Types of UV light systems and how they differ

Understanding the differences helps match the right system to your building and goals.

• In-duct UV systems

• Installed inside the HVAC ductwork, typically downstream of the coil or at the return plenum.

• Primary function: disinfect air moving through the ducts and irradiate surfaces exposed within the airflow.

• Best when paired with good filtration to inactivate microbes passing through the system.

• Coil-cleaning UV systems

• Mounted directly above or near the evaporator coil and drain pan.

• Primary function: prevent and reduce biofilm and mold on coil surfaces, keeping heat transfer efficient and reducing odors.

• Offers energy and maintenance benefits by preserving coil performance.

• Upper-room and standalone units

• Upper-room UV fixtures are ceiling-mounted to create a disinfecting zone above occupants while minimizing direct exposure.

• Standalone units are portable air disinfection devices suitable for rooms without centralized HVAC or for supplemental protection.

• Useful in occupied spaces like classrooms, reception areas, or meeting rooms when designed to meet safety and airflow criteria.

Site assessment and system selection process

A professional assessment ensures the system meets the specific needs of a Lower Ten Oaks property.

• Walkthrough and building audit
• Evaluate HVAC layout, coil accessibility, duct size and airflow, occupancy patterns, and areas prone to moisture or poor ventilation.
• Air quality and humidity review
• Identify sources of moisture and measure relative humidity and ventilation rates to determine complementary humidity control needs.
• Risk and goals clarification
• Decide whether the priority is coil protection, whole-system air disinfection, localized upper-room control, or a combination.
• System sizing and specification
• Select lamp type, quantity, intensity, and placement based on airflow velocities, exposure time, and surface geometry to achieve the intended microbial reduction.
• Integration plan
• Ensure electrical, mounting, and safety controls match local building standards and HVAC equipment constraints.

Professional installation steps and safety protocols

Correct installation protects occupants and preserves equipment warranties.

• Pre-install checks
• Confirm power availability, clearance, and compatibility with HVAC components.
• Installation steps
• Securely mount UV fixtures in ducts, over coils, or in upper-room locations using manufacturer-recommended hardware.
• Route and connect wiring to a dedicated circuit or controller, install switches and key interlocks to prevent accidental exposure.
• Shield sensitive components and install warning labels where required.
• Commissioning
• Verify lamp output, check ballast or driver operation, and confirm timers or motion/occupancy controls for upper-room systems.
• Document lamp hours and install safety signage for maintenance staff.
• Safety protocols
• UV-C radiation can harm skin and eyes. In-duct and properly shielded systems limit exposure. Upper-room and standalone units require placement, baffling, and controls to prevent direct occupant exposure.
• Technicians should use PPE during maintenance and follow lockout-tagout procedures for electrical safety.

Maintenance and lamp replacement schedules

Routine care keeps UV systems effective and extends HVAC life.

• Lamp replacement
• Traditional mercury UV-C lamps lose effective output over time; industry practice is to replace them every 9 to 12 months to maintain intensity.
• Some modern LED UV sources offer longer life and more stable output but still require scheduled checks per manufacturer guidance.
• Cleaning
• Quartz sleeves and fixture surfaces should be cleaned periodically to remove dust and mineral buildup that reduce UV transmission; frequency depends on local dust/humidity levels.
• Annual inspections
• Verify output with a UV meter or follow manufacturer service intervals, inspect wiring, ballast condition, and mechanical mounts.
• Record keeping
• Maintain a log of lamp hours, maintenance actions, and inspections to support warranties and compliance.

Expected efficacy against bacteria, viruses, and mold

UV-C inactivates microbes by damaging genetic material, but real-world performance depends on design and conditions.

• Mechanism
• UV-C damages DNA and RNA, preventing replication and effectively inactivating a wide range of bacteria, viruses, and fungal spores when they receive an adequate dose.
• Realistic outcomes
• Properly sized and positioned systems can produce high levels of inactivation for airborne microbes passing through a treatment zone and substantially reduce surface biofilm on coils.
• Effectiveness is influenced by airflow speed, exposure time, lamp intensity, duct geometry, and whether particles are shielded by dust or droplets.
• Combination strategies
• For comprehensive indoor air quality, combine UV disinfection with good filtration, ventilation, and humidity control. UV does not remove particulates or gases on its own.

Energy and cost considerations

Assess both upfront and lifecycle implications.

• Upfront costs
• Vary by system type, size, and complexity. In-duct and coil systems typically cost less than full-room upper-room installations when measured per protected area.
• Operating costs
• Include electricity for lamps and drivers, occasional cleaning, and annual lamp replacement for traditional bulbs.
• LED UV options reduce ongoing energy and replacement costs but may have higher initial cost.
• Savings potential
• Cleaner coils can restore HVAC efficiency, lowering energy consumption and reducing maintenance expenses. Reduced microbial maintenance needs can lengthen equipment life.
• Budgeting tip
• Factor in expected lamp replacement and inspection costs over the warranty period to evaluate total cost of ownership.

Warranty, compliance, and documentation

Ensure installations remain safe and supported.

• Manufacturer warranties
• Lamps, ballasts, and fixtures usually come with manufacturer warranties that may require professional installation and documented maintenance.
• Electrical and building codes
• Installations must comply with provincial and local electrical codes and building standards. Upper-room units should follow occupational health guidelines to prevent occupant exposure.
• Records and certifications
• Maintain installation reports, wiring diagrams, lamp replacement logs, and any performance test results to preserve warranties and satisfy future inspections.
