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

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

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 to be fixed. This helps locate potential problems before they cause malfunctions or other issues.

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

Why Does My Air Conditioner Leak?

Air conditioning leaking water can be a frequent issue. One of the most common causes of an air conditioner leak is a plugged condensate drain line. The condensate drain line is is supposed to take away extra 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 explanation for 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. In addition, a refrigerant leak or a malfunctioning pump can also cause water to leak from an AC unit.

It's important to address a leaking air conditioner right away to avoid damage to your home and ensure that your air conditioning system is running efficiently. Routine air conditioner maintenance, including changing the air filter, examining 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 may be because of a variety of reasons. One typical cause of a frozen air conditioner is reduced airflow, which can be caused by a clogged 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 low refrigerant levels, which can cause the evaporator coil to become really cold and freeze. Leaking ducts or cracked 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 turn off the air conditioning 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 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 noise 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 could have a dirty condenser coil, which can block airflow and cause the system to work harder, resulting in greater noise. Similarly, a broken 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 AC not making cold air is a very dirty air filter. A dirty air filter restricts airflow, causing the evaporator coil to become very cold and freeze, resulting in a lack of 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 AC. Also, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To fix this particular problem, it's important to examine the air filter and change it if necessary.

Why Can't My Air Conditioner Run or Even Turn On?

An air conditioner might not start up because of a tripped circuit breaker or blown fuse. To fix 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 switching on. In that case, check the thermostat and replace it, if necessary. In addition, a malfunctioning 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 service the unit.

Why Is My Air Conditioner Making a Weird Noise?

In addition to the problem of air conditioners running louder than they should, sometimes they also make strange noises.

One typical 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 possible cause is loose parts such as screws, bolts or bearings.

In addition, 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 problems, the root cause of strange noises is often something that can be reduced by regular air conditioning maintenance.
