Know Before You Buy: The Top 5 Concerns of Ductless Mini Split Systems
Any good thing will always have drawbacks…and a ductless mini split system is no exception.
Let’s look at some of the concerns that consumers have raised in the past so you can decide if a mini split air conditioning system is, ultimately, the best choice for you.
Concern #1: Aesthetically Less Appealing
One of the biggest complaints many people have about installing a ductless air conditioning system into their homes is that they find the indoor units to be unattractive (and are even considered an eyesore by some!)
Here’s why:
- Indoor Unit Visibility: In some installations, the indoor units are visible on the walls or ceilings of rooms. Their presence can disrupt the aesthetics of a well-designed interior, especially in spaces where a sleek, minimalist look is desired.
- Bulkier Indoor Units: While mini splits are generally compact, certain models may have larger indoor units, which could be considered less aesthetically pleasing, especially if they cannot be discreetly integrated into the room’s design.
- Refrigerant Lines and Wires: The refrigerant lines and electrical wiring connecting the indoor and outdoor units may be visible in some installations, which can detract from the overall appearance of the space.
- Color and Design: Mini splits typically come in neutral colors like white, which may not blend seamlessly with all interior color schemes or design aesthetics. This lack of customization options can be a drawback for some homeowners.
- Preference for Central Air: Some individuals simply prefer the look of traditional central air systems, which are often hidden from view and have a more familiar and conventional appearance.
It’s worth noting that manufacturers are continually working to improve the aesthetics of mini split systems by offering different styles and designs for indoor units, as well as more discreet installation options.
Additionally, for those who prioritize aesthetics, consulting with or hiring a professional installer may help plan the placement of indoor units, and conceal wiring and lines can help mitigate these concerns.
Concern #2: Sizing and Capacity
Selecting the correct size and capacity of a mini split system is crucial for optimal performance and comfort. Mini split systems comes in many different sizes and tonnages including the popular 2 or 3 ton mini split single zone systems but ranging from half ton all the way up to 5 ton systems.
A system that is too small will struggle to adequately heat or cool the space, resulting in inefficiency and discomfort.
Conversely, an oversized system may cycle on and off frequently, failing to remove humidity effectively and causing temperature fluctuations.
Improper sizing can lead to:
- Inefficiency: An undersized system will work continuously to reach the desired temperature, increasing energy consumption and potentially reducing the system’s lifespan. Conversely, an oversized system may frequently start and stop, wasting energy.
- Discomfort: A system that is too small may struggle to maintain the desired temperature, leaving occupants feeling too hot or too cold. On the other hand, an oversized system may result in uneven heating or cooling, leading to discomfort and temperature variations within the space.
To address this concern, it’s essential to consult with HVAC professionals who can perform load calculations to determine the appropriate system size and capacity for your specific space.
Factors like room size, insulation, climate, and desired temperature levels all play a role in sizing decisions. By investing in a properly sized system, you can ensure efficient operation, consistent comfort, and long-term cost savings.
Concern #3: Installation Challenges
The installation of HVAC mini split systems can be both a selling point and a concern for homeowners.
On one hand, these systems are often praised for their relative ease of installation compared to traditional ducted systems. However, several factors can still pose challenges and emphasize the importance of proper installation.
Ease of Installation: Mini split systems are typically easier to install than ducted systems because they don’t require extensive ductwork. This can save on installation time and costs. Additionally, the ability to place the indoor units strategically can provide flexibility.
Installation Concerns: Despite their simplicity, mini splits must be installed correctly to ensure optimal performance. Issues such as improper placement of indoor units, refrigerant line installation, or electrical connections can lead to inefficiencies, cooling or heating imbalances, or even system malfunctions.
Proper Installation Significance: Proper installation is crucial for achieving the energy efficiency and comfort mini split systems promise. A well-placed indoor unit maximizes airflow and temperature distribution, ensuring that each zone is adequately heated or cooled. Careful attention to refrigerant line insulation and electrical connections also prevents leaks, reduces energy loss, and maintains indoor air quality.
Concern #4: Maintenance and Servicing
Proper maintenance and servicing are vital aspects of owning a mini split system to ensure it continues to run efficiently and provide reliable heating and cooling.
Homeowners should be aware of the importance of regular upkeep and understand their responsibilities in this regard:
- Efficiency and Longevity: Routine maintenance is the key to keeping a mini split system operating at its peak efficiency. It involves tasks such as cleaning or replacing filters, inspecting and tightening electrical connections, and ensuring that the indoor and outdoor units are free from debris and obstructions.
Neglecting maintenance can result in decreased efficiency, higher energy bills, and a shortened system lifespan. - Basic Maintenance Tasks: Homeowners can contribute to the longevity and efficiency of their mini split systems by performing basic maintenance tasks.
These include regularly cleaning or replacing air filters, clearing away any debris or vegetation around the outdoor unit, and checking for visible damage or loose connections. These simple steps help prevent common issues and ensure the system operates smoothly. - Professional Servicing: While basic maintenance tasks can be handled by homeowners, it’s advisable to consider scheduling professional servicing at least once a year.
Trained technicians can perform more in-depth maintenance, such as cleaning the evaporator and condenser coils, checking refrigerant levels, and ensuring the entire system is functioning optimally. This professional servicing not only extends the system’s lifespan but also addresses potential issues before they become costly repairs.
Concern #5: The Drainage System
The drainage system for mini splits has also been known to be a frustrating concern at times.
Like all heating and cooling systems, mini splits produce condensation as they cool the hot summer air in your home. This condensation accumulates in the indoor unit and travels through a pipe to the outside of your home.
Finding a good endpoint for the condensation is where things get tricky. Unless you want to construct an extensive piping system, the condensation typically ends up next to the outdoor unit, which means it can end up pooling outside your home, near your foundation. You’ll want to think carefully about where you want the condensation from your indoor air handling unit to end up.
Another area where water build-up has been known to be problematic is inside the indoor unit. Depending on how the drainage system gets set up and how the mini split gets installed, there’s a chance for an indoor pipe to clog or kink.
A clogged or kink drainage pipe means that condensation will gather inside the indoor unit and eventually overflow since it’s unable to travel to the outside.
Again, many of these issues can be avoided or quickly rectified with a good installation process and help from a reputable HVAC expert.
