Most Common Split AC Problems and Learn How to Fix

Moisture and heat are removed from space by an air conditioning system, and they are replaced with cold air. However, if you are using your air conditioner after winters, you may have run into several issues.

As a result, taking the necessary precautions and performing regular maintenance on your home’s air conditioning system will help you avoid an unpleasant and sweaty day, and enjoy your time with loved ones. We’ve gathered five of the most prevalent split-system difficulties and solutions for each.

Most Common Issues with a Split AC System

Here are listed some of the common issues of a split ac with their solution-

Problem 1: The Split Air Conditioner is Not Powering Up

Solution- A basic AC troubleshooting tutorial is all that is needed to fix the problem. Make sure that your split system air conditioner has electricity.

If this is the case, make sure the thermostat is set to ‘cool.’ If all the exterior wiring is intact, rats and mice might gnaw through the wires and disconnect the circuits.

The next step is to ensure your home’s electrical wiring is in good working order. Resetting the power should solve any problems with blown fuses or tripping circuit breakers.

Your split system air conditioner may have wiring or motor problems if all of the above fails. You’ll need to contact an AC repair and maintenance company if that’s the case.

Problem 2: Split AC Always Running

Solution- You must be wondering why the mini-split is always running. Airflow restriction is one of the most prevalent causes for an air conditioner to operate continually in the summer.

In order to provide cold air to your house, your air conditioner requires a particular quantity of airflow.

If anything is obstructing the airflow to your air conditioner, your system will have to work harder in order to bring in a sufficient volume of air to compensate.

Problem 3- Mould in the Air Conditioner

Solution- When dealing with mold, it’s essential to know that molds are fungi that thrive in damp conditions. Split-system air conditioners provide the ideal growing environment because of the constant, even temperature.

The sooner you address them, the better off you’ll be in the long run. Contact an air conditioner repair technician as soon as possible to fix this split system air conditioner issue.

Problem 4- AC Does Not Blow Cool Air

Solution- There may be split AC issues causing hot air to be blown out of the vents. The thermostat should be set at least five °C lower than the room temperature as the first step in solving the issue.

Further reducing the temperature will reveal whether or not the cooling effect has occurred. After 15-20 minutes, remove the debris from the evaporator or condenser thoroughly if the output is the same. Make that the condenser’s coils and fins are getting enough air.

Problem 5- Indoor Unit Making Too Much Noise

Solution- Split air conditioners’ interior units may make a lot of noise while running or when they first turn on. In this case, the fan in the indoor unit is to blame.

The technician will disassemble the indoor unit and reinstall the fan in its original position. Dust and grime may build up on the fan, causing it to vibrate, resulting in noise. This can be solved by dismantling and cleaning the fan.


A split air conditioner needs regular maintenance to ensure that it operates smoothly. It is also essential to be aware of the most frequent air conditioning issues to take preventative actions to avoid costly repairs in the future.
