Why are my High and low side pressures are the same on my central air?

If the high and low side pressures on your central air conditioning system are the same, it typically indicates that the system is either low on refrigerant or has a blockage in the refrigerant lines. This condition can cause the system to not operate effectively, leading to potential compressor damage. Additionally, it could signal a malfunctioning component, such as a faulty expansion valve or a clogged filter drier. It's advisable to have a qualified HVAC technician diagnose and address the issue.
