Window or Wall systems cater for smaller areas which can be sealed off by a door.  These systems include basic units for cooling only and more versatile reverse cycle systems for cooling and heating.

An example of effective use could be a games room in a detached garage. Other uses could include a semi-detached home office, a medical or dental surgery or even a clinic/treatment room for one of the many paramedical fields.

 

These units use ordinary household power and are relatively easy to install in an existing window or wall space.  They are easy to maintain and are quite economical to run for their size.
