Split Air Conditioner Buyer's Guide
Written by Ryanne BrownIntroduction
A split air conditioner is a type of air conditioning unit that is composed of two parts, an indoor unit and an outdoor unit. The indoor unit is installed in the room that needs to be cooled, and the outdoor unit is installed outside the building. Split air conditioners are a popular choice for those looking to cool their homes or businesses, as they are quieter, more efficient, and easier to install than traditional window units. When looking to buy a split air conditioner, there are several important things to consider, such as size, energy efficiency, noise level, and cost.
Size
The size of the split air conditioner you need to purchase depends on the size of the room you plan to cool. Generally, the bigger the room, the higher the BTU (British Thermal Unit) rating of the air conditioner will need to be. As a general rule of thumb, you should look for an air conditioner with a BTU rating that is at least 20 BTUs per square foot of the room. Additionally, you should also consider the number of people in the room, as this will also affect the size of air conditioner you need.
Energy Efficiency
When looking for a split air conditioner, it is important to consider the energy efficiency of the unit. Look for an air conditioner with an energy efficiency rating (EER) of at least 10, as this indicates that the unit is relatively energy efficient. Additionally, you should also consider the SEER rating of the unit, which measures the efficiency of the unit over a longer period of time. Higher SEER ratings generally indicate a more efficient unit.
Noise Level
Another important factor to consider when purchasing a split air conditioner is the noise level of the unit. Most air conditioners are relatively quiet, but some can be quite loud. If you are looking for a quieter unit, look for one with a noise level of less than 50dB. Additionally, you should also look for units with features such as noise reduction technology and adjustable fan speeds, which can help reduce the overall noise level of the unit.
Types of Split Air Conditioner
Split air conditioners come in several different types, including window units, wall units, and ductless mini-splits. Window units are the most common type of split air conditioner and are typically installed in windows or other openings. Wall units are installed directly into the wall and are generally more energy efficient than window units. Ductless mini-splits are the most energy efficient type of split air conditioner, as they are installed directly into the wall and do not require ductwork or vents.
Cost
The cost of a split air conditioner will vary depending on the size, type, and features of the unit. Generally, smaller units are more affordable than larger units, and ductless mini-splits are usually more expensive than window or wall units. Additionally, units with higher energy efficiency ratings, more features, and quieter operation will generally be more expensive than units with lower ratings, fewer features, and louder operation.
