Centralised AC vs Split AC for Home: Which is Better?

Choosing the right air conditioning system for your home is akin to selecting the perfect piece of furniture or decor that complements your space and enhances your everyday comfort. Picture a balmy summer evening, where the heat outside presses against your windows, eager to invade your sanctuary.

Inside, you envision a cool oasis where a gentle hum whispers promises of relief and tranquillity. It’s in moments like these that the choice between centralised AC vs split AC systems becomes pivotal, each offering distinct advantages tailored to varying household needs.

Listed below are tenets that form the foundation of your decision-making process: what is centralised AC, what is split AC, the differences between the two, and how can you save electricity for your air conditioner? Et cetera. Centralised AC systems stand tall as stalwart guardians of even cooling, their centralised command soothing multi-story residences and expansive homes alike with a symphony of ducts and vents. Meanwhile, split AC systems whisper energy efficiency and flexibility promises, cooling specific rooms or zones with targeted precision and minimal visual intrusion.

What is Centralised AC?

Centralised air conditioning systems work by using a central unit typically located outside or in a designated utility area of the home. This unit cools air and then distributes it through a network of ducts to various rooms and spaces. The process involves the central unit containing the compressor, condenser, and evaporator coil, which work together to cool and dehumidify the air before circulating it throughout the house.

What is Split AC?

Split air conditioning systems are composed of two main units: an outdoor unit containing the compressor and condenser and one or more indoor units for air distribution within specific rooms or zones. The indoor units are typically mounted on walls or ceilings and connected to the outdoor unit via refrigerant lines and electrical wiring.

Pros and Cons Comparison

Tabled below is a Centralised AC vs Split AC comparison regarding the elements to consider before your purchase:

How to Save Electricity Bill for Your Air Conditioner?

Energy efficiency plays a pivotal role in determining the long-term cost-effectiveness of an AC system. Centralised AC systems are typically evaluated based on their SEER (Seasonal Energy Efficiency Ratio) rating. This rating reflects how efficiently the system uses electricity to cool your home over the entire cooling season. Factors influencing SEER include the quality of duct insulation, system design, and the efficiency of components such as compressors and condensers. Higher SEER ratings indicate greater efficiency and potential savings on electricity bills.

In contrast, split AC systems excel in energy efficiency due to their zonal cooling capability (link to our article: Top 10 Tips to Improve Air Conditioner Efficiency and Save Energy). These systems use separate indoor units to cool specific areas or rooms as needed, avoiding the energy losses associated with ductwork. By cooling only occupied spaces, split AC systems reduce overall energy consumption, translating into lower electricity bills over time. This targeted cooling approach is particularly beneficial in homes where certain areas require cooling while others do not, optimising energy usage without compromising comfort.

Installation and Maintenance

Installing a centralised AC system involves planning and designing ductwork throughout the home, which can be complex and costly. On the other hand, split AC systems require mounting the indoor units and connecting them to the outdoor unit via refrigerant lines, making them simpler and less invasive to install. Maintenance for both systems involves regular upkeep, with centralised AC requiring duct cleaning and system checks, while split AC focuses on cleaning filters and checking individual units.

Considerations Before Purchase

Centralised AC systems generally involve higher upfront costs due to ductwork installation and equipment expenses. In contrast, split AC systems are more affordable initially, making them a practical choice for budget-conscious homeowners. Over time, operational costs may vary, with centralised AC potentially costing more due to energy loss through ducts and higher maintenance needs, while split AC systems benefit from targeted cooling and lower maintenance requirements.

1. Centralised AC Systems

Centralised AC systems provide consistent temperature control throughout larger homes or multi-story residences. These systems are designed to cool multiple rooms or entire floors evenly, ensuring uniform comfort across expansive living spaces. This capability is particularly beneficial in homes where maintaining a consistent indoor climate throughout various rooms is essential for comfort and productivity.

In addition to temperature consistency, centralised AC systems can integrate advanced air filtration systems. This feature enhances indoor air quality by capturing dust, allergens, and pollutants throughout the entire home. Improved air quality not only promotes a healthier living environment but also contributes to overall comfort and well-being.

2. Split AC Systems

Split AC systems offer flexibility and efficiency and are ideal for smaller homes, apartments, or specific rooms requiring individual climate control. These systems allow you to cool only the rooms or zones that are in use, optimising energy usage and reducing operational costs. This zonal cooling capability is advantageous in spaces where cooling needs vary throughout the day or where certain areas require cooler temperatures while others remain unoccupied.

Moreover, split AC systems are relatively easy to install compared to centralised systems, making them a practical choice for residences where space constraints or architectural considerations limit the installation of ductwork. The ability to install units discreetly on walls or ceilings minimises visual impact and preserves interior aesthetics, which is particularly important in smaller living spaces.

3. Choosing the Right System

When selecting between centralised and split AC systems, consider the specific requirements of your home and lifestyle. Larger homes with extensive cooling needs and a preference for consistent indoor temperatures may benefit most from centralised AC systems. These systems provide comprehensive cooling solutions with integrated air quality enhancements, which are ideal for households prioritising uniform comfort and air purity.

Conversely, smaller homes, apartments, or rooms with varying cooling demands can maximise efficiency and cost-effectiveness with split AC systems. These systems offer targeted cooling solutions tailored to specific areas, reducing energy consumption and operational costs over time. The flexibility in installation and maintenance requirements further enhances the appeal of split AC systems for residences seeking customisable climate control solutions without compromising on comfort or aesthetics.

Conclusion

Understanding the suitability of centralised and split AC systems for different home types is essential in making an informed decision that aligns with your cooling preferences and budgetary considerations. Whether you prioritise uniform temperature control across large spaces or targeted cooling efficiency in smaller areas, evaluating these factors will help you select the AC system best suited to meet your household’s unique needs and enhance overall comfort and energy efficiency.
