Have you ever been inside an air-conditioned room and felt cold, hot, or just a little sweaty? Did you know that this is common in AC's? Standard air conditioners use Freon to lower the temperature of the air inside your home. This is because the refrigerant has to be heated up before it gets to the air conditioner coils. The coil also needs to have enough cool air pressure to condense into a liquid that cools down the Freon.
Something that Probably Didn't Know about ACs
Low-quality air conditioner produces this type of refrigerant, called Freon. This causes your AC to run very hard and sometimes break down. Over time, the Freon can buildup and ruin the insulating material between the coils on your air conditioner. Eventually, the motor will start to overheat and burn out.
When it comes to repairs, these types of problems can be expensive. So why would you waste money on an air conditioner when there are cheaper ways to cool your home? If you don't want to deal with the hassle of calling a professional AC repair Fort Pierce, FL, you should learn a few things about air conditioners, so you'll know exactly how they work. But first, you need to know the basics. Here are a few things you should know about air conditioners.
What is Freon?
In a standard air conditioner, Freon is heated to make the refrigerant. The refrigerant is then directed to the expansion tank, where it is stored until you're ready to use it. Freon is sprayed into the expansion tank to produce cold air. The liquid refrigerant is sucked into the tubes in the back of the air conditioner through a drain line. It then travels into the rooms where you're trying to cool off.
Since refrigerant is electrically charged, it will conduct electricity if it comes in contact with other metal coils. One of these metal coils is the coil whine, and it is the leading cause of air conditioner coil whine. You may have heard the term "coil whine" before, but you probably aren't sure what it's all about. It happens when metal coils get hot, and the electrical conductivity increases. Since heat rises, it makes the metal coils hotter than the surrounding air, which means that they conduct less electricity.
What does it do?
As the air conditioner sucks air into the expansion tank, it uses the Freon refrigerant as a coolant. When the air passes over the coil, the heat causes the waves to become hot again, which makes them produce even more heat, and so on. This can cause the air conditioner to overheat and shut down completely. The most common cause of this is that a poor design allows hot air to pass over the coil.
Other causes include low coolant level in the expansion tank, low pressure, low temperatures, and air blowing from the top of the house into the expansion tank. However, regardless of the cause, the result is that the coil whine is heard.
How to fix the coil?
The coil whine occurs only when the air conditioner is in operation, and the Freon refrigerant is flowing through the coils. When the air conditioner turns on, it starts up the refrigerant, draws it through the expansion tank, and adds it to the evaporator coil, a part of the air conditioner.
The coil whine begins when the refrigerant starts moving through the coils, making the cool air hot and causing the coil to whine. If you want to fix the coil whine, there are several things you can do. For example, many manufacturers recommend removing any Freon-based air conditioners from your home and replacing them with new units.
Also, be sure that you change your air filter regularly. This helps to keep your air conditioner free of dirt and debris that might clog the Freon vents. Also, be sure that you regularly clean your air conditioner to remove any dirt or debris buildup inside the ducts. These simple steps can make a big difference in the way that your air conditioner works.
