incubator problems!

[Bartman]

My darn incubator keeps going crazy temperature wize. I think its because i keep it in my room and if the a/c stops then the temps sky rocket to about 88. These are leopard gecko eggs btw. I am trying to keep them at 82 for females, but it keeps going all over the place from 82 to 85 id say..I cant seem to keep it steady...well it was for the first week and then i dont knwo what happened..seems to be the weather change and all

What would you guys say is the best room to keep an incubator in (im using the inch of water, brick and rubbermaid with vermiculite and submersable heater method) My room has most the tanks in it so the room alone is at around 80..

Is like a washroom or open area in the house better? or a closet?

thanks! the eggs are still white so what does this fluctuation mean for the eggs? they look very healthy

and im so mad i didnt see my female lay eggs and they collapsed..i only have these 2 from her so far...
