Energy Efficient Portable Air Conditioner Buyer's Guide
Written by Ryanne BrownIntroduction
A portable air conditioner is an ideal solution for cooling a small to medium-sized room. It offers convenience and portability and is a great choice for those who do not have access to a central air conditioning system. However, there are a lot of things to consider when selecting an energy efficient portable air conditioner, such as size, energy efficiency, noise level, and features. This guide will help you identify the right portable air conditioner for your needs.
Types of Portable Air Conditioners
There are a few types of portable air conditioners available on the market. The most common type is a freestanding unit, which is designed to sit on the floor and can be moved around easily. It comes with wheels, making it even more convenient to move it around. Another type is a window unit, which is mounted on the window sill and usually comes with a kit that includes a window panel and an exhaust hose. Finally, a split system air conditioner uses two separate units, one inside and one outside, connected by an insulated tube. Split systems are more efficient than the other two types but require more installation.
Size
When selecting a portable air conditioner, it is important to consider the size of the room it will be used in. For example, a small room will require a smaller unit whereas a larger room will require a larger unit. It is also important to consider the BTU (British Thermal Unit) rating of the unit. Higher BTU ratings indicate a more powerful unit and one that is suitable for larger rooms. The size of the unit will also determine the noise level, with larger units usually operating more quietly.
Energy Efficiency
When selecting an energy efficient portable air conditioner, it is important to look for the Energy Star label. This label indicates that the unit meets energy efficiency standards and is certified to use less energy than conventional models. Additionally, you should check the energy efficiency ratio (EER) rating, which is the ratio of the cooling capacity of the unit to the power it consumes. The higher the EER rating, the more efficient the unit is.
Noise Level
Most portable air conditioners produce some noise while they are running. Look for units with a lower noise rating and make sure to read reviews to determine how loud it actually is. Additionally, larger units tend to run more quietly than smaller ones. It is also possible to buy separate noise reduction kits to reduce the noise levels further.
Features
The features of a portable air conditioner will vary depending on the model, but many come with additional features such as a timer, remote control, and air filter. Timers are useful for setting the unit to turn off after a certain amount of time. Remote controls are convenient for controlling the unit from a distance. Air filters can help to reduce allergens in the air and improve air quality. It is worth considering these features when selecting an energy efficient portable air conditioner.
