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.
Honeywell Vent Sanitizing: The New York City Owner’s Guide
We stock and install Honeywell UV air treatment systems and replacement lamps for existing Honeywell vent sanitizing setups across New York City. A typical installed Honeywell UV lamp replacement in NYC runs $285-$450 depending on the model, and most swaps take under an hour once we’re at the unit. You’ll usually know the lamp has failed because the system stops neutralizing odors it used to handle, or the indicator light on the control board goes dark. The bulb inside a Honeywell UV system has a rated service life, and once it’s spent, the unit is just holding a dead tube in your airstream.
Most New York City homeowners discover the failure this way: the musty smell comes back, the unit is humming but the air doesn’t feel as clean, or a seasonal maintenance check reveals the bulb has been dead for months. That’s the frustrating part about UV sanitizing: the equipment looks like it’s working when it isn’t. Tomas Reyes, our owner and lead technician, grew up in Woodside and has seen enough dead bulbs behind glowing indicator panels to know that visual checks alone don’t tell you anything.
Which Honeywell Models This Applies To
Honeywell’s UV treatment line falls under two main families: the UV100A series (UV100A1059, UV100A2009, and similar) and the newer UV2400 series. The UV100A units are the ones we most often find installed in New York City ductwork from the 2010s onward. These are 36-watt systems with a single lamp that mounts into the return or supply plenum. The UV2400 line is a larger, dual-lamp design built for bigger systems, and we see it more in newer condo buildings and single-family homes with oversized HVAC.
The compatibility gotcha to know: Honeywell changed lamp styles between the UV100A and the UV2400, and the bulbs do not interchange. If you have a UV100A1059, you need the RUV100A lamp (or a compatible 36-watt equivalent). If you have a UV2400, that’s a different lamp entirely. The lamp is roughly 15 inches long in the UV100A family, and the UV2400 lamps are shorter and paired. When you call us at (806) 606-6902, we’ll ask for the model number printed on the side of the unit before we bring a lamp out. That way we don’t show up with the wrong one. We also stock quality aftermarket equivalents for Honeywell lamps that match OEM specs at a lower cost, but we’ll always quote the OEM part first so you can make the call.
CleanRun Air Duct Cleaning is an independent service provider and not affiliated with Honeywell. We do, however, keep Honeywell lamps and ballasts on our trucks alongside parts for Lennox, Trane, and Carrier systems.
Signs Your Honeywell Vent Sanitizing Is Failing

- The power light is on but the UV lamp is dark. This is the most common one. The ballast can still draw power and light up the indicator while the bulb itself has burned out. The only way to verify is to remove the lamp cover and look inside (with the unit powered down, of course).
- Odors that used to disappear are back. A functioning Honeywell UV lamp breaks down volatile organic compounds that cause that stale, cooked-air smell in New York City apartment ductwork. When the lamp fades, the smell returns within a week or two.
- The lamp has been in service more than 12 months. Honeywell rates most UV100A lamps at 9,000-12,000 hours of effective output, which in a system running year-round is about one to two heating and cooling seasons. After that, UV output drops sharply even if the bulb still glows.
- You hear a faint buzzing from the ballast. A failing ballast often emits a low hum or buzz before it quits. If you hear this near the UV unit, the lamp may still be good but the power supply is on its way out.
- Visible dust or film on the lamp surface. The bulb sits in the airstream, and over time a film of dust and cooking grease (common in New York City kitchens with range hoods that recirculate rather than vent) coats the glass and blocks UV output. Even a working lamp won’t sanitize through a dirty sleeve.

AfterReplacement Cost & What’s Included
In New York City, expect to pay $285-$450 for a Honeywell UV100A lamp replacement, with the UV2400 dual-lamp jobs landing between $450 and $650. The range comes down to lamp cost versus aftermarket, whether the ballast also needs replacing, and how accessible your unit is. Some New York City mechanical closets leave about eight inches of clearance in front of the coil, which makes the job slower.
What you get from us, in writing, before any work starts: the lamp cost, the labor cost to access and replace it, and the exact total. Haven Standard Clause 1 is a written price delivered before a single panel comes off. No “we need to open it up first and see” pricing. We also photograph the old lamp and the new lamp installed so you can see the difference on the job record. The 365-Day Done Right Promise covers the labor and the part. If the lamp fails within the year, we replace it.
DIY or Call Us?

There’s a safe middle ground here. You can absolutely check the model number on the side of your unit and look through the viewing port (if installed) to see whether the bulb is glowing. What you should not do is reach into the plenum and unplug a live UV lamp without cutting power at the breaker and verifying it’s dead. UV-C light will damage your eyes and skin in seconds, not minutes. That’s the part where DIY goes wrong, and it’s not worth the hospital visit to save a service call.
The ballast also stores voltage, so even with the breaker off, a charged ballast can bite. If you’re comfortable with electrical lockout and have a multimeter, you might handle a straightforward lamp swap. But if any of that sentence made you pause, call us at (806) 606-6902 and we’ll be out. The photo tells you what’s in there. Everything else is just paperwork.
FAQs
In New York City systems that run air conditioning from May through September and heat from October through April, a Honeywell UV100A lamp typically delivers 12-18 months of effective sanitizing before UV output drops below the level that does meaningful work. Manufacturer ratings assume ideal conditions; our real-world replacement cycle in NYC is about 14 months on average. Call (806) 606-6902 and we’ll check your specific unit’s hours if the model tracks them.
A ballast can sometimes be repaired if it’s a simple wiring or capacitor issue, but in practice we replace ballasts rather than repair them. The lamp itself cannot be repaired once the mercury vapor inside is depleted. We’ll show you the failed part before we swap it, so you’re never paying for a replacement based on a verbal diagnosis.
Most Honeywell UV lamp replacements in New York City take 45 minutes to an hour, including power-down verification, lamp removal, new lamp installation, and a function test with the access panel replaced. If the ballast also needs replacing, add 30 minutes. We’ll give you the window before we arrive.
We stock Honeywell UV100A lamps, UV2400 lamps, and matching ballasts on our service vehicles. If you have a less common Honeywell model, we can usually have the exact part in hand within one to two days. Call (806) 606-6902 with your model number and we’ll confirm stock before we schedule.
