Air duct cleaning pricing is confirmed after an in-home assessment. The cost varies by home size, number of registers, duct condition, access, and whether you add services like duct sealing, insulation, or UV air sanitizers. Our Denver-area team serves Highlands Ranch, Aurora, and the metro. We offer whole-home IAQ solutions and can pair cleaning with filtration upgrades or humidity control. Clean or replace your air filters every 1–6 months to keep ducts cleaner. We recommend an annual inspection by our Bell team.

UV light installation pricing is confirmed after an in-home assessment. Final cost depends on the UV system selected (e.g., UV air sanitizer or Reme Halo), access to the coil or supply plenum, any new electrical needed, and duct condition. We offer $100 off a new Reme Halo air purifier through 2025-12-31. A technician will size the unit, review options, and provide a flat-rate quote before work begins in the Denver metro.

Home indoor air quality testing cost varies based on what needs to be measured and the tools or lab analysis required, and final pricing is confirmed after an in-home assessment. The biggest driver is scope: basic checks cost less than multi-pollutant testing with samples sent to a lab. We tailor recommendations to your home and may suggest filtration, purification, or humidity control if testing finds issues. We routinely perform IAQ assessments across the Denver metro, including Wheat Ridge, and adjust for Colorado’s dry climate and dust.
When getting quotes, ask what’s included:
- Pollutants tested (particulates, VOCs, biological samples, or combustion byproducts)
- Use of continuous monitors vs. one-time grab samples
- Number of sample locations and home size
- Reporting detail and follow-up consultation
Current promotions may reduce your upfront cost, including a free air quality assessment and discounts on in-duct purifiers and whole-house humidifiers. If you notice strong chemical odors or symptoms that worsen at home, schedule testing promptly.

Yes. If the UV bulb in your air purifier stops working, a technician can inspect the unit and, if the model supports it, replace the lamp and restore operation. Bell installs and services UV air sanitizers and other IAQ systems throughout Denver and nearby cities like Aurora and Highlands Ranch. Exact pricing depends on on-site diagnosis. We recommend an annual inspection by our Bell team.
Quick checks:
- Verify power to the air handler.
- Check the UV indicator light.
- Replace clogged air filters.
