A lot of professional installations involve some form of guarantee that the work will be properly done, and you will have a warranty in case something wrong happens.

To have an air conditioner properly installed is not as simple as it appears. If you do it yourself without having adequate knowledge and tools to use, you might compound higher energy bills on yourself and a lower AC functionality. A professional AC unit installer can ensure the work is done correctly and give you advice on future maintenance to make it operate at the optimum level.
