UV Light Installation in Hyrum, UT

Does your Hyrum home smell musty when the air conditioner starts?

A musty smell in a Hyrum home when the AC kicks on often comes from mold growing on the damp indoor coil, and a UV light installed by the coil helps keep that growth from coming back. The indoor coil, also called the evaporator coil, is the part of your central air that actually cools the air. It usually sits in a dark, closed box right above the furnace, and it gets wet every time the AC runs. That makes it an easy place for mold and slime to grow. A UV light is a lamp that gives off UV-C, a type of ultraviolet light. Aimed at the coil and the drain pan under it, the lamp helps keep those surfaces clean. We install and maintain UV lights in Hyrum, about 12 miles east of Brigham City in Cache Valley.

Warning signs a Hyrum home could use a UV light

A musty smell at the vents

The smell is strongest right after the system starts, then fades. That pattern points to growth inside the system rather than somewhere in the house.

Dark growth on the coil or drain pan

During a tune-up, a technician may spot black or green growth on the coil or in the pan underneath it. Cleaning removes it. A UV light helps keep it from returning.

The AC drain line clogs with slime

A slimy film in the drain pan can wash into the drain line and block it. Water then backs up around the furnace in summer.

The coil gets dirty fast

A coil that needs cleaning at every visit has a sticky film that grabs dust. Growth on the coil also blocks airflow, which makes the system work harder.

Common causes of mold and musty air in Hyrum systems

Condensation on the indoor coil

Cooling pulls moisture out of the air, and that moisture collects on the coil. Even in our dry summers, the coil stays wet while the AC runs.

A drain pan that holds water

If the pan or drain line drains slowly, a little water sits under the coil for days. Standing water and darkness are where mold gets started.

Long idle stretches

In spring and fall the system may sit off for weeks. A damp coil that sits still in the dark gives growth time to take hold.

Dust that feeds growth

Dust that gets past the filter sticks to the wet coil and gives mold something to live on. Hyrum gets its share of seasonal dust, so a good filter matters too.

What to expect when we install a UV light in Hyrum

We start by looking at your system: the coil, the drain pan, the filter and the drain line. If there is growth now, we explain how we would clean it, because a UV light works to keep a clean coil clean. We also tell you plainly if a UV light is not the right fix for what you are noticing.

You get your options and the price before any work starts. The lamp mounts inside the cabinet or duct near the coil and is wired to power. Many models have a small window that glows when the lamp is on. We show you how to check it and how to switch it off, since UV-C light can harm eyes and skin if you look straight at it. Last, we explain the upkeep: the bulb needs cleaning and periodic replacement to keep working.

UV light installation in Hyrum

Hyrum winters are cold, and Cache Valley inversions can hang over the valley for days. Homes stay closed up, and the same indoor air moves through the system again and again. A UV light helps keep the coil and drain pan in that air path clean. It does not filter smoke or dust, and it does nothing about radon, a gas that is a known risk in Cache County homes.
