5 Pros of a Wall-Mounted Split System AC

  1. Space Efficiency

Limited floor space? Smaller home? A wall-mounted split system AC can free up valuable space while still keeping you cool and comfortable. Compared to bulky traditional HVAC systems, a wall mount AC unit can maintain usable living space in a smaller home or room. Many modern wall mount AC units also feature sleek, modern designs that blend in rather than detract from a room’s appeal. 


  1. Ease of Installation

One of the biggest advantages of a wall-mounted split system AC is the straightforward installation process. Unlike traditional HVAC setups that entail complex ductwork and costly installation, split system installation is quick and easy. With no ductwork required and minimal components, a wall-mounted split system AC can be set up cheaper and faster than ducted HVAC systems. Often, just a small hole drilled in the wall is all that is needed to connect the outdoor and indoor units. If you have a home without existing ductwork or do not want to alter your home’s structure, a wall-mounted split system AC can save you hassle, time, and money.

  1. Cost-Efficiency

A wall-mount AC unit is a cost-effective option due to the lower initial investment and efficient operation costs. Without ducts, split system AC units are also less likely to lose air through gaps or leaks, making them even more efficient and cheaper to operate.

  1. Modern Conveniences

Along with being sleeker and more refined than bulky, awkward wall units of the past, modern wall mount AC units offer convenient features. Many modern split system AC units are also surprisingly quiet even during operation.  Split system AC units offer user-friendly options, such as: 

  • Remote controls to easily adjust settings such as the fan speed or temperature
  • Programmable settings, timers, sleep modes, etc.
  • Efficiency modes to conserve energy and cut operating costs
  • Built-in zoning that allows users to customise the temperature for different rooms or areas of the home

  1. Versatile and Easy to Customise

Since a wall mount AC is independent of other units, the system can be controlled separately. This makes wall mount AC units versatile and convenient. I often recommend split system AC units to homeowners who want to improve their current HVAC system without an expensive upgrade. Adding a wall mount AC unit in a room or certain area of the house can increase cooling capacity without investing in an entirely new system or undergoing extensive renovations.

  1. Possible Improvements in Air Quality 

Along with efficient, convenient temperature control, a split system AC can help support healthier air quality in your home. Many wall mount split systems help filter out allergens, dust, bacteria, mold, and other harmful particles. The simple setup also eliminates the chance of debris, dust, or allergens building up inside of ductwork and aggravating allergies or respiratory problems. These features help circulate healthier, cleaner air throughout your home.

3 Cons of a Wall-Mounted Split System AC

Here are 3 possible cons of a wall mounted split system AC unit to keep in mind. 


  1. Split System Installation Limitations

While the split system installation process is straightforward and faster since no ductwork is required, it presents possible challenges. The main challenge for split system installation is how much space is available. I consider how much wall space is open, how much open space will be around the unit, how close it is to an external wall, and other factors. In most cases, split system installation is possible but I have run into a few instances where there was not adequate wall space. 

  1. Access Considerations

Because there are no ducts to accumulate debris and dust, the overall maintenance for a wall mount AC is easier than a traditional ducted HVAC system. However, there are still challenges to consider when maintaining a wall mount AC unit. For instance, a unit mounted higher up on the wall may require a stool or ladder to access to change the filter or wipe down the surface of the unit.

  1. Cooling Limitations

A wall mounted split system AC unit is ideal for individual rooms, compact spaces, or smaller homes. If you have a larger home, you may need multiple wall mount AC units to achieve sufficient cooling. The initial cost of the units and the cost of operating multiple units  may not make sense compared to a traditional HVAC system. If you aren’t sure which AC system will be ideal for your budget, home, and needs, we can help you navigate the different options.
