Air Handler (Electric Furnace)
An air handler is basically an electric furnace. They take the air around them, run it through their system, and produce cool or warm air. This is why they can sometimes be referred to as air moving units, or air mixing units. But we will stick to calling them air handling units.
You want a good furnace, from a reputable brand, that can meet your energy and heating needs. All of the controls need to work properly, along with the correct safety devices. When it comes time to change that old furnace, be sure to remember that a quality installation is just as important as the choice of a quality brand. Sometimes even more so!
In heating and air conditioning (HVAC) applications, the term heat pump normally refers to a vapor-compression refrigeration device that includes a reversing value and optimized heat exchangers so that the direction of thermal energy flow may be changed without loss of efficiency. Most commonly, when used in heating, heat pumps draw heat from the air or from the ground.
Central air conditioning systems use a condenser unit made up of three basic parts. The heat exchanger cools down incoming refrigerant vapor and condenses it into liquid. Moving that refrigerant through the system is a compressor that raises the pressure to keep the liquid flowing. Finally, there is a fan that blows air from the outside through the heat exchanger to help cool the refrigerant.
A thermostat is a component of a control system which senses the temperature of a system so that the itís temperature is maintained near a desired set-point. The thermostat does this by switching heating or cooling devices on or off, or regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature.
An evaporator coil is used in an air conditioning system to allow the compressed cooling chemical, Freon, to evaporate from liquid to gas while absorbing heat in the process. Evaporator coils need to be cleaned regularly to operate at peak efficiency.
