It's possible to add Freon to your air conditioner unit yourself, but you'll need some general knowledge about ACs and a few specific tools to do it correctly. The process can be dangerous, so hire a qualified professional if you feel unsure about what to do.
Can I install my own refrigerant?
It is possible to install the air handler and condenser unit on your own and bring in a professional to complete the refrigerant line setup. DIY mini splits come with the refrigerant line already charged and do not require a professional to charge them. They are the smallest, simplest systems to install.
Is it safe to recharge your own AC?
DIY A/C Charging Does Not Evacuate Old Refrigerant. The reason your car's A/C system needs to be recharged is that, over time, the refrigerant gas that makes the system work will leak out of the system. This can lead to overcharging the system, which can cause significant damage.
Is it legal to add Freon to AC?
R-22 Refrigerant Alternatives You should know there are alternative refrigerants like R-407c, R-422b, and others. So, it will absolutely not be illegal for your EPA certified technician to buy R-22 and refill your system with it. It will not be illegal to make repairs to your system just because it has R-22 in it.
Do you fill AC on the high or low side?
Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.
Which side do you add refrigerant to?
The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY'S SAKE.
What happens if you put Freon in the high side?
If you hook up to the wrong port the compressor can push refrigerant into the R134a canister under high enough pressure to cause it to burst. You always need to connect the canister to the LOW side. This way the compressor draws in the refrigerant. Refrigerant can spray out if the fitting is not connected properly.
Can you charge a car AC through the high side?
Never ever charge anything in the high side when the compressor is running.
Can I add my own refrigerant to my AC?
Simply adding a little bit of refrigerant isn't going to make your air conditioner run better for an extended period of time. It is best to have a professional come in to survey the possible damage before adding more refrigerant to the unit.
How do I put Freon in myself?

Can you refill refrigerant?
The refrigerant systems within A/C units are sealed. This means that home A/C units are designed not to need a recharge, unless a leak develops in the refrigerant system. If your unit's refrigerant system does spring a link, that leak will need to be repaired, and the refrigerant system will need to be refilled.
How do I calculate how much refrigerant I need?
No complicated math required, you simply add together the gas in the pipe, the compressor/condenser section, and the evaporator = total charge. As a result, they only capture between 30-40% of the system charge and therefore under report capacity charge.
How many ounces of refrigerant does a car need?
Most newer passenger car A/C systems do not hold much refrigerant (only 14 to 28 oz.), so you don't want to add too much if the system is low. One can of R-134a typically holds 12 oz. of refrigerant. 11.
How many pounds of refrigerant does an AC unit need?
The General Rule of Thumb When estimating the amount of refrigerant in a residential A/C unit, the general rule that is used is in the 2-4 pounds per ton of cooling. Say, for instance, recharging a 3-ton A/C with a 35-foot line set from empty level will need an approximately 6-12 pounds of refrigerants.
