How Do Ductless Mini Split Systems Work? 

A ductless mini-split air conditioner functions similarly to a standard central air conditioner but without the ducts. How is this even possible? How do ductless mini-split systems work? In the article below, our HVAC contractors in Minneapolis, MN, share the must-knows of mini-split A/C systems. 

How do Ductless Mini-Split Systems Work?

Warm air from your home is blown over cold evaporator coils by the indoor unit. A/C refrigerant that circulates through these coils absorbs heat from the air and transports it to. The outside unit is where the refrigerant dumps all of the heat it has extracted from the air in your house. The indoor unit of a traditional split system air conditioner is now housed in the attic or closet. Ducts transport air from your home to this central location, where it is cooled and then returned to your home via additional ducts.

However, in a mini-split ductless system, the unit isn’t located outside. It’s located in the space that’s being cooled. The presence of the indoor device in the space removes the need for air ducts. The indoor device actually draws warm air from the space it is in and blows cold air back into it.

Can a Ductless Mini Split System Cool a Whole Home?

Many Twin Cities residents ask if ductless mini-split systems can cool the entire home. Our A/C contractors are happy to share that these A/C systems can cool your whole home. Additionally, it’s recommended that customers have multiple indoor units that are linked to a single unit. 

Benefits of a Ductless Mini Split

A ductless mini-split air conditioner has many benefits over a conventional central air conditioner. Here are the following advantages of installing a ductless mini-split system

Installation Made Easy

One of the biggest advantages of ductless mini-splits is easy installation. If you’re adding air conditioning to your space or home that doesn’t already have ducts, mini-split systems can be a perfect alternative to the cost of building a lot of ductwork.

Can Be Used for Heating & Cooling

The majority of ductless mini-split systems are heat pumps. That is, they can both heat and cool your house, removing the need for a separate heater. Want to learn more about heat pumps? Contact our heating and cooling company in Minneapolis for more information. 

Zoning

Since these types of A/C systems do not need ducts, you’ll also get the benefit of zoning. Each area of your home will have its own indoor unit. So, you’ll be able to adjust the temperatures of each room separately. In contrast, traditional air conditioners will cool your entire home, whether you’re using that space or not.

Improved Energy Efficiency

When you choose to have a ductless mini-split system installed, you won’t have to worry about any air escaping in the vents or ducts. Our friends at Gilmore Heating, Air, and Plumbing, an air conditioning company in Sacramento, agree that you’ll have more cold air, and you’ll be saving energy since your system will cool your space faster. According to Energy Star, anywhere from 20-30% of airflow is lost within the home’s duct system due to gaps or leaks.

Are There Disadvantages to Ductless Mini Splits? 

Sure thing. Ductless systems are typically around 30% more costly than central air conditioners—but keep in mind that doesn’t include ducts.
