The basic theory of heating and cooling a house or building is based on the knowledge that cold air is heavier than warm air and settles near the bottom of any space. With this information in hand, air conditioning and heating installation has been studied to gain the most efficiency of modern equipment. Typically, under the name of HVAC, heating, ventilation and air conditioning, engineers look at a building and determine the best path for the tempered air to take.

When heating units were first installed in homes and buildings, they counted on gravity to circulate the air. Furnaces were placed in the bottom of a building with ductwork installed to carry the heat to the upper level. As the air in the upper levels cooled, it was moved by gravity through separate, cold air ducts, back to the furnace where it would begin its cycle over. Using that theory, air conditioning and heating installation contractors can design a system to utilize gravity, as well as forced air movement, to maintain a building's comfort level.

Depending on the heat source of a furnace, most communities regulate who is allowed to install furnaces, requiring either a licensed electrician or certified plumber to complete the air conditioning and heating installation to insure it will present no danger to the building's occupants. While just about anyone can fasten parts into place, not only is the efficiency in jeopardy, a faulty air conditioning and heating installation can also put the people in danger.
