Split system air conditioners have several advantages, such as their simplicity and cost-effectiveness. However, they may develop problems due to several factors. This article discusses some of the reasons why your split system air conditioner may not perform as you expect it to.
Improper Remote Control Unit Installation
The split system air conditioner can exhibit several defects, such as excessive heating or cooling, in case the remote control unit was placed in an unsuitable location. Unsuitable locations don't allow the unit to receive heated or cooled air from the AC. Consequently, it will be unable to adjust the parameters of the system in response to the changing conditions within the space where the air conditioner is operating. It may therefore be necessary to relocate that remote control unit so that it can work better.
Wrong Fan Speed
The air circulation within the conditioned space may be insufficient to achieve the cooling or heating effect that you desire. This problem can be caused by an improper setting on the fan. For example, the fan speed could be set at the "LOW" level when the ambient conditions necessitate a higher fan speed in order to cool or heat the space effectively. Changing the fan speed setting to "HIGH" or "MEDIUM" is likely to fix the problem.
Extended Ducts
Split air conditioning systems usually utilise minimal lengths of ducts/tubes to connect the indoor units to the outdoor units. However, the circumstances at a given installation site may necessitate the use of longer ducts. For example, the outdoor unit may need to be hidden in a distant corner of front yard where it will not affect the aesthetics of the landscaping. That extended duct may prevent the air within the system from flowing at an appropriate rate. You can buy a booster cable from the supplier of your system. That cable will compensate for the pressure drop due to the longer duct.
Lack of Insulation
Your air conditioning system may not work effectively in case you didn't insulate the refrigerant ducts or tubes that connect the indoor units to the outdoor components. Consequently, the refrigerant may gain heat to the extent of affecting the functioning of the system. Insulate those tubes separately so that the heat from the heated refrigerant tube doesn't affect the temperature of the liquid refrigerant in the cold tubes. As you can see, many of the defects that happen in split system ACs can be traced to an installation issue. It is therefore advisable for you to let an expert to install the system correctly so that you avoid the malfunctions that can result from improper installation.
