Differences Between HVAC and Air Conditioning Systems

Many times the terms HVAC and AC are used interchangeably when you are speaking of cooling systems. In actuality, these are acronyms for two different types of cooling methods. HVAC stands for “Heating, Ventilation and Air Conditioning”, and AC stands for “Air Conditioning.” Essentially, HVAC can mean a system that heats and cools or just does one or the other. An air conditioning system simply provides cooling. The Arizona summer and winter seasons can be uncomfortably hot or cold, but fortunately, Western States Home Services can provide heating and cooling services to keep your home at a moderate temperature year around.

Types of HVAC Systems

An HVAC heating system can really be any type of system that provides heating or cooling or both. However, there are certain basic types of HVAC systems that are often used in residential and commercial buildings to heat and cool the rooms.

  • Hybrid heat pump system – In this system, an electric heat pump is used alongside a gas furnace. A heat pump is an air conditioner which can work in reverse to disperse heat. When temperatures are very low, the furnace will conduct the heating.
  • Heating and air conditioning split system – This is a split system where the outdoor unit contains the condenser and compressor and the indoor unit contains the evaporator coil and blower. The indoor unit is usually connected to a furnace or a heat pump, and ducts carry the air throughout the house.
  • Ductless mini-split heat pump – Ductless mini-split units are placed directly in the areas that require cooling and heating. They work with an existing heat pump and have their own fan coil, wires and refrigerant tubing.
  • Packaged heating and air condition system – These systems consist of a unit that houses the compressor, evaporator, and condenser all together, and many times these units are either on a roof or next to the foundation.

Types of Air Conditioning Systems

Air conditioning units are used to cool areas in buildings. These systems will either be a window unit or a central air conditioning system. A window unit will cool the room where it is located. A central air conditioning system will cool the entire home and can be paired either with a heat pump or a furnace.
