Is a Ductless Mini Split System Right for You?

You’ve probably seen a ductless mini-split air conditioner system, but chances are you didn’t know it. While they’re fairly rare in homes, they are incredibly useful in many places including office buildings, apartments, and institutions. Unfortunately, mini-split AC units break down on occasion, just like regular AC units.

In this article, you’ll discover what ductless mini split AC systems are, how they work, how people go about fixing them, and when they’re the best option for installation. So, if you’re wondering about mini-split systems, you’ve come to the right place. 

Ductless Mini Split vs. Standard AC System

ductless mini splitAs the name implies, ductless mini-split ac systems are basically AC systems without ducts. Standard AC systems use ductwork throughout the house to deliver cool air to various rooms. Mini-split systems, on the other hand, consist of small units installed in each room that needs cooling.

These indoor units run off of a central outdoor unit, much like a regular AC system. Typical ductless mini-split systems can have up to four indoor units running off of one outdoor unit. These indoor units are typically installed in a wall, although there are stand-up units on the market.

While the upfront cost of installing a ductless mini-split system is high for buildings with an existing duct system, it is often much cheaper than installing ductwork in an entire structure. 

Saving Energy Without Ducts

Plus, without ducts, mini-split systems use less energy than a traditional system because ductwork accounts for almost 30% or energy loss in an average home. The air is delivered right into the room by the unit, so it doesn’t have the chance to burn energy going through ducts in a hot attic or walls.


HVAC techs are well versed in fixing and maintaining mini-split units. As part of a regular maintenance routine, they’ll check your drain pan, inspect the evaporator coils, clean indoor air quality filter components, and balance your blower assembly and fan wheel.

Common Ductless Air Conditioner Situations

The same goes for older homes with no existing ductwork, multi-family homes, or small apartments. If you have a stand-alone garage you’re turning into a studio or apartment, you may want to consider a ductless air conditioner system.

These systems have separate units, so each room can have a different temperature. Mini-split systems usually come with remote controls for operation. This can save money as you can completely turn the unit off in any rooms you aren’t using. 

Ductless AC Maintenance

Maintaining a mini-split system requires a similar amount of attention as a traditional system. You’ll want to clean the filters in each unit annually and check the outdoor unit to make sure it has unrestricted airflow. But, HVAC techs on a maintenance schedule can take care of all your ductless mini-split system needs. 

Like a traditional system, mini-split units should be checked regularly for the best results. If you’re thinking about installing a ductless system, contact your local HVAC experts today.
