At your thermostat ,
Set switch to heat, turn up temp switch.
Fan should be set to auto. Wait up to 5 mins to be surethat somthing is wrong. If your fan comes on without heat. Check gas valve or if heat pump check main a/c breaker. If elect heat or any of above dosn't work.
Call a service company. If your in Pensacola. Look up Absolute Heating and Air Conditioning.

SOURCE: air conditioner doesn't blow cold air. Continues

If the a/c fails to continue to blow cold there could be a few problems you can look for. First once you activate the system check to see if the compressor kicks in. You will hear the compressor humming . Once the a/c quits cooling go and see if the compressor is still running. If its not running its probibly gone into thermal overload (compressor overheated). If that is the case then you need to check to see if the coils are icing up if they are icing up then the problem is with 1) air flow restriction filter dirty, coils dirty simple repairs there replace filter, clean evaporator coil with a coil cleaner that can be purchased at a home repair store cleaning the condensor coil the same. 2) system is low on freon in which case the system will need to be recharged. Also, If you have a digital thermostat replace the batteries that may also be of some help. Good Luck on repairs

SOURCE: ac BLOWING HOT AIR INSTEAD OF COLD

Check to see if your outside unit is running. If not, check the breaker. If it is running you may have an issue with the reversing valve. It looks like three lines coming out of the top and one on the bottom. Trace the wires back to see that they are tight and secure. Of course, TURN OFF THE POWER first. good luck.

SOURCE: Bryant Legacy Line air conditioning not blowing cool air..

Your outdoor condenser is in heat mode. Check the wires on the thermostat. Sounds like a small wiring problem and nothing else. Good luck. Please keep me posted as to you progress.

SOURCE: AC Fan doesn't blow cold air, frozen coil noticed outside, resetting power resolves temporarily

You need to call a reputable service technician.  The freezing up usually is associated with a low refrigerant charge or low air flow.  Check your return air filter and replace as needed.

Honeywell TH6320WF when i turn system to heat and fan on auto it says heat on but never clicks on but then when i change fan to on the system clicks on but it seems to be blowing cool air


It sounds like the heat setting is not high enough. The heat setting needs to be higher than the indoor temperature or the fan will just blow non-heated air.

Amana ptac during heat mode will blow hot air , then blow cold , but will cycle back to heat eventually is this Normal?


if the fan switch is in the Run position and not the auto position you are getting cool are when the heat element is not on. this is kind of like a way to circulate the air. look for an auto setting it then should only come on when needed. Keep in mind it is normal for the fan to start blowing before the heating element is warmed up, this prevents it from over heating, or coming on when the fan is not working

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!

Hp a6320in processor fan air flow direction?


Processor fans are setup to nearly always blow air inward onto the heat sink that sits on top of the processor. The heat sink pulls heat off of the processor and the processor fan blows air onto the heat sink to cool the heat sink so that it can pull more heat off the processor. However, read the following link to see that it probably doesn't matter that much which way you put it: http://www.overclock.net/faqs/14695-opinion-****-vs-blow-way-do.html

I would definitely set it up with the processor fan blowing inward onto the CPU. If you're experiencing overheating you can try switching it to see if that helps. Use a program such as SpeedFan to monitor your computer's temperatures.

Good luck, please post back to this solution if you have any difficulties, and thanks for using FixYa.

My Home Ac Unit Is Not Blowing Any Air


This sounds like the fan not turning during cool. You will have to check the fan relay for power during the cool cycle. The fan relay is run by the low voltage side, but still there is hi voltage present. When in heat the power goes thru the relay on one set of points then in cool goes thru the opposite side. You should have a digram present, and then on the main circuit board there is a code light. Check the light for blinking or (flash) read the bottom of the board for the code ( very small print)

Heat won't come on in auto mode; blows cool air in on mde(fan)


these units has 4-steps in heating mode... step-1 when the thermostat calls for heat, the small vent fan comes on and proves that its blowing thru the suction tube and closes a switch,,, step-2 -the next click from the gas valve, the pilot lights.......the #3 step and the next click from the gas valve the main gas comes on and heat up the box. step-#4 the box heats ups and turns on the fan switch and blows heat through out the home, now wheres the steps stops, thats where your problem is located>T Y V MUCH!

Goodman PGJ030075-1 Motor Not Spinning - No Cool Air Blowing


I assume you are talking about the evaporator fan motor. Check the capacitor. Replace if necessary. If cap shows good then it's most likely the indoor fan motor.
