EPA-Registered MediClean Disinfectant on Every Job

Most duct cleaning companies make you call, wait, and wonder. We built a different system — one that gives you a complete price estimate based on your home's square footage and HVAC unit count before anyone shows up. No callbacks. No surprises when the truck pulls in. Just a confirmed appointment that goes straight to our calendar.


We're a locally owned team based in Angier, NC, serving south Wake County, Harnett County, and the broader Triangle area. Owner Dan is on-site for most jobs, and you'll see the same crew every time — no contractors, no strangers.

What We Do — and How We Do It Differently

Every service we offer comes with before-and-after photo documentation as standard. You'll see exactly what was in your ducts, crawl space, or dryer vent — and exactly what we left behind. We use EPA-registered MediClean disinfectant, effective against SARS-CoV-2, on every job. That's not an upgrade. It's just how we work.

Residential and commercial duct cleaning with real-time pricing through our self-service quote calculator. Book online in minutes — no phone call required.

Mold Remediation

Mold in your home isn't a DIY project. We assess, contain, and remediate — with documentation at every stage. Crawl space mold is one of the most common problems we find in this region, and one of the most overlooked.

Crawl Space Encapsulation

A properly encapsulated crawl space controls moisture, reduces mold risk, and improves the air quality of every room above it. We'll assess your space and walk you through what it actually needs.

Dryer Vent Cleaning

A clogged dryer vent is one of the leading causes of residential house fires. Most homeowners don't know how long it's been since theirs was cleaned. We'll clear it out and show you what came out.

Indoor Air Quality Consulting

If your family deals with persistent allergies, unexplained odors, or respiratory issues at home, the problem may be in your air. We assess your home's IAQ and give you a clear picture of what's contributing.

The Face on the Website Is the Face at Your Door

We don't subcontract. We don't send different crews depending on the job. Owner Dan and the same core team show up every time — which means the people you see in our photos and read about in our reviews are the people walking into your home.


That consistency matters. It's why 67 homeowners left five-star reviews without being asked twice, and it's why we've held a BBB A+ rating since 2022.

    Serving South Wake County, Harnett County, and the Triangle

    We're based in Angier and do most of our work across the communities that surround it. If you're in Fuquay-Varina, Holly Springs, Garner, or Raleigh, we're already in your area regularly. We also serve Apex, Cary, Clayton, and surrounding Wake and Harnett County communities.


    Homeowners in Fuquay-Varina and Holly Springs make up a large share of our crawl space and mold remediation work — the soil and humidity conditions in this part of the Triangle create real moisture problems under homes that aren't properly sealed.

    Common Questions About Our Services

    • How does the online quote calculator work?

      Enter your home's square footage and the number of HVAC units, and the calculator returns a complete price estimate — no phone call, no technician visit required first. Once you have your number, you can book directly to our crew's calendar and receive a confirmed appointment.

    • Do you use the same crew on every job?

      Yes. We don't subcontract. Owner Dan is on-site for most services, and the same core team handles every job. The people you see in our photos are the people who show up.

    • What is MediClean and why does it matter?

      MediClean is an EPA-registered hospital-grade disinfectant we apply to duct systems on every cleaning. It's effective against SARS-CoV-2 and a broad spectrum of bacteria and mold spores. We use it as standard — it's not an upgrade or an add-on.

    • Do you handle crawl space mold remediation?

      Yes. Crawl space mold is one of the most common issues we find in south Wake and Harnett County homes, particularly in older construction without proper moisture barriers. We assess, remediate, and document the work with photos throughout.

    • How do I know air duct cleaning is worth it?

      We show you before-and-after photos on every job. You'll see exactly what was inside your duct system before we started and what it looked like when we finished. If the ducts were clean, we'll tell you that too — we're not here to sell you a service you don't need.

    • What areas do you serve?

      We're based in Angier and serve south Wake County, Harnett County, and the broader Triangle area — including Fuquay-Varina, Holly Springs, Garner, Raleigh, Apex, Cary, and Clayton. If you're not sure whether we cover your area, reach out and we'll let you know.
