- Google rating. A strong rating floor reflects install quality and follow-through on bulb service.

How do Chesterfield residents pick a licensed Indoor Air Quality HVAC contractor and avoid surprises?
- 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.
- Is in-duct UV‑C installation regulated differently in Chesterfield, and what should I ask the installer?
- Local permit requirements vary, but the 2018 IECC is the baseline energy code in Missouri jurisdictions. Ask the installer whether a permit or inspection is required for in-duct UV‑C and request the model, lamp placement plan, and evidence of technician training for UV systems.
- What red flags indicate a contractor may not follow Chesterfield permit or code practices for IAQ work?
- Red flags include refusal to pull permits, reluctance to provide a written scope, no local permit history, and inability to cite applicable codes such as the 2018 IECC baseline. Choose contractors who document permit responsibility and who reference local inspection processes.
