Indoor Air Quality Services in the Greater Houston Area

Installing a UV light in an HVAC system is quoted after an on-site inspection because total cost depends on the equipment selected and how your air handler or ductwork is set up. The scope can vary from a simple coil-sterilizing lamp to a more advanced, in-duct solution, and labor changes with access and wiring needs. Abacus offers UVC germicidal lamps (three times more powerful, two-year lamp life, lifetime warranty on electronics) and homeowner-adjustable odor control options, with solutions integrated by licensed HVAC technicians. Our team regularly installs these systems for homeowners in the Cypress area, and zero-down financing is available for indoor air purification, with VIP members receiving discounts on qualifying services.

Key factors that set the installed price:

• Access to the air handler or supply plenum; tight attic spaces can add labor.
• Single versus dual-lamp coverage for coil and nearby plenum areas.
• Adding an oxidizing UVV odor-control module versus UVC only.
• Need for a new electrical tap or service switch at the unit.

Schedule a short evaluation so we can size the lamp correctly and provide a firm written price before any work begins. <br/> Updated: 2026-03-14 <br/> Need help in Cypress, TX?

Yes—most air purifiers with UV can be repaired by replacing the UV bulb, and Abacus installs UVC germicidal lamps with a two-year lamp life. The most common cause of a nonworking UV stage is simply a spent lamp; if a new lamp won’t light, the issue is usually the power module or wiring. Our UVC germicidal lamp electronics carry a lifetime warranty, and we also service in-duct options like the REME HALO® and whole-home HEPA units. We handle these IAQ repairs and replacements as part of our HVAC services across the Fulshear area.

• Replace the lamp if it has reached its rated life (about two years for our UVC lamps).
• If a new lamp does not light, have the electronics and wiring tested; lifetime-warranty electronics may be eligible for replacement.
• If air quality concerns persist, consider pairing UV with HEPA or polarized media filtration for full-home coverage.

Always switch off HVAC power before handling UV equipment to avoid eye and skin exposure. <br/> Updated: 2026-03-29 <br/> Need help in Fulshear, TX? Call (713) 812-7070 or book online.
