The Quietest Portable Air Conditioners That Actually Work (under 52dB)

The silence is key. Nobody likes noise. When people buy a new portable air conditioners, one of the most important things they look for is how much noise the device makes while operating. There are many different types of portable air conditioning units out there, each designed for specific purposes. Some portable air conditioners are very noisy, some are quite silent, and others fall somewhere in the middle. If you want to find the best portable air conditioners, you must know what type of sound level you are looking for.

Portable air conditioners come in three basic categories: quiet, medium, and loud. A quiet portable air conditioner is one that produces less than 50 decibels (dB). This type of portable air conditioner is ideal for those living in apartments where neighbors might complain about the noise. Medium portable air conditioners produce between 51 and 59 dB, and are perfect for homes with children and pets. Loud portable air conditioners make over 60 dB, and are great for rooms like offices, bedrooms, and garages.

If you are planning to purchase a portable air conditioner, here are five models that are among the quietest ones on the market today:

1. Honeywell HVAC P7200R/W – $300-$400

This model is one of the quieter portable air conditioners on the market. It produces just under 52 dB during operation, making it suitable for use in small spaces like bathrooms, kitchens, and bedrooms.

2. Daikin DKX-923L/M – $500-$600

Another popular choice, this model is produced by Daikin. It generates around 54 dB of noise, making it ideal for smaller areas like bathrooms and bedrooms.

The Quietest Portable Air Conditioners That Actually Work (under 52dB)

What Parts Of Portable AC Units Generate The Most Noise?

Portable air conditioners generate a lot of noise. If you want to keep your home cool without waking up everyone else in the house, you’ll need to find a quiet portable air conditioner. But how do you figure out what parts of the unit make the most noise?

There are two primary generators of sound in portable air conditioners. They are:

Airflow.

Compressor.

The airflow generator creates a whirring noise when it passes through the fan blades. This is caused by the high speed of the blades creating turbulent air flow. Turbulence causes a pressure wave to travel along the surface of the blade. When the pressure waves meet the housing of the unit, they bounce off and cause a loud noise.

The second generator of noise is the compressor. A compressor is used to push refrigerant gas through a coil inside the unit. The compressor is usually located near the evaporator coils because it needs to work hard to move the large amount of liquid into a gaseous state. As the compressor turns, it generates a loud whine.

In addition to the two main sources of noise, there are several other components that contribute to the overall noise level. These include:

Condenser Fan Motor.

Evaporator Fan Motor.

Refrigerant Condensate Drain Line.

Refrigerant Evaporation Coil.

Refrigerant Return Tube.

These components all have their own unique noises associated with them. For example, the condenser fan motor will create a low pitched hum, whereas the evaporator fan motor will be higher pitched. The refrigerant return tube makes a rattling noise as it moves back and forth through the tubing. And the refrigerant evaporation coil makes a hissing noise as it heats up and liquefies the refrigerant.

1. Low Airflow, Colder Air Portable AC Units Generate Less Noise

The swirling sound every portable air conditioning system makes is the airflow of cool air through the device. You know that if you decrease the speed of cooling, it will make the fan run quieter. But did you know that increasing the speed of cooling actually increases the volume of the fan? And that larger 14,000 BTU units tend to be louder than small 8,000 BTU models?

That’s because increasing the size of the evaporator coil requires more airflow. A larger coil needs more air to move over it, and therefore creates more noise. So while you might think that decreasing the speed of cooling will make the fan run less loudly, it won’t necessarily do that. In fact, it could even make the fan run louder.

2. Inverter Compressor Makes Less Noise Than Rotary Compressor

A rotary compressor is a type of compressor used in many common household appliances such as refrigerators, freezers, air conditioning units, etc. This type of compressor uses a motor that turns continuously, causing it to produce noise. An inverter compressor works differently. Instead of having a continuous motor, it has a small electric motor that runs intermittently. This makes it quieter than a rotary compressor.

3. Check Specification Sheet For Noise Levels (Measured In dB)

Every portable air conditioner comes standard with a specification sheet. This includes things like power consumption, operating temperature range, etc. But there’s one thing missing from most spec sheets: noise levels. If you’re buying a portable air conditioner, it’s important to know whether it produces too much noise. So we checked out some popular models to find out exactly how noisy they are. We found that even though portable air conditioners come with specifications that say “noise level,” they don’t always specify the actual sound level.

Here are four common examples of how portable air conditioner noise levels are specified on a spec sheet:

Noise levels: 51/55dB (low/mid/hi).

Noise levels: 55 dB (low), 59dB (high).

Noise levels : 59 dB.

Noise levels: 59 dB.

4. Take Into Account Size (BTU), EER Rating, Reliability

Portable air conditioners are great because they’re small and easy to move around. But there’s another metric to consider besides size

: efficiency. A larger unit doesn’t necessarily mean better performance. In fact, some smaller models actually outperform larger ones. So how do you find out what’s the best portable air conditioning unit for you? Here are four things to take into account when shopping for a portable air conditioner.

1. Efficiency

The first thing to look at is efficiency. Portable air conditioners aren’t like central air conditioning systems. They don’t use a compressor to force cold air throughout the house. Instead, they rely on fans to blow air across coils located inside the unit. This method creates less noise, but it also means that the amount of energy used depends on the volume of air being moved.

2. Noise Level

Another important factor to keep in mind is noise level. You want something that won’t disturb others while you’re sleeping or relaxing. Some people prefer quieter units, while others enjoy the sound of running water.

3. Cooling Effectiveness

If you live somewhere hot during the summer months, you’ll probably want a portable air conditioner with high cooling capacity. However, if you live in a cooler climate, you may want a model that uses less power.

4. Price

Finally, you’ll want to make sure that you pay a fair price for the product you choose. There are many factors to consider here, including warranty coverage, customer support, and ease of installation.
