Ambient +30 Rule & Ambient Temp +25 Charging Methods!
In this HVAC Video, I Show What the Ambient +30 and Ambient Temp +25 are and How they were used to Check and Adjust the Refrigerant Charge Level in 10 Seer, 12 Seer, and 13 Seer R-22 Air Conditioners. Ambient Temperature +30 actually means Measuring the Outdoor Ambient Temperature and Adding 30 Degrees to find the Target High Side Saturated Temperature.
