How to Troubleshoot Your AC System

How do you troubleshoot an AC system? As the warmer months of summer approach, it is critical to check that your air conditioning unit is operating as it should before the heat sets in. It is essential to perform system troubleshooting if you have seen that your air conditioner is not effectively cooling your home as it should, or if it has completely stopped functioning. The following is some advice that can be used to diagnose and fix common issues with air conditioners.

How do you troubleshoot an AC system?

Check the Thermostat

Your air conditioner’s control centre is located in the thermostat. It not only determines when the air conditioner should turn on and off, but it also regulates the temperature in your home. The thermostat is the first thing you should look at if your air conditioner isn’t functioning properly. Make sure that it is set to the “cool” position, and that the temperature is set to a level that is lower than the temperature in the room. If the thermostat is acting erratically, you should replace it.

Inspect the Air Filter

If your air filter is unclean, it may limit airflow, causing your air conditioner to work harder than it should have to. Check the air filter if your air conditioner isn’t cooling your home as effectively as it should be. If it’s unclean, you should get a new one. Every three months, or more regularly if you have pets or allergies, you should change the filter in your air conditioner or furnace.

Clean the Condenser Coils

The condenser coils, which are situated outside of your home, are the components that are in charge of dissipating the heat produced within. If the condenser coils are dusty or obstructed, they are unable to effectively release heat, which can cause your air conditioner to either stop working altogether or fail to adequately cool your home. Turning off the power to your air conditioner is the first step in the process of cleaning the condenser coils. Next, use a gentle brush or a vacuum to remove any debris or dirt that has accumulated on the coils. For air con repair breakdown services see here.

Check the Refrigerant Levels

If there is not enough refrigerant in your air conditioner, it may blow heated air or perhaps stop working entirely. Check the amounts of refrigerant in your air conditioner if you find that it is not effectively cooling your home. In the event that they are low, you will have to get in touch with a qualified technician to have additional refrigerant added. Because low amounts of refrigerant can be an indicator that a leak is present, it is essential to have a trained professional inspect your system for leaks.

Inspect the Electrical Connections

It is conceivable that the issue is with the electrical connections in your home if your air conditioner does not turn on at all. Verify that the power is turned on and that all of the connections to the various electrical outlets are tight. If you find any connections that are slack, you should tighten them. In the event that working with electrical connections makes you feel uneasy, you should contact an expert.

Call a Professional

If you’ve gone through all of these troubleshooting steps and your air conditioner is still not functioning properly, it’s time to call in an expert. A qualified HVAC specialist will be able to diagnose the issue and make repairs in a timely and risk-free manner. If you try to remedy the problem on your own, you run the risk of injuring yourself and doing more harm to your air conditioning system.


You may avoid any problems with your air conditioning system by following these troubleshooting guidelines and putting them into practise. The majority of problems that can arise with an air conditioner can be avoided by performing routine maintenance and inspections. If you do find a problem, it is imperative that you solve it as soon as possible in order to prevent the need for more costly repairs in the future. Keep in mind that it is always advisable to consult a professional if you are not comfortable working on your air conditioning system alone. How do you troubleshoot an AC system?
