Looking to beat the heat, but without breaking the bank? We’ve got the lowdown on 5 cheap window air conditioners under $100, $200, and $300.

Window air conditioners are cheaper, efficient to operate in small to medium size spaces, and even cost less compared to their split AC counterparts.

The cheap window air conditioners under 100 we checked out were mostly refurbished units but didn’t list them for two reasons. First, their “refurbished”, meaning they’re older models that have been repaired to a satisfactory condition, and second they come with a short or no warranty period.

So, rather than settling for refurbished cheap window air conditioners under 100, we highly recommend choosing a window air conditioner that offers both top-notch performance, and one that will keep you cool for many years to come!

The TOSOT window air conditioner is brought to you by one of the largest air conditioner manufacturers in the world, so you already know why it grabs the top slot on this list.

It boasts a sleek, minimalistic design, and not only cools, but also comes with fan mode, and can dehumidify your space, so you’re basically getting three appliances for one highly affordable price.

But that’s not all, the TOSOT window-mounted air conditioner comes with a smart temperature control system that uses a thermostat that’s tucked away neatly inside the included remote control.

So, if you’re sitting on one end of the room away with the AC remote from the window, the TOSOT air conditioner will cool the areas based on the temperature around the remote next to you.

Speaking of which, and a feature you’ll definitely not see in cheap window air conditioners under 100 is sleep mode functionality, which adjusts the temperature automatically during use to an optimal number that keeps you comfortable.

Plus, the TOSOT is one of the few air conditioners that comes with two separate horizontal louvers that can blow cool air in two different directions.

You can even activate swing mode with the flick of a button if you want the appliance to blow the cool air at different angles in your room.

To top things off, this AC by TOSOT is Energy Star rated, resulting in efficient cooling without increasing the numbers on your energy bill.

FAQ’s

How much does it cost to run a 5000 BTU air conditioner per month?

The capacity of your AC is represented in British Thermal Units (BTUs) instead of amperage or wattage. However, you will have to determine the amperage rating to figure out the cost to run a 5000 BTU air conditioner. You can usually find the amperage rating on the unit itself or in the owner’s manual under the specifications.

Most window ACs are five amperes, so to calculate the wattage, you simply multiply this figure with the number of volts that are in the electrical outlet, which in most cases is 110-volts.

The final cost of running a 5000 BTU AC will depend on how much your local electric company charges you each kilowatt-hour, where the national average is around 12 cents per kilowatt-hour. After you’ve noted these numbers, use the formula watts x hours of use ÷ 1,000 x cost per kilowatt-hour to determine the cost of running a 5000 BTU AC over a 24-hour period, which is approximately under $2 per full day.

You’re probably not going to run the AC all day long, so use the same formula above, but change the “24” with the number of hours you’d be running the AC each day. You can multiply this by the number of days you’d be operating the AC in a month.

What is the smallest window air conditioner?

The smallest window AC is 5000 BTUs, which is perfect for spaces that measure between 150 sq. ft. In terms of size, small ACs fit windows that measure less than 25-inches wide, and 15-inches in height. But your goal should be to buy a window AC that offers efficient cooling for your space rather than the smallest unit.

Small AC can even cool larger closed areas, but they will run for longer trying to achieve cool temperatures, which will cost you more in electricity bills, and damage the unit’s compressor due to the extra load.

Which is the cheapest window air conditioner?

You can buy cheap window ACs for even 50 bucks at garage sales, but from our research, you can expect to pay $150 or a bit higher for a brand new model with a manufacturer warranty.

How much does it cost to have a window air conditioner installed?

The cost depends on the service you choose, but the national average runs between $350 to $1150 for window AC installation.
