System was off upon arrival . Made a call for cooling on remote. Refrigerant pressures were good at first cooling start up around 121psig but only receiving a 10 degrees temperature drop across evaporator. Turned on econo cool mode and didn’t function any better. Turned system off then into heating and got a 17 degrees temperature rise. Turned system off then turned cooling back on and refrigerant pressure reading dropped drastically to 30psig. Tech support not available during after 5pm. Possibly control board communications failure to outdoor components due to the intermittent failures that randomly occur. Will contact tech support in the morning and submit diagnostics and readings to make the next step in diagnostics/repair process. Possibly need return visit pending tech support recommendations. Recommended turning off equipment and homeowner was ok with that.
