I have a portable air conditioner in my bedroom set to 68 degrees. On cooler days it brings the room down to 68 and the compressor shuts off and it runs in fan only mode. Once the temp in the room goes back up, the compressor comes back on and gets the room back to 68 and shuts off and goes to fan only mode again.
When it is 100 degrees out it is unable to cool to 68. The compressor runs and runs and doesn't seem to cycle on and off. It is able to keep the room at 72 which is fine. I assume this is okay as it has been working great. But I thought the compressor had to take a break and cycle on and off to let coils evaporate or something? Is this normal for a portable AC unit compressor to never cycle on hot days?
