AC Issues That Require Professional Troubleshooting

Millennial Magazine- AC issues

If you love to learn how to fix issues in your home, you might be tempted to repair your air conditioner. While there are some issues that you can handle on your own, others are beyond your expertise. Instead of turning a small problem into expensive repairs, it’s best to understand when to leave specific tasks to the professionals. Here are AC issues you’ll need professional help with:

AC Unit Doesn’t Cool Your Home

It can be quite frustrating when your air conditioner isn’t cooling your space. The issue arises when your AC coils have problems. The evaporator coils in the AC absorb the heat in the air before pushing it through the ductwork. However, a defect like a coil corrosion will jeopardize the ability to absorb heat. Depending on damage severity, you might have to replace the coils –a task that requires professional expertise. However, mild defects can be solved with a thorough cleaning.

Similarly, the compressor is a vital component in the heat exchange process. When the refrigerant is imbalanced in your unit, the heating process may work, but cooling will be hard to achieve. It’s best not to attempt to solve compressor issues on your own. Instead, reach out to a contractor for professional air conditioner repair. If it’s been a long time since you cleaned condenser coils, you might need a heating and cooling professional for deep cleaning to ensure they are in perfect condition.

Refrigerant and Water Leaks

Leakages are the easiest to spot and account for about 90% of AC service requests. You should get a flashlight and check the corners and leaking areas to determine if the overflow pan is causing the issue. If you see a leaking hole, don’t attempt DIY repairs because it will reappear in a few days. Instead, buy a new pan and call a professional for installation.

Alternatively, the leaks can stem from a clogged condenser line. If the issue is ignored, the unit will shut down and fail to start. You can prevent this by scheduling immediate maintenance to clean the junk from the unit to prevent further damage.

Strange Noises From the Unit

It’s irritating when your AC makes strange noises like buzzing, rattling, hissing, clanging, and banging. However, you should consider the noise as a signal telling you something is wrong. For instance, if you notice a hissing noise, your AC is likely losing air through leaks in the ductwork. This could also mean a problem with your AC filter, forcing air to escape through a gap.

On the other hand, banging and clanging noises often mean loose parts in your system. Specifically, the motor fan might have loose connections, or the pipes in your system are disintegrated. Rattling sounds may come from twigs and leaves stuck in your equipment. These issues require prompt action because they can lead to severe damage and compromise the longevity of your AC. It is best to turn off the system before contacting a professional for troubleshooting and repair.


Some common HVAC issues can be easy to troubleshoot and fix on your own. However, others are complex, and you can end up with a bigger problem if you attempt the repairs yourself. Regardless of your confidence in your DIY capabilities, it’s prudent to leave some AC issues to professionals.
