to get a room from 80 to 79 its easier on the system then 61 to 60

no shit

 

your question

 

was does it cost more to go from 71 to 70 than --------- 74 toi 73

 

no obviously with air coming in via cracks and air leaks, sure it is. But that is insignificant

 

The point

is if your thermostate is set at 75 or 70 the temp of the air the AC is producing and mixing into your room is the same, so the cost to cool that air is the same

 

AC units don't put out varing temps

Kk

Im saying the cost to run your ac stays the same per min its running.

 

Obviously a colder room cost more than a warm room

 

you said in post 2 it was the same cost, its not. even 73-71 then 71-69 has a different cost. ppl who run their ac's constantly at 65 are wasting a ton of energy

Yes. But that's not directly hitting his question on the head.

 

His goal temperatures add in a new element.

 

The further you are away from the outside ambient temperature, the more work the system will have to do. So even though those degrees from 75 to 73 are the same size as 73 to 71, they require different amounts of work from the A/C system.

Insignificant? It’s extremely significant.

 

And the temp coming out wouldn’t be the same either.
