Wow, this an odd one.
It sounds like the awning started the problems. The awning is on the 12v side of the house. It is unusual that a 12v fault would affect the AC side of things. The 12v side is protected by fuses and the 110v side by breakers like a house. I've found that tripped breakers are not always obvious. I'd suggest manually closing a breaker for one of the A/C appliances and resetting it to see if it starts.
It sounds like all 12v is off. Do you have a battery? Does it have a charge. You say DH has checked fuses, did he check with a VOM? I think there may be a fuse behind the panel that protects the 12v from the 110v. Someone will probably add more about this.
