Is your AC 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 kind of issue the system is afflicted with. Whether it’s odd noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a distinct remedy. By identifying the specific symptoms, you can narrow down 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 annual air conditioning maintenance. That’s because a routine Air conditioning 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 find potential problems before they cause malfunctions or other issues.

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

Why Does My Air Conditioner Leak?

A cooling system 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 is supposed to take away extra moisture from the air conditioning system. When this line becomes clogged with dirt, debris or mold, water can back up and start to come out of the unit.

Another typical cause of 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. Also, a refrigerant leak or a broken pump might also cause water to leak from an AC unit.

It's crucial to address a leaking air conditioner quickly 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, taking a look at the condensate drain line and inspecting the unit for damage can help prevent leaks from occurring.

Why Does My Air Conditioner Freeze Up?

If your air conditioning 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 frigid air in the evaporator coil, causing it to freeze.

One more reason your air conditioner is frozen might be insufficient refrigerant levels, which can cause the evaporator coil to become very cold and freeze. Leaking ducts or damaged insulation can also result in 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 air conditioning so that it can thaw completely. When the system has thawed, check 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 a professional.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it might be a signal that the unit needs service. One frequent cause of a noisy air conditioner is a damaged fan motor or a worn-out fan belt. The loudness might 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 could have a dirty condenser coil, which can hinder airflow and cause the system to work harder, resulting in more noise. Additionally, a broken or old compressor can also be a reason you hear loud noises from the air conditioner.

Why Is My AC System Not Blowing Cold Air?

One common cause of an air conditioner not making cold air is a very dirty air filter. A dirty air filter limit airflow, causing the evaporator coil to become very cold and freeze, resulting in insufficient cool air. Another plausible source of this issue is a refrigerant leak.

Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, which can result in a lack of cool air coming from your AC. In addition, a faulty compressor or motor can also cause the AC not to blow cold air. To address the issue, it's important to inspect the air filter and change it if necessary.

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

Your air conditioning system might not start up 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.

The source of the issue also could be a malfunctioning thermostat, which can keep the air conditioner from turning on. If that's the 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. In this case, it's best to get a hold of a professional to inspect and service the unit.

Why Does My Air Conditioner Make Weird Noises?

In addition to the problem of air conditioners operating louder than they ought to, sometimes they also make peculiar noises.

One typical cause of weird noises is a malfunctioning fan motor or a worn-out fan belt. These two issues can cause scraping, squealing or grinding noises. One other possible cause is loose parts such as screws, bolts or bearings.

Additionally, a dirty air filter can cause an AC to make whistling or wheezing noises, while a refrigerant leak can produce hissing or bubbling noises.

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