Single-Hose vs. Dual-Hose Air Conditioners

Single-Hose vs. Dual-Hose Air Conditioners

With the advancements in air conditioning technology, the portable air conditioner (PAC) came into fruition. This is fast gaining in popularity, people are tired of bulking A/C’s awkwardly installed on their windows.

PACs or spot coolers save window space for the sunlight to come in and it will not disrupt the view from the outside. These units do not require a permanent installation, they have caster wheels for mobility, lightweight, and 28” to 34” high.

The hoses discharge warm air and moisture via the window and held in place with adjustable frames. Exhaust hose lengths vary by model and range from 4 to 7 feet. The material used is temperature-resistant plastic fortified with metal.

If you are in the market for a PAC there are two types to choose from, single-hose and dual hose.

Single-hose air conditioner

A no-brainer, it has one hose. The single-hose air conditioner yanks warm air and moisture from the room and expels it outside through the exhaust. A negative pressure is created when the air is pushed out of the room, the air needs to be replaced. In turn, any opening in the house like doors, windows, and cracks will draw outside hot air into the room to replace the missing air. The air is cooled by the unit and ejected in the room.Single-Hose vs. Dual-Hose Air Conditioners

The PAC can be moved to a certain area in the house that needs to be cooled. If the area is big, the unit will have to work hard to provide cool air, which can degrade the system and require an air conditioning repair. If it is in a room with computers or a mini-fridge consider a more powerful unit. Balancing air is very important, it can also be done by HVAC zoning.

Dual-hose air conditioner

The dual-hose air conditioning unit has two hoses, one functions as an exhaust hose and the other as an intake hose that will draw outside hot air.

The air is cooled and expelled into the area. This process heats the machine, to cool it down the intake hose sucks outside hot air to cool the compressor and condenser units. The exhaust hose discard warmed air outside of the house.

The design overcomes the negative pressure problem to achieve impressive efficiency.

Benefits of Portable Air Conditioners

Beat the heat with a portable air conditioner. A favorite among cool seekers, in recent years the demand for this equipment soared because of its convenience, versatility, and cost-efficiency.

Here are the benefits of owning a PAC:

  • The price of a portable air conditioner is lower than the window type air conditioner.
  • You don’t need to pay for the services of a technician. Just look for an exit for the exhaust and you’re good to go.
  • Roll your PAC to any part of the house which needs cooling, it is lightweight and easy to carry.
  • Unlike the central air conditioner, a PAC will only cool the place that you wish. It is smaller with a low operating cost.
  • Aside from cooling it dehumidifies the air. Fret not, if you suffer from an allergy the PAC will eliminate the allergens like mold and dust. There are PAC models with a “de-humidify only” feature that will remove the moisture from the area without cooling.
  • Some PACs have built-in heaters so you can enjoy the functionality the whole year. Others have high-efficiency filters to clean the air.

The single-hose portable air conditioner has to work extra hard to replace the expelled air reducing its overall efficiency. More unfiltered air enters the unit and shortens the length at which the filter removes allergens from the air ejected in the room. Indoor air quality is very important. But, it consumes less energy meaning a lower power consumption and the unit cost is cheaper which will suit people on a tight budget.

The dual-hose portable air conditioner can cool more space quickly. The design resolves the negative pressure problem and offers better cooling performance.Single-Hose vs. Dual-Hose Air Conditioners


The single-hose portable air conditioner fits people with a small space to cool and/or a lean budget.

The high efficiency of a dual-hose system is suitable for cooling large areas. But, comfort and efficiency come with a price, it will require more electricity and the cash outlay is higher.

A PAC goes beyond cooling, there are models that serve as a heater, a dehumidifier, an air purifier, and a fan.

Only you can decide which portable air conditioning unit will fit your needs since both units can provide you the comforts of cool air.
