What Are the Types of HVAC Systems
February 24, 2025

HVAC systems are intended to keep the home warm and cool according to the weather conditions so that people living inside the home feel comfortable.

There are two main types of HVAC systems: Ducted HVAC Systems and Ductless HVAC Systems. In Ducted HVAC systems, air passes through multiple ducts to cool or heat the space. In a Ductless HVAC system, as the name suggests, there is an absence of ducts, so the air is delivered through alternative methods. Understanding the types of HVAC systems helps in selecting the right solution for your needs.

Types of Ducted HVAC System
When exploring the types of HVAC systems, it’s essential to consider factors like efficiency, cost, and the specific requirements of your space.
Ducted HVAC systems use ducts to distribute the air throughout the home, they are mostly used in residential and commercial buildings. The ducted HVAC system consists of an outdoor unit, an indoor unit, and ducts that carry the air. For more clarity, if any building uses vents to pass hot and cool air have a ducted HVAC system.
Split System:
A Split system is also known as a forced air system, in this system some components are located inside the home while others are located outside. It has two separate components one for heating and one for cooling, and a thermostat is used to control the temperature. In a split system heating and cooling systems are both connected to building ductwork through several tubes.
Hybrid Split System:
The Hybrid Split System is the same as the split system the difference is split system depends only on gas to generate heat while the hybrid split system uses gas as well as electricity. It is also known as a dual-fuel system. Electric heating is less powerful than gas-enabled heating, but it reduces energy consumption.
Packaged Heating and Cooling:
The packaged heating and cooling systems are smaller in size which makes them perfectly suited for the smaller sized spaces. As compared to the split system this system costs less, and this is a single unit, so it is easy to maintain.
Zoned System:
Zoned systems allow for control of the temperature in separate rooms or individual parts of the building. Zoned HVAC systems use dampers in the ducts that block or give direction to air to the specific zones. Each zone has its thermostat to customize the temperature settings according to your convenience.
Types of Ductless HVAC System
As the name suggests ductless HVAC systems do not require ducts to heat or cool, these systems are commonly used on temporary working sites.
Ductless Mini Split:
Ductless mini-split systems are installed in a separate room usually in a large office building, hotel rooms, and residential buildings. This system mainly consists of an indoor air handling unit, heat pump, outdoor compressor and condenser, power cable, and a thermostat.
A ductless mini-split system is expensive to install but it helps to reduce energy consumption. In cold environments, the heating components work less effectively in such a case you need to add an extra heating system.
Hydronic System
In all HVAC systems, we use air to radiate heat but in hydronic systems rather than air water is used to radiate heat. These systems typically consist of boilers, pipes, radiators, and radiant floor systems. Boilers are used to heat the water then it is distributed with the help of multiple pipes throughout the building. Hydronic heating systems are compatible with different fuels including gas and electricity.
Portable Spot Cooler:
Portable spot coolers are air conditioning units used to cool large rooms or outdoor areas. They work by pulling in ambient air, cooling it using a refrigerant-cooled coil, and passing it back into the area to remove humidity. Portable spot coolers are best suited in cooling areas where traditional AC systems can’t reach. These systems are easily movable, but an exhaust setup is needed to prevent warm air from re-entering.
Portable Heat Pump:
Portable Heat Pumps and spot coolers are similar in size and function the difference is it has both heating and cooling capabilities and offer additional heating options for cold environments. In heating mode, a heat pump takes in outside air, passes it over the condenser coil, and then distributes warm air throughout the room.
Selecting the right HVAC system requires considering factors like space size, climate, and energy efficiency. Ducted systems offer consistent control, while ductless options provide flexibility and cost savings. By understanding the different system types, you can make a well-informed decision to ensure year-round comfort and optimal energy performance for your home or business.
What is the best HVAC system for my home?
When choosing an HVAC system, you should consider factors such as energy efficiency, the size of your home, and climate conditions.
What is the difference between HVAC and AC?
HVAC controls the temperature, air quality, and humidity while AC only controls cooling, AC is part of the HVAC system.
