Your air conditioner does the critical job of keeping you cold and comfortable during unbearably warm summer months. However, when it starts to malfunction, it’s essential to have it repaired right away, so it works when you need it the most. You don’t want it to break down in the middle of a heatwave, after all!

Fortunately, having HVAC services swing by and maintain your system is a great way to prevent these issues. If your AC starts sputtering or stops working, you’ll probably want to do everything you can to get it back up and running right away. Here are five tips for troubleshooting your air conditioner:

Inspect the Basics

The first thing to do when your AC stops working is to check the circuit breaker. Sometimes, your air conditioner is working just fine, and the problem lies in the circuit. For instance, the plug may be loose, and securing it into the outlet may do the trick in bringing your AC back to life.

Alternatively, you may want to check your thermostat as well. You may believe that there is a problem with your AC, but it’s really in the thermostat. Ensure that it is completely connected to a power source and that it is operating in cool mode. 

Familiarize Yourself With Your AC Unit

If everything checks out in the previous tip and your AC still isn’t working, it’s important to familiarize yourself with it and understand how it works. The more you know about it, the more you’ll understand how to keep it working correctly. It will also make sure you practice effective maintenance and avoid costly utility bills.

Getting acquainted with your AC can also come in handy when your air conditioner is malfunctioning. Some homeowners don’t know that their AC systems have on/off switches, which may cause them to think that their air conditioners aren’t working when in reality, the switch was put in the off position.

Check Your Filter

Another reason your air conditioner may not be working is that your filters are clogged with dust and debris. When it’s overloaded with grime, it prevents your air conditioner from working correctly while forcing it to use more energy to cool your home. Not only will it tax your AC system, but it will also result in sky-high electricity bills. 

To avoid this, replace your filter regularly. Doing this will also extend your AC system’s lifespan and keep it in good condition since it won’t have to overwork itself to maintain a cooler temperature in your home while contending with dirty filters.

Look at Your Evaporator Coils

Another part of your AC that must stay clean is your evaporator coils. However, it’s best not to do this yourself, as it requires the expertise of an AC repair technician since it involves a dedicated method. Still, checking your evaporator coils and assessing their condition will also give you an idea of what may be causing your AC to malfunction.

Call AC Repair Technicians

If you’ve covered the basics and your AC still isn’t working properly, it’s time to call air conditioning services. These professionals are well-versed in all things HVAC, which means they’ll pinpoint the cause of the problem and address it right away. They can also clean, maintain, and tune-up your AC system, ensuring it works properly and keeps you cool and comfortable during hot weather. Some problems are simply beyond the scope of basic troubleshooting, so if you notice your air conditioner acting oddly, it’s best to call an AC repair service.


Your air conditioner is one of your most important appliances, giving you the comfort you need when it’s sweltering outside. When something goes wrong, you’ll want to make sure you can address the problem right away. By following these tips, you’ll enjoy a well-working air conditioner that will keep you cool when you need it.
