Has anyone had to comply with this ??? Any problems ? I'm installing Line Voltage portions for a HVAC installation next week.

N 210.8(F) Outdoor Outlets. All outdoor outlets for dwellings, other than those covered in 210.8(A)(3), Exception to (3), that are supplied by single-phase branch circuits rated 150 volts to ground or less, 50 amperes or less, shall have ground-fault circuit-interrupter protection for personnel.

This requirement shall become effective on January 1, 2023 for mini-split-type heating/ventilating/air-conditioning (HVAC) equipment and other HVAC units employing power conversion equipment as a means to control compressor speed.

Also the Air Handler condensate pump outlet in the basement has to be GFCI protected. In the past if it was 240 volt it was not.

210.8(A) Dwelling Units. All 125-volt through 250-volt receptacles installed in the locations specified in 210.8(A)(1) through (A)⁠(11) and supplied by single-phase branch circuits rated 150 volts or less to ground shall have ground-fault circuit-interrupter protection for personnel.

Yes many issues, the newer outdoor units with inverter drives will trip the GFCI. My state has pushed back the adoption of that rule
 
In Delaware I must comply. The only way out is to have a document from the manufacturer stating that it will NOT work on a GFCI breaker and submit it to " State Electrical Board " and I will get a waiver per MDIA inspection Agency
