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.

Are there local permit or code requirements in Huntsville for UV-C light or permanent air-purifier hookups?

Permits and code compliance depend on the equipment and how it connects to the ductwork or electrical system. Huntsville follows the 2021 IECC for residential work. Contractors should pull any required permits and verify installs meet the code and electrical rules. Ask the contractor which permits they will obtain and why.

How effective are in-duct UV-C lights for microbial control in Huntsville’s humid season?

In-duct UV-C lights can reduce microbial growth on coils and surfaces when properly sized and installed. They are most effective as part of a comprehensive plan that includes coil cleaning, humidity control, and filtration. Ask contractors for evidence of expected microbial reduction and maintenance requirements.

What maintenance should Huntsville homeowners expect after installing IAQ equipment?

Regular maintenance includes scheduled filter changes, UV-C lamp replacement per manufacturer guidance, periodic coil and drain pan cleaning, and annual system inspections. Dehumidifiers require drain checks and occasional service. Ask the contractor for a clear maintenance plan and recommended service intervals for each installed component.
