A short YouTube monologue (by Derek Cole) explaining why an air-conditioning unit running for a long period is not necessarily bad: the home aims to maintain a thermostat set point, so continuous operation can indicate it's maintaining temperature. Longer run times—often with slower fan speeds—improve dehumidification because air spends more time over the cooling coil, extracting heat and moisture. The speaker uses a car climate-control analogy to make the point.

Think about getting in your car and then driving to the store. How many times did you turn off the ac? Probably not ever. Your home's the same way. It's trying to keep that same temperature all throughout the day. So it's not going to stop running if it's on a set point it's trying to reach. Now. If it reaches that set point, then obviously it's going to turn off. But the unit running for a long period of time is not necessarily a bad thing. The longer the unit runs, the slower the fan speed, the better it is to dehumidify and cool your home. The more time that air has to sit over that cooling coil and actually extract the moisture and the heat out of it before it blows it back in, the better it is for you. Same reason you get cold in the car on that two hour trip. You know, you're nice and toasty to start with and then you're getting cold as you go on and you turn the temperature up a little bit or turn the fan down. Same way in your home. So it's not really a bad thing for it to keep running all the time. And.
