What puts more stress on an ac unit:

I currently sleep with the ac on 70. While I am at work I put the ac on 77. When I get home I bump it down to 70 and it takes it about. 2.5 hours to get to 70. The unit is running constantly for 150 mins.

Would it be better for the unit to keep the ac on 74 during the day which would probably only make
The unit run for an hour to get to 70.

If my question is not clear let me know and I’ll try to think of a different way to ask.

Brah! Are you serious? Your A/C running for a STRAIGHT 150 min?

If this is central air, your A/C is low on freon and the fan in your attic is probably broken.

A good central air A/C unit takes around 10-20 min to bring your entire house temp down from the 80's to the 70's. Your AC if in the attic put out a lot of heat to be running. THere is a fan up there that is suppose to siphon most of it out otherwise you get upward of 160 degrees in your attic that is heating up your home while your A/C is simultaneously tryin to make it cool, which in turn extend the cool time.

Your third option is that your A/C tonage is not correct for the size of your home.

Final option is that you have a lot of cracks in your home bleeding out the AC or the insulation in your wall is either all super old now or too thin to do the job properly.
