Samsung window air conditioner

We've had this unit for several years without a single proble and now, suddenly, it only blows warm air. I figure it needs Freon but have no idea how to do that and can't get any appliance repair person to even take a look at it.

    The Unit is only a few years old. I haven't checked (not a plumber or an electrician) but I'm fairly sure it's the newer gas style unit, just because of its age. I appreciate all your info but I really just want to get someone to check it out. Samsung's Help Desk is useless. They sent requests to two contractors in their active files: one doesn't work on window units and the other one never even got in touch with me. Anyway, thanx again.

Freon or R13 is no longer allowed to be used in air conditioners because it attacks the ozone layer when it escapes. There are heavy fines for intentional release into the atmosphere. If an engineer was to replace the gas with a legal refrigerant then he would want to collect and flush any remaining gas for safe disposal and change the rubber seals in the pump etc. Apparently the new gas will attack the old type seals. I was going to get the aircon recharged in my Mazda RX7 but it would have cost about £300 because it had the old gas but then we had a rubbish summer so I didn't bother. It all seems like a money making excercise especially considering the huge amounts released before 'Green Fever' swept the world. There is however a 'drop in replacement gas' which is compatible with the old seals and remaining nasty gas. It usually contains a leak stopper and flourescent dye to help find where any leaks remain. Try typing DROP IN REPLACEMENT FOR R12 REFRIGERANT in a search engine or a popular internet auction site. You can then recharge your own aircon for a fraction of the price after a bit of study. Good luck.

    Ok so the rating for my solution is 'almost there'

    I am assuming that all you need is a recharge of Freon like you said.

    I'll try a little harder.

    You should be able to find two valves on the refrigerant pipework that look like car tyre valves (in fact they are the same size and are called Schraeder valves)
    If these are not like car tyre valves but more like a bayonet fitting then you have the current legitimate gas and you can ignore the following.

    Remove the dust caps and place a tyre pressure gauge on one of them as you would a car tyre. the gauge might go off scale or read 60 psi or nothing.
    You can be sure that if the reading is nothing then you have a really bad leak in the AC. This should make you think about scrapping the AC.

    If there is still a bit of pressure there then the leak is minor and a recharge may last a season or a few years. Just as important
    no moisture will have ingressed into the pipework.

    Now if you make subtle enquiries around small garages in person, you may find there are mechanics and owners that cant wait to get rid of their black market stockpile of R13 and will gladly regass your home AC for beer money.

    Eventually you will need to get a new AC or have the conversion.

    Hopefully the solution is apparent now?

04 lincoln aviator AC blows warm after charge

Hope you have fixed this by now. Look up internet articles about a diagnostic sequence for your climate control. On some of the units a sequence of button pressing will generate a exam. It could be a ductwork door is not working to allow chilled air into the cabin.

Remember several things. The pressure reading of 30 may not be Freon but contaminated air and Freon. 30 is a measure of pressure or volume but not purity. Then depending if the system is clogged, the high pressure cut off switch that is measured on the high pressure hose may be cutting out the freon flow.

My ac in my 2006 saturn ion blows cold air when its under 80 degrees outside but when its over 80 degrees it will blow warm air sometimes and cold sometimes what could be wrong with it

You likely need to charge the AC with freon. If it has been a year or three since you've had it checked, it is probably low on freon and needing to have some added.

Other than replacing air filters, what else must be done to keep air conditioners working properly. I,ve used the same air conditioner for many years, but have never had it serviced. Does it need freon?

Only a qualified service technician can tell you if the unit needs to be recharged, by testing in the input and output pressure. It would be a good idea to have it serviced professionally, since it's never been serviced. It could be money, well spent. Or it could be a Long Hot Summer without the AC.

Warm air

could be several things...if all is working/blowing and its clean inside & outside with a clean filter then more then likely it's low on gas/freon......if you continoue to run it it'll pobly ice up/freeze......also make sure you hear the compressor running as well as the fan blowing. sometimes this can be tough listen for that deep rumble/humming sound thats the compressor.

97 Olds Aurora AC blowing warm air a day after recharging system

Several- The system should hold freon for years without leaking. There are pressure switches and they cut off the compressor with an undercharge and an overcharge. You need guages to measure the charge. There are testers the A/C shops have called "sniffers" which can detect a leak. If you have no leak then you need a technician to add or remove freon to get the concentration right. Or you need guages.

Fuse or Freon?

yes, you can check for freon: you can force the compressor on using 2 jumper wires. look for the wires leading to the compressor motor. Disconnect these wires from the source (not at the compressor). Using jumper wires, connect external house power (120 VAC) directly to compressor and turn that power on. The motor should start. If the copper lines (or finned radiator) get cold, then your freon is ok. There is usually not a fuse in these units.
