HVAC Equipment

7th Edition

Featuring 91 tables and 89 figures – now available in Excel and Powerpoint!

The $20.7 billion US HVAC equipment industry differs between regions due to variances in climate, heating and cooling requirements, and type of buildings constructed. Competition from imported products has grown considerably as suppliers have relocated production to Mexico. Average HVAC equipment prices rose between 2.0% and 3.0% per year between 2008 and 2018. Price increases in 2018 were partly the result of import tariffs on steel and aluminum imposed by the Trump administration.

Heating and AC Equipment

This study analyzes the United States market for heating, ventilation, and air conditioning (HVAC) equipment. Products covered include:

  • air conditioning equipment, including unitary air conditioners, room air conditioners, packaged terminal air conditioners, chillers, and absorption chillers
  • heating equipment, including warm air furnaces, boilers, and room and zone heating equipment
  • heat pumps
  • whole building dehumidifiers and humidifiers

Products excluded from the scope of this report include:

  • portable HVAC equipment, including air conditioners, heaters, dehumidifiers, and humidifiers
  • ventilation equipment, including ductwork, radiators, and distribution pipes
  • parts and attachments

Demand for HVAC equipment is examined by product type, energy source, market, and region in US dollars at the manufacturers’ level. Unit demand estimates are also provided by product and market. Shipments are provided by product type in US dollars. Historical data for 2008, 2013, and 2018 and forecasts to 2023 are presented in current dollars (which are not adjusted to account for inflation).

Product Definitions:

Air Source Heat Pump

Function by transferring heat from one location to another. To warm the air in a buildings, the heat pumps pull heat from the outside air and transfer it into the home ductwork or individual air handlers. To cool the home, the process is reversed; the heat pump pulls heat from inside the structure and transfers it out of the home.


Either generate hot water to provide space heating or are used as a piece of industrial process equipment. However, some models provide both space heating and hot water generation. District heating boilers, including large-scale boilers and series of large-scale central boilers that generate hot water to provide heat for an industrial complex or a densely populated urban area, are included in this study. However, products associated with combined heat and power generation systems are not covered in this study, even though they are also radiant heat systems.

Central Air Conditioning

Air conditioning system that provides comfort cooling to an entire structure. Unitary air conditioners can also be described as central air conditioners.

Condensing Boiler

Boilers that have the ability to condense water vapor in the exhaust gas to recover additional heat that improves the efficiency of the unit compared to non-condensing boilers.

Heat Pump

As a type of heat transfer equipment, heat pumps function similarly to air conditioners but can also provide heat. They are also referred to as “reverse cycle heating”, “reverse cycle air conditioning”, “inverted air conditioners”, or “dual capacity air conditioners”. Heat pumps consist of the following major components: a compressor, a fan, condensing coils, evaporator coils, a metering valve, and a reversing valve. The system operates by using a compressor to pump the refrigerant to the coils..

Mini-Split Room Air Conditioner

Room air conditioners that have the condenser and compressor separate from the air handling components. Sometimes referred to as ductless mini-splits.

Packaged Unitary Air Conditioners

Consist of a central air conditioner that combines both condenser and air handling capabilities into a single unit.

Room Air Conditioner

Room air conditioners function similarly to unitary air conditioners and the cooling cycle of heat pumps, but they are designed to operate on a smaller scale. The condenser, compressor, and air handling components in a room air conditioner are located in the same cabinet, which is typically mounted in a window but can be installed in an opening in the wall. Portable units that operate as a free-standing unit with a duct that expels warm air through an exhaust vent in the wall, fireplace, window, or other venting location are also available.

Split Unitary Air Conditioners

The compressor and condenser are installed outside of the building, and an air handling unit is installed inside the building. Split systems are widely used in residential applications. Multi-split systems incorporate one central unit outside and a series of air handling units in several areas of a building. Multi-split systems are increasingly common in newer urban construction throughout the world.

Unitary Air Conditioner

Unitary is a term used to refer to the fact that all the components needed to cool, dehumidify, and move the air are included in one or more factory-made assemblies. These systems provide central cooling for an entire building. Although many of these systems incorporate a heating component within the same assembly, they differ from heat pumps in that the system does not reverse direction.

Warm Air Furnace

Warm air furnaces heat buildings by drawing air from rooms through ductwork and a filter into the furnace, where the air is heated using natural gas, electricity, or heating oil. The warm air then moves back into the rooms through the ductwork. Older warm air furnaces are known as gravity furnaces because the air is delivered by natural convection movement as warm air rises and cold air falls, but the majority of newer versions are known as forced air furnaces because the air is returned using a fan.
