AfterHow Much Does HVAC Cleaning Cost in Alpharetta?
HVAC cleaning in Alpharetta typically costs between $425 and $875 for a full-system cleaning of a 2,000 to 2,500 square foot home in 2026. That price includes the supply ducts, return ducts, air handler, blower assembly, and both coils. Most Alpharetta homeowners pay around $600 for a complete job done with negative-air equipment and rotary brush agitation, not a shop-vac and a prayer.
We know that range is wide. The spread comes down to home size, how many systems you have, how long it’s been since the last cleaning, and whether you’re in a single-story ranch near downtown Alpharetta or a two-story brick home off Rucker Road. You’ll get an exact written price before we start. It won’t move at the door. That’s the whole point of The Garrison Standard.
If you’re just looking for the short version: budget $450 to $650 for a standard single-system home in Alpharetta, and expect to pay more if you have two HVAC units, a finished basement, or ducts that haven’t been touched in a decade.
HVAC Cleaning Cost Breakdown (2026)
Here’s what you should expect to pay in the Alpharetta market in 2026. These are real working numbers based on what we quote daily for homes in Windward, Crabapple, Downtown Alpharetta, and the surrounding north Fulton corridor.
| Service | Typical Alpharetta Price Range | What It Includes |
|---|---|---|
| Basic air duct cleaning (single system, up to 10 vents) | $325 – $450 | Supply and return duct cleaning, no coils or blower |
| Full HVAC system cleaning (single system, up to 14 vents) | $425 – $650 | Ducts, blower assembly, evaporator coil, return plenum |
| Full HVAC system cleaning (larger home, 15 – 20 vents) | $550 – $875 | Everything above plus additional runs and branches |
| Two-system home (upstairs and downstairs units) | $750 – $1,200 | Both systems cleaned, all vents and return drops |
| Dryer vent cleaning (add-on) | $95 – $150 | Full run from dryer to exterior termination |
| Duct sealing (add-on, per job) | $350 – $700 | Mastic sealing of accessible joints and connections |
Those numbers assume a routine cleaning. If you’re in a home off Old Milton Parkway that’s had three shedding dogs and the last cleaning was during the Obama administration, the job takes longer and the price goes up. By the same token, a well-maintained townhome near Avalon with a single five-ton system will land at the bottom of the range.
Every quote we give includes the same things: negative-air containment while we work, rotary brush agitation of every run we can reach, and a written breakdown of what’s included before we put a ladder up.
What Affects HVAC Cleaning Pricing in Alpharetta
Nothing about Alpharetta pricing is random. Here are the factors that actually move the number.
- Number of HVAC systems. A two-story colonial built in the 1990s on the east side of GA-400 usually has two units. A rancher off Haynes Bridge Road often has one. More systems, more coils, more labor.
- Vent count and duct runs. Alpharetta’s housing stock runs from 1980s split-levels to new construction in Avalon and Halcyon. Older homes often have longer, more complex duct runs. A 20-vent home takes noticeably longer than a 10-vent home, and the price reflects the difference.
- Access to the air handler and coils. Alpharetta’s attics get brutally hot from May through September. If your unit is in a tight attic crawlspace off the hall ceiling, the tech is working in 120-degree heat. That’s time, and time is money. Closet-mounted units in newer homes are faster and easier to reach.
- Condition of the ducts. Alpharetta’s humidity and pollen load mean ducts here collect more than dust. If there’s visible mold, heavy construction debris, or a prior renovation left drywall dust caked in every run, the job goes from routine to deep-cleaning territory.
- Existing duct leakage. If the ducts have never been sealed, the air handler is pulling unfiltered air from the attic. That means the system is dirtier than it should be, and the cleaning takes more passes. We’ll tell you if you need duct sealing, and we’ll quote it separately, in writing.
- How long since the last cleaning. NADCA, the trade association that sets the air duct cleaning standard, recommends every 3 to 5 years. If you’re at year 12, expect the first quote to be honest about the condition inside your ducts.
How to Save on HVAC Cleaning
There’s a right way and a wrong way to save money on duct cleaning in Alpharetta. The wrong way is hiring someone who charges $99 and shows up with a Shop-Vac and a squeegee. The right way is getting a fair price from a company that uses real equipment and stands behind the work.
Here’s what actually helps keep your cost down:
- Change your filters on schedule. A 1-inch filter in an Alpharetta home during pollen season needs changing every 30 to 45 days. A dirty filter means a dirtier blower and coil, which means a longer cleaning.
- Have the dryer vent cleaned at the same time. If we’re already at your home with the negative-air machine running, adding a dryer vent takes 30 minutes, not a separate trip. It’s the cheapest time to get it done.
- Keep your vents and returns clear. Furniture pressed against return grilles, rugs over floor registers: it all reduces airflow and makes the system work dirtier, faster.
- Don’t wait until the system is clogged. The longer you wait, the more heavy the buildup. A cleaning at year 4 is faster and cheaper than a cleaning at year 9.
- Ask for the written quote before anyone starts. We always provide one. If another company won’t put the price in writing before work begins, that’s your signal to move on. You’ll also avoid the classic “your ducts are worse than we thought” mid-job price bump.
We give free estimates over the phone. Call (762) 769-7145 and you’ll get a real human who can give you a practical price range for your Alpharetta home before we ever walk through the door. If you want the exact written number, we’ll schedule the visit and hand it to you before any work starts.
What Actually Happens During an HVAC Cleaning
You should know what you’re paying for. Here’s how a proper HVAC cleaning works in a typical Alpharetta home, and why the price looks the way it does.
We use the negative-air method. That means we hook a HEPA-filtered vacuum unit to the duct system, which puts the entire ductwork under negative pressure. Dust and debris that gets loosened gets pulled toward the vacuum, not pushed into your living room. Then we run a rotary brush system through each duct run to agitate and dislodge what’s stuck to the walls. The vacuum captures it before it ever reaches your air.
The reason this matters in Alpharetta specifically: this area’s humidity means dust here sticks. It cakes onto duct walls, especially in the return side of the system where air from the house gets pulled back toward the filter. A brush that just spins in place won’t get that. You need agitation plus negative air pulling at the same time, and you need a tech who knows what a properly cleaned duct looks like when they scope it.
After the ducts, we clean the components that actually matter for your air quality: the blower assembly, the evaporator coil, and the return plenum. A coil caked in a half-inch of Alpharetta pollen and drywall dust won’t cool efficiently, and no amount of duct cleaning fixes a dirty coil.
Then there’s duct sealing, if you need it. We use mastic, not tape. Mastic is a paste that hardens into a permanent seal over cracks and gaps in the ductwork. It stops your conditioned air from leaking into the attic and stops attic dust and humidity from getting pulled into the air you breathe. In Alpharetta’s climate, where attic temperatures swing wildly from January to July, duct sealing is one of the highest-return things you can do after a cleaning.
How Much Does Dryer Vent Cleaning Cost in Alpharetta?
Dryer vent cleaning in Alpharetta runs $95 to $150 as a standalone service, and $75 to $100 when we’re already at your home for an HVAC cleaning. It takes about 45 minutes and ends with a verified airflow test at the exterior vent termination.
Lint fires are real. The U.S. Fire Administration tracks roughly 2,900 dryer fires a year, and the leading cause is failure to clean the vent. In Alpharetta, where second-floor laundry rooms are common in newer construction, a clogged vent can silently accumulate for years, and the run to the exterior can be 15 to 25 feet, much longer than the ventilation standards recommend without a booster fan.
We recommend having the dryer vent cleaned every 12 months, especially if you’re running multiple loads a week in a household with kids in school sports or a family that’s home all day. The cost is a fraction of what a lint fire costs.
How Much Does Duct Sealing Cost in Alpharetta?
Duct sealing in Alpharetta runs $350 to $700 per job, depending on how much of the ductwork is accessible and how many joints, boots, and plenum connections need mastic. In a typical Alpharetta home built before 2010, the return side is where we find the most leakage, because it’s pulling air from the attic, not from the house.
Think about what that means: when your return ducts are leaky, the air handler is sucking hot, dusty attic air into your system 24 hours a day. Even after a full cleaning, that attic dust is coming back in through the leaks. Sealing closes the loop. The system runs cleaner, longer, and the air coming out of your registers is actually the air you paid to condition.
We quote duct sealing as a separate line item, always in writing. It’s never a surprise add-on after the cleaning starts.
Why Alpharetta’s Climate Makes HVAC Cleaning Matter More
Alpharetta sits in a climate band where the HVAC system runs hard for at least nine months of the year. Summer highs top 90 degrees regularly from June through August. Winter brings rain and occasional freezing nights. For most of April and May, the whole city is wearing a yellow coat of pine pollen, and your HVAC system is breathing all of it.
What that means for your ducts: the system pulls air from inside the home, but it also pulls from wherever the ducts leak. In an older Alpharetta home with a vented crawlspace or an attic with poor insulation, you’re getting a steady diet of outside air, pollen, humidity, and whatever lives in the attic mixing into your supply air. We’ve pulled clumps of insulation and drywall dust out of duct systems in homes near Wills Park and Kimball Bridge Road that hadn’t been cleaned since they were built.
Add pets to that, because most Alpharetta households have at least one, and you have a recipe for ducts that look like the inside of a vacuum bag. A cleaning every 3 to 5 years isn’t an upsell; it’s maintenance, the same way you service the car you drive on GA-400 every day.
Is It Cheaper to Clean or Replace Ductwork in Alpharetta?
Cleaning is virtually always cheaper. Full duct replacement in Alpharetta runs $2,500 to $5,500 for a typical single-story home, and that’s before any drywall repair if the ducts are buried in ceilings or walls. Cleaning the same system costs a tenth of that.
The only times replacement makes more sense are when ducts are physically damaged, collapsed, or soaked with water from a roof leak or a failed AC pan. If the ducts are just dirty, which is what we see in 90 percent of the homes we clean in Alpharetta, cleaning with negative-air equipment is the right call.
If you’re not sure, we’ll tell you. We scope the ducts and show you what we’re seeing. If replacement is what you actually need, we’ll say so, and we won’t try to sell you a cleaning that won’t fix the problem.
FAQs – HVAC Cleaning Cost
How much does HVAC cleaning cost in Alpharetta GA?
For a standard single-system home in Alpharetta, expect to pay $425 to $650 in 2026. Larger homes with 15 or more vents run $550 to $875, and homes with two separate HVAC systems typically fall between $750 and $1,200. Call (762) 769-7145 for a written quote tailored to your Alpharetta home. Estimates are free and the price doesn’t move once it’s on paper.
Is HVAC cleaning worth the money?
In Alpharetta, with the pollen load, humidity, and year-round HVAC runtime, most homeowners see it as maintenance, not luxury. A dirty blower and coil run less efficiently, which means higher power bills and a shorter system life. A proper cleaning with negative-air equipment and rotary brush agitation removes what’s actually restricting airflow. At $425 to $875 every 3 to 5 years, it’s cheap insurance against a compressor replacement that runs $3,000 to $6,000.
How long does HVAC cleaning take?
A standard single-system home in Alpharetta takes 4 to 6 hours. Larger homes or two-system homes can run 6 to 8 hours. We’ll give you a time window before the job, and we arrive inside it. That’s part of The Garrison Code, and it’s not negotiable.
Can you clean HVAC ducts the same day?
We can usually schedule within 24 to 48 hours for most Alpharetta homes, and same-day appointments are sometimes available for urgent situations. Call (762) 769-7145 and ask. A live person answers, day or night.
Do you provide a written guarantee with HVAC cleaning?
Yes. Every HVAC cleaning we do in Alpharetta is covered by the 365-Day Done Right Promise. If the work isn’t right, we come back and make it right at no charge, including a free second visit. It’s written on every job, and it’s why we put the price in writing before we start.
What’s included in a full HVAC cleaning?
Our full cleaning includes supply ducts, return ducts, the blower assembly, the evaporator coil, and the return plenum. That’s what the $425 to $875 price covers. The dryer vent, duct sealing, or sanitization are separate line items, quoted separately and explained before you agree to anything.
