Is your air conditioner acting strange? 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 sort of issue the system is afflicted with. Whether it’s peculiar noises, leaks, freezing up or another breakdown—it all points to a particular culprit and requires a unique fix. By identifying the specific symptoms, it's possible to 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 very different, many cooling system issues stem from problems that can be avoided by scheduling routine air conditioning maintenance. That’s because a routine Air conditioner maintenance call includes an inspection and cleaning of your system, as well as looking for any parts that may be wearing out and need replacement or to be fixed. This helps locate potential problems before they cause equipment failures or other issues.

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

Why Do AC Systems Leak?

An air conditioner leaking water can be a widespread 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 excess 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 come out of the unit.

Another typical cause of 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. In addition, a refrigerant leak or a broken pump can also cause water to leak from an AC unit.

It's crucial to address a leaking air conditioner promptly to avoid damage to your home and be certain that your air conditioning system is running efficiently. Routine air conditioner maintenance, including exchanging the air filter, checking the condensate drain line and inspecting the unit for damage can help prevent leaks from occurring.

Why Does My Air Conditioner Freeze Up?

If your air conditioning is freezing up, it may be because of a variety of reasons. One typical 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 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 compromised insulation can also cause 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 system and allow it to thaw completely. When the system has thawed, check 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 professional.

Why Is My Air Conditioner So Loud?

If your air conditioner is making loud noises, it may be a signal that your AC needs service. One common cause of a noisy air conditioner is a malfunctioning 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 hinder airflow and cause the system to work harder, resulting in increased noise. Similarly, a broken 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 conditioner not blowing cold air is a very dirty air filter. A dirty air filter restricts airflow, causing the evaporator coil to become too cold and freeze, resulting in a lack of cool air. Another plausible cause 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. Also, 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 replace it if necessary.

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

Your air conditioning system might not switch on because of a tripped circuit breaker or blown fuse. To repair this, find the electrical panel and reset any tripped breakers or switch out any blown fuses.

The source of the issue also could be a malfunctioning thermostat, which can stop the air conditioner from starting. If that's the case, check the thermostat and substitute it with a new one, if necessary. In addition, a problematic compressor, motor or capacitor can stop the air conditioner from turning on. To address this issue, it's best to contact a professional to inspect and repair the unit.

Why Does My Air Conditioner Make Weird Noises?

In addition to the problem of air conditioners operating louder than they ought to, at times they also make weird noises.

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

Additionally, a blocked air filter can cause an AC to make whistling or wheezing noises, while a refrigerant leak can produce hissing or bubbling noises.

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