I need some help with a heat pump. The high pressure switch has had a history of tripping when the outside temp is above 55. After having the unit worked on this summer it now trips at much lower temps. I just checked it and it tripped in about 1 min.. I am in west Tulsa and would like to find someone who has very good troubleshooting skills with a heat pump as I have had it looked at in the past with no solution. Thanks and you can pm me or leave contact info here.
