Indoor Air Quality Services in the Greater Raleigh Area

Installing a UV light in an HVAC system is quoted after a brief in‑home assessment because system layouts and device options vary by home. The visit lets a technician match the right UV solution, confirm safe placement, and plan wiring so the unit runs reliably. In practice, a clean‑coil UV can deliver strong results with little airflow impact, but the mounting point must avoid direct UV on nearby plastics. We install these systems for many homeowners in the Hillsborough area and provide free install estimates for indoor air quality system installations.

Your final price typically depends on:

• UV configuration (coil lamp vs in‑duct purifier, single vs dual lamp)
• Location and access to the air handler or duct (attic, crawl, closet)
• Electrical needs (adding a switch/outlet and proper circuit protection)
• Optional accessories (sight‑glass, safety interlock, manufacturer kits)

For the most accurate quote, schedule an on‑site visit before purchasing any equipment. <br/> Updated: 2026-03-09 <br/> Need help in Hillsborough, NC? Call (919) 823-4266 or book online.

Yes—most UV air purifiers can be repaired by replacing the UV bulb, which is a normal wear item. The most common cause is a burnt-out lamp reaching its hour limit, often signaled by a service light. If a new bulb does not light, the issue may be the ballast (power module), a door safety interlock not closing, or a failed power supply. A technician can test these safely and advise whether a small part repair makes sense or if the unit is near end-of-life. Our team services homes around Bahama and the Triangle with UV air scrubbers, HEPA filtration, and full IAQ support.

When to act and what to check:

• Turn off power and be sure the purifier’s access panel clicks shut on the safety switch.
• Install the exact replacement bulb; avoid touching the glass; then reset the UV change timer.
• If the breaker trips, there’s buzzing, or bulbs fail early, have the ballast and wiring tested.
• Replace the unit if the housing is heat-damaged or corroded.

Always power down the HVAC and purifier before opening any housing. <br/> Updated: 2026-03-30 <br/> Need help in Bahama, NC? Call (919) 823-4266 or book online.
