Ductless Mini-Split vs. Window Unit AC

Posted by Wattson on Mar 14, 2022

Standard window air conditioning units have been around for many years and are a common way to cool a room. But did you know that there are other alternatives to cooling your house? Ductless mini-splits are becoming an increasingly popular choice for cooling and heating room in your home. There are several reasons why ductless mini-splits are better than window unit ACs, which we will discuss below.


What is a Ductless Mini-Split System, and How Does it Work?

A ductless mini-split system is a small, wall-mounted unit that cools or heats a single room. The unit has two main components: an indoor air-handling unit and an outdoor unit. The indoor air handlers can be mounted on the wall inside the room and blow air into the space without duct work. The outdoor unit, which contains the refrigerant tubing, suction tubing, and condensate drain, sits outside the home and takes in air from the environment to cool the indoor unit. You can install multiple indoor units to heat, cool, and customize the comfort level in numerous rooms with one system.


Ductless mini-splits offer several benefits over window unit ACs:

  • Mini-splits are more efficient than window units, using less energy to cool or heat a room.
  • They are quieter than window units, so you don’t have to listen to loud machinery while trying to relax or sleep.
  • They provide more evenly distributed cooling or heating than window units, which means the room is more comfortable to be in.
  • They are more versatile than window units and can cool or heat a variety of spaces, including bedrooms, living rooms, home offices, and sunrooms.
  • Mini-splits provide better indoor air quality.


How Do Ductless Mini-Split Systems Differ From a Window Unit Air Conditioner?

Window unit ACs require a hole to be cut in the window to sit in the window. Then, ductwork must be run from the unit to the outside of the home. Ductless mini-split systems do not require any duct work because they mount on the wall inside the room. This means that you can install a ductless mini-split system without having to do any significant construction or damage to your home.


Which One is Right for Me?

Window unit ACs are an excellent choice for people who need to cool one or two rooms in their homes. Suppose you have multiple rooms that you want to cool with a single system. In that case, ductless mini-split systems are a better option because they are more efficient and provide more evenly distributed cooling and individualized cooling for each room in your house.

Ductless mini-splits are also a good choice for people who want to heat AND cool their homes because they can be used to heat rooms in the winter. If you are only looking to cool your home, window unit air conditioners are a less expensive option than ductless mini-splits.
Mini-splits are more expensive than window air conditioning units, but they provide more energy savings. You can check the seasonal energy efficiency ratio to see how much energy is needed to provide a specific cooling output.


What Are the Pros and Cons of Each Type of System?

Here are some pros and cons of a window unit AC system:

  • Pros: Inexpensive, easy to install, can cool one or two rooms.
  • Cons: They take up window space, the noise level is high, and not as energy efficient as ductless mini-splits.


Here are some pros and cons of ductless mini-split systems:

  • Pros: More efficient than window units, quiet operation, versatile, and can heat and cool various spaces with one outdoor unit.
  • Cons: More expensive than window units.


How Much Will it Cost to Install a Ductless Mini-Split System in My Home Compared to a Window Unit AC?

The cost of ductless mini-split systems varies depending on the size of the unit, but they are generally more expensive to install than window units. The average cost to install a ductless mini-split system is between $1,500-2,000, while the average price to install a window unit is a few hundred dollars.

Ductless mini-splits should be installed by a professional, which can be an additional expense. You could install a standard AC unit yourself if you know what you’re doing. Another expense to consider is the regular maintenance of your system. Both provide easy maintenance to stay comfortable all year round.


Which Is More Energy-Efficient: Ductless Mini-Splits or Window Unit Air Conditioners?

A window unit air conditioner is less efficient than ductless mini-split systems. A ductless mini-split system will provide more cooling for your home while using less energy; even a large home if it has the appropriate BTU rating. What is a BTU rating? It is a British Thermal Unit, and it is a way to measure the cooling power of an air conditioner.

Ductless mini-splits also have a higher SEER rating than window unit cooling systems – meaning they use less energy to cool your home. The SEER rating measures how efficiently the equipment performs over time. Standard air conditioning units use more electric current to power the system than a mini-split.
