Types of HVAC Systems and Their Benefits


There are multiple different types of HVAC systems to choose from for your home or business, each with its own set of optimal usages and unique benefits. If you are considering a new HVAC system installation, take some time to familiarize yourself with all the options below so you can make an informed decision.

HVAC Outside Fan

HVAC systems include four main types: split systems, hybrid systems, duct-free systems, and packaged heating and air systems. Chancey & Reynolds’ NATE-certified technicians are experienced in the installation and maintenance of each of these categories of HVAC systems, and our experts have gathered the following information to help you make the best choice for your heating, cooling, and indoor air quality needs.

Heating and Cooling Split Systems

Split systems are the most common type of heating and cooling system, most widely used because they are the most generally applicable without specific needs or environmental factors. As the name suggests, the HVAC system is split between two central units, one for heating and one for cooling. These systems are significant because they contain easily recognizable indoor and outdoor units. Heating and cooling split systems have a cooling system outside, which uses refrigerant, compressors and coils to cool air, and a fan to blow out hot air. These are usually the large AC units outside the home, which run primarily during spring and summer in warmer climates like Tennessee.

The heating and cooling split systems also have a heater (typically located in a basement or other storage space) that uses gas to heat the house. Either a fan or an evaporator circulates the heat throughout the indoor space. Split HVAC systems use a traditional thermostat to manage the temperature and are able to keep most houses at your desired temperature. Most split units are also packaged with purifiers and humidifiers to keep you comfortable no matter the weather.

Hybrid Split System

Hybrid split systems are similar to the split systems detailed above–but with a few key differentiators. This type of hybrid HVAC system is rising in popularity due to its ability to mitigate energy costs through its electric hybrid heating system. The ability to switch between gas power (faster, more complete) to electric (more efficient, quieter) allows the user to decide how they want to heat their home. Hybrid split systems are helpful in mild climates where they take advantage of temperate weather where electric power will suffice. This system uses traditional ducts and thermostats while providing all the benefits of a split system with the added option to conserve energy and save on utility bills.


A ductless or mini-split system is a unique system with significant up-front costs but substantial benefits for specific needs and applications. These HVAC units are individual to each room, providing greater independent control. Ductless HVAC units are mounted on walls indoors and usually attached to an outdoor compressor. This installation process is expensive and visually apparent. They are perfect for new additions to homes, such as garages, additions, or additional buildings, because it is easier to install, and allows independent control of the unit. These types of HVAC units are also beneficial for service businesses such as hotels or venues, allowing tenants to control individual temperatures and conditions. Energy conservation is an added benefit of ductless systems. Since individual rooms are being heated, a ductless HVAC system keeps exterior or unused rooms from wasting energy.

Packaged Heating and Air

Packaged heating and air units are the most unique category of HVAC systems. It is a contained heating and air unit stored within the house or business. It is usually kept in an attic or top-floor storage space and serves to both cool and heat a house. Its compact size makes it useful for smaller rooms or houses and allows it to be placed within the home if an exterior is not an option. These types of HVAC systems are also able to be very efficient and easily maintained. They are generally used in warmer climates since the heating system is not as powerful as other options. The heat is generally electrically generated, but other forms can combine gas and electric abilities.
