The metal used in most ducts in air conditioning systems is highly resistant to damage caused by UV rays and does not wear out or become brittle over time, unlike plastic or other composite materials. Research has demonstrated that installing germicidal UV lights in the air controller can reduce the amount of mold and bacteria in a test home by 97%, as well as decrease the amount of airborne flu virus by 90%. UV lights are effective at eliminating substances such as bacteria and mold, but they don't get rid of dandruff or dust. If factors like these cause allergies, there are other HVAC system upgrades you can do to feel better, such as installing an air purifier. Spiral sterilization is the most common type of UV light for HVAC systems because it is less expensive than air sterilization and has similar efficacy.
HVAC UV lighting improves indoor air quality and airflow by eliminating particles such as mold and bacteria. However, it is recommended to replace a Carrier spiral UV lamp every 9000 operating hours or every year. In addition to making breathing easier, UV lights help HVAC units operate more efficiently and are less likely to be damaged. HVAC UV lights purify the air that circulates through the air conditioning system and eliminate contaminants such as bacteria and germs. Since UV lights only kill germs when the device is turned on, it is recommended to turn on the system for a few hours after installation. UV lights are an excellent way to improve the performance of your HVAC system.
They help reduce allergens, improve air quality, and increase efficiency. Installing a UV light in your HVAC system can help you breathe easier and save money on energy bills. However, it is important to remember to replace the UV lamp regularly for optimal performance.
