Ductless Mini Split Repair in Mason, OH

Why Does My Mini Split Keep Shutting Off?

There’s nothing more frustrating than a mini split shutting down on a scorching day. Here are some common culprits:

  • Thermostat Settings: Double-check your thermostat settings. Is the desired temperature set lower or higher (depending on the mode) than the current room temperature? A properly set thermostat ensures the system only runs when cooling is needed.
  • Dirty Air Filters: Clogged filters restrict airflow, causing the unit to overheat and shut off as a safety measure. Clean or replace your filters regularly (usually monthly) to prevent this.
  • Low Refrigerant Levels: Refrigerant is the lifeblood of your mini split, absorbing heat and releasing it outdoors. Leaks or low refrigerant levels trigger a safety shutoff. Professional repairs are necessary to fix these issues.
  • Frozen Coils: Restricted airflow over the evaporator coil can cause it to freeze. This could be due to dirty filters, blocked vents, or a faulty defrost cycle. A technician can identify the root cause and rectify the issue.
  • Electrical Issues: Faulty wiring, a blown fuse, or a malfunctioning circuit board can interrupt power supply to the unit, causing it to shut off. Let a professional electrician address any electrical concerns.
  • Sensor Issues: Faulty sensors can send inaccurate information to the control board, causing the unit to shut down prematurely. A technician can diagnose and replace malfunctioning sensors.

If your ductless mini split keeps turning off before reaching your desired temperature, don’t ignore this issue. Robinson Heating and Air Conditioning, Inc. is available to solve the above problems as well as any other malfunction you may encounter with your mini split system.

Should I Repair or Replace My Mini Split?

Making the repair-or-replace decision requires considering factors like age, repair cost, and efficiency. 


If your mini split is less than 10-15 years old, repairs are often a cost-effective option to keep your unit in service longer. Our technicians perform thorough diagnostics so you know exactly what issues your system faces and can make an informed decision regarding your repair needs.


For units nearing or over 20 years old, frequent repairs, declining efficiency, and outdated technology might make a replacement more cost-effective in the long run. Extensive repairs involving refrigerant leaks or compressor failure might justify a system replacement. Robinson Heating and Air Conditioning, Inc. can help you weigh your options and perform ductless mini split installation if a new system is needed.
