The 3 Best Most Affordable Portable ACs

When the summer heat hits its peak, we all yearn for an oasis of cool. Central AC units, while effective, might not always fit everyone’s budget or setup. Hence, the rising popularity of portable air conditioning units—a convenient and affordable solution. As we sifted through the multitude available in 2021, we’ve narrowed down the list to three standout units that offer the best value.

However, if portable units aren’t exactly what you’re looking for, don’t fret! Perhaps window air conditioners or ceiling fans might be more up your alley. But for now, let’s dive into our top portable AC picks.

Why Portable ACs?

Portable AC units are not only mobile, allowing you to move them between rooms, but they also require minimal setup. Ideal for renters or those with space constraints, they provide flexibility that static units don’t. Plus, their energy-efficient models ensure a reduced impact on the monthly electricity bill.

Finding the Right Size for Your Portable AC

One common oversight when purchasing a portable AC is choosing the wrong size. Contrary to what some might think, bigger isn’t always better. The size of the unit you’ll need depends on the size of the room you aim to cool.

First, measure the room’s square footage. For a square or rectangular room, multiply the room’s length by its width. For irregularly shaped rooms, it might help to divide them into smaller sections, calculate the square footage for each, and then add them together.

Once you have your room’s square footage, you can generally follow this guide:

  • Up to 200 sq. ft.: Choose a unit with 8,000 BTUs (British Thermal Units).
  • 200 to 300 sq. ft.: Opt for a unit with 10,000 BTUs.
  • 300 to 400 sq. ft.: You’ll want a unit with 12,000 BTUs.

However, consider other factors too. If the room has high ceilings, and large windows, or receives a lot of sunlight, you might need a unit with higher BTUs. Similarly, if you’re cooling a kitchen, the heat from appliances might necessitate a more powerful unit.

Lastly, remember that an oversized AC might cool the room quickly, but it won’t efficiently remove humidity, leaving the room cold and clammy. On the other hand, an undersized AC will need to work overtime, leading to excessive wear and higher electricity bills.
