Indoor air quality isn’t just a winter issue in the South Hills. Pollen-heavy springs, humid summers, and long heating seasons keep your HVAC moving year-round. Done right, professional duct cleaning can reduce dust, help your system perform better, and support healthier air. Done wrong, it’s a waste (or worse). Below is a complete guide on what actually warrants cleaning, what a proper job includes, how often to do it, and local tips for South Hills PA communities.

Do you really need duct cleaning? When it is worth it
The EPA does not recommend routine duct cleaning on a schedule. It’s recommended as needed especially when there’s visible mold, vermin, or excessive dust/debris being released from registers. If you clean, clean the whole system (supply/return ducts, coils, blower, drain pan, housing), or you’ll re-contaminate quickly.
Red-flag situations:
- Musty odors, visible growth on bare metal components, or wet/contaminated duct liner/insulation. Wet/moldy porous insulation should be removed and replaced.
- Rodent/insect activity inside ducts.
- Plumes of dust from registers. Post-renovation debris. Heavy interior smoking. Multiple shedding pets.
What a proper duct cleaning includes (and what it doesn’t)
Look for the NADCA “source removal” method. Place the system under negative pressure with a high-powered vacuum, then agitate interior surfaces (brushes, air whips, skipper balls) to dislodge debris before capture. Partial “blow-and-go” jobs or just sticking a shop-vac in a vent won’t cut it.
At Bactronix, our process follows all recommended guidelines and is totally thorough:
- Whole-system cleaning: supply & return trunks/branches, registers/grilles, blower, housing, coils, drain pan, and air handler cabinet.
- Access panels cleaned & resealed as needed per NADCA standard. Cleanliness verification before wrap-up.
- Targeted antimicrobial use only when warranted and only with EPA-registered products on appropriate surfaces.
Dryer vent cleaning belongs in this conversation
Dryer exhaust is a top fire source. Failure to clean is the leading factor in U.S. home dryer fires (2018–2020 data). Annual dryer vent cleaning is a simple safety win especially for second-floor laundry rooms with long runs.
Book Dryer Vent Cleaning the same day as your ducts to save a trip and reduce downtime.
How often should South Hills homes clean ducts?
There’s no one-size schedule. NADCA advises annual inspection and cleaning as needed. Many of our South Hills clients end up cleaning around every 3–5 years depending on pets, allergies, smoking, humidity, and renovations.
If you’ve never had your ducts cleaned before, it’s probably needed!
What We’re Seeing in South Hills Homes
- Mt. Lebanon has a lot of brick & plaster homes with finished basements: We commonly find return-side dust mats and basement returns pulling dust.
- Weirton & Murraysville split-levels with longer runs: Long branch lines benefit from mechanical agitation to pull settled dust from the runouts.
- Cranberry (multi-zone systems): Make sure each air handler/zone is included. Don’t pay for one and miss the other.
- Washington, Butler, Beaver: Post-remodel cleanings after plaster/drywall work prevent grit and dust recirculation.
Frequently Asked Questions (FAQs)
Not always. Clean only when needed, if you see visible mold, vermin, or dust blowing from registers.
Visible growth on bare metal parts, pest activity, or debris being released from vents. If fiberglass duct liner is wet/moldy, replacement is recommended (not “spray and pray”).
It varies by home/system, but generally get time estimates during inspection. Most homes take several hours (often ~2–4+ for one system when done thoroughly).
Typical range $550-1,200 per system depending on size, access, contamination, and scope. We’ll give you a process before we start.
Clean When It Matters, Do It the Right Way
For South Hills homeowners, duct cleaning isn’t a yearly chore. It’s an as-needed service that pays off when you have visible debris, moisture/mold issues, pest activity, post-renovation dust, or stubborn musty odors. When you do clean, insist on whole-system, negative-pressure “source removal” with mechanical agitation and coil/blower/drain-pan service. Pair the visit with dryer-vent cleaning and consider duct sealing for comfort and energy savings.
