our ac is not cooling?

Answer 1

Call the repairman, not us!

Answer 2

1. Change the air intake filter. Blocked filter will prevent air flow and can cause the evaporator coil to ice up preventing air flow even more.
2. If filter is that blocked you may need to leave the ac off like over night to allow the ice on the evaporator coil to melt.
3. If the filter is clean and you've given it a chance to let ice melt if that could have occured, it could be that your outside condenser coil is dirty and needs to be cleaned badly.
4. If none of the above then it can be possible that you may have a freon leak. This could get expensive or could be reasonable if the unit just needs a simple charge and the leak was very small over a period of years.
5. Compressor not coming on. By the outside unit there are two parts that you should hear come on. The fan for the condenser coil and the compressor that works with the freon gas moving it and compressing it from the evaporator side to the condensing side. If you only hear the fan coming on and no compressor it could be a seperate fuse or breaker switch just blew on a high load or the compressor could be completely dead... (most expensive thing to replace.)

Best of luck

Answer 3

First check to make sure that your Breaker to the compressor is not tripped or off and don't forget that you also have a disconnect (electrical) out beside the compressor, which is located outside the house. The fan unit is usually in the attic of most new homes so make sure that there are not breakers tripped that might supply power to the fan unit. Check to make sure that the thermostat is working, that when you put it on cool and reduce the temp (thermostat) that the unit tries to come on. If the compressor is running (outside) and your fan is blowing air out of your vents then consider that you might have a coolant leak in your system. Could be freon could be another coolant. Filters keep the units from working harder and also will keep the dust and particulates down but you still should have cold air coming from the vents. Once you have made all the visual checks of the breaker box and verified the compressor comes on and the fan blows air out of the vents when you call for the air to come on, at the thermostat, then call a repair person to come check out your coolant level and the units operation.

The fan works off 110Volts AC (one breaker) and the Compressor or Compressors work off 220-240 Volts AC (two breakers usually ganged together in the box). These voltages can kill so be very careful how you check. The compressors you should hear come on, outside the house, and they also have a fan inside them that should come on and blow air.

Last grab your water hose and make sure to hose off the grids in the compressors very well. That sometimes helps the air unit to cool better. Check out the link under the source list and that will help you understand how your system works.

Answer 4

In your home??? If it's in your window, you may need to clean the filter. You should do that once every 2 weeks to keep it clear. If it's really old, it may need to be replaced.
If your A/C doesn't work in your car, then it probally needs to be recharged. If that doesn't help, then it most likely has a leak. The dealership will put a dye in it too see where it's coming from..
I hope you get whatever A/C that is not working fixed before it gets too hot and muggy!

Answer 5

It is not wise to try to repair an A/C unit by yourself. There are high pressure lines that can release environmentally harmful chemicals if you disconnect them. If you are talking about a car A/C unit, you can add coolant to the system. There are several types of coolant such as Freon. If you can not tell what kind you need, take it to the shop and let them do it.

Answer 6

You will not want to hear this. We just spent 900.00 dollars getting ours repaired. The fan was running but no cool air. You may be lucky and just need freon and I hope that is the case. The big coil in our a.c. was leaking and we had to have a new one installed. Good luck

Answer 7

(1) Your air conditioner could have leaked out all of the freon.

(2) You need to clean the filter.

(3) Your inside connections have become loosened.

or

(4) Perhaps your air conditioner has run it's course of life.

Have a lovely rest of the day.

Answer 8

If you're here in Texas, that's NOT good! Could be just low on freon, but you'd still have to call a repairman. They cost $$ but it's definitely worth it.
I don't know HOW people 100 years ago survived without A/C!

Answer 9

The freon might be out..look to see if your air condition cord outside is froze over.. sounds like you will need to call the repair man though

Answer 10

I answered your question before but didn*t understand it.
I thought you were talking about an attic fan, not your air conditioner. Try putting in a new fuse . Sometimes they blow, and the fan on the furnace runs, but not the air condionter unit .

Answer 11

clean filter on furnace/then clean out side unit with water hose.if this doesnt help then you are low on freon and will need a repairman.
