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

The warning signs of an air conditioner’s problem can tell a lot about the kind of issue the system is suffering from. Whether it’s peculiar noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a unique repair. By knowing the specific symptoms, you can figure out the potential causes of the problem and determine the best course of action for repairing the air conditioning system.

While the symptoms are often unique, many cooling system issues stem from problems that can be avoided by scheduling annual air conditioning maintenance. That’s because a routine Air conditioner 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 service. This helps locate potential problems before they cause equipment failures or other issues.

Here are some of of the common AC problems and the signs you may see:

Why Is My Air Conditioner Leaking?

Air conditioning 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, particles or mold, water can back up and start to leak.

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

It's important to address a leaking air conditioner promptly to avoid damage to your home and ensure that your air conditioning system is operating 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 developing in the future.

Why Does My Air Conditioner Freeze Up?

If your AC is freezing up, it might be due to 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 leads to a buildup of cold air in the evaporator coil, causing it to freeze.

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

To fix a frozen air conditioner, it's important to power down the air conditioning so that it can thaw completely. When the system has thawed, examine the air filter, ductwork and refrigerant levels to see if something is broken. Regular maintenance, including changing the air filter and having the system inspected annually by a professional.

Why Does My Air Conditioner Make So Much Noise?

If your air conditioner is making loud noises, it may be an indication that the unit needs service. One common cause of a loud air conditioner is a damaged fan motor or a worn-out fan belt. The loudness might also be a sign the equipment has loose parts such as screws, bolts or bearings, which can cause vibrations and rattling sounds.

A noisy air conditioner also could have a dirty condenser coil, which can obstruct airflow and cause the system to work harder, resulting in more noise. Similarly, a damaged or old compressor can also produce loud noises from the air conditioner.

Why Is My Air Conditioner Not Blowing Cold Air?

One common cause of an air conditioner not making cold air is a clogged air filter. A dirty air filter limit airflow, causing the evaporator coil to become extremely cold and freeze, resulting in not enough cool air. Another plausible cause is a refrigerant leak.

Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, which can result in a lack of cool air coming from your air conditioner. Also, a faulty compressor or motor can also cause the AC not to blow cold air. To address this, it's important to check the air filter and change it if necessary.

Why Won't My Air Conditioner Run or Start?

Your air conditioning system might not switch on because of a tripped circuit breaker or blown fuse. To correct this, inspect the electrical panel and reset any tripped breakers or replace any blown fuses.

The source of the issue also could be a malfunctioning thermostat, which can keep the air conditioner from starting. If that's the case, check the thermostat and change it, if required. Additionally, a problematic compressor, motor or capacitor can prevent the air conditioner from turning on. To address this issue, it's best to contact a professional to inspect and repair the unit.

Should My Air Conditioner Be Making a Loud Noise?

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

One typical cause of weird noises is a deteriorating fan motor or a worn-out fan belt. These two problems can make scraping, squealing or grinding noises. Another possible cause is loose parts such as screws, bolts or bearings.

In addition, a dirty air filter can cause whistling or wheezing noises from an air conditioner, while a refrigerant leak can produce hissing or bubbling noises.

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