Is your air conditioning acting weird? 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 afflicted with. Whether it’s odd noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a distinct fix. By knowing 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 routine 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 repair. This helps uncover potential problems before they cause malfunctions or other issues.

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

Why Is My Air Conditioner Leaking?

An air conditioner leaking water can be a widespread issue. One of the most common causes of an AC leak is a plugged condensate drain line. The condensate drain line is designed to remove unwanted moisture from the air conditioning system. When this line becomes plugged with dirt, debris or mold, water can back up and start to escape.

Another typical 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. Additionally, a refrigerant leak or a busted 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 ensure that your air conditioning system is running efficiently. Regular air conditioner maintenance, including changing the air filter, taking a look at the condensate drain line and inspecting the unit for damage can help prevent leaks from developing in the future.

Why Is My Air Conditioner Freezing Up?

If your air conditioner is freezing up, it may 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 frigid 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 damaged 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 power down the system so that 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 an expert.

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 common cause of a loud air conditioner is a malfunctioning fan motor or a failing fan belt. The loudness can 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 prevent airflow and cause the system to work harder, resulting in greater noise. In addition, 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 air conditioner not making cold air is a clogged air filter. A dirty air filter can significantly slow airflow, causing the evaporator coil to become extremely cold and freeze, resulting in insufficient cool air. Another possible reason for this problem is a refrigerant leak.

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

Why Is My Air Conditioner Not Working or Not Turning On?

Your air conditioning system might not turn on because of a tripped circuit breaker or blown fuse. To repair this, check the electrical panel and reset any tripped breakers or replace any blown fuses.

Another possible cause is a malfunctioning thermostat, which can stop the air conditioner from turning on. In this case, check the thermostat and replace it, if necessary. Additionally, a problematic compressor, motor or capacitor can keep the air conditioner from turning on. In this case, it's best to get in touch with a professional to inspect and fix 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 weird noises.

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

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