My unit blows cool for a few minutes and then blows hot. How can I fix it?

Is there a way to open the unit myself and try to fix it?

    There are screws on the back of the unit. Do these units have a liquid coolant that would need to be replenished, like freon; or might it just need a good cleaning? Thank you for your help.

    As a repairman of thirty some years, I expect there is a way to open an air conditioner and try to fix it. I always start by taking out some screws. Can you see screws that would open some covers?

The liquid coolant is not supposed to be replenished. It is supposed to be sealed inside metal at all times and temperatures.

If it has escaped, you will need a brazing torch, a set of pressure gauges, a container of new freon, a license to buy the freon, a vacuum pump, some fittings to attach the gauges to the pipes, the ability to measure the quantity of freon accurately, and some education so you can avoid hurting yourself with molten metal, liquids at 40 degrees below zero, and pressures in hundreds of pounds per square inch. The tools cost nearly a thousand dollars. The license and education, I don't know the price. At least several hundred more.

Unfortunately, a short burst of cooling followed by poor performance is usually caused by the freon having partially leaked out.

The best you can hope for is an electrical problem. Those are cheaper and easier to repair, if you have voltage and amperage meters and know how to use them.

Good luck!

Frigidaire AC window unit, model fam185r2a (18,500 BTU) only cools for a few minutes before it cycles off and just fan blows. Then a few min later cool air cycles back on. Is this a thermostat issue?


The window units normally have a sensor thats attached to the front of the indoor coil. This controls the thermostat. I usually pull this sensor away from the coil because it stops cooling before the room is cool. It is attached to the cold coil so it senses the coil temp, not the room temp. You can normally see it when you remove the air filter. Don't break it! It may be a wire or small copper tube

Monte carlo blows cold air and overheats


It really runs hot within a minute of starting ?
An engine that runs hot in a few minutes is often having problems with the water pump or a blockage in the cooling system. The thermostat does not open until 195 degrees which takes 5 or 10 miles of driving.
During that time, the water pump should be circulating coolant in the block and the heater hoses.
A leaking head gasket should be putting extra pressure into the cooling system, and-or dumping coolant into the cylinders which would come out the exhaust pipe. But it should still take a few minutes for the engine to reach the boiling point of 240 degrees.

Window air conditioner cools (very icy cool air) for a minute or two then switches to fan. Will then stay on fan for about 10 minutes and then once again get "very cold", but only for a minute or two


Before I even read that far into your post, I was thinking "thermostat" replace it...It seems to be failing badly. If you take it into logical perspective...normally the unit gets turned on, then takes a bit to get cold, then once it reaches its pre-determined temperature, turns the unit either "off" or just blows the fan...by kicking off the compressor. This unit you have is getting this cycle done within 5 minutes instead of a few hours...replace the thermo and you should be fine. Now if you could post the exact model number here I can go look up the part for you.

Compressor will cut on run a few minutes and shut off hot air


The compressor is probably going out on overload. There may be a small refrigerant leak thus making the compressor run hotter than usual. If there is not enough refrigerant in the system, the compressor will not get the refrigerant back to it to keep it cool. This is a safety feature built into the compressor to keep it from overheating and locking up. You may want to take it to your local appliance store and have it looked at. Most of the time it usually is cheaper to buy a new unit than to pay for just the labor to have them fixed.

Unit cools for a few minutes then stops cooling. Even fan stops blowing air but the unit remains 'on'


unit may be short of gas. will run for a few mins before low pressure switch turns the compressor off. you will need to get an engineer to check gas pressure

Hot air blows but cools down in 15-20 seconds.


You likely have a restriction in the heater coolant hose circuit - perhaps a coolant control valve not fully opening, or a kinked hose.
Insufficient coolant volume is flowing to keep the heater core hot.
Try back flushing the heater core system with a garden hose to check flow.

AC cools then blows hot air, tempature needle goes up & down


Sounds like the thermostat is trying to stick,and is causing the engine to over heat,therefore condenser is not cooling the freon down enough to cool.Have the thermostat changed and the cooling system bled out,this is most likely the cause.

You need to have an AC tech come out and do some preliminary testing on this.

Wont no water to empty or drain


Either the unit is really dirty or it is low on refrigerant. A unit tha is low on refrigerant will start off cold and withing a few minutes, start warming up. If you aren't seeing any water its because of one or both causes listed.
