The air duct system isn’t as simple as some lead you to believe. Its cleaning isn’t fast or cheap, and if you hire a contractor who promises that, then you will waste your money on nothing. We will give you a list of HVAC parts and explain to you what each of them represents. We hope that you will realize how extensive this system is and why it’s so expensive to clean it properly.
Essential air duct system elements
These are the core elements of the HVAC system. We might go into details with some of them so you could understand some differences between them and alternatives that exist.
Vents are installed in the building upon its construction. There is the option to install later, but that makes it harder to hide them within the construction of the wall. They disperse the warm/cold air into rooms. They are usually rectangular and metal so they can withstand various changes in temperature.
Air ducts conduct the air throughout the building from the furnace to vents that channel it in different rooms. Some ducts have dampers which allow owners to regulate the flow of the air and thus increase or decrease the amount of hot/cold air that goes through the system.
A furnace in a large building is huge, and it is usually located in the basement. Different types of heaters exist; some are filled with steam, some with air and some with water. It pushes the air into the air duct system.
Heat Exchanger and evaporator coil have similar purposes, one supplies the pipes with hot and the other with cold air. Heat exchanger pulls in cold air in, heats it and returns it the building, and the evaporator coils do the opposite.
Other HVAC system elements
Other items that are essential in this system include a thermostat, condensing unit, and refrigerant lines.
The thermostat is a remote controller of the HVAC system, and it allows the owner to set the temperature they want. Every room has one of these, and you can set different temperatures in every room. Every thermostat is located on the wall unless the owner asked for something else.
The Condensing Unit turns the air into liquid and sends it to the furnace through refrigerant lines. This liquid is the source of cold air the HVAC creates. The liquid travels through those lines to the coil, and from there it’s spread with small nozzles which allow it to turn back in gaseous form.
