Best HVAC Books Reviews From Amazon: Updated 2026

What is HVAC?

HVAC is an acronym for Heating, Ventilating, and Air Conditioning. In an HVAC system, the environmental conditions within a home or office are controlled. This is the cooling and heating of the environment. Sometimes you will see HVAC/R used, and the “R” stands for refrigeration.

An HVAC system will also control the humidity level in the environment. It achieves this by controlling the distribution and movement of air inside a room. The HVAC system also maintains the air quality within the environment.

The 3 main types of the HVAC system are:

• A split and window air conditioning system
• A combined air conditioning and heating system
• A central air conditioning system

These systems do not all work in the same way. Some HVAC systems serve larger environments, while others are smaller and faster. HVAC systems vary in efficiency depending on the situation.

With a window air conditioning system, the fan blows air through the associated coils. This enables the separation of cold and heat. The heat is dissipated into the surrounding air, and the cold is introduced into the internal environment.

For larger applications, a split air conditioning system is best. This system will split the cold from the hot again. For the cold side, there is an expansion valve and a cold coil. These are usually located in an air handler or furnace. The handler blows cooled air across the coil, which is then distributed via air ducts throughout the environment.

With combined air conditioning and heating systems, the environment receives an “all-in-one” benefit. This is cooling and heating in a single package. You will find these on building rooftops or in dedicated mechanical rooms.

All of the cooling and heating components are in a single unit. A centrifugal blower or fan will distribute the cold or hot air throughout the environment. Residential buildings usually have a combined heating and cooling system.

For larger environments, there is usually a central air conditioning system. In a central AC system, the condensing unit contains a condenser coil, a compressor, and a cooling fan. They also use an evaporator coil located in an air handler or furnace.

The electrically powered compressor will pump refrigerant throughout the system, removing heat from the environment. The condensing unit coil dissipates the heat removed externally. Water vapor will condense on the coil, and a drain pan collects this. The air handler fan circulates the cooled air around the environment, maintaining a constant temperature.

The energy consumption of an HVAC system is dependent upon the amount of energy it requires and several other factors, including:

• Component efficiency
• The size of the system in the internal environment
• The climate
• The amount the system is used
• The fuel type to power the system

There are industry-standard ratings for HVAC systems, and the most popular ones are:

SEER (Seasonal Energy Efficiency Ratio) –This measures the efficiency of an AC or heat pump system. Higher SEER scores mean greater efficiency and energy saving.

AFUE (Annual Fuel Utilization Efficiency) – This is a rating of gas or oil furnaces and the amount of wasted energy. The AFUE rating is a percentage, and higher ratings indicate more efficient systems.

HSPF (Heating Seasonal Performance Factor) – This rating is about the efficiency of a heat pump in heating mode. Again, the higher the rating, the more efficient and cost-effective.

Wattage – the electrical rating of an HVAC system, measured in kilowatt-hours. The most important factor with a wattage rating is speed.
