Thermostats

Simply put, a thermostat is a control mechanism. These are most commonly found in a centrally located area within the home. Thermostats act as the user interface for a central air conditioning system. Thermostats can tell the ambient air temperature and determine whether to turn the air conditioner on or off dependent on its settings. In the old days, thermostats contained mercury and used mechanical means to connect electrical circuits which sent an on or off signal to the air conditioning or heating system. Now, thermostats have the ability to use more complex circuitry and even wireless technology to turn the comfort system on or off. Homeowners can now turn their air conditioner on from across the globe!In essence, an air conditioning system moves refrigerant from two main areas: the outdoor unit (compressor and condenser coil) to an indoor unit (the evaporator coil). Heat is absorbed from the air inside of the home and released to the outdoors as the refrigerant moves from a gaseous to liquid state within the refrigerant lines,
