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 Towson
HVAC cleaning in Towson usually means one of two things: the evaporator coil above your furnace is matted with dust and the blower wheel is caked with years of lint, or the duct runs themselves are carrying debris that keeps recirculating through the house. Most Towson homes we open up fall into both categories at once. We’re CleanRun Air Duct Cleaning, and we’ve worked the Rodgers Forge grid, the Stoneleigh split-levels, and the Anneslie capes long enough to know exactly what’s inside them. If you want a written price before anything comes apart, call (806) 606-6902.
Why CleanRun Air Duct Cleaning Is Towson’s Preferred HVAC Cleaning Company
We don’t ask Towson homeowners to take our word for anything. Every job starts with a written price, per Haven Standard Clause 1, and every duct run we touch gets photographed before and after. You’ll see the camera feed yourself if you want to stand at the access panel with us. That’s been the way since our first job in 2013.
Our technicians are background-checked, uniformed, and introduced by name before they walk through your door. We run Rotobrush and Nikro equipment on the truck, not a shop-vac adapter from a home center. And when a Towson customer shows us a competitor’s written estimate, we put our own number next to it in writing. No pressure, no phone tag. Just a number you can compare line by line.
Towson dispatch is coordinated from our Baltimore office. Crews serve the Towson core directly, and scheduling is handled by a live person when you call.
Our HVAC Cleaning Services in Towson
Evaporator Coil Cleaning
In Towson’s humid summers, your evaporator coil is the coldest surface in the system, which makes it a magnet for every particle the filter misses. The coil sits in the plenum above the furnace, and in older Towson colonials it’s often never been pulled for service. We clean it in place with professional-grade coil cleaners and capture the rinse water, then photograph the result. A matted coil can cost you a 10-15% efficiency loss before you notice any cooling difference.
Air Handler Cleaning
Air handlers in Towson’s split-levels are often shoehorned into basement closets with tight clearances, which is exactly where dust accumulates fastest. We clean the blower wheel, the housing, and the secondary drain pan. A blower wheel caked with dust spins out of balance, which wears motor bearings early. We address the whole assembly, not just the blades you can see from the access panel.
Blower Cleaning
Your blower pushes every particle that slips past the filter through the supply runs and into the rooms. In Rodgers Forge homes with original filters that have been upgraded piecemeal, that blower carries decades of fine debris. We pull the wheel, clean it without bending the fins, and check the motor amp draw before reinstalling. It’s the difference between cleaning the visible part of a system and cleaning the part that actually moves the air.
Condenser Cleaning
The condenser sits outside, where Towson’s mature oak canopy drops a heavy crop of pollen every spring. That pollen coats the coil fins and reduces heat rejection, which drives up head pressure and ages the compressor. We clean condenser coils with low-pressure water and coil-cleaning chemistry, straighten bent fins, and verify the clearance around the unit so air can actually move through it.

Common HVAC Cleaning Problems We See in Towson Homes
- Coal-era soot baked onto duct walls. In Rodgers Forge and Stoneleigh, homes converted from coal to gas decades ago still carry a greasy black residue inside original duct runs. Standard brush-and-vacuum equipment won’t move it. We use aggressive pneumatic agitation with HEPA-filtered negative pressure, then camera-inspect the run to confirm source removal down to bare metal.
- Deteriorated fiberglass duct liner. Many 1960s and 1970s split-levels in Towson were built with fiberglass-lined duct interiors. After 50 years, that liner breaks down and sheds fine particulate into the airstream. Cleaning these systems without proper HEPA containment actually makes the problem worse by loosening the liner debris. We run containment on these jobs every time.
- Disconnected or crushed basement and crawlspace runs. Older Towson homes settle. Duct sections in unconditioned crawlspaces get pulled apart at the seams or crushed by storing boxes on top of them. If we don’t camera-inspect those runs, we’re cleaning a system that’s pulling in basement air and unfiltered dust through the gaps. We find the disconnect, we seal it, and then we clean.
- Matted evaporator coils hidden in the plenum. The coil above the furnace is the last place anyone looks until the AC stops cooling. In Towson, where summer humidity runs high, that coil also grows biological material when it stays wet. We pull the panel, document what’s there, and clean it properly rather than wiping what’s reachable.
Pricing for HVAC Cleaning in Towson, MD
A full HVAC cleaning in Towson that includes evaporator coil cleaning, blower cleaning, and air handler cleaning typically runs $450-$850 depending on system size and accessibility. Condenser cleaning alone runs $125-$225. If we add coil treatment with Guardsman chemistry, that’s an additional $75-$150 per coil. Homes with deteriorated fiberglass liner or coal-era soot require HEPA containment and additional agitation time, which can push a full system cleaning to $900-$1,200. Every job gets a written price before we start, per Haven Standard Clause 1. Bring us a competitor’s written estimate and we’ll give you a free second opinion with our number next to theirs.

FAQs - HVAC Cleaning in Towson
Standard brush-and-vacuum equipment can’t remove it because that soot isn’t dust. It’s a baked-on residue from the coal-to-gas heating conversions that most Rodgers Forge homes went through in the mid-20th century. Decades of gas-heat cycles have cured it onto the galvanized duct walls. Removing it requires aggressive pneumatic agitation plus HEPA-filtered negative pressure, followed by a camera inspection to verify bare metal. In one 1947 colonial, our crew opened a supply register and found the original run coated in a greasy layer that wouldn’t budge with standard methods. We switched tools, scoped the run afterward, and confirmed source removal. If your home was built before 1955 in Rodgers Forge or Stoneleigh, plan on this level of work rather than a basic cleaning. Call (806) 606-6902 for an exact written quote.
Yes, it’s a real problem if the cleaning crew doesn’t account for it. Many 1960s and 1970s split-levels in Towson were built with fiberglass-lined duct interiors. After 50-plus years, that liner deteriorates and sheds particulate. If we clean those runs without HEPA containment, we risk dispersing liner debris into the living spaces. We run containment on every fiberglass-lined system and inspect the liner condition before we start. If the liner is too far gone, we’ll show you the camera footage and recommend liner sealing or replacement as a separate line item. The objective is to get the system clean without making the air inside the house worse.
You won’t see it from the register. Disconnected or crushed runs hide in basements, crawlspaces, and the spaces between floors where decades of settlement and storage have pulled seams apart or flattened sections. The symptoms are predictable: certain rooms never get as warm or cool as others, dust appears quickly after cleaning, and you hear air moving somewhere it shouldn’t. The only way to know is a camera inspection of the runs. We include that on every HVAC cleaning job in Towson because older homes simply have more of these failures. When we find one, we quote the sealing repair separately and in writing before doing the work.
Towson’s established neighborhoods sit under a dense mature canopy of oak and tulip poplar. Every spring those trees release a heavy pollen load that makes its way into return-air systems through every open door and window. In older homes with undersized returns, the problem compounds because the system pulls harder at the remaining open registers. The fix is a combination of return-side cleaning and, in many cases, adding return capacity or upgrading the filter cabinet to a 4-inch media filter. We’ll show you what the return runs looked like before and after so you can see the actual load your system was pulling.
Almost certainly yes, if the coil wasn’t cleaned at the same time. The evaporator coil is the first surface air hits after the filter. If the coil is matted, the system pulls less air through the ducts, runs longer, and uses more energy. Duct cleaning doesn’t address it because the coil sits behind its own access panel above the furnace. In Towson’s humid summers, a wet coil also collects whatever the filter misses. We include evaporator coil cleaning as part of our full HVAC cleaning scope, and we photograph the before and after so you know it was actually done. Call (806) 606-6902 for a written price.
