Recharging should be on low-pressure side only
The low pressure air conditioner port can be found on the top of the air conditioner compressor. The low pressure port should be labeled as such.
maybe overcharged, or return air leaks (the hotter the return air the more the low side pressure)
The pressure for an R410a air conditioner system should be 118psi LP and 412psi HP. This is the same pressure as an R22 air conditioner.
it is the low pressure side
Yes
70-85/ 350/290
The high side will not hook up to the hose
relieve the pressure off the high pressure side
The Pontiac 6000 low side air-conditioner import can be found on top of the air conditioning compressor. The low side air-conditioner port will be labeled as the low pressure port.
no
The refrigerant pressure for a residential air conditioner is around 75 psi for low side input and 260 psi for high side output. If the unit is turned off the pressure will be about equal to the ambient temperature.
