15 amp fuse to 30 ?

I live in an older home and the electrical has been updated. My problem is now that it is summer I am running a window air conditioner and I am having problems with the breaker blowing when I try to use the vacuum cleaner. The breaker box has only a 15 amp fuse for the complete front room. That is used for TV, DVD, VCR, stereo, lamps ect. I was wondering if I could switch the 15 amp fuse for a larger amp like a 30? My way of thinking is the 30 amp fuse would be able to handle all the appliance and the air conditioner better then a 15 amp. But I'm not really that familiar with electrical issues and afraid it might cause some problems by doing this (like burning down the house ha ha). So if someone could help me by letting me know if this is possible I would appreciate.

can't just change the breaker from 15A to 30A w/o considering the wiriring.

make sure your line can handle 30A or it'll burn up!

Do NOT do that.
I'm not an electrician, but "like burning down the house" is exactly what could happen if you overload a probably a 14/2 wg wire circuit on a 15 amp fuse and put a 30 amp fuse on it.
If you have that many appliances and electronics in your front room, you need to run at least an additional circuit to it, preferably a 20 amp with 12/2 wg wire.
Consult a professional electrician, who will know your local electrical code, and can upgrade it safely for you.
Good Luck!

I confiscate those 30 A fuses all the time. I threw some away in a friends garage the other day. They were never meant to use that way and some panels wont accept them for just that very reason. I replaced a couple of panels that were actually fine in some migrant housing because every year I would find a box of 30's as they plug some yard sale junk in and the first thought is to up the fuse. At least with breakers they cant change them. Old farm buildings are full of them from pops using one when the table saw blows one. If it was a dedicated line it would be one thing but now the whole circuit is on a 30. Everytime I see one I thow them in the trash. Super dangerous especially when its installed where there was a 15 in the first place.

You need to run a dedicated circuit for the airconditioner. Do not replace the fuse with a 30.
