HVAC UV lightsGermicidal UV lights can be a key part of a whole-house ventilation and air quality solution. UV lights can significantly reduce concentrations of microorganisms in your home's air and inside your heating and cooling equipment. Unhealthy microorganisms commonly found in our homes include viruses, bacteria, dust mites, yeast and mold. As an article that appears in Applied and Environmental Microbiology states, fungi found on cooling coils and in duct systems often leads to hypersensitivity and health problems such as allergic rhinitis and asthma attacks.


These fungi and bioaerosols can be bad for your health and for your home comfort equipment. The same contaminants that cause lung discomfort and poor air quality also shorten the life of your heating and cooling system and affect its performance.

How do UV light systems work? Air cleaners equipped with ultraviolet lights are installed as part of your existing heating and cooling equipment. They emit ultraviolet rays that reduce concentrations of biological particles and microorganisms by penetrating cell walls and neutralizing the tiny organisms' ability to grow and spread. The lights work continuously even when your home comfort system is not running to kill organisms on the cooling coil and other surfaces.

Ideally, germicidal lights are part of an integrated system combining air purification, humidity control and ventilation to provide superior air quality for your home and family. By controlling the moisture level in your home, a dehumidification system helps keep mold problems from taking hold. If there is mold growth in your home, it’s important to clean up mold completely and fix the the problem's source otherwise your mold problem may return. For best results, combine an air cleaner with a dehumidifier as part of a whole-house ventilation system.
