Is your air conditioning 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 type 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 specific remedy. By recognizing 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 unique, many cooling system issues stem from problems that can be avoided by scheduling routine air conditioning maintenance. That’s because a routine Air conditioner 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 find potential problems before they cause malfunctions or other issues.

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

Why Do AC Systems Leak?

An air conditioner leaking water can be a common issue. One of the most common causes of an AC 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 clogged with dirt, particles or mold, water can back up and start to escape.

Another possible explanation for water leaking from an air conditioner is a broken or rusted drip pan, which can permit 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 important to address a leaking air conditioner right away to reduce the amount of damage to your home and be certain that your air conditioning system is functioning efficiently. Professional 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 air conditioning is freezing up, it could be because of a variety of reasons. One frequent cause of a frozen air conditioner is reduced airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This sometimes causes a buildup of cold air in the evaporator coil, causing it to freeze.

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

To fix a frozen air conditioner, it's important to turn off the system and allow it to thaw completely. When the system has thawed, assess 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.

Is My Air Conditioner Supposed to Be Loud?

If your air conditioner is making loud noises, it may be a sign that it needs service. One prevalent cause of a noisy air conditioner is a malfunctioning fan motor or a worn-out 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 might have a dirty condenser coil, which can block airflow and cause the system to work harder, resulting in increased 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 AC not producing cold air is a very dirty 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 reason for this problem is a refrigerant leak.

Low refrigerant levels might also cause the evaporator coil to become too cold and freeze, resulting in a lack of cool air coming from your air conditioning. Also, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To address the issue, it's important to inspect the air filter and change it if necessary.

Why Won't My Air Conditioner Run or Start?

Your air conditioning system might not turn on because of a tripped circuit breaker or blown fuse. To correct this, find 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 replace it, if required. Additionally, a malfunctioning compressor, motor or capacitor can prevent the air conditioner from turning on. If that's the situation, it's best to contact 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 should, at times they also make peculiar noises.

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

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