When summer temperatures start to soar, a reliable air conditioning (AC) system is essential for staying comfortable and healthy. However, just like any other appliance, AC units can experience issues that disrupt their normal functioning.
Troubleshooting your AC can help you save time and money by identifying and addressing problems before they worsen or lead to costly repairs. With the right knowledge and tools, you can perform some DIY troubleshooting steps to get your AC unit back up and running in no time. You can also contact a professional for help if the issue persists. Here are some ways to troubleshoot your AC:
Check Power Supply
The first step in troubleshooting your AC is to check its power supply. A power outage or tripped circuit breaker can easily shut down your AC unit, leaving you feeling hot and uncomfortable. Start by inspecting your circuit breakers and fuses to ensure that they are not tripped or blown. Next, check your thermostat and make sure it is set to the correct temperature and mode.
If your AC unit has a power switch, make sure it is in the “on” position. If none of these steps work, you can contact AC experts to get it repaired and also test for power issues. They will also do some tests to ensure no electrical problems are associated with the AC unit.
Clean or Replace Filters
If your AC is not cooling properly, it may be due to a clogged filter. Inspect and clean the filters at least once a month, as they trap dust, dirt, and other particles that can cause AC problems. If you have an older model of air conditioner, consider replacing the filter with a newer, more efficient one for better performance.
Be sure to check your user manual for instructions on how to replace the filter. Once you have replaced the filter, clean the inside and outside of your AC unit regularly for maximum efficiency. You can hire an AC technician to do a full system check and replace the filter if needed.
Check the Outdoor Unit
The outdoor unit of your AC system is responsible for releasing the heat absorbed from inside your home. It’s crucial to keep this unit clean and free of debris to ensure optimal functioning. To inspect the outdoor unit, start by checking for any signs of physical damage or debris buildup, such as leaves or twigs.
Use a soft-bristled brush or vacuum to clean the unit’s fins and coils, taking care not to damage them. You can also spray the unit with a garden hose to remove any dirt or grime. If you notice any issues with the outdoor unit, such as strange sounds or unusual vibrations, it may be time to call a professional. You may need a complete HVAC replacement if the issue with your outdoor unit is too serious. It is therefore crucial to find the best HVAC professional in your area to ensure the job is done right and to prevent any future issues with your unit.
Check the Air Ducts

Air ducts play a vital role in distributing cool air throughout your home. Dirty or clogged air ducts can cause reduced airflow, which can impact your AC system’s efficiency and performance. To check your air ducts, start by inspecting the air vents for any signs of dirt or debris.
Remove the vent covers and clean them with a soft brush or vacuum if you notice any. Next, use a flashlight to check the ducts for any visible dirt or debris. You can also hire a professional to clean your air ducts thoroughly. If you continue to experience issues with your AC system, it’s best to call an HVAC professional to diagnose and fix the issue.
AC troubleshooting can help you save time and money while ensuring that your AC unit stays in good condition. Following these steps can quickly identify and fix common AC issues. Remember to perform regular maintenance to keep your AC unit running smoothly and efficiently, and call a professional if you’re unsure about any troubleshooting steps.
