Heating Systems

Heating systems play an essential role for your home. Your HVAC system has multiple heating components you should be familiar with.

The furnace will take up most of the space in an average HVAC system. Usually, the furnace is located in the basement of a home. This component moves air from a heat exchanger through the air ducts. Sometimes a furnace can be confused with a boiler, but you should know that these are different.

The heat exchanger is the part of the system that actually adds heat to the air. This air enters through a combustion chamber.


AC is also an important part of your HVAC system. This is the part of the system used to cool air and move it throughout your home.

An evaporator coil moves refrigerant so that warm air can be passed over the coils and cooled. This now cool air is then moved along through the air ducts to cool your home.

A condensing unit is similar to an evaporator coil, but this component works for an outdoor AC unit. The inside of the unit exchanges heat with the air that is being passed over it. This type of unit gives off heat, whereas an evaporator coil doesn’t.

Refrigerant tubes are metal tubes that connect the components of the evaporator coil and the condensing coil. These tubes contain refrigerant.


The thermostat is an important part of the HVAC system that is used both for heating and cooling. The thermostat reads the temperature inside the house and enables you to choose your ideal setting. If the desired temperature is not met, the thermostat will signal the system to turn on and being cooling or heating the house until it is warmer or cooler.


Ductwork is another important component for both heating and cooling. This is the series of structures in the home that moves the air through the system and out of vents in order to cool or heat. The vents are connected to the ductwork.
