The main reason to have your air conditioner cleaned is to extend the life of the unit and to prevent costly repairs in the future. A properly maintained unit is a well-functioning unit. When the individual components of your system are appropriately calibrated and cleaned, the unit runs more efficiently and utilizes less energy. Additionally, seemingly minor problems can quickly turn into costly repairs if left unchecked. A common occurrence is a filter clogged with debris that goes unnoticed, leading to diminished air flow to the compressor and its insufficient cooling.
