UV Light Systems – Frequently Asked Questions
Is UV light safe for children and pets?
An HVAC UV-C system must be installed so that people and pets cannot be exposed to the operating lamp. The lamp is enclosed inside the HVAC equipment, and access panels must remain closed during operation. Professional installation and compliance with the manufacturer's instructions are essential.
PRT Cool Service, Inc. can help evaluate a suitable UV system for your HVAC equipment. Request an appointment to discuss your options.
Is it safe to look at a UV light?
No. Never look directly at an operating UV-C lamp or expose your skin to it. UV-C exposure can injure the eyes and skin. Do not open the equipment to check the lamp while it is energized. Have a qualified technician disconnect the appropriate power sources before inspection or maintenance.
Why does the UV light stay on when the air system is not running?
Some UV systems are designed to operate continuously to help control microbial growth on directly illuminated HVAC surfaces, even when the blower is off. The operating schedule depends on the specific model and its installation. Follow the manufacturer's instructions for your system.
Can I upgrade my Blue-Tube UV system with a different lamp?
Replacement options depend on the exact UV system model, power supply and approved lamp part number. Do not assume that all Blue-Tube UV, UV-X or other Fresh-Aire UV lamps are interchangeable.
A qualified HVAC technician can identify your model and confirm which manufacturer-approved lamp and replacement interval apply before making a change.
My UV lamp still glows after its replacement date. Do I need to replace it?
Yes. A UV lamp can continue producing visible light after its germicidal output has declined. Visible light alone does not confirm that the lamp is providing its intended UV performance.
Follow the replacement interval specified for your particular lamp. Different models use different lamp service lives. We can help identify the correct replacement and schedule.
Will a UV light system eliminate mold inside walls or insulation?
No. An HVAC UV lamp does not treat hidden building materials. Its effect is limited to areas receiving an adequate UV dose, which depends on the system design, placement and exposure time.
Moisture sources and contaminated or damaged building materials require separate evaluation and corrective work. A UV system does not replace moisture control, filtration or regular HVAC maintenance.
Fresh-Aire UV systems are not intended to diagnose, treat, prevent or cure disease.
