How to Choose a Split System AC Unit

Posted on: 26 October 2015

You may have been attracted by the lack of complicated ducting systems when one installs a split system AC, and you may now want to buy a spilt system for your home. This article discusses three important factors that you should consider as you select a split system air conditioning system.

Conditioning Zones

Conditioning zones refer to the number of areas that you wish to heat, or cool. Buy a single zone system if you wish to cool only one area/room. Such a system will have only one indoor component (air handler/evaporator) and one outdoor component (condenser). Buy a multiple zone system if you need to condition the air in several rooms. Such a system will have several indoor units for each outdoor unit. The number of indoor units varies from one manufacturer to another.


BTUs or British Standard Units are a measure of the power of an air conditioning system. One of the most important aspects that you need to consider is the total area you need to cool so that you pick a split system AC that will have the capacity to cool that area. Each indoor unit and each outdoor unit has a given BTU rating. The combination of indoor and outdoor units should match the total area that you wish to cool. Talk to an HVAC technician so that he or she can help you to assess the BTU rating that will deliver satisfactory results without using a lot of energy.

Installation Mechanism

This boils down to what you prefer as an individual and the conditions existing in your home. Some split system indoor units require to be mounted on a wall. Others can be mounted on the ceiling while others can be placed on the floor. Each installation system has its pros and cons so pick the one that meets your needs. For instance, wall-mounted split systems are easy to access for routine maintenance but they may disrupt the uniformity of your interior décor if their colour clashes with your colour theme. Ceiling-mounted units may be unobtrusive but it may be difficult to access them when routine maintenance work needs to be done.

It will be easier for you to identify the best split system air conditioner if you use the factors above as a guide to narrow down your options from the multitudes available on the market. It may also be advisable to request a certified HVAC technician, such as those at ACSIS Airconditioning Warehouse, to install the system so that you get the best of what it has to offer.
