Ductless Air Conditioner



A ductless air conditioner normally consists of a wall-mounted indoor unit combined with an outside compressor. 

You can improve the efficiency of the system simply by removing the ducts. 

The inbuilt thermostat makes it capable to control each area with individual temperature.

Pros and Cons of Ductless Air Conditioning Systems


The main advantages of ductless systems are their

  • Flexible placement
  • High efficiency
  • Low noise levels
  • High degree of comfort.

 In these cases, ductless systems can also work as a supplement to central air conditioning systems (like ‘hot rooms’ located upstairs or at a corner).

Another huge advantage of ductless systems is that heat pump models can also provide the required heat. 


  • Cant be installed in every application
  • Some people don’t like wall mounting
  • It can be expensive

Things to Consider Before Buying a Ductless Air conditioner

If you’re around the idea of investing in a ductless mini-split air conditioner, main factors to consider to get the desired product are mentioned below.


Cost is the main downside of buying a ductless air conditioner. If you want a ductless air conditioner that’s powerful enough to cool a large room you have to pay a pretty high amount. 

In addition to the price of the unit itself, you have two main additional costs to factor in — installation and ongoing energy costs. Some DIYers may have the skill to install a ductless air conditioner themselves, but most customers will need an HVAC specialist for help.

The second category is mostly good news. Energy costs with a ductless air conditioner will be lower than any other type of air conditioner providing the same amount of cooling.

Be prepared to expect an uptick in your energy bills if you haven’t been using anything for cooling before.

Number of Zones

You’ll find single-zone ductless air conditioners designed to cool one room and multi-zone models that can work with several rooms.

The cost will go up for each zone you add, but if you live in a house with several rooms you need to keep cool, then making sure you get an air conditioning unit with the right number of zones is important.

One of the benefits of zones is that you can control each one distinctly. A quad-zone air conditioning unit, for example, can be set to four different temperatures based on the needs of people in each of the four rooms.

The same goes for dual-zone and triple-zone units.


Or you can turn the A/C off entirely in any room that’s not currently in use. This cooling strategy will not only save you money but is something that you are unable to do with central air conditioners.

Power / BTU Requirements

The power of all air conditioners is measured in BTUs. The higher the BTUs, the greater space an air conditioner will be able to effectively cool. In many cases, you’ll see a specific room size provided in the specs of a product as well, but you can also do the calculations yourself based on the BTU information they provide.

Energy Efficiency

They are energy star certified. It lets you know that you have a lot of options that perform well regarding energy efficiency.

As you’d expect, if you want to cool a larger space or more rooms, the energy you use will increase. But the option of cooling just the space you’re in will help you keep it low.


A lot of ductless air conditioners use the standard 110-120 volt outlet, but some larger models require a higher voltage.

If you purchase a model that needs a 220 or 240-volt plug, then you’ll have to work with an electrician for an upgrade to ensure you don’t blow a fuse or even cause a fire.

This is an important factor to consider when shopping for an A/C unit. If you’re looking to save on installation costs, then you will need to consider the type of volt outlet the unit requires.

Ease of Installation

You’ll very likely need to call in an HVAC specialist who is experienced in installing ductless vents.

In fact, some ductless air conditioner manufacturers also make professional installation a requirement if you want to take advantage of the product’s warranty.

If you do decide that you’re up to the task of installing it yourself, then make sure to do some research to get an idea for what will be involved.


Obviously, an investment as big as a ductless air conditioner is one that should be for keeps. You don’t want to have to deal with expensive repairs or worse, replacing the whole thing, for many years to come.

Some ductless units come with warranties, so you know you can count on the product for longer or at least get it fixed with minimal cost and trouble. If you’re looking for more durable air conditioning check for portable battery fan which is a more cheaper way to alter your home cooling. 

Reviews and brand reputation can also give you a head’s up to how long units have lasted for other customers. To get a better idea of the best brands, please read the brand section below.
