Why Should You Replace Your Old AC System with Ductless Mini Split? Advantages and Benefits Explored

If you’re considering replacing your old AC system, it’s worth considering the benefits of upgrading to a ductless mini-split system. Ductless mini splits offer a range of advantages that make them an attractive option for homeowners. This guide will explore why you should replace your old AC system with a ductless mini-split and how Harmon Mechanical Heating & Air can help you make the switch.

Energy Efficiency

Ductless mini-split systems are highly energy-efficient compared to traditional central AC systems. A ductless system lets you cool specific zones or rooms independently, allowing for personalized comfort and energy savings. By avoiding the energy losses associated with ductwork, ductless mini splits can be up to 30% more efficient, reducing energy bills and a smaller carbon footprint.

Improved Indoor Air Quality

Traditional AC systems with ductwork can accumulate dust, allergens, and other pollutants over time. Ductless mini splits eliminate this concern as they operate without ducts. With individual air handlers in each zone, there is no air circulation between rooms, minimizing the spread of contaminants. Additionally, ductless systems often include advanced air filters that capture smaller particles, ensuring cleaner and healthier indoor air.

Enhanced Comfort Control

Ductless mini splits provide precise temperature control for each zone or room. This level of customization allows family members to set their preferred temperatures in different areas of the home. With individual remote controls or smart thermostats, you can easily adjust the cooling settings according to personal preferences, promoting optimal comfort throughout your living spaces.

Easy Installation

Installing a ductless mini-split system is typically easier and less invasive than retrofitting ductwork or replacing a central AC system. Ductless systems consist of an outdoor unit and indoor air handlers connected by refrigerant lines, requiring only a small hole for the lines to pass through the wall. This makes ductless mini splits an excellent choice for homes without existing ductwork or for specific areas where extending ductwork is impractical.

Flexibility in Design

Ductless mini splits offer greater flexibility in interior design and room layout. With no ductwork, you have more freedom in furniture placement and room configuration. The sleek indoor units can be mounted on walls, suspended from ceilings, or installed flush in the ceiling.

Quiet Operation

Ductless mini-split systems are known for their quiet operation. Compared to traditional central AC systems that can be noisy due to the sound of air moving through ducts, ductless mini splits provide a quieter cooling experience. The indoor units are designed to operate silently, ensuring a peaceful and comfortable environment.

How To Switch From Your Old AC to A Mini-Split System

Switching from traditional AC to mini-split systems involves several steps and considerations. Here’s a general guide to help you understand the process:

  1. Determine installation requirements: Mini-split systems consist of an outdoor unit and one or more indoor units connected by refrigerant lines. You need to identify suitable locations for the indoor units, ensuring they are strategically placed to provide optimal cooling to the desired areas. Additionally, consider the available electrical capacity, as mini-split systems require dedicated electrical circuits.


  2. Hire a professional installer: Installing a mini-split system typically requires the expertise of a licensed HVAC professional. They will assess your home’s layout, electrical system, and cooling needs to determine the best installation approach. Professional installation ensures proper sizing, placement, and efficient operation of the system.


  3. Remove the existing AC system: The AC system must be properly disconnected and removed from your home. This involves disconnecting the refrigerant lines, electrical connections and removing the indoor and outdoor units.


  4. Install the mini-split system: The professional installer will mount the outdoor unit in a suitable location outside your home. They will then connect the indoor units, run refrigerant lines, and install electrical wiring as per manufacturer guidelines. Finally, they will ensure all connections are secure and conduct a thorough system test to confirm proper functionality.


The process may vary depending on your specific circumstances, so it’s important to consult with a professional HVAC installer who can guide you through the entire process and ensure a successful transition from a traditional AC system to a mini-split system.
