Does a new ac system need to be charged?

jinxed

Hello, I bought a new rheem ac system 1 wk ago and I'm using it for the first time and it's not cooling, my ? is does the system come charged from the factory or does the installer have to charge it? Thanks in advance.

It should be fully charged.

Charge should come in the condensor.Installer has to evacuate the line set and evap coil before opening the valves to let the charge fill in the vacuum.It then needs to be checked to make sure it is not undercharged or overcharged.

Most home air conditioning system components are pre-charged at the factory -- the condenser, evaporator coils and insulated refrigerant lines. Metal membranes seal the openings and the act of screwing the lines onto the condenser or evaporator pierces the membranes and allows refrigerant to flow. However, if one doesn't mate the parts properly, it is possible to have the refrigerant leak away, requiring a recharge. Installers typically check the pressures with an HVAC manifold gauge set right after the system is assembled and add refrigerant as needed. They also perform leak tests to make sure all the joints are tight.

Depends on what you bought. A new 410A AC will come with charge,a dry shipped R22 AC would not.

Is this a package unit or a split system?

We had a new system (2 years ago) and the cooling was not very effective. We had the HVAC installer out and they told me this particular unit comes precharged with a enough refrigerant for a 10' run, but ours was 20'. He charged it up and it worked perfect
