Upon arrival customer stated that the unit had been running smoothly for over a week since last repairs were completed and then last Wednesday it seemed to run longer and then it wouldn’t come on even after 1 hour of control calling for heat. She left it be and when she woke up this morning it was running but blowing cooler air. We arrived I checked error codes through remote and found none active and unit running. I checked delta t and had 74 return air and 78 supply air. I have a call into diakin tech support to get information about what the unit is capable of doing during outdoor temperatures below 40. If it’s refrigerant related we will need to return and do an extensive leak check but as of today all flare joints don’t have any oil around them. Will update once I get information from diakin.
