Nevertheless, many homeowners are still not sure about the system and end up making the wrong choice. To help you out, we will tell you about the HVAC equipment process and how you can take care of it. So, without further ado, let’s jump right into it.

What is an HVAC System?

An HVAC system includes various gears, parts, and procedures through which you create a comfortable indoor environment for your commercial or residential property.

Some of the quintessential parts of the system are air conditioners, ductwork, heat pumps, and furnaces. In addition, air handlers, filters, and other air conditioning items are also examples of the usual equipment covered in this category.

The Main Components of HVAC System

Overall, there are a few essential parts of the system that you need to know. All of this helps it function to keep your home warm or cool as per the setting. Here is a brief rundown of all the equipment:

Air Return

The portion of your system that starts the ventilation process is your air return. The return takes in air, filters it, and then discharges it into the primary system.

Filters

Filter helps in trapping the particles such as dirt and grime when the air passes through it.

Ducts

Your ducts are the passageways via which warm or cool air moves.

Compressor

A compressor is the main part of the outer unit that plays a pivotal role in compressing and circulating refrigerant in your HVAC system.

Coils

Coils capture and transport humidity and heat in your HVAC system. They help to maintain the refrigerant’s temperature.

Outdoor Unit

When we talk about an HVAC system, outdoor units are the one part of your system that comes to mind. The exterior unit houses the fan that creates ventilation. It is a vital part of the system and needs proper care.

Electrical Components

Every main piece of HVAC equipment must be able to communicate with other parts of the system. And all of this is managed by electrical wiring equipment and controls.

Thermostats

The thermostat is the system’s gateway for user control, relaying commands across the system.

What are the Key Operations of an HVAC System?

We know what the term HVAC stands for heating, ventilation, and air conditioning, but what does HVAC do? The most crucial aspect to remember is that HVAC systems circulate air.

In general, there is a process in place to transport hot air somewhere, whether to or from the house. The heat is captured or created by the air conditioning system, heat pump, and furnace in a home and then moved by the blowers and duct.

Here is the process of each sub-system to give you a better overview of how it helps keep your home temperature as per your requirements:

Heating

A furnace produces heat by burning its fuel supply, such as gas, or using electrical energy. Also, some heating systems use the heat pump to absorb the heat from outside and then transfer it inside.

Ventilation

For releasing surplus heat to maintain a comfortable indoor environment, a chimney flue or vent stack can come in handy as part of the heating system’s ventilation. The venting system is generally organic or by force.

The usage of ventilation through force is common when there is a need for air cleaning as well.

Cooling

Many people have a misconception that the cooling system creates cold air as opposed to heating and that is not true because it functions differently.

The pumps absorb the heat inside your house after which it transfers the heat outside of your home. As a result, it brings down the temperature in your home.

Whether we talk about heating or cooling, a heat pump plays a crucial role in your HVAC system. Therefore, it is important to contact a professional to make sure your system is working efficiently.
