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.

We serve every Hanover neighborhood, from the townhome clusters off Dorsey Road to the newer communities along Arundel Mills Boulevard, with written pricing delivered before any panel comes off.

Why CleanRun Air Duct Cleaning Is Hanover’s Preferred HVAC Cleaning Company
We’ve cleaned enough air handlers in Hanover to know exactly what hides inside them. A three-story townhome off Ridge Road presents a different job than a single-family home near Severn-Danza Park, and our pricing reflects that difference up front, not after we arrive. The HVAC Cleaning team documents every duct run with before-and-after photography, so when we hand you the photo record at the end of the job, you see what was actually removed. That documentation matters in a market where too many companies sell a visit, not a result.
Tomas Reyes built CleanRun on a simple rule: a written price before work starts, every time, no exceptions. That’s Haven Standard Clause 1, and it’s printed on every estimate we leave in Hanover. Our technicians are background-checked, uniformed, and identified by name before they set foot in your home. We don’t ask for trust because we’ve been around a long time. We earn it by showing you the inside of your ducts before and after, with a 365-Day Done Right Promise in writing that stands behind the work.
When we schedule a Hanover job, we dispatch crews from our Baltimore office, but the technicians working in your home know this area. They know the three-story vertical runs, the tight air handler closets, and the construction-era debris that hasn’t moved since the drywall crew left. That local knowledge changes how we approach every cleaning, from setup to final camera inspection.
Our HVAC Cleaning Services in Hanover

Air Handler Cleaning
This is the component we emphasize most in Hanover. The compact mechanical closets common in townhomes along Route 100 and around Arundel Mills position air handlers so tightly against finished walls that flex-duct connections bend sharply at the first elbow. We’ve pulled jet-black dust cakes from those bends that were ten years in the making, a mix of drywall dust, fiberglass insulation debris, and corridor particulates. A standard air handler cleaning in Hanover runs $180-$260 as part of a full-system job, and we camera-inspect every connection after cleaning to confirm no kink remains.

Evaporator Coil Cleaning
Maryland’s humid summers keep your evaporator coil wet from June through September. Combined with the elevated fine-particulate load from BWI’s approach corridors, that moisture turns the coil into a capture surface for anything moving through your return side. A dirty coil in a Hanover home typically costs 15-20% more to cool the same square footage. Our evaporator coil cleaning is included in a full HVAC Cleaning in Hanover scope at $110-$160 when bundled, and we use professional-grade cleaners from Abatement Technologies rather than household sprays that can damage fin coatings.

Blower Cleaning
The blower wheel spins at 1,000+ RPM, and every rotation picks up whatever the filter missed. In Hanover, that often includes a fine layer of jet-exhaust soot that adheres to the wheel vanes and reduces airflow. A blower cleaning in Hanover runs $120-$190 depending on access. We remove the blower assembly, clean both sides of every vane, and photograph the wheel before reinstalling. The difference in airflow after a proper blower cleaning is something you’ll feel at the registers, not something we claim.

Condenser Cleaning
Your outdoor condenser takes the brunt of whatever Falls Road traffic and local landscaping throw at it. Cottonwood, pollen, grass clippings, and construction dust all pack into the coil fins and choke the system’s ability to reject heat. We clean and comb the condenser coil, clear the drain lines, and check refrigerant pressures as part of a complete HVAC service. Condenser-only cleaning in Hanover runs $150-$220 for a standard residential unit.

Heat Exchanger Cleaning
For gas furnace systems, a dirty heat exchanger is a safety issue before it’s an efficiency issue. The fine particulate load in Hanover shortens the interval between heat exchanger cleanings compared to homes further from the flight path. We inspect for cracks, clean the exchanger surfaces, and document the condition with photos. Heat exchanger cleaning runs $160-$240 as a standalone service or $120-$180 when bundled with a full HVAC cleaning.

Coil Treatment
After cleaning, we apply an antimicrobial coil treatment that slows mold and biofilm regrowth through Hanover’s humid summer cycle. This isn’t a replacement for cleaning; it’s a protective step that extends the work. Coil treatment runs $60-$90 per coil and is included in our full-system package rather than sold as an add-on surprise.

AfterTrusted Brands We Service in Hanover
Most Hanover townhomes were built with mid-tier builder-grade equipment, and most of it is still running a decade or more later. That’s fine. We clean and service whatever’s in your home, and we keep parts on hand for the brands we see most in this market, including Honeywell controls, Aprilaire media cabinets, and Guardsman access panels. If you know your system’s make and model when you call, we can usually confirm part availability before anyone drives to Hanover.
Common HVAC Cleaning Problems We See in Hanover Homes

- Mid-floor horizontal runs packed with debris. The three-story townhome layout common off Dorsey Road and around Arundel Mills means long vertical duct runs with horizontal sections at floor level. Debris settles in these horizontal stretches and stays there for years because standard cleaning methods never reach them. We use negative-pressure extraction with agitation tools specifically for these sections, then camera-inspect to confirm removal.
- Kinked flex-duct connections behind tight air handler closets. This is the single most common finding in Hanover townhomes built between 2000 and 2015. The mechanical closet is too tight, the flex duct bends too sharply, and debris catches at the first elbow. A cleaning that skips this connection leaves the source of the restriction in place.
- Construction-era debris still in the ducts. If your Hanover townhome was built during the boom years and never cleaned before first occupancy, the original drywall dust, sawdust, and fiberglass insulation debris are almost certainly still in the trunk lines. We find this in roughly seven of ten first-time cleanings in this market.
- Accelerated fungal growth from BWI-corridor particulate load. The jet-exhaust soot and ultrafine particulates that settle in local ductwork give mold and biofilm a food source that homes a few miles away don’t have. Combine that with Maryland’s summer humidity, and the regrowth rate is faster here than in Severn or Odenton. This is why we recommend a coil treatment after cleaning in Hanover specifically.
Pricing for HVAC Cleaning in Hanover, MD
A complete HVAC cleaning on a standard three-story Hanover townhome runs $425-$685. That is one flat price per system, written before work begins, covering the air handler, evaporator coil, blower, supply and return ducts, and a camera inspection of every run. Single-family detached homes in the older sections near Route 100 typically fall at $550-$800 depending on square footage and system configuration. We do not price per vent. Haven Standard Clause 1 means the price on your estimate is the price on your invoice, and if we find something unexpected during the job, we stop work and show you exactly what we found before any additional cost is discussed.

FAQs - HVAC Cleaning in Hanover

Most Hanover townhomes need a full HVAC cleaning every 3-4 years, not the yearly interval some companies push. The BWI particulate load accelerates contamination compared to homes away from the flight corridors, but a properly cleaned and sealed system still holds up for multiple years. If you’ve never had your ducts cleaned and your townhome was built in the 2000s or early 2010s, schedule an inspection now, because construction debris has likely been sitting untouched since day one. Call (806) 606-6902 and we’ll help you determine whether you need a cleaning or just a filter upgrade.
No. We quote one flat price per system before any work starts, regardless of how many registers your townhome has. Per-vent pricing is how companies turn a townhome’s typical layout into a much larger invoice than the advertised number. Haven Standard Clause 1 requires a written price before work, and that price is what you pay. Call (806) 606-6902 for an exact quote on your system.
Yes, and we do it on every job as a standard deliverable, not an upsell. We camera-inspect the inside of every duct run before cleaning, photograph the debris we find, and photograph the same runs after extraction is complete. That Documented Photo Record is part of what you receive with every CleanRun job in Hanover. If a company won’t show you the inside of your own ducts, ask yourself what they’re doing with the vacuum hose.
That black dust in a Hanover home is most often a combination of jet-exhaust soot from the BWI flight corridors and construction-era drywall dust that was never removed before first occupancy. Your filter catches what passes through it, but nothing you do at the filter will address debris already packed into the duct runs behind it. The only way to remove it is mechanical agitation with negative-pressure extraction, which is exactly what we do. Call (806) 606-6902 and we’ll tell you what’s actually in your ducts.
No, and we won’t pretend otherwise. A proper HVAC cleaning on a Hanover townhome takes four to six hours with two technicians, a negative-pressure unit, agitation tools, and camera inspection. Anyone who shows up the same day with a shop vac and a coupon is not cleaning your system. We schedule Hanover jobs with a written scope and a fixed price, and we show up when we say we will. Call (806) 606-6902 to schedule your cleaning.
