Is your air conditioning 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 type of issue the system is experiencing. Whether it’s peculiar noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a specific fix. By knowing the specific symptoms, you can identify the potential causes of the problem and determine the best course of action for repairing the air conditioning system.

While the symptoms are often distinct, 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 locating any parts that may be wearing out and need replacement or to be fixed. This helps find potential problems before they cause breakdowns or other issues.

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

Why Does My Air Conditioner Leak?

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

Another potential cause of water leaking from an air conditioner is a malfuncitoning or rusted drip pan, which can permit water to overflow and leak out of the unit. Additionally, 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 reduce the amount of damage to your home and be certain that your air conditioning system is running efficiently. Routine air conditioner maintenance, including exchanging 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 Does My Air Conditioner Freeze Up?

If your air conditioner is freezing up, it may stem from a variety of reasons. One common cause of a frozen air conditioner is restricted airflow, which can be caused by a plugged air filter, obstructed ductwork or closed vents. This can cause a buildup of frigid air in the evaporator coil, causing it to freeze.

Another reason your air conditioner is frozen might be low refrigerant levels, which can cause the evaporator coil to become really cold and freeze. Leaking ducts or cracked insulation can also lead to the buildup of frosty air and cause the evaporator coil to freeze.

To fix a frozen air conditioner, it's important to turn off the air conditioner so that 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 skilled technician.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it might be an indication that your AC needs service. One frequent cause of a very loud air conditioner is a damaged fan motor or a failing fan belt. The noise could 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 prevent airflow and cause the system to work harder, resulting in increased noise. Additionally, a damaged or old compressor can also be a reason you hear loud noises from the air conditioner.

Why Is My Air Conditioner Not Blowing Cold Air?

One common cause of an air conditioning system not making cold air is a clogged air filter. A dirty air filter restricts airflow, causing the evaporator coil to become too cold and freeze, resulting in not enough cool air. Another potential reason for this problem 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. Additionally, a faulty compressor or motor can also cause a lack of cool air. To rectify 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 fix this, find the electrical panel and reset any tripped breakers or switch out any blown fuses.

The cause also could be a malfunctioning thermostat, which can prevent the air conditioner from turning on. In that case, check the thermostat and substitute it with a new one, if required. Also, a malfunctioning compressor, motor or capacitor can stop the air conditioner from turning on. In this case, it's best to get a hold of 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 ought to, occasionally they also make peculiar noises.

One common cause of weird noises is a broken fan motor or a worn-out fan belt. These two problems can produce scraping, squealing or grinding noises. One other commonly observed cause is loose parts such as screws, bolts or bearings.

Additionally, a blocked air filter can cause whistling or wheezing noises from an air conditioner, while a refrigerant leak can cause hissing or bubbling noises.

As with lots of air conditioner problems, the root cause of uncommon noises is often something that can be reduced by regular air conditioning maintenance.
