We had a new HVAC unit installed and during the hot Georgia summers the attic will get up to 116F where the AC unit is installed. The second floor below the unit will get up to 76F. The thermostat is set for 72F. Sq.ft of the attic is about 1300-1500 It has ridge vents, soffit vents and probably 10 or so roof vents. The HVAC guys have come out numerous times to check my system and cannot find any issues with the unit. It's has 10Kmore BTU's and 10K more CFM than my old unit and it did the same thing. They feel it's the extreme temps in my attic that are causing this issue. I installed a power gable vent and it has helped little. I talked to the vent manufacturer and they feel the power vent is pulling hot air from the ridge and roof vents. What do I do?
