Why is My Air Conditioner Blowing Warm Air?

The purpose of your air conditioner, of course, is to cool your home or business. When your air conditioner suddenly starts blowing hot or warm air, there is obviously a problem that needs addressing. Solving the mystery behind the air conditioner’s antics is usually easy; one of a few problems is typically the cause.
The first diagnosis might seem obvious, but is worth checking... maybe the heat accidentally got turned on. When you set the thermostat, you might have accidentally moved the selector to “heat” instead of “cool”. When this happens, you will feel hot air coming out of the system. Simply move it back to “cool” and chill out. If that doesn’t work, you might have a faulty thermostat. If that is the case, you should have a professional come check it out.
The next thing to check would be your compressor or condenser. You'll want to make sure to check the outside unit where your compressor and condenser are located. Make sure the switch is on that sends power to the compressor. With no power, the system might stay running from the air handler inside, but it won’t cool. Also, check to see that leaves and other items are not blocking the major intakes to your air conditioning system. This could stop the flow of air and prevent the system from cooling properly.
A more common problem might be your refrigerant. Compressor problems and leaks can cause you to have refrigerant level problems that could stop your air conditioner from putting out cold air. This type of problem is better off being handled by a professional. Low refrigerant charges can lead to low or no cool air output and potential icing on the condenser coils on the unit outside. The repair can be relatively inexpensive, unless it's not properly handled. If you end up with a faulty compressor, you might need to replace it. This, on the other hand, can be a lot more expensive.
Lastly, of course not least, the problem could also be a clogged air filter. Even though this usually doesn’t keep the air conditioner from at least putting out semi-cool air, having a dirty air filter can make the system run inefficiently and prevent proper cooling. For a few bucks, you can get a new filter and put it in yourself. When you neglect doing so, you can have dust and dirt quickly clog up the filter and reduce the ability of the air conditioner to cool.
The best way to be sure your air conditioner is running properly is to contact The Cooling Company and have an experienced, qualified technician come check out your system. You can reach The Cooling Company at www.Thecoolingco.com.
