When to Go Ducted Vs a Split Aircon System

Deciding between a ducted air conditioning system and a split system can be a challenging task. Both options have their own pros and cons and are suitable for different situations. Location, energy efficiency, cost, and the size of your home are crucial factors in making this decision.

A ducted system is typically ideal for cooling an entire house. If you have a large family or want the same temperature throughout your home, a ducted aircon may be suitable for you. Installing this system can be slightly costly and is best done during the house construction phase for aesthetic purposes.

On the other hand, a split air conditioning system is cost-effective and suitable for cooling a single room or a small space. It's easier to install than a ducted system, providing a convenient alternative for smaller homes or individual rooms. However, you might need more than one split system to adequately cool an entire home, which may affect energy efficiency.

Thus, it's essential to consider your unique requirements before settling on a system. For more detailed advice and maintenance services on both systems, consider seeking the help of experts like professional aircon servicing with Advanced Clean Air.

Defining Ducted Air Conditioning

A ducted air conditioning system is a versatile solution that works by circulating cool or warm air through insulated pipes, also known as ducts. These systems offer the advantage of whole-home cooling or heating in one package.

With a centralized control unit, you can manage temperatures in different rooms according to your preferences. The control system allows you to create zones ensuring optimal comfort and energy efficiency using a single system.

Ducted air conditioners are typically hidden, meaning they are not visibly intrusive. Furthermore, this type of system works almost silently, enhancing your living comfort without disruptive noise.

  • Ease of control: With a single control unit, regulating temperatures across rooms becomes easy and seamless.
  • Silent operation: The quiet operation of ducted systems offers homely peace without interference from any disturbing sounds.
  • Optimal coverage: A singular approach to cooling or heating is provided throughout the home.

Considering the steady adoption rate of split air conditioning systems globally, particularly rising at about 5-7% per annum in Asia-Pacific regions, it becomes increasingly important to understand the pros and cons of both split and ducted systems.

In your decision-making process, remember that factors such as the size and layout of your home play a crucial role. For example, larger homes or those designed with multiple rooms might better benefit from ducted systems than smaller ones.

Split System Air Conditioning Explained

Unlike ducted systems, split air conditioning systems are not connected through a network of ducts. Going for this type of system often gives you more flexibility, as you can cool or heat different areas of your home to varying degrees.

Your choice between a ducted and split aircon unit should largely depend on your preferred level of noise. 

Consider this fact: 

Noise Levels: Ducted air conditioning systems typically operate at around 60 decibels (dB), whereas split aircon units operate at around 40 dB for the indoor unit and 50-60 dB for the outdoor unit.

  1. Individual Room Control: One of the benefits is the independence you get with managing temperatures in various rooms. This is why a split system can be a better choice if individual room thermal control appeals to you.
  2. Cost and Installation: In general, installation costs as well as operation costs tend to be lower for split systems than for central systems. If budget is a priority, this point helps make split systems an attractive option.

If the noise level or cost concerns you, it may be time to consider replacing your current system with a quieter, more energy-efficient split system.

Advantages of Ducted Systems

Your first advantage when choosing ducted systems is consistency. Ambient temperature remains the same throughout your space, eliminating hot or cold spots.

This feature allows even cooling in large spaces. Thus, making ducted systems ideal for commercial properties and larger homes.

Efficient Energy Use

Ducted systems boast an impressive Seasonal Energy Efficiency Ratio (SEER), falling between 13 to 21. This ranges close to split systems which also reflect SEERs from 13 through to 23 or more. 

Despite split systems occasionally presenting superior efficiency rates, especially for inverter models, it's clear that the energy efficiency of both are competitive.

Property Value Increase

An often overlooked benefit; installing a ducted system may potentially boost your property value. These sophisticated air conditioning units are perceived as superior due to their comprehensive nature, reliable performance and sleek finish.

All-in-one Solution

Ducted systems provide an all-in-one heating and cooling solution. Unlike split units, which commonly only offer cooling capabilities, ducted units seamlessly transition between modes depending on your comfort requirements. Your level of convenience is unmatched with a ducted system.

Visual Appeal

Mainly hidden away within your property's structure, ducted aircon systems routinely receive praise for their minimalistic visual impact. No bulky external components on display means you maintain a clean, uncluttered aesthetics in your home or business premises.

Benefits of Split System

Efficiency is a hallmark of split aircon systems. When cooling a smaller area, split systems often outshine their ducted counterparts. Unlike ducted systems, they focus their functionality on specific zones, thereby ensuring optimal climate control and eliminating waste of energy.

Installation flexibility is another key feature. With no complex ductwork involved, you may place your split system almost anywhere in your home. This translates into customization and easier deployment in structures where invasive installations aren't favored.

Maintenance of these units is typically simpler compared to ducted systems. Cleaning filters or servicing the outdoor or indoor units don't require specialized skills; most homeowners find this type of maintenance manageable.

Noise level is another factor to consider when choosing an AC system. Split system air conditioners operate quietly, this advantage can be significant if tranquility is a valuable aspect of your home environment.

Cost Comparison: Ducted vs Split

Setting up a productive cooling system is essential and involves financial investment. Cost considerations, therefore, play a crucial role when selecting between ducted and split aircon systems.

Initial Installation Costs

Split aircon systems generally have lower installation costs than ducted systems. This is because ducted systems require more labor-intensive processes such as installing new ductwork in your home.

Energy Efficiency Analysis

In terms of energy efficiency, ducted systems often lag behind. Split aircon systems are known for their energy-efficient design leading to less power consumption and lower energy bills over time.

Maintenance Expenses

Maintenance costs add up over the lifespan of your system. For split aircon systems, these maintenance expenses are relatively low as compared to those of ducted units.

Market Share Trends

A recent market analysis shows that split aircon systems hold the majority of the global market share. They account for upwards of 75% as opposed to ducted systems. This dominance reflects the preference based on cost-effective operation and installation factors commonly associated with split systems.

Ducted vs Split: Efficiency

Examining the efficiency of both ducted and split systems is critical in your decision-making process. This comparison works best if you consider both the cost of installation and the method's long-term efficiency.

For instance, ducted aircon systems offer a seamless, aesthetically pleasing option because they blend in with your property's design. They provide excellent uniform cooling or heating to an entire house.
