HVAC and Air Conditioning Installation Explained



A heating, ventilation and air conditioning (HVAC) system includes the technology and parts installed in a home that control the indoor climate, temperature and air flow. An air conditioner is one part of an HVAC system. Air Control of Northwest Arkansas installs, services and repairs HVAC systems and air conditioners.


If you are building a home or need to replace an HVAC or air conditioner, this article explains the process of installation. The information below dives into how a technician installs a HVAC system or air conditioner.


The installation of an HVAC system is a complex process, often completed during the construction of a home. Typically, specially trained technicians install HVAC systems and air conditioners. Described below are more details on the process of installation.


Types of HVAC systems


There are four HVAC systems typically installed in homes. Each of these systems requires different installation processes. The four common types of HVAC systems are:

  • Split System

  • Ductless Split System

  • Packaged (Gas/Electric, Heat Pump, Air Conditioning and Hybrid)

  • Geothermal


Split System


A split HVAC system means one component resides inside the home and another sits outside the home. A split HVAC system remains the most common HVAC system installed in homes. You can identify a split HVAC system by an outside metal box air conditioning unit and a component housed inside the home.


The outside unit is the air conditioner condensing unit. The inside unit is the air handler or furnace (typically a gas furnace). The furnace houses the evaporator coil and blower, which capture heat and send it through the ductwork by refrigerant lines. These copper refrigerant lines connect the furnace to the air conditioner unit.
