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.

AfterAir Duct Cleaning Company in Malvern, PA
Air duct cleaning in Malvern typically runs $450 – $850 for a whole-home system, with most jobs scheduled within a week and completed in a single visit. What changes the price here isn’t the company, it’s the house: century-old stone twins in the borough carry different challenges than the flexible-duct executive homes built in Willistown and East Whiteland during the 1990s and 2000s. We dispatch crews from our Philadelphia office and serve Malvern homes with equipment from Rotobrush and Nikro, pricing every job in writing before we start. Call (361) 326-5060 for a free estimate.
Why Malvern Homes Are Different
Malvern sits at a housing crossroads that most towns don’t have. The borough itself, especially along King Street and the side streets off Lancaster Avenue, is packed with 1890s – 1930s twins, singles, and stucco-over-stone homes. Many still run on retrofitted forced-air ductwork or even partial gravity-system remnants. In these houses, ducts often pass through unheated stone basements where mid-Atlantic humidity causes metal to sweat through July and corrode at the seams, a condition we almost never see in newer construction just a mile out.
The surrounding townships, Willistown, East Whiteland, and Tredyffrin, tell a different story. Toll Brothers-style executive homes from the 1980s through the early 2000s dominate, built with long trunk-and-branch runs of flexible plastic-core ductwork. That material sags, kinks at elbows, and collects dust in ways rigid metal doesn’t. Summer cooling seasons in Malvern’s humid climate run long enough that poorly insulated flex duct in unconditioned attics traps condensation, feeding mold and musty odors that winter heating then dries and blows through the house as dust.
A crew working here has to read both languages: asbestos-era caution on the old borough systems and high-velocity knowledge on the newer flexible-duct installs. One approach doesn’t cover both.
Our Main Malvern Services
Malvern homeowners call us most often for three jobs, each with its own local conditions and pricing. Every service runs under The Garrison Standard: written price before work starts, background-checked uniformed technicians, and the 365-Day Done Right Promise.
Air Duct Cleaning in Malvern
Whole-system duct cleaning in Malvern means pulling debris from both the supply and return sides with a rotary brush system and negative-air containment. In the borough’s older homes, we’re often working around retrofitted duct runs that narrow or turn sharply in stone basements; in the township executive homes, we address sagging flex duct and the dust that collects at every kink. We use Rotobrush rotary systems and Nikro negative-air machines, and we photograph the before and after so you see what came out. Air Duct Cleaning in Malvern covers full pricing and what the visit includes.
Dryer Vent Cleaning in Malvern
Dryer vent cleaning matters more in Malvern than in drier climates because humidity keeps lint sticky and dense, packing it into elbows and exterior hoods. We see this especially in the townships where longer vent runs through finished basements create more friction points. A blocked dryer vent isn’t just inefficient; it’s a fire risk. We clean the full run from the back of the dryer to the exterior termination, test airflow before and after, and give you a written result. Dryer Vent Cleaning in Malvern has the full breakdown.
Duct Sealing in Malvern
Duct sealing in Malvern addresses the leakage that wastes conditioned air and pulls attic or basement air into your system. In older borough homes, we seal corroded metal seams and gaps where retrofits meet original construction; in newer township homes, we target disconnected flex duct collars and poorly sealed plenums. We apply duct sealing mastic and mechanical fasteners, then pressure-test to verify the seal. Duct Sealing in Malvern explains when sealing beats replacement.

What pushes Malvern prices toward the high end: older borough homes with limited basement access, multiple HVAC zones, or corroded metal duct that needs repair before cleaning can begin. Newer township homes with long flex-duct runs sometimes need more time at each register. The price we write down before we start is the price you pay; it does not move at the door.
