A ductless mini-split system offers several benefits to your home, but what would you do if the system suddenly stopped functioning? This guide discusses some common issues affecting ductless systems and how a professional HVAC technician in Woolsey, GA, can diagnose and fix these problems.

Problems With the Outdoor Unit

The ductless mini-split system comprises an outdoor unit and one or more indoor units. If your mini-split system suddenly stops working, you should check the outdoor unit for the buildup of unwanted debris. Dirt buildup can damage the outdoor unit because it restricts airflow, causing inadequate heating and cooling.

Damage to the outdoor unit might also happen due to ice buildup. To avoid this, you should schedule regular preventive maintenance services, where technicians will regularly clean check the refrigerant in the mini-split to prevent ice buildup.

Refrigerant Leaks

The modern mini-split system uses an environmentally friendly refrigerant known as R-410A. This refrigerant solution is responsible for circulating cool air in your home through cables. Pests can cause wear and tear of the lines, causing refrigerant leaks.

Refrigerant leaks can cause poor performance of the unit, making it continuously turn on and off and not blow cool air in your living space. A professional HVAC technician can diagnose and fix these leaks and refill the refrigerant to ensure that the mini-split adequately cools your house.

Poor Voltage Supply

For a ductless mini-split to function correctly, it must be connected to the proper voltage. Too little or too much power flowing to the mini-split can cause damage to the system’s board.

Always check for any possible wear and tear on your cord and plug before turning on the ductless mini-split. You should also monitor the voltage at the power unit before turning on the system to ensure it is within the manufacturer’s range.

Dirty Vents and Air Filters

Dirt and dust may slowly accumulate in the mini-split’s vents or air filters, causing a reduction in its cooling efficiency. To prevent this, you should schedule maintenance services, where your technician will replace the air filters.
