If you own a ductless mini-split heating, ventilation, and air conditioning system in your Peachtree Corners, Georgia home or business, you are familiar with their benefits. However, their state-of-the-art technology can make them difficult for homeowners to troubleshoot when things go wrong. Ductless systems often require a qualified service technician to diagnose and correct malfunctions. Common problems include poor cooling or heating and icing up. Here are a few troubleshooting tips to check before calling for professional ductless HVAC repairs.

Not Heating or Cooling

There are several reasons a ductless HVAC may not produce conditioned air:

  • Check the filter. Lack of maintenance and dirty filters are common reasons that HVAC systems malfunction. Cleaning or changing filters is a simple task that homeowners can do.
  • If the fan runs but the unit does not produce conditioned air, check the thermostat setting. If the ambient air temperature is close to the set temperature, the compressor may not come on. Adjust the thermostat to see if the unit begins to heat or cool.
  • There may be a refrigerant leak. Mini-split heat pumps use refrigerant for both heating and cooling. Qualified service technicians are trained to test for refrigerant leaks and repair them.

Icing Up

Heat pumps have a defrost mode to prevent icing up. Ice formation is usually a sign of low refrigerant. Alternatively, poor airflow over coils can cause the condenser to ice up. If the defrost mode does not solve the problem, call a professional for ductless HVAC repairs.

Circuit Board Error Code Displays

Although ductless systems appear to be simple, they contain sophisticated, complex wiring and technology. Circuit boards display error codes that signal why the unit is malfunctioning. Codes are different for each brand and model. Technicians trained in ductless HVAC repairs understand how to read these codes and investigate the source of the problem.
