How Do HVAC Systems Work?

Thursday, September 1st, 2016

HVAC systems function to control the temperature and humidity inside your home while maintaining a healthy air quality. These are the basic functions of every HVAC system, but how do these machines work? There are many types of HVAC systems that function differently, but all should give you the same results. However, some HVAC systems are more effective than others, depending on your area and the climate. The following is a look at the different types of HVAC systems and how they work, including split systems, ductless systems, and furnaces.

Split air conditioning system

A split air conditioning system is referred to as split because it has components both inside and outside of the home. This type of unit is also referred to as a central air conditioning system. The system consists of an outdoor section with a compressor and condenser. A split system also has an indoor unit, an evaporator coil, and a fan.

Split HVAC systems remove warm air from the home and cycle it back through supply and return ducts as cooled air. This is accomplished when the compressor sends refrigerant through the system. This process collects heat and moisture inside your home and removes them when warm air is blown over the indoor coil, cooling the air.

Ductless air conditioning system

A ductless system, also called a mini-split, has components located both inside and outside the home as well. Unlike most traditional split HVAC systems, a ductless system does not rely on ducts to move air through a home. This type of system was made to cool or heat a single room, an addition to your home, or a particular zone that cannot accommodate ductwork.

Ductless HVAC systems also consist of a small outdoor condensing unit and a compact indoor unit. The indoor unit hangs on the wall to direct and control airflow. The outdoor and indoor components are connected by electrical wiring and copper tubing instead of ducts.

Furnaces and air conditioning systems

Modern furnaces are much more advanced than those of the early 20th century and are often matched with split-air conditioning systems. These HVAC systems do a great job of keeping your home comfortable during wintertime. The furnace fan is used to assist the air conditioning system by circulating cool air during warm seasons.

Gas furnaces produce heat by combustion of natural gas within the burner. The heat passes through the heat exchanger. Next, air from the return ducts of your home is blown over the heat exchanger creating warm air. The furnace blower will then push the warm air back into your ductwork and disperse it evenly throughout your home.
