What is a Ductless Mini Split Air Conditioning System?

A ductless mini split system, also known as a ductless air conditioner or heat pump, is a type of heating, ventilation, and air conditioning (HVAC) system that provides efficient cooling and heating to specific zones or rooms in your home without the need for ductwork. Unlike traditional central air systems that rely on a network of installed ducts to distribute air throughout the entire home, ductless mini-splits operate independently in each room or area they serve.

How Does a Ductless Mini Split A/C System Work?

Ductless mini split air conditioning systems consist of two main components: an outdoor condenser unit that creates the cold air and one or more indoor air handling units that push the cold air into the home. These units are connected by a conduit that houses refrigerant lines, power cables, and drainage pipes. The outdoor unit houses the compressor and condenser, while the indoor units are responsible for air distribution.

When the system is operating in cooling mode, the outdoor unit compresses the refrigerant, which then flows through the refrigerant lines to the indoor units. Inside each air handler, the refrigerant undergoes a heat exchange process, absorbing the warm air from the room and releasing cool air in return. In heating mode, the process is reversed, and the system extracts heat from the outside air to warm up the indoor space.

What is The Difference Between A Mini Split System vs. Central Air System?

The primary difference between a ductless mini-split and a central air system lies in their method of air distribution. Central air systems use a network of ducts built into your home to deliver conditioned air to all areas of the house, whereas mini splits deliver air directly into specific zones without the need for ductwork.

The biggest advantage of choosing a mini split system over central air is that a homeowner doesn’t have to have ductwork installed to make the system work. If you live in a home without ductwork this is potentially a major savings since the installation of ducts can be somewhat time-consuming and an added cost when installing an HVAC system in a home. Another advantage of these systems is that they allow for greater zoning control. Each indoor unit can be independently operated and set to different temperatures or turned off in rooms that are not being used, providing more personalized comfort and energy efficiency.

On the other hand, central air systems are generally more suitable for larger homes with many rooms as they offer a centralized control system and since the indoor units of a ductless system are typically only capable of heating or cooling the space that they are installed in homeowners would either need to install multiple units throughout their home or end of with heating/cooling ‘blindspots.’

If you are unsure of which HVAC system would be the most useful and efficient for your home contact our office. A Day & Night HVAC technician would be more than happy to provide an in-home consultation to help determine the best system for your Phoenix, AZ home.

Advantages of a Ductless Mini Split System

There are a number of reasons why someone might choose a ductless mini split system for their home.

  • Energy efficiency: Ductless mini splits are highly energy-efficient compared to central air systems. Since there are no ducts, there is no loss of conditioned air through leaks and gaps, which can account for a significant amount of wasted energy in central air systems.
  • Zoning flexibility: Mini splits provide the flexibility to cool or heat specific areas of the house independently, allowing homeowners to save energy by only conditioning occupied rooms.
  • Easy installation: Installing ductwork can be a cumbersome and expensive process. Ductless mini splits eliminate this need, making installation quicker, more straightforward, and less disruptive to the home.
  • Improved indoor air quality: Ducts in central air systems can accumulate dust, allergens, and mold, which then get circulated throughout the home. Ductless systems avoid this problem, promoting cleaner indoor air quality.
  • Quiet operation: Ductless mini splits are designed to operate quietly, enhancing comfort and minimizing noise disturbances.

Disadvantages of a Ductless Mini Split System

When trying to decide the best heating and cooling system for your home it is important to understand both the benefits and drawbacks of any system. Some of the things to consider when thinking about installing a ductless mini split system include:

  • Upfront cost: The initial investment for a ductless mini split system, including the outdoor unit and multiple indoor units, can be higher than that of a central air system.
  • Aesthetics: While indoor air handlers are compact and can be mounted on walls or ceilings, some homeowners may find them less visually appealing compared to the discrete nature of central air vents.
  • Limited capacity: Ductless mini splits are more suitable for cooling or heating individual rooms, smaller areas, or homes with an open concept layout. For larger homes or extensive cooling needs, a central air system is more likely to be the appropriate choice to make sure all areas of the home are adequately served.

How Much Area Will a Ductless Mini Split System Cool?

The cooling capacity of a ductless mini split system varies based on its size and model. Generally, a single indoor unit can effectively cool a room of around 300 to 500 square feet. Larger rooms or areas may require multiple indoor units or a larger capacity system. It is always best to speak with an experienced HVAC technician near you to help you determine the best system for your home’s cooling and heating needs.

How Much Does a Ductless Mini Split System Cost?

The cost of a ductless mini split system depends on a number of factors such as the brand, model, capacity, and the number of indoor units required. On average, a basic ductless mini split system can cost between $2,000 and $14,500 to install. This estimate varies greatly because each home is unique and the complexity of the installation must be considered. Typically it costs around $3000 per unit to install a ductless mini split system in a home.

How Are Ductless Mini Split Systems Installed?

The installation of a ductless mini split system is generally less invasive and time-consuming than that of central air systems. The first step is to have a qualified HVAC technician near you come and assess the layout of your home and determine the optimal locations for the outdoor condenser unit and indoor air handlers. Once that has been determined the indoor units are mounted on the walls, ceilings, or floors of your home, depending on the design and layout of each room. Small holes are drilled into the side of your home to pass the refrigerant lines and electrical cables between the indoor and outdoor units. Then the outdoor condenser unit is placed in a suitable location outside the home, and the refrigerant lines, power cables, and drainage pipes are connected between the indoor and outdoor units through the drilled holes. Once the ductless mini split system is installed, the system is thoroughly tested to ensure proper functionality and performance. The technician will also guide you on how to use and maintain your new ductless mini split system.
