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.

AfterHow Much Does Air Duct Cleaning Cost in Philadelphia?
Air Duct Cleaning services in Philadelphia typically cost $400 to $900 for a standard single-family home, with most Center City and South Philly rowhouses landing near the middle of that range. Larger homes in Chestnut Hill or on the Main Line often run $900 to $1,500 once you add multiple return trunks and a second system. These figures assume a full-source cleaning: supply and return ducts, registers, grilles, the blower compartment, and the air handler, priced in writing before anyone opens a panel.
Key Takeaways
- Most Philadelphia homes fall between $400 and $900; bigger or multi-system homes run higher.
- Price is driven by how many systems you have, how accessible the ductwork is, and how much debris has built up.
- Dryer vent cleaning runs $125 to $250, and duct sealing is priced separately.
- Beware of “$99 whole-house specials.” That price covers one vent stack, not your home, and it’s the oldest trick in this trade.
- Every Hollis job gets a written price before work starts and the 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what Philadelphia homeowners actually pay, line by line. Treat these as real market ranges, not teaser numbers. The final figure depends on your specific house, which is why we walk the system and write the price down before we start.
| Service | Typical Philadelphia Price Range | Notes |
|---|---|---|
| Single-system home (up to ~10 vents) | $400 – $650 | Most rowhouses and smaller twins fall here |
| Single-system, heavier build-up or poor access | $650 – $900 | Older ducts, finished basements, tight chases |
| Two-system home (upstairs + downstairs) | $800 – $1,200 | Common in suburban Philadelphia and larger twins |
| Large or multi-system home | $1,200 – $1,500+ | Main Line, Chestnut Hill, big detached houses |
| Dryer vent cleaning | $125 – $250 | Often bundled with a duct cleaning visit |
| Duct sealing (mastic) | $500 – $1,400 | Priced by linear feet and access, quoted separately |
| Return to a “before/after” photo record | Included | Standard on every Hollis job |
What pushes you up? More systems, more square footage, and ductwork that’s hard to reach. What keeps you down? A straightforward layout where the tech can get to every trunk and run without crawling through a finished ceiling. We don’t upcharge at the door for “surprises” we should have seen on the walk-through. The price we write is the price you pay, and that’s the whole point of how we run every job.
What Affects Air Duct Cleaning Pricing in Philadelphia
Philadelphia housing stock is old and varied. The same job that takes an hour in a 1990s suburban build can take three in a 1920s West Philly twin with original duct routing. Here’s what actually moves the number.
- Number of HVAC systems. A single forced-air system is one job. Add a second zone or a separate system for the third floor, and you’ve doubled the trunk lines, returns, and air handlers we have to clean. Most two-story suburban homes in Bensalem or King of Prussia run two systems.
- Duct accessibility. Rowhouses in Fishtown and Graduate Hospital were built tight, with ductwork boxed into narrow chases or run through finished ceilings. When a tech has to work through a small access panel, the labor time climbs. Open basement ductwork in Northeast Philly runs faster and cheaper.
- Age and condition of the ductwork. The city’s pre-war housing stock means we regularly find original galvanized trunks, crumbling insulation wrap, or flex duct that’s been patched more than once. Damaged or disconnected runs need to be flagged before they can be cleaned properly, and sometimes that means duct sealing is the smarter spend than another cleaning cycle.
- Debris volume. A house that’s never had the ducts cleaned will hold decades of dust, pet dander, and construction grit. Heavy build-up means slower, more methodical work with the rotary brush system and negative-air machine running longer to capture everything.
- Return vs. supply count. More returns and registers mean more openings to clean, seal, and photograph. A home with 20+ vents takes noticeably longer than one with 10.
- Add-ons you actually need. Dryer vent cleaning and duct sealing are separate line items. We quote them honestly rather than padding the main job to hide them.
One local wrinkle worth naming: Philadelphia’s humidity swings – humid summers along the Delaware, dry cold winters – mean ductwork in conditioned basements can collect moisture and dust that cakes onto the interior surfaces. When that happens, a standard pass won’t cut it, and we’ll tell you up front if your job is the heavier kind before we write the price.
How Is the Work Actually Done (and Why That Affects Price)
A proper cleaning isn’t a guy with a shop vac and a wand. It’s a source-removal process using the same equipment commercial crews run.
- Negative-air method: We hook a Nikro negative-air machine to a main trunk and pull a vacuum on the whole system, so loosened debris gets captured at the source instead of redistributed into your rooms.
- Rotary brush system: A Rotobrush rotary brush agitates dust off the duct walls, then the negative-air machine pulls it out. The brush does the scrubbing; the vacuum does the capturing.
- Filtration products: Where a filter upgrade makes sense, we work with Honeywell, Aprilaire, and Guardsman filtration. A better filter on an existing system can keep ducts cleaner between cleanings, and we’ll explain whether it fits your air handler.
- Duct sealing with mastic: Mastic is a brushable sealant applied to joints and seams. It closes the leaks that let attic or crawlspace air into your supply ducts, which both protects your air quality and takes load off the system.
This is where the cheap bids fall apart. A $99 special often means one vent stack cleaned with a light wand, no negative-air capture, and no photo record. You paid for the appearance of a cleaning, not the cleaning itself. Priced fairly and done right, the job takes real time – which is exactly why the price is what it is. Learn more about dryer vent cleaning if you want that bundled into the same visit.
Is It Cheaper to Repair or Replace?
For ductwork, “replace” rarely makes sense unless the runs are genuinely failing. If your ducts are intact and just dirty, cleaning at $400 to $900 is far cheaper than a full duct replacement, which can run into the thousands, though How Much Does Air Duct Cleaning Cost in Sacramento, CA? (2026 Price Guide) shows similar pricing patterns. If we find disconnected runs, crushed flex, or heavy leakage during a cleaning, we’ll show you the photos and quote duct sealing as a repair. Sealing a leaky system often costs less than homeowners expect and pays back in lower energy bills. We’ll never push replacement when sealing fixes the problem, and that’s a written promise, not a sales line.
How to Save on Air Duct Cleaning in Philadelphia
There’s no magic coupon that beats an honest price, but there are real ways to keep your number down.
- Bundle sensible services. If your dryer vent needs cleaning and your ducts do too, doing both in one visit saves the second trip charge. We quote bundled work up front.
- Handle the small stuff first. Replace your HVAC filter on schedule. A clogged filter pushes more debris into the system and makes every cleaning heavier.
- Fix moisture before it spreads. If your basement runs damp in summer, address it. Moist dust is harder to remove and can lead to duct sealing being needed sooner.
- Get multiple written quotes and compare scope, not just price. A cheaper bid that skips the returns, the blower, or the photo record isn’t cheaper. Compare what’s included.
- Ask for the free estimate. We walk your system and write the price before any work starts. No pressure, no teaser pricing. Call (361) 326-5060 for that estimate.
One more thing on the “save money” angle: the biggest savings usually come from not having to redo the job. A cleaning that leaves debris behind, or a crew that skips the air handler, means you’ll be paying twice. The 365-Day Done Right Promise exists for exactly this reason – if the work fails within a year, we come back and make it right at no charge, including a free second visit.

FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in Philadelphia?
Most Philadelphia homes pay $400 to $900 for a standard single-system cleaning. Two-system homes run $800 to $1,200, and large or multi-system homes can reach $1,200 to $1,500 or more. Call (361) 326-5060 for an exact quote – estimates are free.
Is a $99 air duct cleaning worth it?
No. A $99 “whole-house” special typically covers a single vent stack, not your entire system, and the real price appears once the technician is inside. A legitimate full-source cleaning in Philadelphia costs $400 and up because it includes negative-air capture, rotary brush cleaning of every run, and the air handler, comparable to How Much Does Air Duct Cleaning Cost in San Antonio, TX? (2026 Price Guide). If a bid looks too low for the scope, ask what’s included in writing.
How often should I have my air ducts cleaned in Philadelphia?
Every 3 to 5 years for most homes. Speed that up if you’ve just finished a renovation, if you have pets, if anyone in the house has allergies, or if you’ve had water intrusion in the ducts. Old Philadelphia housing stock with humid basements sometimes needs a shorter interval. Call (361) 326-5060 and we’ll give you a straight answer for your house.
Does duct cleaning actually make a difference?
Yes, when it’s done as source removal with negative-air capture. For Philadelphia homes dealing with construction dust, pet dander, or the grime that builds up in older ductwork, a proper cleaning reduces what’s circulating through your living space. If you want the full picture of what’s involved, our air duct cleaning service page walks through the process step by step.
How much does dryer vent cleaning cost in Philadelphia?
Dryer vent cleaning runs $125 to $250, and it’s often bundled with a duct cleaning visit to save the trip charge. A clogged dryer vent is a genuine fire risk – lint builds up and heat has nowhere to go. Don’t treat it as optional. Call (361) 326-5060 to add it to your estimate.
Can you clean my ducts and seal leaks in the same visit?
Often yes. Duct sealing runs $500 to $1,400 depending on linear feet and access. If we find leaks during the cleaning, we’ll photograph them and quote the sealing separately before any work is added. Nothing gets added to your bill without your say-so. For a closer look at the sealing side, see our duct sealing page.
What to Have Ready Before We Arrive
A little prep makes the visit smoother and keeps the price where we quoted it. Clear access to your furnace or air handler, move anything blocking floor registers, and secure pets. If you have a finished basement with a ceiling access panel, let us know where it is. Small things, but they save time on the job.
If you’re weighing whether to schedule now or wait for a season change, the answer is usually simple: the ducts don’t clean themselves, and the cost doesn’t drop by waiting. Get the estimate, compare the scope against any other bid, and decide from there. We’d rather earn the job by being clear than pressure you into it.
