The most obvious function of a condensing unit is to reduce noise and vibration. Every noise you hear will be a result of vibrations, sound waves, and the like moving around inside the structure. Since every piece of your motor home is unique in construction, it will have some aspects that will affect the sound levels. For example, a standard diesel truck has a bigger frontal area, meaning that the sound waves will travel deeper into the structure than an internal combustion engine truck.
This is why a condensing unit is one of the most popular ways to reduce noise reduction in a motor home. A unit is a box with two sides that are strategically positioned to capture vibrations and generate sound waves which are then concentrated and turned into energy which is used for powering motors and fans. Because the unit and the motor are placed away from each other, the noise reduction is enhanced.
Depending on how well a motor home was built, a condensing unit may not be required. If a motor home is built on solid ground, a unit is not needed. However, if a motor home is built on a lot, it should be considered as part of the noise reduction because the vibrations could cause damage to both the motor and the unit. In addition, if a motor home is not being driven too hard and it is already moving, a unit is not needed.
