This is an example of ambient plus 30 for those that are new to this forum. Lastly, I understand all the variables involved.

The first thing to realize is that when a system is off and equalized, the system’s pressures on both the high side and the low-pressure side will match. In the example of an R-410A packaged unit with a surrounding air temperature of 70°F, the pressure on both the high and low-pressure side of the system will be 201 PSIG.Not much more to add, really. 0 PSI on R-12 is about -21 degrees. Depending on your target temperature, you will be very close to, if not below atmospheric on the low side. If you had to put more than half the charge in it, you probably have an obstruction at the metering device.

Jan 27, 2021 · This would typically cause a low suction pressure, and a low superheat. In heat mode, a dirty air filter causes low airflow across the condenser. This can cause extremely high head pressure. In heat mode, a dirty outdoor coil can cause a low suction pressure. As an example, Trane includes a pressure curve chart with many heat pump condensing units. As a ballpark & it depends on a lot of factors, suction should be in the range of 60 to 80 & head should be in the range of 150 to 300. I've got a 2.5 ton heatpump, @ 90 degrees in heat mode the suction should be @ 74 and the head should be @ 255.
