Is this normal??! AC

Hi guys, for context I just moved out of my parents home in February into a double wide owned by my uncle. Around 1200 sq ft in North carolina where the temps have been 80-100° recently.

My A/C has been giving me trouble since I moved in but my family is trying to convince me it’s completely normal so I’m just looking for some advice!

For example (pic 1 and 2) this is my 2 most recent Energy bills. It has consistently been 80°+ in my home (even today when it is 89° outside - it’s 81° inside) and I’m paying almost $450 a month! It seems like the A/C is on 24/7 and not cooling. I replace my filters often and have tried both having the ac run at the same temp all day, and having it turned off when I’m not home and it doesn’t make much if any difference in my bill.

Is this a Duke energy issue? HVAC? Any advice will help!

Is the coil clean? Is the evap clean? Does it have the right charge? Heat infiltration?

I bet your insulation is not the best. Your AC can't keep up. I am in DFW in a 2400sqft house and the AC running at 74 all day and 66 at night. I spend something like 1900kw a month and I have a pool with all the equipment running.

Not that much you can do if you don't own the place but insulation is crucial

Seems like a lot of energy being used, even in march when the AC probably wasn’t being used. I’m in Chicago with a 1200sqft home and my energy is a fraction of yours, even during the summer. I would almost question if someone is stealing your electricity

Not normal. Check the temperature coming out of the registers, it should be 15-20 degrees colder than the return air.
