Consumers use ultraviolet (UV) light products to sanitize toothbrushes, sterilize water, and remove germs from surfaces. UV lights also can clean the air and keep your HVAC system efficient. Before purchasing any for your home, read how UV lights work and where to install them.
What UV Lights in HVAC Systems Actually Do
Homeowners can purchase standalone, portable UV light units for installation anywhere in a home or office. They also can install UV lights in HVAC systems. Such UV lights come in two basic types:
- Air sterilizers. This UV light cleans air moving through the system. Installed in the air return, the light turns on when the fan starts running and turns off when the system is off.
- Air handler coil sterilizers. This UV light sits near the coils in the air handler and constantly runs to keep mold and other contaminants at bay. It is more cost effective than an air sterilizer but may not provide the same system-wide results.
Depending on your home and personal needs, each UV light type offers sterilizing benefits that may reduce maintenance activities and repair work. If you’re interested in both UV light types, consider starting with a coil sterilizer and then installing an air sterilizer after you see the results.
Benefits of HVAC UV Light Systems
Here are just a few of the benefits home and business owners can gain from investing in UV lights:
- Bacteria and virus elimination. For individuals highly susceptible to illness or for high-risk environments, built-in UV lights offer complete sanitization. Some systems can eradicate nearly all microscopic contaminants in an environment. Removing these contaminants will improve the smell and feel of the air in a home, too.
- Mold and fungi management. Mold can grow inside a system, causing health problems such as skin and eye irritations or respiratory illness. Removing mold can be expensive and time consuming. UV lights keep mold and fungi at bay.
- Peace of mind. Investing in UV lights means not worrying about a filter letting through some contaminants. The unit will sterilize all surfaces the light can reach and reduce the risk for contamination in other areas of the unit. The lights are cost-effective, running as little as $2.00 per month.
Where to Install UV Lights for Best Results
Depending on your needs and the system you choose, you may install the UV lights directly in the air handler. In addition to the air handler, you may choose to install them in the air return or in strategic areas throughout the ductwork. UV lights work best when placed around reflective surfaces and in conjunction with high-efficiency filters.
To properly install the light, invest in UV-protected HVAC components in areas the light may affect. Always read the manufacturer’s instructions regarding placement and mounting. Contact an HVAC professional for help if necessary. UV lights can significantly reduce health hazards in an indoor environment. A strategic installation will improve the overall health benefits.
