Central air conditioners

Central air conditioners are the most common type of HVAC system used in homes. A large central unit takes up a significant amount of space outdoors while cooling indoors by blowing air over refrigerated coils.

While this type of system might be cost-prohibitive for some, it provides excellent cooling power with an even flow throughout each room. It’s also possible to add evaporative coolers to control humidity in dry climates.

Ductless split systems

Ductless split systems are a popular choice for those looking to cool their home without the need to install new ductwork. With this type of system, a main outdoor unit is connected to a wall switch with a compressor and a fan inside the walls on the other end.

Indoor units usually have one or two vents that blow air over refrigerated coils like central air conditioners. Although these types of systems can be more expensive initially, they can sometimes provide additional benefits such as heating in addition to cooling, particularly if they’re hooked up to an indoor furnace unit.

Packaged terminal air conditioners (PTACs)

They are designed for high-volume applications typically found in hotels and motels. These units feature a large outdoor unit complete with wheels, cooling the entire room rather than just one area like central air conditioners and ductless split systems.

Packaged terminal heat pumps (PTHPs)

They provide both heating and cooling functions through an energy-efficient system. They’re located indoors next to where the heat or AC is needed instead of outside like other types of home HVAC systems. Since these systems are indoors, they don’t need to be as large as the other HVAC systems. PTHPs also include heating and cooling coils for each system.

While this type can initially cost more than others, it’s an energy-efficient option that doesn’t require constant upkeep like other types of HVAC systems.

Window units

There are several different types of window units available for those who choose not to go with central air conditioning or ductless split systems due to their uninviting exterior appearance. These compact units can easily mount through a standard-sized window without taking up too much space in the room.


Choosing the right HVAC system type can depend on several factors, including budget, indoor and outdoor designs, and desired location. Keep these HVAC systems in mind as you start looking into your options to ensure that you get exactly what you need for your home or business.
