Need help troubleshooting A/C problem on a 2014 Hyundai Santa Fe (FWD) GLS

What is your question?

Having issue with the A/C on for an extended period as the air will slowly become warmer and the air flow coming from the vents gradually decreases although the fan blower is on full blast. When I change the fan speed I can hear the blower motor change to the different levels. I can hear the a/c working and all of the controls on the dash seem to be working. The temperature controls work as does modulation of the airflow vents. I had the car inspected and no issues were found with pressure, the compressor or leaks. The only remedy I've found is to switch off the A/C for approx 10-15 mins with the fan still blowing. After which the air flow will gradually increase back up to normal speeds. I'll then switch the A/C back on again resulting in cold flowing air. This works temporarily as the symptoms will reappear after a bit forcing a repeat of cycling the A/C off and on to get things working again.

How long has your 2014 Hyundai Santa Fe had this problem?
