How to Choose the Best Window Air Conditioner

Updated on November 8, 2017

Pick the Best Window Air Conditioner You Are Looking For

The least expensive and simplest way to cool a home is often with a window air conditioning unit. They usually cost between $100 and $350, and don’t need to be professionally installed – be aware, however, that they are heavy so you may need help installing it. On the other hand, central air conditioners can cost several thousand dollars just for the equipment, not including installation costs. Portable air conditioners are another option at between $300 and $500, but they aren’t as efficient at cooling as window units and so they are a smart choice only for people who can’t install a window unit.

Room-sized air conditioner units are usually installed in a window, but some can be mounted permanently in a wall. Installation in a wall is much more complicated than mounting in a window and usually requires a professional. I wasn’t able to find any professional reviews for wall-mounted AC units; therefore, this report looks only at window units from the best window air conditioners.

What to Look For When Buying a Window Air Conditioner


The most crucial factor to consider when shopping for a window air conditioner is size. Experts say that matching the size of the unit with the size of the space you want cooled is of utmost importance. While smaller units may be cheaper than a larger one, they often are not strong enough to cool a large room. However, don’t go too far in the other direction and buy a unit that is more than you need for your space. An AC that is too large and powerful will cool your room too quickly to remove humidity from the air, and you will be left with a cold and damp room.


Best window air conditioners now on the market do a very good job of cooling a space, provided you have chosen the right size unit for that space. Be aware, however, that units can vary widely in how well cooled air is distributed around the space, as well as differing in efficiency. An air conditioner’s energy efficiency ratio (EER) is merely its cooling output, as measured in BTUs (British thermal units), divided by its power use as measured in watt-hours. A higher EER rating means lower utility costs for you.

Energy Star Label

A simple means of finding the most efficient products is to seek out the Energy Star label. Air conditioners featuring this label are at least ten percent more efficient than units that haven’t earned this distinction, and are only slightly more expensive to buy.

Ease of Use

Ease of use and noise level are the next most important factors to take into consideration, after efficiency and performance. Ease of use means factors such as simple controls, easy installation and understandable controls. Noise level is especially important when shopping for a window air conditioner for a bedroom.

Below are the some top rated best window air conditioners from Amazon on which I've tried to share my opinion with merits and demerits.

Keystone Window-Mounted Air Conditioner

If you want a top-rated window-mount air conditioner, I suggest this unit. It's one of the best window air conditioners.

Bar none, this is the highest-quality window air conditioner I have ever operated. Every part of the unit is well designed. The control panel, the fan blades and the compressor designall combine to make a nice unit that runs at a frequency and decibel level that is easy to take. Its craftsmanship is more than you would expect for the unit’s price range – the company’s gamble has paid off in spades. The remote is great, as well.

When the low price is taken into account, this is truly a remarkable unit. Even with shipping costs it actually costs less than the 5,000 BTU GE air conditioners carried by Walmart - it has a warranty two times as long, is more energy efficient and boasts more features as well. It has a compact size and vents that face forward instead of facing up like my last unit. The energy saving and automatic modes function well also. The “follow me” remote works like this: you can check the temperature in the room using the remote by turning on the “follow me” mode. This activates the thermostat in the remote, and the remote transmits this information to the unit. If you leave the remote at the far (and warmest) end of the room, the unit will continue to run until that end of the room is the desired temperature. The bottom of the case is made of plastic, which is a plus because it won’t rust when water collects there. There are no guards in the back of the unit to protect the fins so care must be used when installing it in the window – this was one of the few aspects of the unit that I didn’t like. Many of the models on the market today also lack these metal guards, so this is not an unusual thing. I would buy this Keystone window air conditioner several times over.

Frigidaire FRA052XT7 Mini Window Air Conditioner

Frigidaire FRA052XT7 is also one of the best air conditioners. Price was my main motivation for buying this unit, but it has surpassed my expectations in every way. It can easily keep the three downstairs rooms of our house cool (about 600 square feet), and this without using the “high cool” setting. It’s also surprisingly quiet. You won’t be sorry choosing this unit.

My last window air conditioner was an LG 10,000 BTU window unit that was terribly heavy. Every spring and fall when I would install or uninstall the unit I was sure I’d drop it out the window, and this did eventually happen. This unit’s high rating and much lower price induced me to try it and I was pleased and surprised to find it works just as well as my old behemoth.

My bungalow house has a room on the top floor which is about 450 square feet. There aren’t enough vents in that room for my (perfectly fine) air conditioner to keep it cool, and at an outside temperature above 80, the room is stifling. This 5,000 BTU unit does a fine job of keeping the room cool even at outside temps in the 90s. It works just as well as my old air conditioner, but it is smaller and cheaper. I think it must be considered one of the best window conditioners. I don’t worry about dropping it out a window, but I could buy another one of these units and still have paid less for both than I paid for my old unit. Frigidaire window air conditioner works wonders considering its cost.

Frigidaire FRA054XT7 Window-Mounted Mini Room Air Conditioner

The Frigidaire FRA054XT7 Window Air Conditioner can cool a room of up to 165 square feet. This lightweight and compact window unit is perfect to use in offices and homes.

Most customers will look at energy efficiency when comparing the best window air conditioners. The Frigidaire FRA054XT7 Window-Mounted Mini Room Air Conditioner was designed to appeal to the average shopper. This unit boasts an Energy Star designation, which means you can eat and still pay your electric bill.

This unit features an easy-to-use touchpad control panel as well as a full-function remote that operates all the features of the unit from anywhere in the room. There are two fan speeds and a temperature range from 60 to 90 degrees Fahrenheit to choose from, so you can set your unit to just about any desired temperature. In auto fan mode, the unit runs the fan at high speed until the desired temperature is reached then automatically switches to the lowest fan speed until the thermostat registers that the temperature has risen, at which time it switches to high speed again. When you don’t want to cool the room but want the air to circulate, you can use the unit as a fan. With the 8-way adjustable louvers you can send the cool air to any part of the room. This unit’s light weight fixed chassis lets you install it in any double-hung window, provided the opening is at least 13 inches high and 23 to 36 inches wide. The FRA054XT7 Frigidaire 5,000 BTU Window-Mounted Mini Room Air Conditioner features a one year full/five year sealed system warranty and a washable antibacterial filter, and it plugs into any standard 20-amp wall outlet. So this unit also holds the reputation among the best window air conditioners in the market.

Advantages of Window Air Conditiners

Window units operate by cooling and circulating the air in a room. Both these functions are accomplished by a single unit that is installed in an open window. The main advantage of these products is their extremely low price compared to a central air system. Newer models tend to be very efficient and good for your electric bill. Installing a duct system is not something you have to worry about doing, and this makes them convenient. You can find a newer unit that is thin and low-profile so it doesn’t occupy your whole window. Newer models also often feature automatic settings and remote controls.

Disadvantages of Window Air Conditioners

One of the big disadvantages of window air conditioner is that they are often very loud. The noise level can often prompt people to not use them at night, and then find themselves tossing and turning in a hot room. Window units that are older can be very inefficient and cost a lot to run, compared with newer models. You will also lose the use of the window that has the unit installed in it. Your local servicer of air conditioning can assist you with any further questions about window units.

So, that's it what I'm exactly trying to find out from the best window air conditioners in today's market. You may choose whatever you like but to me, this list of window air conditioner gets priority first no doubt.
