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.
Aprilaire Coil Cleaning: The Sandy Springs Owner’s Guide
Aprilaire evaporator coil cleaning in Sandy Springs typically runs $340-$580 for a full system service, and we stock the compatible cleaning agents and tools for all current Aprilaire series. Most appointments are scheduled within 48 hours, with the coil accessed, cleaned, and photographed before we pack up. Homeowners usually realize something’s wrong when the upstairs never reaches set temperature, or they notice a sweet, musty smell right at the blower kick-on - both point to a coil that’s choked with biofilm and Georgia pollen paste.
Which Aprilaire Models This Applies To
We clean coils paired with Aprilaire whole-home dehumidifiers, air cleaners, and the humidifier lines installed on furnaces throughout Sandy Springs - specifically the 1800, 1850, and 1870 dehumidifier series, plus the 500, 600, and 700 humidifier families. The critical compatibility gotcha: Aprilaire’s newer 1850F uses a wider coil face (16 by 20 inches) than the original 1850 (14 by 17.5 inches), and the cabinet footprint differs enough that a technician who doesn’t measure first can damage fins trying to force access through the wrong panel gap.
Identification is straightforward if you know where to look. The model label sits on the front panel of the dehumidifier or on the bypass duct collar of a humidifier; the coil itself carries a separate part number stamped on the header rail. We carry OEM Aprilaire foaming cleaner (part 4837) and the fin-safe brushes sized for their tube spacing, but we also stock quality aftermarket equivalents from Guardsman that match the 0.006-inch fin gauge without the OEM markup. For systems still under Aprilaire’s 5-year parts warranty, we document the cleaning with before photos so any future warranty claim isn’t denied due to “maintenance neglect.” CleanRun is an independent service provider - not affiliated with Aprilaire - and we source parts through authorized distributors so warranty compatibility stays intact.
Signs Your Aprilaire Coil Cleaning Is Failing

- Uneven cooling upstairs. The coil sits in the plenum (the main air distribution box) above your furnace, and when its fins are packed with debris, airflow drops before it ever reaches the second-floor duct runs. We see this constantly in Sandy Springs ranch homes off Spalding Drive, where the original flex duct elbows already add static pressure.
- Sweet or musty odor at blower start-up. That’s microbial growth on the coil surface, fed by condensation that never fully drains in Georgia’s high summer humidity. The smell peaks in July and August when the coil stays wet between cycles.
- Ice formation on refrigerant lines. A dirty coil insulates itself, dropping the surface temperature below freezing and building ice that blocks airflow entirely. Left alone, this strains the compressor and can trip the system’s low-pressure safety switch.
- Water around the furnace base. The coil’s condensate pan overflows when algae and sludge clog the drain port. In Sandy Springs, we find this paired with a failed float switch more often than you’d expect - the switch was never installed or was bypassed by a previous owner.
- Humidifier or dehumidifier runs constantly without reaching set point. The coil can’t exchange moisture efficiently when fins are occluded, so the unit cycles longer, draws more power, and still leaves the house sticky or bone-dry depending on the season.

AfterReplacement Cost & What’s Included
| Service Level | Price Range | What’s Included |
|---|---|---|
| Standard coil cleaning (accessible, no disassembly) | $340-$420 | Coil foaming, fin straightening, drain pan flush, condensate line blow-out, before/after photo record |
| Deep cleaning (coil removal required) | $480-$580 | Full coil extraction, immersion cleaning, cabinet sanitizing, reassembly with new gaskets, full photo documentation |
| Coil replacement if cleaning fails | $890-$1,400 | New OEM or equivalent coil, installation, pressure test, system restart, 365-Day Done Right Promise |
The range depends on three factors we assess before writing the price: whether the coil is accessible through a standard panel or requires duct disassembly, how badly the fins are corroded (Sandy Springs’ acid rain years took a toll on pre-2015 aluminum), and whether the condensate drain needs rebuilding. We deliver one written price before any work starts, every time, under Haven Standard Clause 1. No per-vent add-ons, no “surprise - your coil is worse than we thought” mid-job. The 365-Day Done Right Promise covers the workmanship in writing, not as a verbal assurance.
DIY or Call Us?

There’s a safe middle ground and a hard stop. An owner can replace the Aprilaire filter media, check that the condensate drain line exits freely, and verify the humidistat or dehumidistat reads within 5 percent of a handheld meter. What you should not do: open the plenum, handle refrigerant lines, or use a pressure washer on the coil fins. The fins bend at 20 PSI, and a compromised coil becomes a $900 replacement instead of a $400 cleaning. The refrigerant loop is EPA-regulated; venting it is a federal violation, and the pressure can cause frostbite or eye injury.
We bring Nikro and Rotobrush negative-pressure extraction equipment to contain the mess, and we photograph every stage so you see what came out. The photo comes first. The invoice comes second. If you’re weighing a DIY attempt against the cost of a documented professional job, call (678) 904-9744 and we’ll put a written number next to whatever you’ve been quoted.
FAQs
Most need their first deep cleaning at 3 to 5 years, and annually after that if the home has pets, carpet, or sits near the pollen corridors along Roswell Road. Georgia’s humidity accelerates biofilm growth compared to drier climates, so the “every two years” rule from manufacturer literature rarely holds here. Call (678) 904-9744 for an exact assessment - estimates are free.
Corroded or split coils cannot be patched reliably; the refrigerant seal will fail. Fin damage up to 20 percent can be straightened and restored to adequate airflow, but beyond that, heat transfer drops enough that replacement is the only lasting fix. We document the fin count and corrosion level in our photo record so you can see the threshold yourself. Call (678) 904-9744 for a written second opinion on any replacement recommendation.
A standard cleaning runs 90 minutes to 2 hours; a deep cleaning with coil removal takes 3 to 4 hours. We schedule a full morning or afternoon block so the crew isn’t rushing the reassembly or skipping photo documentation. All CleanRun technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and Tomas Reyes reviews every photo record before it leaves the truck.
We stock Aprilaire 4837 foaming cleaner, Guardsman-compatible fin brushes, and the gaskets and hardware for coil removal on every service vehicle. For coil replacements, we pull from our distributor in metro Atlanta with next-day availability on most Aprilaire series; the 1850F wide-face coil sometimes requires 48 hours. We don’t start the clock on your job until the part is in hand and the written price is signed.
Ready to see what’s actually inside your plenum? Call CleanRun Duct Repair & Cleaning at (678) 904-9744 for a free, written estimate. We’ll show you the before photo before we say what it costs. Every job carries our 365-Day Done Right Promise, a Documented Photo Record of every duct run, and equipment you can verify - Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - named in writing on your scope sheet.
