Do you know what makes up the working parts of your HVAC system? If not, you may be in for a surprise when it stops working. Worse, without knowledge of how HVAC systems work, fixing or replacing parts may be impossible.

In this article, we’ll cover the basic parts of HVAC system with a focus on the main components. You’ll be a heating and air conditioning employee that any homeowner, building manager, or HVAC specialist will be proud to know. Read on!

Heating Elements

An HVAC system is a complex assembly of various components that work together in order to regulate the temperature of a space. In regards to heating elements, some basic parts will usually include a furnace, blower, and ductwork.

A furnace is the main component that is responsible for producing heat. The blower is used to distribute the air through the duct system.

The ductwork is a network of ducts that carry air from the blower to the different rooms or the vents. The heating elements of the system are inside the furnace and can vary from one system to another.

Air Conditioning Components

At the core of the system is the air handler, which circulates air through the ductwork to reach various areas in the home. This air is then conditioned with the help of a furnace, thermostat, air filter, and other ancillary components.

The thermostat is used to control the temperature of the air being circulated, while the filter helps to purify and improve air quality. The furnace is the primary source of heat, which is supplied through burners that are fueled by natural gas or propane.

Condensers and Coolers Used

An HVAC system typically consists of two main parts; the indoor and the outdoor units. The indoor unit includes an evaporator coil, a condenser, a thermostat, and a fan.

The outdoor unit comprises an outdoor compressor, condenser fan, and a cooling system. Condensers and coolers are necessary components of an HVAC system as they help to reduce the temperature of the air in the house.

The condenser on the outdoor unit will draw in the hot air and extract the heat from it due to the cold coils. The cooler inside the home takes that warm air and uses it to cool the air before being released back into the house.

This helps the system to maintain the desired temperature inside the house and keeps the temperature consistent.

Humidifiers & Dehumidifiers

An HVAC system includes the major components of heating, ventilation, and air conditioning. There are accessories or additional components that are often included, such as humidifiers and dehumidifiers.

Humidifiers are used to increase the humidity in the air in order to control and prevent allergies, colds, and flu. Dehumidifiers are used to reduce and/or eliminate the moisture in the air, thereby preventing mold and mildew from forming.

Both pieces of equipment help to regulate the environment inside the home, business, or building and can be an essential part of a healthy HVAC system. So to ensure your property is operating at its best, AC repair or regular maintenance is recommended.
