    Can you give me more information on you're unit as far as what type of unit it is, like a split gas/elect or a split heat-pump, a package unit on the roof or ground. If it is a split system and the noise is coming from outside can you see if the condenser fan is running and if the noise is from there? A model, serial# and name would be of help also. Thank you, and we can get to the bottom of you're problem. Shastalaker7

You should confirm if the compressor on the outdoor unit is actually running. Do not be confused by the fanmotor running. If the compressor is running there should be some temperature difference on the copper tubing. You can also put your ear close up to the compressor side of the condensing unit and you should be able to hear the compressor running. If it is running and there is no temperature diffs, then you are out of refrigerant and it needs recharging. If the compressor is not running, but the outdoor fan is, then it can be the capacitor which is bad and needs changing. Lift off the top cover of the outdoor unit and you will see the capacitor.

My air conditioner is on but not blowing cold air and buzzes

The compressor is not starting. The buzzing noise you hear is the compressor trying to start and then the thermal overload trips. When it cools it will try to start again. Could be a bad capacitor or the compressor is bad. These two units need to be tested to see which one is bad. A capacitor is inexpensive. If it's the compressor it will be cheaper to buy a new AC.

My Carrier 58dxc is making a loud noise

If your turning on heat and the unit is knocking and blowing cold air, your compressor is having problems in heat mode, could be reversing valve. A tech is needed in your situation. Getting the prob fixed right away will save you dollars..
