Tennessee is known to have a fairly temperate climate with temperatures between 67°F and 89°F throughout most of the year. However, there are numerous climatic conditions that may be experienced due to the wide range of geographical features and varied topography throughout the state. Tennessee is highly susceptible to tropical storms during the summer and fall months but is also subject to below freezing temperatures during the winter in northeastern portions and areas with mountainous terrain. It has been reported that Tennessee can experience temperature extremes ranging from under 20°F to above 90°F. Thus, professionals with a Tennessee HVAC license are essential for ensuring comfortable living and working conditions during the muggy summers and bitterly cold winters.
