If you’ve been using an air conditioner for a while, you will understand just how important it has been in ensuring a comfortable environment inside your home. Unfortunately, there are times when the AC fails to do its job, whether it be because of an ongoing leak or a sudden fault that has caused it to struggle to perform. These issues can happen at the worst of times—and the only way to prevent such things from happening is to carry out proper and frequent maintenance.

One of the best things you can do for your AC is to hire professionals to maintain your AC regularly. There are many tasks that can be tough to do without proper knowledge—let alone the proper equipment—that only the experts have access to. 

That said, if you are curious to know what professional AC technicians do exactly to maintain your AC, here is a list of things they generally do:

1. Cleaning out the air filters

Although this might be something you can easily do yourself, a trained professional can check to make sure that the filter is still in good condition and that it doesn’t need replacing. Of course, if it needs to be changed, then they will recommend that course of action for you. They will then pick the right type of air filter to fit in your AC system to ensure clean air is easily pumped throughout the system!

2. Checking the refrigerant levels

One of the most critical parts of the AC system is the refrigerant. Without it, the AC system will struggle to cool air, failing to achieve its main purpose. 

When working with the professionals, they will test the refrigerant levels to see if it needs to be recharged. If it has dropped significantly, they may look around for potential leaks to ensure the levels aren’t dropping quickly. After diagnosing and addressing the issue, they will refill the refrigerant for you, ensuring the AC is working at peak performance! 

3. Analyzing the electrical connections 

Because there are a lot of vibrations occurring in your AC system, there’s always the risk of some of the electrical connections loosening up. This can cause failures in your system, stopping the entire system from working at all. 

To stop this from happening, technicians will look around and test each electrical connection there is, tightening them as necessary to ensure they do not loosen up anytime soon. 

4. Testing the fan and compressor motors

The fan and compressor motors are responsible for moving air throughout the AC system and are one of the parts of the AC that endures the most amount of stress. During maintenance, the professionals will thoroughly clean the fan and compressors from any dirt and debris, and will also lubricate them to ensure each part runs smoothly without stressing the components.


These are just some of the many things that AC technicians can do when maintaining your AC system. Note that what a technician does exactly can differ slightly from one home to another. That’s because different ACs in different homes aren’t exactly in the same state all the time! Needs can be different, but the technician will know exactly what to do to ensure that the AC is well maintained to offer maximum performance for many years to come. 

That being said, whether you need your AC cleaned or a component fixed, hire a technician to do it for you! They have the skills and tools to do the job, and they will make sure it is done the right way.
