Ductless mini-split systems allow you to achieve zoned heating and cooling in your home without the need to install central ductwork. Sometimes, you might encounter problems with the mini-split system, and it’s important to learn how to troubleshoot problems with the unit to ensure it gives you the best services possible. Read on to understand some of the potential issues you may encounter with a ductless mini-split and how to troubleshoot it in your Grovetown, GA, home.

Inspect the Outdoor Unit

The ductless mini-split system consists of an indoor air handler and an outdoor unit. If you notice problems with the mini-split system, inspect the outdoor unit for the buildup of dirt and other debris that can cause potential damage to the outdoor unit, affecting its ability to deliver hot and cool air to your home.

Ice buildup on the outdoor unit will cause poor airflow, especially during the hottest months of the year. Your HVAC technician can dust and lubricate the system to eliminate ice buildup, ensure efficiency and ensure proper airflow.

Adjust the Temperature Settings

If you notice that your ductless mini-split system isn’t turning on, you should check the display panel to identify problems with the temperature system settings. The temperature settings should be high or low enough to trigger the ductless mini-split system. You should also ensure that the display panel shows the correct mode, such as cooling for winter and heating for summer.

To heat your home, you should set the temperatures above the current room temperature, and to cool the room, set the temperatures slightly below the existing room temperatures. If this doesn’t turn on the ductless mini-split, you should schedule preventive maintenance with your HVAC technician.

Check the Power Voltage Lines

Different ductless mini-split systems require a certain level of voltage to function. Therefore, always ensure that your mini-split system connects to the right voltage. Sometimes, problems with your electric system can lead to too high or too low voltage, which can cause damage to the mini split’s board.

Before powering up the ductless mini-split system, you should check the voltage reading to ensure it’s within the approved range. It would help to use a surge protector to shield your ductless mini-split from electrical damages. If you reside in Grovetown, GA, schedule the maintenance and repair of your ductless mini-split with our technicians at Plunkett Heating & Air.
