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 Johnstown Homes Are Different
Johnstown’s housing stock splits into two distinct categories, and each presents its own ductwork problems. On the outskirts, you’ll find older farmhouses with original galvanized ductwork from the 1800s and early 1900s. That metal corrodes, sheds rust particles into airflow, and often wasn’t designed for modern forced-air systems. In the newer subdivisions on the south and west sides, built after the 2018 tornado damage, flexible ductwork is common but initial sealing was frequently rushed during reconstruction. We regularly find gaps at plenum connections and collapsed runs in attics that never got proper inspection.
The 2022 EF-1 tornado created a specific issue we still encounter: blown-in attic insulation sucked into return ducts through damaged roof structures. Fiberglass particles circulate for years afterward without professional negative-air cleaning. Johnstown’s humid continental climate compounds this, summers here are warm and wet enough to grow mold inside poorly insulated duct runs, while spring and fall pollen from surrounding farmland loads up return grilles fast. Cold winters mean furnaces run hard for months, baking accumulated dust into duct walls.
Our Main Johnstown Services
Johnstown homeowners call us most often for these three jobs. Each has its own dedicated page with full details on methods, pricing, and what to expect.
Air Duct Cleaning in Johnstown
We clean supply and return ducts with Rotobrush rotary brush systems for light-to-moderate buildup, and Nikro negative-air machines for heavy contamination or post-construction debris. In Johnstown, the negative-air method is often necessary for homes rebuilt after tornado damage, where drywall dust and fiberglass settled deep in trunk lines. We run a camera before and after so you see what was in there. Air Duct Cleaning in Johnstown covers full pricing and what the visit includes.

Dryer Vent Cleaning in Johnstown
Clogged dryer vents are a fire hazard and they waste energy. In Johnstown’s older farmhouses, vent runs are often long, rigid metal through multiple walls, while newer builds may have flexible transition ducts that sag and trap lint. We clean the full run from dryer to termination with rotary brushes and high-velocity air tools, then test airflow with a manometer. Dryer Vent Cleaning in Johnstown has full details.

Duct Sealing in Johnstown
Leaky ducts waste 20 – 30% of heated and cooled air before it reaches rooms. In Johnstown’s post-2018 construction, we find poorly sealed plenums and disconnected flex runs regularly, older galvanized systems have seams that have worked loose over decades. We seal with mastic and mechanical fasteners, then pressure-test to verify. Duct Sealing in Johnstown explains the process and pricing.
