Is your air conditioner acting strange? Chances are, it’s trying to tell you something.

The warning signs of an air conditioner’s problem can tell a lot about the type of issue the system is suffering from. Whether it’s odd noises, leaks, freezing up or another breakdown—it all points to a particular culprit and requires a unique repair. By knowing 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 routine air conditioning maintenance. That’s because a routine AC 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 service. This helps find potential problems before they cause breakdowns or other issues.

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

Why Does My Air Conditioner Leak?

Air conditioning leaking water can be a frequent 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 unwanted moisture from the air conditioning system. When this line becomes slow or stopped up with dirt, particles or mold, water can back up and start to escape.

Another potential 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 necessary to address a leaking air conditioner quickly to reduce the amount of damage to your home and ensure that your air conditioning system is operating efficiently. Routine air conditioner maintenance, including exchanging 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 air conditioning is freezing up, it might be because of a variety of reasons. One frequent cause of a frozen air conditioner is limited airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This leads to a buildup of cold 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 result in 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 conditioning so it can thaw completely. After the system has thawed, examine the air filter, ductwork and refrigerant levels to see if anything is malfunctioning. Regular maintenance, including exchanging the air filter and having the system inspected annually by an expert.

Why Does My Air Conditioner Make So Much Noise?

If your air conditioner is making loud noises, it might be an indication that the unit needs service. One prevalent cause of a loud 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 could have a dirty condenser coil, which can obstruct airflow and cause the system to work harder, resulting in greater noise. Additionally, a defective or old compressor can also produce loud noises from the air conditioner.

Why Won'y My Air Conditioning Blow Cold Air?

One common cause of an air conditioner not producing cold air is a blocked air filter. A dirty air filter limit airflow, causing the evaporator coil to become too cold and freeze, resulting in insufficient cool air. Another possible reason for this problem is a refrigerant leak.

Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, leading to 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 fix this, it's important to inspect the air filter and replace it if necessary.

Why Won't My Air Conditioner Run or Start?

An air conditioner might not start up because of a tripped circuit breaker or blown fuse. To fix this, inspect the electrical panel and reset any tripped breakers or change any blown fuses.

Another possible cause is 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 necessary. In addition, a malfunctioning compressor, motor or capacitor can prevent the air conditioner from turning on. If that's the situation, it's best to get a hold of a professional to inspect and fix the unit.

Should My Air Conditioner Be Making a Loud Noise?

In addition to the problem of air conditioners running louder than they should, occasionally they also make weird noises.

One typical cause of weird noises is a deteriorating fan motor or a worn-out fan belt. These two problems can produce scraping, squealing or grinding noises. Another potential cause is loose parts such as screws, bolts or bearings.

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

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