Heating and cooling fall under essential facilities in countries with extreme temperatures like the USA. These are in residential buildings, malls, shops, gyms, and workspaces. Further, the optimum temperature in the office is the bare necessity that the employer should provide to all employees. For this, one needs the commercial setup of an HVAC system. What is different about this system is the size. The residential units are small and compact, while commercial units are massive. So, business owners can consult professional service providers, such as HVAC Companies in Lorton VA, for the best deals and insights.

HVAC, or Heating, ventilation, and air conditioning, is a system providing the cooling and heating effect to a closed space. The commercial setup is suitable for large settings like offices, restaurants, banquet halls, etc.
Here are the main operational parts.
Thermostat
It is the primary control for the system. It sends signals to the setup according to the settings chosen by the user.
Furnace
It gives off heat, as the name suggests. It is the giant of the entire system.
Heat exchanger
It is located in the furnace and heats up the air sucked into the furnace.
Refrigerant lines
These are in the form of pipes that convert gaseous refrigerant into its liquid state.
Vents & ducts
These transfer the cooled or heated air into the space (office, restaurant, halls, etc.).
Working of HVAC
The three main processes running the unit are heating, cooling/ conditioning, and ventilation. Each one has a dedicated unit, and they come together to form the HVAC unit as a whole.
Heating
The thermostat initiates the healing process by sending a signal to the furnace. The burner generates the required heat and works with the heat exchanger to turn it into hot air. The motor and fan in the furnace distribute the heated air and sends it to vents and ducts. Finally, the space gets warm and comfortable.
Cooling
The AC in the HVAC takes care of this part. It uses a refrigerant to absorb the gas heat and cool it down. The compressor converts the high-temperature gas to liquid and sends it to the condensation coil. The coil cools it down and sends it to the blower. The blower/ fan distributes the cooled air and sends it to vents and ducts. Finally, the space gets relaxed and comfortable.
Ventilation
It is crucial as heating and cooling would be useless without proper circulation. It regulates the amount of air in circulation and keeps the place free from foul smells, molds, etc.
