10 Best Portable Air Conditioners for Cooling Your Home

Portable air conditioners can be as effective as window AC units and can serve as permanent cooling solutions. They offer advantages over window units, such as versatility in placement and no need for permanent installation.

However, improper installation and sealing of the venting system are common issues with portable air conditioners, not their cooling potential. Jesse Mastro, owner of RentAnAC, recommends choosing a slightly higher BTU rating than you would for a traditional window AC to compensate for their slightly lower efficiency.

When purchasing a portable air conditioner, consider investing in a higher-priced model as they often provide better performance, although there are exceptions to this rule.

We have selected the top 10 portable air conditioners after testing 20 options on the market.

How to Choose the Best Portable Air Conditioners

Here’s how to pick the right portable air conditioner:

1. Measure Your Space: Start by measuring the room you want to cool. Consider ventilation and drainage options.

2. BTU Rating: Check the BTU (British Thermal Units) rating of the air conditioner. Aim for 20 BTUs per square foot of space. For example:

   • 150 to 300 sq. ft.: 7,000 to 10,000 BTU
   • 300 to 700 sq. ft.: 11,000 to 14,000 BTU
   • 700 sq. ft. or more: 14,000 BTU

3. Cooling Power: Pay attention to the BTU rating based on the DOE (U.S. Department of Energy) standard, as it’s more consumer-friendly and practical.

4. Noise Level: Consider the decibel rating for noise. Most portable ACs produce 50-60 decibels, but some quieter models exist.

5. Energy Efficiency: Look for energy-efficient models to save on electric bills. Check the EnergyGuide label for annual kilowatt usage estimates.

6. Smart Features: While not necessary, smart functions like scheduling and remote control can be convenient. Ensure you have Wi-Fi and a compatible device.

7. Maintenance: Be prepared to empty the condensate tank periodically. The frequency depends on humidity and tank size. Use plastic tubing or a bucket for draining.

By following these steps, you can find the ideal portable air conditioner for your needs while keeping your space cool and energy-efficient.

How Portable Air Conditioners Work

Portable air conditioners work by taking in hot, humid air and passing it over a cold coil containing refrigerant gas. This cools the air, which is then released into the room, lowering its temperature. At the same time, moisture in the air condenses on the cold coil and is collected in a pan for disposal.

The refrigerant gas, now heated, is sent to a compressor where it changes from a gas to a liquid. A fan blows over the hot coil, releasing the heat energy outside.

The condensed water can be disposed of in various ways, including manual removal, expulsion in the exhaust, or pumping it outside or to a drain.

Some portable ACs have one hose, while others have two. One-hose models use indoor air to cool the condenser and expel heated air outside. Two-hose models use outdoor air for cooling, maintaining indoor air pressure better.

The choice between single and dual-hose models depends on your specific needs. Single-hose models may create a slight pressure drop indoors, while dual-hose models maintain indoor pressure but have two hoses in the room.

What Are BTUs?

BTU stands for British Thermal Unit. It measures cooling strength by quantifying how much heat is removed from the air. Higher BTU ratings indicate greater cooling power.

You might encounter BTU ASHRAE and BTU DOE. BTU ASHRAE is the unit’s output, while BTU DOE factors in cooling loss through the hose and ventilation system, indicating how cool it may feel.

What Size Portable AC Do You Need?

When figuring out what size portable AC to get, focus on the BTU rating for your room’s size. Avoid buying a larger AC unit for a small space, as it can lead to unnecessary power expenses.

Consult the Energy Star square footage chart for BTUs based on room size to ensure energy efficiency.

Does Noise Level Matter for Portable ACs?

Portable ACs are a bit louder than window units as they don’t vent noise outside. To gauge noise, look for the decibel (dB) rating. Most portable ACs are around 56 dB on the highest setting, with slight variations in noise levels.

Is A Dual Hose Portable Air Conditioner Better Than A Single Hose Model?

A dual hose portable air conditioner is better if you have an older home or drafts. Single hose models can bring in hot air through leaks. Dual hose models have a dedicated outside air supply hose, avoiding this issue.

Do Portable Air Conditioners Work Better Than Window Units?

Portable air conditioners are convenient and easy to use, but window units are more powerful at cooling and cost less. Portable units can be moved around the house, while window units are fixed to one room. Consider these factors when choosing what’s best for your home.

How Much Does A Portable Air Conditioner Cost?

Portable air conditioner prices vary from $100 to over $1,000. A good quality one costs around $300 to $400, like the Serene Life SLPAC10. Larger cooling capacity models are more expensive due to enhanced cooling power.

Why do portable ACs have two Btu numbers?

Portable ACs have two BTU numbers because of different testing standards. The DOE BTU rating is more accurate as it considers hot air infiltration and heat losses through ducts. ASHRAE and manufacturer’s BTU don’t account for heat released back into the room by the exhaust hose and lack consistent testing standards. We rely on DOE ratings for accuracy.

What can you do if you are stuck with an AC that doesn’t have enough Btu to adequately cool a room?

If your AC doesn’t cool your room enough, follow these tips:

1. Keep the filter clean.
2. Close curtains and blinds during the day to reduce heat.
3. Use a fan to circulate cool air.

Can I use a portable air conditioner in a room without windows?

Yes, you can use a portable AC in a room without windows, but it needs an opening for the ventilating hose to send the hot air outside.

How do I clean and maintain my portable air conditioner?

To maintain your portable AC:

• Clean the filter monthly, more if used frequently.
• Check and clean the evaporator and condenser coils yearly.
• Inspect and clean the water pan and drainage system.
• Ensure the exhaust hose is clear and unobstructed.
• Store it properly when not in use to prevent dust buildup.
