What Causes a Ductless Mini-Split To Break?

Someone's hand hovering over a mini-split vent, feeling the airflow.

A ductless mini-split system has a dual cooling and heating function, allowing for greater temperature control. Through the installation of outdoor and indoor units, ductless mini-splits extract or release heat. While this system has a longer lifespan than traditional ACs, extended use in hot climates can contribute to breakdowns, which is why routine maintenance is critical. 

These are the top six common reasons ductless mini-splits break:

  1. Improper installation
  2. Overheating compressor 
  3. Lack of routine maintenance 
  4. Low refrigerant levels
  5. Condensate pump failure
  6. Faulty thermostat

Repairing vs. Replacing Your Ductless Mini-Split

Ductless Mini-Split Repair FAQs

How long does a ductless mini-split system last?

If regularly maintained, a ductless mini-split can last 15 to 20 years. It’s one of the most durable HVAC systems, making it a popular and energy-efficient choice.

How can I best maintain my ductless mini-split?

Enjoy zoned temperature control for longer with simple at-home steps. We recommend you replace your air filters every other month and keep coils free of dust. Regularly check outdoor units and keep the area around them clear of dirt buildup or debris. Scheduling annual maintenance will ensure minor problems with your system don’t become a major expense.

Will a ductless mini-split heat and cool my entire home?

If properly installed, a ductless mini-split system is a whole-home solution. A single indoor and outdoor unit will exchange or remove heat, allowing you to control and modify the temperature in every room individually.
