Every AC owner's worst nightmare. 👆

First of all, figure out which type of AC best suits your needs and budget.

Check out this full infographic and more info on home cooling from the U.S. Department of Energy! If you're cooling a whole house, you could consider a central or ductless mini-split AC system because they are a lot more powerful and can cool large areas evenly. These tend to be quite expensive and may require professional installation.If you live in a very dry climate, consider an evaporative cooler, which releases moisture into the air for added comfort (like this one).

If you live in a very dry climate, consider an evaporative cooler, which releases moisture into the air for added comfort (like this one).

If you're only concerned with cooling an apartment (or individual rooms), a room AC will probably best suit your needs. These are the three types of units you'll be looking at:

Window units generally are cheaper ($100–$600) than wall units and portable units ($300–$800). The price will also depend on how large and efficient a unit is.Here are some questions to consider:- Do you have windows? - Do you need to move the unit from room to room?- Are you allowed to drill a hole in the wall?- How long are you planning on living in there?

Window units generally are cheaper ($100–$600) than wall units and portable units ($300–$800). The price will also depend on how large and efficient a unit is.

Here are some questions to consider:

- Do you have windows?

- Do you need to move the unit from room to room?

- Are you allowed to drill a hole in the wall?

- How long are you planning on living in there?

Window units are (relatively) affordable, space-saving, and easy to install and uninstall.

If you have multiple rooms, you may have to install one unit for each room for even cooling. These units usually require a support bracket installed outside the window for security. Get this one from Amazon or Walmart for $239.99 or from The Home Depot for $239.

Also, consider the shape and size of your window when choosing a window unit.

Make sure to measure the height and width of your window opening and check the dimensions of the AC to see if they are a good fit. Look in the description of each unit for the minimum window height as well as the maximum and minimum window width to ensure that the unit won't be too big or small for your window.If you have a sliding or casement window, you may need a specially designed vertical window unit.

If you have a sliding or casement window, you may need a specially designed vertical window unit.

Don't forget to purchase a support bracket if your apartment doesn't already have one.

This is an important safety measure to prevent your AC from falling out of the window and injuring someone! 😱 Also, remember to check that the bracket is made to support the size and weight of your unit — this info can be found in the product description or the electronic user manual.Get the one above from Amazon for $29.99 (supports up to 165 lbs.). Also, check out other options here (up to 80 lbs.), here (up to 85 lbs.), here (up to 105 lbs.), and here (up to 165 lbs.).

Through-the-wall (or built-in) units are harder to install, but they don't take up window space and can be used for windowless spaces. They also have a more airtight fit, which means less energy loss.

You will need to consult your superintendent or landlord about installing one of these units! They require a sleeve, which is a metal device that holds the air conditioner in the wall to support its weight, and this may require professional installation if the room doesn't already have one.Get this one from Amazon, Walmart, The Home Depot, or Best Buy for $431.57.

Portable units are easy to move around from room to room and can be rolled away for storage.

They also vent through an open window and take up some floor space. Some portable units have reservoirs that need to be emptied, while others do not. New units (like the one pictured) can pull double duty — you can also use it as a heater in the winter.Get this one from Amazon for $349.99.

Measure the square footage of your apartment/room to determine how powerful your unit needs to be.

The cooling capacity of an AC unit is measured by BTU (British thermal unit). Basically the larger the room, the higher the BTU you'll need.

BTU measures the amount of heat an air conditioner can remove from the air within a certain amount of time. Higher BTU = greater cooling capacity. BTUs can range from 5,000–20,000. AC units with higher BTUs can cool larger spaces and tend to be more expensive.Choosing the correct BTU that corresponds to the dimensions of your apartment is important because it will ensure that you get the most energy-efficient cooling system for your space.You might think, well isn't the higher the BTU the better??? Not so. While a unit with too few BTUs might struggle with cooling a large room, an AC that's too powerful in a small space will cool the room too quickly without having enough time to dehumidify the air, which will leave you feeling cold and clammy. *Shudders*

Other factors to consider when it comes to choosing the right BTU rating: ceiling height, room insulation, sun exposure, location (like whether it's in the kitchen or bedroom), and local climate.

homedepot.com

As a general rule for rooms with excessive sunlight, select a unit with 10% more BTUs than what is required by the size of the room. If you're placing the unit in the kitchen, select one with an additional 4,000 BTUs than what is required by the room size. For rooms that regularly contain more than two people, add an additional 600 BTUs per person.

Opt for an energy-efficient model, which means lower greenhouse emissions and monthly electric bills.

You can find the Energy Efficiency Ratio (EER) on the unit. EERs range from 8 to 12. The higher the number, the more efficient. Look for the Energy Star label — Energy Star-certified room air conditioners are 10% more efficient than non-certified models. Also, look for units that come with energy-saving/econ settings!

Before you purchase, make sure your outlets match the plug. You'd be surprised at how many kinds of plugs are out there!

Most AC units run on 115-120V and have a standard three-prong/grounded plug. However, there are some that run on 230V and have a special plug that you may need an adapter for.

Also, think about what extra features you'd enjoy (within your budget) — a remote control? A timer? An energy-efficient or quiet mode? The ability to double as a heater/fan/dehumidifier?

For example, this portable unit comes with a remote and has three modes: air conditioner, fan, or dehumidifier (dehumidifying capacity of 101 pints per day, three fan speeds). It also has a 24-hour programmable timer. It uses a special self-evaporating/auto-drain technology, which recycles moisture collected during the cooling process to produce cool air so you don't have to empty the reservoir very often.Get it from Amazon or The Home Depot for $452.99.

You can adjust the air flow in four directions. It can also be installed through the wall. It has a washable, antimicrobial filter.Promising review: "This is an incredible unit. I've owned no fewer than five AC units previously, but this is my first Friedrich. You get what you pay for. I had a chance to look at this unit run with the cover off. Very well designed. It's relatively heavy. Most importantly, it's quiet. True, everyone's definition of quiet will be different. But this unit produces an overall sound that's less of an annoyance and more closely resembles that of white noise. Compressors (not to be confused with the motor that drives the fan) can be very loud. But Friedrich has done their homework here by choosing the right compressor, arranged nicely on dampers, to make a smooth sounding unit that delivers a nice burst of cold air. The automatic swivel distributes the air to a fairly wide cross section of the room." —Jason OakleyGet it from Amazon for $319 or Walmart for $319.95.

BTU: 10,000Suggested square footage: 450 Energy rating: 
10.9Voltage/plug: 115VRemote: Yes
Measurements: 14.5"H x 19"W x 21.5"D It can accommodate windows with a minimum height of 15.5" and width of 23" to 36". In addition to the auto cool mode (adjusts fan speeds as the room temperature changes), this unit also has an energy saver (econ) mode, and sleep mode. It also has a fresh air vent, exhaust control, eight-way air direction, digital thermostat, 24-hour timer, and washable mesh filter with check filter alert. It can dehumidify up to 2.7 pints per hour. Promising review: "I'm very surprised at how well it keeps the ENTIRE apartment a comfortable temperature. The living room where we keep this unit is pretty spacious, and I only expected it to keep that area (and maybe the hallway that leads to the two bedrooms and bathroom) a cool temperature, but it keeps the whole place a comfortable temperature. Obviously, the dining room in the back of the apartment and the kitchen aren't AS cool as the living room, but it's not uncomfortably hot either. I wanted to wait until there was a really hot day to write a review and see how well the AC stood up against it, and it's honestly really great. Get this AC unit!" —J.

While a bit more expensive than a typical, small room AC, I think it's well worth it for two reasons: the aesthetics of how the AC looks (this one looks like it was designed by Apple I think) and how well it would function with the app. Despite some problems setting it up to connect to my WiFi, an issue I think was specific to my router (as this AC hooked up fast and easily to my phone's tethered internet on the first try), this ended up being a great purchase. It really cools my small room extremely well, and I love the fact that you can schedule it via the app to turn on and off when you need it (or turn on remotely so when you arrive it's nice and cool). I would highly recommend this to anyone looking for a bit more of an advanced AC!" —Shaunh20Get it from Amazon for $329 or Best Buy for $329.99.
