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

The symptoms of an air conditioner’s problem can tell a lot about the kind of issue the system is afflicted with. Whether it’s weird noises, leaks, freezing up or another breakdown—it all points to a particular culprit and requires a distinct remedy. By recognizing the specific symptoms, you can narrow down the potential causes of the problem and determine the best course of action for repairing the air conditioning system.

While the symptoms are often very different, 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 looking for any parts that may be wearing out and need replacement or to be fixed. This helps uncover potential problems before they cause breakdowns or other issues.

Here are a few of the typical AC problems and the signs you may see:

Why Do AC Systems Leak?

A cooling system leaking water can be a widespread issue. One of the most common causes of an AC leak is a clogged condensate drain line. The condensate drain line is is supposed to take away extra moisture from the air conditioning system. When this line becomes clogged with dirt, dust or mold, water can back up and start to escape.

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

It's important to address a leaking air conditioner right away to prevent damage to your home and be certain that your air conditioning system is running efficiently. Professional air conditioner maintenance, including replacing the air filter, examining 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 could stem from a variety of reasons. One typical cause of a frozen air conditioner is limited airflow, which can be caused by a plugged air filter, obstructed ductwork or closed vents. This can cause a buildup of chilled air in the evaporator coil, causing it to freeze.

One more reason your air conditioner is frozen might be low refrigerant levels, which can cause the evaporator coil to become too cold and freeze. Leaking ducts or compromised 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 turn off the air conditioner so that it can thaw completely. When the system has thawed, assess the air filter, ductwork and refrigerant levels to see if something is broken. Regular maintenance, including exchanging the air filter and having the system inspected annually by a skilled technician.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it could be a signal that your AC needs service. One frequent cause of a very loud air conditioner is a damaged fan motor or a failing fan belt. The loudness 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 could have a dirty condenser coil, which can hinder airflow and cause the system to work harder, resulting in increased noise. Additionally, a broken or old compressor can also be a reason you hear loud noises from the air conditioner.

Why Won'y My Air Conditioning Blow Cold Air?

One common cause of an AC not making cold air is a clogged air filter. A dirty air filter restricts airflow, causing the evaporator coil to become too cold and freeze, resulting in not enough cool air. Another possible reason for this problem is a refrigerant leak.

Low refrigerant levels may also cause the evaporator coil to become too cold and freeze, resulting in a lack of cool air coming from your AC. Additionally, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To rectify this particular problem, 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 turn on because of a tripped circuit breaker or blown fuse. To correct this, check 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 stop the air conditioner from switching on. In this case, check the thermostat and substitute it with a new one, if required. Also, a malfunctioning compressor, motor or capacitor can keep the air conditioner from turning on. To address this issue, it's best to get a hold of a professional to inspect and service the unit.

Why Is My Air Conditioner Making a Weird Noise?

In addition to the problem of air conditioners operating louder than they should, at times they also make strange noises.

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

Furthermore, 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 lots of air conditioner woes, the root cause of odd noises is often something that can be reduced by regular air conditioning maintenance.
