Now that you know the basics of HVAC systems, it is time to learn more about the types of HVAC systems that can be used in buildings. Your HVAC system is very easy to use but do you know there are four different types of HVAC systems most commonly used in residential and commercial buildings. You know how to operate your system but do you know the ins and outs of your system? Many homeowners are oblivious about the type of system they have installed in their house. While this may seem trivial, it’s essential when seeking repairs or when replacing any piece of equipment. To ensure you know as much as possible about your HVAC, let’s start with the fundamentals. Read more below about the types of HAC systems that can be used in buildings:
There are 8 main HVAC components which work together. To keep the environment inside your building clean, comfortable, and safe for breathing.
These 8 main basic HVAC components include:
The thermostat is normally the most visible part of your HVAC structure. Mounted on a common wall, it should be either programmed ahead or set manually to keep the house at the desired temperature. Once the desired temperature of the room becomes too cold or too hot, this thermostat can prompt the heat exchanger or the evaporator coil-condensing unit to start circulating hot or cold air as required.
The furnace is the key component of your HVAC system. It’s also the biggest so it requires substantial area. The furnace is kept usually in the cellar or the basement. Its function is to heat the air which is to be distributed to the rooms of your home via the HVAC. This heating method is accomplished using one of four potential heat sources — combustion (burning gas, oil, coal, or propane), resistivity, heat pump, or solar power collected on site.
3. Heat exchanger:
The heat exchanger is a component fitted inside the furnace. This part switches on when the furnace is activated by a thermostat to provide warmer temperatures in winter. The heat exchanger pulls in cold air, heats it, and circulates the heated air using the ducts and out through the vents to all the rooms
4. Evaporator coil:
The evaporator coil works exactly opposite to what the heat exchanger does. It cools the hot air when your thermostat is set to lower temperatures in summer. It is placed in a metal enclosure on the furnace’s exterior or to the top or side. The evaporator coil works like an automobile radiator to produce cool air, which is then circulated all the way through the ductwork.
5. Condensing unit:
The condensing unit is connected to the evaporator coil. This unit is installed by HVAC contractors on the outside wall of your home and is filled with refrigerant gas. Once the refrigerant has been cooled to a liquid by heat exchange with the outside air, the condensing unit pumps the liquid to the evaporator coil to be evaporated into a gas once more. This is one of the esential HVAC components.
6. Refrigerant lines:
These refrigerant lines carry a refrigerant material to the condensing unit vaporized in the form of a gas and return it to the evaporator coil in liquid form. These “lines” are actually thin tubes manufactured from a sturdy heat- and cold- resistant metal such as copper or aluminum.
Ductwork refers to the system of ducts that transports the air warmed or cooled by the system to the various areas of your home. Ducts are usually made of lightweight aluminum, which is easier to install for the HVAC contractors. However, they may also be made from steel, versatile plastic, polyurethane, fiberglass, or fabric.
The vents are the rectangular outlets which transport the heated or cooled air from the duct system into the individual rooms of your home. Manufactured from high- and low-temperature safe metal, the vents are situated on or close to the ceiling and are typically have angled slats on the front. These slats direct the treated air downward to the areas which used most of the people. The vents can be usually manually controlled or even closed, to regulate the amount of heating or cooling as per the area of the room to which it will be directed.
So these are some of the most basic HVAC components, which will help you understand how HVAC systems work. These components are the base of any HVAC system and should chosen carefully. And installed by a certified HVAC technician to reduce wastage of money and time.
What is HVAC?
The full form of the term HVAC is “heating, ventilation, and air conditioning”. This term is generally used for describing the air inflow and outflow system of a building. HVAC System is an important part of all residential and commercial buildings. As maintaining the right temperature, airflow, and ventilation is a must as per the norms of safe and healthy building conditions. The term HVAC is common includes the design, construction, operations, and maintenance of the air system of a building and comprises of linked processes like humidity control, temperature control, removal of moisture, odors, smoke, dust, and regulation of heat along with air circulation.
History of HVAC:
The earliest recorded history of HVAC systems dates back to the time when Egyptians, Greeks, and Indians. They used to control the temperatures around their establishments using human-powered fans, basement furnaces, and rope fans in the year 1000. After a few hundred years, chimneys were invented which used widely until today. It is said that Leonardo Da Vinci invented a water-driven fan to aid in indoor ventilation.
Stove heating systems were invented in the year 1800 by Benjamin Franklin. Also, the steam engine and latent heat were other vital discoveries in that period. The modern day era started with significant developments in the field of thermodynamics by James Joule and Carnot. Which gave way to the development of the modern commercial and home HVAC systems. That we use today which include floor heating panels, solar power-based systems, and hydronic circulator pumps.
Modern-day HVAC systems vs. Old HVAC systems:
The modern day HVAC systems are much more efficient and cost-effective as compared to older models. And use advanced pieces of equipment to do much more than just heat or cool your living space. They also ventilate your home, clean the air using internal air filters and work towards saving energy by being environment-friendly. Modern systems are also easier to control as compared to primitive HVAC systems. As system control is a major field on which many modern HVAC research studies are based upon.
It is also easier to maintain the modern systems. As there are many small issues that can solve easily by the building owners themselves without the help of any certified HVAC technician. Commercial HVAC systems, however, require some external help in most cases as they involve large-scale operations and complex equipment.
Modern HVAC industry functions around the design and construction of the home and commercial HVAC systems, repair and maintenance, equipment sales, and research. There are many regulating agencies which keep a check on the practices. Being followed in the industry and how to improve them.

Why installing an HVAC system is important:
HVAC systems have been long used in residential and commercial buildings. But it is important to know why this system is important. The basic usage of HVAC systems arises from the need to live in a comfortable and temperate environment. Places which witness extreme climates with chilling winters or burning summers feel the need to control their indoor climate so that the people living or working inside the building can be comfortable inside the building. The HVAC system regulates the temperature of the air inside your home or office and heats it or cools it to bring it to an optimum temperature. It also reduces the spread of airborne bacteria and viruses as they cannot survive easily in temperate climates.
Installing this system also helps you maintain natural or forced ventilation inside the building which is a must for keeping many respiratory or virus-borne diseases at bay.
