Quietest Dual Hose Portable Air Conditioner

If you’re not sure of what translates to an actual noise, try having a conversation close to a portable generator or a packed restaurant.

Thankfully, the invention of the quietest dual hose portable air conditioners has reduced noise to a distant memory, so you can freely enjoy your conversations. A portable air conditioner offers users efficient on-demand cooling for any indoor space. 

Most homeowners with central air conditioning may be used to the loud hum of an AC unit. But since the unit is placed outside, it doesn’t really matter if it is pretty loud.

Conversely, with portable air conditioners, the unit is entirely inside your home for your comfort. Most portable air conditioners generate noise that falls between 60 and 70dB, offer effective cooling, and are reasonably priced, especially useful for those with a tight budget. 

Below are the top models from recognized brands that make the least noise and trusted to keep your home cool and comfortable. 

Sizing a Portable Air Conditioner

The right-sized dual hose air conditioner ensures that your room is cool as it brings out the correct ambiance. Choosing an oversized unit does not remove all the moist air, while an undersized unit won’t adequately cool the room.

To get the right size of an air conditioner, you must first calculate the room area. Afterward, you’ll confirm if it resonates with the air conditioner’s British Thermal Units (BTU).

 The higher the BTU ratings, the larger the room it can cool. BTU unit is measured by the amount of heat an AC can remove from an environment. 

For instance, if your room is about 200 square feet in area, you’ll go for an 8,000 BTUs air conditioner. However, if your room is exposed to direct sunlight, or you need to place the AC in the kitchen, or the rooms that accommodate more than two people, then you’ll have to go for a higher ratings air conditioner.

Remember, to achieve efficient cooling operation; you must get the size right

Single Hose or Dual Hose

If you didn’t know, have it at the back of your mind that there are two different hose configurations for air conditioners-single hose and dual hose. 

A single-hose AC removes the warm air from the room by channeling it to the coils. The warm air and moisture are passed to the hose, which takes them outdoors.

The process creates a negative pressure as air is continuously driven out of the room. The pressure gap forces the hot air to find itself inside the room through cracks in doors and windows. 

A single-hose AC is appropriate for a smaller room as it has to work extra hard to cool a large room. Contrariwise, they operate quieter than a dual hose AC with the same BTU ratings. 

A dual-hose air conditioner has a couple of intakes but only one outtake. The intake point takes in the hot air, which is then cooled before driving it out. It also drives in cool air from outside to cool down the AC system. The purpose of the second hose is to drive the heated air outside the room. 

The dual nature of the intake and outtake eliminates negative pressure and allows the AC to operate smoothly, making it the better option. Besides, it cools the room 40% faster than the single hose AC.

On the contrary, dual hose ACs use internal fans/ condenser for cooling, making them operate loudly. They are also less portable and more expensive. 

Drainage System

Most portable ACs do not require a drainage system since they incorporate a self-evaporating system. The system recycles the condensed water back into the air.

It is viable in areas with low humidity; otherwise, you’ll have to dump excess water if the area experiences high humidity. The process requires you to manually empty the tank and release water if you see the light indicating that it is full. 

The portable units include a condensate pump that directs water into the tank and passes it outside through the hose. It depends on the AC you choose as some require extra installation to remove the water.

However, some operate automatically, thereby making the work easier. The manual draining system requires you to frequently empty the tank after two to six hours, depending on the room’s humidity. 

Energy Efficiency Ratio(EER)

Energy Efficient Ratio, customarily abbreviated as EER, is the unit used to measure how efficient an AC is in terms of saving energy. Ensure your AC has a higher EER (more than 10) as it will save you the extra costs of paying energy bills. 

Note that portable air conditioners get hot faster, but they are usually indoors, making the system work extra hard to push the hot air through the exhaust hose.

 Portable units also radiate heat inside the room they are located; therefore, they must work extremely hard to cool the room. Get a unit that is energy star certified to get classy efficiency. 

Additional features you can check on are remote control, heat/ AC combo, dehumidifier, and programmable thermostat.
