How Cold Should the Air Be Coming Out of Your Mini Split Unit?

When you are using a mini-split unit, it is important to make sure that the air is coming out at the correct temperature.

If it is too cold, you may not be comfortable, and if it is too warm, you may end up spending more money on your energy bill than necessary.

The ideal temperature range for most people is between 68 and 72 degrees Fahrenheit. Of course, this will vary depending on factors such as the climate where you live and the time of year.

How Does a Mini-Split Work?

A ductless air conditioning unit, also known as a mini-split unit, is a type of air conditioner that does not require ducts to be installed in your home.

Instead, it uses a series of small indoor and outdoor units to cool and heat different rooms inside your home.

This type of air conditioner is ideal for homes that are not connected to a central heating and cooling system or for rooms that are not currently cooled or heated by other means.

The mini-split unit works by extracting heat from the indoor unit and releasing it outdoors, and vice versa for the cooling function.

How to Choose the Right Temperature for Your Mini Split Unit

A mini-split unit is an excellent option for many homeowners, but it is important to ensure that you are using it correctly.

The ideal winter temperature to set your unit is 68 F, while summer demands a higher number of 78 degrees. This is due to the hotter weather and the fact that you will want your home to be as cool as possible.

If these ideal temperature settings don’t work for you, remember that you can always adjust the temperature to find what is most comfortable for you.

Just keep in mind that if you set it too low, you may be using more energy than necessary to cool your home.

What Happens if You Have the Wrong Temperature Settings?

In general, the wrong temperature settings on your mini-split unit can lead to a number of problems. For the people inside the room, the temperature may be too cold or too hot, leading to discomfort and health problems.

For the unit itself, if the temperature is not set correctly, it can lead to shortened life spans and increased energy bills.

This may also lead to the unit not working properly, causing repairs and damage to your cooling and heating system itself.

Tip: Depending on your mini split’s manufacturer, you may be able to adjust the fan speed. Doing so can help make your unit more comfortable by cooling or heating the room faster.

Your instruction manual will also advise on the best fan speed for your unit. Use this as your baseline and adjust as needed.


Mini split or ductless air conditioning units are becoming more popular each year. As the cost of these systems comes down, more people are able to take advantage of their many benefits.

When choosing a mini-split unit, it is important to make sure that you are using it in the correct way and at the correct temperature.

When set properly, a mini-split unit can save you money on your energy bill and keep you comfortable all year long.
