Cheap Window Air Conditioner Buying Guide

Shopping for the cheap window air conditioner you can find is sometimes what you really need to do. Your room, office or apartment is sweltering hot and you need inexpensive relief – fast! Fortunately for us today, inexpensive AC’s are available in a variety of places: local hardware stores, big box stores, online and more.

And just in case you think that the lowest-priced models in this review still cost too much, here’s a fun fact: when the very first residential air conditioners hit the market in 1914, they cost between $10,000 and $50,000! Obviously, only “the rich and famous” had them in their homes back then.

Thanks to new materials, many decades of research (as well as trial and error) and modern manufacturing processes, the cost of AC’s have dropped dramatically. Now almost everyone can afford one of these inexpensive models to help cool their home.

Before you actually purchase a window AC, here are several things to keep in mind:

Proper Sizing: Be sure to know what size AC you need for the space you want to cool. Any air conditioner that will sit in a window is exposed to all of the air in that room, as well as the air in any adjoining rooms or hallways not separated by a wall or door. All of that air is what this unit will be trying to cool. Buying an AC that is too small just because it’s cheap will result in a room that is never cool. Measure your room and go shopping informed. See our Window Air Conditioner Reviews and Buying Guide for sizing information and much more. 

How to operate the AC: Research the functions and features of the model you are considering to buy. The three least expensive models in this review have manual controls – knobs to turn, rather than buttons to push. They don’t have touch pads or remotes. If you want a model with a remote – or some other special feature, like WiFi – you can find it in almost any size AC. But make sure that you carefully read the specifications so you won’t be disappointed when you get your new air conditioner.

What are the room conditions? Realize that if a window air conditioner will be subjected to direct sunlight in the afternoon or evening, some of its cooling power will be sacrificed to the extra heat of the sun. The same is true if it’s in a kitchen with the stove or oven on, or if the room has high ceilings – over 9 feet. If you fail to take the sun and other heat sources into consideration, the unit you buy may struggle to meet your cooling expectations.

Know what size you need: Measure the size of the window you plan to use for the AC. Not all windows are the same,  and some of the larger window AC’s may not fit the ones in your house, so measure before you buy.

Most outlets will work: As with all electrical appliances, you will need to provide the proper power to operate them. All of these reviewed models will plug into a standard, 115 Volt receptacle by means of the cord which is attached to the unit.

A Word About Energy Efficiency

It’s nice to know that we can find cheap air conditioners to purchase today. But behind that cool breeze coming across your room is an electric meter that keeps track of how much energy it takes to make that cool air. At the end of the month it will be added to your electric bill.

The smart buyer will look at the bright yellow sticker on the box of the air conditioner he or she is thinking about buying. It is called the Energy Guide Label and is required by law to be there. It will tell you several important things:

• The maker, model number, and size (cooling power in BTU’s) of the air conditioner.
• The Combined Energy Efficiency Ratio (CEER). This is a standard used for window air conditioners. It measures the combined efficiency of the unit when it is in standby and when it’s actually cooling a space. Use this number to compare the unit with others of the same BTU size.
• The estimated yearly operating cost (based on the national average cost of electricity), and the range of operating costs for similar models.
• If it has the ENERGY STAR® logo, it means that this model meets strict criteria for energy efficiency.
• The estimated yearly electricity consumption of the AC.
• The key features of the AC and the similar models to which it is compared.

Cheap Window Air Conditioner FAQs

Here are common questions about the most affordable window ACs. 

Q: Will I need to provide a drain for an inexpensive air conditioner?

A: Not unless you want to collect the water from your AC, or if you don’t want it dripping close to your house. Properly installed, the water removed from the air by the AC will run to the back (outside) of the unit and drip through one or more drain holes. Occasionally, the drain hole(s) can become clogged with accumulated dust or dirt and may need to be cleaned out with a screwdriver or similar tool.

Q: How long will my cheap window air conditioner last?

A: The average lifespan of a window air conditioner is between 7 and 10 years. This can vary depending on how much it is used and how well it is maintained. Keep your users’ manual and follow the maintenance guidelines. This will ensure that you will get the best service from your cheap air conditioner for as long as possible.

Q: Do cheap window AC’s use a lot of electricity?

A: No. Larger units will almost always use more power than smaller ones, but a cheap AC won’t necessarily use more power than an expensive one. Your cost will depend on the BTU size, how much you use it, and what electricity costs where you live. When shopping, look for the CEER number on the yellow Energy Guide Label on the box. The higher the number, the more energy efficient that unit will be for that size air conditioner.

Q: I need a window air conditioner; what are the most important things for me to know to get the most bang for my buck?

A: Before you start shopping, jot these things down in this order:

1. The correct size (cooling capacity) for the room you need to cool (measure the room).
2. The correct physical size to fit your window (measure your window).
3. The features that you want in a window air conditioner.

When you start shopping, look for:

• The highest CEER rating among the models that meet the above requirements.
• The lowest priced model that satisfies all of the above.

By using these points as your guide, you will be able to buy the cheap window air conditioner that will meet your cooling needs.
