The Ultimate Defense: Professional UV Light Purification Service for a Healthier Home.

If your house feels dry every winter, you’re not alone. In Des Moines, furnaces run hard for months, and that heat pulls moisture out of the air fast. By January, a lot of homes start to feel it. Dry skin. Scratchy throats. Static shocks. Wood floors and trim that creak more than usual.

Portable humidifiers can help a little, but they’re usually a short-term fix. You’re refilling tanks, moving units from room to room, and still dealing with uneven results. A whole-home humidifier works differently. It connects directly to your heating system and manages humidity automatically across the house.

Greens Appliance, Heating & Cooling installs and services whole-home humidifiers for Des Moines homeowners who want something dependable and low-maintenance. Once it’s set up, it runs in the background and does its job without daily attention.

If you’ve ever noticed musty smells from your vents, allergy symptoms that linger indoors, or a system that never seems to stay clean, there’s a good chance biological growth is part of the problem. In Des Moines homes, moisture, basements, and long heating seasons create the right conditions for mold, bacteria, and other contaminants to build up inside HVAC systems.

Greens Appliance, Heating & Cooling provides UV light purification service for homeowners who want a cleaner, healthier indoor environment without chemicals or daily upkeep. These systems work quietly inside your HVAC equipment and treat air as it moves through. Most homeowners never notice them running. They just notice the air feels better.

The Science of Germicidal Protection (UVC Light)

UV light purification systems use UVC light.
It’s the same germicidal technology used in hospitals and labs.

That light targets the DNA of biological contaminants like mold spores, bacteria, and viruses so they can’t reproduce. As air cycles through the system, it passes by the lamp and is treated continuously.

Placement matters. We typically install UV lights in two spots.

One is near the evaporator coil. That area stays cool and damp, which is why slime and mold like to grow there. A UV light air purification system in this location keeps the coil cleaner and helps reduce odors before they spread.

The other option is the main supply plenum. Installed there, a UV light system treats airborne contaminants as they circulate through the house.

The system runs automatically whenever your HVAC system operates, most homeowners never notice it running. No chemicals. No filters to swap every week.

Why UVC Protection is Essential for Central Iowa Homes

Des Moines homes face a few repeat issues that make UV light for air purification especially useful.

Basements and seasonal humidity create ongoing mold risk. Even when humidity is controlled, growth can return around the coil. We usually see the biggest improvement right there. That’s where problems tend to start.

During winter, homes are sealed tight. Air gets recirculated for long stretches, which allows cold and flu viruses to move through the house. UV air sanitizers help reduce that recirculation.
The air keeps moving, but the biological load doesn’t.

Bacteria and microbial allergens can also build up inside ductwork and HVAC components. Filters catch particles, but they don’t stop growth. UV light air sanitizers addresses that gap.

Single Lamp vs. Dual Lamp Systems

Not every home needs the same setup.

Single lamp systems focus on coil sterilization. They’re designed to keep the evaporator coil clean and prevent slime and odor issues before they enter the air stream. For many homes, this is enough.

Dual lamp or plenum-mounted systems add air sterilization to the mix. These systems are often recommended for households dealing with allergies, asthma, or frequent illness.

Greens Appliance, Heating & Cooling looks at your furnace or air handler, how air moves through your ductwork, and your concerns before recommending a UV light purification installation. The goal is proper placement, not extra equipment.

Seamless Integration and Simple Upkeep

UV light installation is straightforward when it’s done correctly. Our technicians integrate the unit directly into the ductwork near the air handler or furnace, with minimal disruption.

The light stays enclosed inside the metal ductwork. There’s no exposure risk to people or pets.

Maintenance is simple but important. UV lamps lose germicidal strength over time, even if they still glow. Most need replacement every 9 to 12 months to stay effective.

Greens Appliance, Heating & Cooling provides UV light purification installation, maintenance, and repair. We service all major brands and handle common issues like failed lamps, leaky housings, or faulty humidistats without turning it into a bigger project than it needs to be.
