Pros and Cons of AC Mini-Split Systems
 
 
 
 

Ductless mini-split air conditioners provide the much needed cool air to hard-to cool/heat spaces. Unlike the conventional central air conditioner, which uses one large air handler to cool air, and then pushes the cool air to your rooms through ducts, mini-split systems are ductless. They cool each room individually using separate air handlers, which supply cool air directly to the rooms where they are mounted. These air conditioners have been gaining lots of traction in recent years and in this post, we outline the pros and cons of using AC mini-split systems.

Pros of Mini-Split Systems Energy Efficiency

Ductless mini-split systems, as the name suggests, do not have ducts. Therefore, you save around 25 percent energy that is normally wasted in the ducts. Most of these systems achieve a SEER within the 20 to 25 range. Unlike ducted systems that might lose a certain percentage of energy due to leaks, AC mini-split systems don’t have this problem. Furthermore, you only need to turn on the air handles in the rooms that you want to heat or cool.

Low Noise Levels

Ductless mini-split systems are designed to be used indoors. For this reason, they operate quietly (noise levels as low as 19dB). Plus, there are no large components in the unit that make noise with every temperature change.

Easy to Install

The best part about getting yourself a ductless mini-split system is that it's not labor-intensive compared to ducted systems. While you might still require a professional to do the installation, anyone with the right skills and tools can still get the job done with ease. You don’t have to tear up walls or part of the attic. AC mini-split systems are designed to be mounted on walls, placed on the floor, or flush with the ceiling. The units are also quite small, which means that they occupy less space, which can be ideal where space is limited.

Low Maintenance

With ductless mini-split systems, maintenance is fairly easy, not to mention low cost. While you can hire a company, you can also do it yourself. Remember, you're not dealing with lots of components like ducted systems. This also means that you have fewer components that need replacing.

They Come with Area Zoning

Some houses have areas that tend to be colder or warmer than others. AC mini-split systems allow you to adjust the temperatures in different rooms independently. For instance, if you want some cool air in your room while your kids don’t because they are asleep, all you need to do is set a warm temperature for their rooms and cool temperature in your room. You can find units offering up to four indoor air handlers connected to one outdoor unit. Since each zone has its own thermostat, you only need to turn it on when the space is occupied, cutting energy costs.

Versatility

Ductless mini-split systems are highly versatile and come in handy in scenarios where you have room additions or extensions like garages or basements. Likewise, the AC mini-split system is ideal if you have rooms that are far from the central air handler.

Provides Better Indoor Air Quality

Sometimes, the ducted systems trap dust and pet dander in the ducts, compromising the quality of air. However, ductless provide cleaner air and reduces the moisture, especially if you get a system with triple filtration.

Cons of AC Mini-Split Systems Expensive

The initial costs of a mini-split system are high, almost 30 percent higher than a traditional AC. You can expect costs to go even higher if you have several rooms that need to be installed with an air handler.

Visible

While ductless air handlers are small and designed for indoors, they might not be as inconspicuous as you would like them to be. Most of them are white plastics on your wall or ceiling, and they may not be aesthetically pleasing for your interior design. Fortunately, with time, you might get used to it and even forget that it exists.

Regular maintenance

Well, as we mentioned above, ductless have low-cost maintenance. However, they require regular cleaning and maintenance if you want them to give you longer service. Luckily, the process is simple, and every homeowner can do it. Just be sure to stick to a regular cleaning schedule since damages can be quite costly to repair.

Final Thoughts

AC mini-split systems are flexible, convenient, and easy to install. They are ideal options if you have multiple rooms that don’t have consistent temperatures since you can adjust the temperature individually.
