on the other hand, Why is my air compressor short cycling?
Pressure or temperature control differential is too small: When the pressure controller’s low pressure differential is set too tight, it can cause the compressor to short cycle. When your temperature and pressure differential is too small you’ll take longer to achieve set point and use more energy use in the process.
also, What is considered short cycling? What is Short Cycling? … Short cycling is an HVAC term used to define a situation where a furnace or air conditioner turns on and off too frequently. The term “short-cycle” describes the period of time that your HVAC equipment is actually running, and the shorter this cycle, the harder your system needs to work.

What causes AC compressor to cycle on and off?
Short cycling, when the compressor constantly shuts on and off, is one of the most common air conditioning problems.
