LG Split System Air Conditioners

Common air conditioner problems are very annoying, especially when they occur during the peak of summer, disrupting comfort and causing inconvenience to residents.

Some common issues crop up from time to time if your air conditioner does not turn on or is making a weird noise; read on for some potential problems and how to fix them.

A broken air conditioner is like the red light on your car – it means there is something not quite right with your unit. A functioning and well-repaired AC will keep you cool in the summer and warm in the winter.

However, if your AC is not working well, then it could be one of these common problems. In this blog post, we will explore different ways you can identify which potential problem is affecting your air conditioning unit.

3 Tips To Diagnose Common Air Conditioner Problems

If your air conditioner is not working the way it should, it might be experiencing one of these three common problems. It includes:

Common Air Conditioner Problems Needed to check

One of the first things you should check is whether or not your AC unit is receiving power. To do this, locate the main power switch and ensure it is turned on.

You will also need to check the circuit breaker to see if it is turned on. The circuit breaker is located in the main electrical panel and controls the power to your AC unit.


If the breaker tripped, reset it and try turning on your AC unit again. When the issue persists, it’s recommended to seek professional assistance to diagnose and rectify the underlying problem.

The Air Conditioner Is Not Blowing Cold Air

If your air conditioner is receiving power but is not blowing cold air, a few potential issues could be causing the problem. One possibility is that the air filter is dirty and needs to be replaced. A dirty air filter can restrict airflow and cause your AC unit to work harder than it needs to

Another possibility is that the evaporator coils are frozen. It can happen if the air conditioner is not receiving enough power or there is a problem with the refrigerant levels.

The Air Conditioner Is Leaking Water

If your air conditioner is leaking water, then some issues could be causing the problem. One possibility is that the drain pan is full and needs to be emptied. The drain pan is under the AC unit and collects water drips from the evaporator coils.

Another possibility is that the condensate pump is not working correctly. The condensate pump is responsible for moving water from the drain pan to the outside of your home.

If the condensate pump is not working, water will build up in the drain pan and eventually start leaking from the AC unit. You will need to call a professional to service the condensate pump.
