How do you put in refrigerant for air conditioning

You need to go to the auto parts and get a can of refrigerant with a special hose. Find the pipe coming from the air conditioning compressor and fill.

If you're putting oil in your air conditioning system, you should probably get the entire system replaced. A/C needs freeon/refrigerant. Do yourself a favour and get a mechanic friend or even an actual mechanic to do this for you.

- Keep the knob on RECIR and not FRESH.
- Put the air con ON, blower on max speed.
- Open the hood, inspect the inspection window glass located on the liquid line.
- If foam like bubbles are seen, charge the refrigerant gas, till the glass window is seen clear. Never overcharge the system.
- If the problem persists, check the following:
Refrigerant volume
Refrigerant pressure
Heater control base (for Hatchback)
Heater control base (for Sedan)
Air conditioning pressure sensor
Compressor and pulley
Expansion valve -
Air conditioning amplifier
ECM
CAN communication
The following diagram may help you identify the components.

Sounds like your refrigerant is low/out. There is a product you can buy at your local wal-mart/auto store called EZ Chill Auto Air Conditioning Refrigerant. I've used this item personally in my own vehicals and it works awsome. One bottle comes with everything you need including detailed instructions and is super easy to put in. Costs anywhere from $25-35. Well worth it...hope this helps.

Hi,

When your car air conditioning is blowing hot air, this means that refrigerant cannot absorb the heat coming from your car passenger compartment.

This kind of problem often cause by a refrigerant leak or a clogged condenser.

If you have a steady reduction of cold air from your car air conditioning system, the possibility is that the refrigerant is slowly leaking out of the hose or seal.

Another reason for the gradual reduction of cold air produce by your car air conditioning system is the clogged condenser but this is only a contributing factor.

To solve the problem you are experiencing, you must first check the condenser for dirt, debris or bug that is building up outside the car condenser, this is the part that is like a mini-radiator mounted in front of your car radiator;
Try to clean this with a soft brush also, spraying with pressurized water will do. This will improve your car air conditioning problem.

However,if the problem persists,it means you have to refill your airconditioner compressor with a refrigerant(freon gas).

Good luck!!!

you may have a leak in the system, need the right test equipment

mcdevito75 here, either your son in law didn"t put in enough freon or the compressor is not working, Have your local shop check it out.

There are a couple of things things that could cause this. The first thing i would check is your refrigerant level. Low refrigerant would cause your compressor to turn off. The next thing i would check is a restriction in your A/C lines. A restriction would cause a pressure difference allowing ice to build up in side your A/C lines and not allowing your refrigerant to cycle normally, and of course once the ice melted your a/c will work again.

Low side only, this means you have to charge the unit in the thicker line of the compressor NOT the thin line as this is the HI SIDE and the refrigerant bottle could explode.
