UV-C light is used inside HVAC equipment to neutralize mold, bacteria, and other microorganisms that grow on coils, drain pans, and internal surfaces, helping improve indoor air quality and system cleanliness.

UV-C light emits a specific ultraviolet wavelength that disrupts the DNA of microorganisms, preventing them from reproducing and spreading through the HVAC system.

Yes. When properly designed and installed inside HVAC equipment, UV-C light operates safely out of occupied spaces and does not expose building occupants to ultraviolet radiation.

UV-C lamps are typically installed near cooling coils, drain pans, air handlers, or other areas where moisture and biological growth are most likely to occur.

UV-C systems help prevent:

• Mold and microbial growth

• Dirty coils and airflow restriction

• Musty odors

• Increased maintenance caused by biological buildup

No. UV-C light complements filtration by neutralizing biological contaminants, while filters capture airborne particles. Together, they provide a more complete indoor air quality strategy.

Yes. By keeping coils cleaner and preventing biological buildup, UV-C systems help maintain airflow and heat transfer efficiency, reducing strain on HVAC equipment.

Most commercial UV-C lamps are rated for approximately one year of continuous operation. Regular inspection and scheduled replacement are necessary to maintain effectiveness.

Yes. UV-C light is particularly effective at preventing mold growth on damp surfaces such as cooling coils and drain pans, where mold commonly develops.

UV-C systems are commonly used in:

• Healthcare and medical facilities

• Office buildings

• Schools and universities

• Fitness centers

• Manufacturing and industrial spaces

• Warehouses and distribution centers

UV-C maintenance typically includes:

• Lamp inspection and replacement

• Output verification

• Safety checks and access review

• Periodic system performance evaluation

Yes. By controlling microbial growth inside HVAC equipment, UV-C systems can reduce odors caused by mold and bacteria that develop on coils and drain pans.

Engineered Temperature Solutions applies UV-C light based on HVAC layout, airflow patterns, and microbial risk areas, ensuring proper placement, safe operation, and long-term performance.

UV-C light is often recommended when buildings experience:

• Recurring mold or microbial growth

• Frequent coil cleaning

• IAQ complaints or odors

• Humid operating conditions

• High indoor air quality requirements

Yes. Engineered Temperature Solutions designs, installs, and services UV-C light systems for commercial and industrial facilities across Central Ohio, supporting cleaner HVAC operation and improved indoor air quality.
