My trucks air conditioning does not get as cold as it used to.?

you need R134a

R-12 was discontinued in '93

bad for the ozone , you know

the auto parts store sells a kit that comes wth a hose and all

a very easy do-it-yourself job

the kit is about $20

connect the hose to the ac recharge port ( there are two but they are diffrent sizes so you cant put it in the wrong one) turn on the ac on high , rev up the engine to about 2000 rpm and release the freon from the new can

as it's charging up keep shaking the can to fill how much is lift in it

that's it

I'm guessing this was a steady reduction over time, and not a sudden loss. So..as you may know, Refrigerant is the lifeblood of an A/C system. Loosely, it's refrigerant which carries the heat from the passenger compartment to the outside of the vehicle, thus making the passenger compartment cooler. However, refrigerant often slowly leaks out of a hose or seal. In time, this results in a steady reduction of the cold air produced by the A/C system.

The other possibility in this scenario is that the condenser

is clogged. The condenser is the part of the A/C system

that's responsible for removing the heat which the refrigerant

absorbs from the passenger compartment. It's essentially

a mini-radiator that's mounted in front of the regular radiator.

In time, the condenser can gradually become clogged with

dirt/debris/bugs. This will result in a steady reduction of the

cold air produced.

NOTE: The main cause of this problem is likely a refrigerant

leak. A clogged condenser (if at all) would really only be a

contributing factor here. First, check the condenser for dirt/debris/bug buildup and clean if necessary with a soft brush and water. This may improve the problem. If not, you'll need to take this vehicle to a garage and ask the mechanic to "charge" the A/C system (i.e. add refrigerant). Also, ask him to locate and repair the leak. WARNING: The refrigerant R-12 (also known as "Freon") is extremely expensive. Why? Because, its production was banned beginning January 1, 1996 and therefore all that remains is the Freon produced prior to this date (i.e. it's a dwindling supply). Therefore, expect to pay a premium to have your A/C charged (often $50.00 - $150.00). Although, if you have an R-134A system, which you should have, it would likely be alot cheaper.

I have a licence for car air-conditioning in Australia. What happens if you don't use your air-conditioned for about 5 minutes a week is the seal on you air-conditioning compressor dries out and the gas will leak out past the dried seal.

I don't know what it is like in USA but R134A is now the only gas used in automotive air-conditioning and if any repairs are to be done they must be carried out by a licenced person and the gas in the system "reclaimed" and not allowed to escape to the atmosphere or risk a $10,000 fine.

The old R12 fittings and the newer R134A fittings are different

you could have a set of a/c gages hooked as much as examine the quantity of freon in the device. If the device is low you could p.c.. up a do it your self recharge kit at walmart. If the freon is long gone it has a extensive leak and is in want of restoration. If the device is stuffed with freon and not working that's a fuse or between the intense/low tension switches. could additionally examine to work out in the experience that your compressor is locked up by using grabbing and pressing against the front of the grab and turning the compressor to work out if it turns loose. sturdy success and be carefull charging the device, stick to instructions intently.

If it runs on R12 go to the auto parts store and get a conversion kit to change it to R134A. You can do it yourself then and won't cost as much as getting R12 refilled. You may have to have a pro empty the tank completely though.

You can recharge R-12 with a kit but not R-134. Do not be misled...YOU MUST HAVE a HVAC LICENSE TO BUY R-134. I'm not sure what your vehicle has for type freon. You may have to take it in for a recharge. I don't think it costs too much. I would call around and ask for a price quote.

If your mechanically inclined you can get the supplies to recharge it yourself. Cheaper than taking it somewhere. Check O'reilleys or Auto Zone. All those people are usually helpful and at least half of them know what their talking about...

ur outta freon or however u spell it just go 2 the auto store and they sell a kit and stuff
