Is your AC acting strange? If so, it's good to pay attention because 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 experiencing. Whether it’s weird noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a unique fix. By knowing 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 regular 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 service. This helps uncover potential problems before they cause breakdowns or other issues.

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

Why Does My Air Conditioner Leak?

Air conditioning leaking water can be a widespread issue. One of the most common causes of an air conditioner leak is a plugged condensate drain line. The condensate drain line is designed to remove excess moisture from the air conditioning system. When this line becomes slow or stopped up with dirt, particles or mold, water can back up and start to leak.

Another typical explanation for water leaking from an air conditioner is a damaged or rusted drip pan, which can permit water to overflow and leak out of the unit. Additionally, a refrigerant leak or a busted pump could also cause water to leak from an AC unit.

It's necessary to address a leaking air conditioner promptly to prevent damage to your home and make sure that your air conditioning system is functioning efficiently. Routine air conditioner maintenance, including replacing 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 because of a variety of reasons. One typical cause of a frozen air conditioner is limited airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This can cause a buildup of chilled air in the evaporator coil, causing it to freeze.

Another reason your air conditioner is frozen might be low 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 frosty air and cause the evaporator coil to freeze.

To fix a frozen air conditioner, it's important to power down the air conditioner so that it can thaw completely. After the system has thawed, check the air filter, ductwork and refrigerant levels to see if anything is malfunctioning. Regular maintenance, including replacing 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 might be an indication that it needs service. One common cause of a loud air conditioner is a broken fan motor or a worn-out fan belt. The loudness 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 hinder airflow and cause the system to work harder, resulting in greater noise. Similarly, a damaged or old compressor can also cause 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 clogged air filter. A dirty air filter limit airflow, causing the evaporator coil to become too cold and freeze, resulting in not enough cool air. Another potential cause is a refrigerant leak.

Low refrigerant levels might 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. In addition, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To address the issue, it's important to check the air filter and exchange it if necessary.

Why Is My Air Conditioner Not Working or Not Turning On?

Your air conditioning system might not switch on because of a tripped circuit breaker or blown fuse. To fix this, look at 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 prevent the air conditioner from turning on. If that's the case, check the thermostat and change it, if necessary. Additionally, a faulty compressor, motor or capacitor can stop the air conditioner from turning on. In this case, it's best to get in touch with a professional to inspect and repair the unit.

Why Is My Air Conditioner Making a Weird Noise?

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

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

Furthermore, a blocked air filter can cause whistling or wheezing noises from an air conditioner, while a refrigerant leak can make hissing or bubbling noises.

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