Corinne,
UGH! I just happened upon this post. I totally know what your dealing with! I had installed HVAC in my tiny shop which was 650ft but between customers opening the door (even though my ac guy factored inthat and the sun hitting my shop) in Chicago it would get soooo hot!
I had a dog groomer two doors down and the hair blowing out would sufficate my unit. Then, the cases would over work so I would call a refrigeration guy to refill the freonand cleanthe ac unitsjust because it was overworked.
I had 2 federal chocolate cases and the heat and humidity would still cause condensation on the front of the cases and we left our ac units on 24/7.
If you keep the chocolate in the fridge long term your screwed, or in that "chocolate display" your still faced with condensation which sucks when you are trying to control quality of the product.
When we were faced with the electricity going out we left them in our bun racks that had covers sealed and didn't touch them! The ones in the case we tried not to open the doors and yes, there would be casualties but there is always someone willing to eat free ugly chocolate.
You may have to look in your area and get a regular climate controlled chocolate case which as I stated the exterior will have condensation but the product will be fine. I know, probably doesn't help your situation but I know what your dealing with!
Good luck and hang in there!
