Is your air conditioning acting strange? 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 kind 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 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 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 to be fixed. This helps locate potential problems before they cause breakdowns or other issues.

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

Why Is My Air Conditioner Leaking?

A cooling system 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 designed to remove excess moisture from the air conditioning system. When this line becomes slow or stopped up with dirt, debris 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 enable water to overflow and leak out of the unit. Also, a refrigerant leak or a broken pump could also cause water to leak from an AC unit.

It's necessary to address a leaking air conditioner right away to reduce the amount of damage to your home and ensure that your air conditioning system is functioning efficiently. Professional 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 conditioner is freezing up, it could be due to a variety of reasons. One common cause of a frozen air conditioner is restricted 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.

An additional 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 lead to 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 system so it can thaw completely. Once 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 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 common cause of a very loud air conditioner is a malfunctioning fan motor or a failing fan belt. The racket might 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 block airflow and cause the system to work harder, resulting in greater noise. Similarly, a damaged or old compressor can also cause loud noises from the air conditioner.

Why Is My Air Conditioner Not Blowing Cold Air?

One common cause of an AC not producing cold air is a blocked air filter. A dirty air filter restricts airflow, causing the evaporator coil to become extremely cold and freeze, resulting in a lack of 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 conditioning. Also, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To rectify this, it's important to examine the air filter and change 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 correct this, find the electrical panel and reset any tripped breakers or replace any blown fuses.

The source of the issue also could be a malfunctioning thermostat, which can prevent the air conditioner from switching on. In that case, check the thermostat and substitute it with a new one, if required. Additionally, a problematic compressor, motor or capacitor can keep the air conditioner from turning on. To address this issue, it's best to get in touch with 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 running louder than they are supposed to, sometimes they also make strange noises.

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

In addition, 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 predicaments, the root cause of odd noises is often something that can be reduced by regular air conditioning maintenance.
