What does an in-duct UV-C light actually do?

UV-C is most effective at keeping the evaporator coil and drain pan clear of mold and biofilm — a real benefit in humid climates where that buildup hurts airflow and air quality. CDC and ASHRAE endorse it for coil decontamination. It is not a standalone cure for allergens or odors, so treat 'kills 99.9% of airborne everything' claims with caution.

Single lamp or dual lamp, and how often do bulbs need replacing?

A single coil-mounted lamp handles coil sterilization; a dual-lamp air-stream system adds in-duct air treatment for a higher price. Either way the UV bulb loses output over time and is typically replaced every 12 to 24 months — budget for that recurring cost, not just the install.

What should I check when hiring a contractor for in-duct UV-C light installation?

Confirm the contractor understands in-duct UV-C placement, safety, and bulb replacement intervals. Request documentation showing the UV-C product model, expected lamp life, and whether the installer will shield occupants during service. Look for written maintenance instructions and a follow-up plan for bulb replacement and ballast checks.

What maintenance should Summerville homeowners expect after IAQ equipment installation?

Maintenance typically includes periodic filter changes, UV-C lamp replacement, and occasional fan or condensate-line checks. The installer should provide a maintenance schedule and a cost estimate for routine service. Regular upkeep preserves performance during Summerville's humid months and reduces the risk of mold or reduced efficiency.
