The answer to 'AC short cycling' is that it is a common issue where an air conditioning unit turns on and off rapidly, running in short cycles instead of longer, more efficient cycles. This can be caused by a variety of issues, including a dirty air filter, refrigerant leaks, problems with the thermostat, or issues with the compressor or other components.
Short cycling can lead to higher energy bills, uneven cooling, and reduced lifespan of the AC unit. It's important to identify and address the root cause to restore proper operation. Some minor issues like a dirty air filter can be addressed through DIY maintenance, but more complex problems will likely require the expertise of a professional HVAC technician.
