Portable air conditioners provide effective cooling to spaces without access to central air conditioning or areas that simply need supplemental cooling. They are a popular choice for their mobility and for cooling small spaces such as bedroom, offices, basements and computer rooms. The portable units are available in a wide range of cooling capacities and include various user-friendly features.
There are a many reasons why people may want to use a portable air conditioner. Sometimes older homes do not have duct work, or people who cannot afford to install a new central heating and cooling system in their house may have no choice but to have a portable air conditioner. Portable air conditioner units include air cleaners, fans and dehumidifiers. The improved quality of the air alone is often a reason to go with a portable air conditioner unit. Also, a portable air conditioner can be moved from room to room. And, the installation of the portable unit is easy. The units do require space for tubing to run through the wall.
The portable units have a single exhaust hose that routs air from inside the room over the air conditioners’ condenser coils and finally to the outside. A typical portable air conditioner comes with a low-profile vent adapter bracket that is placed in a double-hung window to allow the hot, humid air to escape. The air from the room that is being cooled is exhausted outside.
Pros of Portable Air conditioners
Central air conditioners energy use in a home or business costs homeowners cost more than $15 billion per year, according to the American Council for an Energy-Efficient Economy. Proper matching of portable air conditioners to the square footage of a room can help lower cooling costs when supplementing a central air conditioning system. This is especially true for rooms that generate more heat, such as a kitchen or an office with copiers, computers and other equipment. Let’s look at some of the pro features and their benefit to you.
Ability to cool small areas Can be moved from area to area as needed.
Economy Lower cooling costs than central air systems. Lower price for the equipment that the window model.
Minimal Set up Only requires a simple venting system with a hose and a window spacer.
Energy Use Uses less energy that a central air conditioner.
Emergencies Useful in an emergency when other systems have failed or an unusually hot period occurs.
Humidifiers Portable air conditioners are also dehumidifiers – meaning they cool the room and they remove excess moisture from the air.
Maintenance Low maintenance costs, mainly cost for changing filters.
Cons of Portable Air Conditioners
The main drawbacks of portable air conditioners are listed below.
Feature Con Issue
Energy rating Low rating; Many do meet or exceed the 10 SEER efficiency ratio
Cost Portables have to run a long time during hot spells.
Noise They are louder than other types of air conditioner systems.
Condensation Some models require a drip pan you must empty daily. A unit could produce 30 pints of condensation per day.
Area coverage Only useful for small areas.
