best portable air conditioner guide that shows the top best air conditioner model

A whopping 75% of electronic and appliance reviews are untrustworthy. That’s why every reviewer gets a Trust Rating so our True Score System filters out the fake reviews. See how we do it.

It can be frustrating to install window AC units. You have to move these heavy models and lift them in place every year. They also block your window view. That’s why many choose portable air conditioners. Our buying guide focuses on models that offer efficient cooling, easy mobility, and energy efficiency. Out of over 22 air conditioners evaluated, we identify the three top air conditioners.

Our process involves analyzing 169,780 reviews and certifying tested units, with our proprietary and scientific True Score filtering out fake and low-quality reviews. The selected models impress in cooling speed, energy efficiency, and quiet operation, proving their value for your comfort and convenience.

    Our Verdict

    The Whynter ARC-1230WN is a highly efficient portable air conditioner boasting an energy efficiency ratio (EER) of 10.7. With a power draw of just 1.24 kWh, it’s rather efficient but still manages to cool quickly, lowering the temperature by one degree in just 5 minutes, so you don’t have to suffer in the summer.

    The air conditioner is also surprisingly quiet in operation, producing just 56.2 decibels, which puts it below the level of most conversations. The low noise level is highly welcome if you use an air conditioner for white noise or want one to be less obtrusive while running. The unit also features wireless connectivity, allowing you to control it through a mobile app, so you can crank up the cooling or lower it without leaving your couch or chair.

    Whynter’s ARC-1230WN is a versatile and energy-efficient portable air conditioner. Its low power draw, rapid cooling speed, and wireless connectivity make it a reliable choice for cooling just about anywhere you put it. If you’re seeking a portable air conditioner that balances performance, noise control, and energy efficiency, the Whynter ARC-1230WN is an excellent choice.

Which Criteria Matters for Testing Best Portable Air Conditioners?

By focusing on these criteria (3 nice to have), anyone can quickly and easily compare these air conditioners and how they’ll perform. This helps you make an informed decision and purchase an excellent portable air conditioner.

Operating Noise< 55 dBNo (Nice to have)How much noise the unit makes while it is under normal operation.
Cooling Speed< 5 min/degreeNo (Nice to have)How long it takes a unit to successfully lower the temperature in an area by one degree, measured in minutes.
Power Draw< 1 kWhNo (Nice to have)How much power the unit draws while under normal operation, measured in kilowatt hours.

Our Trusted Data Sources

We looked at 60+ air conditioner reviewers and found that 15 are trustworthy (60%+ Trust Rating). The three we have listed below are our most trusted for air conditioners.

  1. Austin Palmer – TechGearLab, MuckRack
  2. Daniel Jackson – Your Best Digs
  3. Derek Hales – Modern Castle, LinkedIn

Interested in a comprehensive analysis of our data sources? We’ve got you covered. Below, you’ll find a detailed list of every air conditioner review website we’ve identified, organized by their respective Trust Ratings from highest to lowest. But we didn’t stop there. We’ve meticulously reviewed each publication and verified the data by checking whether the authors have bio links to MuckRack or LinkedIn. We’re committed to not only checking the facts but ensuring their veracity.

Air Conditioner Test Data & Results

1. Operating Noise (dB)

All air conditioners make noise, this is a fact. Generally speaking, the more airflow an A/C unit has, the louder it’s going to be, and (logically) the more capable it is of cooling larger spaces (or smaller spaces more quickly.) Quieter A/C units are less disruptive and are often more attractive if you like a more peaceful home, but if your cooling needs are very high, be ready to see higher noise levels.

It’s for this reason we recommend an operating noise level around 55 dB or less. This puts it below the noise of a typical conversation and allows the sound to fade away into being background noise or even white noise. Higher volumes can be distracting, especially if you’re very sensitive to droningsounds.

Operating Noise (dB; lower is better; 0 = No Data)

2. Cooling Speed (Min/Deg)

There are multiple factors that influence how quickly an air conditioning unit is going to cool down a space. The size of the A/C, if it’s in good condition or not, the size of the room, and the actual settings chosen (for example, using a quiet mode or a performance mode.)

We recommend a cooling speed of at least 5 minutes per degree lowered, but faster cooling speeds are always welcome. It’s important to note that this is for when you use the A/C unit in a room that it’s designed for. If you stick a very small A/C in a huge room, the cooling speed is going to be abysmal, and if you put an oversized unit in a closet, you’ll be putting up some impressive numbers, but neither are realistic.

Cooling Speed (Min/Deg; lower is better; 0 = No Data)

3. Power Draw (kWh)

The size of your A/C unit is often the biggest determining factor behind how much power it draws – bigger units with bigger mtors draw more power. But units that are the same size might not be built the same, and the power draw they exhibit can vary wildly in some cases, even when they’re on roughly the same settings.

We generally recommend a power draw of less than 1 kWh, but lower is better – provided it doesn’t impact your unit’s ability to cool. Some units (especially larger ones) will require more power no matter what though, especially if they have larger motors or claim to push more CFM and actually deliver on that claim.

Power Draw (kWh; lower is better; 0 = No Data)

Best Portable Air Conditioners: Mistakes To Avoid

  1. Neglecting Room Size: Underestimating the size of the room can result in an underperforming air conditioner, while overestimating can mean spending more than necessary. Measure your room’s dimensions and compare them to the manufacturer’s recommendations to ensure proper cooling capacity.

  2. Overlooking Ventilation Requirements: Not planning for proper ventilation can render your portable air conditioner ineffective. These units need to expel hot air outside, so ensure you have a window or another suitable venting option available. If a window is not an option, learning how to vent a portable air conditioner without a window is crucial. Consider alternatives such as venting through a sliding door, ceiling, or wall to maintain the unit’s efficiency. Proper ventilation ensures that your portable air conditioner can effectively cool your space.

  3. Forgetting About Energy Efficiency: Ignoring the energy efficiency rating of a portable air conditioner can lead to higher electricity bills. Look for units with a high EER (Energy Efficiency Ratio) to save money over time and reduce environmental impact.

  4. Not Checking Noise Levels: Overlooking the noise level of a portable air conditioner can lead to a disruptive environment. Check the decibel (dB) rating to ensure the noise level is acceptable for your space, especially if it will be used in a bedroom or office.
