Buying guide for best Honeywell portable air conditioners

Last Updated December 2019

If you don’t have central air conditioning, there are probably areas of your home that get pretty warm in hot weather. A portable air conditioner can help cool off a room, and you can move it around your home as your cooling needs change. What’s more, a portable air conditioner is easy to install and costs significantly less than a systemic HVAC upgrade.

Honeywell, a respected name in home heating and cooling, offers some of the best portable air conditioners on the market. Honeywell portable air conditioners are available in a variety of capacities to cool rooms of various sizes. Some models also offer a dehumidifier mode to help remove excess moisture from the air.

Because Honeywell offers quite a few portable air conditioner models, choosing the right one can be challenging. You have to decide which drainage type you prefer, what size space you want to cool, and what other features you require. With our shopping guide, you’ll have all the information you need to find the best Honeywell portable air conditioner for your home. We’ve also included some specific product recommendations to make shopping as simple as can be.

When you’re using your Honeywell portable AC in air conditioning or dehumidifying mode, keep your windows and doors closed. If you’re using it in fan mode, opening a window or door can help improve the air circulation.

Key considerations

Drainage type

Because a portable air conditioner draws moisture from the air, water collects inside the appliance and needs to be drained. Honeywell portable air conditioners offer three main types of drainage:

  • Self-evaporative portable air conditioners exhaust the water back into the air. Some models are fully self-evaporative, so they never have to be emptied manually. Other models are partially self-evaporative, but you will sometimes need to remove water from these units, particularly on hot and humid days.
  • Gravity-drain portable air conditioners allow you to drain the water through a hose that’s connected to a floor drain. The water drains continuously, and gravity does all the work.
  • Manual portable air conditioners feature a water collection bucket that holds all of the water that the air conditioner removes from the air. You empty the bucket every few hours.

Powerful and versatile

You really get your money’s worth with the Honeywell MM Series Air Conditioner. Not only does it offer 14,000 Btu to cool up to 550 square feet, but it also has a heating feature that sets it apart from most other portable ACs. This AC is self-evaporative, which means you need never manually empty a bucket to keep it working.

Capacity

Cooling capacity is usually the most important factor to consider when choosing a Honeywell portable air conditioner — or any air conditioner, for that matter. You want a model that’s big enough to cool effectively but not so large that it wastes energy. Air conditioning capacity is measured in British Thermal Units (Btu) per hour. The larger the space you want to cool, the more Btu you need.

In general, you can use these guidelines to determine how powerful your portable air conditioner should be:

  • 8,000 Btu can effectively cool rooms that are 200 square feet in size and smaller.
  • 10,000 Btu can effectively cool rooms that are 300 to 400 square feet in size.
  • 12,000 Btu can effectively cool rooms that are 400 to 450 square feet in size.
  • 13,000 Btu can effectively cool rooms that are 450 to 500 square feet in size.
  • 14,000 Btu can effectively cool rooms that are 500 to 600 square feet in size.
     

Honeywell portable air conditioners range in power from 8,000 to 14,000 Btu, so you choose the model that fits your cooling needs.

EXPERT TIP

For the best performance, make sure to clean the exterior of your portable air conditioner every month. Wipe it down with a damp cloth to remove any dirt, dust, or debris.

Features

Digital display

Some high-end Honeywell portable air conditioners feature a digital display, which makes operating the AC a breeze. This feature allows you to easily see the air conditioner’s settings and quickly change them when necessary.

Fan speeds

Nearly all Honeywell portable air conditioners offer multiple fan speeds, so you can choose the best speed for your needs. A higher setting can help circulate the air more effectively, especially on hotter days. Honeywell portable air conditioners typically offer three speed options.

Dehumidifier function

Most Honeywell portable air conditioners can also operate solely as a dehumidifier. When the weather is cooler, the unit simply removes moisture from the air without cooling the room. Keep in mind that you will need to connect the unit to a drainage hose or empty it manually when it’s functioning in dehumidifier mode.

Timer

Many Honeywell portable air conditioners have a programmable timer function. That means you can set your AC to turn on shortly before you leave work, so your home is cool when you get there. It can also help you save energy by turning the AC off at a specific time.

Remote control

Most Honeywell portable air conditioners include a remote control, so you’re able to operate the appliance from across the room. You can usually turn the AC unit on and off, adjust the temperature setting, and change fan speeds without having to leave the couch.

Honeywell doesn’t recommend using an extension cord with its portable air conditioners.

Honeywell portable air conditioner prices

Honeywell air conditioners vary in price based on how large an area they can cool and how many special features they offer. Prices range from $250 to $700.

The most affordable Honeywell air conditioners are those that offer less than 10,000 Btu and don’t have many special features. You’ll typically pay between $250 and $325 for models in this category.

Mid-range Honeywell air conditioners will provide between 10,000 and 12,000 Btu of cooling power. They often have some special features, such as a digital display and remote control. They usually cost between $325 and $560.

The most expensive Honeywell portable AC units will offer 12,000 to 14,000 Btu of power. They have plenty of special features, including a digital display, a remote control, and a timer function. You’ll usually pay between $560 and $700 for these high-end models.

EXPERT TIP

Honeywell recommends that you clean your portable air conditioner’s air filter every two to three weeks to keep it working efficiently.

Tips

●     Avoid placing your portable air conditioner in a sunny area of your home. The heat from the sun will force the AC unit to work harder to cool your room.

●     Don’t place your portable air conditioner flush with a wall. Instead, make sure there’s some space between the wall and the appliance so air can flow. Your owner’s manual should have a recommendation for how much space to leave between the two.

●     Make sure that your portable air conditioner’s exhaust hose is as straight as possible. Kinks in the hose could limit the airflow and discourage ventilation.

Affordable but still powerful

The Honeywell MN10CESWW is a budget-friendly model. But the lower price doesn’t mean the AC skimps on power — it offers 10,000 Btu, which can cool up to 450 square feet of space. The user-friendly digital controls and remote make operation simple.

Other products we considered

Honeywell offers a fairly wide range of portable air conditioners, so we didn’t have room for all of the models worth checking out on our shortlist. The Honeywell 10,000 Btu Portable Air Conditioner is a decent option for small to midsize rooms. It has a digital display, three fan speeds, and a 24-hour digital timer that can help save energy. We love the Honeywell 14,000 Btu Portable Air Conditioner/Heater for larger rooms. Not only can it cool and dehumidify up to 700 square feet, but it also boasts a heating feature that allows you to use the appliance year-round.

If you plan to place your portable AC in storage at the end of the summer, make sure to drain all the water from it before putting it away.
