The dealership was going to charge me 230.00 glad I found your site all cold now!

How do you charge the A/C?

Hi budjak,

This is an environmental concern as freon gas should be handled with care and by trained personnels.

If there is insufficient freon in the system, there should be a leakage somewhere and any leaks should be diagnosed and rectified before charging the system. Failure to do so would only provide a temporary reprieve and when pressure drops again, releasing freon into the atmosphere at the same time, the system is going to fail again.

If there are no more freon in the system, it has to be vacumned before freon can be charged, otherwise you are going to damage the system components. Moisture would be inside the system and this cause damage and inefficient cooling.

Charging the freon is via the low pressure port.

----------------------------------------------------------------
i was looking at the information on rechargeing the a/c system i found the amount of freon to add, but unable to find the amount of oil to add to the system.

I have 1999 Accord and recently recharged my A/C. I bought EZ Chill (R-134a) from the local auto parts store and it already had the oil, and leak stop mixed in with it. It worked pretty good and cost about $17. Hope that helps.

Hi hvyhauler,

Adding oil to the system is very subjective.

The whole AC system has many components and each of them has a certain amount. Unless you are changing 1 component, then you need to top up with the amount required for that component.

Apart from that, even if you know the compressor has a certain capacity, but you would not know how much is needed to top up unless you take the compressor out and measure the oil in it.

I don't believe anybody can recommend you the amount of oil to add.

How to charge the air conditioner

Hi ajones240,

To charge AC gas, you would need specialized equipment's to ensure the system is not over or under charged. Pressure gauges would be required. If the system is empty, it has to be vacuumed before new gas is charged.

If the system is low on freon, there ought to be a leak somewhere and this has to be rectified, failing which the freon is going to run low in no time.

Parts store sells recharge cans which you can plug into the system to charge but it is not going to be accurate and might cause harm to the system if overcharged.

When air conditioner is on and running in my driveway I can hear the compressor run for about forty five seconds and then quit for about ten seconds. I get cool air but something must be wrong.
Could low refrigerant level be causing this problem? I have not checked the pressure yet.

Thank you,
Jim

Yes, this is how it acts when the refrigerant is low. Here is a guide to help you recharge the system:

Hi my friend, first thanks for your videos they helped me a lot. I have a question; I want to fill my air conditioning system because I changed the compressor. The receiver dryer and the expansion valve, but the kit came with the oil to put in the compressor. The instructions in the kit says that I must put a half of the oil in in the compressor and the other half trough the system. I saw a lot of videos of people putting 134a in the system and nobody put oil in there too. Some of the other guys tell me that all the oil must be poured in the compressor. I already put a half of the bottle in the compressor, should I put the other half with the refrigerant in the low pressure system? Thanks.

yes put the oil in one of the lines as you connect prior to connecting it high side is better. also turn compressor over by hand about 10-15 times to get the oil through it then evacuate system and then recharge it.

Changed compresor, vacuumed system, no apparent leaks. Tryed to put in oil charge then freon. Compresor won't kick on.

What are the pressure readings, are you using a 2 gauge manifold set?

I don't have any gauges.

you can't do this with out knowing what the system pressures are, you will have to get them read by an A/C tech.

Thank you. Ill call someone today.

A/C on 96 Accord has no freon, per mechanic, and Honda dealer suggests diagnostic - vacuum and dye, replace freon. Is this the way it goes ?

Sounds like you are doing fine, let me ask a few things;

Are you trying to repair a situation where the A/C is blowing air, just not cold air?

I forget the cutoff year for R-134 and R12 (Freon). Freon is more expensive to deal with but is much colder than a R134 system.
It will cost more to fill and the sytem must be free of leaks in either case.

I will keep an eye on this post for your reply.

One thing to consider if you intend to keep the car a while longer and want the A/C to work is that lack of Freon is also lack of lubricant.
An A/C system has a precise amount of lubricating oil and a precise amount of refrigerant. The wrong type or the wrong amount will cause failure and in some situations the A/C can become a heater with too much refrigerant.
The reason I bring up this is because the compressor is turning, (at least the clutch) at all times with the engine accessories and still is engaged when the defroster is turned on to dehumidify the air. The cutoff year for which this started to be the norm in the auto industry is around 1996 and is common today. So, you might be in a position where you will have to drop the belt to not harm the A/C compressor. This will cause other issues.
Running low on oil leads to obvious wear, then metal contamination and entire system wear and then eventually to catastrophic failure. Most new cars have too many computer issues when the A/C system is circumvented, that it is a great deal of trouble to not use the A/C if equipped.
So, if you do intend on keeping the car, and even if it takes money a Honda can get 200,000 miles if maintained, you are not really letting something go that won't give you issues and end up costing a lot more later.
Certainly get the opinion of your mechanic, as he has seen the vehicle and sounds like he is not leading you astray, and see what his input is into the situation. There may be a way to lubricate the system and get by without the full repair. Your car, I am not certain but I do believe it does, may or may not have a big problem with dropping the A/C belt as a work around.

It all seems a bit ridiculous to have to consider something like the A/C as a critical component, but un fortunately, some cars are that way.
I hope the information helps.
Let me know if I can help anymore.

My stepfather used to work on cars until he fell ill and can't do so anymore. HWe have R-12 at my house and the gauge to put it on. It has been sitting until recently i purchased a 1992 Accord for commuter purposes. I want to charge the A/C but am not sure how this is done. Ive watched my step father do it before but never on an Accord. Could someone let me know how to do this?

R12 is illegal and a banned substance. You also need to be a licensed a/c technician to handle your a/c system. I highly suggest you dispose of the R12 the proper way. It is a dangerous gas.
