Your air conditioner is one of the greatest privileges since it keeps you and your family cool in the summer heat. You can continue to live comfortably in your home all day long, even when the sun is beating down on it. However, air conditioners run into problems from time to time. Because of this, you are going to need air conditioning repair to ensure that your AC unit is running at its highest efficiency. Here are four warning signs that indicate it is time for you to call in the professionals for repairs:

1. AC Won't Turn On: Obviously, if your air conditioning is not turning on, there's a problem. The most common reason for this is because the power isn't reaching the AC unit or the thermostat is not set correctly. Before calling the professionals, you can check the thermostat to be sure that it is set to cool, is at the right temperature, and has a good battery. You can also flip the circuit breaker to see if this helps power the AC unit. If these things don't work, you will need to call in the professionals. 
2. Poor Air Flow: You will notice poor air flow if you are having to turn the AC up higher than you usually do. This is typically because of a dirty air filter, which you can easily replace on your own. A dirty air filter will clog up the air flow and prevent your home from becoming cool quickly. However, if changing the filter does not work, the professionals will need to come in and either replace a broken component or clean the interior of the AC from other debris that is blocking the air flow. 
3. Strange Noises: A strange noise when you turn on the AC unit can indicate that some screws are loose, which you can attempt to find and tighten yourself. However, if you are unable to locate a loose screw, the problem could be bigger. When the fans are bent inside of the unit or the blower is broken, it will make a strange noise. You will need to call in the professionals who will inspect and replace the fans or the blower depending on what the specific problem is. 
4. Puddle of Water: If you notice a puddle of water near the AC unit, this could indicate that one of the tubes is disconnected. This is going to prevent the air from getting cool quickly, so you will want to call in the professionals right away. They will be able to resolve this issue quickly by opening up the AC and reconnecting the tube. 

By knowing some of the warning signs that your AC needs repairs, you will know what you can do yourself right away or when you need to call in the pros (like those from Arlington Heating & Air Conditioning and other businesses).
