HVAC, or heating, ventilating, and air conditioning, is a term that deals with the climate
control of a structure. In some regions of the world, HVAC will also be used to refer to
electrical issues and plumbing. The heat, ventilation, and air conditioning of a structure are all
interconnected. The goal of HVAC is to provide an architectural structure with a high
quality of indoor air, as well as excellent thermal properties and competitive installation
costs. A system that is built with HVAC properties can also reduce the amount of infiltration that
is present in a structure. In most modern buildings, either one or multiple HVAC systems will be
used. If the building is fairly small, the construction company will generally select specific
HVAC systems that can be efficiently used with it.

For a building that is large, the construction company may need to use engineers who work in the
building services field. Engineers who specialize in a number of fields may be used for these
tasks, and they may be responsible for dealing with mechanical or structural issues. The
engineers will play an important role in the design of the HVAC system. When an HVAC system
is installed, it is mandatory for construction companies and engineers to make sure they are
following the building codes, and they must also have the proper permits. There are a number of
units that are comprised within HVAC. Some of them are fan coil units, air handling units, and
makeup air units. The fan coil unit is a small structure that acts as a blower, and it will
commonly be used in hotels.
