfaces showed condensation damage and visible mold growth at the filter housing. Cleaning the air handler includes the cabinet interior, the drain pan, the coil fins, and the immediate duct connections. $200-$380 is the typical range for a thorough air handler cleaning in this area, and we photograph every surface before closing the panel.
Heat Exchanger Cleaning
When a gas furnace runs in a home with dirty ducts, the heat exchanger collects a fine layer of soot and dust that reduces efficiency and, in some cases, produces a burning odor during the first cold snap. We clean the exchanger surfaces using HEPA-filtered negative pressure and soft agitation tools, never scraping. The process is slow and deliberate, and on older Edgewood furnaces with original exchangers, we document the condition so you know whether the component is sound or nearing replacement. Heat exchanger cleaning adds $150-$280 to a full system job.

BeforeAfterTrusted Brands We Service in Edgewood
We service and clean systems from every major manufacturer, and we stock the consumables Edgewood homeowners need most: filter media, coil treatments, and mastic for boot sealing. Our equipment roster includes Abatement Technologies negative-air machines, Rotobrush agitation systems, and Nikro HEPA vacuums, all of which you can look up independently before we arrive. When we’re working a 1960s ranch off Edgewood Road with an original galvanized trunk line, we’re using tools designed for exactly that kind of contamination, not a shop vac from the truck.
Common HVAC Cleaning Problems We See in Edgewood Homes
- Crawl-space duct boots wicking ground moisture. On low-lying lots near the Bush River, the flexible boot that connects a floor register to the trunk line sits close enough to damp earth for moisture to travel upward. That moisture condenses inside the boot, and black mold follows. We find this on a regular basis in the ranch homes along Hanson Road and around Edgewater Village.
- Original galvanized trunk lines with crushed or disconnected sections. The 1950s and 1960s homes near the old Edgewood Arsenal often still run their original steel trunk ducts. Those connections loosen over decades, and crawl-space air gets pulled in at every gap. Homeowners notice uneven room temperatures and a persistent damp smell.
- Primitive flex-duct runs thick with biofilm. The flex runs installed as replacements in the 1980s and 1990s were never sealed properly at the fittings. Edgewood’s tidal humidity accelerates the buildup of a gray biofilm inside these runs, and standard vacuuming won’t remove it. We use agitation tools and HEPA extraction for this.
- Mold colonization in the supply plenum. The supply plenum is the box where conditioned air enters the trunk line. In Edgewood’s older crawl-space homes, that plenum is often uninsulated metal sitting in damp air for 40 years. We photograph what’s inside before we touch it, and we treat it as a source-removal job, not a quick wipe-down.
Pricing for HVAC Cleaning in Edgewood, MD
A full HVAC cleaning in Edgewood, covering the evaporator coil, blower, air handler, heat exchanger, and all accessible duct runs, typically lands between $340 and $690. Smaller jobs, like a coil-only cleaning or a single-run inspection with photo documentation, start lower. What moves the number is what the camera shows: a disconnected trunk line in a crawl space costs more to put right than a straightforward cleaning, and mold remediation inside a plenum is a separate scope from routine cleaning. We write the price before any panel comes off, and that price is the price. No per-vent add-ons. No surprise line items. Call (806) 606-6902 for a written estimate.

FAQs - HVAC Cleaning in Edgewood
Edgewood sits on a low-lying peninsula between the Bush River and its tidal tributaries, which keeps ambient humidity and crawl-space moisture consistently higher than in upland Harford County towns like Bel Air. That persistent moisture drives mold colonization inside duct boots, plenums, and flex runs at a rate we simply don’t see as often at higher elevations. If you live near the flood plain and smell must every time the blower kicks on, the ductwork is the first place we look. Call (806) 606-6902 and we’ll bring a camera, not a sales pitch.
The most common findings are decades of accumulated dust and pet dander, sections of original galvanized trunk line that have disconnected or crushed under the house, and flex-duct boots where ground moisture has wicked upward and left visible mold at the connection. We also routinely find construction debris from the original build, rattling in the lowest points of the trunk. The good news is this is all fixable. The honest news is that a quick vacuum pass won’t fix it. Have a written scope built around what our camera actually shows.
The short answer is negative-pressure containment. We connect a HEPA-filtered negative-air machine from Abatement Technologies to the duct system before we begin, which keeps the workspace under negative pressure and pulls airborne spores into the filter rather than into your kitchen. Then we agitate and extract the mold from the affected surfaces using soft brushes and HEPA vacuum tools. We finish by sealing the boot or connection that let the moisture in, which is what prevents the mold from returning. If your Edgewood crawl space has been damp for decades, the sealing is the part that matters most.
Yes. The evaporator coil condenses moisture from the air passing over it, and when Edgewood’s humidity runs high all summer, that condensation never fully dries between cycles. Any dust or biofilm on the coil stays wet, and the resulting film insulates the coil and breeds mold directly on the surface. This is why we always include coil inspection and cleaning as part of any Edgewood HVAC job, even when the ducts themselves look clean. $180-$320 for a standalone coil cleaning, written before we begin.
It depends on your household and the extent of the contamination. For a healthy adult, waiting a few days is generally not an emergency, but for anyone with asthma, allergies, COPD, or a compromised immune system, running the HVAC system with active mold in the ducts can worsen symptoms and should be avoided. If you suspect mold, switch the system to fan-off and call us at (806) 606-6902. We’ll schedule a camera inspection and give you a written answer based on what we see, not on vague warnings.
