Your AC Drain is breeding slime. DRAINLight UV™ stops it in 2 seconds.

The Ultravation® DRAINLight UV™ mounts inside your air handler and floods the drain pan with germicidal UV-C light — inactivating the Zoogloea bacteria biofilm that clogs condensate and overflows, damaging your ceiling. Whole-home, chemical-free, ozone-free.

What's hiding inside your air handler.

A Florida AC pulls 10 to 15 gallons of moisture out of your air every single day. That water collects in a metal pan under your coil — the perfect 75°F dark, wet habitat for bacteria. Without disinfection, bio-growth seals the drain line in one or two summers.

Zoogloea

The white "drain slime" — the #1 cause of clogged condensate lines in our service area.

Biofilm

A thick bacterial layer coats the pan and seals the drain until water has nowhere to go but up.

Mold & Spores

Standing condensate releases spores into the airstream you and your family are breathing.

Ceiling Overflow

A blocked drain backs up through the pan and out the bottom of the air handler — straight into your ceiling.

How DRAINLight UV™ works.

UV-C light at the germicidal wavelength of 254 nanometers destroys microbial DNA on contact. Independent testing shows microbes can be inactivated in as little as two seconds of exposure. We mount the lamp inside the air handler, aimed straight at the water in your drain pan — so the slime never gets a foothold.

Drainlight UV

Step 1

We Mount the Light

An Alford tech installs the DRAINLight UV™ lamp using magnetic clips inside your air handler, aimed at the drain pan. No drilling, no rework, no electrician.

Step 2

UV-C Floods the Pan

The system runs continuously — germicidal light pours onto the condensate and destroys bacteria, viruses, and bio-film the moment they touch it.

Step 3

Drains Stay Clear

No slime, no clogs, no overflow, no ceiling damage. We swap the lamp every two Florida summers during routine maintenance. The system itself is covered for 10 years.

Used by hospitals since 1904.
Recognized by ASHRAE.

UV-C is a natural, environmentally-friendly disinfection method that involves no chemicals and creates no by-products. It has been used to disinfect air, water, and surfaces in food, pharmaceutical, and wastewater industries for nearly a century — and it is the only air-disinfection technology specifically recognized as effective by ASHRAE, the standards body for HVAC engineers.

1904

UV-C is first deployed in medical disinfection applications.

1930s

Adopted across food, pharmaceutical, water, and wastewater treatment.

Today

The only air-disinfection method specifically recognized as effective by ASHRAE for HVAC.

Why Florida homeowners install it.

No more panic calls in August.

The #1 emergency we run in summer is a clogged condensate line. DRAINLight UV™ prevents the clog from forming in the first place.

No drywall or mold remediation bill.

The average ceiling-overflow claim is $8,000 to $15,000 out of pocket. The unit pays for itself the first time it doesn't fail.

Lower power bills.

Even a few thousandths of an inch of bio-film on the coil insulates it — cutting HVAC efficiency 40 to 50%. UV keeps coils clean, when combined with an in-duct air purifier

That musty smell — gone.

"HVAC dirty-sock" smell is biology, not dust. UV-C eliminates the source instead of masking it with deodorizer, when combined with an in-duct air purifier.

Whole-house, silent, invisible.

Installs inside the air handler — no countertop appliance, no noise, no chemicals injected into the air you breathe.

Allergy relief.

Kills allergens at the source — the bio-growth inside the HVAC that would otherwise blow spores into every room of your home, when combined with an in-duct air purifier.

Frequently Asked Questions

Yes. The lamp is fully enclosed inside your air handler and never directly contacts the airstream you breathe. The system is UL 2998-certified ozone-free, and the magnetic UV shield blocks light leakage in every direction.

Roughly every 18,000 hours of run-time — about two Florida cooling seasons. We swap it during your normal maintenance visit for a flat $189 parts and labor.

In nearly every case, yes. DRAINLight UV™ is designed for any cooling-coil and drain-pan configuration. Magnetic clips and an adjustable shield make the install universal. If you already have an Ultravation UV system installed, ask us about the lower-cost EZ-Light-4-DUV upgrade kit.

The manufacturer covers the system for 10 years and the UV lamp for 1 year. Alford layers a 2-year labor warranty on top — so any service call inside that window is covered end-to-end.

The 24-volt system draws about as much power as a nightlight — pennies a month. In practice your bill drops, because clean coils run more efficiently and your AC doesn't have to work as hard to cool your home.

Under an hour for almost every Florida air handler. We arrive in the booked window, install the lamp, test the system, and leave the area cleaner than we found it.

The $150-off offer is reserved for existing Alford customers. If you're new to us, mention DRAINLight when you book your first service call and we'll roll the offer in.
