What Are Central ACs?

A central air conditioner is a comparatively powerful cooling system. If you want something to cool larger home or office spaces then this is the perfect system designed to regulate the temperature. It has a network of ducts that operates to distribute cool air to multiple rooms from a single central unit. The system consists of an outdoor compressor unit and an indoor evaporator coil, which work together to cool and circulate air through the house. You have a thermostat that works as a control, enabling the central AC to provide uniform cooling, which is very essential for large home spaces and commercial buildings.
While they do provide you with consistent and seamless temperature control, it goes without saying that they require significant installation work. If you have ductwork in place then you can save up on some time and costs, otherwise, you need to construct one, shelling out a bit more money in the process.
What Are Mini Split ACs?
Mini Split Air Conditioners, are also known as ductless AC systems. They are quite an efficient alternative to central ACs, are easier to set up, and cost significantly less. You do not need any ducts for this AC, as they have an outdoor compressor unit and one or more indoor air handlers mounted on walls or ceilings.
Since the mini split system operates independently, they specifically cool a particular zone in your space. This allows you to set different temperatures in different rooms based on individual preferences. That is why these are a popular choice since they do not come with the additional cost of installation and are low energy-consuming due to the targeted cooling system, thereby ensuring there is no energy loss through ducts.
Key Features of Central AC Units and Mini Split AC Units
While both the central AC and the mini split system serve similar purposes it is essential to research some of the key features to make a better financial choice. Here is a breakdown of the key features of both types of ACs.
Central AC Units
Some key features of central air conditioning system are:
● Large Area Cooling - You can maintain a uniform temperature throughout the house as they can cool multiple rooms simultaneously. The system pulls the warm air from the house and cools it through a refrigeration cycle, redistributing the chilled air through ductwork.
● Ducted Air Distribution System - This ensures that the cool air is transported to different rooms, providing an even cooling. Since this system is complex and requires ductwork the installation also is quite daunting. Besides, you need to regularly check for filter replacement, duct cleaning, and refrigerant changes for efficiency and longevity.
● High Cooling Capacity - They are more varied in cooling capacity, which opens up various options in terms of sizes, that are measured by BTUs. This also makes them more powerful than mini-split systems and suitable for large residential or commercial spaces.
● Centralized Temperature Control - There is very little hassle regarding temperature changes as it is controlled via a single thermostat, which can be manual, programmable, or smart. To save more energy you can choose smart thermostats that enable remote control and automation.
● Integration with Heating Systems - Many models nowadays are combined with a furnace or heat pump to provide both heating and cooling from a single system (HVAC). This ensures that you have year-round climate control with a forced-air heating system.
● Air Filtration and Humidity Control - The built-in air filters are a blessing to those who live in areas with high dust, allergens, and pollutants. You may also opt for models with dehumidification features to maintain optimal indoor humidity levels.
● Noise Levels and Placement - Since the main cooling unit (condenser) is installed outside, indoor noise levels are reduced, with minimal noise emanating from air handlers or duct airflow.’
● Energy Efficiency and SEER Ratings - When choosing modern central AC systems look for those with high SEER (Seasonal Energy Efficiency Ratio) ratings as this can affect your energy bills. Most times, higher SEER ratings (above 16) indicate better efficiency and lower electricity costs.
Mini Split AC Units

Some key features of mini split system are:
● Ductless Design - Mini split ACs do not require ductwork, so you save a ton on the ductwork installation. They also eliminate energy loss associated with traditional duct systems, improving efficiency.
● Zoned Cooling - Mini split systems can cool specific zones and areas, which means that you can have multiple temperatures in different rooms. They also come with individual thermostats or remotes so that you can get personalized comfort settings.
● Flexible Installation Options - With multiple installation options like wall-mounted, ceiling-mounted, floor-mounted, or recessed, this AC gives you the flexibility to use your space effectively indoors. Meanwhile, outdoor units are compact and can be installed on the ground, wall brackets, or rooftops.
● Heating and Cooling Capabilities - Another good thing is that a Mini Split Air Conditioner comes with heat pump technology, doubling up as a heating system for winter.
● Noiseless Operation - The mini split AC’s compressor is located outside, making the units operate at low noise levels which go as low as s 19-25 dB.
● Smart and Remote-Control Features - Smart technology brings advancement to the appliance with remote controls, Wi-Fi connectivity, and smart home integration, which is compatible with Google Assistant, Alexa, and smartphone apps.
● Improved Air Quality - This AC also ensures dust, allergens, and pollutants-free environment, as it is equipped with multi-stage filtration systems. You can also opt for HEPA or ionizers for better indoor air quality.

Key Differences Between Central AC and Mini Split AC

Before proceeding it is always helpful to know some of the key differences between a central air conditioner and a Mini Split Air Conditioner.
1. Cooling Method
A central AC uses a single outdoor unit connected to a network of ducts that distribute cool air throughout the entire home, while a mini split AC operates with individual indoor units installed in specific rooms, which further allows specific areas or zones to cool without ducts.
2. Ductwork
Central ACs cool massive areas at once so they require ductwork to carry the cool air, making installation more complex and expensive, especially if you don’t already have an existing one. Mini split ACs on the other hand, are ductless and therefore most cost-effective, so you can cool specific zones without extra infrastructure.
3. Cost of Installation
Central ACs with their ductwork complexity incur higher installation costs. Mini split ACs have lower installation costs for single-room cooling, however, if you have multi-zone setups then it can become expensive.
4. Energy Efficiency
With extra maintenance Central ACs, be efficient, but remember the ducts can cause energy loss, increasing utility bills. Mini split ACs, contrarily, are more energy-efficient due to higher SEER ratings (20+) and no duct energy loss.
5. Temperature Control
Central ACs are controlled by a single thermostat, cooling the entire home uniformly, while Mini Split ACs cool particular zones, which means that each unit can be set to a different temperature for personalized comfort.
6. Aesthetics & Space Considerations
Central ACs are often out of sight as air is cooled through hidden ductwork, preserving the aesthetics, while Mini Split ACs need designated spaces like wall mounts, ceiling-mounts, or floor-stands making them visible and unappealing.
7. Heating Capability
Central ACs need a separate furnace or heat pump for heating the space while some Mini Split include a heat pump technology, reducing extra heating supplement costs.

1. Area Size & Layout - The first factor is to determine how much area you need to cool If you have a large home, with multiple rooms, opt for Central ACs as they provide uniform cooling. For a smaller home, an apartment, or a newly added room, a Mini Split AC works best as it is far more efficient and cost-effective due to targeted cooling options.
2. Ductwork Set-up - If you already have ductwork installed then setting up a Central AC system will be convenient, as it integrates seamlessly into the existing system. If not then you will have to install one which will be heavy on the pocket. To avoid a costly and time-consuming installation process, you can get a ductless Mini Split AC that is free from additional modifications.
3. Energy Efficiency - Energy consumption can be a major determining factor in the ultimate purchase when you consider long-term electricity costs. Since Mini Split ACs tend to have higher SEER ratings compared to Central AC systems, they become a more efficient option. There is always a chance that Central ACs may suffer from efficiency loss due to poorly insulated or leaking ducts.
4. Installation Cost - While the installation costs can vary significantly between the two systems, it all depends on your requirements. For instance, a Central AC typically has higher upfront costs, with the ductwork installation or repairs. This does not hold the same for Mini Split ACs, which are cheaper to install for single rooms. The expenses may increase if you need multiple indoor units for an entire home coverage.
5. Operating Cost - Since a Central AC cools a larger space, and at times unused rooms you can expect higher electricity bills. When it comes to Mini Split ACs, with their zoned cooling capability, the energy consumption can be controlled, reducing operating costs over time.
6. Maintenance Needs - A central AC can only work efficiently with regular maintenance like duct cleaning, filter replacements, and periodic servicing. Mini Split ACs are simpler to maintain as you basically have to clean the filters and do the refrigerant checks so that they can run smoothly.
