Beginner’s Guide to Quiet Portable Air Conditioners

What Is a Quiet Portable Air Conditioner?

A quiet portable AC unit, like the Anbber portable air conditioner, is designed to operate at minimum noise levels. Most quiet portable AC units or even tower air conditioners are ventless, meaning they don’t require window or wall-vent installation with hoses to cycle indoor and outdoor air. Any AC unit designed with any major additional functionality, such as the best window air conditioners with heat, will be clearly categorized with that functionality by manufacturers, so finding low-noise models to choose from shouldn’t be difficult.

The advantages of such units are that they allow for self-contained operation and much more freedom of placement and mobility. You can use them to cool windowless spaces or locations where cutting a vent hole into the wall is impossible or impractical.

Small portable air conditioners are models built for quiet operation. They’re an especially good option for small mobile office spaces, recording studios, and seasonal workshops where excessive noise during use is either disruptive or highly undesirable. Their quiet operation also means they’re a good option for cooling small bedrooms that don’t often need air conditioning.

These types of units can vary greatly in terms of cooling capacity, filter type, fan speed, and additional features like auto-timer and sleep mode. Their energy efficiency can also vary quite a bit from model to model, but most work by cooling indoor air with water, instead of using a refrigerant cycling process like in conventional models. If you’re after the best portable air conditioner, you won’t have to worry about the appliance driving up your energy bills.

Quiet Portable Air Conditioners vs Other Models

Most window and wall air conditioners cool air using a refrigerant and indoor/outdoor airflow process combined with a compressor, condenser, and evaporator coil. Quiet portable air conditioning units are typically ventless. They feature a water tank that provides moisture which is then cooled on a cooling strip and blown into the room.

Another major difference between quiet portable units and conventional ones is that the ventless cooling of most such models doesn’t dehumidify indoor air, but actually humidifies it, since they cool air by adding moisture to it and sending it back into the room. Some such models include a dehumidifier mode in their extra features, but it’s fairly unusual and usually comes at a less affordable price.

Portable quiet units built for quiet running, such as the popular Electriq 12000 BTU quiet portable air conditioner, are designed to address another difference between portable and conventional models. While portable models, especially ones that are ventless, are generally quieter in terms of decibel levels than conventional models, the fact that they’re free-standing, take up floor space, and are usually closer to people in the room means that they’re actually louder.

Lastly, the quietest portable air conditioners, and portable models in general are less energy-efficient and slower to cool a space than conventional models, though this can vary depending on a specific model’s EER rating and Energy Star Status.

How Quiet Portable Air Conditioners Work

If you’re wondering how portable air conditioners work, quiet portable air conditioners generally work significantly differently than window AC, wall-installed air conditioners, or top-rated central air conditioning systems, since most function with a ventless “evaporator cooler” design that doesn’t require access to the outside air via a window or exhaust hose.

A ventless air conditioner is usually on caster wheels for mobility and has an open tank at the bottom that contains a refillable water reservoir, connected to a fan and a specialized cooling pad above. The fan draws in warm indoor air while a pump sends water to the cooling pad from the reservoir. Then the fan blows the indoor door air across the cooling pad where it picks up the moisture from the reservoir. This cooled air is then blown back into the room, cooling the room to the ideal temperature while increasing room humidity. Now if the AC is not blowing cold air, something’s clearly wrong with the unit and will require some self-troubleshooting or professional help.

Why Should You Buy A Quiet Portable Air Conditioner?

The reasons any portable option would be a good fit for you also apply to any quiet portable AC unit, with the additional qualification that a low sound level is a priority for you.

If you’ve got a windowless space, such as a workshop, temporary office, or basement, that you need to cool and cutting a vent hole for a wall installation is either impossible or impractical, a quiet portable AC unit will do the job well. This is especially true if it doesn’t need to run constantly throughout the year. If you eventually find yourself relocating to a colder climate and you don’t find the need to run your AC at all, but you need some heat, you can always learn how to replace your AC with a heat pump instead.

If you’ve got a small to medium-sized windowless space that only occasionally needs cooling and quiet operation is a priority, quiet portable units are again a good option. Keep in mind that the larger a portable unit is, the less efficient it is. So, a 700-square-foot room that would require an AC unit in the 15,000 BTU class might be worth attempting a wall installation (if it’s windowless) since the energy costs of a portable model in that BTU class would be high unless you used it very minimally. A quiet portable unit could be great for small spaces you only use occasionally like an RV, which the best portable air conditioner for an RV can be a great fit for.

Is a Quiet Portable Air Conditioner Worth Buying?

  • You have a small windowless workspace that needs to be quiet: If you have a small windowless workspace where noise would disrupt work, a quiet portable unit will do the job.
  • You have a small bedroom or nursery to cool: If you’ve got a baby room or bedroom to keep cool, especially if it doesn’t need regular cooling, a quiet portable AC designed to run quietly is a good pick.
  • You have several quiet spaces that only occasionally need cooling: If you’ve got more than one quiet space that needs only sometimes cooling or need a versatile backup cooling option for your home, quiet portable units are a good option.

Why a Quiet Portable Air Conditioner May Not Be For You:

  • You’re sensitive to humidity: Since most quiet portable units are ventless models that use evaporation cooling, most of your options here will noticeably raise humidity levels in a room, especially over long periods of use. While there generally isn’t a dry mode on such models, some include a dehumidifier mode. If you need to cool a room in an efficient amount of time but still want some portability, there’s always the best dual hose portable AC unit.
  • You’re cooling a large windowless space with a limited budget: If your budget is tight and you need to cool a windowless space with square footage over 700′, be aware that portable units, including quiet-running models, in the 15,000 BTU and higher class can come with a big price tag and low efficiency, meaning a bigger power bill. In this case, it might be worth looking into a wall-installed unit, which will offer superior performance at a better value.
  • Energy efficiency is your primary concern: Quiet portable AC units are far less energy-efficient than window air conditioners, regardless of their EER rating and Energy Star status, which also means a bigger carbon footprint. If you need a portable model for both cooling and heating like the best portable air conditioner and heater, keep in mind the amount of energy it would need to operate.

How Long will a Quiet Portable Air Conditioner Last?

Portable air conditioners are less efficient than window models and thus usually have a shorter lifespan- less than ten years with regular use. This includes quiet running units.

Several factors affect a unit’s lifespan:

Frequent Moving

Portable units are usually less sturdily built than their window and wall counterparts. If you’re using one in multiple spaces and moving it frequently, rattling parts and increased wear and tear can shorten the overall lifespan.

Heavy Regular Use

Sustained periods of heavy use increase wear and tear on a unit. Moreover, the humidity that great ventless portable A/C units create while cooling rooms can also take a toll on various components. Both of these factors can shorten life spans significantly. Consider investing in a unit with various modes you can set that can stay on top of reducing how much AC you need when you don’t actually need it, such as the convenient air conditioner auto mode on many units.

How to Choose a Quiet Portable Air Conditioner

Now that you’ve decided to purchase a quiet portable air conditioner unit, consider a few additional factors and features that will help you choose the right model for you.

Best Quiet Portable Air Conditioner Key Factors

1. How big a space do you need to cool?

Like in conventional models, portable air conditioners’ cooling capacity or cooling power is measured using British Thermal Units (or BTUs). Since they’re less efficient than stationary models, and high-BTU portable units are more expensive than comparable window or wall units, consider whether a portable unit is a practical use of your budget if your space is larger than 700 square feet. Cutting a venting hole for a wall unit may be the more affordable option, despite the installation process, and you’ll get more effective cooling performance, making it the more efficient option.

2. Do you prioritize energy efficiency?

Like window air conditioners, portable (and quiet portable) ACs measure energy efficiency with ratings created and enforced by the EPA and the U.S. Department of Energy. These will tell you how models within the same BTU class differ in terms of efficiency:

  • Energy Efficiency Ratio: A unit’s EER rating indicates BTUs per watt of power used. A higher rating means higher efficiency. For quiet portable models, the U.S. Department of Energy recommends an EER rating of 8.0 or higher. Ratings differ on even the leading energy-efficient window air conditioners.
  • Energy Star Certified: An Energy Star sticker or emblem on an appliance indicates it’s guaranteed to use a minimum of 10% less energy than comparable products. Most U.S. states also offer rebates on Energy Star products.

3. What’s your room used for?

Portable air conditioners designed for quiet operation tend to be a bit more expensive than comparable models and can be less efficient, so it’s worth thinking about how much quiet operation really matters to you if you’ve got a strict budget. While a baby’s room or bedroom is somewhere you might need an ultra-quiet air conditioner, other spaces, especially larger ones, don’t necessarily need one, especially if they face noisy areas, like streets or schools.

Best Quiet Portable Air Conditioner FAQs

What's the standard noise level in decibels for a portable air conditioner?

The approximate decibel range of portable air conditioners available on the market is 36 to 83 dB, depending on the model, with an average of around 70 decibels.

How many decibels do the quietest portable air conditioners produce?

A quiet or "silent" portable air conditioner is generally classified as one with a noise level below 55 decibels, which is around the level of the hum of a refrigerator. A unit's decibel rating is usually easy to find either on the unit itself or the manufacturer's website.

Do portable air conditioners need to be drained?

For the most part, no. Most portable air conditioners are ventless, meaning they use the water in their tanks to cool the air by adding moisture to it. While their tank needs to be regularly refilled, it doesn't need to be drained unless it's being cleaned.

Are portable air conditioners quieter than window devices?

It can vary quite a bit, depending on the quality of the respective models, the BTU class, and other factors, but one mitigating factor is that, even if a portable unit has a lower noise level, the fact that it's usually placed closer towards the center of the room means the noise they make is projected more.
