HVAC systems are nowadays present everywhere, in our homes, in our offices, in our stores, ensuring our thermal comfort, heating the air in winter and cooling it in summer, yet most of us pay no or very little attention to them. However, to be a responsible homeowner, you need at least some basic understanding of how these essential systems work, so here are some details for you:
- The heating process – most HVAC systems in homes today are forced air systems that use a furnace to heat air and ducts and in-room vents installed around the house to disperse the heat;
- Ventilation – HVAC systems also move and filter the air in the building, controlling its quality a well as the level of moisture in the air. Most HVAC systems use multiple filters to purify the air circulated in the building, removing allergens, volatile organic compounds and other airborne impurities;
- The cooling process – most AC systems use some type of refrigerant to cool the air in the indoor space. The unit collects heat from the air and expels it from the building. The liquid created through the process is also evacuated, that’s why many HVAC units have ducts protruding through the building’s exterior wall and dripping water.
