What Is An HVAC System & How Does I Work
We have all heard about the term HVAC system and have a general idea of what it means; however, do you know what an HVAC System is and how it works?
Understanding how your HVAC system works will allow you to save money in repairs and identify when maintenance is needed and the essential parts you should look out for. At Kay Heating and Air Conditioning, we’ve seen how several homeowners and business owners get tricked and often overcharged on HVAC services in Greensboro because they don’t know how their system works.
In this article, we’ll provide you with the needed information to better understand your heating and air conditioning system and, next time, pay a fair price on repair or maintenance.
What Is an HVAC System?
HVAC stands for Heating, Ventilation, and Air Conditioning. HVAC Systems use technology to draw air from one space to another, usually from the outdoors to the building’s interior. The air gets either heated or cooled, depending on the weather conditions, for optimal comfort.
HVAC systems are also used in submarines, family homes, trains, planes, and any other space where fresh and clean air is needed. The ventilation part of the system also filters the air, removes bad smells and air allergens, and provides optimal indoor air quality.
How Does An HVAC System Work?
There are different types of HVAC systems; however, they all follow the same concept. Whether they are cooling or heating air, they force the air through metal ducts using a blower. All HVAC systems have six main parts:
1. Thermostat
The thermostat acts as the brain; it measures and controls the temperature and triggers the HVAC system to start working when the weather is too cold or too hot.
2. Air Vents
The air vents distribute the cooled or heated air into the different spaces of the home or building. If the system is centralized, the air vents are usually found in the ceiling.
3. Furnace
The furnace is responsible for heating air, and it’s the part that requires the most space. There are different furnaces; some may heat the air through solar energy, others through combustion, electric resistance, or heat pumps.
4. Evaporator Coil
The evaporator coil is responsible for cooling down the air whenever the thermostat identifies that it is too hot.
5. Condensing Unit
The condensing unit is an integral part of cooling the air, and it works hand by hand with the evaporator coil. The unit gets filled with refrigerant gas. During the cooling process, the gas turns liquid, and the condensing unit pumps it into the evaporator, transforming the liquid back into gas.
6. Refrigerant Lines
The refrigerant lines move the refrigerant in the form of gas to the condensing unit.
Taking Care Of Your HVAC System
The six parts mentioned above are the ones you need to take care of during each maintenance to ensure your HVAC system performs well and avoid expensive heating and AC repair.
