    That's a 134a system, so at 90F your low side should be 45 to 55psig and the high side should be 250 to 270psig. Having LP side high, and HP side low points to the system needing service, likely a bad compressor. Don't attempt to add refrigerant with your LP side more than double the normal value. You could blow up a can of refrigerant. Some charts to help - https://www.google.com/search?q=auto...kWy7lWHSnhI%3D
