Highest BTU 110V Air Conditioners (Portable, Window, Mini Split ACs)

The size of any air conditioner is limited by several factors. Voltage is one such factor. When looking for high BTU AC units, we usually want to figure out this:

Which is the largest air conditioner for 110 or 115 volts?

Most electrical grids provide 110V, 115V, and 120V voltage by default. What’s the maximum BTU air conditioner we can plug into those voltages?

First, let’s look at the BTU ranges of the most common types of air purifiers that can still run on 110V:

Let’s look at each type separately and provide examples of the highest BTU AC units for each:

Highest BTU 110V Portable Air Conditioners (2 Examples)

Almost all portable air purifiers run on 110V. They can generate anywhere from 8,000 BTU to 14,000 BTU. You can easily move them around (unlike most other AC units).

The ones with the highest BTU output – 14,000 BTU – are powered by 1,300 to 2,000 Watts. We’re talking 10-18 amps.

Here are 2 examples of the 110V portable air conditioners with the largest BTU output:

#1 Whynter ARC-14S 14,000 BTU Dual Hose (Best Unit With Highest Energy-Efficiency)

Whynter ARC-14S can generate 14,000 BTU of cooling power and runs on 110V. It’s one of the best portable AC units overall, with dual-hose and exceptional energy-efficiency.

Whynter ARC-14S is the best example of the highest 110V portable air conditioner. It can be hooked up to any 110V outlet. It’s powered by 1,300W and 11.6A. You can buy it here:

Window AC Units With Highest BTU Running On 110V (1 Example)

Window air conditioners are installed on a window sill. They are less portable than portable air conditioners but they too can use the 110V outlets.

The highest BTU a 110V window air conditioner can generate is 15,000 BTU (you will find one example of 15,000 BTU 110V window AC below).

Window air purifiers can achieve almost 30,000 BTU cooling output if hooked up to 230V. For example, LG LW2516ER running on 230V has 24,500 BTU and Frigidaire FFRA2822U2 can even reach 28,000 BTU on 230V.

#1 Example: Emerson Quiet Kool EARC15RE1 (Highest 110V Window AC With 15,000 BTU)

Emerson Quiet Kool EARC15RE1 is one of the few 15,000 BTU window air conditioners running on 110V. It’s the highest BTU output for a 110V window AC unit.

Emerson Quiet Kool EARC15RE1 has a large 15,000 BTU cooling output, despite running on the standard 110V voltage. Because of the highest BTU at low voltage, it’s one of the most sought after window air conditioners:

Highest BTU 110/120V Mini Split AC Units (2 Examples)

Mini-splits are the most popular split-system air conditioners. The outdoor generator is connected to 1 or several indoor air handlers. 110V mini splits are usually 1-zone mini-split air conditioners.

Running on 110/120V, they can generate a maximum of 12,000 BTU cooling power. 

Here are 2 examples of the highest BTU mini-splits running on 110/120V:

#1 MRCOOL – DIY-12-HP-115B25 DIY (Highest 12,000 BTU Mini Split With Highest SEER Rating)

110V voltage can generate quite a lot of BTU output. 110V BTU, together with about 10-15 amps, can generate up to 15,000 BTU in window air conditioners.

The most popular mini-splits can reach a maximum of 12,000 BTU running on 110V. The portable air conditioners also get a decent cooling capacity; the largest at 110 is 14,000 BTU.
