HVAC UV Lights in Boise, ID

Keep Mold and Bacteria Out of Your HVAC System

The inside of your HVAC system is dark and, during cooling season, damp. That makes it a good place for mold and bacteria to grow. Once they settle on the cooling coil, your system can blow them through your home. An HVAC UV light helps stop that growth where it starts. Our team installs and services UV lights for homes in Boise, Meridian, Nampa, Caldwell and Eagle.

We have served the Treasure Valley since 1946. You get upfront pricing with no hidden fees. We explain your options and the cost before any work begins.

How HVAC UV Lights Work

An HVAC UV light uses ultraviolet light, called UV-C, to damage the cells of mold, bacteria and some viruses. Once damaged, they cannot grow or spread. The light is installed inside your air handler or ductwork, where you never see it.

Types of HVAC UV Lights

Coil Sterilization Lights

These lights shine on your cooling coil and drain pan all the time. Those parts stay wet during cooling season, so they are prime spots for mold. A coil light keeps those surfaces cleaner. This is the most common UV light we install.

Air Sterilization Lights

These lights sit in the ductwork and treat air as it moves past. Air moves fast, so the light has only a short time to work. They are best used with a good filter, not in place of one.

Benefits of an HVAC UV Light

Cleaner Cooling Coil

Mold and bacteria form a slimy film on the coil. That film blocks heat transfer, so your AC works harder. A UV light helps keep the coil clean, which helps your system run better. Coils with heavy buildup may still need our coil cleaning and repair service.

Fewer Musty Smells

A musty smell when the AC turns on often comes from growth on the coil or in the drain pan. A UV light helps reduce that source.

Support for Allergy and Asthma Sufferers

Mold spores can trigger allergy and asthma symptoms in some people. Reducing growth inside your system means fewer spores in the air you breathe.

Works With Your Other IAQ Equipment

UV lights do not trap dust or pollen. That is the job of a filter. For the best results, pair a UV light with air purification and filtration.

Signs a UV Light Could Help

  • A musty or mildew smell when the AC runs
  • Visible mold or slime on the coil or drain pan
  • A drain line that clogs often
  • Family members with allergies or asthma
  • A home that has had mold problems before

UV Light Installation and Service

1. Inspect Your System

We look at your air handler, coil, drain pan and ductwork. We check for signs of mold and find the best spot for the light.

2. Recommend the Right Light

We explain which type fits your system and goals. You get upfront pricing before we begin.

3. Install and Test

We install the light safely inside your system and make sure it runs as it should. UV light can harm eyes and skin, so the light stays sealed inside the unit.

4. Bulb Replacement

UV bulbs lose strength over time, even if they still glow. Most need replacement about once a year. We can replace your bulb during your AC tune-up or furnace tune-up.

Frequently Asked Questions about HVAC UV Lights in Boise, ID

Yes, when installed correctly. The light stays inside your air handler or ductwork. You should never look at a working UV-C bulb, so we make sure it is sealed and shuts off when the panel is opened, if your model offers that feature.
No. A UV light helps stop mold and bacteria from growing. A filter traps dust, pollen and other particles. You need both for the cleanest air.
Most bulbs need replacement about once a year. The bulb may still glow, but it loses strength over time. We can handle it during routine maintenance.
Often, yes. That smell commonly comes from mold on the coil or in the drain pan. A UV light helps reduce that growth. We will also check for other causes, such as a clogged drain line.
Some UV bulbs can make small amounts of ozone. Ozone-free bulbs are available, and we can recommend one for your home.
