The EPA says typical home UV lights have limited effect on bacteria and mold. We have no reported prices, so we do not quote a cost.

The EPA's guidance starts with something other than a device: the most effective ways to improve indoor air are to reduce or remove pollutant sources and to ventilate with clean outdoor air, and filtration supplements those. For a central system the EPA suggests a filter rated at least MERV 13 or as high as your system can accommodate (EPA air cleaner guide).
On UV, the EPA is specific and cautious. Ultraviolet germicidal irradiation lamps may destroy viruses, bacteria and some molds on moist HVAC surfaces such as coils, drain pans and ducts, but typical home units have limited effectiveness, and dead mold spores can still cause allergic reactions, so UV may not reduce allergy and asthma symptoms (EPA on UV and mold). It adds that research has not shown UV light removes gases effectively, and that UV lamps without adequate lamp coatings may emit ozone, a lung irritant (EPA air cleaner guide).
A professionally designed and well-maintained HVAC UV system can effectively kill the virus that causes COVID-19, but not by itself, and UV technology not designed for indoor air disinfection can expose eyes and skin to hazardous radiation (EPA on HVAC UVGI). In a house, that means: consider a UV coil light only for a documented growth problem on the coil, and have a licensed professional install it.
Simplified drawing, not to scale. Real systems vary: the indoor unit can sit in an attic or closet, the ducts can run in the attic or under the floor. Original illustration, not a photo.
Ask any salesperson for the model, the lamp's ozone certification and the replacement schedule, and ask what problem the light is meant to solve. If the answer is general air quality, the EPA says source control, ventilation and filtration come first, and that is cheaper. We cannot quote a price, so ask what problem the light solves before you compare prices.
The free steps are the EPA's: ventilate, control sources and change the filter, using the rating your system can accommodate. If the AC leaks or the pan has standing water, our drain page covers the moisture cause of mold.

Look for moisture first: a clogged drain, a wet pan or a humid house. The EPA says to keep AC drip pans clean and drains unobstructed, and not to run an HVAC system you know or suspect is contaminated with mold (EPA mold and moisture guide).
