Depends on the size of the unit and when it was built. Modern A/C units contain no Freon (R12). It was banned in 1996. Call a home A/C professional.
If your air conditioner blows air but it's not cold air then you probably need freon in your air conditioner
you need 8.00 oz. of oil and 2.25 lbs of freon
1lb 6oz is all u need
Actually no technical skills needed to check the Freon level. Home central air conditioners have a Freon scale on it. One just need to read the scale and determine whether the level of Freon is sufficient.
Varies by vehicle usually 1-3 lbs.
If you are talking about removing the freon in the a/c system then you will need a freon reclaimer.............
Never. A properly operating AC unit will have no leaks, thus never need recharging.
You will need a Freon recharge kit. Connect the hoses of the recharge kit to the ports on top of the air conditioner compressor. Release the Freon into the compressor.
you would need to add freon
The answer should seem obvious... you have a leak. It could be anywhere in the system, which is unfortunate for you. You'll probably need a tech to come and do a leak test on your system.
If your central air conditioner isn't cooling your house anymore, you might need to have more freon or coolant added. You will need to call a professional.
An Air Conditioner needs the Type of "Refrigerant" that is stated on the (Identi-Plate) usually located near the condenser.
