Diagnosing and Repairing a Faulty Mini Split Compressor

Having a faulty mini split compressor may seem like a daunting task, but with the right information and a few repairs, you’ll be able to get your system back up and running in no time. Mini split compressors often require maintenance and repair at least once a year. A faulty compressor may lead to a dramatically shorter life span for the system, so it’s essential to know how to diagnose and repair the problem if it arises.

Symptoms of a Faulty Mini Split Compressor

If you start to notice any changes in air flow, a noticeable decline in air temperature, or odors coming from your mini split, it could mean there’s an issue that is causing your compressor to fail. Other signs of a faulty mini split compressor may include:

  • Foul Odors – If your mini split compressor is emitting a foul smell, it’s likely a sign that the wiring has been damaged and needs to be repaired.
  • Noisy Vibrations – If you notice a loud and persistent vibration coming from the compressor, it could mean that the bearings and other internal components of the compressor have worn down and need to be replaced.
  • Air Flow Changes – If your mini split compressor isn’t functioning properly, it will often result in a sudden change in air flow or a noticeable decrease in air temperature.

Mini Split Compressor Problem: Best Practices for Prevention

Mini split air conditioners and heaters are becoming increasingly popular due to their convenience and affordability. Although they are generally low maintenance systems, one issue that can arise is the compressor failing. In order to avoid this issue and make sure the mini split unit is running optimally, here are some of the best practices for preventive maintenance of a mini split system.

Manufacturer Recommendations

The manufacturer of the mini split system is the best resource for advice on how to maintain the mini split compressor. According to a manufacturer of mini split systems, these are the steps one should take to ensure the compressor runs without fail:

  • Regularly inspect the filter – A clogged filter can negatively impact the mini split unit’s performance and should be assessed frequently.
  • Clean the heat exchanger on a regular basis – Dust and debris can build up in the heat exchanger and decrease the efficiency of the system. It should be cleaned at least once every two to three months.
  • Get the system serviced annually – An annual inspection and tune-up by a qualified HVAC technician can help identify and rectify any potential issues before they become a more significant problem.

Local Appliance Companies and HVAC Technicians

In addition to the manufacturer’s recommendations, HVAC technicians and local appliance companies can provide you with further advice about how to maintain a mini split compressor to avoid issues. Here are some of their recommendations:

  • Utilize an air purifier – An air purifier can reduce dust, pollen and airborne particles in the area around the mini split system and help keep the compressor clean and free from obstruction.
  • Check pressure and temperature levels – Low pressure or temperature levels can be signs of leaks or blockages in the system. It is important to monitor and maintain these levels in order to keep the mini split functioning properly.
  • Install a surge protector – A surge protector can protect the mini split compressor from power surges and other electrical issues.


When properly maintained, a mini split compressor should perform reliably for years to come. Regular inspections and tune-ups, in addition to cleaning and pressure/temperature checks, can help avoid costly problems down the line. For more advice on having a mini split system serviced or inspected, always contact a qualified local appliance company or HVAC technician.
