Is your air conditioning acting weird? There's a good chance it’s trying to tell you something.

The signs of an air conditioner’s problem can tell a lot about the sort of issue the system is experiencing. Whether it’s weird noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a specific repair. By identifying the specific symptoms, you can identify the potential causes of the problem and determine the best course of action for repairing the unit.

While the symptoms are often distinct, many cooling system issues stem from problems that can be avoided by scheduling annual air conditioning maintenance. That’s because a routine AC maintenance call includes an inspection and cleaning of your system, as well as finding any parts that may be wearing out and need replacement or to be fixed. This helps find potential problems before they cause equipment failures or other issues.

Here are some of the top AC problems and the signals you may see:

Why Do AC Systems Leak?

An air conditioner leaking water can be a frequent issue. One of the most common causes of an air conditioner leak is a blocked condensate drain line. The condensate drain line is responsible for removing excess moisture from the air conditioning system. When this line becomes plugged with dirt, debris or mold, water can back up and start to leak.

Another potential cause of water leaking from an air conditioner is a damaged or rusted drip pan, which can enable water to overflow and leak out of the unit. Additionally, a refrigerant leak or a broken pump might also cause water to leak from an AC unit.

It's crucial to address a leaking air conditioner right away to avoid damage to your home and ensure that your air conditioning system is running efficiently. Regular air conditioner maintenance, including exchanging the air filter, taking a look at the condensate drain line and inspecting the unit for damage can help prevent leaks from occurring.

What's the Reason My Air Conditioner Freezes Up?

If your air conditioner is freezing up, it might be because of a variety of reasons. One common cause of a frozen air conditioner is restricted airflow, which can be caused by a plugged air filter, obstructed ductwork or closed vents. This can cause a buildup of frigid air in the evaporator coil, causing it to freeze.

One more reason your air conditioner is frozen might be insufficient refrigerant levels, which can cause the evaporator coil to become very cold and freeze. Leaking ducts or damaged insulation can also cause the buildup of cold air and cause the evaporator coil to freeze.

To fix a frozen air conditioner, it's important to turn off the system so that it can thaw completely. Once the system has thawed, examine the air filter, ductwork and refrigerant levels to see if anything is malfunctioning. Regular maintenance, including changing the air filter and having the system inspected annually by a professional.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it may be a sign that your AC needs service. One prevalent cause of a loud air conditioner is a damaged fan motor or a failing fan belt. The racket could also be the result of loose parts such as screws, bolts or bearings, which can cause vibrations and rattling sounds.

A noisy air conditioner also might have a dirty condenser coil, which can block airflow and cause the system to work harder, resulting in increased noise. In addition, a damaged or old compressor can also be a reason you hear loud noises from the air conditioner.

Why Is My Air Conditioner Not Blowing Cold Air?

One common cause of an AC not producing cold air is a blocked air filter. A dirty air filter can significantly slow airflow, causing the evaporator coil to become very cold and freeze, resulting in insufficient cool air. Another plausible source of this issue is a refrigerant leak.

Low refrigerant levels may also cause the evaporator coil to become too cold and freeze, which can result in a lack of cool air coming from your air conditioning. Also, a faulty compressor or motor can also cause a lack of cool air. To fix the issue, it's important to examine the air filter and exchange it if necessary.

Why Won't My Air Conditioner Run or Start?

An air conditioner might not switch on because of a tripped circuit breaker or blown fuse. To repair this, look at the electrical panel and reset any tripped breakers or switch out any blown fuses.

The source of the issue also could be a malfunctioning thermostat, which can prevent the air conditioner from starting. If that's the case, check the thermostat and change it, if necessary. Also, a problematic compressor, motor or capacitor can stop the air conditioner from turning on. If that's the situation, it's best to get in touch with a professional to inspect and repair the unit.

Why Does My Air Conditioner Make Weird Noises?

In addition to the problem of air conditioners working louder than they are supposed to, sometimes they also make peculiar noises.

One typical cause of weird noises is a broken fan motor or a worn-out fan belt. These two issues can cause scraping, squealing or grinding noises. Yet another commonly observed cause is loose parts such as screws, bolts or bearings.

Additionally, a clogged air filter can cause your air conditioning to make a noise similar to wheezing or whistling, while a refrigerant leak can cause hissing or bubbling noises.

As with a lot of air conditioner predicaments, the root cause of strange noises is often something that can be reduced by regular air conditioning maintenance.
