Is your air conditioning acting unusual? Chances are, it’s trying to tell you something.

The warning 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 ailment—it all points to a particular culprit and requires a specific remedy. By knowing the specific symptoms, it's possible to identify the potential causes of the problem and determine the best course of action for repairing the AC.

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 locating any parts that may be wearing out and need replacement or repair. This helps locate potential problems before they cause breakdowns or other issues.

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

Why Do AC Systems Leak?

A cooling system leaking water can be a frequent issue. One of the most common causes of an AC leak is a clogged condensate drain line. The condensate drain line is designed to remove excess moisture from the air conditioning system. When this line becomes plugged with dirt, particles or mold, water can back up and start to come out of the unit.

Another possible explanation for water leaking from an air conditioner is a malfuncitoning or rusted drip pan, which can allow water to overflow and leak out of the unit. In addition, a refrigerant leak or a malfunctioning pump could 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 be certain that your air conditioning system is operating efficiently. Regular 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 occurring.

Why Does My Air Conditioner Freeze Up?

If your AC is freezing up, it may be due to a variety of reasons. One common cause of a frozen air conditioner is restricted airflow, which can be caused by a blocked air filter, obstructed ductwork or closed vents. This leads to a buildup of frigid 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 really cold and freeze. Leaking ducts or cracked insulation can also result in the buildup of chilled air and cause the evaporator coil to freeze.

To fix a frozen air conditioner, it's important to switch off the system 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 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 might be a sign that it needs service. One prevalent cause of a very loud air conditioner is a broken fan motor or a worn-out fan belt. The racket could 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 might have a dirty condenser coil, which can hinder airflow and cause the system to work harder, resulting in greater noise. Additionally, a defective or old compressor can also be a reason you hear loud noises from the air conditioner.

Why Is My AC System Not Blowing Cold Air?

One common cause of an air conditioning system not blowing cold air is a blocked air filter. A dirty air filter restricts airflow, causing the evaporator coil to become very cold and freeze, resulting in insufficient cool air. Another potential reason for this problem 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 AC. Additionally, a faulty compressor or motor can also cause the AC not to blow cold air. To fix the issue, it's important to inspect the air filter and change it if necessary.

Why Won't My Air Conditioner Run or Start?

An air conditioner might not start up because of a tripped circuit breaker or blown fuse. To repair this, find the electrical panel and reset any tripped breakers or change any blown fuses.

Another possible cause is a malfunctioning thermostat, which can keep the air conditioner from turning on. If that's the case, check the thermostat and change it, if necessary. Also, a faulty compressor, motor or capacitor can keep 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 operating louder than they are supposed to, sometimes they also make peculiar noises.

One common cause of weird noises is a broken fan motor or a worn-out fan belt. These two issues can produce scraping, squealing or grinding noises. Yet another commonly observed 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 cause hissing or bubbling noises.

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