Doesn’t blow cold air

The air conditioner when you turn it on blows air it just doesn’t blow cold air like it is supposed to. My question is in this case would this most likely mean it just needs to be recharged?


In most cases yes. But the question would be why does it need recharged. There is a leak present in order for the Freon to leak out. So some shops may recommend charging the system. Then you can drive it around and see if it lasts for the entire summer or the afternoon.

I have found in most cases that replacing air conditioning compressor and all that is required with doing so takes care of 99% of all the leak issues. When the air conditioning compressor is replaced the system has to be flushed and all o-rings replaced. It is also required to replace the accumulator and orifice tube for the warranty to cover the compressor. Once all of that is done and recharged, you should be good to go.

The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch.

The A/C cycling switch senses evaporator core pressure to control A/C compressor operation.

An A/C compressor pressure relief valve is installed in the compressor manifold and tube assembly to protect the refrigerant system against excessively high refrigerant pressures.

An evaporator core orifice tube is installed in the condenser to evaporator line to meter the liquid refrigerant into the evaporator core.
