Question about Heating & Cooling

Open Question

Window air conditioner keeps switching to fan mode. Which means on hot days it is blowing warm air. It sporadically switches to air conditioner mode. Room is hot because the cool air only blows for about 10 minutes. Help!

If its blowing air, but not cold, the compressor isn't engaging. There are many different possibilities on this.
Bad compressor, unit out of gas, bad run capacitor, etc, all could cause this, even a bad control panel.

Hope its something simple.

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: air conditioner symbol defrost keeps coming up so

These will defrost themselves automatically when they need to - internal sensors. If it is icing up at all in cooling, then the charge is wrong. Units such as this are very sensitive to incorrect charge, so I would recommend that you have a qualified tech come out, recover all the freon and weigh in the correct charge. If this is a "new" problem, then a leak check/locate would be in order.

SOURCE: Air conditioner blowing only warm air

possibly have a capacitor out on the compressor side of the a/c Since the unit works and its only blowing air the compressor isn't kicking in. The capacitor boosts the compressor to activate the compressor. I would have the capacitor to the compressor replaced first before going any further.

Good luck on your repair

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

My tadiran split system air conditioner is blowing warm air


if its warm air like really hot then you switched the unit to heat mode
if its blowing air in room tempereture then there is a gas leak somewhere ,so you'll have to find the leak source and after that fill the unit with freon gas.

Hi, my air conditioner works fine but if I leave it on to long it will start blowing out warm air. Then when I turn it off, it sounds like its still on. And I have to wait a whole day before it blows cool...


Sounds like the unit is icing up.

Window air conditioners are not usually of sufficient capacity to keep a room much below 74°F. If not allowed to cycle off occasionally during the day, the evaporator (cold radiator) will ice-over and prevent air from passing through it.

The way most are constructed, the water is designed to drain to the bottom near the compressor. The heat of the compressor and air provided by the condenser fan motor are intended to evaporator the condensate.

Try using a higher setting on the unit and see if that helps. It needs to be able to shut-down once in a while. If you have the option, set the fan switch to 'on' instead of 'auto'. This keeps the inside fan motor blowing all the time, with the compressor cycling as needed. The moving air will make the conditioned space more comfortable with a higher temperature setting.

Wall A/C only SPORADICALLY blowing cold air. Turn it off and back on, you can feel it's cold, but only if you're 5 inches from it. After a couple of minutes, fan is only blowing warm air again. Vacuumed...


if it blows be not with force like it used to it can be fan motor capacitor not boosting fan speed. but if speed is not the issuse. remove and clean both coils water hose

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.
