How Long Does a Ductless Air Conditioner System Last?


Every time we upgrade something in our home, we want it to last for as long as possible. Who wouldn’t? One of the major draws for ductless systems is that they can last longer than traditional forced air HVAC systems. But there are caveats.

You need ductless HVAC repair in Morton Grove, IL, but you want to know how long those repairs will last and how long your system will last. Let’s talk about what you can expect from your ductless HVAC system.

On Average, They Last for 10-15 Years

We know, that’s a wide time gap, but we did mention there were caveats. A ductless mini split system can traditionally handle up to four air handlers. The number of handlers you have can make a difference on performance.

If you only use one handler (which is completely okay), all the wear and tear will be on that unit. There’s no relief because you aren’t alternating between another handler in a different room. Your heating and cooling rely on this one air handler.

More air handlers mean less mechanical wear and tear on individual units, but that also means more units to maintain. Overall, your system can last for that 10-15 year timespan with proper care and not putting 100% of the load on a single air handler.

What Else Affects Ductless Air Conditioner Lifespan?

Ensuring proper maintenance and repairs is on you as the homeowner. That’s imperative to the longevity of your system, but it’s not the only force at play. These other factors impact your ductless system’s lifespan, and not all of them are within your control.

  • Improper Installation: The installation practice is as important as the system itself. Problems such as improper exhaust, the wrong refrigerant, and improperly-sized units can all impact how they run.
  • Coastal Areas: If your ductless system is near a coastal area, salty air can shorten its lifespan due to its corrosive properties. Thankfully, here in Morton Grove, IL, we have a very low-salt level in Lake Michigan, so this isn’t much of a worry.
  • Extended Runtime: Running any piece of machinery for longer than it should be can exacerbate wear and tear. Additionally, even though it should go without saying, you shouldn’t have the windows or doors open while running a ductless mini split system.
  • Bad Insulation: If your home isn’t insulated well, you’re spending extra money on heating and cooling. Beyond that, it takes longer for your ductless system to alter the temperature in your inefficient home, meaning it runs longer and produces more strain on the system than necessary.

Your Future With Ductless Mini Splits

With proper care, your ductless HVAC system should last anywhere from 10 to 15 years. There are separate mini splits with their own thermostats and usage, so it’s difficult to narrow that scope.

All you need to know is that if you upkeep annual maintenance and are conscious of how you use your ductless HVAC system, it can last for a long time.
