This makes it ideal for homes without existing HVAC ductwork. While both systems have their advantages, there are certain factors like mini split installation cost, mini split system cost, and mini split air conditioner installation that should be considered before making a decision. In this blog, you will gain a complete understanding of what a ducted HVAC system is and everything about ductless HVAC systems. You will also learn about the key differences between ducted and ductless HVAC systems and the essential factors to consider while choosing an HVAC system. Lastly, you will know about selecting the right HVAC system for your home.

Understanding Ducted HVAC Systems

A ducted HVAC system is a climate control solution that uses a central unit to distribute heated or cooled air through a network of air ducts in a building. The HVAC unit, which consists of a compressor, condenser, and air handler, is typically installed in the attic, basement, or an outdoor space. From there, the conditioned air is pushed through the HVAC ductwork and delivered to different rooms via vents. Ducted air conditioning is a preferred option for large homes, offices, and commercial spaces because it provides consistent temperature control throughout the entire building. Unlike a ductless HVAC system, which requires separate indoor units, a central AC system offers a more seamless and unobtrusive installation, making it an efficient long-term solution.

There are both advantages and disadvantages to ducted air conditioning systems. Some of the benefits include:

Even temperature distribution across all rooms.
The design is attractive because there aren't any indoor units to be seen.
Compatibility with smart climate control options.

However, there are also a few downsides:

Higher installation costs compared to ductless mini split installation.
Requires ample space for HVAC ductwork.
It can be less energy-efficient than a ductless heat pump in smaller homes.

Before choosing an HVAC system, it is important to compare factors like mini split AC installation, mini split cost, and mini split system cost to determine the best option for your home or business.
