As homeowners become more focused on efficiency and flexibility, it’s essential to offer solutions that align with their space, as well as their goals for comfort and energy efficiency. In this guide, we’ll break down the core advantages and considerations of mini-split and central AC systems.

Understanding the Basics of Mini-Splits vs Central AC Systems

What is a Mini-Split System?

Mini-split systems are typically ductless heating and cooling systems designed to provide flexible, zoned heating and cooling with high energy efficiency. These systems consist of an outdoor compressor and one or more indoor air handlers, connected by a refrigerant line. Unlike traditional HVAC systems, mini-splits do not require ductwork, simplifying installation and reducing energy loss.

For HVAC contractors, GREE mini-splits offer reliable performance with advanced inverter technology, which adjusts compressor speed to match the cooling or heating load. This capability optimizes energy use and delivers quiet, comfortable climate control for clients in both residential and commercial settings. GREE’s mini-split systems come in both single-zone and multi-zone configurations, meaning they can be installed to provide temperature control to a single area like a sunroom, new home addition, or a “too cold” or “too hot” spot that isn’t receiving adequate temperature control through single zone systems, but they can also heat and cool entire homes and commercial spaces through multi-zone systems.

What is a Central Air Conditioning System?

Central AC systems use a network of ducts to distribute cooled air from an outdoor compressor to each room in the home. For homes with existing ductwork, central AC systems offer consistent, whole-home temperature control and a discreet aesthetic. Typically central AC systems are either fully on or fully off, which is less efficient but does cool (and depending on the system, also heats) the entire home at the same time.

GREE central AC units deliver powerful performance with energy-efficient designs that help reduce operating costs while providing dependable, consistent comfort across the home. For contractors working on larger homes or spaces with ductwork in place, central AC offers a simple yet effective solution that meets whole-home climate needs.

Advantages and Disadvantages of Mini-Split Systems

Advantages of Mini-Splits Systems

Energy Efficiency: GREE mini-splits feature high SEER ratings and inverter technology that maximizes energy efficiency and reduces utility costs, ideal for clients who prioritize green living. Additionally, mini-splits don’t require ductwork, making them even more energy efficient, as leaky ductwork is responsible for the majority of heat loss with central AC systems.

• Lower Operational Costs: Increased energy efficiency means less energy consumption, ultimately resulting in lower monthly energy bills for your clients.
• Zoned Comfort: Mini-splits allow contractors to design multiple zones, giving clients the ability to control the temperature in each room or area independently, which optimizes comfort and further improves energy efficiency.
• Flexible Installation: Without the need for ducts, mini-splits are easier to install, especially in retrofits, additions, or buildings with unique layouts. For contractors, this flexibility can streamline project timelines and reduce labor costs.
• Environmental Impact: GREE’s mini-splits use R32 refrigerant, known for its lower global warming potential, allowing clients to meet eco-conscious goals. This environmentally friendly refrigerant, combined with increased energy efficiency, makes them an overall more environmentally friendly product.
• Rebates: Due to the strong energy efficiency provided by mini-split heat pumps, federal and state governments provide substantial rebates for these products, which helps to offset installation costs.

Disadvantages of Mini-Splits

• Higher Initial Cost in Some Circumstances: The upfront investment for mini-splits can be higher than central AC, especially in multi-zone setups, though they generally recouped through long-term energy savings. However, initial setup costs can vary very based on the market and the brand of equipment you’re installing. GREE mini-splits are renowned for combining high-performing equipment with a very reasonable price.
• Aesthetic Considerations: Indoor air handlers are visible in each room, and while GREE’s indoor air handlers are very aesthetically pleasing, they may not suit every client’s design preferences.

Advantages and Disadvantages of Central Air Conditioning

Advantages of Central AC

• Convenient Whole-Home Cooling: Central AC systems aim to provide temperature control throughout the home, making it possible to control a whole home’s temperature from 1 thermostat.
• Integration with Existing Ductwork: For homes with pre-existing duct systems, central AC is often a straightforward choice, integrating easily without the need for individual units in each room.
• Discrete Appearance: Central AC uses vents to distribute air, maintaining a clean look without visible units on walls or ceilings.

Disadvantages of Central AC

• Energy Loss: Ducts can develop leaks or inefficiencies over time, impacting energy usage and increasing operating costs for clients.
• Zoning Limitations: Traditional central AC lacks the flexibility for temperature control in specific rooms, which may result in uneven cooling, particularly in large homes. This is how you end up with rooms that are too hot or too cold, as different areas of the home may require specific temperature control due to increased sun exposure, or ductwork that doesn’t adequately cover the entire home.
• Complex Installation: Retrofitting central AC in older homes without ductwork can be costly and invasive, requiring careful planning and additional labor.
• Cooling Only: Traditional central AC systems often only provide cooling, meaning your clients will need a furnace or additional heat source to provide heating. That said, GREE’s central AC systems are heat pumps, which provide both heating and cooling to your clients.

The Best of Both Worlds: The GREE MultiPRO

For clients seeking the versatility of zoned control with the power of a whole-home AC system, the GREE MultiPRO is an ideal solution. MultiPRO offers the benefits of both mini-split and central AC systems, allowing HVAC contractors to deliver a comprehensive solution for any home.

Whole-Home Power and Efficiency

With the capability of handling up to 10 zones per outdoor unit, the MultiPRO is a robust multi-zone mini-split system designed to provide reliable, whole-home cooling and heating. Featuring inverter technology, the MultiPRO adjusts the energy output to match demand, making it a more efficient option than traditional central AC systems, especially in variable climates.

Flexible Zoning for Customized Comfort or Whole Home Heating & Cooling

MultiPRO’s multi-zone capability allows contractors to configure each area with independent temperature control, giving clients the flexibility to customize comfort in individual rooms. This is ideal for homes with diverse cooling needs, like upstairs rooms that receive more sunlight or high-traffic zones that demand more temperature control. However, the MultiPRO is also capable of functioning like a traditional AC system and can be configured to heat and cool the entire home consistently if that’s what your client desires.

Combining Mini-Split Efficiency with Central AC Coverage

With the MultiPRO, contractors can provide clients the flexibility to cool or heat the entire home or to create separate zones based on usage patterns and occupancy. This system offers the quiet operation and efficiency of a mini-split with the extensive coverage of a central AC system, making it an excellent choice for clients who need a combination of whole home heating and cooling, combined with flexibility.
