Most new homes today are tightly sealed, and for good reason: A tightly sealed home prevents heated and cooled air from escaping and increases energy savings. Even older homes subject to drafts can be effectively sealed. However, the technology that has allowed homes to reduce the amount of heated or cooled air that escapes has also created conditions for less-than-ideal indoor air quality. If you or a family member has concerns about indoor-air pollutants, such as mold, an ultraviolet light system might be just what you need.

UV lights emit rays that target a specific class of pollutants, biological organisms such as mold and bacteria. These UV systems are generally installed within your home’s HVAC equipment, near the indoor coil. As the air passes through the light, the UV rays are able to zap pollutants. UV lights are effective, because they are able to break down the cells at the cellular level. If you’ve ever had a bad experience with mold growth, you know that it will reproduce quickly; it’s almost unstoppable. But UV lights target microorganisms’ DNA and render them unable to reproduce, effectively ridding the air of these contaminants.

Not only will your indoor air be cleaner, but the UV lights help to prevent buildup on your HVAC equipment’s indoor coil. When subject to buildup, dirty coils can significantly affect the efficiency of your systems.

In order to get a system that produces effective results, consider these factors:

• The UV system’s bulb’s ability to last over time. Some lower-quality bulbs will lose their intensity quickly.
• The temperature at which the bulb will operate efficiently.
• How long air is exposed to UV light. A quick pass through the UV rays won’t allow the system to target the pollutants.

For effective, targeted action against indoor contaminants, consider an ultraviolet light system. The experts at Jon Wayne Heating & Air Conditioning would be happy to help you select and install one. Feel free to contact us anytime.

Our goal is to help educate our customers about energy and home comfort issues (specific to HVAC systems).  For more information about an ultraviolet light system and other HVAC topics, download our free Home Comfort Resource guide.
