Due to their energy efficiency and flexibility, mini-split HVAC systems have grown in popularity over the last several years. The many advantages mini-split systems have compared to traditional HVAC systems already make them a great choice. However, curious homeowners may still be concerned about the system’s lifespan. The good news is that when well maintained, a ductless system can last 5-10 years longer than a traditional heating and cooling system. Here, we will explore how long mini-split HVAC systems last and the different factors that can affect that lifespan.
Mini-Split HVAC Explained
With traditional HVAC systems, you will typically have a large outdoor unit and a single indoor unit. After the air is warmed or cooled, it is blown through the ductwork and out of the vents in each room of your home.
Mini-split systems are designed differently. With a ductless system, you still have one outdoor unit. However, instead of ductwork, refrigerant lines go from your outdoor unit to different parts of the home and are connected to interior units. These indoor air handlers are each responsible for blowing air and controlling the temperature.
Factors Affecting Mini-Split HVAC Lifespan
Ductless mini-split systems can last anywhere from 15 to 20 years and sometimes many years past that. Your traditional central system usually lasts only 10 to 15 years. There isn’t an exact amount of time that a ductless mini-split will last because so many different factors are involved. Being aware of these factors can help you make good decisions to ensure your mini-split system has a long lifespan.
Installation Quality
The installation quality is another factor that can affect your mini-split HVAC system’s lifespan. A poor installation can result in loose components, bad electrical wiring, and more that will cause problems later on and reduce your system lifespan. If you hire a company with little to no experience working with ductless mini-split HVAC systems, the chance they can make a mistake during installation is higher. Additionally, you want skilled HVAC technicians from a reputable company to ensure they won’t cut corners or overlook critical steps during the installation process.
Number of Units
A sufficient number of indoor units is required to properly control the temperature within your home. Not having enough units in your home can mean that the limited units you have will be working harder to cover a larger area. Again, this puts unnecessary stress on system components, lowering lifespan over time. At a minimum, mini-split HVAC systems usually have a unit in each bedroom and a unit in the main living space. If you have a larger home with large areas and more rooms, more units may be required to sufficiently warm or cool your home.
Mini-Split Placement
In addition to the sizing and number of interior units for a mini-split system, placement can also play a part in the HVAC system’s lifespan. Interior units need to be placed for optimal airflow and circulation in each room or area. This includes ensuring furniture or other home decor items aren’t obstructing airflow. If units are mounted in a way that airflow is minimized, it can cause homeowners to change the temperature settings to compensate for it, adding stress to your system.
Usage Frequency
How often you need to run your system will affect its lifespan, similar to putting miles on a car in a shorter timeframe. If the home is empty most of the day and your HVAC system is off, your system can last longer. However, if you work from home or there is always a need to run your mini-split HVAC system day and night, it can reduce its lifespan due to added usage.
Temperature Preferences
Temperature preferences can be a lifespan factor. For example, if you prefer to keep your home much colder than the average person during a hot summer, your system will work harder, and more stress will be put on components. However, the stress on interior units will be based on the preferences of the people who occupy that room the most. So, some units may last longer than others within the same home. To ensure a longer lifespan, choose a moderate temperature setting.
Scheduled Maintenance
Your HVAC system needs regular professional maintenance to function optimally. Technicians can tighten any loose components, lubricate moving parts, and find any other issues that could affect the system’s lifespan. Regular professional maintenance significantly impacts the longevity of your system.
Home Insulation
If your home doesn’t have sufficient insulation, your HVAC system will have to work harder to compensate for it. Anytime your HVAC system is required to work harder to keep your home comfortable, your system lifespan can be reduced.
