I need some help with power in my home!

Definitely, as others said time to call in the electrician.

… If you're remotely handy and have some basic electrical knowledge, you can kill …

Electricians are called Sparkies in Australia… 😀

Gosh, I forgot about aluminum wiring.  If you have it, you definitely need an electrician to bring the connections up to code. The issue is AL with 120VAC circuits.  The 240VAC circuits are okay for AL due to the way they terminate.  

I rented a house with AL wiring one time, beautiful home, but one day it almost burned down due to AL wiring.  I walk away from any home for sale today if it has AL wiring.

Gosh, I forgot about aluminum wiring…

It is not uncommon in some copper wired homes to have aluminium or aluminum between the service tower and homes.
I am not sure what is running down from a pole, but I think that often steel.

Hence a Sparkie can figure out whether it is between the service and the house, or within the house.

Aluminium is not by definition ”out of code”… and the power company is not usually prone to pulling out the wire from the service point to the house.

Most power companies use aluminum wire from the transformer to the main service feeder wire. The problem with aluminum wiring throughout the house is it can loose a good connection over time with temperature changes it's called creep.
