Do You Know the Five Most Important HVAC Parts in Your Unit?

You may have heard the terms for various HVAC components, such as the evaporator coil and the blower motor, but do you know exactly what they do? Although you should always call a reputable HVAC technician for servicing, it never hurts to learn about how your equipment works. Therefore, we thought it’d be a good idea to take a look at five of the most important HVAC parts of your system.

Heat Exchanger

Based on the name of this component, many people are surprised to learn that both their furnace and air-conditioning system include a heat exchanger. In a furnace, the heat exchanger absorbs heat and warms the air before it’s transferred throughout your home. In an air conditioner, on the other hand, this component removes heat from inside your home and transfers it outside, making it one of the most important HVAC parts there is.

Blower Motor

The blower motor works in conjunction with the heat exchanger. Once the heat exchanger has increased or decreased the temperature to whatever your thermostat is set at, the blower motor switches on a fan that moves the warm or cool air around. A variable blower motor has the ability to monitor the equipment and run at a variety of speeds for better airflow control.


Your home’s thermostat is basically the central hub of your heating and cooling system. Dial the temperature up or down to determine when the system kicks on. Modern thermostats are smart, meaning that they have advanced features and can even learn from how you use them. If you haven’t already upgraded your existing thermostat, now’s the time, as it is definitely one of the most important HVAC parts.

Evaporator and Condenser Coils

Your system’s evaporator coil works by creating a cool surface in your system. When air moves over this surface, it’s cooled down before being dispersed throughout your home. The condenser coil, typically located outdoors, helps release heat from the inside of your home.
