Is your air conditioner acting weird? If so, it's good to pay attention because it’s trying to tell you something.

The symptoms of an air conditioner’s problem can tell a lot about the sort 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 distinct fix. By identifying the specific symptoms, it's possible to figure out the potential causes of the problem and determine the best course of action for repairing the air conditioning system.

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 locating 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 common AC problems and the signs you may see:

Why Is My Air Conditioner Leaking?

An air conditioner leaking water can be a widespread issue. One of the most common causes of an AC leak is a plugged condensate drain line. The condensate drain line is responsible for removing excess moisture from the air conditioning system. When this line becomes clogged with dirt, debris or mold, water can back up and start to escape.

Another possible cause of 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 important to address a leaking air conditioner right away to avoid damage to your home and ensure that your air conditioning system is running 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 Is My Air Conditioner Freezing Up?

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

An additional reason your air conditioner is frozen might be low refrigerant levels, which can cause the evaporator coil to become very cold and freeze. Leaking ducts or compromised 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 switch off the air conditioner so it can thaw completely. After the system has thawed, examine the air filter, ductwork and refrigerant levels to see if anything is amiss. Regular maintenance, including exchanging 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 an indication that the unit needs service. One prevalent cause of a loud air conditioner is a broken fan motor or a damaged fan belt. The noise could also be caused by loose parts such as screws, bolts or bearings, which can cause vibrations and rattling sounds.

A noisy air conditioner also might have a dirty condenser coil, which can block airflow and cause the system to work harder, resulting in greater noise. Similarly, a defective or old compressor can also produce loud noises from the air conditioner.

Why Is My Air Conditioner Not Blowing Cold Air?

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

Low refrigerant levels might also cause the evaporator coil to become too cold and freeze, leading to a lack of cool air coming from your AC. Additionally, a faulty compressor or motor can also cause a lack of cool air. To address this, it's important to check the air filter and change it if necessary.

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

A home cooling system might not turn on because of a tripped circuit breaker or blown fuse. To repair this, look at the electrical panel and reset any tripped breakers or replace any blown fuses.

Another possible cause is a malfunctioning thermostat, which can stop the air conditioner from starting. In that case, check the thermostat and change it, if required. Additionally, a malfunctioning compressor, motor or capacitor can keep the air conditioner from turning on. In this case, it's best to contact a professional to inspect and repair the unit.

Why Is My Air Conditioner Making a Weird Noise?

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

One typical 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. Yet another potential cause is loose parts such as screws, bolts or bearings.

In addition, a clogged 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 strange noises is often something that can be reduced by regular air conditioning maintenance.
