Extend the Lifespan of Your Mitsubishi Mini-Split AC

mitsubishi mini-split ac maintenance

Buying a Mitsubishi mini-split air conditioner is an excellent investment if you want to increase comfort within your home. Having control over your home or office temperatures isn’t always possible, but with the correct A/C installation and a properly working system, it is possible. However, like any other device, the Mitsubishi mini-split air conditioner also needs regular A/C maintenance. Learning how to expand the lifespan of your unit can be a jarring task but not an impossible one.

Here are some ideas you want to keep in mind:

Clean Your Mitsubishi Mini-Split AC Unit Often

The AC unit is one of those items with many protective systems to maintain its integrity and keep users safe. But even this product needs cleaning because it will accumulate dust, dirt, and grime. The simple fact that this Mitsubishi mini-split air conditioner has an outdoor unit means it’s exposed to the elements.

In this case, you should clean the debris, leaves, and dust from the unit. Clean the indoor unit too, and while there, you also want to clean the filters and replace any dust/pollen filters as needed. The AC has its manual that will give you all the tips and guidelines you need to understand the process better.

Power Off Your Mitsubishi Mini-Split Air Conditioner Sometimes

Many people need A/C repair services from time to time because AC units wear out faster if you run them constantly. So you can turn off the AC, especially if you want to leave your home for longer. Turning up the thermostat at night can also help. You want your unit to have a break, which will help you stop significant wear and tear in the long run. As long as you do that, you will be increasing your AC unit’s lifespan, which matters immensely.

Cleaning The Ducts

Aside from cleaning the AC unit as a whole, you also want to do some A/C maintenance for the ducts. That means you want to check and see if they are dirty since any debris or dirt accumulation might be why your ducts are not working correctly. When these ducts are stuck, cold air finds it hard to go through, which becomes a huge problem. You don’t have to clean the ducts too often; once a year is more than enough, even if you use the AC unit often.

Perform AC Maintenance

Tune-ups are a great way to increase the lifespan of your AC unit. A tune-up includes multiple tasks, like assessing the unit, cleaning it, inspecting all the components, and narrowing down any possible issues you might be facing. If you see any wear and tear on the components, you can repair or replace them.

That’s why A/C maintenance is essential; it will help you prevent many possible issues. That helps save a lot of money and the potential headache you get from figuring out what’s wrong and how to fix it.

Improve The Air Circulation Within Your Home

A good rule of thumb is to ensure that you have good airflow within your home. That’s why airflow is necessary when you perform A/C installation. We believe removing any obstructions in front of the unit is an excellent idea. If you remove obstructions, the Mitsubishi mini-split air conditioner won’t need to work as hard to circulate the air. That means you’re not wasting energy, and you’re also getting the target temperature you wanted all along.

Check Your Mitsubishi Mini-Split Air Conditioner For Leaks

Leaks are hard to identify, but they can be problematic. What you need to do is to assess the hose and see if you encounter any problems. If there are any leaks, that might be a sight that your unit either has a breakdown, or you need to replace the hose. Regular A/C maintenance will handle this since you will automatically identify leaks and slowly narrow down what causes them. It’s why maintaining your unit is how you will boost the lifespan of your item in the long run.

Changing The Filters

Typically, changing the filters is a part of regular A/C maintenance. However, you can also do it on your own if you want. The problem is that filters in your heating and cooling systems can get clogged due to dust, debris, and other reasons. If you change the filters often and clean them, you will boost the efficiency of your unit. What that also means is you’re saving money on energy costs. Plus, mini-split systems will work more efficiently when properly maintained. You’ll see the unit will last for a lot more time, and that alone can make a massive difference in the long term.

Work With A Professional Contractor

Whether you need A/C repair or maintenance, we highly recommend working with a qualified contractor. The reason is simple; you will have an expert making sure you have a team of experts handling any issues. Contractors have the knowledge, expertise, and equipment needed to tackle problems, which alone can be exceptional. We highly recommend working with an expert because you can identify issues and solve them fast while not damaging anything that might cost you lots of money to repair in the long term.

Use A Thermostat

The thermostat can be a great solution because you can pick the exact temperatures in your home. Check your AC unit’s manual and see which settings are great for saving energy. Then all you have to do is to apply them to the thermostat. Or, in some cases, you can experiment to see what settings fit your needs. Generally, the lower the temperature is, the more your unit will need to work. So all you have to do is to increase the desired temperature and go from there as needed.

Manage The Heat Load

The amount of temperature adjustment your unit has to do will automatically affect its lifespan. If you use a small air conditioner to cool a large home, the unit will need to go overboard and work more than it was designed to. Managing the heat load is extremely important, and it’s undoubtedly one of the things that will affect how much work your AC unit needs to do.

Contact The A/C Repair Technician If You See Any Issues

It’s a good idea to assess your A/C unit and narrow down what’s wrong with it. If you hear rattling or banging sounds, squealing, whistling, buzzing, or clicking sounds, those suggest a problem with your indoor or outdoor unit. It shouldn’t generate such sounds, so if that’s the case, you want to go directly to the A/C maintenance team for assistance. Whether you have a ductless mini-split, central air conditioner, or window air conditioner, Mitsubishi Electric is a reliable brand, and having the right HVAC technician can keep your unit running smoothly.


You can extend the lifespan of your air conditioner in many ways. It’s essential to constantly assess your unit and see if it generates any sounds. Also, preventative maintenance can go a long way because it delivers excellent results and tremendous value. It’s not going to be easy to ensure your air conditioner works perfectly in the long term, but adequate A/C installation and maintenance will help immensely.

We recommend using these tips if you want to ensure your unit will work perfectly for many years to come. Most A/C units can work for decades if properly maintained, so keep that in mind. Take good care of your air conditioner, which will help increase your comfort in the long run!
