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.
Fast, Reliable Air Duct Cleaning Across Wilmington
Air duct cleaning in Wilmington typically runs $450 – $850 for a full system on a standard single-family home, and the real work takes about 3 to 5 hours. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we serve Wilmington with a simple promise: one flat price per system agreed before we start, before-and-after photos of your own ducts, and a 365-Day Done Right Promise that covers every job. Call (737) 727-2314 and a live person answers, any hour.
We know Wilmington’s streets, not just its zip code. From the capes off Church Street to the ranches near Boutwell, we know how these houses were built and what accumulates inside their ductwork. That matters when you’re deciding whether a cleaning is worth it or just a sales pitch.
Why Cardinal Air Duct Cleaning Is Wilmington’s Preferred Air Duct Cleaning Company
Wilmington homeowners call us because we answer the phone and we answer the question. Our technicians are background-checked and arrive in uniform, and before any work begins you get a written price. Not an estimate range. A number. If the work isn’t right within 365 days, we return and correct it at no charge. That’s the 365-Day Done Right Promise, and it applies to every booking without exception.
Our crews operate professional equipment: Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for negative-pressure extraction, and Abatement Technologies containment units when a job calls for it. Most Wilmington homes don’t need a truck-mounted shop vac. They need source removal. That’s the difference between surface dusting and Air Duct Cleaning done properly.
Every Cardinal technician follows The Relay Standard: you get a live trackable arrival window, before-and-after photo documentation, and a digital invoice you can pay from your phone. No four-hour windows. No guessing when the van shows up. You see where we are, you see what we did, and you pay what you agreed to.
Commercial Air Duct Cleaning in Wilmington
Commercial Air Duct Cleaning in Wilmington covers offices, medical suites, salons, and light industrial spaces along Main Street, Ballardvale Street, and the Route 93 corridor. Commercial ductwork sees higher static pressure, longer run times, and more occupant turnover than a house, so buildup accumulates faster and affects more people. A commercial job in Wilmington typically runs $900 – $2,500 depending on square footage, vent count, and access complexity. We quote one flat price after a walkthrough, before anyone touches a duct.
Supply and Return Cleaning for Commercial Spaces
We clean both sides of a commercial system, because return-side neglect is the most common cause of poor airflow in older Wilmington buildings. Supply ducts deliver conditioned air; return ducts pull it back. If returns are choked, the system strains, energy bills climb, and occupants complain about hot or cold spots. We camera-inspect both sides before and after.
Documentation and Compliance
Wilmington commercial clients get before-and-after photos of the duct interiors, not just a receipt. That documentation matters for property managers, building owners, and anyone who needs to show the work actually happened. We clean the air handler and blower motor as part of full system cleaning, because cleaning ducts without cleaning the blower is like changing oil and leaving the old filter.
Air Duct Cleaning Services in Wilmington
Air Duct Cleaning Services in Wilmington center on residential homes, and most of our work here involves older capes and ranches with original sheet-metal trunk-and-branch ductwork. We clean supply ducts, return ducts, and the air handler in a single visit. A typical single-family home in Wilmington runs $450 – $850 for a complete system. That’s one flat price, not a per-vent quote that grows once the tech is inside.
Full System Cleaning With Camera Inspection
We start with a camera inspection, because you should know what’s actually in your ducts before anyone cleans them. Then we set up negative pressure with HEPA filtration so loosened debris goes into the vacuum, not back into your living room. Then we run agitation tools through both supply and return sides. Then we clean the blower motor and air handler. Then we show you the before-and-after photos.

Return-Side Restoration
Many Wilmington homes have undersized returns that collect more than their share of debris. A supply-side-only cleaning misses the side of the system that’s often dirtiest in older homes here. We clean both, every time, as part of the flat price.

Trusted Brands We Service in Wilmington
We work on systems built around Honeywell, Aprilaire, and Guardsman filtration products, and we carry common replacement filters and components for Wilmington homes so you aren’t waiting on a parts order. Our cleaning fleet runs Rotobrush rotary brush systems and Nikro HEPA vacuums.

You shouldn’t need a second appointment just to finish a first one.
Common Air Duct Cleaning Problems We See in Wilmington Homes
- Return ducts choked with renovation debris. We handled a two-story in the Silver Lake area where the second-floor registers were barely moving air. Camera inspection showed the return duct was choked with construction debris and drywall dust from a prior renovation, so we set up negative pressure with HEPA filtration, ran agitation tools through the supply and return ducts, and cleaned the air handler and blower motor to restore airflow. The homeowner got before-and-after photographs of their own ducts at the end, and the flat price we agreed on before starting was exactly what they paid.
- Undersized returns in older capes and ranches. Homes near the town center often have original returns that were sized for heating only, not modern AC. These collect debris faster and show the worst airflow loss when dirty. Supply-side cleaning alone never fixes them.
- Long supply runs with many small registers. Wilmington ranch layouts often stretch duct runs across the whole footprint. Per-vent pricing turns that into a punishing quote. A flat price per system treats a 12-vent ranch and a 20-vent colonial the same way: honestly.
- Blower motors caked with dust. When the blower is dirty, the whole system underperforms even after the ducts are clean. We open and clean the blower motor and air handler as part of every full system cleaning in Wilmington.
Pricing for Air Duct Cleaning in Wilmington, MA
A typical residential full system cleaning in Wilmington runs $450 – $850. That includes camera inspection, supply and return cleaning, blower and air handler cleaning, and before-and-after photos. Commercial jobs run $900 – $2,500 depending on square footage and access. What affects price: the number of systems (a forced-hot-air furnace plus central AC is one system; a house with two separate air handlers is two), the accessibility of the ductwork, and whether there’s construction debris or animal intrusion. We never charge per vent. The price you agree to is the price you pay. Call (737) 727-2314 for a free estimate, and you’ll get a written number before anyone starts.

FAQs About Air Duct Cleaning in Wilmington
Most Wilmington homes benefit from a full cleaning every 3 to 5 years. Homes with pets, recent renovations, or occupants with allergies may need it more often. If you haven’t had it done in a decade and you have original ductwork, you likely have debris in the returns that’s quietly restricting airflow. Call (737) 727-2314 and we’ll camera-inspect before recommending anything.
We charge one flat price per system, agreed in writing before we start. No per-vent pricing. Wilmington capes and ranches often have long runs with many small registers, and per-vent quotes punish exactly those homes. The number we hand you before work begins is the number you pay.
We camera-inspect the ducts, set up negative pressure with HEPA filtration, agitate the supply and return sides with rotary brushes, clean the air handler and blower motor, and document everything with before-and-after photos. The process takes 3 to 5 hours for a standard single-family home in Wilmington. You get proof the work happened, not just a receipt.
