Accidentally showed up early. Will be coming back pausing for now Performed Tune up on upstairs and downstairs systems. Downstairs air handler and condenser were checked and found all components to be functional at this time and found no issues While working on Upstairs condenser found that the compressor was not running but would try and start multiple times before eventually starting and running as should. Refrigerant levels were also showing low. The compressor is potentially not moving refrigerant as efficiently or there is a possible leak but internally the compressor is compromised as it wont start when it should.
