A 2007 Lexus doesn't use Freon, it uses R134a. If the system is low on R134a, then you really need to find the source of the leak and fix it. A/C coolant is not something you just have to add more of from time to time, it is a sealed system and should never need any added. If it's low, there's a leak, and if all you do is add more it will all just leak out again after a couple months.

If you've never worked on an air conditioning system before, I would recommend you take it to a shop and get it checked out.
If the system is low on freon, you have a leak that would need to be fixed to keep any freon you add from leaking back out. And it could have an electrical problem instead of being low on freon.
Freon gas is minus 35 degrees when it comes out of the can.

You have a leak somewhere in the ac system. I'd add some freon for now, but you need to get the leak fixed eventually. Just go get a can of freon and follow the directions. It's really easy

It is the same as with any other car. The freon must be added through the low side service port. If the freon is low, it means that there is a leak. It is recommended that you find and fix the leak before charging the system with more freon that will just leak back out.

Refrigerators don't need freon added to them unless there is a leak and until you find and repair the leak you have not fixed the problem.

A lot of people think when their refrigerator is not cooling that they need to add freon. This is not normally the case 99% of the time. You are a lot more likely to have a defrost problem or a fan problem if your refrigerator is not cooling.

If you actually do need freon, call a reputable professional. There are a lot of guys out there that will just add freon because you told them it needed it, charge the heck out of you and then leave. Be careful about telling some jack leg that you need freon.

first check your fuses and any relays sometimes you have multible relays that are the same in a fuse box that you can switch around but i would bet you have a leak either in your compressor or in your line if the clutch is not kicking on and off or running all the time when you turn it on thats because your freon has leaked out the system is sealed freon does not go bad if there is no pressure in the system it will just blow warm air your question is vague so if your blower is not blowing bad blower motor or a fuse if warm not getting cold your system has a leak if you have not broke the system you can try stop leak 2 cans to seal a leaky compressor compressor could be bad if it wont spin noisy clutch could be bad need new compressor but if a leak after stop leak add the right amount or r-134a 2 to 3 cans if the compressor kicks on on the first can of stop leak or freon your system did leak down and you hope the stop leak fixes it but first check all your lines are tight and that the freon is not leaking from the high or low pressure ports the valve can leak sometimes make sure your caps are on take some spit after you add freon back into your system see if your spit blows a bubble if it does replace or tighten the valve. a few things to check start with power fuses then add a can of freon if you have power now clutch engagement if you add and kicks on there is the reason a leaky system it will all leak back out in a day or several days... thats why you can add the stop leak things you can try or take it to the shop and pay someone some $$$$$

The Air-conditioning needs to be re-gassed. Take the car to an Auto Mechanic to get the Air-Conditioning re-gassed. They might also need to check it for leaks to make sure the gas stays in.
