Quietest Portable Air Conditioners – Top 4 Quiet AC Units

A lot of homes and businesses have centralized air conditioners these days that make little to no noise whatsoever inside. The units are tucked away outside, making noise that is virtually impossible to hear when going about life inside walls.

Unfortunately, other air conditioner options can’t sit outside. If a person purchases a portable air conditioner, it needs to stay inside at all times. This requires not only having space for it, but tolerating the sound that goes with everything operating.

Portable air conditioners come in many different shapes, sizes, and maximum power. These are different than air conditioner units that can go in the window, as these portable options generally sit on the floor. (source)

Here is a look at some of the best out there, and how the quietest portable air conditioners can help people live a better life overall.

1. Vremi Portable Air Conditioner

Vremi Portable Air Conditioner

As one of the best sellers online right now, this option from Vremi comes in ranges from 10,000 BTU all the way to 14,000 BTU. People can also purchase a machine that offers heat, making this a device worth the money for all seasons.

One of the first things a person should look at when investing in a portable air conditioner is power. If a machine is not going to be powerful enough, it is not worth wasting any time with. Sometimes, people get caught up about machines being quiet, and they forget that power matters quite a bit as well.

The machine operates right around 50 dB for the most part. The company spent a lot of time working on performance at a quiet level, and providing solid cooling capacity that never has many issues at all. This allows people to enjoy working from home, sleeping, and anything else that requires a quiet area.

It is easy to set up and allow for hands-free operation throughout the day as well. There are a total of three different fan speeds, and four operation modes to get the right set up for an individual home.

A programmable timer allows people to save money and energy by turning the unit on and off when it is not needed.

One of the biggest factors as to why this machine tops many lists is the fact that they offer a perfect way to handle humidity. The built-in dehumidifier operates by discharging any hot air outside through an exhaust hose. Since the unit does not have a built-in reservoir tank, it is very important to set this up for a more tolerable experience overall.

The energy-saving options are some of the best in the business, which helps out people who do not want to see their energy bills get too crazy.

If the unit needs to move around, this is one of the easiest portable solutions out there. It is a lightweight unit in the first place, but the wheels to move things around make it super simple.

One of the advantages of having a portable air conditioner is moving it to certain areas depending on what is needed. The problem is, too many options are way too heavy, and that leads to frustration.

All in all, Honeywell has a lot right with their portable air conditioner. It is a little more expensive than some of the other options out there, but that mostly comes from the price people pay for a well-known brand.

Black & Decker has a wide range of portable air conditioners to consider, and picking the right one is pretty easy going off charts. They start at 8000 BTU, and go all the way up to 14,000 BTU. They all are built to a high standard, and plenty of features are available for people to have maximum control over temperature.

As is the case with all of these options, the first thing anyone wants to know is just how loud these operate. Sound hovers at around 50 dB, and lower settings can allow a person to get even lower.

Black & Decker comes with one of the best warranties out there, so if anything does start to go wrong, they will fix it free of charge.

4. DeLonghi Portable Air Conditioner

For the ultimate quiet experience, this portable air conditioner might be the best of the best. It is a little more expensive than some people want to spend, and it might not come with all the features a person wants, but sound levels are a huge deal to them.

They have an Arctic Whisper Quiet mode that solidifies that thought, and even without using that mode, people will still really enjoy just how quiet things are.

How does Arctic Whisper Technology work? It understands what needs to be done to get a room to a specific temperature, and then start running at a lower capacity.

A person should not be wasting energy on something that does not need 100% power at all times anyway. It is a very smart process that keeps things very quiet, and people usually appreciate that.

It is a portable air conditioner, but also a dehumidifier that works very well too. Using the real fuel mode, a person can balance the temperature and humidity inside a room at all times. It is very easy to keep on track, either using the controls on the machine, or the remote control.

Portability is pretty solid overall, but not the best of the best. This is something that usually stays in one room for most people, although it does come with wheels to move it around. All the features added make it a little heavier than some people realize, which can be frustrating.

If quiet is what a person needs, this option is hard to beat. Some people who already own the machine will even say that they can’t hear anything when it is in use. It really starts to blend in with the rest of the ambient noise around a home or office, which is great news for light sleepers.

  • Built-in dehumidifier
  • Customization options are plentiful

Picking the Right BTU

With BTU mentioned quite a bit in the article, many people might have questions on what to do with that number. The basic rule is that an air conditioner needs 20 BTU for each square foot of living space that they need to cover.

That means, generally speaking, a 10,000 BTU machine is going to cover about 500 ft.². This obviously has a little bit of wiggle room, but it is a good starting point for people to make smart decisions.

If a person can afford it, it is always best to go with a slightly bigger option than what is needed. That is because a portable air conditioner might be moved to a bigger room, and it adds to some versatility. If a person is really worried about something being quiet, it also helps to have more BTU. That means it can run at a lower level, which usually limits how much sounds made.
