Sooner or later, your heating, ventilation and air conditioner system will wear out. It may sputter its way to oblivion via a series of expensive repairs, or it might just suddenly give up the ghost one day after a decade or two of loyal service.
If your thermostat isn’t properly placed you may have pockets of hot and cold air in your home or business.
For example, a thermostat next to the kitchen and laundry room will pick up the heat generated by ovens and clothes dryers. The thermostat won’t realize the temperature may be quite different in other rooms.
