Size. It’s important to have an appropriately sized system for your home.
Shorter cycles create more wear and tear on the parts of an air conditioner, so if the system is larger than necessary, it will turn on and off too quickly.
Air conditioners that are too small for the space may stay on too long and struggle to cool your home, which can also add wear and tear on parts.

Outdoor unit exposed to severe elements, such as hail, salty air, or other airborne corrosives
