UV Light FAQs

Do UV lights help with musty odors?

They can help reduce odor-causing buildup on coils and in the air handler when installed correctly.

Where is a UV light installed—coil or air stream?

It depends on the goal. Coil placement targets buildup at the coil/drain pan; air-stream placement supports broader air treatment.

How often do UV bulbs need replaced?

Most systems need bulb replacement about once a year (varies by model and runtime).

Can you repair an existing UV system?

Yes—GEM services most major UV/IAQ systems and can troubleshoot power, ballast, bulb, and wiring issues.

Will a UV light replace filtration?

No—UV complements filtration. We’ll recommend a setup that supports air quality without restricting airflow.
