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 Lochearn
HVAC cleaning in Lochearn is a different job than it is almost anywhere else in Baltimore County. The housing stock here was built between 1948 and 1965, which means most homes are running original sheet-metal or early fiberboard ductwork that has been collecting dust, deteriorated lining, and condensation-fed growth for six decades or more. Our crews know exactly what they’re walking into when they arrive at a Lochearn rancher or Cape Cod: failed cloth tape at the joints, settled debris in the basement trunk lines, and plenums that have never been opened. If you want a written price before anyone touches a panel, call (806) 606-6902. We’ll put the number in front of you before work begins, every time.
Why CleanRun Air Duct Cleaning Is Lochearn’s Preferred HVAC Cleaning Company
We didn’t build our reputation in Lochearn by showing up with a shop vac and a coupon. CleanRun Air Duct Cleaning has served over 52,000 homes since 2013, and every single one received a written price before work started and a documented photo record when the crew left. In Lochearn specifically, that photo record matters more than most places, because the problems hiding in 1950s ductwork are not things you can see from the register. The camera shows it: a 3-inch debris build-up at the first elbow, gray-green growth coating the plenum, a branch run that was never reconnected after a handyman repair. We show you the before photo. Then we do the work. Then we show you the after.
Tomas Reyes founded CleanRun on a simple rule that is now Haven Standard Clause 1: a written price before any work starts, no exceptions. That means no “call for a quote” runaround and no bait-and-switch pricing once the van is in your driveway. Lochearn homeowners who research before they call tend to appreciate that. They also appreciate that our technicians are background-checked, uniformed, and identified by name before they walk through the door.
We coordinate scheduling from our Baltimore office, with crews serving Lochearn locally throughout the week. When you call (806) 606-6902, a live person answers. You’ll get a straight answer on scheduling, scope, and price.
Our HVAC Cleaning Services in Lochearn
Most homes in Lochearn need more than a quick brushing of the supply registers. The work that actually changes how the system performs happens at the equipment and in the trunk lines. Here’s what our HVAC Cleaning service covers in a typical Lochearn home.
Evaporator Coil Cleaning
The evaporator coil is the cold surface inside your air handler where condensation forms every time the AC runs. In a Lochearn summer, with dew points sitting in the 70s for weeks at a stretch, that coil stays wet constantly. Dust from six decades of recirculated air packs onto the wet surface, reducing cooling efficiency and feeding whatever is growing on the fins. We remove the coil access panel, document what’s there, and clean the coil with the proper chemistry and rinse procedure. In many 1950s-era air handlers, this is the first time the coil has ever been touched since the unit was installed.
Air Handler Cleaning
The air handler houses the blower wheel, the motor, and often the coil in a single cabinet. Lochearn’s original furnaces were often installed with the air handler in a cool, damp block-wall basement, which means condensation forms on the cold cabinet surfaces during summer. That moisture is exactly what causes the microbial growth we consistently find inside these units. We clean the blower housing, the blower wheel blades, the cabinet interior, and the accessible motor vents. Then we photograph every surface before and after so you can see the difference between real source removal and just wiping down the outside.
Blower Cleaning
Blower wheels in Lochearn’s original equipment have been spinning through the same air for decades. The curved blades collect a dense, felted layer of dust that throws the wheel out of balance and reduces airflow across the coil and heat exchanger. We remove the blower assembly, clean each blade individually, and reinstall it. On older furnaces, we also check for thermal limiter trips caused by overheating from a clogged blower wheel. That’s a failure we see repeatedly in Lochearn: the blower motor overheats, the limiter trips, and the homeowner assumes the furnace is dead when the problem is simply a lifetime of accumulated dust on the wheel.
Condenser Cleaning
The outdoor condenser is the part of the system that rejects heat in summer. Lochearn’s small, established lots mean most condensers sit close to the house, often shaded by mature trees that have been dropping leaves, pollen, and seed matter for decades. A clogged condenser coil forces the compressor to run harder and longer. We clear debris, clean the coil fins with the appropriate coil cleaner, and verify airflow. It’s straightforward work that makes an immediate difference in how the system runs during a humid Baltimore County summer.

BeforeAfterTrusted Brands We Service in Lochearn
Our crews work on all residential equipment, and we’re running professional-grade tools from brands you can look up: Rotobrush for negative-pressure source removal, Nikro for HEPA-filtered extraction, and Guardsman for coil treatments and sanitizing chemistry. We name them because you should be able to verify what’s being used before you agree to a price. If a competitor hands you a written estimate and won’t tell you what equipment they’re running, that’s an answer in itself. Our service trucks are stocked for the equipment most common in Lochearn’s 1950s and 1960s installations, which means we don’t have to run back and forth for parts mid-job.
Common HVAC Cleaning Problems We See in Lochearn Homes
- Failed cloth tape at duct joints. The original installers used cloth-backed tape, not mastic. In Lochearn’s humid summers and cold dry winters, that tape dries, cracks, and falls away. Every open joint becomes a leak that pulls damp basement air into the return side and pushes conditioned air into the block walls. The fix is resealing with mastic, which we do as part of the cleaning when accessible.
- Condensation-fed mold at the basement plenum. Lochearn’s block-wall basements stay cool and damp in summer. Cold supply air moving through the metal plenum causes condensation on the outside, and in turn, moisture intrusion at the seams. Over decades, the lowest sections of the system develop mold colonies that line the plenum. This is not dust. It requires source removal, not a light brushing.
- Settled debris in the main trunk lines. We photograph trunk runs in Lochearn homes and consistently find loose fill, sand, dead insects, and construction debris settled in the low sections. Since the ducts were never sealed properly, they’ve been drawing from the basement environment for 60 years. Our negative-pressure setup with HEPA filtration extracts this material from the supply and return runs, including the low spots where it has compacted.
- Crushed or disconnected branch runs. Lochearn’s ranchers and Cape Cods route ductwork through ceiling cavities in unfinished basements. When someone does repair work, branches get knocked loose or crushed and never reconnected. The result is a register that delivers almost no air while the system runs harder elsewhere. A camera inspection identifies these disconnects. Sealing and reconnecting them is part of a proper cleaning, not an upsell after the fact.
- Blower motor overheat from a lint pathway choked with settled dust. Original furnace blowers were not built to pull against a wheel and housing clogged with years of accumulated debris. When the motor overheats, the thermal limiter trips. We see this pattern regularly in Lochearn: a homeowner thinks the furnace has died, but the blower was never cleaned in the 40 or 60 years since the house was built.
Pricing for HVAC Cleaning in Lochearn, MD
Every Lochearn job gets a written price before any work starts, and that price is based on the scope of work we identify during inspection, not on a teaser rate that balloons once we’re inside. For a full HVAC cleaning that includes evaporator coil cleaning, blower cleaning, and supply and return trunk extraction in a typical Lochearn rancher or Cape Cod, homeowners should expect to pay between $650 and $1,200 depending on system size, number of runs, and how much sealing is required. Air handler cleaning alone typically runs $300 to $500. Blower cleaning, including removal and reinstallation, is generally $200 to $350. Condenser cleaning runs $150 to $250. If we identify disconnected branch runs or failed joints that need sealing, the sealing work is quoted separately in writing, with materials and labor itemized. We never quote a price per vent, and we never start work without your signature on the scope. That’s Haven Standard Clause 1, and it has been since the first CleanRun job in 2013. Call (806) 606-6902 for a written estimate based on your system, not a generic square-footage formula.

FAQs - HVAC Cleaning in Lochearn
The mold comes from condensation on the plenum itself. Lochearn’s block-wall basements stay cool and damp through the humid months, and when cold supply air moves through the metal plenum, the exterior surface cools below the dew point. Moisture condenses on the metal, seeps into the seams where the original cloth tape has failed, and creates a persistently damp environment inside the lowest sections of the duct. This is not caused by water intrusion from the foundation. It’s the physics of cold metal in a humid basement. The fix is source removal, not disinfecting the register. If you’ve seen dark staining at the plenum seams, call (806) 606-6902 and we’ll show you on camera what we’re working with before we touch it.
We document the disconnect, show you the photo, and include the reconnection and sealing in a written scope before any work begins. In most cases, the branch run has simply been knocked loose from a main trunk in the ceiling cavity during a prior repair. We reconnect it, seal the joint with mastic, and verify airflow at the register after the repair. The camera inspection is part of the job, which means you see the problem before you pay for the fix. We don’t do surprise add-ons after the fact.
Because the problems in Lochearn’s original 1948-1965 ductwork are not just surface dust. Open joints, condensation-fed growth at the plenum, and settled debris in the trunk lines all require equipment that does more than agitate the walls of the duct. Our negative-pressure setup with HEPA filtration puts the system under vacuum while mechanical agitation removes the source material from the walls and low points. Then we address the cause of the recurrence: the failed tape, the open joints, the missing sealing. Brushing alone leaves the cause in place, which means the ducts look better for six months and then look the same as before.
An original 1950s air handler in Lochearn should be inspected and cleaned every one to two years, particularly if it sits in an unfinished block-wall basement. Newer systems in newer construction can often go three to five years between cleanings, but the combination of six-decade-old equipment, failed sealing, and persistent basement humidity means these older units accumulate significant debris and microbial growth in a much shorter window. The more the system runs in a humid summer, the faster the contamination builds. If you can’t remember the last time your air handler was opened, it’s time to have someone open it and show you what’s inside.
Negative pressure is the difference between vacuuming and just moving dust around. In a Lochearn rancher with a 50-foot trunk line, the problem is not the dust on the first few feet of duct near the register. It’s the compacted debris settled at the low points deep in the trunk. Negative pressure means we connect a HEPA-filtered extraction unit to the system so that the entire trunk is under vacuum while the agitation runs inside. The material is pulled to the extraction point, passed through HEPA filtration, and contained, not released into the living space. Then we photograph the trunk before and after so you can see the difference. That photo record is a standard deliverable, not an option. Call (806) 606-6902 and ask for our written scope with the documentation included.
