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

The signs of an air conditioner’s problem can tell a lot about the kind of issue the system is suffering from. Whether it’s weird noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a distinct fix. By recognizing the specific symptoms, you can narrow down 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 conditioner 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 repair. This helps uncover potential problems before they cause breakdowns or other issues.

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

Why Is My Air Conditioner Leaking?

Air conditioning leaking water can be a common issue. One of the most common causes of an air conditioner 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 slow or stopped up with dirt, dust or mold, water can back up and start to escape.

Another typical reason for water leaking from an air conditioner is a broken or rusted drip pan, which can enable water to overflow and leak out of the unit. Also, a refrigerant leak or a busted pump can also cause water to leak from an AC unit.

It's important to address a leaking air conditioner right away to reduce the amount of damage to your home and make sure that your air conditioning system is running efficiently. Regular air conditioner maintenance, including exchanging the air filter, examining the condensate drain line and inspecting the unit for damage can help prevent leaks from occurring.

Why Is My Air Conditioner Freezing Up?

If your air conditioning is freezing up, it could be because of a variety of reasons. One typical cause of a frozen air conditioner is limited airflow, which can be caused by a plugged air filter, obstructed ductwork or closed vents. This leads to a buildup of cold air in the evaporator coil, causing it to freeze.

Another reason your air conditioner is frozen might be reduced refrigerant levels, which can cause the evaporator coil to become too cold and freeze. Leaking ducts or compromised 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 turn off the air conditioning so it can thaw completely. When the system has thawed, check the air filter, ductwork and refrigerant levels to see if something is broken. Regular maintenance, including exchanging 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 could be a sign that your AC needs service. One frequent cause of a very loud air conditioner is a malfunctioning fan motor or a damaged fan belt. The noise can also be caused by 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 obstruct airflow and cause the system to work harder, resulting in more noise. Additionally, a defective 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 blocked air filter. A dirty air filter can significantly slow airflow, causing the evaporator coil to become very cold and freeze, resulting in not enough cool air. Another potential source of this issue is a refrigerant leak.

Low refrigerant levels may also cause the evaporator coil to become too cold and freeze, which can result in a lack of cool air coming from your air conditioning. Also, a faulty compressor or motor can also cause a lack of cool air. To address this particular problem, it's important to examine 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 correct this, look at the electrical panel and reset any tripped breakers or change any blown fuses.

The cause also could be a malfunctioning thermostat, which can prevent the air conditioner from starting. In that case, check the thermostat and change it, if necessary. Also, a malfunctioning compressor, motor or capacitor can prevent the air conditioner from turning on. To address this issue, it's best to get in touch with 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 problems can make scraping, squealing or grinding noises. Yet another potential cause is loose parts such as screws, bolts or bearings.

In addition, a dirty air filter can cause your air conditioning to make a noise similar to wheezing or whistling, while a refrigerant leak can cause hissing or bubbling noises.

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