  • UV Light and Your Indoor Air Quality

    We at NORTHSTAR Heating & Cooling believe in the importance of good indoor air quality (IAQ) to ensure the comfort and health of you and your family. UV lights can be used in your home to aide your air filtration system in destroying biological pollutants such as viruses, bacteria, allergens and molds that are airborne or growing on HVAC surfaces.

    How does it work?

    The UV light is installed in the air duct of an HVAC system. It is positioned downstream from the filter to radiate all the particles as they pass through the filter, before they pass through the cooling coil and out into your home. As micro-organisms flow through your HVAC system, the UV light reduces their viability and ability to reproduce. These micro-organisms become “deactivated” so they can no longer affect your indoor air quality. Your HVAC system circulates your home’s air several times a day. Each time air passes through, it is being disinfected by the installed UV lights.

    Maintaining UV Lights

    UV light air purifiers work at their optimal performance when used with a high-quality air filter. To ensure the best indoor air quality for your home, regularly change your air filters and perform routine maintenance for your HVAC system and UV lights. UV bulbs should be replaced and cleaned every year during annual HVAC maintenance.

    Benefits of UV Light Technology

    For years, UV lights have been used in places like clinics and hospitals to keep the air and medical surfaces clean and disinfected. While they may not cure all your indoor air quality problems, they can significantly improve the comfort and health of those sensitive to air quality. Research has shown that they are effective at deactivating indoor biological pollutants such as mold, mildew, viruses and bacteria that are airborne or growing on HVAC surfaces.

    Whether you are just considering UV technology or you have already decided to go ahead with the installation, call NORTHSTAR Heating & Cooling at 218-628-9276 to get started!
