Chuck, I know what your saying, but my only concern is with the customer. You can't tell me that needle hasn't dropped like a rock on you before. It's done it to me. On something as much of a crapfest of a happy customer as a warranty replacement coil (which btw, we are starting are rounds again....*sigh*), why take the chance? We usually just close it off, recover, repair, pump, recharge (virgin)."Better tell the sandman to stay away, because we're gonna be workin on this one all night."
"Dude, you need more than 2 wires to a condenser to run a 2 stage heatpump."
"Just get it done son."

TXV, he added refrigerant thinking it was low most likely but the pressures never changed. Since they didn't TXV. just let them change it a TXV is a simple device that can go bad easily.

With a restricted metering device, there is little heat load picked up in the evaporator entering the condenser to be rejected. Head pressure falls due to lack of heat load. Pressure and temperature are relative; if the temperature via heat load is reduced, so will the pressure be reduced. And with that the saturated condensing temp approach to outdoor ambient temp (the basis for subcooling). Liquid stacks in the condenser, reducing the amount of coil that can actually condense superheated vapor from the compressor back to a liquid. If the vapor is able to condense at temperatures near outdoor ambient temp, there won't be much subcooling."In this house we obey the laws of thermodynamics!"
