Question

I just had a new compressor installed in my heat pump. My heat pump compressor turns off (I can hear it) in air conditioner mode when the outside temperature is greater than 95F. The temperature inside the house rises quickly in the afternoons during these conditions. It works great when outside temperature is < than 95F. Is there a problem?
