The Ultimate Guide to Split Air Conditioners

Split air conditioners are a popular choice for homeowners and business owners alike in Malaysia especially.

Split ACs have two separate units: an indoor unit that blows cool air into the room and an outdoor unit that houses the compressor and condenser.

This is just one of the many types of AC that are available.

Split air conditioners offer a range of benefits, including energy efficiency, noise reduction, and better air quality.

In this Ultimate Guide to Split Air Conditioners, we will explore the advantages and features of split ACs, as well as the installation process and maintenance requirements.

We have another post on how split AC actually works for further reading.


Benefits of Split Air Conditioners

Energy efficiency

Split air conditioners are more energy-efficient than window air conditioners because they don’t have to work as hard to cool the room.

The two separate units allow for more precise temperature control, which means the system can run at a lower capacity and use less energy.

Cost-effectiveness

Although split air conditioners are more expensive to install than window air conditioners, they can save you money in the long run.

Their energy efficiency means lower utility bills, and their longer lifespan means you won’t have to replace them as often.

Easy installation

Split air conditioners are relatively easy to install, especially compared to central air conditioning systems. You don’t need to install ductwork, and the outdoor unit can be placed up to 50 feet away from the indoor unit.

Noise reduction

Because the compressor and condenser are located outside, split air conditioners are quieter than window air conditioners. The indoor unit also operates at a lower decibel level than window units.

Better air quality

Split air conditioners have air filters that can remove dust, pollen, and other allergens from the air. This can improve indoor air quality and make the air healthier to breathe.


Features of Split Air Conditioners

Indoor unit

The indoor unit of a split air conditioner is typically mounted on the wall or ceiling. It blows cool air into the room and can be controlled by a remote or a wall-mounted thermostat.

Outdoor unit

The outdoor unit of a split air conditioner houses the compressor and condenser. It is usually placed on a concrete pad or mounted on a wall bracket.

Compressor

The compressor is the heart of the split air conditioning system. It compresses the refrigerant and circulates it through the system to cool the air.

Air filters

Split air conditioners have air filters that can remove dust, pollen, and other allergens from the air. These filters should be cleaned or replaced regularly to maintain optimal performance.

Remote control

Most split air conditioners come with a remote control that allows you to adjust the temperature, fan speed, and other settings from across the room.

Additional features

Some split air conditioners come with additional features, such as a dehumidifier to remove excess moisture from the air or a sleep mode that adjusts the temperature automatically at night.


Installation Process of Split Air Conditioners

We highly recommend that you leave this part to a professional like Acontech. While you can DIY if you really need to, here are certain things that you need to know if you are doing the AC installation on your own.

Preparation

Before installing a split air conditioner, you should gather all the necessary tools and materials, including a drill, screws, mounting brackets, and refrigerant lines.

Choosing the right location

The indoor unit should be mounted on a wall or ceiling where it can blow cool air into the room. The outdoor unit should be placed in a well-ventilated area away from direct sunlight and other heat sources.

Mounting the indoor unit

The indoor unit should be mounted securely on the wall or ceiling using mounting brackets. The unit should be level and at the correct height for optimal performance.

Installing the outdoor unit

The outdoor unit should be placed on a concrete pad or mounted on a wall bracket. The unit should be level and securely fastened to prevent vibration and noise.

Connecting the refrigerant lines

The refrigerant lines should be connected between the indoor and outdoor units. This should be done by a licensed HVAC technician to ensure proper installation and prevent leaks.

Electrical connections

The indoor and outdoor units should be connected to a power source. This should be done by a licensed electrician to ensure proper wiring and prevent electrical hazards.

Testing the system

Once the installation is complete, the system should be tested to ensure proper operation. The technician should check for leaks, adjust the refrigerant levels, and test the thermostat and remote control.


Maintenance of Split Air Conditioners

Cleaning the air filters

The air filters should be cleaned or replaced regularly to maintain optimal performance and improve indoor air quality.

Checking the refrigerant levels

The refrigerant levels should be checked regularly to ensure proper cooling and prevent leaks.

Inspecting the outdoor unit

The outdoor unit should be inspected regularly for signs of damage or wear and tear. Any debris or obstructions should be removed to ensure proper airflow.

Professional maintenance

Split air conditioners should be serviced by a licensed HVAC technician at least once a year. This can help prevent breakdowns, improve energy efficiency, and extend the lifespan of the system.


Conclusion

Split air conditioners offer a range of benefits, including energy efficiency, noise reduction, and better air quality.

Proper installation and maintenance are essential to ensure optimal performance and longevity.

Whether you’re a homeowner or business owner, a split air conditioner can provide cool air and comfort all year round.
