New owner concerned about possible respiratory infection

I just want to say thanks to everyone that has replied so far. I will increase the temp as suggested, I tried taking pictures but none of them showed the affected area with any detail. His nostrils are already looking less red with the reduced misting, (slightly, doing my best with what I have) increased temp, and changed substrate. I'm hoping to move him to a bigger tank soon with a larger under tank heater and bigger basking and night bulbs as well as a larger ceramic heating element. I've also bought an automated mister I just need the proper power strip to be able to regulate it. Until then however I have to work with what I got. I've noticed my room itself is a little cold so also increasing the ambient room temperature.

If anyone has other suggestions on cheap ways to increase his heat and stabilize his humidity while I am getting his new habitat set up I would be very grateful.

I have 1 humidity gauge and 2 thermometers, one on each side of the tank. I set up a zoo med fog machine on a timer to help with the humidity but it isn't doing much. And no I do not yet have a thermostat power strip.

Basically i've discovered ALL the things I've bought so far are crap. I just went out and got a new exoterra cage I was able to get a great deal on it and I plan on having an entire new set up by the start of December including: 50 gallon tank (exoterra), automated mister (exoterra), a night and basking light, as well as 2 ceramic heating elements and an under tank heater all plugged into a exoterra humidity and temperature control station.

I'd buy all of it now but I'm waiting for a sale at the end of the month at my local pet store. (20% off everything store wide) I'd love to purchase it all now but I just cant afford to lose that much money.

For now I'm just trying to keep my current set up habitable long enough to finish the new tank. I increased the ambient temperature of the room, and with the addition of a second night bulb I've been able to raise his night time temperatures up to healthy levels (85 on the hot side and 75 on the cool side again these are NIGHT TEMPS)

His nostrils are already looking better.

However, he really doesn't seem to like the fogger. I'm not sure if it's just because it's new but he puffs at the fogger when he's close to the exit tube and it's on. I know the fog isn't hot or anything and i'm fairly sure it can't harm him. Has anyone else had their snake react this way to a fog machine?
