No matter the season, one thing every home depends on is the air conditioning system. Some days are hotter than others, and it is an AC’s job to adjust the airflow and provide the much-needed temperature that fits your comfort levels. Here are some signs you need to call a professional for a tune-up.

4 Signs You Need to Call a Technician for an AC Tune-up

Air Conditioning Is Weak

If your AC needs to be on its highest setting to generate a moderate room temperature, this may indicate that it is growing weak. This can happen to old AC units, especially those subjected to years of neglect. The inadequate airflow can mean clogged filters, leaking ducts, or both. An accumulation of dirt can also cause these things. 

Tune-ups by professionals can clear all the gunk away to improve airflow. Thorough cleaning is one of the things that can make a big difference in air conditioner performance. In addition, professionals may be more qualified to take on the job because they have the equipment to protect them from anything hazardous. 

The Energy Bills Are High

Any machine dialed up to the highest setting unsurprisingly means you would have to pay more because it takes quite a bit of energy to run on overdrive all the time. While this might be normal on abominably hot days, it shouldn’t last months. This is a sign that your AC needs a tune-up. 

More often than not, technicians can fix them right away. You will likely end up saving more money in the long run. 

There’s a Weird Sound 

A humming or buzzing sound from your unit may be a sign of clogs or internal damage. These may indicate that your AC is on the verge of breaking. Therefore, it would be wise to call a technician right away for an inspection. Once the problem has been discovered, they can repair it then and there rather than allow you to tolerate the sound.

There’s an Odd Smell

Leaks and sounds may seem within the realm of not-so-strange possibilities. However, one unusual telltale sign that something is wrong is if it starts to smell odd. 

Anything that smells like burning or oil may just be due to faulty wiring or leaks. Pungent smells coming from the air conditioner may signify a wet clog or mold and mildew buildup inside the system. Finally, the oddest smell you may notice is a rotting stench, which could suggest a dead animal inside.

To steer clear from these things, hire an expert experienced and prepared for these unusual scenarios. 


Your air conditioning unit is one of the most important things you should be concerned about. The longer you put off repairing it, the more you may end up paying in bills and repairs. Having an expert fix these issues can save you time and money to make your home comfortable again.
