I have a small window unit a/c. I bought it almost 20 years ago and other than having to hand-start the fan to get it going once, it's been fine.

Now that it's hot here, I'm running it 24/7. My question is, is it better to set it so that it remains cooling constantly or set it so that it stops cooling periodically? With this heatwave it has only stopped cooling early in the morning. It shudders when it stops cooling and starts up so that is my concern. I would think letting it run constantly would be better for it than having the cooling/compressor turn on and off. My apt stays nice despite the mid to upper 90s we are having and doesn't get too cool when things cool off at night so I'm comfortable letting it run.

What do you think?
