A/C / Heat Pumps / 8139 Views

In this HVAC video I go over checking the Refrigerant Charge of a Heat Pump that is Low on Subcooling so that means it is low on refrigerant. I go over how to work the king valves. I explain what high and low Subcooling measurements are and how to take the readings. I compare a small temp sensor vs a larger clamp temp sensor from Hilmor. I explain what temperature you should have between the return and the supply for the conditioned air.
