Our mini split ac vs. central air doesn’t outrightly condemn one option in favor of another. However, we highlight the important aspects of each one and let you make your decisions.

Pros of Ductless Mini Splits

Efficiency

One of the biggest reasons homeowners have ignored the ductless mini splits installation cost is its efficiency. The system is relatively new and leverages improved technology which guarantees better energy use.
The ductless mini-split comes with an inverter technology that converts high-voltage electricity into DC voltage. The conversion ensures that it can run on little energy.
Most ductless mini-split systems also have a SEER rating of over 30 on the cooling side with high heating efficiency.
The mini-split units also use variable-speed compressors to run as much or as little as needed to keep the indoor temperature balanced.

Built-In Zoning

Mini-splits are commonly installed in individual spaces like patios, living spaces, garages, sunrooms, finished basements, attics, etc. This means that homeowners can enjoy improved flexibility over the comfort level in each home area. For example, a homeowner may decide to reduce the cooling temperature in the living room while cranking up the ac unit in the bedroom. Each of the units is independent of the other.

Ductless

Most mini-split ac units are ductless. Ductless systems require less work and cost less to install. You can easily circumvent the extra cost required to install a working duct system, thus saving time and money.

Flexibility

Homes and businesses choose the ductless mini splits system because of its high level of flexibility. One room can be independent of another, allowing users to tailor their cooling needs to their specific preferences.

Cons of Ductless Mini Splits

Filtration

Air filters are great for maintaining indoor air quality. Although ductless mini-split comes equipped with air filters, they aren’t as powerful as what’s installed on the ducted ac units. This means users may need to replace their air filters more frequently or suffer poor indoor air quality. Some homeowners may need to invest in air purifiers to boost their indoor air quality.

Aesthetics

Ductless mini-splits are often installed indoors and at or above eye level. They also have a line that runs directly from the indoor to the outdoor unit, passing refrigerant between them. This connection may often appear hideous and may damage the indoor aesthetics.

Drainage

Drainage is a huge problem that many users have complained about. The air conditioning system extracts humid air, condenses it, and passes it off as water vapor. The water vapor passed out of the system can lead to a major drainage issue. It can also lead to water damage when not properly addressed.

Initial Price

What your ductless mini-split system promises in energy saving may be lost to the initial price. Purchasing a ductless mini-split system is largely expensive, thus scaring most homeowners from making the decision.

Maintenance

The ductless mini-split system requires regular maintenance to keep it working at high-efficiency levels. In addition to this, you need to consider the cost of changing the air filters to keep your indoor air quality at an all-time high.

Pros of Central Air System

Lower Initial Purchase Cost

Unlike the ductless mini-split that costs an arm and a leg, the central air often costs less upon purchase. It is important to note that the central air system isn’t cheap. However, it’s a more affordable option than the ductless mini-split.

The installation costs may also be lower, especially for homes with existing duct systems that do not require modifications.

Size and Range

Unlike the smaller ductless mini-splits, the central air system is often larger and designed to cater to larger areas. Homes may leverage one central unit for their heating and cooling unit, unlike the ductless mini-split, where they may need as many as eight heads to cover their cooling needs.

Integration With Air Quality Products

The central air system has a robust air filtration system that guarantees improved indoor air quality. This cannot be said for the ductless mini-split system. The ductless mini-split often requires constant maintenance and air filter changes to keep the indoor air quality at the highest level.
In addition to a robust and highly efficient filtration system, the central air system has an array of integrated air quality products available as add-ons for the whole home.

More Options

Central air conditioners are available in different options for homeowners to choose from. Property owners can select the most appropriate heat pumps, air conditioners, and furnaces to meet their specific needs. These options are also larger than the existing mini-split options and cater to a larger area in the home.

Cons of Central Air System

Increased Running Costs

One major disadvantage you’ll quickly notice from using the central air system is the spike in utility bills. If you’re coming from a mini-split to a central air system, you’ll most likely be shocked about how much you’re spending on heating and cooling. While the central air conditioning system may be cheaper to buy, its running cost is higher than that of the mini-split unit.

Duct Maintenance

Although the central air system is hardy and doesn’t require as much maintenance, you still need to invest in the regular maintenance of your duct system. Failure to properly maintain your duct system can lead to clogs that pressure your HVAC system. This increased pressure can cause increased utility bills and increased wear and tear. Duct maintenance should be done regularly to keep your indoor air quality up, reduce pressure on your system, and prolong its lifespan.

Temperature and Zone Control

Unlike in the mini-split system, where each zone in the home has control over its temperature, the central air delivers the same temperature across the home.

For clarity, the central air conditioning is a one-size-fits-all heating and cooling solution, whereas the mini-split is more flexible. This can create problems within the home, especially when people cannot agree to enjoy a certain temperature level.
