These 100% work! Although it depends on mold type as well as where installed. I did HVAC for many years and these became very popular during COVID. I have two installed in my heat pump system at home in MA. Please note, Although the UV lamp will bill certain types of bacteria and mold, it can only kill via line of site. Meaning anywhere the UV light does shine on, ie. where there’s a shadow when light is on, or other side of evaporator coil. My daughter gets symptoms for allergies every year, since I installed the UV lamp, they are Minimal at best.
If there is slight mold, another option is spraying coil cleaner (not bleach) onto the coils then rinse with water. This is a much less expensive option but does not kill any bacteria floating thru the air as it passes thru coil.
