Is your air conditioner acting weird? If so, it's good to pay attention because 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 distinct fix. 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 unit.

While the symptoms are often very different, 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 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 the common AC problems and the signs you may see:

Why Does My Air Conditioner Leak?

Air conditioning leaking water can be a common issue. One of the most common causes of an AC leak is a clogged condensate drain line. The condensate drain line is designed to remove unwanted moisture from the air conditioning system. When this line becomes clogged with dirt, particles 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 allow 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 quickly to reduce the amount of damage to your home and make sure that your air conditioning system is running efficiently. Routine air conditioner maintenance, including changing the air filter, checking the condensate drain line and inspecting the unit for damage can help prevent leaks from happening.

Why Does My Air Conditioner Freeze Up?

If your air conditioning is freezing up, it could stem from a variety of reasons. One typical cause of a frozen air conditioner is reduced airflow, which can be caused by a plugged air filter, obstructed ductwork or closed vents. This can cause 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 damaged insulation can also cause 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 and allow it to thaw completely. Once the system has thawed, examine the air filter, ductwork and refrigerant levels to see if anything is amiss. Regular maintenance, including changing 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 might be a signal that it needs service. One common cause of a loud air conditioner is a damaged fan motor or a worn-out fan belt. The noise might 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 may 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 cause loud noises from the air conditioner.

Why Is My AC System Not Blowing Cold Air?

One common cause of an air conditioner not blowing cold air is a clogged air filter. A dirty air filter can significantly slow airflow, causing the evaporator coil to become too cold and freeze, resulting in a lack of cool air. Another possible source of this issue is a refrigerant leak.

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

Why Won't My Air Conditioner Run or Start?

Your air conditioning system might not switch on because of a tripped circuit breaker or blown fuse. To correct this, inspect the electrical panel and reset any tripped breakers or change 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 replace it, if needed. In addition, a faulty 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.

Should My Air Conditioner Be Making a Loud Noise?

In addition to the problem of air conditioners working louder than they are supposed 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 make scraping, squealing or grinding noises. One other commonly observed cause is loose parts such as screws, bolts or bearings.

Furthermore, a clogged air filter can cause whistling or wheezing noises from an air conditioner, while a refrigerant leak can make hissing or bubbling noises.

As with a lot of air conditioner woes, the root cause of strange noises is often something that can be reduced by regular air conditioning maintenance.
