One of the most common air conditioning repairs that is performed is adding more refrigerant to an air conditioning unit. However, if an air conditioning repair company tells you that more refrigerant is needed, you may not understand what this means or how this problem happens. Here is more information that every homeowner should know about their air conditioning unit and refrigerant.
How Is Refrigerant Used Within an Air Conditioning System?
Refrigerant is a liquid that runs through copper pipes in your air conditioning unit. These pipes make up the evaporator coils and the cooling coils. As outdoor air is sucked into your cooling system, the air first encounters the evaporator coils. The refrigerant in the evaporator coils is able to absorb the heat from the outside air and slightly cool it. That air is then pushed through the system into the cooling coil section. The cooling coils have cold refrigerant running through them, making the pipes cold. As the air runs over these cold pipes, the air turns cold. A blower fan then blows this cold air into the ductwork of your home where it travels into the rooms that need to be cooled.
When Does an Air Conditioning System Need More Refrigerant Added?
One of the most common misconceptions pertaining to air conditioning repairs involving refrigerant is that refrigerant is something that needs to routinely be added to the system or topped off. Refrigerant does not evaporate, nor does it run out as it is used. It simply cycles through the coils and is not used up. As such, refrigerant does not need to be added unless there is a leak within one of your coil systems. If an air conditioning repair company is recommending that you need more refrigerant added, they will first need to find the leak and repair it before more refrigerant is used to ensure no more leaks from the system.
What Are the Signs of a Refrigerant Leak?
If you have a refrigerant leak, your air conditioning unit will not be able to produce a lot of hot air, or any hot air, depending on how much refrigerant has leaked from the unit. As such, you may feel hot air blowing into your home, you may notice your home is not cooling down, or you may notice your air conditioning unit is running for long periods of time because it is unable to cool properly.
If your air conditioning unit is not cooling down your home or producing any cold air, it may have a refrigerant leak. An air conditioning repair company can help determine if a refrigerant leak is the cause of your problem, find the repair and fix it, and then refill your cooling system's refrigerant so that your unit can heat your home again.
