Portable Air Conditioner Noise

One of the biggest concerns people often have about getting a portable air conditioner is the noise levels they tend to create.

While this may have been true for older window air conditioners and portable air conditioners, newer models have incorporated various technologies to help reduce the noise levels produced by the unit itself.

While they will never be as quiet as your central air conditioner, quiet portable air conditioners are definitely able to find.

Why Were They So Noisy?

Older models of window and portable air units tended to create a lot of noise primarily because the fans installed within them were quite loud.

Because of their basic construction, not a lot of thought or effort was put into the volume of noise being created by the fans. Even older circulating fans tended to be noisier than newer models.

One huge noise reduction technique was to replace a large amount of the metal ‘guts’ of the fan, particularly the fan blades themselves, with durable plastic pieces.

This not only extended the lifespan of the blades, it also reduced the rattle that tended to be created with metal blades.

The best portable air conditioners for a home are also better insulated with regards to the casing they are housed in.

Because of this, the levels of noise that are still produced by the internal components of the unit are dampened significantly when they pass through the casing.

How Can I Reduce The Noise Levels?

Over the years, manufacturers have not only been able to reduce the noise levels created by the internal fans, they have also been able to add other features to assist in quieting the unit.

Since you may not always have the need to run the portable unit at full speed, most units now come equipped with variable fan speeds. The lower the speed you are running the unit at, the less noise the fan will produce.

This is perfect for running the unit at high speed during the day, when it is warmest outside, and then at low or medium speed at night, once the temperature has naturally cooled down.

Since the biggest complaint from consumers was the fact that it was difficult to sleep with the unit running at night, the ability to lower the speed of the fan, thereby lowering the noise, is extremely beneficial.

You can also try wrapping a blanket around the unit. This acts like a noise dampening material and can really help, especially in the bedroom at night.

While portable air conditioners may never be as quiet as central air conditioners, the advances in their design and construction over the years has dramatically reduced the noise levels they do output.

What To Look For?

Unlike standard window units, small portable air conditioners are only designed to cool rooms up to 350 square feet. This is accomplished with a unit rated for 12,000 BTUs, or British Thermal Units.

Smaller units can range from 7,500 BTU to 10,000 BTU, appropriate for rooms between 150 and 250 square feet.

While these numbers are fairly accurate, there are also a few exceptions that can effect which size unit you need to purchase. If a room is particularly shaded, you may be able to decrease the BTUs needed.

On the other hand, if the room is exposed to a great deal of direct sunlight or frequently occupied by more than one person, a higher BTU unit would be needed.

When shopping for a small portable air conditioner, there are several other factors to take into account aside from power.

For example, a unit on wheels or casters is ideal if you plan to move the unit from room to room on a regular basis. If you live in a humid area, you should look for a unit that can run its dehumidifier separate from the cooling operation.

Likewise, many units allow you to run the fan portion of the unit on its own, ideal for when you need to move air through a room but don’t necessarily need to have it cooled.

The more functions your small unit can handle, the more cost effective the unit becomes. But of course that also means more things can go wrong and that can make a noisier AC unit.
