Yes — Mainstream offers ongoing maintenance for UV air filters, including bulb replacement, ballast inspection, fixture cleaning, and verification of output. UV-C bulbs lose effectiveness after about 9,000 hours (roughly one year of continuous use), so annual replacement is critical to keep the system performing.

UV maintenance includes

  • UV-C bulb replacement (annual)
  • Ballast and electrical connection check
  • Fixture and quartz sleeve cleaning
  • UV output verification
  • Coil mold/biofilm inspection

UV maintenance is included in our Mainstream Maintenance Plan, or schedule one-time service via indoor air quality.
