Mini-split air conditioners are a blessing during the hot summer months. These units work round the clock to keep the environment in the house cool and comfortable for your family members to spend their time in. But it mini-split air conditioners tend to run into problems as well with bad odors being one of the most common. While your mini-split system may smell bad, there could be several reasons causing the issue and some may need you to call in an air conditioner repair service. Below are these reasons and how you can prevent them from taking place in the future.

Clogged Air Filter

If your ductless AC is smelling bad, one of the first things you need to do is check the air filter. Depending on the type, make, model, and variant, your mini-split system may contain more than one filter. Air filters are specifically designed to block contaminants and toxicants before air is circulated inside the house.

With time, these air filters tend to become clogged due to layers of dirt and dust accumulations. This not only poses the risk of toxic air being circulated inside the house but also forces the unit to work harder than usual to make up for the loss of air.

The air conditioner thinks there is some type of obstruction, which is causing the issue. As a result, it consumes more electricity and leads to hefty electricity bills. To prevent such an issue from taking place, you should regularly clean the air filters.

As a general rule of thumb, you should clean the filters at least once or twice every month depending on the usage.

Mold And Mildew

Both mold and mildew tend to be another reason mini-split systems tend to smell bad. Mold and mildew tend to take place in moist areas. This means if the air conditioner has not been used in a long time or there is a lot of humidity, your mini-split system will smell weird for a while.

This does not necessarily mean your system is at fault, sometimes, the external factors cause such issues. But a bigger problem associated with mold and mildew is that it can be dangerous for health. Since mold is airborne, it can cause health problems especially respiratory issues.

If your family members are constantly exposed to mold, it could lead to chronic breathing problems. The best way to avoid such problems is to maintain your air conditioner and get the unit professionally inspected as well, especially if it is being used after a gap.

Refrigerant Leaks

Refrigerant leaks are not that common in new units but can be an issue in older ones. Every air conditioning unit comes with a specific level of refrigerant that helps produce cool and warm air. If for some reason, the refrigerant tends to leak, it could cause the level to go down and put the compressor under extreme stress.

The compressor is completely reliant on the refrigerant to function properly. As the gas leaks, the compressors work harder than usual to compensate for the loss of cool or warm air, which not only consumes more electricity but also heats up.

If the problem remains ignored, the compressor will eventually give up and need to be replaced. The problem with refrigerant leaks is they are not prominent in the majority of the cases. This makes it difficult to spot the leakage source. But, if you come across a pungent smell, it might be that the refrigerant is leaking.

Check For Drain Clogs

Drain clogs can be a seriously irritating issue. Then again, it is mostly caused by a lack of maintenance of the air conditioner. The air conditioning unit releases water as a byproduct of the cooling process. This water makes its way out through drain clogs.

If the drain pipes happen to be clogged due to some reason, the water will not be able to escape and either accumulate or find some other areas to escape. With time, this may also create a bad smell as moisture builds up and mold starts to take place.

Unfortunately, homeowners tend to mostly ignore such minor factors that could play a crucial role in the smooth running of the unit.

Lack Of Maintenance

Sometimes, the problem does not lie with the unit but lack of maintenance. As mentioned in the beginning, mini-split AC systems like other household electronic appliances require care and regular maintenance.

While you might be able to check and clean the filters, professional maintenance goes deep inside the unit. There are a lot more components like the evaporator and condenser coils that need to be inspected and thoroughly cleaned to prevent dirt and dust accumulations from causing issues. If these components are not properly cleaned, they will not be able to dispense heat, which will raise the temperature and result in malfunction.

Keep in mind that both condenser and evaporator coils are expensive components, which means prevention is better than cure.

Burning Odor

Since mini-split air conditioners work continuously to keep the environment cool and comfortable during hot summer months, the motors tend to heat up, which can cause a burning odor as well. If you observe something as such, you should immediately shut down the unit instead of waiting for it to go away.

But keep in mind that the warm or burning smell that comes after turning on the air conditioner after a long gap is the smell of dust accumulation burning off. It should go away after a while but if it remains, it means the problem is something else.

Moreover, if you use your air conditioner regularly and you’re smelling a burning odor, then it can be due to overheating or an electrical issue. You should immediately turn off the unit and call in a professional who can inspect your AC.

How To Choose A Professional?

When it comes to choosing a professional to look after your mini-split AC, you will come across a huge number of options. While you may think it will make it easier for you to make a decision, do not be fooled.

Choosing a professional is one of the most difficult tasks as not everyone is equipped with the knowledge, skills, and experience required.

To be on the safe side, you should first ask around your friends and family members if they can refer someone. If not, you should research and look for some options in your area. Once you have multiple options, either call or visit their shop personally and interview them.

It is always best to choose a state-verified technician. Do not be tempted to opt for someone who offers a quote cheaper than the average market. Finally, cross-compare the options and pick the one that offers the best package.

In case of AC problems, you should not panic but be prepared to troubleshoot the issue head-on. The tips mentioned above will surely help you in such cases but you need to be observant and hire an AC repair service Smithtown if required.
