What’s the Most Suitable Place to Install a Condensing Unit?

The refrigeration cycle requires many systems to work properly since it is segregated into multiple phases. For example, there needs to be a heat sink where the excess heat can be dumped to maintain the temperature inside. Similarly, a heat pump should maintain the energy flow from one end of the system to another.

However, the condensing unit is the most important part of any refrigeration system. Responsible for handling all the refrigerating functions, it comprises a cooling system, refrigerant flow pipes, compressor, heat sink, and many more. These parts vary from one unit to another according to the output required.

Why choosing the ideal place for the condensing unit is essential?

The first thing to note is that the condensing unit cannot be placed anywhere, according to your convenience. You need to fix a proper position for the installation to get maximum output and yield. If not, there might be huge consequences for the future. Below are some examples to help you gain clarity.

  • Improper placement of the condensing system can lower the output, causing irregular refrigeration in the entire unit.

  • The refrigerant fluid pressure will have a huge imbalance, so the entire system won’t be able to lower the temperature faster.

  • Also, if you place the condensing unit improperly, the entire refrigeration system will consume much energy. It won’t align with the energy star rating, leading to compliance irregularity.

How to decide the right place for condensing unit installation?

Below are some of the considerations to make while installing the condensing unit.

  • Ventilation: One of the primary needs of the condensing unit is proper ventilation. Heat dissipation or exchange with the outer environment will become quite difficult without it. So, always install the unit in an open space with enough fresh air flow. Closed spaces or confined areas must be avoided if you don’t want its working to falter.

  • Environmental conditions: Considering the environmental conditions is also crucial before the unit's installation. For instance, you cannot install it at a place receiving direct sunlight for a prolonged time. Solar energy can damage the internal coils and other mechanical parts, rendering them inefficient.

  • Closeness to the evaporator: Another important factor is the distance between the evaporation and the condensing unit. It needs to be as less as possible to avoid pressure loss. The evaporator and condenser work in conjunction to expand and compress the refrigerant. That’s how the entire refrigeration system can attain the desired temperature set.

  • Leveling: Consider the condensing unit's level with the evaporators. In other words, these units must be at the same level to maintain appropriate refrigerant flow. Keeping the former above or below the evaporator can cause a significant decrease in pressure.

  • Uniform surface: If you choose an irregular surface for condensing unit installation, expecting maximum durability won’t yield enough results. So, try to select a strong and rigid wall with a leveled surface so the unit sits properly without any wobbliness.


With the abovementioned conditions, installing the condensing unit at an appropriate place won’t be difficult. There are several other factors to be considered. But those depend on the unit type, weather, climate specifications, and expected energy output.
