Is your air conditioner acting unusual? Chances are, 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 suffering from. Whether it’s odd noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a distinct repair. By identifying the specific symptoms, it's more likely that you'll be able to 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 annual air conditioning maintenance. That’s because a routine AC 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 find potential problems before they cause equipment failures or other issues.

Here are some of of the top AC problems and the signs 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 plugged condensate drain line. The condensate drain line is responsible for removing extra moisture from the air conditioning system. When this line becomes clogged with dirt, debris or mold, water can back up and start to leak.

Another typical explanation for water leaking from an air conditioner is a broken 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 crucial to address a leaking air conditioner right away to avoid damage to your home and make sure that your air conditioning system is functioning efficiently. Routine air conditioner maintenance, including replacing the air filter, checking the condensate drain line and inspecting the unit for damage can help prevent leaks from happening.

What's the Reason My Air Conditioner Freezes Up?

If your AC is freezing up, it could be due to a variety of reasons. One common cause of a frozen air conditioner is reduced airflow, which can be caused by a blocked air filter, obstructed ductwork or closed vents. This leads to a buildup of cold air in the evaporator coil, causing it to freeze.

One more reason your air conditioner is frozen might be reduced refrigerant levels, which can cause the evaporator coil to become really cold and freeze. Leaking ducts or compromised insulation can also lead to 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 conditioning so it can thaw completely. After the system has thawed, check 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 professional.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it might be an indication that the unit needs service. One prevalent cause of a very loud air conditioner is a malfunctioning fan motor or a damaged fan belt. The loudness could also be caused by loose parts such as screws, bolts or bearings, which can cause vibrations and rattling sounds.

A noisy air conditioner also may have a dirty condenser coil, which can hinder airflow and cause the system to work harder, resulting in more noise. Additionally, a defective or old compressor can also cause loud noises from the air conditioner.

Why Won'y My Air Conditioning Blow Cold Air?

One common cause of an air conditioning system 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 source of this issue is a refrigerant leak.

Low refrigerant levels might also cause the evaporator coil to become too cold and freeze, leading to a lack of cool air coming from your air conditioner. In addition, a faulty compressor or motor can also cause a lack of cool air. To rectify the issue, it's important to inspect the air filter and change it if necessary.

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

A home cooling system might not start up because of a tripped circuit breaker or blown fuse. To correct this, inspect the electrical panel and reset any tripped breakers or switch out any blown fuses.

The cause also could be a malfunctioning thermostat, which can stop the air conditioner from turning on. In that case, check the thermostat and substitute it with a new one, if necessary. Also, a malfunctioning compressor, motor or capacitor can keep the air conditioner from turning on. To address this issue, it's best to get in touch with a professional to inspect and repair the unit.

Why Does My Air Conditioner Make Weird Noises?

In addition to the problem of air conditioners running louder than they ought 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 cause scraping, squealing or grinding noises. Yet another potential cause is loose parts such as screws, bolts or bearings.

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