Is your air conditioner acting strange? 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 type of issue the system is suffering from. Whether it’s weird noises, leaks, freezing up or another breakdown—it all points to a particular culprit and requires a unique remedy. By identifying the specific symptoms, it's more likely that you'll be able to figure out the potential causes of the problem and determine the best course of action for repairing the AC.

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 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 repair. This helps locate potential problems before they cause breakdowns or other issues.

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

Why Do AC Systems Leak?

Air conditioning 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 is supposed to take away excess moisture from the air conditioning system. When this line becomes slow or stopped up with dirt, debris or mold, water can back up and start to leak.

Another typical cause of 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 busted pump could also cause water to leak from an AC unit.

It's crucial to address a leaking air conditioner promptly to avoid damage to your home and be certain that your air conditioning system is running 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 developing in the future.

Why Does My Air Conditioner Freeze Up?

If your AC is freezing up, it may stem from a variety of reasons. One common cause of a frozen air conditioner is reduced airflow, which can be caused by a plugged 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 cracked insulation can also cause the buildup of chilled 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. When the system has thawed, assess the air filter, ductwork and refrigerant levels to see if anything is malfunctioning. Regular maintenance, including changing 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 may be a signal that your AC needs service. One prevalent cause of a noisy air conditioner is a broken 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 obstruct airflow and cause the system to work harder, resulting in increased noise. In addition, a defective or old compressor can also produce 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 restricts airflow, causing the evaporator coil to become extremely cold and freeze, resulting in insufficient cool air. Another potential source of this issue is a refrigerant leak.

Low refrigerant levels may also cause the evaporator coil to become too cold and freeze, resulting in a lack of cool air coming from your air conditioner. Also, a faulty compressor or motor can also cause a lack of cool air. To rectify the issue, it's important to check the air filter and exchange it if necessary.

Why Won't My Air Conditioner Run or Start?

A home cooling 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 switch out any blown fuses.

Another possible cause is a malfunctioning thermostat, which can prevent the air conditioner from starting. In this case, check the thermostat and replace it, if necessary. Also, a faulty compressor, motor or capacitor can stop the air conditioner from turning on. If that's the situation, it's best to get a hold of 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 operating louder than they are supposed to, sometimes they also make strange noises.

One common cause of weird noises is a malfunctioning fan motor or a worn-out fan belt. These two dilemmas can cause scraping, squealing or grinding noises. One other commonly observed 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 uncommon noises is often something that can be reduced by regular air conditioning maintenance.
