What are the 4 main types of HVAC systems?

For many homeowners, the concept seems difficult to understand given the wide range of domestic cooling and heating systems. However, as long as you know the purpose and function of the various types, you’ll find that the fundamentals of HVAC (heating, ventilation, and air conditioning systems) are rather simple to grasp.

HVAC systems generally fall into four main groups with varying features and dimensions. More advanced choices are available in recent models, including variable fan speeds and numerous heating and cooling phases. Let’s talk about the four main types of HVAC systems that are available on the market today.

1. Heating And Cooling Split Systems

As implied by the system’s name, there are two main units: one for cooling and one for heating. Split HVAC systems, which combine heating and cooling, are thought to be the type that is most common.  Since they are extremely adaptable and do not have any particular requirements or environmental conditions, they are the most widely utilized. 

Your air is cooled by an outside unit that uses coils, compressors, and a refrigerant. Next is the heater, typically kept in the basement or other common home space for storage. The heated air is transported around your house using a fan or an evaporator, and it heats your home using gas.

2. Duct Free (Mini Split) Systems

Every room has a separate unit on this HVAC system, providing you with total control. These devices are frequently connected to an outside compressor and installed on the home’s interior walls. For every outside unit, some homeowners may have up to four internal handling units (also known as zones or rooms). Since every area is heated, another major advantage of modern HVAC systems is their energy efficiency. It prevents energy from being wasted in any unused spaces.

Installing these systems might be a good idea to reduce energy costs or downsize your home. Keep in mind that mini-split systems frequently require thorough and routine cleaning/maintenance to prevent expensive repairs and replacements.

3. Hybrid Split Systems

Hybrid split systems, which differ somewhat from heating and cooling split systems, are another HVAC system. The compressor and condenser are located outside the unit, whereas the blower and evaporator coil are within. Its interior unit is often linked to a furnace or heat pump.

Since hybrid split system models use less energy than their electric hybrid counterparts, they are becoming increasingly popular. The key difference is the capacity to quickly and effectively convert from gas to electric power while maintaining a reasonable level of quietness. Additionally, the system uses standard ductwork, thermostats, and all other advantages of a split design.

4. Packaged Heating And Air Systems

A heating and air unit that is kept indoors is part of a packaged heating and air system. This HVAC system is often located in the attic or another storage space on the top floor. It may be used to both chill and heat your home. The modest size of a packaged heating and air system makes it ideal for smaller homes and spaces. It also requires little maintenance and is quite effective.

Since its heating system is less strong than other options, packaged heating and air systems are frequently employed in warmer climates. Although some people can mix gas and electric sources, electricity still produces most of the heat.
