Is Your Window Unit Air Conditioner Not Blowing Cold Air

Is your window unit air conditioner not blowing cold air? There could be a problem or maybe there is not.

The main thing to think about is that the purpose of an AC unit is to keep heat out of the space that you are cooling. This means heat will be discharged from your unit, but how do you know how much is normal?

Heat is an ordinary part of cooling. The cooling process will make sure that the refrigerant is cooled off properly and that extra heat goes outdoors. When it comes to an air conditioning unit, this can be done thanks to the condenser fan and it is usually discharged straight up.

When the condenser coil is extremely hot and the fan stops working properly, the fan motor could have gone bad. You should be sure to check for power to any wires that are going to the motor. If power goes to the motor up around 110 volts, the motor may need to be replaced.

A common problem with condenser fan motors is caused by a failure of the motor bearings. This will make the fan turn hard and stop it from running correctly.

When the condenser fan motor does not have a lot of air coming out of it, you may be dealing with a coil plugged with dirt.

I wrote an article on cleaning the condenser coil to share information on how to resolve that problem. A condenser coil that is dirty will stop the efficiency of a unit right away and make the compressor work more quickly too.

The coil can also overheat on window air conditioners. If a fan fails, you will not have discharge air inside either. The same motor runs both the condenser fan and inside fan. The majority of time the problem involving overheating on a window air conditioner unit is caused by an outside coil that is dirty.

If you want to clean out the outside coil, your window air conditioner should be removed. You should also be careful so that you do not get anything wet when you clean windows. If you can take the unit from the exterior chassis, be sure to do that before you clean it. Be sure that it is completely dry before reinstalling it or turning on the power to the unit.

The most common reason that overheating occurs is that an air conditioning unit does not have enough maintenance done to it. You should be sure to keep your air conditioner cleaned for optimal performance. You should do regular cleanings to your unit each year.

In extremely dirty places, you should be sure to clean your unit even more. You should also be sure to think about heat that will be coming off of your unit as it is running. Do not think that this type of heat is a problem. When an air conditioning unit is working it will seem hot in some places, but heat discharge is a normal part of a working unit.
