Central ac blowing hot air outside fan not moving but making a noise

I came home from a weekend away to a hot house. I have a digital thermostat and it read 90 inside! I turned it off when I realized that it was blowing hot air. This am I went outside to look at the unit and it is making a noise like it is running, but the fan is not moving. I really don't want to get ripped off. Could you please give me some advice or at least give me questions to ask a technician so I don't sound like a walking bank.

    We have the same problem. I turned on the central air and 2 hours of it realized it was blowing warm air. I went outside to see the fan not moving and heard a noise of something trying to run. I got the fan blades moving again but still warm air? I have someone coming out this afternoon to look at it. He said probably needs a new fan $400 part? I know nothing of A/C stuff & it is Sat & it is over 100* here in the desert. I hope I don't get the run around & that someone is honest.

    I have a digital thermometer. It reads 76 degrees. I put it on 69 degrees and its not blowing cold air or decreasing the temp inside. I got outside to my unit out there and the fan isnt moving and there is no noise. Its like the thermometer and unit inside is doing everything fine but the unit outside is doing nothign and not making any moise whatsoever. It was fine yesterday evening. This I noticed this evening. Why would my unit outside not be maiking any noise like tis doign nothing and the fan isnt moving? This system itself isnt old. Its a fairly new system.

This is nothing but an either or -or ! First, make the thermostat calls for cool, there are suppose to be 2- noise outside, the fan motor and the compressor (and if a old system,a humming noise which is the contactor coil which picks up the main 240-volts).. hurry up and take a stick or something and turn the fan blades, if it picks up speed and run, then its the capicator. If not then the fan motor is bad.! (BOTTOM LINE)!

The most common cause of this issue would be a capaciter failure. I have 3 ac units and had an AC company come out to fix a similar issue and it cost me nearly three hundred bucks! I watched the tech fix the unit and figured I could do it myself with some guidance the next time. This year when another one of my capaciters went out I found a repair kit online with pictured instructions in a guide and phone/email support and saved over two hundred bucks on the capaciter replacement this time! The site I bought the repair kit from is hvacrepairkits.com - good luck!

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.


The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

Ac unit isn't blowing


It sounds like your freezing up at the coil, which in turn, blocks airflow across coil and only a small amount of air comes out of the vents. This also explains the cold air coming from fan on the outside unit, since the system cannot absorb the heat from the inside of the house through the coil. Your air outside is usually blowing out warm to hot air because thats the heat it rejects out of your system. I would turn the thermostat to "OFF" and turn just the fan setting to "ON" instead of Auto, this thaws the system out faster. Give it time to fully thaw, make sure filters are clean, and check airflow. If airflow is back to normal, your problem is more than likely the charge of refrigerant. If you have to call a technician out, make sure the unit is not frozen at all before they get there, they would not be able to do anything with the system froze. Hope this helps and good luck!

If you are using this inside your home with central air running do you have to vent it to an outside window?


Yes, it must be vented to the outside, even if you're using central AC, too. The reason being is if you don't vent it to the outside, the hot air and humidity that normally goes thru the duct and out the window, will stay in the house and your Central AC will have to run longer and harder to overcome this rise in heat and humidity. In addition, the room that the portable AC is in, will get extremely hot & humid.

Hope this helped you. Please let me know. Thanks.

I have a digital Honeywell thermostat that has a blinking snowflake. When the thermostat is on auto mode it does not turn on. When I turn the thermostat to fan I can feel and hear the air blowing out of...


If the thermostat has a blinking snowflake then it is in time delay mode which sometime can take between 5 to 7 minutes before it will turn the AC and Fan On......Then it will go to a solid snowflake.
When you turned it to fan On it starts the Fan right away..... After the snow flake has went to solid check to see if the fan is running and then look outside to see if the Fan Blade is turning on the AC..... The fan blade comes on the same time as the compressor does. Then with the fan running hold your hand above the air stream above the AC and if you can noticeablely feel warm to hot air comeing out the Top then the compressor is running also. If the outside unit is not running I would check to make sure the Main Breakers are turned ON.... After the AC has ran for a few minutes feel the copper lines that go into the house the smaller line should feel warm to hot and the bigger lines with insulation on it should feel cool to cold and sweating with beads of moisture on it..... That is a quick test to see if the unit is working properly.....If you have a Thermentor and can Check the Temperature of the Return Air and the Supply Air .. You should have about 20 Degree F Between the Supply and Return........ 75* Return - 55* Supply would Equal 20* TD Across the Coil......
That is about all you can do to check on your own....... If the compressor is not coming on or the lines are not the temperature difference then you will need to get professional help for your Air Conditioning System..... Goood Luck Hope this Helps.........

My heat unit will not blow hot air unless we go outside and hit a button on the back bottom of the unit. Once we do that it will blow hot air for that cycle. when it is time for it to come on it is cold...


If it does not have a furnace or heating elements for heating, then it is a heat pump, which is rare for a central AC system, but makes sense of the fact that it blows warm air when you reset the pressure switch, which may indicates freon pressure charge problem if your AC system has a reverse valve and uses freon to for heating (heat Pump).

Do you get heating when outside unit runs? if you do, check freon pressure levels and top up to required pressures. The button you depress is a pressure reset switch ... that is if your AC system is a heat pump ... which, as pointed above, it is not common for central ACs.

No cold air coming from the registers.


If your compressor is running outside (low hum noise) then your probably need freon .If the compressor is not running could be a bad cap or bad compressor

Goodman CK60-1C model central AC unit blwing hot air


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.
