Is your AC acting weird? There's a good chance 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 experiencing. Whether it’s peculiar noises, leaks, freezing up or another breakdown—it all points to a particular culprit and requires a distinct repair. By identifying the specific symptoms, it's possible to identify 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 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 locate potential problems before they cause malfunctions or other issues.

Here are some 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 air conditioner leak is a plugged condensate drain line. The condensate drain line is is supposed to take away extra moisture from the air conditioning system. When this line becomes slow or stopped up with dirt, dust or mold, water can back up and start to come out of the unit.

Another possible explanation for water leaking from an air conditioner is a damaged or rusted drip pan, which can allow water to overflow and leak out of the unit. In addition, a refrigerant leak or a broken pump could also cause water to leak from an AC unit.

It's crucial to address a leaking air conditioner promptly to prevent damage to your home and be certain that your air conditioning system is running efficiently. Routine air conditioner maintenance, including replacing the air filter, examining 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 AC is freezing up, it might be due to a variety of reasons. One common cause of a frozen air conditioner is limited airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This can cause a buildup of chilled 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 really 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 switch off the air conditioning so it can thaw completely. Once the system has thawed, check the air filter, ductwork and refrigerant levels to see if something is broken. Regular maintenance, including replacing the air filter and having the system inspected annually by a skilled technician.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it may be a sign that the unit needs service. One common cause of a noisy air conditioner is a broken fan motor or a failing fan belt. The loudness could 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 may have a dirty condenser coil, which can hinder airflow and cause the system to work harder, resulting in more noise. In addition, a defective 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 AC not making cold air is a very dirty 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 potential 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 conditioning. Additionally, a faulty compressor or motor can also cause the AC not to blow cold air. To address this particular problem, it's important to examine the air filter and exchange it if necessary.

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

An air conditioner 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 switch out any blown fuses.

Another possible cause is a malfunctioning thermostat, which can prevent the air conditioner from switching on. In that case, check the thermostat and replace it, if required. Also, a faulty compressor, motor or capacitor can keep 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 working louder than they are supposed to, sometimes they also make peculiar noises.

One common 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. Another commonly observed 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 make 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.
