2019 York air conditioner. Unit has thawed. Check pressures and they are good. All electronics are within specs unit is 2 years old. Customer mentioned they had changed the filter before I came and it was very dirty. Dirty filter caused lack of airflow causing the coil to freeze and with it being as frozen as it was unit need to that before running it after changing the filter. Temp split is 18 degrees. Let customer know to change filter one a month. All okay at this time.
