4 Main Parts of the Outdoor AC Unit

Imagine living in a warm and humid area like Fort Lauderdale, FL without any way to cool your home. With the consistent hot and humid weather conditions, air conditioning units offer us a reprieve and a haven in our homes. For this reason, it is important to know as much as we can about how an air conditioning unit works. 

Now, we know what you’re thinking, “How am I supposed to know this?”. Though it isn’t necessary for you to have the expert knowledge of a certified HVAC technician from Air Pros, it is essential to know at least the main parts and the things that go wrong with them. 

Common Outdoor AC Unit Parts

Recently we wrote about the common air conditioning parts and terms on our blog, and today we will dive deeper into the main components of the outdoor or “condenser” unit. Having this knowledge will help prepare you to recognize needed repairs in your AC unit. 

Condenser Coils

The condenser coils in your AC unit are responsible for moving the hot air from the inside to the outside of the home. They do this with the help of refrigerant fluid which runs through the coils to cool off the home. 

As the air conditioner works to cool your home, these condenser coils accumulate dust, dirt, and grime. This buildup may impede their wonderful work of removing the unwanted heat. As a result, the efficiency of your AC will go down and increase your energy bills. For this reason, it is important to have a regular maintenance inspection with an AC repair tech in Fort Lauderdale, FL

Dirty coils are just one of the few things that can hurt the performance of your AC. Read about the other problems that will slow down your unit on our blog. 


Refrigerant fluid, otherwise known as Freon, is a substance that runs through the condenser coils to cool the hot temperatures in the air. When there isn’t enough of this fluid, your AC will not cool fast enough. With an excess of Freon in your AC, your condenser coils may freeze up and cause the AC to stop working. 

Clearly, this outdoor AC unit part is essential to the health of an AC unit. However, we highly discourage anyone from attempting to refill the fluids by yourself as they are highly toxic. Read more about how Freon works on our blog. 

Expansion Valve

Another important part of the outdoor AC unit is the expansion valve. The role of this valve is to relieve the pressure of the refrigerant fluid as it travels upstream to the evaporator. As the pressure decreases, the fluid cools off and moves to the evaporator. This function creates the cool air we so desperately desire on very hot days. Sometimes this valve gets clogged by contaminants and will need to be cleaned out by an AC repair tech in Fort Lauderdale, FL

Air Filter 

Air filters are an essential part of that AC unit because they catch the dirt, dust, and debris in the air that comes through the outdoor unit. Air filters are tied directly to how the quality of our air is inside the home. With time, air filters get clogged with all the debris and must be cleaned in order to promote clean air. 

Depending on how much you use your AC, air filters must be changed out every 2 to 3 months. This will ensure that your home is safe and comfortable for everyone to enjoy. It will also ensure that your AC is working at optimal levels to cool your home.
