In this blog post, we’ll touch on what could be going wrong with your system and when to call for a ductless mini split repair in Marion, IL.
Common Cooling Issues with Ductless Mini Split Systems
Ductless mini splits are great at keeping homes cool, but sometimes they malfunction. If yours isn’t providing cold air, here are some common reasons why:
Refrigerant Leaks
One of the most common reasons for a ductless mini split to stop cooling is a leak within the refrigerant lines. Refrigerant is crucial for the cooling process, as it absorbs heat from the indoor air and releases it outside. If there’s a leak, the system won’t have enough refrigerant to cool the air effectively. Signs of a refrigerant leak include:
- Decreased cooling performance
- Hissing or bubbling sounds from the unit
- Ice buildup on the evaporator coils
To address this, you’ll need a professional technician from Heartland to locate and repair the leak, and then recharge the system with the correct amount of refrigerant.
Compressor Problems
The compressor is the heart of your ductless mini split system, pumping refrigerant through the system. If you have a malfunctioning compressor, the entire cooling process can be compromised. Common signs of compressor problems include:
- The unit not turning on
- Strange noises from the outdoor unit
- The system blowing warm air
Compressor issues can be complex and require a professional diagnosis and repair. If you suspect a compressor problem, it’s best to call Heartland for an expert assessment.
Airflow Restrictions
For your ductless mini split to cool effectively, there needs to be proper airflow. Airflow restrictions can be caused by:
- Clogged air filters
- Obstructed air handlers
- Blocked outdoor units
If you notice reduced airflow, it could be due to a clogged air filter. Clean mini split filters are essential for your air conditioning system. Regularly clean or replace the filters and ensure that nothing is blocking the indoor unit and outdoor air handlers. Checking these components first can help maintain proper airflow and improve your system’s performance.
Electrical Issues
Electrical issues can also prevent your ductless system from producing conditioned air. Problems such as faulty wiring, blown fuses, or tripped circuit breakers can disrupt the system’s operation. Signs of electrical issues include:
- The unit not turning on
- Intermittent cooling
- Flickering display lights
If you suspect an electrical issue, it’s important to call a professional technician. Handling electrical connections without proper knowledge can be dangerous.
More Mini Split Troubleshooting Tips for Marion Homeowners
Before you call for a ductless mini split repair in Marion, IL, there are a few more things you can try to troubleshoot the problem yourself. These simple checks might just get your cool air flowing again and save you time and money.
- Check the Thermostat Settings: Ensure that your thermostat is set to the correct temperature and mode. Sometimes, the issue can be as simple as the thermostat being set to “heat” instead of “cool” or the set temperature being too high. You may also have a faulty thermostat that needs to be replaced.
- Look for Ice Buildup: Ice can still build up on a ductless mini split even in hot weather, which can stop it from cooling effectively. This often happens due to low refrigerant levels or airflow issues. If you notice ice buildup, turn off the unit and let it thaw completely to get it working again. You should still call an HVAC professional to figure out the underlying issue.
- Reset the System: In some cases, resetting the system can resolve minor issues. Turn off the power to the unit, wait a few minutes, and then turn it back on. This can sometimes reset the system and restore normal operation.
