Air Duct Cleaning in Alpharetta - One Flat Price, Before-and-After Photos

Trusted Air Duct Cleaning for Alpharetta Homeowners

Air duct cleaning in Alpharetta costs between $285 and $495 for a standard single-system home, depending on the number of vents, the age of the ductwork, and how long it’s been since the last cleaning. Most homes in Alpharetta need the work done every 3 to 5 years, though houses with pets, recent renovations, or allergy sufferers in the family often benefit from a shorter interval. We’ve been doing this work since 2004, and every job we run in Alpharetta gets a written price before any equipment comes off the truck.

That written price matters more than most homeowners realize. In this trade, a low teaser quote that balloons once the technician is inside the house is common enough that it has its own reputation. We don’t run that way. Roy Castellanos leads our crew, and The Garrison Code he enforces is simple: arrive inside the window, price it in writing before work starts, do the job by the book, and leave the site clean. If the work doesn’t hold up, our 365-Day Done Right Promise puts that in writing too. Call (762) 769-7145 for a straight answer and a free estimate.

Air Duct Cleaning Services

Air Duct Cleaning Services cover the full interior of your home’s duct system: supply and return ducts, registers, grilles, and the main trunk lines that move conditioned air through the house. In Alpharetta’s humid climate, dust, pollen, pet dander, and the occasional bit of construction debris from a renovation build up in these passages over time, which forces your HVAC system to work harder and recirculates fine particles through the living space. A full cleaning typically runs $285 to $495 for a standard Alpharetta home, and we give you that number in writing before work starts.

Source-Removal Cleaning

The negative-air method is the standard we use on every job. A Nikro or Abatement Technologies vacuum unit pulls the system into negative pressure while a Rotobrush rotary brush system agitates and dislodges buildup from the duct walls. What gets loosened gets pulled out through the vacuum, not blown around your house. That distinction is why we don’t use homeowner-grade tools or skip the containment step.

Register and Grille Cleaning

Most homeowners notice the registers first because that’s what they can see. We remove, clean, and reinstall every register and grille as part of the service, then wipe down the visible surfaces. If you’re dealing with Alpharetta’s spring pollen season, this step makes a difference you can see the same day.

HVAC Duct Cleaning

HVAC Duct Cleaning is the full-system approach to cleaning the passages that carry heated and cooled air from your furnace or air handler to every room in the house. It’s different from a simple vent wipe-down because it addresses the entire airflow path, including the Return Duct Cleaning side that pulls air back to be conditioned. Homes in Alpharetta with forced-air systems should have this done every 3 to 5 years, more often if there are shedding pets, recent drywall work, or visible dust around the registers. Expect to pay $285 to $495 for a complete single-system job, quoted in writing before we begin.

Return Air Ducts

The return side of the system is usually the dirtiest because it carries unfiltered air from the living space back to the equipment. We use the same source-removal approach here as on the supply side, and we inspect the return plenum for gaps or leaks while we’re in there. A clean return duct means your filter can do its job instead of being overloaded by what should have been trapped upstream.

Supply Air Ducts

Supply ducts carry conditioned air to each room, and any buildup here means you’re paying to heat or cool air that has to push through a layer of debris first. We clean the full supply run from the plenum to each register, checking airflow at the end of the job. If a run is damaged or disconnected, we flag it for air duct repair before it becomes a bigger problem.

Vent Cleaning

Vent Cleaning addresses the visible openings and immediate connections where air enters and exits each room. It includes the supply registers where conditioned air comes in and the return grilles where air goes back to the system. In Alpharetta homes, pet hair, candle soot, and dust from high-pollen seasons collect on these surfaces and restrict airflow even when the main ducts are relatively clean. Vent cleaning as part of a full duct cleaning service runs $285 to $495 for the complete system. For homes that only need surface-level vent cleaning between full services, we can quote that as a smaller job.

Supply Registers

The louvers on each supply register direct airflow and trap dust at the same time. Our technicians remove them, clean them properly, and adjust them so each room receives the airflow it’s supposed to get. That adjustment makes a real difference in rooms at the far end of the duct run, which is common in two-story Alpharetta homes.

Return Grilles

Return grilles pull air back into the system and collect a surprising amount of dust and pet hair over a year of normal use. We vacuum them with HEPA filtration and clean the duct opening behind them as far as we can reach. It’s a small step that improves airflow and air quality meaningfully.

Air Duct Repair

Air Duct Repair fixes physical damage in the duct system that leaks conditioned air into unconditioned spaces like attics, crawlspaces, and wall cavities. Disconnected joints, punctures from rodents, crushed flexible duct runs, and rusted out sections all fall under this service. In Alpharetta, where crawlspaces and attics are standard in older homes, we see more of these issues than most homeowners expect. Duct repair is priced after an inspection, but connecting a disconnected boot or sealing a visible hole typically runs $150 to $400, while replacing a full section of flexible duct can push the total into the $500 to $800 range. Everything is priced in writing before we start.

Duct Sealing with Mastic

Duct sealing mastic is the trade standard for a reason. It’s a paste that goes on wet and cures into a flexible, airtight seal, unlike tape that dries out and peels in attic heat. We apply it at joints, seams, and boots to stop conditioned air from escaping into spaces you don’t heat or cool. Done right, this is a permanent fix and part of what makes a full duct sealing job worth it.

Insulation Repair

Ductwork that runs through unconditioned attics and crawlspaces loses a lot of thermal energy when its insulation wrap is torn or missing. We inspect for this during every repair job and replace or restore insulation as needed. It keeps your conditioned air at the right temperature between the equipment and the room, which reduces the load on the system year-round.

Ductwork Cleaning

Ductwork Cleaning refers to the complete cleaning of the entire duct network, including the trunk lines, branch runs, boots, and connections that link your equipment to each room. It’s the broadest version of the service and the one we recommend for a Full System Cleaning when a system hasn’t been touched in five years or more or when you’ve just finished a renovation. Alpharetta homes built in the 1980s and 1990s often have sheet metal ductwork that has accumulated decades of buildup, and full ductwork cleaning makes a visible difference. A whole-system job runs $285 to $495 for most single-family houses.

Trunk Lines and Branch Runs

The trunk line is the main artery of your system, branching into smaller runs that serve individual rooms. We clean these with a rotary brush sized to the duct and a negative-air vacuum pulling the dislodged material out of the system. This is the most thorough approach available, and it’s the same method commercial buildings use.

Post-Construction Cleanup

Drywall dust, sawdust, and debris from a renovation settle into ductwork and keep circulating through the house for weeks after the contractor leaves. We recommend a ductwork cleaning after any project that involved cutting drywall or sanding floors. The time to do it is after the dust has settled, usually a week or so after the work is finished.

Air Duct Inspection

Air Duct Inspection is a visual and hands-on assessment of your duct system to identify leaks, blockages, mold, or damage that needs attention. We recommend it when a home has high energy bills without an obvious cause, rooms that never reach the right temperature, or musty odors coming from the vents. A standalone inspection in Alpharetta costs $95 to $150, and if you proceed with a cleaning or repair, that fee is credited toward the work. Every inspection comes with a written summary of what we found.

Leak Detection

Duct leaks in the attic or crawlspace are invisible to most homeowners. We check boots, joints, and connections for signs of air escape, using our hands and tools to feel for airflow where there shouldn’t be any. Leaking ducts can waste 20 to 30 percent of the air your system produces, which shows up directly on your utility bill every month.

Mold and Moisture Check

Alpharetta’s summer humidity creates conditions where moisture can collect in ductwork, especially in crawlspaces. We look for visible mold growth, water staining, and standing water during every inspection. If we suspect a problem that needs remediation beyond cleaning, we’ll tell you plainly and point you in the right direction, rather than trying to sell you a service that won’t fix the root cause.

Residential Air Duct Cleaning

Residential Air Duct Cleaning is the core of what we do every day in Alpharetta. Single-family homes here range from 1970s ranches with original sheet metal ductwork to recent builds with flexible duct runs, and each system has its own character. The goal is the same: remove the dust, pollen, pet dander, and debris that has accumulated inside the system so the air your family breathes is moving through clean passages. A complete residential cleaning runs $285 to $495 for the typical home, and the price is written down before we start.

Homes with Pets

Pet hair and dander get pulled through the return side of the system and coat the inside of the ductwork faster than most owners realize. We see it constantly in Alpharetta homes with one or more dogs, and the buildup is obvious when we get a camera inside. Homes with pets often benefit from a cleaning every 2 to 3 years instead of the standard 3 to 5.

Allergy-Sensitive Households

If someone in the house struggles with allergies or respiratory issues, clean ductwork is one part of the picture. Removing accumulated pollen, mold spores, and dust mites from the system reduces the amount of airborne particulate circulating through the house. We use HEPA filtration on our negative-air machines to make sure what we remove stays removed.

Commercial Air Duct Cleaning

Commercial Air Duct Cleaning serves the offices, retail spaces, medical suites, and light industrial buildings that keep Alpharetta running. Commercial systems are larger, run longer hours, and often serve more occupants, which means the buildup accumulates faster and the stakes are higher. We work around your operating hours to minimize disruption, and every job gets the same written price and 365-Day Done Right Promise as our residential work. Commercial pricing is based on building size, system configuration, and access, typically starting around $0.35 to $0.65 per square foot.

Office and Retail Systems

Rooftop units and long duct runs are the standard in Alpharetta’s commercial buildings, and they need regular cleaning to keep indoor air quality acceptable for employees and customers. We schedule around your business hours and keep the disruption minimal. Most office systems can be completed in a single visit.

Medical and Dental Suites

Medical facilities have higher air quality standards for good reason. We use the same negative-air source-removal method with HEPA filtration that we use on residential jobs, scaled up for the building. Documentation of the cleaning is available for your records, which helps when operators need to demonstrate compliance with facility maintenance plans.

Brands We Service

We work on every brand of ductwork and HVAC equipment in Alpharetta, but three names come up most often in our work with filtration and air quality: Honeywell, Aprilaire, and Guardsman. Each of those brands appears in homes where the owner has invested in better indoor air, and we know their equipment well enough to integrate our cleaning with the systems you already have.

Honeywell’s media cabinets and filtration systems are common in Alpharetta homes alongside Aprilaire humidifiers and Guardsman air purifiers. When we clean the ductwork, we make sure these components are seated, sealed, and working with the airflow instead of against it. Whether you have one of those brands or something else entirely, we service the system as a whole, and the guarantee attaches to all of it. Check out our home page to see the full scope of what we do.

Signs You Need a Pro Right Now

• Dust returns quickly after cleaning. If you dust the furniture and see a new layer within a day or two, the ductwork is likely recirculating particles. That dust is coming from inside the system, which means cleaning the house alone won’t fix it.
• Rooms never reach the right temperature. A duct leak or a blocked run means some rooms get air and others don’t. In multi-story Alpharetta homes, the upstairs often suffers first because the duct run is longer and the pressure drop is greater.
• You can see dust around the registers. Staining or dust accumulation on the wall or ceiling around a register indicates air is bypassing the duct and escaping into the framing. It’s a visible leak signal that inspection should catch.
• Energy bills climb without a change in usage. Leaking ducts and restricted airflow force the HVAC system to run longer to hit the thermostat setting. If the bill goes up and your habits haven’t changed, the ductwork is a reasonable place to look first.
• Musty odor when the system kicks on. The smell of damp or stale air from the vents suggests moisture in the ductwork or buildup that’s been sitting for a long time. That’s a cue to get an inspection rather than just replacing the filter and hoping the smell goes away.

Our Process, Step by Step

1. 1
   Written evaluation and quote. We walk the system, count the registers, check the equipment, and look at the access points. Before any work begins, you get a written price. That number does not change when the technician is inside your Alpharetta home.
2. 2
   System preparation and containment. We protect the flooring and furnishings around each register, and we seal off the system so what we dislodge is pulled into our negative-air machine, not pushed into your living space. The house stays clean during the job.
3. 3
   Source-removal cleaning. A Rotobrush rotary brush system agitates the interior walls of the ductwork while the negative-air vacuum pulls the loosened material out through HEPA filtration. This runs methodically through every supply and return run, from the trunk lines to the boots.
4. 4
   Verification and inspection. We inspect the main runs after cleaning to confirm the work is complete, and we look for damage, leaks, or mold that needs a follow-up conversation. What we find, we document and explain in plain terms.
5. 5
   Cleanup and final walkthrough. We leave the site as clean as we found it, reinstall every register, and walk you through what we did. You get the written guarantee, and you know exactly who to call if anything isn’t right.
