The Pros and Cons of Ducted Mini Split AC Systems

Mini Split AC

When installing an air conditioning system in Hawaii, a friend of mine had to deal with a lot of electrical requirements, so she decided to opt for a Ducted Mini Split AC. There are several pros and cons to choosing a mini split system, though. Here are some things to look for. Read on to learn more about the cost and energy efficiency of each option. Also, make sure you read the installation instructions carefully, as some units have special features.

Ductless mini-splits

A ductless mini split AC system is a high-efficiency HVAC system that uses a single air-flow duct instead of a complex network of ducted ducts. These units are great for small spaces and are ideal for apartments or mother-in-law suites. Although they cost more to install, ductless mini splits are worth the extra money. Ductless mini split AC systems are highly energy-efficient and can save you a lot of money over the lifetime of your HVAC system.

The BTU rating of a ductless mini split system is another important consideration. You need a system with the appropriate BTU capacity to properly cool a 400-square-foot room. Check out the chart provided by the manufacturer to determine what cooling capacity is required. The chart below outlines the BTU ratings for ductless mini split systems and their recommended size. The BTU rating of each type of unit will depend on its square footage and geographical location.

Ducted systems

Ducted systems for mini split AC are similar to unitary air conditioning units, but differ in some important ways. One of the main differences is that the two types have separate outdoor units and indoor units. While a ducted system has a central air handler, mini splits are more portable. They also have a smaller footprint and require fewer ducts, which is good news for homeowners. In addition, they are more cost-effective for small spaces.

There are many advantages to ducted systems. They offer several benefits, including centralized temperature control, individual zone adjustment, and flexibility of use. Ducted systems for mini split AC can be a smart choice for shared spaces, especially if everyone in the household has different temperature preferences. There is still debate between ducted and ductless AC systems, but there is a middle ground between the two. If you’re considering installing a ducted system in your home, make sure it’s right for your space.

Energy efficiency

The size and flexibility of a Mini Split AC system makes it ideal for zoning. In fact, many mini split systems have up to four indoor air handling units, each connected to its own outdoor unit. The number of indoor units depends on the cooling needs of the building, air sealing and insulation, and the thermostat settings in each room. With the thermostat setting, a Mini Split AC system only needs to condition the rooms that are actually occupied.

Another benefit of a Mini Split AC is that it is not required to have ducts. The absence of ductwork means that it does not incur the energy losses associated with central forced-air systems. Typically, ductwork accounts for up to 30% of the energy consumed by air conditioning systems. This is particularly significant in unconditioned spaces. As a result, Mini Split AC systems can save a significant amount of energy, while also costing less than the traditional central AC system.


The cost of a mini split AC system varies widely, depending on factors such as the cooling or heating capacity, number of indoor zones, warranty period, and brand name. A low-capacity single-zone unit can cost $700, while a high-capacity top-brand model may cost $2,000.

You can reduce energy bills by installing an energy-efficient mini split system in a house or apartment. Many energy companies offer rebates for energy-efficient home equipment, so it makes sense to look for a high SEER rating. This will reduce your energy bills, but make sure to check the unit’s warranty period before purchasing it. To get the best deal, compare prices from various manufacturers. If you can afford it upfront, a mini split AC will keep your energy costs down over time.


If you are considering installing a mini split AC system in your home, there are a few factors to consider before you do so. Though most mini-split models can be installed by a do-it-yourselfer, you may want to consider hiring a professional. While professional installation is not always necessary, it is a good idea to do so to avoid hassle and ensure the efficiency of your mini-split system. Keep in mind that most manufacturers will void their warranties if you do not use a licensed professional.

Ductless mini-split AC systems are typically installed outside the home, so an adequate power source is required. A dedicated 110, 220-, or 240-volt circuit is required. A HVAC technician will be able to hook up the in-room units to the appropriate circuit. If you do not have access to a dedicated 110-volt circuit, you can hire an electrician to prepare the necessary electrical wiring. The technician will also need to set up a box for the condenser unit, which should be located outside the home.
