This pressure is formed by compressing superheated refrigerant vapor and discharging the vapor into the condenser. True "head pressure" is measured at the discharge side of the compressor, not at the liquid line service valve such as on most split systems.Over time, refrigerant can leak out of an air conditioning system, keeping it from doing its job. A Freon recharge is a very common AC repair, though if you need one, there’s probably also a leak somewhere that needs repairing. The average refrigerant refill cost is $200–$640 for a central AC unit, though fixing the leak may cost more.

So the refrigerant volume is less and when the unit is heating and needs less refrigerant, a smaller indoor coil can cause a high head pressure especially if mild out. We use a lot of ADP coils but never on heat pumps. Always use the factory specified coil for this reason. But that's high pressure trips.

Allow condenser to equal ambient temp. Then read pressure of condenser. Read pressure on PT chart. If no non condensables exist the pressure will be equal to what PT chart reads at that temp. Example: r 410a 80° f ambient refrigerant press should be 236 psig. If I read 290 psig my system has non condesables.

The "Head Height" of a pump is the maximum height it can pump water to. So if a pump has a 100ft head, then it can pump water to the top of a vertical pipe that's 100ft above the pump outlet. Now water pressure due to gravity is around 0.43psi per foot. So the head pressure of a pump with 100ft of head would be 43psi.
