Ductless Mini Split vs Central Air: Cost Comparison

Thinking of installing central AC or mini splits for your entire home? You might want to consider our input to help you decide on the right type of air conditioner to have in your space. 

Choosing the right cooling system for your home can be daunting, especially when comparing ductless mini-split systems to a central AC system. Both options provide effective cooling, but their costs, efficiency, and installation processes differ significantly. Let’s dive into the details to help you make an informed decision.

Understanding Ductless Mini Split Systems

A ductless system is popular for homes without existing ductwork or those needing targeted cooling. They consist of indoor and outdoor units, making them versatile and convenient. With mini splits, you can install wall-mounted or floor-mounted units to suit your aesthetic preferences and cooling needs.

Advantages of ductless mini split air conditioning systems include:

• Energy efficiency: By cooling only the rooms you use, these air conditioner systems save energy and lower your utility bills.
• No ductwork installation: These indoor units eliminate the need for costly ductwork, ideal for homes lacking air ducts.
• Individual temperature control: You can set different temperatures for various rooms, enhancing comfort.

What Is a Central Air System?

A central air system uses ducts to distribute cool air throughout your home. Typically, a central air unit consists of an outdoor compressor connected to an indoor unit. This system cools the entire home uniformly, ensuring a constant temperature throughout the living space.

Advantages of a central air system include:

• Whole-home cooling: Perfect for larger homes, cooling every room evenly.
• Distribute cool air efficiently: Ideal for homes with existing ductwork.
• Improved air quality: With air filters, central systems help maintain cleaner air inside.

Is it Cheaper to Run a Mini-split or Central AC?

When comparing mini split vs central air, costs depend on installation, operation, and maintenance.

Installation Costs

Installing ductless mini splits typically costs Php116,000 to Php450,000, depending on the number of indoor units and the complexity of the installation. You’ll need only a small hole for the connection, minimizing structural changes.

On the other hand, a central air conditioner can cost between Php170,000 and Php400,000, but adding ductwork installation for homes without it may significantly increase costs.

Operating Costs

When it comes to operating costs, mini splits are more energy efficient, as they avoid energy losses common in duct systems. This translates to lower energy bills. A central air conditioner may consume more energy, especially in homes with older or leaky ducts.

Maintenance Costs

Mini-splits require regular cleaning of filters and occasional servicing of the outdoor compressor. Meanwhile, central air conditioner systems demand duct cleaning and more extensive maintenance of the air conditioning system.

Energy Efficiency: Which System Saves Money?

If you want to save money on energy bills, ductless mini splits have the upper hand. They avoid the energy losses associated with ducts and provide better temperature control, reducing unnecessary cooling. Meanwhile, central AC systems can be less efficient, especially if the air ducts are poorly insulated.

Key Considerations: Mini Split vs Central Air Conditioning System

If you’re keen on having one indoor unit, here are some considerations to keep in mind: 

Home Size and Layout

For an entire house, a central air conditioning system may be more practical due to its ability to cool multiple rooms simultaneously. This central air conditioning system is ideal for larger homes or spaces where even temperature distribution is a priority. On the other hand, mini-split systems excel in providing targeted cooling for specific rooms, making them perfect for smaller homes or areas with unique cooling needs.

Existing Infrastructure

Homes with existing ducts are better suited for central air, as the infrastructure allows for seamless integration and lower installation costs. However, ductless systems are a smart choice for older homes, new additions, or spaces where adding ducts would be prohibitively expensive or disruptive. These mini split systems provide flexibility and efficiency without the need for extensive renovations than a central air system. 

Energy Needs

For those prioritizing energy efficiency, ductless central air conditioning units are more ideal than mini split systems because they avoid energy losses since you don’t have to install ductwork. They allow for precise temperature control, ensuring you cool only the spaces you use, which can significantly reduce energy consumption. 

Conversely, central air conditioner systems and wall units may consume more energy, particularly if the ducts are poorly insulated or outdated. They can also sometimes lose energy if one system is not installed properly. 

Choose the Best HVAC System

Choosing between ductless units and a central air system comes down to your home’s structure, cooling requirements, and budget. While mini splits offer flexibility and energy savings, central systems are a reliable choice for whole-home cooling. You can select the best HVAC system to keep your home comfortable year-round by considering your unique needs.
