Full System Cleaning in Alpharetta, GA

Full System Cleaning in Alpharetta, GA

Full system cleaning means every part of your ductwork gets cleaned, not just the main trunk lines. In Alpharetta, that means the supply ducts, return ducts, registers, grilles, the blower motor, the evaporator coil, and the drain pan all get attention in one visit. A full system clean typically runs from $450 to $900 for a standard single-family home in the Alpharetta area, depending on square footage and the number of vents. At Hollis Air Duct Alpharetta, the price is written down before any work starts, and it does not move at the door. Call (762) 769-7145 for a free estimate.

What separates a full system cleaning from a quick vent wipe is what happens inside the equipment. Most of the dust living in your HVAC system isn’t sitting in the first few feet of duct near the register. It’s packed into the return side, caked on the blower wheel, and layered across the evaporator coil where moisture makes it stick. When those components stay dirty, the air moving across them keeps picking up and carrying dust back into the house, no matter how often you change the filter. That’s why we clean the entire system, not just the visible parts. If you want a broader look at what this involves, our Air Duct Cleaning in Alpharetta page covers the full scope.

Roy Castellanos runs this location, and he’s built the way we work around a simple standard: a written price before the job, a written guarantee after it, and a crew that shows up inside the window, uniformed and background-checked. You’ll find the same expectation across every job we do, from residential duct cleaning to a full system clean in a five-bedroom home off Providence Road.

This page explains what full system cleaning includes, when you actually need it, what it costs in Alpharetta, and what the 365-Day Done Right Promise covers if something isn’t right. If you already know you need it, call (762) 769-7145 and we’ll get you on the schedule.

When You Need Full System Cleaning

Here are the situations where we see full system cleaning make the biggest difference in Alpharetta homes:

• Dust returns within days of dusting. If you wipe down a shelf on Saturday and by Wednesday there’s a visible film again, the dust isn’t coming from the shelf. It’s coming from the vents. A full system clean addresses the source, not the symptom.
• Your home was renovated recently. Alpharetta has plenty of homes built in the 1980s and 1990s getting kitchens and bathrooms redone. Drywall dust from renovation gets pulled into the return side and settles across the coil and blower. Standard filter changes won’t remove it.
• You can’t remember the last time anyone looked at the ducts. The general recommendation is every 3 to 5 years, but in a humid climate like Georgia’s, the coil works harder and collects more. If it’s been longer than that, there’s a good chance buildup has made the system work harder than it should.
• Someone in the house has allergies or breathing issues. Dirty ducts don’t cause allergies, but they do keep particulate circulating that makes symptoms worse. A full clean reduces the load the system keeps throwing back into the air.
• Airflow feels weak in one or two rooms. Often that’s a return pull problem caused by accumulated debris on the blower wheel, not just a closed damper. A full system clean restores airflow and often quiets the system down in the process.
• You just moved in. You have no idea what the previous owner’s habits were, whether they ran the system without a filter, or what’s inside the ducts. A full clean gives you a known baseline in a home you’re just learning.

One home in the Windward area we cleaned last spring hadn’t been touched in fourteen years. The return side alone produced four full vacuum canisters of gray dust, a mat of pet hair, and what we’re fairly certain was a 2016 birthday party’s worth of glitter. The homeowner told us the upstairs had stopped holding temperature in August. After the clean, the temperature differential between floors dropped to 2 degrees.

Our Full System Cleaning Process

Here’s exactly what happens when we do a full system cleaning in Alpharetta, start to finish. No mystery, no shortcuts, and you’re welcome to watch any part of it.

1. Walk the system and write the price. We count the vents, measure the system, check access to the air handler and returns. You get a written price before we touch anything. If the job needs more than we quoted, that’s on us, not you.
2. Seal and protect the work area. We lay down corner guards on walls, drop cloths on the floor, and seal off registers so the dust we dislodge doesn’t move through the house while we work.
3. Connect negative-air extraction. We hook up a Nikro negative-air machine to the system and seal it in place. This creates a vacuum inside the ductwork, so every particle we knock loose during cleaning gets pulled to the machine, not pushed into your living room. Plain English: the ducts are under suction the whole time. Nothing escapes into the house.
4. Agitate the duct interiors with the rotary brush system. We run the Rotobrush system through both supply and return lines. The rotating brush knocks loose the caked-on dust and debris, and the vacuum pulls it out continuously while the brush is working.
5. Clean the equipment, not just the ducts. This is the part most companies skip and the part that actually matters. We open the air handler and clean the blower wheel, the evaporator coil, the drain pan, and the housing. A clean coil transfers heat better, drains properly, and stops feeding moisture into dust buildup. Clean blower wheel means quieter operation and better airflow.
6. Final walkthrough and the written promise. We replace the registers, wipe everything down, and walk you through what came out of the system. Then we hand you the 365-Day Done Right Promise in writing: if anything we cleaned fails to hold for a full year, we come back and make it right at no charge, including the second visit.

We use filtration products from Honeywell and Aprilaire when the job calls for upgraded media or filter recommendations, and Abatement Technologies equipment where containment matters. These are commercial-grade tools, not hardware-store rentals. Roy ensures every tech on the crew is trained on running them by The Garrison Code: show up inside the window, price it in writing, do it by the book, leave the site cleaner than we found it.

Full System Cleaning Pricing in Alpharetta

A full system cleaning in Alpharetta typically lands between $450 and $900 for a single-family home. The spread comes down to a few factors: number of vents, number of systems (many larger Alpharetta homes have a separate upstairs unit), accessibility of the air handler, and how long it’s been since the last cleaning. Here’s the breakdown:

• Single system, 8 to 12 vents: $450 to $600
• Single system, 12 to 20 vents: $550 to $750
• Two systems (upstairs/downstairs): $800 to $1,100
• Add-on dryer vent cleaning: $89 to $129 when booked with a full system clean
• Coil and blower deep clean (if heavily caked): included in full system clean, not billed separately

What affects the price in Alpharetta specifically? Older homes in neighborhoods like Crabapple and the 30004 zip carry duct systems added or modified over decades, which means more access work. Homes built in the last five to ten years, around Halcyon or just north of downtown, tend to have newer, easier-access systems. If your air handler is in a tight attic with limited access, that adds labor time. If it’s in a finished basement with a clear mechanical room, it’s faster.

The price you’re quoted is the price you pay. No add-on surprises when the tech is inside. No “your coil needs a special clean” upcharge. The coil clean is part of full system cleaning, period. The quote covers the entire system as described, and it’s in writing before the machine gets turned on.

We also keep the estimate free. If you call (762) 769-7145 and describe your system, we can give you a solid range over the phone and then lock the exact number when we walk the job. You decide before anything starts.

Why Full System Cleaning Matters More in Alpharetta’s Climate

Alpharetta summers run long and humid. Your air conditioner pulls moisture out of the air as it cools, which means the evaporator coil is wet for a good chunk of the year. That wet coil grabs and holds any dust that makes it past the filter, and once it’s caked on there, it’s not coming off with a can of spray from the hardware store. A dirty coil reduces the system’s ability to cool, which means longer run times, which means higher power bills in July and August.

In the spring, Alpharetta’s pollen season is aggressive. Pine pollen and oak pollen get pulled through the return side and settle in the ductwork. Running the AC for the first time in May pushes a lot of that back into the house. The homeowners who call us every spring are usually the ones whose full system clean from a few years back is holding up, and they want it refreshed before allergy season peaks.

Filtration matters here too. When we finish a full system clean, we can talk to you about media filters from Honeywell or Aprilaire if your current setup isn’t doing much. But the filter only works if the system behind it is clean. A nice filter on a dirty coil is like putting new tires on a car with no brakes. The frame might look right, but the machine still isn’t doing its job.

Full System Cleaning vs. Basic Duct Cleaning

A basic duct cleaning brushes out the main lines and calls it done. Full system cleaning opens the system up. Here’s the difference in plain terms:

• Basic: Supply and return ducts brushed and vacuumed. Registers wiped. That’s usually it.
• Full system: Everything above, plus the blower wheel, blower housing, evaporator coil, drain pan, and the interior of the air handler. The parts that actually touch air after the filter.
• The reason it matters: If your coil and blower are dirty, cleaning only the ducts means clean air moving over a dirty coil, picking up dust immediately, and re-depositing it in the ducts and the house within months. You paid for a clean that won’t hold.

We don’t offer a “basic” clean. Every air duct cleaning we do is a full system clean, because a partial job doesn’t hold and doesn’t meet The Garrison Standard. When you call for Air Duct Cleaning, this is what you get.

What the 365-Day Done Right Promise Covers

Here’s the guarantee in plain English, the same way we hand it to every customer in writing:

• What’s covered: Every component we clean during a full system clean. Ducts, registers, blower, coil, drain pan, housing.
• How long: 365 days from the date we finish the job.
• What happens if something fails: You call us. We come back at no charge and make it right. The second visit is included. No arguing, no forms, no negotiation.
• What’s not covered: New contamination from something outside our control, like a home renovation that happened after our clean or a leak that introduced new water into the system.

We put this in writing because Roy started this company in 2004 with a simple observation: most people don’t get burned by bad duct cleaning because they don’t know what they’re looking at. They get burned because the company disappears the moment the truck pulls away. A written promise that covers a full year eliminates the disappearing act.

What Our Customers Ask Before Booking

These are the real questions we get on the phone, from homeowners in Windward, Crabapple, Halcyon, and everywhere else in Alpharetta. Short answers, no spin.

How long does a full system cleaning take?

Plan on 3 to 5 hours for a single-system home, 6 to 8 for two systems. We’d rather take the time to open the air handler and clean the coil properly than rush a job and hand you a clean that won’t hold.

Will there be dust in my house during or after?

No. The negative-air setup keeps the ductwork under suction while the brush works. Dust goes into the extraction machine, not your living room. We put down drop cloths and seal off the work area, and we wipe every register and surface we touch before we leave.

How often should full system cleaning be done in Alpharetta?

Every 3 to 5 years for most homes. Homes with pets, larger families, recent renovations, or someone with severe allergies may benefit from every 2 to 3 years. We’ll tell you honestly if your system doesn’t need it yet.

Do you clean dryers too?

Yes, and we recommend it on a different schedule, every 12 months. If you’re booking a full system clean and haven’t had your dryer vent done in a while, we’ll bundle it. Call (762) 769-7145 for pricing on both.

Can I get a quote before you come out?

Yes. Call us and describe your home, the number of vents, and whether you have one system or two. We’ll give you a realistic range, then lock the exact number in writing when we walk the job before any work begins.

FAQs – Full System Cleaning

How much does full system cleaning cost in Alpharetta?

Full system cleaning in Alpharetta costs between $450 and $900 for a standard single-family home, depending on the number of vents, whether you have one or two HVAC systems, and how accessible the air handler is. You get the exact price in writing before any work starts. Call (762) 769-7145 for a free estimate.

Can you do full system cleaning the same day I call?

We carry a live-answered phone line 24/7 and we work hard to accommodate same-day or next-day service in Alpharetta whenever the schedule allows. If we can’t make it today, we’ll tell you exactly when we can, and we’ll be there inside the window. Call (762) 769-7145 and ask what’s available.

Is full system cleaning worth the cost compared to basic duct cleaning?

Yes. A basic clean leaves the blower wheel and evaporator coil dirty, so the system re-contaminates itself within months. Full system cleaning opens the air handler and cleans the components that actually touch the moving air, which is why it holds for years instead of weeks. You pay once and the clean lasts.

What’s included in a full system cleaning that I won’t get elsewhere?

Supply and return ducts, all registers and grilles, blower wheel, blower housing, evaporator coil, drain pan, and the air handler interior. Plus a written 365-Day Done Right Promise: if the work fails within a year, we come back at no charge. Call (762) 769-7145 and we’ll explain the full scope and price before you commit.
