The thermostat in your Arizona heating and cooling system may be small, but your system can't function properly without it! A thermostat works in conjunction with your air conditioner or heater to help the air conditioner know when it needs to kick into gear or when it has done its job to heat or cool the room.
Here's how a thermostat works.
First there is a main switch that determines whether your AC system is off or on. Then there is a switch that allows you to choose either the "cooling" or "heating" mode of the unit. Most thermostats also have a "fan" setting on the switch that allows you to turn on the fan in the air handler and just simply circulate air without heating or cooling it.
Inside the thermostat is a thermometer coil of two thin metal strips that have very sensitive expansion and contraction rates, allowing them to respond quickly to temperature change. When the surrounding air is cooled down, one of the strips contracts and pulls the mercury switch so that the air conditioner shuts off. Once the air begins to heat up again, it expands and the switch turns the air conditioner back on to maintain the desired temperature.
These same elements work to maintain temperature when the unit is in "heat " mode.
Rainforest Plumbing & Air technicians are trained to fix or replace thermostats. Since the thermostat is an electrical device, it can break or cease to function properly. When this happens, you can give us a call to schedule service right away so you can turn on the air!
