What is a HVAC and How does it work? from jakson lee's blog

HVACis a common term that people use, and most have a general idea of what it's referring to. On the other hand, what exactly does HVAC mean? And, how does it apply to your home? Petro Home Services provides full home services in addition to our HVAC solutions, and we can give you the lowdown on HVAC basics.


What is HVAC?


HVAC stands for Heating, Ventilation, and Air Conditioning. HVAC refers to the different systems used for moving air between indoor and outdoor areas, along with heating and cooling both residential and commercial buildings. They are the systems that keep you warm and cozy in the winter and feeling cool and fresh in the summer. They also are the systems that filter and clean indoor air to keep you healthy and maintain humidity levels at optimal comfort levels.


How does HVAC work?


Each component in your home may be separate, such as a radiant system combined with window air conditioning units. However, it is more common for combined systems such as central heating and AC systems that use a single blower to circulate air via internal ducts in a home, or with a ductless system for different rooms or zones in the house.


HVAC Basics.

The purpose of an HVAC system is more than just warming or cooling a space. Instead, it serves to improve indoor air quality and provide comfort for everyone inside a building. While there are several different types of HVACsystems, they all begin with the same essentials.


First, there is a source of fresh air intake from the outside or from within the home. This process is called ventilation, and it happens in two different ways. Natural ventilation is present in most homes and refers to the way air typically moves in and out through windows, doors, vents, and other openings. This exchange of air is necessary to replenish oxygen, and to remove odors, carbon dioxide, and excessive moisture.


Mechanical ventilation uses a mechanical system--the V in HVAC--to move air in and out. In the past, there was plenty of natural ventilation in most homes from gaps and cracks in the construction along with opening and closing of doors. However, modern construction is creating homes that are far more tightly sealed so ventilation is becoming an increasingly important component in home HVAC systems. Once the air is brought in, it is drawn into an air handling unit where the work begins. Here, air is drawn through filters to remove dirt, dust, allergens, and other particles.


Next up, is comfort. Air is either sent to be heated or sent to be cooled and have excess humidity removed. Once the air is clean, fresh, and at a comfortable temperature, it is directed into the home. For central systems, this means moving through a network of ducts and registers to different rooms. For other systems, this usually means being directed right into space.

 

The three main functions of an HVAC system are interrelated, especially when providing acceptable indoor air quality and thermal comfort. Your heating and air conditioning system is often one of the most complicated and extensive systems in your home, but when it stops working you’ll know soon enough! There are nine parts to your HVACsystem that you should be familiar with: the air return, filter, exhaust outlets, ducts, electrical elements, outdoor unit, compressor, coils and blower.


Air Return

Your air return is the part of your system that marks the starting point of the Ventilation cycle. This return sucks in air, draws it through a filter, and then passes it into the main system. Pro tip: Make sure to dust your returns frequently as debris and dust can easily build up on your filters.
