Air Conditioner Blowing Air But House Not Getting Cold

My air conditioner is blowing air but its not cooling the house, what gives?

Here is the situation. Your a/c unit is running non-stop, you can hear it but for some reason the house is not getting colder. What is the matter? Here are some possible reasons and solutions to your problems.

1. The a/c filter is clogged. Check it and if its dirty replace it with a new one. These filters are really cheap and if this is the problem you are in luck because this is by far most simple fix you can perform.





2. Your evaporator coils are clogged. If this is the case there is not a good air flow around the condenser unit. See if you can clean them by yourself but depending on the unit you might have to call a service repairman to do it.





3. Check the fins on the fan located in the outside unit. Are they in good shape? Have they been compromised at all? If the fins have been damaged then you can try to straighten them out as best you can but you may have to replace them.





4. Low refrigerant. If your central air conditioner is out of or low on refrigerant then its CF pressure will be low and it won't condense and re-condense in your compressor the right way. You will need, at this point, a professional to come out and first, check for leaks, and then fully recharge your refrigerant levels.





5. The compressor motor. It might be burnt out. You know this is the case because it will not make a smooth sound like it should but a very deep and loud noise. Check the fuse first. It may be burnt out and if that's the case the fix is cheap. But if your a/c motor has indeed worn itself out it will be costly to fix it.

Before you do any of this check the thermostat first. Make sure the temperature is more than fifteen degrees colder than it is outside. If the weather is 90 degrees outside then your thermostat needs to be at 75 on the inside to adequately cool your home.
