Is there any benefit to replacing my old thermostat?
There are many benefits. Many of the older models use liquid mercury switches. Mercury has been shown to cause health issues and HVAC contractors and equipment manufacturers are attempting to collect and properly dispose of these thermostats. The new generation of thermostats use electronics that are much more accurate, this provides for a more stable temperature in the house and reduced fuel consumption.
