AfterHow Much Does Air Duct Cleaning Cost in North Charleston?
Air duct cleaning in North Charleston typically costs $350 to $800 for a standard single-family home, with most houses landing near $500. Larger homes, homes with more than one HVAC system, and systems that haven’t been cleaned in years run higher, often $800 to $1,500. The written estimate sets the final price, and an on-site estimate costs nothing.
That range surprises some homeowners, because the biggest variable isn’t the size of the house. It’s the condition of the system and what kind of work the ducts actually need. A home can have spotless grilles and still have a supply trunk packed with construction dust from a 2022 renovation. We’ve pulled years of drywall dust out of ductwork in new builds around the Ingleside and Park Circle areas, and that changes the scope of the job before anyone touches a brush.
Here’s the honest version of how pricing works, what moves it, and how to tell whether a quote is built for the work your home actually needs.
Key Takeaways
- Typical North Charleston homes: $350 to $800 for full-system cleaning.
- Larger homes or multiple HVAC systems: $800 to $1,500.
- Dryer vent cleaning alone runs $120 to $250.
- Duct repair for leaks or disconnected runs typically adds $250 to $900, depending on how many sections need work.
- Estimates are free, and prices are set per job.
Air Duct Cleaning Cost Breakdown (2026)
Most air duct cleaning quotes bundle everything into one number, which makes it hard to see what you’re paying for. Below is how we break the job down. These are typical estimates for the North Charleston market in 2026, not fixed prices. Every home gets its own written estimate.
| Service | Typical Price Range |
|---|---|
| Standard whole-home air duct cleaning (up to 12 vents, single HVAC system) | $350 – $550 |
| Whole-home cleaning with additional vents (13-20 vents) | $550 – $800 |
| Larger homes or two HVAC systems | $800 – $1,500 |
| Dryer vent cleaning | $120 – $250 |
| Duct repair (per leak or disconnected run) | $250 – $900 |
| Sealing and reconnecting loose duct sections | $300 – $700 |
What separates the low end from the high end of these ranges? Duct accessibility, the age of the home, whether the ductwork includes flex runs versus rigid metal, and whether repair is needed. A house with a two-story layout and long flex runs is a slower job than a single-story ranch with short metal ducts. And if there’s evidence of a disconnected run or a failed joint, cleaning isn’t the whole job – the ducts need fixing first, or the clean air leaves the system before it ever reaches the room.
That last point is where pricing gets real. The air inside your home is only as clean as the system moving it, and a leaking duct undoes a cleaning. It’s why we offer duct repair alongside cleaning rather than handing you off to someone else. One call covers cleaning and repair, and the estimate reflects both from the start.
What Affects Air Duct Cleaning Pricing in North Charleston
Pricing in this city is driven by a few things that are specific to the housing stock and the climate here, not just square footage.
- Number of vents and HVAC systems. Each vent and each system adds cleaning time. Two-story homes and homes with zoned systems frequently land in the $800 to $1,500 range.
- Construction dust and renovation debris. North Charleston has seen a lot of building and remodeling, and new construction dust is fine and sticky. It settles deep into supply trunks and coats the inside of flex runs. Post-renovation cleaning takes longer and often needs HEPA extraction rather than a light vacuum pass.
- Humidity and the Lowcountry climate. Long, humid summers mean the system runs hard for months, and a house with cooling running near constantly pulls more outside humidity through return leaks. Ducts in unconditioned crawlspaces and garages take the brunt, and a run that’s condensating or sitting in damp air usually needs repair or resealing alongside cleaning.
- Duct condition and accessibility. Rigid metal ducts are easier to brush than long flex runs in tight attic spaces. Disconnected joints, crushed flex pipe and poor routing all slow the job down.
- Age of the home and previous work. Older houses around the Naval Base area sometimes carry decades of accumulated dust, and some have had prior duct modifications that don’t match the original layout. Both affect how much time the job takes.
- Filtration and air quality equipment. Homes with Honeywell or Aprilaire systems already installed sometimes need cleaning timed around filter changes and component checks. We know these systems and can work with what’s already in the house.
Why the Equipment Behind the Price Matters
The cheapest quote is often a truck-mounted vacuum and a shop vac crew. That’s not the same job as rotary-brush cleaning with HEPA extraction, and the difference is visible in the result.
The number on a low bid often reflects what wasn’t done. Rotobrush systems agitate and extract debris rather than blowing it back into the living space. Nikro HEPA-filtered vacuums capture fine particulates at the source instead of redistributing them into the rooms you breathe in. Abatement Technologies air filtration units are the same category of equipment used in professional mold and contaminant remediation, and we use them because homes with allergy concerns or post-renovation dust need that level of capture.
That’s why our pricing reflects a complete cleaning rather than a quick pass. Professional-grade equipment, not improvised tools. If you want to see how that applies to a full-home job, our air duct cleaning page walks through the process. And if you’re comparing local providers, look at Sunstone Air Duct Cleaning and what a complete service actually includes.
Duct Repair Costs in North Charleston
Cleaning without repair is sometimes a waste of money. If a supply run is disconnected, crushed or leaking, you’ll pay for cleaning and still lose conditioned air into a crawlspace. Duct repair in North Charleston typically runs $250 to $900 depending on the number of sections and materials involved.
Common repair triggers in this area include loose joints, crushed flex duct in tight attic spaces, rodent-chewed runs, and connections that pulled apart over time from thermal cycling. A repair estimate is part of the same written quote as the cleaning, so you see the whole job before you commit. It’s a single-call solution rather than a referral to another contractor. For a deeper look at how that service works, see air duct repair.
Dryer Vent Cleaning Cost
Dryer vent cleaning is a separate service and typically costs $120 to $250 in North Charleston. It’s easy to skip because a dryer still dries, but lint buildup in the vent line is a fire hazard, not just a performance problem. If your dryer takes two cycles to dry a load, or the outside vent flap doesn’t open fully when the dryer runs, it’s worth a look.
Many homeowners pair dryer vent cleaning with a duct cleaning visit so both are handled at once. See the dryer vent cleaning page for details on what the service covers.
How to Save on Air Duct Cleaning in North Charleston
You don’t get a lower price by chasing the cheapest bid. You get it by buying the right scope once, so the job doesn’t get repeated.
- Get the estimate on site, not by phone. A phone quote is a guess. An on-site estimate sees the duct layout and the condition before it sets a price. Ours is free.
- Bundle cleaning with dryer vent service. Handling both in one visit usually saves compared to booking them separately.
- Fix leaks before they cost more. A small disconnected run fixed early is a $250 to $400 repair. Left alone, it can mean a repeat cleaning and higher energy bills.
- Address construction dust promptly. If you’ve recently renovated, don’t wait. Fine dust sets into flex duct lining and becomes a much longer cleaning job later.
- Ask what equipment is used. A quote that’s very low often means a vacuum-only approach. For homes with allergies or mold concerns, HEPA extraction is the difference between a surface pass and a proper cleaning.

How Much Does Air Duct Cleaning Cost Per Vent?
Per-vent pricing in North Charleston generally works out to $25 to $45 per vent as part of a whole-home cleaning. But per-vent pricing is a rough tool, not a real estimate. A house with 8 vents and heavy renovation dust can cost more than a house with 14 vents and a clean system. The written estimate should reflect the actual condition of your ducts, not just a vent count.
Is It Cheaper to Repair or Replace Ductwork?
Repair is cheaper than replacement in most cases. A repair runs $250 to $900, while replacing full ductwork is a much larger project that’s rarely necessary unless the system is completely failed or improperly designed. Crushed flex runs, disconnected joints and leaking sections are repairable, and repair is almost always the right first step.
Cleaning with repair is the combination that makes sense for most homes. Cleaning alone on damaged ducts is money spent on air that leaks out before it reaches your rooms. We’ll tell you honestly if replacement is the better path. Call (855) 683-7582 to talk through your situation.
Can Duct Cleaning Be Done the Same Day?
Yes – same-day service is often available for standard whole-home cleanings. Dispatch runs 7am to 7pm, Sunday through Friday, and a free estimate can be scheduled in the same window. Larger jobs or jobs requiring repair may be scheduled into the next available opening.
We answer 24/7, and a call outside dispatch hours is booked into the next opening, Sunday through Friday, 7am to 7pm. To get on the schedule, call (855) 683-7582.
Frequently Asked Questions About Duct Cleaning Costs in North Charleston
How much does air duct cleaning cost in North Charleston?
Air duct cleaning in North Charleston typically costs $350 to $800 for a standard single-family home. Larger homes or homes with two HVAC systems run $800 to $1,500. The written estimate sets the final price, and on-site estimates are free. Call (855) 683-7582 for an exact quote.
Does duct cleaning really make a difference?
Yes, particularly in homes with allergy concerns, recent renovation dust, or aging duct systems. Cleaning removes accumulated dust, debris and contaminants sitting inside the system, and it improves airflow when combined with repair of leaks or disconnected runs. For homes where the ducts are compromised, cleaning plus repair is what actually delivers cleaner air. Call (855) 683-7582 to schedule an estimate.
How often should ducts be cleaned in North Charleston?
Every 3 to 5 years is typical for most homes here, but homes with pets, allergy sufferers, or a recent renovation may need it sooner. The long humid cooling season means the system runs heavily, which pulls more dust and moisture through the ductwork. An on-site look tells you whether it’s time. Call (855) 683-7582 for a free assessment.
Why is my North Charleston home so dusty after cleaning my ducts?
If dust returns quickly after cleaning, the ducts likely have leaks or disconnected runs. Cleaning removes existing dust, but a leaky system pulls new dust in from unconditioned spaces. In homes around North Charleston with ducts in crawlspaces or garages, leaks are common. Repair, not another cleaning, is the fix. Call (855) 683-7582 to have it checked.
What does duct repair add to the cost of cleaning?
Duct repair typically adds $250 to $900 depending on how many sections need work and whether sealing is involved. It’s quoted alongside cleaning in the same written estimate, so you see the full picture before work begins. Call (855) 683-7582 for a free estimate.
Do I need dryer vent cleaning too?
Dryer vent cleaning in North Charleston runs $120 to $250 and is worth doing if it’s been more than a year or your dryer takes longer than it used to. Lint buildup is a fire hazard. Pairing it with a duct cleaning visit is often more efficient. Call (855) 683-7582 to add it to your estimate.
What equipment do you use, and does it affect price?
We use Rotobrush rotary-brush systems, Nikro HEPA-filtered extraction, and Abatement Technologies filtration units – the same category of equipment used in professional remediation. That equipment costs more to run than a simple vacuum, but it agitates and extracts debris rather than redistributing it. It’s the difference between a real cleaning and a quick pass. Call (855) 683-7582 to discuss your system.
What Happens When You Call
We ask a few questions about your home – how many vents, how many HVAC systems, whether there’s been recent renovation or a known leak – and then schedule a free on-site estimate. On the visit, we look at the ducts, check connections and airflow, and write up a scope and price for cleaning, repair or both. You decide from there. Our technicians have up to 8 years of experience, and we use the same professional-grade systems that remediation crews rely on.
Clean ducts and repaired ducts are the goal, not one or the other. And if the air quality in your home matters enough that you’ve already invested in Honeywell or Aprilaire filtration, we can work with what you have and make sure the system delivering that air is worth the equipment on the other end.
Call (855) 683-7582 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.

- Paul Lawson"Told me straight that our ducts were in decent shape and didn't need doing every year like the mailer companies claim."
