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 look for when hiring someone to install UV-C lights in an HVAC system?

Look for technicians trained in HVAC coil access and electrical safety, and ask for UV-C installation references. The installer should show how the UV-C placement targets coils or drain pans and explain safety protocols for lamp maintenance. Request documentation of lamp replacement intervals and any warranty terms the manufacturer advertises.

What diagnostic steps should a Greenville IAQ contractor perform before recommending equipment upgrades?

Contractors should start with a visual inspection, moisture and humidity readings, and baseline particulate or allergen testing. They should also check duct leakage, coil cleanliness, and ventilation rates. Expect a written diagnostic report that ties findings to recommended solutions and prioritized fixes. Use that report to compare bids and avoid unnecessary upgrades.
