What is a Ducted Air Conditioning System?

A ducted air conditioning system is a central cooling and heating solution that uses a network of ducts to distribute conditioned air throughout a home or building. The central AC unit, usually installed on the roof, balcony, or utility area, supplies cool air into ducts that run through ceilings, floors, or walls. The air is delivered into each room through diffusers or vents. Ducted ACs are ideal when you want uniform cooling for an entire space without visible indoor units.

What are the Types of Ducted Air Conditioning Systems?

Ducted air conditioning systems are widely chosen for cooling expansive areas. There are mainly two types of ducted air conditioning systems. They are:

Central Ducted AC System

A fully centralised unit that cools the entire home. It includes an outdoor compressor and an indoor air handler connected to a wide duct network.

Ducted Split AC System

A split AC with a concealed indoor unit placed in the ceiling cavity. It distributes cool air through ducts to multiple rooms.

Compact Ducted AC Units

Used in apartments with limited ceiling space. These units provide efficient cooling while using smaller duct paths.

Mini Split AC

Mini splits do not require ducts. They cool individual rooms and are often used where ducted installation is not feasible.

How Does a Ducted Air Conditioning System Work?

A ducted air conditioning system, commonly known as a central air conditioner, distributes cooled air from a central unit through a network of ducts and vents to the various rooms in a building. The central air conditioner is typically located in a dedicated space, such as the attic, roof, basement, or mechanical room. 

• The thermostat senses room temperature and signals the AC to start.
• Warm indoor air is drawn into return air grilles.
• This air passes through a filter and moves over the cold evaporator coils.
• The refrigerant absorbs heat and cools the air.
• The cooled air is pushed through ducts and delivered to each room.
• Air circulates back through return ducts, completing the cycle.

A Ductable AC for the home is popular for better interior aesthetics. In commercial buildings, a high cooling capacity is needed. Versatility is a feature of ducted systems; they may incorporate UV lights to destroy bacteria and enhance indoor air quality, provide fresh air, enable heat recovery, and improve filtration.

Main Components of a Ducted AC System

Understanding the main components of a ducted AC system helps you identify performance issues and maintain efficient cooling. Key parts like the indoor unit, outdoor unit, ducts, vents, and thermostat work together to deliver uniform airflow throughout your home.

• Outdoor compressor and condenser
• Indoor air handler with evaporator coil
• Supply and return ducts
• Zone dampers for temperature control
• Diffusers and grilles
• Thermostat and controller
• Air filters
• Optional UV lights or heat recovery units for air quality

What are the Benefits of a Ducted Air Conditioning System?

Ducted air conditioning systems are renowned for delivering steady comfort, visual appeal, and energy efficiency. But these are not the only benefits that a ducted air conditioning system provides. Some additional Benefits include:

What are the Drawbacks of a Ducted Air Conditioning System?

Despite their advantages, ducted air conditioning systems have drawbacks you should be aware of. They are:

Higher Installation Costs

Ducted air conditioning systems are often more expensive than split-system air conditioners. The AC and duct installation cost range can vary between ₹25,000 per ton to over ₹1,00,000 per unit.

Requires Adequate Ceiling Space

Ducted air conditioning systems require space for ductwork, which can be a challenge in some homes. The AC ducting installation process can be more complex and expensive in existing homes.

Ongoing Maintenance and Repairs

Ducted air conditioning systems require regular maintenance to operate efficiently. The cost of maintenance and repairs can be higher than split system air conditioners.

Possibility of Airflow Restrictions

Ductwork can restrict natural airflow, creating stagnant areas and contributing to allergies and diseases. In addition, the ducts can become a breeding ground for insects and mould. This can be a problem in older houses with deteriorated fibreglass lining.

How to Choose the Right Ducted Air Conditioning System?

Choosing the right ducted air conditioning system is easy. You must follow these steps:

Step 1. Choose the Right Capacity

The ducted air conditioning system should be sized to the area you want to cool. A system that is too small will not cool the area effectively, while a system that is too large will save energy and money.

Step 2. Consider the Type of Ductwork

Ductwork is an essential component of a ducted air conditioning system. There are several types of ductwork, including flexible, rigid, fibreglass-lined, fiberboard, fire-rated, kitchen exhaust, PVC, and pre-insulated duct. Choosing the correct kind of ductwork compatible with your home’s structure and the air conditioning unit is essential. 

Step 3. Choose the Right Air Conditioning Unit

There are different types of air conditioning available in the market, such as central, ductless mini-split, portable, floor-mounted, window, smart, geothermal, hybrid, or dual units.  It is essential to choose the right unit for your home’s cooling needs.

Step 4. Select the Suitable Diffusers and Grilles

These affect airflow and sound levels. Popular choices include round diffusers, linear grills, and square diffusers.

Step 5. Consider the Energy Efficiency

When choosing a ducted air conditioning system, it is critical to consider energy efficiency. Reduced energy costs are achievable with an energy-efficient system.

Step 6. Choose a Reputable Installer

Choosing a reputable installer ensures your ducted air conditioning system is installed correctly. A reputable installer can also provide you with valuable advice on choosing the right system for your home.

What are the Factors Affecting the Cost of a Ducted Air Conditioning System?

The cost of getting a ducted air conditioning system varies depending on several factors. Some of the factors that can influence the cost are:

• Size of the Home: Larger areas require longer duct networks and higher-tonnage units, increasing costs.
• Number of Zones: More zones require additional dampers and controllers.
• Type of Ducted System: Reverse-cycle and multi-zone systems are more expensive than cooling-only units.
