10 Best Ductless Air Conditioners in 2020 – Reviews & Guide

Do you have an old home without ductwork? Are you wondering how to install air conditioning? Wonder no more, because you can get one of the best ductless air conditioners suited for just your kind of home.

But first things first … What is a ductless air conditioner?

Just as the name suggests, these air conditioners are ductless. The indoor system is installed on the wall of the house. However, the condenser or compressor parts are installed on the outside wall or some distance away to keep the noise level down.

By installing the ductless system for cooling and heating, you could save more than 30% on your energy bills. There is a good reason for this. The traditional air conditioners lose more than 30% energy from leaks or general malfunctions in their systems. This also means that with a ductless system, you will leave a smaller footprint on the environment.

Now that we are agreed that ductless is, or could be the Holy Grail of indoor heating and cooling, what then is the best one to buy?

Here, we will bring you reviews of 10 of the best of them.

How to choose the Best Ductless Air Conditioners?

What should you consider most when buying a ductless air conditioner and heat pump? All of the units that we have reviewed here are also heat pumps. With so many of them, you can be confused. Just see the few most important guidelines below:

Multi-zone or Single Zone unit?

This is an important question and the answer can help you save money. A multi-zone unit is a ductless AC that comes with a few indoor units but all of them corresponding to one outdoor unit. You can buy a tri-zone unit for your home so that you regulate the heating or cooling in three rooms, all controlled by a single outdoor unit.

Single zone air conditioners are just that – a single indoor unit corresponding with the outdoor unit. In our reviews, we have looked at many single zone ones.


Some units cost thousands of dollars and some cost hundreds. The good thing is that there is a unit for your budget. However, note that lowly priced units may lack some important features. Therefore, before you consider the price, check the features.

SEER rating

Some units can have as low as 12 SEER rating while others can have a rating of as high as 30 SEER. The higher this rating is the better. Mini split units such as the ones we have looked at here have SEER ratings of 16 to 25. This rating is a measure of how energy-efficient a unit is when cooling air.


Ductless air conditioners are not the best-looking things to have on your walls but because of necessity, you still have to install it. Check for a unit that can be recessed into the ceiling. At least that one stays out of sight. Other units can be installed on the floor or on the wall. Depending on where it is going to be installed, the wiring and refrigerant tubing should be long enough. Perhaps you can order more.

FAQs about Best Ductless Air Conditioners

Why should I go for the ductless system?

There are many reasons for choosing ductless over traditional heating and cooling systems. One of them is that it is cheaper since you do not need any ductwork in the house. Since the installation is also not too complicated, it is cheaper.

Central heating systems lose too much energy. However, ductless systems have minimal to none energy loss. Therefore, most of them have higher SEER rating.

What is zoned cooling or heating?

This is the process where you can control the temperature of each room individually. With zoned heating or cooling, you can even switch of AC for some rooms so that you save more money. There is no need for cooling an empty room. Check whether the multi-zone air conditioner that you want to buy comes with a remote for each air handler. That way, the occupants of the rooms can control their heating or cooling levels without affecting the other rooms.

How do I install ductless air conditioners?

This should be a question of how ductless air conditioners are installed because it is recommended that you hire an HVAC guy for a job. The reason for that is that if installed a non-professional, it might render the warranty invalid.

To connect the indoor unit and the outdoor one, a small hole is drilled through the wall. This is where the refrigerant pipe will pass. The hole is small, about three inches. The indoor and outdoor units are then installed inside and outside respectively. The indoor one is installed in a space near the ceiling if possible, but some go near the floor.

A power cable, refrigerant line and a drain for the condensate are then connected to both indoor and outdoor units and you are done!

Wrapping Up

The best ductless air conditioners can cost you a substantial amount of money. Therefore, you cannot afford to buy any that you come across in the market. Here, you have seen several reviews of some of the best air conditioners that you can buy for your home. You can choose a multi-zone one or a mini split AC depending on your needs.
