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

The warning signs of an air conditioner’s problem can tell a lot about the type of issue the system is experiencing. Whether it’s peculiar noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a distinct repair. 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 unit.

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 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 malfunctions or other issues.

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

Why Does My Air Conditioner Leak?

An air conditioner leaking water can be a widespread issue. One of the most common causes of an AC leak is a clogged condensate drain line. The condensate drain line is responsible for removing unwanted 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 escape.

Another possible explanation for water leaking from an air conditioner is a broken 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 could also cause water to leak from an AC unit.

It's necessary to address a leaking air conditioner promptly to reduce the amount of damage to your home and make sure that your air conditioning system is operating efficiently. Regular 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.

What's the Reason My Air Conditioner Freezes Up?

If your air conditioning is freezing up, it might be because of a variety of reasons. One frequent cause of a frozen air conditioner is reduced airflow, which can be caused by a clogged air filter, obstructed ductwork or closed vents. This leads to a buildup of chilled 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 very cold and freeze. Leaking ducts or cracked insulation can also result in the buildup of frosty air and cause the evaporator coil to freeze.

To fix a frozen air conditioner, it's important to switch off the air conditioning so that it can thaw completely. Once the system has thawed, examine the air filter, ductwork and refrigerant levels to see if anything is amiss. Regular maintenance, including replacing the air filter and having the system inspected annually by a professional.

Is My Air Conditioner Supposed to Be Loud?

If your air conditioner is making loud noises, it might be an indication that the unit needs service. One frequent cause of a very loud air conditioner is a broken fan motor or a failing fan belt. The noise could 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 might have a dirty condenser coil, which can hinder airflow and cause the system to work harder, resulting in more noise. Additionally, a defective or old compressor can also produce loud noises from the air conditioner.

Why Is My AC System 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 too cold and freeze, resulting in not enough cool air. Another plausible reason for this problem is a refrigerant leak.

Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, leading to 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 particular problem, it's important to examine the air filter and exchange 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 switch out any blown fuses.

Another possible cause is a malfunctioning thermostat, which can prevent the air conditioner from starting. In this case, check the thermostat and replace it, if needed. In addition, a malfunctioning compressor, motor or capacitor can stop 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.

Should My Air Conditioner Be Making a Loud Noise?

In addition to the problem of air conditioners running louder than they should, sometimes 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 produce scraping, squealing or grinding noises. Another possible cause is loose parts such as screws, bolts or bearings.

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

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