A room without an air conditioner to keep you comfortable when the climate starts to warm up is indeed going to be unconducive for any being. For this reason, today’s market is heaped with air conditioners to chill out those humid days. Again, you will need nothing but the best air conditioner to put you at ease like a bug in a rug. 100% cozy!

If you’ve landed on this page in the bid to find the best air conditioner, you should be grinning from ear to ear now because your search has perished.

Let’s say you are hunting for the best air conditioner that will cleanly beat the heat, or perhaps you are looking to replace an old, leaky air conditioner that is threatening to choke you with dirty air.

This post is loaded with a detailed list of the best air conditioners that are known for optimal comfort and can effectively direct cold air to every warm corner of your living or office space.

Best Air Conditioner Buying Guide

It is possible to find the best air conditioner that will effectively and efficiently beat the heat without burning your wallet and still get to keep the earth green if you follow this in-depth guide to buying the best air conditioner.

These three factors are the ultimate things to have in mind as you shop for your ideal air conditioner.

1. Type

There are different types of air conditioners in today’s market, including the mini-split system, wall/window, and portable air conditioners.

Mini-Split system air conditioners come with an indoor unit and an outdoor compressor that is connected by pipes and contain refrigerant gas. With the indoor units installed in every room in your house and controlled by the compressor, this type of air conditioner is overly efficient and superb in terms of offering optimal comfort for the whole house.

Window/Wall air conditioners are the most common and come as a single unit designed for double-hung windows or installed through an external wall. This type of air conditioner is best if you are on a budget or have rooms of 450 up to 550 square feet that need cooling.

Finally, the portable air conditioners tend to be a popular choice today and can be moved from one room to another, unlike the other three, while using a flexible hose to vent hot air outside. If you live in an apartment where a built-in air conditioner is not achievable, a portable air conditioner is the best option.

2. Room Size

When an air conditioner matches your room size, there is sure to be a balance in temperature and humidity. For this reason, be cautious of the room size you want to cool; by so doing, you will bring home the ideal air conditioner.

To avoid wasting electricity costs, take the measurements of the room size in square feet to confirm how effective the air conditioner you will install in the space will be. Look out for the cooling capacities of an air conditioner, indicated in BTUs (British Thermal Units). In cases where your room size is from 150 up to 250 square feet, the best air conditioner with 6,200 BTU can efficiently cool it, or your room size is at 550 up to 700 square feet, be alert for the best air conditioner with 14,000 BTU.

There are other special considerations to take note of if you desire a balance in your new air conditioner and room size. In an instance where you want to install the air conditioner in a room that is occupied by more than two persons, make sure to add 600 BTU for each person. A space that is often sunny will need about 10% more power but lesser power if the room gets little or no sunlight. Also, if the air conditioner is for the kitchen, after taking your measurements and have found the right air conditioner for it, make sure to add 4,000 BTU.

3. Features

The days of air conditioners with fewer convenient features are slowly hitting an end. These days, air conditioners come with features to improve performance and efficiency.

You will find the best air conditioners with remote controls to adjust the temperatures of your air conditioner without having to move an inch, digital displays, a timer to customize the operation of your air conditioner, fresh-air intake to offer ventilation with zero cooling, and dehumidifying mode to keep you in one piece during humid yet cools you during spring and fall.

Some air conditioners have smart controls to adjust the temperature with an app on your smartphone, regardless of your location, and even voice controls.

A more important feature of the best air conditioner is the ability to direct cold air to the needed corners of the room. Not very many air conditioners on the market use adjustable louvers to steer air flow vertically or horizontally. While shopping for the best air conditioner, ensure that the air conditioner can direct cold air evenly despite the obstacles in the room.

Therefore, in your chase for the best air conditioner, look for features that will save you money and bring convenience to the center of your home.
