Make sure outdoor fan is turning if it is a split unit. Could be the compressor is not running due to a bad start capacitor or possible open winding inside sealed compressor. First insure that all wiring is secure and making contact on all connections. If the outdoor fan by chance is not running it could be a bad fan motor.Also if the fan and the compressor will not run it could be a contact relay bad or dirty contacts. .....note....Capacitor or Contact relay are cheap items around $10 to $20 each but a compressor is average $350 to $600 and a Condenser fan motor can be $80 to $140 just cost alone! BEWARE OF HIGH VOLTAGE WHEN TESTING ELECTRICLE DEVICES!!!! To test the compressor there are three wires that will need unplugged on the side to it. With all wires off and the main power disconnect or breaker pulled/shut off. Take an ohm meter and touch the leads to the contacts of the compressor. There is usually a Common-Start-an Run. Measure for ohms between Common to Start----then Common to Run------then Start to Run------you should get a resistance reading between each with Start to Run being the highest number! If any are open and no resistance is measure then you have an open winding and will need a new compressor. It is not repairable and must be replaced. If you take an ohm reading from any of the three post to the housing or copper tube of the suction line or discharge line and get a reading this would mean you have a shorted winding and must replace compressor aswell. Goodluck!

SOURCE: AC unit outside blowing out cold air, vents

If you have a heat pump probably there's a wrong connectionin the thermostat, but if is not a heat pump ,the compresor is not working or the unit leaked all the refrigerant.

Posted on Aug 30, 2009

Testimonial: "thank you, we have had a problem in the past with refrigerant leaking, was supposed to be fixed"

SOURCE: My outside a/c condensing unit's fan runs, but

Start the unit and go outside to see if the insulated pipe is sweating or cold, hot air should be discharging from top of outside unit. Since the breaker is not tripping, my best guess is the compressor is not operating. You might have to replace the capacitor.

If you can hear the compressor operating, then most
likely needs refrigerant

Posted on Jun 17, 2010

Testimonial: "Thanks for providing some additional clues and methods to pin down what needs replaced. Now I need to determine whether the run capacitor or the other part, for which I can't find the name, is at fault, unless the compressor is bad."

How come my AC is on but the air coming out is not cold?


Check the refrigeration lines coming off the outside unit. One should be very cold and one relatively warm. If one is not very cold, then the compressor is not working. Usually you can hear it when it is running. The condenser fan in the outside unit should also be operating. If the compressor and fan are operating, but the refrigeration line is not cold, you probably have a refrigeration leak and have lost the coolant. You will need a service tech for the repair.

Cant keep cool


You need to check that tour filters are new. Then check that air is coming from the vents and is at least 15 degrees cooler than room temp. If no air coil is frozen, or blower motor and run cap are not working. If frozen than turn system to off and fan switch is on until you feel air through vents.
You'll need to make sure the outside unit is runing and the larger copper line is cold like a can soda. If it's cold but is freezing up, it needs to have a charge added. If its running but not cold and the fan is not running or the compressor isn't running it could have a blown capacitor. If its not running at all check. the circuit breakers and reset them. And a good idea to keep the outside unit washed with water,and that it is clear of weeds and stuff.

My airconditioner unit will not cool, compressor is running, but cold air will not come out of vents


mcdevito75 here, The compressor may be running but without the fan, no air will come out of the vents, Double check the fan operation on your A/C unit, turn the fan speed switch see if the fan is working if not, see your local A/C repair shop.

check capicitor on motor, fan motor bearings may be locking up when they get hot then when cooled the motor comes back on. Then you must replace fan motor.

I have central air and heat(the unit is about 8 yrs old)..when my heat kicks off there is still extremly cold air continually coming through the vents as if there is still a fan going,but it's not from the...


Does it look like a box with four flex ducts or pipes coming off of it? if so its a fresh air/ heat recovery ventilator, supposed to bring in fresh air, keep in mind, the outdoor unit does not bring in air, it is just a pump to the indoor unit. that unit may be running independently, or wired incorrectly

Air conditioner fan is not moving air is coming from the vents but not cold


Air conditioner probably has a failed run capacitor inside the unit. Check all circuit breakers and/or fuses first.

No air flow upstairs


Cold air is denser than hot air, so is harder to move. All vents have some mechanism to regulate flow, so close all of the downstairs vents. Check to see if your furnace fan motor has more than one speed, & set it on maximum. Keeping the fan on all the time will help as well. If all else fails, you may need a more powerful fan motor.
