Your first question is who to call for HVAC installation and HVAC service in Chesterfield. The professionals at Mode Comfort & Air Quality are ready to answer these questions and more.

How did the marvel of air conditioning come to be?

The humble air conditioner was named one of the top ten greatest mechanical engineering achievements of the 20th century, according to the American Society of Mechanical Engineers. Most of us gloss over the stunning scientific achievements of HVAC and just want to be comfortable. Ding Huane in second-century China also wanted to be comfortable when he devised a manually powered rotary fan and began the movement toward cooling the air around us. A few centuries later, Benjamin Franklin conducted experiments in 1758 with evaporation and alcohol to attain freezing temperatures.

Cooling technology grew from the need to keep food cool to reduce the growth of bacteria. Experimentation in 1824 showed that liquefied ammonia could chill air when it is allowed to evaporate. Dr. John Gorrie created ice in 1842 using compressor technology. These mechanical refrigeration ideas led a skilled engineer named Willis Carrier to experiment with air humidity control in 1902. He was seeking to solve a problem with air cooling at a printing plant. It turns out air conditioning was first developed to cool air for industrial purposes and not our personal comfort.

Willis Carrier developed a system to send air through coils filled with cold water that cooled the air while removing moisture to reduce the humidity. In 1933, the Carrier Air Conditioning Company of America began manufacture and sale of a belt-driven condensing unit with blower, evaporator coil, and mechanical controls. In 1928, Thomas Midgley, Jr. discovered the use of freon as a refrigerant, and in 1930, the White House became air-conditioned. Today, 87% of residences in the United States have air conditioning, 75% of which are central.

How exactly does air conditioning work?

Basically, an air conditioner works by removing heat and humidity from indoor air by returning cool air to indoor spaces and depositing undesired heat and humidity outside. The cooling system uses a chemical refrigerant and has three main components. These are a compressor, a condenser coil, and an evaporator coil. Each component works in tandem to efficiently convert the refrigerant from gas to liquid and back again. The compressor and condenser coil are located in an outside A/C unit, and the evaporator coil is inside the home.

The compressor raises the temperature and pressure of the refrigerant in its gas state and sends it to the condenser where it becomes a liquid. The liquid refrigerant goes back inside to the evaporator coil where it evaporates and cools the indoor coil. A fan blows indoor air across the cold evaporator coil and heat is absorbed into the refrigerant. The cooled air is circulated throughout the home and the heated evaporated gas is sent back to the outside compressor and released into the air as the refrigerant again becomes liquid. This cycle continues until the air inside your home becomes the desired temperature. The only company you need to call for HVAC installation is Mode Comfort & Air Quality.

What is central air?

When cool air comes through vents in the floor, wall, or ceiling of your home and business, it is probably a central air system. There are several components to a central air system. A thermostat inside the home or business controls system operation. An outdoor unit contains the fan, condenser coil, and compressor. The indoor unit, usually a furnace or fan coil, houses the evaporator coil and fan to circulate the cooled air. Copper tubing allows the refrigerant to flow between the outdoor and indoor units and an expansion valve regulates the amount of chemical refrigerant traveling to the evaporator coil. Finally, a central air system contains ductwork to circulate cool air to the various living spaces of your property. A continuous cycle of heat and humidity removal from indoor air to the outside and cool air distribution inside keeps us comfortable when outside temperatures are anything but.
