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.

Why Allentown Homes Are Different
Allentown’s housing stock spans a lot of ground: 1920s brick rowhomes in Center City, mid-century capes and split-levels in West End, 1980s and 1990s colonials up in West Allentown, and newer construction out toward Trexler Park. Each era has its own duct personality. The older homes often run original galvanized ductwork that’s seen 60 or 70 Pennsylvania winters, while newer builds sometimes have flex duct that sags and collects dust at the low points. We work with both every week.
The Lehigh Valley climate does real work on duct systems. Cold winters mean furnaces run hard for five months straight, pulling in dry, dusty air that settles in the return side. Humid summers give dust something to stick to, which is why we often find a gray film coating the inside of supply registers in Allentown homes by August. Homes with window AC units tend to move less air through the ducts in summer, which actually lets more fine dust settle before the furnace kicks back on in October.
One thing we see frequently in Allentown: older homes with no cold-air returns in the upstairs bedrooms. Those systems rely on hallway airflow and undercut doors, which means return air pulls from the dustiest parts of the house: carpet edges, stairwells, and the floor under beds. The ductwork on these systems loads up faster than a modern return-per-room design, and that’s worth knowing whether you clean every three years or every five.
Our Main Allentown Services
Allentown homeowners call us most for two things: dryer vent cleaning (because a clogged vent is a fire risk and a slow dryer) and full air duct cleaning (because the house smells stale or someone in the home has allergies). HVAC cleaning rounds out the work we do here, and each service has its own dedicated page for pricing and specifics.
Dryer Vent Cleaning in Allentown
Dryer vents in Allentown’s older homes are often short runs through a basement wall, but in newer two-story builds the vent can travel 15 to 25 feet through a wall cavity or floor joist before it exits. That’s a lot of surface area for lint to grab onto. We use rotary brush systems and HEPA vacuums to break up and extract buildup along the full run, then verify airflow at the exterior vent cap. Before-and-after photos come with every job so you can see the difference. Dryer Vent Cleaning in Allentown covers full pricing and what to expect.
Air Duct Cleaning in Allentown
Most Allentown duct systems have a mix of supply and return runs we can reach from the furnace and each register. We use negative-pressure extraction with Nikro HEPA vacuums, which means the loosened debris goes straight into the vacuum rather than back into your living room. Older rowhome systems sometimes have tight returns and working around finished basements takes extra care, so we scope out each job before quoting. Air Duct Cleaning in Allentown has full pricing and the step-by-step.
HVAC Cleaning in Allentown
HVAC cleaning in Allentown covers the furnace air handler, blower wheel, evaporator coil, and condensate pan. In older Allentown homes with original furnace closets, the coil and blower are often packed with years of dust and pet hair that the filter never caught. That buildup cuts airflow, makes systems work harder, and can cause frozen coils in summer. HVAC Cleaning in Allentown breaks down the job and what it costs.
