    Only thing I can think of is a wonky defrost board. That could explain the fans not running when the compressor is. I finally got a ductless heat pump fixed that would randomly stop running and not...

    Which unit was making the noise? The first ones condenser fan wasn't turning if that's the one making the noise. Was it heating or cooling in the video?

    You need someone that can evaluate the whole system including ductwork and airflow. It would really stink to buy a whole new system and still have the same problems due to inadequate ductwork. There...

    At 13 years I would replace it. Going up a half ton won't cut your bills in half, it could even increase them or make you more uncomfortable due to higher humidity. You need to have a manual J done...

    Ummm, that's not how you check the charge on a heat pump. Have them weigh in what they took out. It should be in pounds and ounces. Removing 125psi is meaningless as that is a pressure measurement...

    3 ton could be a bit much. Is this one of the inverter driven units? If it is you may be okay with that size as they can turn down to as low as 12000btus/hr. I would still do a load calc to be sure....
