Final Verdict: Best Ductless Air Conditioner for Your Money

Pioneer Air Conditioner WYS012-19
Pioneer Air Conditioner WYS012-19

The best ductless air conditioner for your money won’t exceed your budget yet offer all the features you need. The Pioneer Air Conditioner WYS012-19 meets this description with its reasonable price, reliability, low running cost, and amazing cooling features, making it our pick for the best ductless AC on the market.

How to Pick The Perfect Ductless Air Conditioner For Your Needs?

There are various types of split unit air conditioners on the market from various brands, and each one comes with its own unique set of features and benefits. Keep the following in mind when shopping if you want to get the best ductless air conditioner for you:


Higher-end ductless air conditioners typically generate more cooling and have more features. They also cost more than regular models. The cheapest models are often less durable and reliable for effective cooling.

To pick the right one, go for one whose price tag falls within your budget and offers all of the features you need to the degree you need them.


Do you need a ductless air conditioner that can cool multiple rooms or just one room?

If you need one for multiple rooms, you don’t have to buy multiple air conditioners. There are models like the PIONEER Air Conditioner WYS020GMHI22M2 that can cool two to five rooms at the same time.

Such air conditioners come with one outside unit (the engine) and multiple indoor units/sections that you can install in different rooms. You can control each indoor unit separately without affecting the performance of the others.

Multi-split unit air conditioners are far more energy and cost-efficient than installing different air conditioners for separate rooms.

But if all you need is air conditioning for one room, then you can go for a single-zone ductless air conditioner.

Power / BTU Requirements

BTU (British Thermal Unit) represents the cooling power of an air conditioner. The higher the BTU of a cooling unit, the higher its ability to cool a room.

To find an air conditioner that’s powerful enough to adequately cool the room you need it in, go for a unit with enough BTUs to cover the space. For example, cooling a 150 square feet room will require a unit with 5,000 BTUs, while a 500 square feet room will need 11,000 BTUs. One thousand square feet will require 18,000 BTUs.

To be on the safe side, and for maximum cooling, always go for an air conditioning unit that offers slightly more BTUs than you need, not less.


The bigger the size of a room, the bigger the air conditioner you’ll need, and the more energy it will consume to cool that room. High energy consumption equals high electricity bills, which can be a real financial burden.

If you want to be able to use your ductless AC with fewer worries about energy bills, go for an energy-efficient one. Energy-efficient ductless air conditioners typically have an Energy Star certification as proof.

Another way to verify the energy efficiency of an AC is its SEER rating. The higher the SEER rating, the better. More energy-efficient models have SEER ratings between 17 and 20.

Ease of Installation

Split unit air conditioners are generally easier to install when compared to central air units. Some are so easy to install that you can do it yourself, while others require the expertise of an HVAC contractor.

If the installation of an AC requires a professional, make sure to hire someone familiar with the model. If not, a poorly done installation will affect the AC’s performance and may even void its warranty.

The more complicated a split unit is to install, the higher its cost of installation will be.

To save money, go for a model that’s as easy as possible to install and comes with all the components that are necessary for installation. It’s cheaper, and you’ll have fewer worries about something going wrong during or after installation.


Various factors affect the longevity of a ductless air conditioner, including its installation, how intensively you use it, and the quality of its components. Since purchasing and installing a ductless air conditioner isn’t cheap, it’s best to go for a model that will last for years without complications.

The more durable a model is, the less you’ll have to worry about costly repairs or about having to replace the whole system. Customer reviews and the opinion of HVAC contractors are good places to find out about the durability of an air conditioner model.

Also, to be on the safe side, opt for an option with an extended warranty. That way, if something goes wrong, the cost of its repair or replacement won’t be on you.

Extra Features

Some air conditioners, especially high-end ones, come with additional features for your convenience. Some of the most important extra features include remote control, programmable timer, and reusable filters. Any good air conditioner should at least have these features.

Other useful features include a dehumidifier and heating feature. These features will probably increase the price of the air conditioner, but the extra expense is definitely worth the comfort.
