When researching and testing air conditioners to find the best options on the market, you will inevitably evaluate them on efficiency, ease of installation, noise level, value, and range of settings. 

Which is the best AC? Overall the LG 6,000 BTU Window Air Conditioner with Remote Control, is highly rated as it is energy efficient, easy to use, and quieter than other models.

Below is our list of some of the best air conditioner units.

Best Overall: LG LW6019ER 6,000 BTU Window Air Conditioner with Remote Control

Buy it on Amazon

If you are looking for a sleek, energy-efficient AC at an affordable price then look no further than the LG LW6019ER 6,000 BTU Window Air Conditioner. This model is rated at 6,000 BTU, and comes in seven sizes that range up to 24,500 BTU. This is enough capacity to cool down a space over 1,500 square feet, allowing you to find the perfect fit for your home. The unit offers three cooling speeds, three fan speeds, a 24-hour on-off timer, and an energy-saving function. Because of this versatility it is an excellent fit for almost anyone looking to cool down their space.

This unit is fitted with four-way fins giving you the ability to direct the cool air exactly where you want it. The air conditioner comes with a remote, so you can adjust the settings from anywhere in the room. It hums away at about 48 decibels on low speed, this is roughly the noise level of a quiet office. If the power ever goes out during operation, the AC will start back up when it’s restored, thanks to its Auto Restart function. 

The LG LW6019ER Window Air Conditioner is a wonderful piece of machinery, but its not perfect. Many reviewers have found its installation instructions vague, and have reported set up challenges for those unfamiliar with window ACs. You will also notice that the larger sizes (18,000 BTU and up) require a 230-volt outlet, which isn’t available in all homes.

Best Budget: GE 5,000-BTU Mechanical Window Air Conditioner

Buy it on Amazon

The GE Mechanical Air Conditioner, offers you affordability, performance and value. It is a basic, compact unit weighing just 36 pounds but gets the job done.

Because this GE window unit is a budget-friendly pick, it doesn’t have an energy-saving mode, nor is it Energy Star-certified.

In that case, the Midea U-Shaped Inverter Window Air Conditioner is one of the quietest models you’ll find, operating at just 42 decibels.

The Midea is not without cons. The design makes it tricky to install and you’ll need some help with this including watching the brand’s installation video to get a better idea of how it works. Additionally, the display doesn’t dim or turn off, which can be a bit bothersome in dark rooms.

Best Wall: Keystone 12,000 BTU Through-The-Wall AC

It has three cooling and fan speeds, an auto-swing air vent, and you can set it to turn on and off automatically with its built-in timer. The AC even comes with a built-in accessories tray that allows you to keep the vent hose and window kit neatly stored when it’s not in use.

Best Ventless: Hessaire MC37M Portable Evaporative Cooler

Buy it on Amazon

For low humidity climes, you can often use an evaporative cooler (also called a swamp cooler) instead of your traditional air conditioner. The Hessair MC37M Evaporative Cooler has the capacity to cool down an area up to 950 square feet. It is much more affordable than an air conditioner offering similar coverage. This Hessaire is lightweight and straightforward to operate, and it can be hooked up to a garden hose for continuous filling and uninterrupted operation.

It offers airflow of up to 3,100 cubic feet per minute (CFM), and its 10.3-gallon water tank offers up to four hours of operation if you manually fill it. The Hessaire Cooler has cons as well and these include: it won’t work well if you live somewhere with high humidity levels, and because of its large, clunky design, it is not the prettiest tool in the shed.


How to buy the best AC


The style that suits you is a major determinant of the type of air conditioner you will purchase. There are a variety of options available, varying in cost, capability, and installation requirements.

The two options for occasional users are portable and window air conditioners. They are inexpensive and can be easily installed without professional help. The challenge these options pose is that they’re typically only powerful enough to cool one room at a time, so you’ll need multiple units if you want air conditioning throughout your home.

A through-the-wall or built-in air conditioner is also an option, albeit a permanent style. These styles are installed into a “sleeve” on an exterior wall of your residence. While it is ideal if your room doesn’t have an acceptable window, this style of air conditioner requires a more complex initial installation since you’ll need professional help to cut an appropriate-sized hole in the wall.

The next option on the table is a ductless mini-split system. This is a good, permanent alternative for homes without central HVAC. No ducts are required for this system. It is noteworthy that they are more powerful than window units and are also relatively expensive and complex to install.

The final option are central air systems, which require ductwork throughout your home. These are best suited for newly constructed homes because they are expensive and complicated to install.

Unit Size

For a window or wall unit, it is advisable to measure the height and width of the opening to ensure you pick a compatible appliance. It’s also neccessary to consider its weight, as this will determine whether you’ll need help moving and installing it. The most powerful AC is not automatically the right one for your space. This is because installing an oversized unit can negatively affect your room’s humidity, and you’ll have to turn it on and off constantly.

Room Size and Location

It is important to consider where you plan to put the air conditioner and how much square footage it needs to cool. The amount of heat an air conditioner can remove from a room is measured in BTUs or British Thermal Units.  The larger the room, the higher the BTU. Below is a listing of the recommended room size and BTU:

  • 100-300 square feet: 5,000-7,000 BTU per hour
  • 300-450 square feet: 8,000-10,000 BTU
  • 450-550 square feet: 10,000-12,000 BTU
  • 550-700 square feet: 13,000-14,000 BTU
  • 700-1,000 square feet: 18,000 BTU
  • 1,000+ square feet: 20,000 BTU and up

You’ll also want to consider the room’s location as you decide what BTU is best. Rooms that get hotter will need a more powerful air conditioner. Experts recommend increasing the BTU by at least 10 percent in this situation. 

Noise Level

You should take note of how much noise your air conditioner produces. A standard air conditioner operates between 40 and 60 decibels. The quietest air conditioners operate at around 35 to 40 decibels, and their noise level is compared to that of a desk fan.

Frequently Asked Questions:

Q: How do air conditioners work?

An AC extracts air and filters out any dust or impurities. That air is then passed over the cooling or evaporating coil, and the coil absorbs the heat. Moisture from the air is then reduced to dew on the surface of the coil, this action decreases the humidity level in the room. Finally, the air is pushed back out of the device, lowering the room’s overall temperature.


Q: How much does an air conditioner cost?

The cost of an AC is dependent on type and functionality and you can spend anywhere from $100 to several thousand dollars.


Q: What are BTUs?

A BTU is a British Thermal Unit and it refers to the amount of heat an air conditioner can remove from a room.



Finally, as a homeowner, there are things you will want to take into consideration when deciding which is the best AC unit to install in your home. This is determined by what you value the most. The major factors for most homeowners will be the total cost, lifespan of the AC unit, warranties offered, energy efficiency, and size of the unit you need.
