Is your air conditioning acting weird? There's a good chance it’s trying to tell you something.

The warning signs of an air conditioner’s problem can tell a lot about the sort of issue the system is afflicted with. Whether it’s weird noises, leaks, freezing up or another ailment—it all points to a particular culprit and requires a distinct fix. By knowing the specific symptoms, it's more likely that you'll be able to narrow down the potential causes of the problem and determine the best course of action for repairing the AC.

While the symptoms are often distinct, many cooling system issues stem from problems that can be avoided by scheduling regular air conditioning maintenance. That’s because a routine Air conditioning maintenance call includes an inspection and cleaning of your system, as well as finding any parts that may be wearing out and need replacement or repair. This helps find potential problems before they cause equipment failures or other issues.

Here are a few of the top AC problems and the signals you may see:

Why Is My Air Conditioner Leaking?

A cooling system leaking water can be a common 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 unwanted moisture from the air conditioning system. When this line becomes plugged with dirt, debris or mold, water can back up and start to come out of the unit.

Another possible explanation for water leaking from an air conditioner is a malfuncitoning or rusted drip pan, which can permit water to overflow and leak out of the unit. In addition, a refrigerant leak or a broken pump might also cause water to leak from an AC unit.

It's important to address a leaking air conditioner right away to prevent damage to your home and be certain 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 may be because of 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 can cause a buildup of cold air in the evaporator coil, causing it to freeze.

Another 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 cold air and cause the evaporator coil to freeze.

To fix a frozen air conditioner, it's important to power down the air conditioning so that 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 changing 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 a signal that your AC needs service. One common cause of a loud air conditioner is a broken fan motor or a failing fan belt. The noise can also be the result of 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 greater noise. Additionally, a broken or old compressor can also cause loud noises from the air conditioner.

Why Is My AC System Not Blowing Cold Air?

One common cause of an air conditioner not making cold air is a very dirty air filter. A dirty air filter can significantly slow airflow, causing the evaporator coil to become too cold and freeze, resulting in a lack of cool air. Another potential reason for this problem is a refrigerant leak.

Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, resulting in a lack of cool air coming from your air conditioning. Additionally, a faulty compressor or motor can also cause the AC not to blow cold air. To rectify this particular problem, it's important to inspect 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 switch on because of a tripped circuit breaker or blown fuse. To repair 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 keep the air conditioner from turning on. If that's the case, check the thermostat and substitute it with a new one, if required. Additionally, a faulty compressor, motor or capacitor can keep the air conditioner from turning on. In this case, it's best to get a hold of a professional to inspect and repair the unit.

Should My Air Conditioner Be Making a Loud Noise?

In addition to the problem of air conditioners working louder than they are supposed to, sometimes they also make peculiar noises.

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

Furthermore, 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 woes, the root cause of uncommon noises is often something that can be reduced by regular air conditioning maintenance.
