How quickly can Florissant residents expect Indoor Air Quality pros to respond?
- 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 a permit or inspection required to install in-duct UV‑C lights in Florissant homes?
- Possibly. In-duct UV‑C installations may trigger an electrical or mechanical permit in Florissant, depending on wiring changes and mounting methods. Installers who reference the 2018 IECC in their quotes typically note required inspections. Ask the contractor to list permits they will obtain and to show inspection sign‑offs after completion.
- What signals show a contractor has real experience with UV‑C and combined filtration systems?
- Experienced installers cite diagnostic steps, such as measuring coil cleanliness, static pressure, and airborne particle counts. They can demonstrate manufacturer familiarity and offer installation photos from past jobs. Ask whether they run a post-install verification test and provide a written maintenance plan for UV bulb replacement and filter changes.
