Average Mini Split Lifespan

LG mini splits are an ideal long-term heating and cooling solution because with adequate care, they can last 20 years or more. That’s long enough for parents to buy a home, have children, and raise their kids to adulthood, all with the same reliable system. However, the longevity of your equipment can be impacted positively or negatively depending on how well you take care of it.

Having your heat pump serviced seasonally and fixing any issues that arise as quickly as possible mean that your system will be more likely to last beyond the 20-year mark. But only having an HVAC consultant come out when there’s a problem ensures that untreated wear and tear on your system will shorten its overall lifespan. It’s tough to know how much time neglecting the maintenance of a ductless system will shave off, but it’s better not to find out.

Why Do Heat Pumps Last So Long?


There are numerous reasons why heat pumps – and LG mini splits in particular – last as long as they do, like:

  • Avoiding high static pressure. Static pressure is your heat pump’s resistance to airflow, which can happen with an improperly sized system, environmental changes, and other factors. High static pressure can put extra wear and tear on your system, making it work much harder to heat or cool your space.
  • Avoiding hard starts. A “hard start” is when an HVAC system turns from off to on and the compressor has difficulty turning or staying on. Inverter technology allows mini splits to “soft start,” which means the compressor and motor slowly gain power. Because this process is much less energy intensive than traditional systems, it causes less stress on the equipment and its internal components over time.

How to Properly Maintain Your LG Mini Split

Taking good care of your LG ductless system is critical to ensuring that it reaches its full potential. Here are some helpful maintenance tips you can start using now to help keep your mini split in great condition:

  • Have your system routinely checked by an HVAC professional. This ensures that any potential problems that are starting to develop are caught and mitigated early before they have a chance to get worse or cause damage to other parts of your equipment.
  • Keep your air filters clean. Dirty filters block airflow coming through your heat pump, which causes it to work harder to push treated air out and into your space. Ductless filters are easy to access and easy to rinse or wash off, so you can do this regularly to improve your indoor air quality.
  • Clean the evaporator coils. The heat exchange process inherently produces condensation, which collects as droplets of water on your unit’s evaporator coils. If left alone, this water breeds bacteria and mold, causing an unpleasant odor to develop and even potentially resulting in health problems.
  • Don’t let your outdoor unit get dirty. It’s just as important to keep your outdoor unit clean as it is your indoor unit, since this is where heat is either extracted or released depending on which mode you’re using. Try to clear away leaves, snow, dirt, and any other debris away from your unit regularly or as soon as they appear.
