Mitsubishi Starmex air conditioners are some of the best on the market. They are energy efficient and provide cool, refreshing air during the summer months. However, like all other appliances, they require regular maintenance in order to function properly and last long. Here are some of the most common mistakes people make when maintaining their Mitsubishi Starmex aircon unit.

Not Having Regular Maintenance Performed

When it comes to maintaining your Mitsubishi Starmex air conditioner, there are a few things you should avoid if you want to keep it running smoothly. One of the most important things is to have regular maintenance performed. This means having an aircon service provider come out and check on your unit at least once a year. They’ll be able to clean it, make sure the Freon levels are good, and look for any other potential problems. Not having this done can lead to big problems down the road, so it’s definitely something you want to avoid.

Leaving their aircond on all the time

Another mistake people make is thinking they can just leave their unit on all the time. While it’s true that Mitsubishis are designed to run for long periods of time, they still need a break every now and then. If you’re leaving your house for an extended period of time, be sure to shut off your air conditioner so it can take a break. Otherwise, you risk damaging it and shorten its lifespan.

While it may seem like a good idea to keep the aircond running 24/7, it can actually lead to a number of problems, including decreased efficiency, increased energy costs, and condenser damage. Instead of leaving your aircond on all the time, only turn it on when you need it. Not only will this save you money, but it’ll also help extend the lifespan of your unit. Plus, you can always set a timer so it’ll turn off after an extended period.

Ignoring weird sounds

If you’ve ever experienced a weird noise coming from your Mitsubishi Starmex aircon, you know it can be pretty unsettling. After all, your aircond is supposed to be whisper-quiet, right? Unfortunately, strange noises are often one of the first signs that something is wrong with your aircond. So, if you’re hearing strange sounds coming from your unit, it’s important to take action quickly. The longer you wait, the more likely it is that the problem will get worse and lead to costly repairs.

One of the most common causes of strange noises in airconds is loose parts. Over time, vibration from the unit can cause screws and bolts to loosen. If left unchecked, these loose parts can eventually cause damage to the compressor or fan motor. In some cases, they can even cause the unit to catch fire. So, if you hear rattling or banging coming from your aircon, be sure to check for any loose parts and tighten them up right away.

Another common cause of strange noises is worn-out bearings. The compressor and fan motor in your aircond both have bearings that help them run smoothly. However, over time, these bearings can wear down and become damaged. When this happens, they can cause a lot of noise. If you hear a grinding or squealing noise coming from your aircond, it’s likely that the bearings need to be replaced.

Not Replacing Outdated Aircond Parts

At some point, every Mitsubishi Starmex aircon will need to be repaired or replaced. However, many people make the mistake of not replacing outdated parts, which can lead to more expensive repairs down the road. Over time, aircond parts can wear out and break down, reducing the efficiency of the unit and resulting in higher energy bills.

These outdated parts can also cause the unit to overheat and break down completely. As a result, it’s important to regularly check the condition of your aircon and replace any parts that are no longer working properly. By taking this proactive approach, you can avoid costly repairs and keep your aircon running smoothly for years to come.

Not Checking Air Filters

One of the most common mistakes people make when maintaining their Mitsubishi Starmex aircon is not checking the air filters. Over time, these filters can become clogged with dust and debris, reducing the efficiency of your aircond. Furthermore, if the filters are not replaced on a regular basis, they can cause permanent damage to the unit. As such, it is important to check the air filters monthly and replace them as necessary.

Another mistake that people often make is neglecting to clean the coils. The coils are responsible for cooling the air, so it is important to keep them free of dirt and grime. To clean the coils, simply remove them from the unit and rinse them with warm water. You can also use a brush to remove any stubborn dirt and debris. Once the coils are clean, be sure to dry them completely before putting them back in the aircon.

Failing to Maintain proper humidity levels

Another common mistake people make is failing to maintain proper humidity levels. If the air in your home is too dry, it can cause a number of problems, such as static electricity, dry skin, and respiratory issues. On the other hand, if the air is too humid, it can lead to mold and mildew growth. As such, it is important to maintain a healthy balance of humidity in your home.

The best way to do this is to invest in a humidifier or dehumidifier. These devices can help you maintain proper humidity levels, which will in turn help you avoid a number of problems.


Mitsubishi Starmex aircons are a great investment for any home. However, like all appliances, they require regular maintenance to keep them running smoothly. By avoiding the common mistakes outlined above, you can ensure that your aircon lasts for years to come.
