re: Anybody else’s wife have no idea how an AC thermostat works?

quote:

---

Go set your ac3 degrees below room temp, then measure air temp out of vent

Then set it 8 degrees below room temp and measure air temp out of vent

When the temp reading is the same 55 or so degrees come back to the thread and hand in your man card

he is technically not wrong. Youre saying that it wont instantly blow colder..it wont.

We know that all this does is keep the unit running until it reaches the new set point. But assuming that the heat loss in the home can be overcome by the AC capacity, the air will blow incrementally colder over time until the set point is reached. If you measured your register temperatures initially and then an hour or two later, it will be colder.
