The costs related to rectifying these issues through the use of temperature switches and controls can result in significant cost-savings, as risks of down-time and injury are minimized. Air compressors are not very expensive to repair, and the cost of repairing a compressor is usually much less than the cost of replacing a compressor. Ambient temperature too high or not enough ventilation: The compressor needs a certain amount of airflow to keep it cool, and if the ambient temperature is too high or there's not enough ventilation, it can cause the compressor to overheat and shut down.
