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.
Air Duct Cleaning Company in Lochearn, MD
Air duct cleaning in Lochearn, MD typically costs $450 – $850 for a standard single-system home, depending on the size of the house and how long it’s been since the last cleaning. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family, and we handle duct work in Lochearn’s mid-century colonials and split-levels with equipment built for real cleaning, not a truck-mounted shop-vac shortcut. Call (737) 727-2314 and we’ll give you a written price before any work starts.
Why Lochearn Homes Are Different
Lochearn’s housing stock is the story here. The neighborhood was largely built out between the 1940s and 1970s, which means homes with original ductwork that’s now 50 to 80 years old. That changes the job. Older galvanized steel ducts hold up well, but the joints, seams, and return plenums have had decades to collect a layer of fine dust, pet hair, and the occasional surprise left by a previous owner’s renovation. We regularly find drywall dust packed into return ducts in Lochearn homes that were renovated without sealing off the vents first.
Climate matters too. Baltimore County summers push humidity into the low 80s and beyond for weeks at a time. When conditioned air moves through dirty ducts, condensation forms on the dust layer and turns it into something that clings to the interior surfaces. That’s part of why a simple visual check of your vent covers won’t tell you much about what’s further down the line. Homes near the Woodmoor side of Lochearn also sit close enough to Liberty Road that road dust, pollen from the tree-heavy lots, and the usual seasonal leaf litter find their way into intake registers faster than in more open subdivisions.
Most Lochearn homes are single-zone systems with the furnace in a basement utility closet or a crawlspace, which makes access straightforward. The trade-off is that decades of filter changes and air movement mean the blower, coil, and return elbow all need attention in the same visit, not just the supply runs.
Our Main Lochearn Services
Most Lochearn homeowners call us for one of three jobs: a full air duct cleaning, an HVAC system cleaning that includes the blower and coil, or a dryer vent cleaning that restores airflow to the outside. Each has its own dedicated page with specific pricing and what to expect.
Dryer Vent Cleaning in Lochearn
Dryer vents in Lochearn’s older homes run short and straight when the laundry is on an exterior wall, but basements and interior laundry closets often push the run to 15 or 20 feet with elbows. Lint, moisture, and heat combine in those bends until airflow drops and drying times stretch past one cycle. We clean the full run from the dryer connection to the exterior termination, clear the lint trap housing, and verify airflow at the outside vent. The typical vent in a Lochearn split-level is done in under two hours. Dryer Vent Cleaning in Lochearn

Air Duct Cleaning in Lochearn
A full air duct cleaning in Lochearn covers every supply and return run, the trunk lines, and the plenums on both sides of the furnace. We use a Rotobrush rotary brush system to agitate the interior surfaces, paired with a Nikro HEPA vacuum creating negative pressure so loosened debris goes into the collection unit, not back into your living room. On homes off Essex Road or near Sudbrook Park, we often see return ducts packed with construction dust from decades-old renovations. Air Duct Cleaning in Lochearn

HVAC Cleaning in Lochearn
HVAC cleaning goes beyond the ductwork to the equipment itself: the evaporator coil, blower wheel, blower housing, and drip pan. In Lochearn’s humid summers, a dirty coil surface is what drives up your electric bill and shortens compressor life. We pull the blower, clean the wheel with a soft-bristle brush and compressed air, and treat the coil with a proper evaporator cleaner. Done alongside a duct cleaning, the whole HVAC cleaning usually adds two to three hours to the visit. HVAC Cleaning in Lochearn

Whatever the number is, you get it in writing before we touch a single register, and that number does not change when the technician arrives.

No. Duct cleaning is interior work that doesn’t touch common areas, exterior finishes, or shared infrastructure. No Lochearn HOA or county permit applies to cleaning or replacing your ductwork. If you decide to add exterior dryer vent work, that’s still a standard homeowner repair without permit requirements.
