Mini Split AC Vs. Central Air, Which One is Right for You
According to the Energy Information Association, 87 percent of residences in the US have air conditioning. However, many of those homes have the wrong AC unit for their needs! When it comes time to install or replace your home’s air conditioning system, you have a lot of choices to make. How big should your system be? What type of air conditioner should it use? Should you go for Mini Split AC vs Central Air?
It can be tough to decide which type of air conditioning system is right for your home. Central air is a popular choice, but mini split AC systems are growing in popularity. So, which one should you choose?
There is no one-size-fits-all answer to this question, as the best air conditioning system for your home will depend on a number of factors. However, we can help you evaluate the pros and cons of mini-split ACs and central air systems so that you can make an informed decision about which option is best for your needs.
What Is A Mini-Split AC Unit
A mini-split AC unit is an air conditioner that doesn’t require a centralized duct system. Mini-split ACs have two main parts: an outdoor compressor/condenser and an indoor air handler.
A connecting refrigerant line runs between the two units. Most mini-splits have one or two indoor air handlers, but some systems have as many as eight air handlers connected to one outdoor unit.
Mini-split ACs are a popular choice for homes and businesses because they are energy efficient and can be installed in various locations. They are also relatively quiet and don’t require extensive ductwork, saving you money on installation costs.
If you’re considering installing a mini-split AC in your home or business, it’s important to hire a qualified contractor to do the job. Installation is typically not a do-it-yourself project because it requires specialized equipment and knowledge.
What Is a Central Air Conditioner
A central air conditioner is a system that helps to cool your home by using a single unit to remove heat from the indoor air and circulate it back outside. They use ductwork to provide cool air throughout your home or business in every room.
This type of AC unit is typically more expensive to install than other types, but it can be more energy-efficient and provide better cooling power than window units or portable air conditioners. Central air conditioners also help to improve indoor air quality by filtering out dust, pollen, and other airborne particles.
If you are considering installing a central air conditioner in your home, there are a few things to keep in mind. First, you will need to have a Professional HVAC Contractor come to your home to assess the size and layout of your house.
They will need to determine the best location for the outdoor unit and make sure that there is enough space for the indoor unit as well. They will also need to set up the ductwork throughout your home. Once the central air conditioner is installed, you will need to have it regularly maintained by a professional in order to keep it running efficiently.
How Do Mini Split AC Units Operate
Mini-split AC systems are very popular in Europe and Asia and are becoming increasingly popular in North America as well. They are a great option for those who want the benefits of central air conditioning without the need for ductwork.
As we’ve already mentioned, a mini-split AC system consists of two main parts: an outdoor unit that contains the compressor, condenser, and expansion valve, and an indoor unit that contains the evaporator coil. The two units are connected by refrigerant lines.
The outdoor compressor compresses refrigerant, which is then pumped to the indoor unit. The evaporator coil is where this refrigerant goes next. This process removes heat from the air inside your home, cooling it down. The cooled air is then circulated back into your living space by the indoor unit’s fan.
The refrigerant that is used in mini split AC systems does not deplete the ozone layer, making them a more environmentally-friendly option than older AC units that used Freon. Mini-split AC units are also very energy efficient since they use less overall energy to run, depending on your temperature settings, and usually have an eco-friendly mode.
If you are considering installing a Mini Split versus Central Air AC system in your home, contact a Local HVAC Contractor to discuss your options. They will be able to help you determine the size and type of unit that best suits your needs.
How Do Central Air AC Systems Operate
The compressor and fan are the two main components of a central air AC unit. The compressor circulates the refrigerant. The refrigerant is circulated through the evaporator coils, which are cooled by the fan. This causes the refrigerant to evaporate, which draws heat from the air. The cooled air is then circulated back into the home through ductwork.
A thermostat controls the operation of the unit. When the thermostat senses that the temperature in the home has risen above the setpoint, it will turn on the unit. The compressor will start and begin circulating refrigerant through the system.
The fan will also turn on, blowing air over the evaporator coils. This process will continue until the thermostat senses that the temperature has reached the setpoint, at which time it will turn the unit off.
Central air AC units are typically located outside the home, though some units may be located in an attic or basement. The location of the unit can impact its efficiency.
In order to maximize efficiency, central air AC units should be regularly maintained. This includes cleaning the coils and filters and making sure that all of the parts are in good working order. Regular maintenance can help to extend the life of the unit and keep it running efficiently.
Mini Split Air Conditioner vs Central Air Pros and Cons
Now that we have a better understanding of the two different types of units, let’s talk about the pros and cons of each.
Pros of Mini Split AC
1. Easy to Install – Most mini-split ACs come with easy-to-follow instructions, making installation a breeze.

3. Highly Efficient – Mini split AC units are some of the most energy-efficient cooling systems on the market today. Many models boast SEER ratings of 20 or higher.
4. Zone Cooling – With a mini-split AC, you have the ability to cool specific areas or “zones” in your home, rather than cooling the entire space. This can help you save money on your power bills.
5. Quiet Operation – Mini split AC units tend to be very quiet, making them ideal for bedrooms and other areas in your home.
6. Long-Lasting – With proper maintenance, a mini-split AC can last up to 20 years or more.
Cons of Mini Split AC
1. Higher Initial Cost – While mini-split AC units have a higher upfront cost than a window or portable unit, they often make up for it in energy savings over time.
2. Can’t Cool Large Spaces – Mini split AC units are best suited for smaller homes or individual rooms rather than larger spaces like open concept homes or homes with many rooms that you need to keep cool.
3. The Wrong Type of Unit for Your Needs – Having a unit that is too big or that is wrongly installed may result in short-cycling and energy waste, as well as being unable to properly regulate the temperature or humidity.
Pros of Central Air Conditioner
1. Can Cool Large Spaces – Central AC units are powerful enough to cool large spaces like open-concept homes and apartments.
2. The Cost Can Be Cheaper – The upfront cost of a central air conditioner is around 30% less than mini-split systems if you don’t count the ductwork installation.
