are you speaking about something like an industrial chiller system or a geothermal heat pump?

If so, the answer would be yes sort of. Freon is a trademarked name that DuPont owns and it is a specific family of refrigerants. A system would have to use only a DuPont product to say it actually uses Freon. There are other manufacturers of refrigerants that are the same chemical compound. There are also refrigerants that are not called Freon, even by Dupont.

Yes they do use refrigerant. I have replaced quite a few water to air units to standard units. A lot of customers were unhappy with them. They tend to have scaling problems after a few years that affects heat transfer. Also, you have to figure out what to do with all the water. Some people run it to a pond or use it for watering. If you are on a well, your pump will be running constantly. Are you trying to replace an existing water to air unit?

I am in a condo, and there is a water cooling tower on the roof.

My air conditioner has been on all day, and can't get the condo below 80 deg. Cold air is blowing strong out of the vent nearest to the a/c, but the other vents don't have much coming out.

Could it just need more freeon, or do I likely have scale built up.

TIA
