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.

AfterAprilaire Vent Sanitizing: The Johns Creek Owner’s Guide
We stock and install Aprilaire-compatible vent sanitizing systems in Johns Creek, with most jobs completed same-day and installed pricing running $340-$580 depending on your duct configuration and whether we’re pairing sanitizing with a full cleaning. The photo goes first. The price comes after. Homeowners usually discover their vent sanitizing isn’t doing its job when they notice musty air returning right after a standard duct cleaning, or when someone in the home with allergies sees no improvement despite new filters.
Which Aprilaire Models This Applies To
Aprilaire’s vent sanitizing line breaks into two series that matter for Johns Creek homes: the 1000-series units designed for single-zone systems up to 3 tons, and the 2000-series built for zoned or larger-capacity setups common in the two-story builds around Medlock Bridge and the Chattahoochee River corridor. The model number lives on a metal tag inside the access panel, not on the outer housing. If the tag reads 1910, 1930, 2910, or 2930, you’re in the right place.
The critical compatibility gotcha: Aprilaire changed its collar sizing between 2018 and 2020. Pre-2018 units use a 6-inch round duct connection; post-2020 units shifted to 7-inch oval to match newer IECC duct standards. We carry both adapter sets on our trucks. For OEM, we source direct from Aprilaire’s distribution network. For quality aftermarket, we use Guardsman-compatible housings that match the UV-C output spec at 253.7 nanometers, which is the wavelength that actually disrupts microbial DNA, not the decorative blue light some budget units emit. We will show you the spec sheet before we open the first panel.
Signs Your Aprilaire Vent Sanitizing Is Failing
- Musty odor returns within 48 hours of duct cleaning. The UV-C lamp has degraded below effective output. Lamps lose roughly 15% intensity per year even when the indicator light still glows; by year three in Georgia’s high-humidity climate, most are producing cosmetic light, not sanitizing dosage.
- Visible microbial staining at registers despite regular filter changes. The lamp may be cycling on and off due to a failing ballast, which delivers inconsistent UV dosage. In Johns Creek, we see this most often in homes with crawl space returns where summer humidity spikes above 75% RH.
- Allergy symptoms persist or worsen in specific rooms. The unit’s placement is wrong for the duct geometry, or the lamp arc length doesn’t match the plenum depth. A 16-inch lamp in a 24-inch plenum leaves dead zones where air passes untreated.
- Indicator light is on but the lamp housing is cold after 10 minutes of runtime. The lamp has failed open-circuit while the status LED, wired separately, still receives power. This is the most common silent failure we document in our photo records.
- HVAC technician notes “biological growth” on the evaporator coil during maintenance. The vent sanitizing system upstream isn’t delivering enough UV intensity to suppress coil fouling. In Johns Creek’s cooling-dominant climate, this accelerates efficiency loss and drives up summer power bills.
BeforeAfterReplacement Cost & What’s Included
In Johns Creek, installed Aprilaire vent sanitizing replacement runs $340-$580 for most residential systems. The lower end covers a straight lamp-and-ballast swap in an existing Aprilaire housing with good access. The upper end applies when we’re retrofitting a new mounting location, adapting to non-standard ductwork, or pairing the sanitizing with full negative-pressure extraction cleaning under Haven Standard Clause 1.
Every quote is written and agreed before work starts. What’s included: the lamp or full housing, electrical connection testing, UV intensity verification with a calibrated radiometer, and a Documented Photo Record of the installation location and surrounding ductwork. The 365-Day Done Right Promise covers the installation and electrical work; the lamp itself carries the manufacturer’s rated lifespan guarantee. We publish our license number on every estimate, and every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews.
DIY or Call Us?
There’s a safe middle ground here. A homeowner can check the indicator light, note the model number from the access panel tag, and verify that the unit is receiving 120V at the junction box with a non-contact voltage tester. What you cannot safely do: remove a UV-C lamp while powered, look directly at an operating lamp, or attempt to bypass the interlock switch that shuts the unit when the panel opens. UV-C at 253.7 nanometers causes photokeratitis, essentially a sunburn on your corneas, and the interlock exists because technicians have injured themselves ignoring it.
Beyond safety, the actual failure point is often misdiagnosed. A glowing indicator does not mean effective output. A new lamp in a failing ballast will degrade in months. We carry radiometers on every truck because the number that matters, microwatts per square centimeter at one meter, cannot be eyeballed. If you’ve checked the basics and the unit still isn’t performing, call (470) 326-1926. We’ll bring the meter, show you the reading, and give you a written price before we touch a tool.
FAQs
Expect 2.5 to 3.5 years of effective output in Georgia’s climate, shorter if the HVAC runs continuously in summer. The manufacturer rates lamps at 9,000 hours, but high humidity and frequent cycling reduce real-world lifespan. Call (470) 326-1926 and we’ll check your install date against our service records, or inspect the unit if we’re new to your home.
No. UV-C lamps are sealed glass tubes with a finite mercury charge; once the arc fails or output drops below 40 microwatts per square centimeter, replacement is the only option. We do not sell lamps for customer installation; the electrical and interlock requirements mean this is a technician-performed replacement under our warranty.
Most replacements take 45 to 90 minutes, including access, radiometer verification of the new lamp, and photo documentation. Retrofits or relocations in complex zoned systems, common in the larger homes near Autrey Mill Nature Preserve, can run 2 to 3 hours. We quote the full scope in writing before starting.
Yes. We carry lamps, ballasts, and housing adapters for both pre-2018 and post-2020 Aprilaire collar sizes, plus Guardsman-compatible equivalents. For less common configurations, our supplier in metro Atlanta delivers same-day. We also stock parts for Lennox, Trane, and Carrier systems.
