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 Hollis Air Duct Cleaning Is Flourtown’s Preferred Air Duct Cleaning Company
We’ve been cleaning ducts in Flourtown long enough to know which homes near Paper Mill Road have access panels buried beneath original flagstone patios, and which century-old stucco places still run galvanized ductwork from the 1920s. That local knowledge saves time and prevents damage.

Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday morning to schedule your Air Duct Cleaning appointment.

Commercial Air Duct Cleaning in Flourtown
Commercial Air Duct Cleaning in Flourtown covers office buildings, retail spaces, and multi-unit properties where code compliance and occupant health are non-negotiable. We use Nikro negative-air machines to contain debris during cleaning, paired with HEPA filtration to protect your workspace. Most commercial systems in Flourtown run $800 – $2,400 depending on square footage and system complexity, with written pricing provided before any work begins.
System Inspection and Documentation
We start with a video inspection of your commercial ductwork, recording condition and contamination levels for your records. This documentation supports insurance claims, lease requirements, and HVAC maintenance logs that Flourtown property managers need on file.
Post-Cleaning Verification
After cleaning, we run a second video pass to confirm debris removal and system integrity. You’ll receive both recordings plus a written report, so there’s no question about what was done and how your system now performs.
Air Duct Cleaning Services in Flourtown
Air Duct Cleaning Services in Flourtown address the specific challenges of pre-1940 housing stock, where original galvanized or early transite ductwork requires careful handling. Our Air Duct Cleaning in Flourtown crews use Rotobrush rotary brush systems for mechanical agitation, followed by negative-air extraction to pull loosened debris out of your home entirely. A typical full residential cleaning runs $350 – $650, with supply-only or return-only cleanings starting around $200 – $350.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back for reconditioning. We clean both separately because contamination patterns differ, returns typically collecting more dust and supply lines showing more mold in Flourtown’s humid summer months.

Video Inspection and Mold Assessment
Our technicians feed cameras through your ductwork before and after cleaning, showing you exactly what we’re dealing with. In Flourtown homes with damp basements or former springhouse crawl spaces, we specifically check for mold growth that standard cleaning alone won’t solve.

Common Air Duct Cleaning Problems We See in Flourtown Homes
- Asbestos-wrapped duct joints in pre-1940 homes. Many Flourtown fieldstone and stucco houses still have original asbestos insulation on galvanized ductwork. We identify these joints before any aggressive cleaning begins and adjust our method to prevent fiber release.
- Undersized return ducts pulling basement moisture. Older systems near Bethlehem Pike were designed for heating-only operation and can’t handle modern air conditioning loads. That creates negative pressure that draws damp basement air, and mold spores, into your living space year-round.
- Radon mitigation lines interfering with duct access. Homes along the Bethlehem Pike corridor often have retrofit radon systems sharing chases with original ductwork. Our technicians map these configurations before cutting access to avoid damaging mitigation piping.
- Pollen and valley humidity cycling through year-round HVAC use. Flourtown’s location near the Wissahickon Valley means heavy spring pollen loads and summer humidity that coat duct interiors. We see the thickest buildup in homes that never open windows, relying entirely on systems that run continuously.
