If it's not blowing cold air it could be for these reason...

1... it has a low charge. generally if the high pressure switch in the unit detects a low charge it will shut the compressor down to prevent it from seizing up.

2 you have a leak...once again the sensor in the system will shut down.

3 debrie across the condensor... you have to have airflow over the coils and fins of the condensor to disapate the heat thus providing the cool air that the fan blows.

4 the thermostic sensor is bad. this is responsible for the adjustment of how and when the compressor runs.

Unfortunately because a/c units for residentual and commercial use a freon based refrigerant you have to be liscense to repair the units. so my suggestion is to contact a certified HVAC technician to work on your unit

please rate this........thanks

Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.

Hello, It sounds to me like your low on freon/refrigerant. You'll need to have someone test the pressures for you.

The capacitor is located inside the control panel on the outside unit. It is round or oval and silver in color.It runs the outdoor fan and the compressor both.
The terminals are marked= C, /F or fan/, H or herm. C-F-H.
The microfarad rating is printed on the capacitor. Make a color code wire diagram before removeing wires.
Disconnect power to the unit. Use a insulated screwdriver to short out the terminals on the capacitor before removing it.

SOURCE: uotside unit blowing cool air but hot on the inside

It sounds like you have a unit called a heat pump. When a heat pump unit is in cooling mode the outside unit blows hot air and the inside unit blows cold air. If the outside unit is blowing cold then the indoor unit is most likely blowing room temperature or warm air. It sounds like the thermostat could be controlling incorrectly or you could have a failed reversing valve which is the device that switches the unit from heating to cooling mode.

2 things could be happening. 1, inside unit needs filter changed and coil cleaned. 2, unit is low on freon. A/C tech should be able to check for both. You can check the a/c coil to clean it yourself but to check for low freon this will have to be done by a a/c tech due to the complexity of the system. the ice is caused by a series of things however, check the a/c filter and the coil located behind the filter. this coil should be free of any debris. if you have indoor pets sometimes the hair clogs the coil causing the freeze up.. To clean the coil you need to get a small weed killing sprayer.. At the a/c supply house you can purchase cleaning solution that is easy to use an safe for the enviroment also leaves your house smelling great. if the coil inside has been cleaned check to see if the coil outside is clean if not you can clean it with a water hose by spraying the coils out. MAKE SURE TO KILL THE POWER beforehand. Also spry the water onto the coils only and spray in the oppisite direction of air flow. Have system checked by a/c tech if you do not feel comfortable doing any of these suggestions

Check the t-stat to make sure that the "fan" switch is st to auto. If not the fan is in the "on" position and is always on. Otherwise, It sounds like your "Central Air" is a packaged unit(Furnace and air all one unit outside the home) and the fan relay inside the unit is stuck. This need to be replaced. It is the rectangular unit with the leads from the fan motor attached to it.

Central air conditioning system is blowing warm air.

many, many. Is the outside unit running? If it is, is the compressor running? Feel the refrigerant lines leaving the unit. Little one should be warm. Big one should be cold, probably sweating.

There may be a leak. You might try shutting it down and taking a look inside. On the other end, there may be something wrong with your components inside. The compressor outside is to provide coolant. Inside, the fans actually cool the air. Make sure all doors are on the blower downstairs, and if all else fails, call a technician. Good luck!
