Whether you own a window, mini-split, or portable air-conditioner (AC), choosing the right-sized air conditioner for your room is essential for your health.
High heat and humidity can lead to a number of serious and dangerous conditions. People with pre-existing problems, the elderly, and newborn babies are especially vulnerable to such complications.
If you have to cool a larger room you may be especially worried about this conundrum. To help you out, here’s a list of the highest BTU air conditioners for 110/120 outlets!
BTUs for Air Conditioners
Energy Star, the energy-efficiency certification program of the U.S. Environmental Protection Agency, recognizes air conditioners with BTUs between 5000 – 34,000. However, the highest BTU air conditioner that can be plugged into a 120-volt outlet is 15,000 BTU.
A 15,000 BTU air conditioner can cool up to 750 square feet of space, which is more than enough for the average consumer. This is evidenced by the fact that 8,000 BTU is the most popular AC size for residential use.
With that being said, let’s take a look at some common BTU ranges for different types of cooling systems:
Portable Air Conditioners
On 110-120V of power, portable air conditioners can generate between 8,000 – 14,000 BTU. This is enough to cool a room that measures between 320 – 700 square feet.
Given that the average living room size measures 340 square feet, most portable ACs will do a decent job of cooling your room. Because these units are portable, they can also be moved around from room to room, allowing them to serve their purpose in multiple settings!
Window Air Conditioners
Window air conditioners range between 5,000 and 15,000 BTUs when they are connected to a 110 – 120 V outlet. They are an excellent option if you have access to a window and are on a budget.
Window-mounted air conditioners give you the most bang for your buck as they are cheaper and can cool a room more efficiently compared to a portable AC. They are also quieter and come in the largest range of BTUs, allowing them to accommodate a greater variety of room sizes.
Mini-Split Air Conditioners
Ductless mini-split air conditioners are made up of an indoor air-handling unit and an outdoor compressor. Their key advantages over portable and window AC units lie in the fact that they are energy-efficient, and may blend more seamlessly into the decor of a room.
When connected to a 110V – 120V power source, the maximum amount of BTU they can generate is 12,000 BTU, which will cool between 450 and 600 square feet of floor space.
As the most aesthetically pleasing and energy-efficient option on our list, mini-split air conditioners cost more than the window and portable units but are worth the investment to many homeowners.
Highest BTU 110V/120 Portable Air Conditioners
The highest BTU portable air conditioner you can safely plug into a 110/120V outlet is 14,000 BTU. Let’s take a look at some of our recommendations:
