HVAC is the acronym for “heating, ventilating and air conditioning.” HVAC in Chicago allows the homeowner to regulate and control the interior temperature of the home, and it can be done from one location; the thermostat. Before the advent of modern, multi-use systems the home was heated or cooled room by room rather than from a central system that affected every room in the house at the same time.
A typical HVAC unit cools the interior of a home or other structure by extracting the warm air from a space, pulling it through a series of ducts and passing it over refrigerated coils. As the warm air passes over the cold coils, the heat is transferred to a coolant which runs through the coil. A fan blows air across the cold coil, sending cold air back through a different duct system to the various rooms in the home.
As air which is now cooled is being sent back to rooms via the ducting, the refrigerant which has now been heated is sent to another component which is normally located outdoors. It is in the outdoor unit where heated coolant passes through another set of coils and fan. The fan blows over the heated coil cooling it, the now cooled refrigerant is returned to the inside components where the entire process is repeated ad-infinitum.
When HVAC in Chicago systems are called upon to heat the interior of a building, the process is similar to cooling. Air is pulled into the system through return air ducts, the air passes through the system where it is heated rather than cooled. The heat is generated by a furnace and heat exchanger. The now heated air is forced through other ducts, assisted by a fan or blower.
The primary function of any HVAC system is to heat the home in winter and cool it in summer, but it does more than that. HVAC in Chicago also filters the air far more effectively and efficiently that any simple ventilation system does. As the air travels through the system of ducting it passes through filters which remove a great deal of airborne contaminates such as dust, pollen and mold spores. The consistent air movement contributes to improved air quality, as the air circulates and is constantly mixed with fresh air, odors and a great deal of the moisture in the air is also removed. A combination of effective filtering and fresh air improves the air quality far better than a system which simply re-circulated.
