Many people are already familiar with the HVAC system and what it does. You probably already know that HVAC stands for Heating, Ventilation, and Air Conditioning too. The system contains a heating component that keeps the home warm during the cold winter months, and a cooling component keeps the indoor space cool during the hot summer months. But how do these units do it? The HVAC Service, a leading HVAC company, lends insight into the process.

How HVAC System Works

If you’re wondering how your HVAC system has maintained your indoor comfort all year round, here’s where you get the answers. HVAC systems are designed for three main interrelated functions. To promote thermal comfort, improve air quality through air filtration, and dehumidify the air.

The HVAC system leverages its nine important parts to deliver on these three functions. These parts are responsible for air exchange, filtration, dehumidification, heating, and cooling.

Air Return: Air return is an important part of the HVAC system. This component marks the beginning of the ventilation cycle. It sucks in air from the environment, forces it through the filter to clean it up, and then passes it into the main system. 

The action of the air return system is responsible for the buildup of dust and dirt in the air filter. It is recommended that you clean and replace the filter at intervals to promote high indoor air quality.

Filter: As described above, the filter acts as a barrier and filtration chamber between external air and internal air. The filter is designed to sift through the smallest macromolecules of air, trapping spores and allergen and letting air through it. During maintenance checks, air filters should be changed to improve indoor air quality and prevent allergic reactions.

Exhaust Outlets: The exhaust outlet is designed specifically for the heating system. It is responsible for pushing out the exhaust created during the heating process. This part of your HVAC system is likely to gather debris over time, so it is recommended that you perform annual checks on your vent stack or chimney flue.

Ducts: The ducts are like passages or channels that transport and deliver warm or cool air across the home. The ducts ensure that all connected areas within the home get a fair share of the appropriate temperature. It is also one of the common culprits to watch out for when areas within your home aren’t receiving adequate warm or cool air.

Air duct problems can cut off some parts of the home from cool or warm air. It can also get clogged with debris or other materials.

Electrical Elements: This includes all of the electrical parts of the HVAC system responsible for its control and operation. This is usually one of the suspect parts when your HVAC won’t come on or function properly. 

Outdoor Unit: The outdoor unit is designed to be placed outside your home and functions to pass out warm air during the cooling process. The outdoor unit is usually equipped with a fan that provides airflow. It is important to ensure that nothing gets in the way of your outdoor unit. Ensure that it is installed in areas free from rodents, ventilations, and other pests.

Compressor: The compressor is one of the most important parts of your HVAC system. It controls the entire cooling process by converting refrigerant from a gaseous state to a liquid form and sending it to the coils. The refrigerant is often the culprit when your cooling unit won’t work or is making strange noises.

Coils: The coils are located in the outdoor unit and connect the outdoor to the indoor unit. They are responsible for converting warm air into cool air with help from the refrigerant. Coils can often freeze up during the winter season. It is important to keep them adequately insulated to prevent this. Once frozen, it’s recommended that you contact an HVAC technician to prevent refrigerant leaks.

Blower: Blowers are designed as part of the outdoor unit. They trap warm air and pass it through the system.

What is Included in an HVAC System?

HVAC systems are designed to carry three important units. They include;

Heating unit: To keep the indoor space warm during the cold winter months

Cooling unit: To keep the indoor space cool during the hot summer months

Ventilation element: To maintain indoor air circulation.

What is the difference between HVAC and Air Conditioning?  

There’s a huge difference between HVACs and Air Conditioning units. HVAC systems are a combination of heating, ventilation, and air conditioning units. They are great for heating, cooling, and maintaining indoor ventilation. On the other hand, air conditioning units are standalone equipment for cooling.
