Central Air Problem
Hi there
My central air unit will work one day, then not another. Or it will work for a while then stop. By this i mean air is blowing out of the the vents, but not cold air. Sometimes it does work however. I have a clean filter and i have tried it on auto and on fan with the same result. I don't understand how it can work one day and not work another. ANYONE know why??? Thank You for your time Sonia |

Get someone out that can properly diagnose your air conditioning problem and enjoy. :-) |

Central Air Problem
Just a simple test.
I'm assuming this is a 'central air conditioner' and not a window unit. By not working I also assume it's not cooling. Beside the issue of adequate cooling gas, a common reason for intermittent cooling is a dirty 'A' coil in the plenum. If you have an access panel, that you can open and find the A coil 'iced' up, that means inadequate air is passing through usually due to dirt, dog hair, dust clogging the fins. A qualified service man will use compressed air and vacuum to clean it. wrote in message ups.com... Hi there My central air unit will work one day, then not another.

Thank You for your time Sonia - Hide quoted text - - Show quoted text - THANK YOU SO MUCH I WILL CHECK THAT OUT NOW. IT IS A CENTRAL AIR UNIT AND YOU ARE CORRECT THAT WHAT I MEAN IS THAT EVEN THOUGH AIR WILL COME OUT IT WILL NOT BE COOL AIR. MY QUESTION IS WHERE DO I FIND THIS ACCESS PANEL. IS IT IN THE OUTSIDE UNIT OR THE INSIDE ONE IN THE GARAGE?? THANK YOU SOO SOO MUCH FOR YOUR HELP. |

We never did figure out what was wrong with him. Call an AC company. You may be able to fix what's there and not have to replace the entire thing if you keep running it and fry it. It's obvious something's wrong with it. Don't run it into the ground. Stop now and have it diagnosed and fixed. Steve |

Thank You for your time Sonia Here's the latest on my problem. It stopped working and checked the indoor and outdoor control panels and nothing was frozen. It doesn't look dirty so would the dirt be internal? Do you think it needs more freon? The outside fan does run and air comes in but just not cold air all the time. |

Do you think it needs more freon? The outside fan does run and air comes in but just not cold air all the time. Please don't take this the wrong way, but you're so clueless about how your A/C works that you really should call a professional in. Trying to do it yourself, you're just going to break it worse than it already is. If it needs freon, it has a leak, and any freon you add (provided you manage to add the freon without blowing yourself to kingdom come) will just leak out. A professional has a special dye and tools to detect and fix the leak. The whole discussion is moot, though. All you keep saying is "IT DON'T WORK." There is no way to diagnose the problem without more information, and even then, there still may be no way to completely figure out what is going on without physically being there. A little lesson on A/C: Air doesn't "come in." You are not getting cold outside air when you turn on the A/C. The outside unit compresses the freon and cools it. The compressed freon flows to a radiator inside your ductwork in the house, where it is allowed to expand. When it expands, it gets really cold. Your furnace blower sucks air out of your house, blows it through this radiator where it gets cold, then blows it back into your house. The cold air you feel is inside air that has been cooled. This radiator in the ductwork (called the condensor IIRC) is the part that may be full of crud and/or frozen. Usually it is located near the furnace because that is where the fan is. |

Low Freon will too. It is not easily diagnosed no knowing more information. My advice is to call a service technician. Even a simple job like cleaning the fins can damage the unit if done carelessly as they bend very easily. |

You're right about one thing, she needs to call for service. However, your description of "How an Air Conditioning System Works" needs some work! Example, the compressor compresses the low pressure gas to a high pressure gas where it can reject the heat (that it gained from the inside) to the outside as it condenses the high pressure gas to a liquid. The indoor blower moves air across the evaporator where it can absorb the heat from the air, which is then carried to the outdoor unit to be rejected. This process takes place when the high pressure liquid hits the indoor metering device and flashed to vapor. The change of state causes the indoor coil to get cold where it can absorb heat from the passing indoor air. Condenser is outside Evaporator is inside (for air conditioning) |

The gas becomes hot as you compress it, but cools off almost to the outside temperature, because it is outside. You should've took your own advice. "You're right in about all of this, but you shoudl have stopped...." The compressor compresses the low pressure gas to a high pressure gas. This allows it to reject the heat in which it absorbed. As the heat is rejected the gas is cooled which causes it to condense to a liquid. |

As the heat is rejected the gas is cooled which causes it to condense to a liquid. I'm not sure what I said that differs from this. I just didn't go into as much detail. And when I rereed, in this part I'm not specifically speaking about an AC condenser anyhow, just about gases and liquids. Applying it to air conditioning was left as an exercise to the reader. |
