Common Difference between Condenser Coil and Evaporator Coil

Difference between Condenser Coil and Evaporator CoilWhen dealing with air conditioning systems, things can seem complicated, especially when trying to install something like a Trane condenser coil replacement. As a result, it’s easy to get some things mixed up. For example, many people struggle with the differences between a condenser coil and an evaporator coil. While both are crucial to air conditioning, they’re both very different. Here’s a little explanation.

Background on Air Conditioners

Before getting into specific coils and their functions, it’s important to first understand how the overall system works and what goes into it. The key to changing the temperature of the air going into the system is the phase change in the refrigerant. When a liquid refrigerant is changed into a gas, it absorbs heat. Conversely, when the refrigerant returns to a liquid, it releases heat.

Hot and Cold

In order to achieve this process, the system must do two main things: change the liquid refrigerant into a gas and turn the gas refrigerant back into a liquid. This is where the coils come in. The evaporator coil assists in “evaporating” the refrigerant or turning it into a gas. As a result, heat is being absorbed, lowering the temperature and producing cold air. The condenser coil, on the other hand, “condenses” the gas refrigerant back into a liquid. The heat released in this process raises the temperature producing hot air.


Because the two coils produce air currents of different temperature, this impacts their location. The evaporator coil, for example, produces cold air and is therefore located in the indoor unit, while the condenser coil pumps its warm air outside in the outdoor unit.

At the end of the day, you want your air conditioning system to function properly in order to heat or cool your facility and keep things running smoothly. A part of that process is knowing the difference between a condenser coil and evaporator coil. Whether it’s for getting a new system or just a Trane evaporator coil replacement, it’s important to know the differences between these parts.
