Lights are designed to clean the air as it goes through the air handler of the AC system.

HVAC company has no $ incentive to do a mold test. It probably would show no mold and a basic mold test is around $300

You can buy a mold test from Amazon for $30 that comes with 5 petri dishes. You just swab the surface and put it in a petri dish. You can send the petri dish to a lab and they will do a professional test for $40.

A circulation fan should continue to run for a time after the cooling setting is satisfied. The goal is to clear all moisture from the air path when a cooling cycle is complete.

UV lamps placed near the evap coils(in the air handler) are gaining popularity. Check you tube. Any nearby wiring must be shielded from the lamp to prevent insulation deterioration.

Mine doesn't operate that way, and I am not aware of any system that has that option. The cooling cycle removes moisture from the air, so I don't understand how that function would provide any benefit. The heating cycle does operate the heating coil for a short time before the fan comes on to heat up the air in the HVAC plenum. It prevents cold air from being distributed into the house.

You live in Florida. There is mold everywhere. It is part of our everyday environment in the air and the soil. The presence of mold does not mean it needs to be eliminated or treated. Doing a home test for mold may well be positive but does not mean you should be buying a UV light to attempt to reduce the exposure.

There are unusual situations where mold needs to be treated, and UV is not the means of treatment.

Not saying it is a scam, but a very common method for AC companies to pad their wallet. Get a second opinion.

Good, this is the key for homes here:

Use an air conditioner or a dehumidifier to reduce the indoor humidity levels below 60%. If you have a central air conditioning system and need a dehumidifier to reduce relative humidity below 60%, you should have the air conditioning system examined for problems.

I have often wondered about HVAC systems being located in a hot and humid garage. Also, clothes washers in the garage in Florida the same thing. It seems to me they would be a natural breeding ground for mold.
Our system is in the house in a controlled environment which makes more sense I believe. Our band new Trane system is whisper quiet.

I would say it is a scam.

The sounds like a scam. I actually have my ac guy coming in the next hour for my annual cleaning. I’m going to ask him if that’s possible. Just for FYI when I had my air ducts cleaned up north the tech tried to bull**** me saying I had mold in my ducts and recommended something similar. I called my heating company and they came and checked and found no mold.

I offend wonder about this when HVAC systems are in stalled in a garage.

Isn't there heat and humidity sucked in during hot and humid days, or does
most return air come from in the house from the cold air return??

Most HVAC systems do not have an outside air intake. They operate on a 100 percent return air basis. I don't see any problem with the unit being installed in the garage.
